NCSC Warns of Critical Check Point VPN Flaws as Large-Scale Exploitation Is Expected

Dutch NCSC warns of two critical CVSS 9.8 Check Point VPN flaws enabling unauthenticated remote code execution, urging immediate patching before mass exploitation.

The Dutch NCSC warned that CVE-2026-85102 and CVE-2026-85103, both rated 9.8 CVSS, allow unauthenticated remote attackers to execute arbitrary code on Check Point Quantum Security Gateway, Spark Firewall, and Security Management Server deployments when VPN is enabled. CVE-2026-85102 stems from improper certificate trust validation during VPN negotiation, while CVE-2026-85103 is a heap-based buffer overflow in ASN.1 certificate decoding. Check Point shipped emergency updates on September 9, 2026, including R82.10 Take 44, R82 Take 126, and R81.20 Take 166 or later, plus LivePatch for eligible systems. No public exploit code exists yet, but the NCSC rates exploitation likelihood high and recommends restricting UDP ports 500 and 4500 to known peers as a stopgap.

3BB Attacker Used MeshCentral Backdoor for Root Access, Targeted Subscriber Credentials

Hunt.io found an attacker holding root access inside Thai ISP 3BB via a MeshCentral backdoor, targeting subscriber RADIUS credential databases.

Hunt.io discovered an exposed attacker server on June 3, 2026 revealing an ongoing intrusion at 3BB, one of Thailand's largest broadband providers. The attacker maintained hidden MeshCentral agents reporting to www.ayuthayatech[.]com (device group TH-3BB) and held root on internal servers. Recovered scripts sprayed passwords over SSH against more than 55 internal machines, planted web shells, added SSH keys, searched for stored credentials, and targeted RADIUS subscriber credential databases, though exfiltration was not confirmed. The toolkit included a full exploit for FortiGate SSL-VPN flaw CVE-2024-21762 against mail.3bb.co[.]th, but the initial access vector is unestablished, and a cleanup script erased logs while preserving the backdoor.

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.

ConnectWise Patches ScreenConnect Vulnerability Exploited in Worm-Like Attacks

ConnectWise patched critical ScreenConnect flaw CVE-2026-84869 (CVSS 9.9) exploited since August 20 in worm-like attacks; CISA added it to KEV.

ConnectWise released urgent patches for CVE-2026-84869 (CVSS 9.9), a missing authorization and improper privilege management flaw in ScreenConnect allowing file transfer and execution through active remote sessions without host confirmation. Huntress reported in-the-wild exploitation since August 20, with attackers using rogue ScreenConnect clients to push four VBScript files for persistence and worm-like propagation to other ScreenConnect clients. The flaw is fixed in ScreenConnect 26.6.5, with disabling the TransferFiles permission as a temporary mitigation. CISA added the CVE to its KEV catalog, requiring federal agencies to patch within three days under BOD 26-04.
