REvil, a notorious ransomware gang, has been resurrected after it was supposedly squashed by Russian authorities back in July.

REvil websites disappeared from the internet in mid-July after President Joe Biden pressured his Russian counterpart, Vladimir Putin, to shut down the Russian-speaking ransomware group. REvil had previously gone dark for several months in late 2021 and early 2022 after a major ransomware attack on information technology management software provider Kaseya.
