Protect yourself from CryptoLocker

Over the years the nature of computer viruses has seen a change in focus. When the earliest reported example, Creeper, first appeared back in 1971 its sole purpose was to gain access to a system and display the message ‘I’m the Creeper, catch me if you can!’. Now, with so much valuable information about us stored on our computers and web services, something far darker has emerged. Ransomware is a new class of virus / trojan horse that has begun to appear on PCs in the last few years, and it is something you should be very concerned about.

The principle of Ransomware is simple. Usually it sneaks into a system disguised as an email attachment and, if opened, then proceeds to encrypt the files on your machine. When this has completed the virus deletes itself and tells the user that their data has been taken hostage and will only be released if they pay the demanded ransom for a key. These style of attacks were first reported in Russia back in 2004, with the Gpcode trojan horse. Security analysts at Kapersky labs were able to crack the hold Gpcode had over data by exploiting mistakes the author had made in the code.

Now it’s back and this time the encryption is rock solid.

Cryptolocker

CryptoLocker is the latest Ransomware virus to strike unsuspecting users, and so far it’s proven impossible to crack. What’s more, it doesn’t just take all the data on your hard drive.

“It also searches for files on all drives,” reported Steve Gibson on the Security Now podcast, “and in all folders it can access from your computer: including workgroup files shared by colleagues, resources on company servers, and more. Anything within its reach it encrypts…so if you have hot online backups they’re victims of this. Essentially the more privileged your account is, the worse the overall damage will be.”

When all of this is completed, Cryptolocker puts up its money demand page, complete with options of payment (Bitcoins or MoneyPak), usually for around three hundred Euros. There’s also a badly worded message telling you that your files have been encrypted and that any attempt to remove the software will destroy the only key that could possibly decrypt it. In a James Bond-style moment of drama the authors place a countdown clock, normally set for 72 hours, which immediately begins to tick down to the moment your data will be destroyed forever. Photos, videos, documents, music, pretty much anything at all that is on your hard drive, all gone.

The structure of the virus is such that it’s not actually possible to create a key for the encryption, because the data needed to do so is held only by the originators of the virus.

“The RSA encryption algorithm uses two keys: a public key and a private key.” explains Kapersky lab expert VitalyK on the Securelist website.  “Messages can be encrypted using the public key, but can only be decrypted using the private key. And this is how Gpcode works: it encrypts files on victim machines using the public key which is coded into its body. Once encrypted, files can only be decrypted by someone who has the private key – in this case, the author or the owner of the malicious program.”

The removal of the virus itself is of little use to the victim, and shutting down the server that holds the key will only result in the loss of the decryption tool, plus this is difficult because the servers switch location on a weekly basis. So most people who suffer a CryptoLocker attack are given the simple advice of either paying the ransom or losing the data, but like in any hostage situation you can never guarantee that the criminals will honour their terms.

Such is the increase of the CryptoLocker attacks in the UK that the National Crime Agency released a statement from its Cyber Crime unit in which it warned:

“The emails may be sent out to tens of millions of UK customers, but appear to be targeting small and medium businesses in particular. This spamming event is assessed as a significant risk.”

The complexity and sophistication of a program such as Cryptolocker is in itself an unsettling precedent. It suggests more than a simple bedroom hacker with impressive coding skills and little conscience, but instead has traces of the fast growing underworld of professional cyber criminals.

“Something of this size…is a well organised group.” says Stephen Doherty, Senior Threat Intelligence Analyst at Symantec. “There’d be dedicated segments to this, because its such a large and focussed operation. The distribution of Cryptolocker in recent weeks is as high, or higher, than most trojans you’d see out in the wild.”

The need for resources to actually run the scam is also a clue to size of the proponents.

“There’s a lot of stages to this,” Stephen continues, “to infect so many machines on an ongoing basis, and try to process all the money in the background. You’d want a well organised team behind you.”

How to protect yourself from a Cryptolocker attack

The rise of the interconnected digital world has brought with it problems that previously existed in the physical realms. From chancers who play on the innocence of victims, up to serious organised crime that has money, skills, cruel intentions and the willingness to use them on the unsuspecting public.

Take solace though, that we do have ways to protect ourselves from these evil spectres of the web.

The first, and most obvious, is to regularly run full backups of your valuable data and then remove the drive from your computer, preferably storing it off-site. See also: How to back up your PC and laptop

Another is to create several online backups via free services such as Dropbox, Google Drive, Skydrive, etc., which usually offer versioning – and thus a way to roll back to older versions of your files.

