Small firms warned about mass malware campaign
The National Crime Agency’s (NCA’s) National Cyber Crime Unit (NCCU) has issued a warning about a new mass e-mail malware campaign. The e-mails, which are specifically targeted at smaller firms and consumers, appear to be from financial institutions, but carry a malicious attachment that encrypts files on the infected computer and any local network it is attached to. A £500 ransom demand in bitcoins is then made to unlock the files. The NCCU is urging firms not to open any suspicious-looking attachments, regularly back up files to a location off the network and update antivirus software. Anyone whose device is infected by this malware should report it via ActionFraud.
