SystemBC Powers REM Proxy, Compromising ~1,500 VPS

🛡️ Lumen Technologies' Black Lotus Labs reports that SystemBC, a C-based SOCKS5 proxy malware, powers roughly 80% of the REM Proxy network and averages about 1,500 compromised hosts per day. The botnet operates through more than 80 C2 servers and mainly targets VPS instances from major commercial providers, often via dropped shell scripts that install the proxy implant. REM Proxy also advertises pools of compromised Mikrotik routers and open proxies and has been used by actors tied to TransferLoader and the Morpheus ransomware group.

Gamaredon and Turla Collaborate in Attacks on Ukraine

🕵️ ESET researchers report that Russian state-linked groups Gamaredon and Turla collaborated in 2025 campaigns targeting high-value Ukrainian defense systems. In February, investigators observed Turla issuing commands via Gamaredon implants and Gamaredon's PteroGraphin downloader being used to restart Turla's Kazuar backdoor. Kazuar harvested machine metadata while Gamaredon later deployed Kazuar v2 installers in April and June. ESET assesses with high confidence that the interactions reflect a deliberate operational convergence.

Ransomware Extortion Claim Targets BMW Group Servers

🔒 The BMW Group has been named on the darknet by the Everest ransomware group, which claims to have stolen critical BMW audit documents, according to screenshots reported by Cybernews. The gang placed two countdown timers on its onion site—one running to Sept. 14 and a second giving BMW 48 hours to make contact. BMW has not commented and the extortionists have not confirmed whether customer or personal data were taken; Cybernews researcher Aras Nazarovas advises waiting for a published sample to assess the scope.

Gamaredon and Turla Collaborate to Deploy Kazuar Backdoor

🔒ESET researchers observed tools from Russian-linked groups Gamaredon and Turla cooperating to deploy the .NET-based Kazuar backdoor on multiple Ukrainian endpoints in early 2025. Gamaredon delivered PowerShell downloaders — PteroGraphin, PteroOdd and PteroPaste — which retrieved Kazuar payloads via Telegraph, Cloudflare Workers domains and direct IP hosting. Analysts assess with high confidence that Gamaredon provided initial access while Turla leveraged the access for espionage, primarily targeting Ukrainian defense-sector assets.

HybridPetya ransomware bypasses Windows Secure Boot

🔒 Researchers at ESET have identified a new bootkit-style ransomware named HybridPetya that targets the NTFS Master File Table (MFT) and can override UEFI Secure Boot to install a malicious EFI component. The malware abuses a patched vulnerability (CVE-2024-7344) in a signed Microsoft EFI file to load an unsigned payload called cloak.dat. The installer replaces the Windows bootloader, triggers a crash and, on reboot, the compromised loader executes a bootkit that encrypts the disk with Salsa20, using a fake CHKDSK message to conceal activity. ESET observed a ransom demand of €850 in Bitcoin but regards the sample as likely a research proof-of-concept.

SonicWall Urges Password Resets After Backup Files Exposure

🔒 SonicWall is urging customers to reset credentials after detecting suspicious activity that exposed firewall configuration backup files stored in MySonicWall cloud for under 5% of users. Although stored credentials were encrypted, the preference files contained information that could help attackers exploit related firewalls; the company says this was a series of brute-force accesses, not a ransomware event. Customers should verify backups, disable remote management and VPN access, reset passwords and TOTPs, review logs, and import the provided randomized preferences file that resets local passwords, TOTP bindings, and IPSec keys.

PyPI Invalidates Tokens Stolen in GhostAction Attack

🔐 The Python Software Foundation has invalidated PyPI publishing tokens that were exfiltrated during the early-September GhostAction supply chain attack. GitGuardian first reported malicious GitHub Actions workflows attempting to steal secrets, and PyPI found no evidence that the stolen tokens were used to publish malware. Affected maintainers were contacted and advised to rotate credentials and adopt short-lived Trusted Publishers tokens for GitHub Actions. PyPI also recommended reviewing account security history for suspicious activity.