The most important though is to never, ever open a file or link in an email or on a social website unless you’re sure it was deliberately sent by the person themselves. It may seem interesting at the time, but the results could be utterly catastrophic.

Banks refuse to refund internet fraud victims

Bank customers urged to take more care of personal data

There are countless warnings from banks and police forces advising people to be careful what they download onto therir computers.

Foe example recently Gardaí advised that bank customers should not open phishing emails

Gardaí say they have seen a noticeable increase in cyber-criminals using “phishing” to steal money from people’s bank accounts.

internet search

Since January, up to 250 people have reported to gardaí that they have been victims of the crime.

The amounts stolen vary from €100 to €40,000.

Gardaí advise that bank customers should not open phishing emails, as they may contain a Trojan virus that will be downloaded to their computer.

If they do open one of these emails, they should contact their bank immediately.

They should also never respond to the phishing email under any circumstance.

Bank customers should also ensure their anti-virus software is up to date.

The Garda National Bureau of Fraud Investigation has said the thefts are being carried out by criminal cyber gangs over the web from various jurisdictions.

Some are using so called “mule” accounts in Ireland to transfer the stolen money into.

This can involve the gang paying unscrupulous individuals in Ireland small amounts of money for the use of their accounts, or the gangs themselves setting up their own Irish-based accounts.

Either way, money is transferred out of the victim’s account, into the mule’s account, before being withdrawn locally in Ireland and sent to the crime gangs abroad.

Gardaí say the gangs are based in a variety of locations, including West Africa and Eastern Europe.

However, using remote hosting technology, they can make the phishing emails appear to come from entirely different jurisdictions to the one they are living in.

Gardaí say in many cases banks refund the money that has been stolen.

However, this is not always the case, particularly in circumstances where the individual who has been defrauded has been warned about the dangers.

The Irish Payment Services Organisation has also noticed a spike in phishing crimes.

However, it says that a number of banks in Britain are now refusing to refund money stolen using this technique, because they claim they provide enough warning information to their customers.

One wonders how long before Irish Banks follow suit?

The emails appear to be from banks and financial organisations.

Millions of internet users in the UK are at “significant risk” from spam ransomware emails seemingly from banks and financial organisations.

The emails look like invoices or voicemails but in fact contain malware called Cryptolocker, which can encrypt files and the network, demanding payments in Bitcoins, worth about £536, to have it removed.

internet users hit by ransom email spam pc

The UK’s National Cyber Crime Unit (NCCU) warned that emails disguised as posts from banks and financial organisations are aimed at small and medium businesses and millions of bank customers.

In a statement, NCCU said: “This spamming event is assessed as a significant risk.

“The emails carry an attachment that appears to be correspondence linked to the email message (for example, a voicemail, fax, details of a suspicious transaction or invoices for payment).

“This file is in fact a malware that can install Cryptolocker – which is a piece of ransomware.”

NCCU deputy head Lee Miles said that the NCA are actively pursuing organised crime groups committing this crime. “We are working in cooperation with industry and international partners to identify and bring to justice those responsible and reduce the risk to the public,” he said.

Bitcoins have been increasingly targeted by cyber hackers, with about 4,100 Bitcoins valued at over a million Australian dollars being stolen from the online payment processor Inputs.io.

Suspected Malware Criminal Arrested

Blackhole malware exploit kit suspect arrested

Russian police have reportedly arrested a man on suspicion of masterminding two infamous hacking tools.

He is suspected of being the man behind the alias Paunch – the nickname used by the creator of the Blackhole and Cool exploit kits, sold to cybercriminals to infect web users with malware.

The Russian authorities have not confirmed the details.

But security firms said they had already detected a decline in the programs’ use.

A spokesman for the law enforcement agency Europol told the BBC: “Europol and the European Cybercrime Centre has been informed that a high-level suspected cyber criminal has been arrested.

“We can only refer you to the Russian authorities, they are the ones who should speak about this topic.”

The Russian police’s press office said it had nothing to add at this time.

However, Alexander Gostev, chief security expert at the Moscow-based internet protection provider Kaspersky Lab, said the arrest had been confirmed to him by “anonymous sources”.

Blackhole software The Blackhole kit offered an interface used to manage malware attacks

 

Spreading malware

The Blackhole kit, released in 2010, dominated the crimeware market throughout 2012 and the start of 2013, according to Fraser Howard, a researcher at the anti-virus company Sophos.

