IT & OT — stories from SecurityWeek, BleepingComputer, The Hacker News, Industrial Cyber + advisory watch: CISA, BSI, Ofgem
The week of appliance zero-days rolls on, and today it’s squarely in security appliances. Palo Alto Networks confirmed limited in-the-wild exploitation of CVE-2026-0322, an authentication-required root RCE in the PAN-OS management interface, and CISA has already added it to the KEV catalog with a federal mitigation deadline of October 17. Ivanti’s Connect Secure saga from yesterday escalated into a formal CISA warning, meaning federal agencies must now patch CVE-2026-104935 too. Cisco patched yet another actively exploited zero-day in Secure Email Gateway — the second this quarter — reachable by a plain email attachment. Ledger’s hardware-wallet implant story grew into a genuine supply-chain crisis: confirmed tampered devices traced to reseller CryptoBilis, sales halted across Southeast Asia and Hong Kong, and competitors Trezor slashing their reseller networks. In enforcement news, the FBI’s “Lonestar Roundup” raid dismantled North Korean laptop farms in Texas, seizing 187 machines used by DPRK operatives posing as remote US IT workers. BSI has no new critical advisories overnight beyond routine updates; Ofgem remains quiet.
Palo Alto Networks confirmed limited exploitation of a high-severity (CVSS 8.6) flaw in the PAN-OS management interface, letting authenticated attackers with network access to the management plane execute code as root. It affects PA-Series and VM-Series firewalls plus Panorama and M-Series appliances; Cloud NGFW and Prisma Access are not affected. Exploitation requires valid credentials and management-interface access — which is why the primary mitigation is restricting the management interface to trusted internal IPs. Fixes are out for PAN-OS 10.2, 11.1, 11.2, 12.1 and 12.2, with a 11.2.16 fix due October 15. Threat Prevention signatures offer only limited protection. Palo Alto shared three attacker IPs: 66.42.72[.]14, 208.83.239[.]114, 149.248.47[.]234. CISA added it to KEV; federal agencies must mitigate by October 17.
Takeaway: Verify your firewalls’ management interfaces are not internet-reachable, patch to the fixed builds this week, rotate management credentials, and check logs for those three IOCs.

Yesterday’s Ivanti story (UTA0576 chaining three zero-days to root on fully patched appliances) now has a CISA alert urging admins to patch immediately. Reminder of where we stand: CVE-2026-104935 (auth bypass + RCE) is fixed in ICS 22.8R2.5, 25.1.1.2, 25.1.3.0 and 25.1.3.1; the privilege-escalation flaw in the chain is still unpatched. The attacker re-exploited the device per command and tampered with logs, defeating the Integrity Checker Tool. Log review should reach back to October 1 at minimum.
Takeaway: This remains the week’s top priority action — patch, hunt, rotate credentials, and don’t rely solely on the integrity tool.

Cisco fixed CVE-2026-76519, a path-traversal flaw in SEG’s Advanced Malware Protection (File Reputation / Content Scanner Tools < 25.3.0.5525) that lets unauthenticated attackers achieve root command execution by sending a crafted email attachment. Cisco PSIRT confirmed active exploitation in October. Indicators of compromise are published, cloud instances are already mitigated, and Cisco advises checking firewall/network logs for suspicious transfers since attackers may erase evidence. Roughly 300 SEG instances are internet-exposed (Shadowserver). Note: this is Cisco SEG, not your IOS switches — but it’s the third SEG zero-day in recent memory (CVE-2024-20401, CVE-2025-20393, CVE-2026-76461).
Takeaway: If any Cisco SEG/SEWM appliances exist in your estate (including partner-managed mail security), check the Content Scanner Tools version and apply the fix today.

The Ledger story matured from isolated reports into a confirmed supply-chain attack: Ledger’s Donjon lab confirmed a hardware implant — a separate microcontroller that detects and decodes the 24-word recovery seed phrase and exfiltrates it over LTE via a provisioned eSIM — leaving the Secure Element and OS untouched and defeating integrity self-checks. Confirmed losses trace to reseller CryptoBilis (Southeast Asia), with reports also from a Singapore airport tech retailer and MediaMarkt in Europe (pulled from shelves; distributor Aqipa GmbH). Ledger ordered a sales halt across Indonesia, Singapore, Thailand, the Philippines, Vietnam, Malaysia and Hong Kong. Trezor is preemptively terminating most reseller partnerships by January 1, 2027, citing supply-chain hardening.
Takeaway: The lesson generalizes: integrity checks embedded in software can’t catch physical-layer implants. Relevant to any hardware procured through third-party channels — including OT devices.

The DoJ disrupted the Famous Chollima (WageMole) DPRK IT-worker scheme: two US nationals arrested, 14 charged, ~187 laptops and KVM devices seized across 40 searched residences. The farms hosted employer-issued laptops that North Korean operatives — using stolen or fabricated identities — accessed remotely to appear US-based, sometimes redirecting shipments by faking theft reports or abusing IT staffing roles. An Ohio indictment describes a 2019–2025 scheme affecting 70 US companies and generating ~$3M for the regime. CrowdStrike warns identification pressure is pushing operatives toward device-identifier spoofing and reuse across victim orgs.
Takeaway: HR/onboarding controls matter: identity verification for remote hires, asset-return processes, and monitoring for anomalous KVM/network patterns are cheap defenses against this scheme.
