Description(Trend Micro) Nefilim is among the notable ransomware variants that use double extortion tactics in their campaigns. First discovered in March 2020, Nefilim threatens to release victims’ stolen data to coerce them into paying the ransom. Aside from its use of this tactic, another notable characteristic of Nefilim is its similarity to Nemty; in fact, it is believed to be an evolved version of the older ransomware.