He said the code had been sold for an annual licence of $1,500 (£940) or could be rented from its creator for $200 (£125) for one week’s use, among other price plans.

The software targeted a range of vulnerabilities in the Java programming language, Adobe’s Flash media player, Windows software and PDF files.

It had two ways of doing this:

  • adding malicious code to hundreds of thousands of legitimate websites, which then copied malware to visitors computers
  • creating links in spam messages to specially created sites that infected PCs
Blackhole email
Sophos said that Blackhole was used to send links that directed users to sites that downloaded malware

Among the malware downloaded was:

  • fake anti-virus software that falsely claimed the PC was infected and urged the user to pay a fee to remove viruses
  • Trojans that attempted to steal financial records stored on the PC
  • the ZeroAccess rootkit, which downloaded other software that hijacked the PC for use in a botnet – a facility used to overwhelm websites with traffic and force them offline
  • key loggers that took a record of what was typed on the PC
  • ransomware that attempted to blackmail the PC owner

Although Mr Howard said Blackhole was once the biggest threat of its kind, he added that in recent months it had been overshadowed by rival kits, including Sweet Orange and Neutrino.

According to the researcher, the Blackhole and Cool kits put together were only involved in about 4% of all malware detected by Sophos in August, down from 28% the previous year.

The figure had since dropped to 2% in recent days, he added.

Another independent security blogger stressed that the arrest was still significant.

“If it’s true that the brains behind the Blackhole has been apprehended it’s a very big deal – a real coup for the cybercrime-fighting authorities, and hopefully cause disruption to the development of one of the most notorious exploit kits the web has ever seen,” said Graham Cluley.

“However, it’s worth remembering that nature abhors a vacuum, and there would surely be other online criminals waiting to take their place, promoting their alternative exploit kits and malicious code.”

Mikko Hypponen, chief research officer at F-Secure, agreed.

“If indeed it is Paunch that they arrested, that is a major arrest – he is a big deal,” he told the BBC.

“He was clearly the biggest player in providing exploit kits – not just by selling them, but also renting and leasing them to online criminals.

“Both Blackhole and its successor Cool have been very popular.

“Users didn’t have to be very technical to operate them – there was a manual that came with them – they just had to get them running and be able to break into a high-profile website, or create a new one from scratch, to install something bad on your computer.”

Suspected Malware Criminal Arrested – Irish Web Design

silk road caravan

Clandestine Silk Road online marketplace closed

The value of bitcoins has dropped after the closure of the clandestine Silk Road online marketplace.

The FBI seized bitcoins worth approximately $3.6m (£2.2m) on Tuesday.

The price of a bitcoin, a virtual currency for use online, fell steeply after the arrest of suspected website administrator Ross Ulbricht.

Investor confidence may have been shaken by the association of bitcoins with illegal activity, according to a security expert.

Visitors trying to access the Silk Road are now presented with a seizure notice

“When there’s a big bust, that’s going to knock people’s confidence in investing,” said Rik Ferguson, a senior researcher at security company Trend Micro.

“The more a currency is associated with illegal activity, the more people will be nervous about using it,” he said.

Silk Road, which allowed users to trade in illegal drugs, required transactions to be made using the virtual currency.

silk road closed down

US authorities believe that 29-year-old Ross William Ulbricht, arrested on Wednesday, is Dread Pirate Roberts (DPR) – the administrator of the notorious Silk Road online marketplace.

 

It was an underground website where people from all over the world were able to buy drugs.

In the months leading up to Mr Ulbricht’s arrest, investigators undertook a painstaking process of piecing together the suspect’s digital footprint, going back years into his history of communicating with others online.

The detail of how the FBI has built its case was outlined in a court complaint document published on Wednesday.

The search started with work from Agent-1, the codename given to the expert cited in the court documents, who undertook an “extensive search of the internet” that sifted through pages dating back to January 2011.

The trail began with a post made on a web forum where users discussed the use of magic mushrooms.

In a post titled “Anonymous market online?”, a user nicknamed Altoid started publicising the site.

“I came across this website called Silk Road,” Altoid wrote. “Let me know what you think.”

The post contained a link to a site hosted by the popular blogging platform WordPress. This provided another link to the Silk Road’s location on the so-called “dark web”.

Records obtained by Agent-1 from WordPress discovered, unsurprisingly, that the blog had been set up by an anonymous user who had hidden their location.

But then Altoid appeared in another place: a discussion site about virtual currency, bitcointalk.org.

