The hackers behind Troldesh, the world's largest ransomware virus, announced that 750,000 keys were made public.
Troldesh, on the other hand, is the most widespread ransomware virus in the world in recent years, accounting for 7% of ransomware incidents in 2017, with a significant increase in the number of detected attacks from 2018 to 2019, only no one has counted the number in detail, but it is undoubtedly one of the largest ransomware viruses in the world.
Troldesh virus spreads mainly through email attachments, once the victim opens and runs the java script in the ZIP attachment, it will be controlled by the virus software, important files will be encrypted, either pay money to decrypt, or abandon the file and reset the system too.
This hacking team is very mysterious, and it is known that the internal annotated documents are in English and Russian, and the common speculation in the foreign media is that it was produced by a Russian hacking team.
But these two days, the hacker team that created the Troldesh virus released a statement on Github that the virus had stopped spreading in 2019, and they decided to do one last thing - publish all the decryption keys the team had, totaling over 750,000.
The hacking team also apologized to the victims and hoped that the decryption keys released would help those victims recover their data.
As for the authenticity of decryption keys, Kaspersky has confirmed that decryption tools based on these keys are being issued.
