Kremez said that network administrators need to now “scan for unauthorized Atera Agent installations and Any Desk persistence.”
“The #Conti adversaries put in legit @AteraCloud RMM agent w/ a single-day burner accounts to survive Cobalt Strike detects,” he included.
One more security researcher, going by the name of pancak3, stated in a tweet that corporations should block many IP addresses to stay clear of the group’s attacks. These IP addresses were being disclosed in the leaked details.

“Groups these kinds of as this also leverage non-public chat channels permitting for troubleshooting with actors who may perhaps be additional competent or knowledgeable. This isn’t special to these actors though,” she said.
“We’ve witnessed other groups function similarly, in the end enabling a increased amount of actors to master how to perform these attacks. A person potential advantage of this leak is that the documentation is now accessible to defenders who may perhaps have not earlier seen these methods used towards them and now can assessment the documentation to probably allow far better defenses.”