Altoid – who the FBI claimed is Mr Ulbricht – was using “common online marketing” tactics. In other words, he was trying to make Silk Road go viral.

Months later, in October, Altoid appeared again – but made a slip-up, granting investigators a major lead.

In a post asking seeking to find an IT expert with knowledge of Bitcoin, he asked people to contact him via rossulbricht@gmail.com.

With a Gmail address to hand, Agent-1 linked this address to accounts on the Google+ social network and YouTube video site. There he discovered some of Mr Ulbricht’s interests.

Among them, according to the viewing history, was economics. In particular, Mr Ulbricht’s account had “favourited” several clips from the Ludwig von Mises Institute, a renowned Austrian school of economics.

Years later, on the Silk Road discussion forums, Dread Pirate Roberts would make several references to the Mises Institute and its work.

Covering tracks

According to the court complaint document, it was the discovery of the rossulbricht@gmail.com email address that gave investigators a major boost in their search.

Through records “obtained from Google”, details of IP addresses – and therefore locations – used to log into Mr Ulbricht’s account focused the search on San Francisco, specifically an internet cafe on Laguna Street.

Furthermore, detailed analysis of Silk Road’s source code highlighted a function that restricted who was able to log in to control the site, locking it down to just one IP address.

As would be expected, Dread Pirate Roberts was using a VPN – virtual private network – to generate a “false” IP address, designed to cover his tracks.

Google Streetview image of Hickory Street, San Francisco
Mr Ulbricht said to have been running Silk Road from Hickory Street in San Francisco

However, the provider of the VPN was subpoenaed by the FBI.

While efforts had been made by DPR to delete data, the VPN server’s records showed a user logged in from an internet cafe just 500 yards from an address on Hickory Street, known to be the home of a close friend of Mr Ulbricht’s, and a location that had also been used to log in to the Gmail account.

At this point in the investigation, these clues, investigators concluded, were enough to suggest that Mr Ulbricht and DPR – if not the same person – were at the very least in the same location at the same time.

Fake IDs

The court complaint went into detail about further leads that followed.

In July of this year, by coincidence, a routine border check of a package from Canada discovered forged documents for several fake identities all containing photographs of the same person.

It was headed to San Francisco’s 15th Street. Homeland security visited the address, and found the man in the photographs – Mr Ulbricht.

He told officers that the people he lived with knew him simply as Josh – one housemate described him as being “always home in his room on the computer”.

Around the same time, investigators working on the Silk Road case later discovered, DPR had been communicating with users privately to ask for advice on obtaining fake IDs – needed in order to purchase more servers.

Further activity attributed to Mr Ulbricht took place on Stack Overflow – a question-and-answer website for programmers – where a user named Frosty asked questions about intricate coding that later became part of the source code of Silk Road.

In another apparent slip-up, one of Frosty’s messages initially identified itself as being written by Ross Ulbricht – before being quickly corrected.

“I believe that Ulbricht changed his username to ‘frosty’ in order to conceal his association with the message he had posted one minute before,” lead prosecutor Christopher Tarbell wrote in court documents.

“The posting was accessible to anyone on the internet and implicated him in operating a Tor hidden service.”

HOW BITCOINS WORK

Bitcoin is often referred to as a new kind of currency.

But it may be better to think of its units as being virtual tokens that have value because enough people believe they do and there is a finite number of them.

Each bitcoin is represented by a unique online registration number.

These numbers are created through a process called “mining”, which involves a computer solving a difficult mathematical problem with a 64-digit solution.

Each time a problem is solved the computer’s owner is rewarded with bitcoins.

To receive a bitcoin, a user must also have a Bitcoin address – a randomly generated string of 27 to 34 letters and numbers – which acts as a kind of virtual postbox to and from which the bitcoins are sent.

Since there is no registry of these addresses, people can use them to protect their anonymity when making a transaction.

These addresses are in turn stored in Bitcoin wallets, which are used to manage savings. They operate like privately run bank accounts – with the proviso that if the data is lost, so are the bitcoins contained.

Price drop

News of the closure was followed by a rapid drop in the price of bitcoins, according to figures from the Mt. Gox bitcoin exchange.

The going rate for the virtual currency dropped from more than $140 (£86) to around $110, before climbing back up to $123 (£75).

Investors may have been concerned about the FBI’s ability to confiscate bitcoins, said Mr Ferguson.

“Knowing that a currency could be seized or shut down could pressure people to look for alternative investment vehicles,” he said.

