On Friday 12th of May the NHS and other organisations across the UK and Europe were hit by a massive virus attack that caused wide spread disruption to their computer systems. The virus was a type of ransomware that encrypted files and demanded payment before the files were released. This virus most likely spread through an email which had either an attachment or possibly a link to a compromised web site controlled by the hackers. That web site would have triggered a download when you clicked on it.
The authorities are expecting a second wave of attacks to happen on Monday 15th of May. It is essential that you and your staff are especially vigilant at this time.
IF you receive an email and you are unsure of its authenticity DO NOT OPEN IT – DELETE IT.
A widely distributed scam email that quotes peoples’ postal addresses links to a dangerous form of ransomware, according to a security researcher.
The emails link to a ransomware called Maktub.
The malware encrypts victims’ files and demands a ransom be paid before they can be unlocked.
The phishing emails told recipients they owed hundreds of pounds to UK businesses and that they could print an invoice by clicking on a link – but that leads to malware.
It’s incredibly fast and by the time the warning message has appeared on the screen it has already encrypted everything of value on the hard drive – it happens in seconds.
