The Week in Ransomware – June 3rd 2022 – Evading sanctions
Ransomware gangs continue to evolve their operations as victims refuse to pay ransoms due to sanctions or other reasons.

Ransomware gangs continue to evolve their operations as victims refuse to pay ransoms due to sanctions or other reasons.

This is illustrated by Evil Corp no longer rebranding their Hades ransomware for attacks and instead using LockBit to evade sanctions by the US government.

The newer Industrial Spy group also began applying greater pressure on victims by hacking their websites to display ransom notes.

New intelligence continues to come from the Conti Leaks, with researchers revealing that the ransomware gang was working on exploits for the Intel Management Engine to plant bootkits and malicious firmware.

Finally, we saw increased attacks this month, with the Clop gang revealing new victims, Foxconn confirming our report of a LockBit ransomware attack in May 2021, and Costa Rica now being targeted by the Hive ransomware.

The Hive affiliate behind the Costa Rica attack is believed to be the same person currently posting on the Conti data leak site.
