OverviewA new Linux toolkit, identified by Rapid7 Labs, has been targeting organizations across South Korea’s automotive and media industries with minimal detection. The campaign made use of a HAProxy instance named “ted backdoor”, alongside trojanized versions of crond, agetty, atd, sshd, and polkitd. This previously undocumented framework enabled threat actors to execute remote commands on compromised servers, inject malicious scripts into web traffic, perform credential harvesting, and…
Introduction We continue tracking the activity of Toy Ghouls (also known as Bearlyfy, Laboo.boo, and Feral Wolf), a financially motivated group that has been targeting Russian organizations since 2025. The attackers initially relied exclusively on tools pulled from public GitHub repositories along with leaked Babuk and LockBit ransomware builders, later shifting to their own custom ransomware, GenieLocker. In early July 2026, we observed the group using a custom backdoor for the first time. We…

“Free” movies and TV could cost you your privacy, bandwidth, and control of your home network. We’ve warned about illegal streaming and modded Amazon Fire TV Sticks in the past. Now, researchers have found that certain SuperBox devices and apps could quietly enroll a household connection into a proxy network, allowing third parties to route traffic through it. An earlier report identified CyberFlix TV, available through SuperBox’s custom app store, as containing Popanet proxy functionality that…

Fileless execution on Linux has moved from niche tradecraft into real-world intrusion chains. By executing payloads from memory or anonymous file descriptors, attackers can reduce on-disk artifacts and weaken controls that rely heavily on file inspection.In our own analysis of VoidLink, we observed how fileless execution can be paired with a rootkit. The loader scans for processes running from memfd and passes their PIDs to the rootkit, allowing an already running fileless implant to be hidden…

The attackers may have chosen this distribution method because the adware was signed by the developer. On top of that,…
