More than 3.000 email servers remain at risk in the UK due to Microsoft Exchange failure
Britain's National Security Center estimates that 7.000 servers were affected by the Microsoft Exchange bug in the UK, and only half had already been secured. They reported that malware was detected on 2.300 machines, but it helped them businesses to remove it. The announcement reveals for the first time the scale of the problem in British companies, since the appearance of the global attacks last week.
Ransomware teams have begun using the flaw to install their malware, the NCSC has warned, although so far there have been no signs of widespread ransomware attacks on UK companies.
Once installed, ransomware locks a user's data with strong encryption, making it system of the computer useless. The team then demands payment to unlock them and if their requirements are not met, they will steal or delete the data.
