Hacking gangs Killnet, Anonymous Sudan and REvil are threatening to launch a “destructive” attack against the whole of the European financial system, starting with the SWIFT international communications system, at some point in the next 48 hours. In a video released yesterday the trio say they are hitting back at Europe for its role helping Ukraine in the war with Russia. Security researchers have told Tech Monitor that while this prospect may appear far-fetched, financial institutions they should be on "high alert" for some kind of an attack, as KillNet is known for its powerful distributed denial of service (DDoS) attacks.

The attacks may very well be sanctioned by the Russian government, as all three gangs have been linked to security service the GRU in the past.
