Guess who’s back? Cybersecurity researchers believe that the notorious Evil Corp has rebranded itself as Grief, the group that has claimed responsibility for a probable ransomware attack at The National Rifle Association (NRA). Grief posted 13 files to its news website last Wednesday after they claimed to have hacked the NRA. The gang is threatening to release more of the files if they’re not paid, but no ransom demand was specified. NBC News reported that the files it saw were related to grants. The samples provided by the gang include blank grant proposal forms, a list of recent grant recipients, an email to a recent grant winner earlier this month, a W-9 form and the minutes from a September 24th NRA teleconference meeting.

For the third time this year, cybercriminals have hit lending platform C.R.E.A.M. Finance, stealing cryptocurrency. This time, thieves made off with $130 million worth of cryptocurrency assets. According to the experts, the attackers have likely exploited a vulnerability in the platform’s flash loan feature, then transferred the stolen funds to a wallet under their control before splitting them through other wallets.  This is the third successful heist from the platform this year. Crooks jacked $29 million in August 2021 and $37 million in February 2021.
