I noticed that there was no thread in this Forum for the Retefe Banking Trojan, so I created one.

There's an ongoing spam campaign targeting Swiss users which sends Word Documents with embedded LNK files to spread Retefe.

It looks like the new variants of Retefe Banking Trojans are not using the Eternal Blue Exploit once again. Maybe, there are plans to update the exploit or add a new variant? :)
