New TELESHIM campaign abuses Telegram for C2

🛡️ Zscaler ThreatLabz has detected an East Asia–linked campaign targeting Middle Eastern government entities that deploys three previously unreported malware families: TELESHIM, MIXEDKEY, and BINDCLOAK. The attack begins with an ISO that sideloads a rogue DLL to run a 32‑bit backdoor (TELESHIM) which uses the Telegram API for command-and-control, then stages additional payloads via DLL side‑loading and a reflective loader (MIXEDKEY). TELESHIM and MIXEDKEY employ heavy obfuscation and anti-analysis checks, while the final 64‑bit implant BINDCLOAK communicates with an external C2 server; observed activity occurred between July 7–9, 2026.

Steam forum ClickFix attacks deliver XMRig miners

🛡️ Threat actors are abusing Steam discussion forums with ClickFix social engineering posts that instruct users to run PowerShell commands purportedly to fix game or system issues. The commands download and run an XMRig cryptominer disguised as a Windows optimization utility named msf utility \ PC Opt, which fakes maintenance progress while installing a miner as C:\Windows\Background\system.exe and persisting via a scheduled task. Victims are advised to check for the Background folder, Defender exclusions, and scheduled tasks named 'XMRig-[computer name]' and to run antivirus scans or consider OS reinstall.

Malvertising builds malware in browser memory

🛡️ A widespread malvertising campaign uses fake Solana, Luno, and TradingView pages with malicious JavaScript that assembles malware directly in the browser's memory.

Confiant found the pages register service and shared workers to piece together a unique executable from remote components and local bytes, avoiding transmission of a finished file to evade detection.

GitLab RCE exploit published for unpatched instances

🛡️ Security researcher depthfirst published a working exploit on July 24 for a GitLab flaw patched by GitLab on June 10, enabling command execution as the git user on self-managed 18.11.3 servers that haven't updated. The chain abuses two memory-corruption bugs in the Oj Ruby JSON parser via GitLab's notebook diff renderer, allowing authenticated users who can push a project to leak a heap pointer and trigger a payload without admin or CI access. GitLab listed the Oj 3.17.3 bump under bug fixes rather than as a security fix, leaving operators unaware of the urgency; no CVE or CVSS score has been published yet.

TrickBot shifts to DNS tunneling for C2 communications

🛡️ Fortinet researchers uncovered a TrickBot variant that abandons HTTP for a custom DNS tunneling C2 channel, embedding encrypted commands and payloads within malformed DNS queries. The modular malware uses single-byte XOR encoding, hex-encoding and 63-character domain chunking for outbound beacons, while inbound data hides in multiple IPv4 addresses returned by resolvers. Persistence relies on Windows Task Scheduler with NTFS ADS, and command handling retains prior modular capabilities for executing modules, DLLs, PowerShell and shellcode.
