Multiple statements emanated from the White House yesterday regarding evolving intelligence that the Russian government is exploring options for potential cyber attacks and that preparatory actions have been observed against U.S. critical infrastructure. WaterISAC posted and distributed an advisory, Update from the White House – Act Now to Protect Against Potential Cyber Attacks, shortly after the initial White House release.
The cybercriminal group Lapsus$ claims to have successfully compromised Microsoft’s internal Azure DevOps server and stolen source code for Bing, Cortana virtual assistant, and other projects. Yesterday, the threat actors leaked around 40 Gb of data stolen from Microsoft and claimed to have targeted LGE corporation and identity and access management company Okta. Lapsus$ is a data extortion cyber group that compromises business networks to steal source code, customer lists, databases, and other valuable data.
The infamous malware botnet Emotet continues to resurge and propagate through persistent scams. Recently, Emotet was observed in a campaign leveraging tax season themed lures and impersonating the IRS to trick victims into downloading the malicious botnet. In these new campaigns, Emotet threat actors send out supposed “tax documents” for recipients to view or fill out and return to the sender.
The FBI and the Department of the Treasury released a joint Cybersecurity Advisory (CSA) detailing indicators of compromise associated with AvosLocker ransomware. AvosLocker operates as a Ransomware-as-a-Service (RaaS) affiliate-based group and has targeted several critical infrastructure sectors in the U.S. and across the world, including government facilities.
For several months the White House, Cybersecurity and Infrastructure Security Agency (CISA), and other federal partners have been warning all U.S. organizations to be prepared for the potential for Russian state-sponsored cyber activity against our businesses and national critical infrastructure. The preparedness guidance has been informed by historical activity and incidents from Russian adversaries and issued out of an abundance of caution, until now.
Security researchers have identified a new Ransomware-as-a-Service (Raas) family dubbed LokiLocker that has been active in the wild since August 2021. The ransomware employs file encryption to extort its victims and data wiping capabilities that can make an infected device unusable if a victim fails to pay the ransom. To obfuscate its activities, LokiLocker displays a fake Windows Update screen and disables multiple Windows security applications. It also deletes backup files and shadow copies to prevent data recovery.
