Liquid Hackers Return 3,400 Bitcoin Taken via Elements Bug, Still Holding $47M in BTC

Hackers exploited an Elements bug to take ~4,000 BTC from Liquid Network, returned 3,400 BTC (~$265M), and still hold ~598.5 BTC (~$47M).

Attackers exploited a bug in Elements, the software behind Blockstream's Liquid Network Bitcoin sidechain, to create L-BTC and withdraw roughly 4,000 BTC (about $320 million) via SideSwap's Peg-out Authorization Key, roughly 95% of Liquid's reported reserves. They returned 3,400 BTC (about $265 million at ~$78,000 per BTC) to the federation address on September 7, keeping about 598.5 BTC (roughly $47 million). The group called itself white hats, demanded node patches before returning funds, and negotiated via on-chain and PGP-encrypted messages; Ledger CTO Charles Guillemet characterized the arrangement as extortion. Blockstream says the peg-out key and other keys were not compromised, updated software is deployed, and the network remains paused pending a coordinated restart.

Critical Gitea RCE Actively Exploited as Reported Attack Drops Miner

CISA added actively exploited Gitea RCE CVE-2026-60004 (CVSS 9.8) to the KEV catalog as attackers deploy a cryptojacking dropper.

CVE-2026-60004 is a critical remote code execution flaw affecting Gitea versions 1.17 through 1.27.0, abused via the diffpatch endpoint to install a Git hook and execute shell commands as the Gitea OS user. Default open registration lets unauthenticated attackers obtain the required repository write access. CISA added the flaw to its Known Exploited Vulnerabilities catalog, giving federal agencies until August 28, 2026 to patch; version 1.27.1 fixes it. A developer reported their HOSTKEY-hosted VPS was exploited to run a miner-like dropper, driving CPU usage above 70% and killing competing processes.

BGP Hijack Delivers Malicious Virtualizor Update That Establishes Persistent Root Access

Attackers used a BGP hijack to divert Softaculous traffic and push a malicious Virtualizor update granting root persistence on some hypervisors.

Virtualizor reported that a BGP hijack between August 28 20:57 UTC and August 30 06:10 UTC diverted Softaculous update traffic to an attacker-operated server holding a valid Let's Encrypt certificate. Installations checking for updates during the window could receive a malicious package that added an attacker SSH key to root, created a proxyuser account, and installed a Java payload persisted via a systemd service. Hosting provider AlbaHost confirmed 5 of its 34 Virtualizor hypervisors were root-compromised. Virtualizor shipped Patch 9 with a Security Analyzer on September 1, but cryptographic package signing remains future work.

Cisco FMC flaws exploited by ransomware gang, state-sponsored hackers

Cisco Talos confirms ransomware and state-sponsored groups exploited CVE-2026-20079 and CVE-2026-20316 in Secure Firewall Management Center, deploying Qilin ransomware and Cyclops Blink.

Cisco Talos identified three threat clusters (UAT-12197, UAT-11823, UAT-11988) exploiting CVE-2026-20079, a CVSS 10.0 authentication bypass, and CVE-2026-20316, a CVSS 5.3 static-credential flaw, in Cisco Secure Firewall Management Center. Qilin affiliates used static credentials for reconnaissance and deployed Qilin ransomware; a Sandworm-linked cluster deployed a Cyclops Blink backdoor via a malicious license.tmp file; a third cluster stole credentials through a JSP web shell. Cisco has released hotfixes and urges immediate installation, with broader patches expected next week.

Hackers Exploit FortiGate SSL-VPN Flaw to Breach Thai ISP and Deploy MeshCentral Backdoor

Threat actors exploited FortiOS SSL-VPN flaw CVE-2024-21762 to breach Thai ISP Triple T Broadband, gaining root-level persistence via MeshCentral agents.

Attackers exploited CVE-2024-21762, an out-of-bounds write enabling unauthenticated RCE in FortiOS SSL-VPN, against Triple T Broadband's FortiGate 60F at mail.3bb.co.th, launching a Node.js reverse shell via a ROP payload. Hunt.io uncovered the operation through an exposed staging directory at 92.63.180[.]133:8888 containing 298 files of exploits, credential-harvesting scripts, session cookies, and a device inventory. Post-compromise, the actors deployed MeshCentral agents (device group TH-3BB, C2 www.ayuthayatech.com) running as root, plus a hidden SUID backdoor at /usr/local/bin/.rc, and also targeted an internal Pentaho/Tomcat server with Ghostcat (CVE-2020-1938). A cleanup script removed logs, shell histories, and web shells while deliberately preserving the MeshCentral agent and SUID backdoor.

Attackers exploit patched macOS Screen Sharing flaw to deploy cryptominer

Attackers actively exploit patched macOS Screen Sharing bug CVE-2026-65400 on systems with port 5900 exposed, gaining root to install a Monero cryptominer.

The Netherlands' National Cyber Security Centre (NCSC) reports active exploitation of CVE-2026-65400, an authentication flaw in macOS Screen Sharing that lets attackers authenticate without valid login credentials. Apple patched the issue in macOS Sequoia 15.7.9, Sonoma 14.8.9 and Tahoe 26.6.1, and the NCSC escalated its advisory on August 12 after proof-of-concept code went public and reports arrived of attacks on internet-exposed systems. In every reported case attackers obtained root access and installed a Monero crypto miner; users who cannot patch immediately are advised to disable Screen Sharing.
