Week in review: Refrigeration cyberattacks hit European retailers again, Patch Tuesday forecast

Here’s an overview of some of last week’s most interesting news, articles, interviews and videos:

Week in review

The first ten lines of a command policy for AI coding agents
In this Help Net Security interview, Vinay Thakker, CTO of KloudStax, explains how to set identity, credentials, and network limits for AI agents. He argues that agents should run under their own identity, with the person’s identity attached when acting on someone’s behalf.

Google disrupts XCPE botnet, bans the company behind it
Google shut down the servers behind XCPE, a backdoor hidden in the firmware of Android TV set-top boxes. Google’s Threat Intelligence Group attributes the operation with high confidence to Videostrong Technology, the company that manufactured many of those boxes. More than 1.3 million devices were enrolled.

Fireperf: Open-source network testing tool for firewalls and routers
The IPFire project has released fireperf, an open-source measurement tool that opens connections at a fixed rate and reports what the device in the middle did with each one. It is free software aimed at administrators, developers and testers who evaluate firewalls, routers and other systems that keep a state for every connection.

AI coding agents are installing MCP servers that will never be patched
When a developer tells an AI coding agent to “set up a GitHub MCP,” the agent has to pick a package. New research from Glow Labs documents sessions where it picked one out of an archived repository that will never be patched again.

What human hackers still do better than AI, according to HackerOne’s CEO
AI can find vulnerabilities in minutes, but people still hold the edge in judging what a flaw means for a business. In this Help Net Security interview, Kara Sprague, CEO of HackerOne, talks about business logic bugs, what AI does to the crowd model, and why routine medium-severity findings may pay less.

What AI-generated malware looks like under the microscope
In this Help Net Security interview, Lindsay Kaye, VP of Threat Intelligence at HUMAN Security, talks about what AI-generated malware looks like on the bench. She points to tidy comments, uniform logging messages, and emojis as signs a script came from a model, and notes that decompiled code strips much of that away.

AI agent detection signals that still work when agents look human
Bots follow a script. AI agents work toward a goal and choose their own steps, which makes them harder to catch. In this Help Net Security interview, Zohaib Ahmed, CEO of Resemble AI explains how agents arrive as declared, undeclared or disguised traffic, and why binary bot detection misses the last two groups.

A banking malware sample led researchers to an Android bug that can loop-crash phones
Bitdefender Labs researchers built an Android app that contains no executable code and requests no permissions, and installing it leaves a Pixel 10 in a crash loop that can take a factory reset to clear. The flaw, which Bitdefender calls GhostMap, comes from how Android reads the ZIP structure inside an APK.

Security certification is a snapshot, and buyers read too much into it
In this Help Net Security video, Mariia Bakhtina, a research specialist at Masaryk University, explains what a Common Criteria or FIPS-140 certificate does and does not promise. In her team’s analysis, about 6 in 10 vulnerabilities matched to certified products, smartcards aside, were disclosed after the certification date.

Chainalysis breached using “offensive agentic techniques”
Blockchain analytics firm Chainalysis has suffered a cybersecurity incident that led to a data breach. According to the company’s Friday announcement, the incident is unrelated to the recent Binance hack.

Second wave of refrigeration cyberattacks hits European supermarkets
Three weeks after the attack that turned refrigeration units in French supermarkets into ovens overnight, similar cyberattacks have hit shops in other European countries and again caused refrigerated food to be spoiled.

CISA added two new Ivanti Connect Secure vulnerabilities (CVE-2026-111357, CVE-2026-118527) to its Known Exploited Vulnerabilities catalog on Friday, after Ivanti updated an earlier security advisory with details about the flaws.

AI agents scale and speed up Chinese-linked attacks
A China-nexus espionage group used AI agents to attack more than 200 organizations in 11 days, CrowdStrike said last week. On Monday, Kaspersky published details of a separate campaign against educational institutions in Africa and Latin America, mounted by Chinese-speaking operators.

Poisoned cPGuard update hits thousands of web hosting servers
An attacker has compromised the update infrastructure of cPGuard, a security suite for Linux web hosting servers, and pushed out a malicious update to nearly 3,000 customer servers. OPSShield, the company behind the security suite, also confirmed that the attacker made off with customer contact information and hashed passwords from the firm’s billing and licensing server.

Cyberattack hits French blood banks
Three blood banks have detected and reversed a potentially destructive temperature spike in their cold rooms, following a cyberattack that targeted a refrigeration equipment provider of the French Blood Establishment (EFS), the only civilian blood collection and transfusion organization in France.

Patched Zyxel GS1900 switches remained open to in-the-wild exploit (CVE-2026-107441)
Zyxel GS1900 series network switches that received a fix for a flaw that was later reported to have been exploited in the wild are still open to an exploit attackers used, Binarly found. That’s because the patch fixed a different bug (CVE-2026-7273) from the one (CVE-2026-107441) the exploit actually relies on.

Secure your containers without breaking what works
Container security has a familiar problem. Teams identify vulnerabilities, but turning those findings into lower risk is much harder. A standard container image may include operating-system packages, development tools, debugging utilities and libraries that an application never uses. Each unnecessary component can expand the attack surface and add vulnerabilities to investigate, patch or explain during an audit.

Live Q&A: CISSP exam prep with ISC2 experts
ISC2 hosted a live Q&A about the CISSP exam on November 6, 2026, at 7:00 p.m. CET. Experts answered questions, explained certification requirements, reviewed the exam domains, and shared self-study resources and training options.

Ghostunnel: Open-source TLS proxy with mutual authentication
Ghostunnel is an open-source proxy that handles TLS for programs that cannot handle it themselves. It works in two directions. In server mode it sits in front of a backend, accepts TLS connections, checks the client’s certificate, then passes traffic to the service behind it over TCP or a UNIX socket. In client mode it does the reverse, listening for plain local connections, wrapping them in TLS and presenting a client certificate to the remote service.

Open-source file sync tool rsync 3.5.2 fixes a CPU exhaustion flaw
The rsync project released version 3.5.2, and it closes a flaw that let a connecting client tie up a server’s CPU with checksum math that leads nowhere. The new version also lets you push a transfer to the back of the queue for CPU and disk, so a big sync stops elbowing everything else on the machine.
