MikroTik Patches Critical Flaws Chained to Hack Routers

MikroTik patches six RouterOS flaws; two chained as MikroTrick are actively exploited via SSH to fully compromise exposed routers.

MikroTik released patches for six RouterOS vulnerabilities, including actively exploited MikroTrick chain: CVE-2026-67276 (9.2, SSH auth bypass) and CVE-2026-86060 (9.2, privilege manipulation), plus CVE-2026-67277 (8.8). CERT Poland confirms exploitation since September 2, creating an 'ops' account from IPs 82.192.72.4 and 103.102.31.18. Fixed in RouterOS 7.25beta3, 7.24.2, 7.23.4, and 6.49.21; Shadowserver found 120,000+ SSH-exposed MikroTik devices.

MikroTik router flaws allow takeover without a password

Attackers actively exploit chained MikroTik RouterOS SSH flaws CVE-2026-67276 and CVE-2026-86060, bypassing authentication and escalating to admin to seize edge routers.

CERT Polska warns of active exploitation of a two-flaw chain dubbed 'MikroTrick' against internet-exposed MikroTik RouterOS devices with SSH remote management enabled. CVE-2026-67276 is an SSH authentication bypass in RSA public-key handling, and CVE-2026-86060 is a privilege-escalation flaw triggered via a specially crafted username, letting attackers gain full administrator control without a password. Patched RouterOS packages are already public, and MikroTik added a startup detection that flags unauthorized configuration changes. Compromised edge routers enable DNS hijacking, traffic capture, remote-access tunnels, firewall changes, and lateral attacks.

Hackers Exploit FortiGate SSL-VPN Vulnerability to Attack Broadband Provider

Exposed attacker staging server reveals intrusion of Thai broadband provider 3BB via actively exploited FortiGate SSL-VPN flaw CVE-2024-21762.

Hunt.io found an open directory on server 92.63.180[.]133 holding 298 files detailing an intrusion into Triple T Broadband's 3BB brand, starting from a FortiGate 60F SSL-VPN at mail.3bb.co[.]th:10443. The actor weaponized CVE-2024-21762 (CVSS 9.8, KEV-listed since February 2024) using heap spraying and a ROP chain to gain a reverse shell. Post-exploitation included MeshCentral root-level persistence via www.ayuthayatech[.]com, Dirty COW/PwnKit privilege escalation, credential harvesting, SSH spraying against 55+ internal addresses, and log-deleting cleanup scripts; a stolen OpenVPN certificate and key from Triple T's PKI may still be valid.

Apple macOS Screen Sharing Flaw Exploited on Internet

Actively exploited CVE-2026-65400 in macOS Screen Sharing grants pre-auth root access; attackers deploy Monero miners on exposed systems.

NCSC-NL reported active exploitation of CVE-2026-65400 (CVSS 9.8), an authentication flaw in macOS Screen Sharing patched on August 6, 2026, with root access gained and a Monero miner planted on internet-exposed systems using port 5900. Related Screen Sharing bugs CVE-2026-43779, CVE-2026-43777, and CVE-2026-43760 were fixed in macOS Tahoe 26.6, and researcher @osxreverser noted a pre-auth flaw fixed alongside them affecting roughly 40,000 exposed hosts. Calif said an AI agent produced working exploits for both pre-auth bugs in four hours, underscoring the shrinking gap between patch release and weaponization.