The FBI seized the virtual currency by getting hold of encryption keys for the bitcoins, according to Jerry Brito, George Mason University’s technology policy director.

The keys were made available through seized computer equipment, Mr Brito said in a blog post.

The FBI then transferred the bitcoins to an address controlled by the US government, according to the seizure order.

Adobe information stolen in cyber attack on website

News has emerged that software giant Adobe information stolen in cyber attack on website

Adobe has confirmed that 2.9 million customers have had private information stolen during a “sophisticated” cyber attack on its website.

The attackers accessed encrypted customer passwords and payment card numbers, the company said.

But it does not believe decrypted debit or credit card data was removed.

Adobe Icons

Adobe also revealed that it was investigating the “illegal access” of source code for numerous products, including Adobe Acrobat and ColdFusion.

“We deeply regret that this incident occurred,” said Brad Arkin, Adobe’s chief security officer.

“Based on our findings to date, we are not aware of any specific increased risk to customers as a result of this incident,” he said.

But Chester Wisniewski, senior adviser at internet security company Sophos, told the BBC: “Access to the source code could be very serious.

“Billions of computers around the world use Adobe software, so if hackers manage to embed malicious code in official-looking software updates they could potentially take control of millions of machines.

“This is on the same level as a Microsoft security breach,” he added.

Adobe said it had been helped in its investigation by internet security journalist Brian Krebs and security expert Alex Holden.

The two discovered a 40GB cache of Adobe source code while investigating attacks on three US data providers, Dun & Bradstreet, Kroll Background America, and LexisNexis.

Mr Krebs said the Adobe code was on a server he believed the hackers used.

Compromised

Adobe said that it is resetting passwords for the customer accounts it believes were compromised, and that those customers will get an email alerting them to the change.

It is also recommending that, as a precaution, customers affected change their passwords and user information for other websites for which they used the same ID.

For those customers whose debit or credit card information is suspected of being accessed, Adobe is offering a complimentary one-year subscription to a credit-monitoring programme.

Finally, the company said it had notified law enforcement officials and is working to identify the hackers.

Royal Baby Malware Attacks

Scammers wasted little time after Prince William and his wife, the former Kate Middleton, announced the birth of their son, who’s now third in line to the British royal throne.

Royal Baby

“Because it is such big news, it didn’t take long for malicious elements to misuse it,” said Kaspersky Lab security researcher Michael Molsner in a Wednesday blog post, noting that the company’s spam traps had already intercepted an email promising regular “Royal Baby” updates.

The message also included a “watch the hospital-cam” link, which appeared to resolve to a legitimate site that had been compromised.

Although the site appears to have since been cleaned, it was serving malicious JavaScript files designed to infect browsers with the Blackhole infection kit.

Irish Cookie Regulations – Update

This article was writted by Philip Nolan, Head of Commercial Law Department and Partner MH & C and Oisin Tobin, trainee, MH & C. Philip Nolan is a Partner in the Commercial Contracts and Outsourcing Department at Mason Hayes & Curran.

kimberley biscuits cookies

The Irish Regulations transposing the new European rules on cookies have come into force. While website operators will need to exercise care to ensure that they are complying with the new regime, these new rules are less onerous and disruptive than originally anticipated.

Cookies, or small items of code placed on a user’s computer by a website, are vital to the functioning of the modern web. Cookies allow website operators to determine how users browse their sites and are a technical prerequisite for the operation of more advanced websites, such as those which require their users to log-in. Cookies can also be used, more controversially, to monitor user behavior for the purpose of targeting advertisements.

The rules governing cookies are being overhauled across Europe at present due to an EU Directive adopted in 2009. While all Member States are obliged to implement the Directive, they are given a certain degree of freedom as to the exact manner in which they chose to do so. The Irish measures which implement the Directive, and which have just come into force, seem to minimize the potential negative impact of the Directive for websites and web businesses based in Ireland.  As a result, it would seem that the new Irish regime may prove to be an additional attraction to international web based businesses considering Ireland as their EU base.

Under the new regime, all websites must have user consent before they place a cookie onto the user’s computer.  The Irish rules do not require that this consent be explicit and therefore, it would seem that consent may be implied.  In addition, they must provide the user with clear, comprehensive, prominently displayed and easily accessible information about the cookie, particularly as to its purpose. While this regime is somewhat tougher than the previous rules, which required that websites give a user the ability to “opt-out” of the cookie being used, these new rules contain a number of provisions which should ensure that websites can become compliant without having to radically overhaul their design.  The regulations note that the methods of providing information and giving consent should be as user friendly as possible. In certain circumstances users may be able to give consent via their browser settings and many consider that the use of browser settings for consent may become a popular means of managing consents. Cookies which are technically required to operate the site are exempt from these new rules.

