Magniber, a ransomware sample that’s most likely a successor to the nasty Cerber culprit, undergoes an update within one of the multiple affiliate campaigns. The infection switches to subjoining the .skvtb extension to ransomed files.
It’s time for Jigsaw to get some fine-tuning
Cybercriminals release a new variant of the Jigsaw ransomware, a true old stager on the extortion arena. The pest now appends the .game suffix to victims’ data entries while still displaying the same movie-themed (Read more...)
