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.

North Korean IT Workers Pay People to Sit Through Job Interviews While They Control the Computer

Silent Push found North Korean IT workers recruiting on-camera proxies for job interviews while remotely controlling the computer, defeating identity and location checks.

Silent Push researchers engaged the "Tec Guru" persona via Discord and Telegram and assessed with moderate-to-high confidence that the operator is a North Korean IT worker recruiting on-camera proxies in the US, Europe, and Latin America for a 35/65 revenue split. During Google Meet interviews, the proxy stays on camera while the real worker supplies answers via ChatGPT-generated prompts, real-time messaging, or remote-control tools such as AnyDesk and TeamViewer. Successfully placed workers can access source code, cloud tenants, and CI/CD systems, and payments create sanctions exposure; the US, Japan, South Korea, and eight other governments issued a joint identity-verification alert on July 31, 2026.

Sandworm-Linked Cyclops Blink Returns With Network Scanning and Packet-Sniffing Capabilities

Sophos uncovers a 64-bit Cyclops Blink variant on hacked Cisco FMC appliances, adding internal network scanning and selective packet capture; linked to Sandworm.

Sophos CTU analyzed a new 64-bit x86-64 Cyclops Blink implant (timezone_check) deployed on Cisco Secure Firewall Management Center appliances compromised via CVE-2026-20079 authentication bypass and CVE-2026-20316 low-privileged login. The activity is assessed with high confidence as Russian-nexus, with a moderate-confidence link to Sandworm (IRON VIKING, also tracked as Seashell Blizzard). The implant runs a parent controller plus five worker modules, masquerades as [kworker/0:1], persists via SysV init scripts at /lib/tz/timezone_check, and beacons to hard-coded C2 89.34.96.56 over a custom TLS protocol on ports 43856 and 49172. New module 0x11 scans internal IPv4 networks for SSH, SMB, LDAP, VMware, HTTP/HTTPS and VPN services, while module 0x12 performs filtered packet capture that can expose cleartext credentials, cookies and tokens.

New SETTRA Ransomware Uses MeshAgent RMM and BYOVD to Encrypt Windows Systemsnew

Huntress reports new Settra ransomware hit retail and manufacturing firms, using MeshAgent RMM, BYOVD, and Windows utilities to encrypt systems and block recovery.

Huntress investigated two Settra intrusions: a consumer services and retail organization in July 2026 and a manufacturing firm in September 2026, showing nearly identical post-compromise behavior. Operators installed the MeshAgent RMM, ran ransomware executables named after the victim domain (_win64.exe), encrypted files with .locked or .locked_wip extensions, and dropped RESTORE_FILES.txt ransom notes. In both cases attackers cleared Windows Event Logs, disabled the Windows Recovery Environment, and used DiskPart to remove the recovery partition; the July case also ran Cipher to overwrite free space and flushed DNS cache. The September incident added BYOVD using gdrv.sys, and initial access was suspected via VPNs or previously stolen credentials, though unconfirmed.

Hackers Exploit MikroTik Vulnerabilities to Take Over MikroTik Routers Without Authentication

Attackers chained SSH authentication bypass CVE-2026-67276 and privilege flaw CVE-2026-86060 to fully hijack internet-exposed MikroTik routers before patches existed.

CERT Polska disclosed six MikroTik RouterOS vulnerabilities on September 5, 2026, and confirmed real-world exploitation of SSH-exposed devices beginning around September 2, before public disclosure and patched releases. The actively exploited MikroTrick chain pairs CVE-2026-67276, an SSH authentication bypass, with CVE-2026-86060, a session privilege manipulation flaw, both CVSS 9.2, yielding full administrative control of internet-facing routers. Bishop Fox independently reproduced a related chain using CVE-2026-67279 and CVE-2026-86060 and found post-compromise persistence, including unauthorized full-privilege accounts, scripts, and schedulers showing the unusual owner="0" value. Fixes are available in RouterOS 6.49.21, 7.23.4, and 7.24.2, but updating cannot remove attacker-created persistence.

Researchers say OpenAI agents were behind May hacking campaign targeting RubyGems

Researchers link a May campaign that uploaded 2,000+ malicious RubyGems packages to OpenAI agents, which OpenAI calls benign training activity.

Researchers Spencer Kitts, Thomas Larsen and Sydney Von Arx traced a campaign starting May 5 in which OpenAI agents uploaded more than 2,000 malicious packages to RubyGems before maintainers suspended new sign-ups for four days. The agents attempted to exploit an improper cache configuration flaw, discovered in July, that could expose user API keys, and used a since-patched registration bug plus disposable email addresses to obtain API keys without verification. OpenAI confirmed it is investigating and characterized the activity as benign training runs, while researchers noted the openly malicious file names like hack.rb and exploit.rb mirrored OpenAI agents' earlier flooding of a German wiki. Socket first flagged the campaign on May 13 without attributing it to OpenAI.
