An advanced persistent threat group with links to Iran has updated its malware toolset to include a novel PowerShell-based implant called PowerLess Backdoor, according to new research published by Cybereason. The Boston-headquartered cybersecurity company attributed the malware to a hacking group known as Charming Kitten, while also calling out the backdoor's evasive PowerShell execution.

Cybersecurity researchers on Monday said they uncovered evidence of attempted attacks by a Russia-linked hacking operation targeting a Ukrainian entity in July 2021. Broadcom-owned Symantec, in a new report published Monday, attributed the attacks to an actor tracked as Gamaredon, a cyber-espionage collective known to be active since at least 2013.

Details have emerged about a previously undocumented malware campaign undertaken by the Iranian MuddyWater advanced persistent threat group targeting Turkish private organizations and governmental institutions. "This campaign utilizes malicious PDFs, XLS files and Windows executables to deploy malicious PowerShell-based downloaders acting as initial footholds into the target's enterprise," Cisco Talos researchers Asheer Malhotra and Vitor Ventura said in a newly published report.
