How does that old expression go? If you can’t beat them, join them? Although perhaps the best outcome is when you can beat them by joining them. That’s what one unnamed white-hat hacker did in the case of the Dridex online banking Trojan virus. Unsuspecting victims of that nasty piece of malware have found themselves with a brand new anti-virus install instead of having their banking details stolen.

Dridex is a Trojan that’s been commonplace in email inboxes for the past few years and is one of the top three pieces of phishing malware in terms of utilization. Authorities have been looking to shut it down for some time and in 2015 even managed to catch someone who may be responsible for it — but the Trojan is still out there, causing damage.

Except it’s doing a lot less of it now, as whoever was behind the white-hat hack was able to crack into the Dridex distribution servers and replace the malicious files with a full installer of the latest version of Avira anti-virus. Now when some are infected, instead of having their keystrokes recorded and their banking searches injected with malicious code, they get an anti-virus install.

Of course there is still a chance that this is all a ruse. Avira isn’t behind the move, so some have suggested that the files being sent out are still malicious in nature, but are at this time just attempting to trick people into trusting Avira or being less careful with what they install.

“We still don’t know exactly who is doing this with our installer and why, but we have some theories,” said Moritz Kroll, a malware expert at Avira (via PCWorld). “This is certainly not something we are doing ourselves.”

If this is the case of a white-hat hacker doing a good deed though, it’s difficult not to wish them well. In the world of anti-cyber-crime, we need all the help we can get.

Hackers can now sneak malware into the GIFs you share
A video call in progress on Microsoft Teams.

The new attack is called GIFShell and it installs malware on your computer to steal data. It does so by sneaking itself into innocent-looking GIFs and then waiting for you to share the GIF with your colleagues via Microsoft Teams.
