Internet users hit by ransom email spam
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.
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.