Notably, a provision in an earlier draft of the Irish regulations, prohibiting the current practice of providing the relevant disclosures about cookie use in a privacy policy, has not made it into the final regulations.   This means that privacy policies may continue to be used, once user friendly and prominently displayed, to provide information about cookies in compliance with the new rules.

In summary, it would seem the Minister for Communications has struck quite an effective balance between the privacy concerns of web users in relation to the use of cookies and the concerns of industry in relation to over-regulation of the internet.

American FBI and Microsoft shut down the €375m theft botnet known as Citadel

The American FBI and Microsoft have cooperated in order to break up a massive network of hijacked home computers that have been responsible for stealing more than €375m from bank accounts around the globe.

The Citadel network was set up by a group of criminal gangs who remotely installed a keylogging program on upwards of five million machines in order to steal data.

About 1,000 of the 1,400 or so networks that made up the Citadel botnet are believed to have been shut down.

Co-ordinated action in 80 countries by police forces, tech firms and banking bodies helped to disrupt the network.

“The bad guys will feel the punch in the gut,” Richard Boscovich, a spokesman for Microsoft’s digital crimes unit said.

Control code

The cybercriminals behind Citadel cashed in by using login and password details for online bank accounts stolen from compromised computers.

This method was used to steal cash from a huge number of banks including American Express, Bank of America, PayPal, HSBC, Royal Bank of Canada and Wells Fargo.

Citadel emerged after core computer code for a widely used cybercrime kit, called Zeus, was released online.

Underground coders banded together to turn that code into a separate cybercrime toolkit that quickly proved popular with many malicious hackers.

In a blogpost detailing its action, Microsoft said Citadel had also grown because malicious code that could take over a PC had been bundled in with pirated versions of Windows.

The millions of PCs in the criminal network were spread around the globe, but were most heavily concentrated in North America, Western Europe, Hong Kong, India and Australia.

Despite the widespread action, which involved seizures of servers that co-ordinated the running of Citadel, the identity of the botnet’s main controller is unknown.

However, Microsoft has started a “John Doe” lawsuit against the anonymous controller, believing him to use the nickname Aquabox and be based in Eastern Europe.

In addition, the FBI is working with Europol and police forces in many other countries to track down and identify the 81 “lieutenants” that helped Aquabox keep Citadel running.

Microsoft has also started action to help people clean up an infected computer.

Typically, it said, machines compromised by Citadel were blocked from getting security updates to ensure those computers stayed part of the botnet.

With the network disrupted, machines should be free to get updates and purge the Citadel malware from their system.

We only work with advertising partners who work to accepted privacy standards such as http://www.youronlinechoices.com/uk/iab-good-practice-principles

You can learn more about online advertising at http://www.youronlinechoices.com. You can opt-out of almost all advertising cookies at http://www.youronlinechoices.com/uk/your-ad-choices although we would prefer that you didn’ as ultimately adverts help keep much of the internet free. It is also worth noting that opting out of advertising cookies will not mean you won’t see adverts, just simply that they won’t be tailored to you any longer.

We use:

  • DoubleClick – owned by Google

Banner Adverts

We fund our site by showing adverts as you browse our site. These adverts are usually managed by a partner specialising in providing adverts for multiple sites. Invariably these partners place cookies to collect anonymous data about the websites you visits so they can personalise the adverts to you, ensure that you don’t see the same adverts too frequently and ultimately report to advertisers on which adverts are working. Our partners include:

Remarketing Cookies

You may notice that sometimes after visiting a site you see increased numbers of adverts from the site you visited. This is because advertisers, including ourselves pay for these adverts. The technology to do this is made possible by cookies and as such we may place a so called “remarketing cookieâ€? during your visit. We use these adverts to offer special offers etc to encourage you to come back to our site. Don’t worry we are unable to proactively reach out to you as the whole process is entirely anonymised. You can opt out of these cookies at anytime as explained above.

Turning Cookies Off

You can usually switch cookies off by adjusting your browser settings to stop it from accepting cookies (Learn how here). Doing so however will likely limit the functionality of our’s and a large proportion of the world’s websites as cookies are a standard part of most modern websites
