Keys to the Kingdom: Erlang/OTP SSH Vulnerability Analysis and Exploits Observed in the Wild
Attackers actively exploit CVE-2025-32433, a CVSS 10.0 unauthenticated RCE in Erlang/OTP SSH, heavily targeting OT and critical infrastructure networks.
CVE-2025-32433 enables unauthenticated RCE in Erlang/OTP's SSH daemon via SSH connection protocol messages (codes >= 80) processed before authentication, affecting versions before OTP-27.3.3, OTP-26.2.5.11 and OTP-25.3.2.20. Unit 42 recorded a spike in exploitation between May 1-9, 2025, with 70% of detections on firewalls protecting OT networks, disproportionately affecting healthcare, agriculture, media and high technology. Observed payloads bind TCP-connected shells or launch Bash reverse shells to hosts like 146.103.40.203:6667, with randomized DNS lookups under dns.outbound.watchtowr.com indicating OAST-driven blind RCE validation.

Hackers Actively Exploiting FortiGate Firewalls to Deploy Custom Node.js Malware
Attackers actively exploit CVE-2025-25249 in FortiGate firewalls to deploy PivotC2, a Node.js RAT that decrypts VPN and admin credentials.
SOCRadar assesses with high confidence that threat actors are actively exploiting CVE-2025-25249, a CVSS 9.8 heap buffer overflow in the cw_acd daemon (CAPWAP, UDP 5246) affecting FortiOS 6.4-7.6.3 and FortiSwitchManager 7.0.x/7.2.x. Attackers deploy fortirun.bin and PivotC2, a Node.js post-exploitation framework that harvests configurations and decrypts SSL-VPN, wireless, and admin credentials using AES-256-CBC and AES-128-GCM. Over 30,000 FortiGate IPs were scanned and 178 devices compromised, including two confirmed full intrusions of US organizations with Exchange mailbox exfiltration to Wasabi storage. STRU attributes the campaign to a Russian-speaking, financially motivated cybercrime operator.

macOS Screen Sharing Flaw Exploited to Deploy Monero Miners
Dutch NCSC confirms active exploitation of critical macOS Screen Sharing flaw CVE-2026-65400, granting root access and installing Monero miners.
CVE-2026-65400 (CVSS 9.8) is an authentication state-management flaw in macOS's built-in Screen Sharing that lets network attackers authenticate without valid credentials. The Dutch NCSC confirmed active exploitation against systems with port 5900 exposed to the internet; in every documented case attackers obtained root access and installed a Monero cryptocurrency miner. Apple patched the bug in macOS Tahoe 26.6.1, Sequoia 15.7.9, and Sonoma 14.8.9, crediting Alfredo Pesoli of Bynario. A related researcher scan found roughly 40,000 exposed Screen Sharing hosts, and security firm Calif built working exploits for related flaws in about four hours using an AI coding agent.

StyleSmuggler: The Magento Zero-Day Behind New Store Attacks
Sansec reports actively exploited Magento/Adobe Commerce zero-day StyleSmuggler enabling unauthenticated RCE and Rust backdoor installation on fully patched stores since September 4.
Sansec discovered StyleSmuggler, an unpatched zero-day in Magento Open Source and Adobe Commerce, affecting all current versions including 2.4.7, 2.4.8 and 2.4.9, with attacks observed since September 4. The two-stage attack poisons Magento's template system via the styles property and executes the injected PHP during 'Payment Transaction Failed Reminder' email rendering, working even when email delivery fails and when sessions are moved to Redis. Successful compromise installs a lightweight Rust backdoor disguised as fc-cache or chronyd that beacons every 60 seconds with 48-byte UDP packets to NTP port 123 at ntp.timesync.to. A second attacker deployed a PHP web shell in product-image cache directories, hidden behind 404 responses unless a correct X-Cache-Token header is present.

2026-002: Multiple Vulnerabilities in Cisco Products
Cisco fixed SD-WAN Controller auth bypass CVE-2026-20127 (CVSS 10) exploited in the wild since 2023, plus several critical and high flaws in SD-WAN Manager.
On 25 February 2026 Cisco released advisories for multiple flaws in Catalyst SD-WAN Controller and SD-WAN Manager, potentially granting administrative access to attackers. CVE-2026-20127 (CVSS 10.0) is an authentication bypass in the Controller's peering authentication mechanism, exploited in the wild since 2023, allowing unauthenticated admin access via NETCONF, rogue device injection, and persistent access. SD-WAN Manager flaws include CVE-2026-20129 (9.8, unauthenticated API auth bypass to netadmin), CVE-2026-20126 (7.8, local privesc to root), CVE-2026-20133 (7.5, info disclosure), CVE-2026-20122 (7.1, arbitrary file overwrite), and CVE-2026-20128 (5.5, DCA info disclosure). CERT-EU recommends patching, capturing forensic evidence, IOC hunting, and restricting management-plane internet exposure.

StyleSmuggler: Magento and Adobe Commerce 0-day RCE (CVE-2026-75650) under active attack
Sansec details actively exploited StyleSmuggler 0-day (CVE-2026-75650, CVSS 10.0) unauthenticated RCE in Magento and Adobe Commerce, patched by Adobe hotfix APSB26-146.
Sansec is investigating StyleSmuggler, an actively exploited unauthenticated remote code execution chain in Magento Open Source and Adobe Commerce, now tracked as CVE-2026-75650 with CVSS 10.0. Adobe released hotfix VULN-39341 via APSB26-146 (priority 1) on September 7 for versions 2.4.4 through 2.4.9, but stores were being exploited for roughly three days before the fix existed. The implant is a Rust backdoor that disguises itself as kworker, fc-cache, or chronyd processes and exfiltrates host data in MessagePack records sent as fake NTP replies over UDP port 123. Adobe advises rotating the encryption key and every credential it protected, and Sansec stresses patching does not clean already-compromised stores.

NSA, CISA, FBI, DOE, and EPA Warn of Active AI
Five US agencies warn of active AI-assisted attacks on internet-exposed Siemens S7 PLCs across critical infrastructure, using disguised snap7 scripts for pre-positioning reconnaissance.
NSA, CISA, FBI, DOE, and EPA issued joint advisory CISA AA26-231A warning of an active hacking campaign against Siemens S7-series PLCs, from S7-200 through S7-1500 F-series, across US critical infrastructure. Threat actors use internet scanning services such as Censys and ZoomEye to locate exposed controllers, then perform read operations over S7comm on TCP port 102 using the legitimate snap7.dll and python-snap7 libraries, disguising AI-generated exploitation scripts as monitoring tools. The agencies assess the activity as pre-positioning ahead of possible process disruption, equipment damage, or safety incidents in Energy, Water, Critical Manufacturing, Chemical, Food and Agriculture, and Commercial Facilities sectors.
