Security News > 2023 > September > Alert: Phishing Campaigns Deliver New SideTwist Backdoor and Agent Tesla Variant
The Iranian threat actor tracked as APT34 has been linked to a new phishing attack that leads to the deployment of a variant of a backdoor called SideTwist.
"APT34 has a high level of attack technology, can design different intrusion methods for different types of targets, and has supply chain attack capability," NSFOCUS Security Labs said in a report published last week.
The payload is a variant of SideTwist that's compiled using GCC and establishes communication with a remote server to receive further commands.
The development comes as Fortinet FortiGuard Labs captured a phishing campaign that spreads a new Agent Tesla variant using a specially crafted Microsoft Excel document that exploits CVE-2017-11882, a six-year-old memory corruption vulnerability in Microsoft Office's Equation Editor, and CVE-2018-0802.
"The Agent Tesla core module collects sensitive information from the victim's device," security researcher Xiaopeng Zhang said.
It also follows the discovery of another phishing attack that has been found to employ ISO image file lures to launch malware strains such as Agent Tesla, LimeRAT, and Remcos RAT on infected hosts.
