The cyber-criminals responsible for causing major disruption at London hospitals say they are 鈥渟orry" for all the harm caused but are 鈥渘ot to blame鈥�.

The ransomware gang spoke to the 蘑菇短视频 on encrypted chat service qTox attempting to justify the attack as a form of political protest.

Qilin, which has a well established record of attempting to extort money, claims in this instance it carried out a cyber-attack as revenge for the UK government鈥檚 actions in an undisclosed war.

Experts are sceptical, however, with Jen Ellis, from the organisation Ransomware Task Force, telling the 蘑菇短视频 that "cyber-criminals like this gang lie routinely."
