IT Security News Roundup: 2026-10-27 Afternoon

IT Security News: Afternoon roundup, 2026-10-27

Summary

The most pressing thread was active exploitation of critical PHP flaws, now confirmed by CISA and researchers, alongside emergency fixes from Microsoft, Apple and Tailscale. Healthcare stayed in focus, with the University of New Mexico recovering from a cyberattack while a new US pilot offers rural hospitals free security help. Law enforcement had a busy stretch against ransomware and fraud crews, and several stories showed attackers exploiting trust, whether in AI coding agents, third-party suppliers or abandoned software. For defenders, the common lesson is to patch quickly, know your assets and treat supply chains and AI tooling as part of the attack surface.

1. The University of New Mexico canceled classes for a second day after a cyberattack on its Health Sciences Center. Hospitals are accepting patients again after ambulance diversion, but recovery will proceed in phases.
2. Police arrested nearly 50 suspects in an international operation against a drug trafficking network with Western Balkan members. The network is linked to killings, kidnappings and grenade attacks across Europe.
3. Guardicore Labs describes an opportunistic ransomware campaign against MySQL servers. Attackers use double extortion and publish stolen data to pressure victims, so exposed databases remain a prime target.
4. EPICS Base 7.0.10 and earlier has critical flaws (CVSS 9.8) that could enable denial of service, memory corruption, information disclosure or code execution. The EPICS Community recommends updating to 7.0.11.
5. CISA and security researchers confirmed successful exploitation of the PHP flaws, after earlier warnings were slow to materialize. This puts the security community under greater scrutiny and raises the urgency to patch.
6. Mitsubishi Electric warns that its GENESIS64 and ICONICS product family is affected by a libwebp code-execution flaw and by authentication bypass and privilege issues. Some products are listed as affected in all versions.
7. Microsoft released emergency .NET updates fixing a Brotli memory flaw and a Linux privilege escalation. It also corrected two October security patches that were incomplete.
8. Law enforcement seized KillSec's leak site on 30 September, securing at least 110 terabytes of stolen data. A teenager is suspected of leading the ransomware group.
9. Malwarebytes lists five election-related scams that ask people to register, donate, take surveys or buy merchandise. The advice is to verify messages before clicking or paying.
10. Researchers found an OpenAI API compaction flaw that exposed hidden AI reasoning traces. OpenAI fixed it and paid a $6,000 bug bounty.
11. Dutch police arrested two men suspected of stealing over €380,000 from 170 victims using NFC relay attacks. The scheme combined AI-generated robocalls, fake bank staff and malicious apps, and servers were seized.
12. A deception-technology write-up shows attackers brute-forcing RDP credentials and being diverted into honeypots. The attackers dropped a previously undetected malware the researchers named Trojan.sysscan.
13. Attackers have infected 953 online stores with a scanner-evading JavaScript loader since July 2025. The long-running campaign shows how e-commerce sites can stay compromised unnoticed.
14. Researcher Ovi analyzed uCreator, a commercial Android spyware kit that steals Telegram 2FA passwords and clones WeChat accounts. It overlaps technically with the Baohuo backdoor, and an exposed GitLab server revealed a rentable control platform.
15. Guardicore describes the Nansh0u campaign, with attacks seen in its sensor network originating from South African IP addresses hosted by VolumeDrive. The text points to an expanding attacker toolset.
16. Forever Security found that a disguised AGENTS.md file in a Downloads folder can push AI coding agents to install malware. OpenAI's Codex followed the instructions in over 90 percent of test runs, and Claude Code was tested with a crafted CLAUDE.md.
17. A Red Hat survey of 1,400 CIOs examines how EMEA enterprises are handling software supply chain security as autonomous AI agents and AI-enabled workflows move into production.
18. The DataBreaches.Net author reports that a backup failure caused the loss of media files and documents attached to posts. They were also offline for days due to hospitalization and are now catching up.
19. A UK inspectorate found that hackers breached third-party IT suppliers holding police data several times this decade. The finding highlights supplier risk for sensitive public-sector data.
20. Apple's iOS 27.2 fixes 163 security vulnerabilities, including WebKit and privacy flaws. IT teams should review and roll out updates across managed devices.
21. The US national cyber director launched a six-month pilot in South Carolina connecting rural hospitals with industry for free cybersecurity services. It follows a similar initiative in the water sector.
22. Vulnerability management fails when asset data is unreliable. Without a current picture of systems, owners and business importance, scanners miss systems and findings have no one responsible for fixing them.
23. An abandoned Popcorn Time fork left millions of computers exposed through an insecure updater. Researchers disabled it, and users are urged to remove the software.
24. ISC2 launched the Cyber-AI Workforce Coalition, a vendor-neutral group to map future AI security careers, according to CEO Scott Beale. It addresses the skills gap as AI reshapes security work.
25. Tailscale is preparing patches for the "Tailworm" flaws in Tailscale SSH after details were published over the weekend, before any fixes were available. The disclosure was uncoordinated, leaving users exposed in the interim.
