Security News > 2023 > September > Evasive Gelsemium hackers spotted in attack against Asian govt
A stealthy advanced persistent threat tracked as Gelsemium was observed in attacks targeting a Southeast Asian government that spanned six months between 2022 and 2023.
Gelsemium is a cyberespionage group operational since 2014, targeting government, education, and electronic manufacturers in East Asia and the Middle East.
A new report by Palo Alto Network's Unit 42 reveals how a new Gelsemium campaign uses rarely seen backdoors linked to the threat actors with medium confidence.
The OwlProxy is a unique, custom HTTP proxy and backdoor tool Unit 42 reports Gelsemium used in a past attack targeting the Taiwanese government.
The second custom implant associated with Gelsemium is SessionManager, an IIS backdoor that Kaspersky linked to the threat group last summer.
In conclusion, Unit 42 notes Gelsemium's tenacity, with the threat actors introducing multiple tools and adapting the attack as needed even after security solutions stopped some of their backdoors.
