ESET researchers have identified multiple samples of Linux backdoor, which we have named WolfsBane, that we attribute with high confidence to the Gelsemium advanced persistent threat (APT) group. This China-aligned threat actor has a known history dating back to 2014 and until now, there have been no public reports of Gelsemium using Linux malware. Additionally, we discovered another Linux backdoor, which we named FireWood. However, we cannot definitively link FireWood to other Gelsemium tools, and…

UPDATE (December 2nd, 2024): The bootkit described in this report seems to be part of a project created by cybersecurity students participating in Korea’s Best of the Best (BoB) training program. As they informed us: “The primary aim of this project is to raise awareness within the security community about potential risks and to encourage proactive measures to prevent similar threats. Unfortunately, few bootkit samples were disclosed prior to the planned conference presentation.” This supports…
