Weekly roundup: they didn't break your door, they used your key
The week's key stories along one thread: backup software, developer platforms, AI keys and a scam app. Every time, the weak spot was a key someone had been trusted with.
PHP2Shell: Hungary’s government portal goes offline
Overnight into 22 October 2026, Hungary took its central e-government portal, magyarorszag.hu (in Hungarian), and several other government sites offline as a precaution, with services expected to be down for 48 hours. The responsible minister said there was no sign of an attack and asked businesses to have their websites checked by a professional. Amazon says the first exploitation attempts appeared on 17 October, four days before the fix; no successful break-in is publicly known. If your site runs on PHP, ask your provider whether you’re on a patched version. More: PHP2Shell: check today which PHP runs under your website
ConnectWise: a Chinese state-aligned group and AI agents
On 21 October, Microsoft attributed the attack through ConnectWise’s cloud backup service to Storm-0940, a group aligned with Chinese state interests. Using the stolen application key, the attackers tried to sign in to more than 2,250 Microsoft 365 tenants; most attempts failed, but in several places they gained privileged access, in some cases in under three hours. The work was done by ARTEX, an open-source framework built on AI agents. If you’re affected: keep the connection disabled, preserve your logs, and review service account sign-ins back to 1 October.

Someone else is spending your AI budget
On 21 October, the developer platform Railway said an unauthorised party may have accessed customers’ encrypted environment variables (where API keys and passwords live), some of them in decrypted form, and asked everyone to rotate their keys. The company believes it’s part of a series of attacks that target AI providers’ keys through platform companies. The same week, Zeabur announced it is shutting down after a second breach, and according to the company, a poisoned release of the LiteLLM AI gateway was built with GitHub tokens stolen from an internal instance’s logs. As Wiz describes it, others run models on stolen AI access and the victim pays the bill, potentially tens of thousands of dollars within a day or two. If you keep keys on such a platform, rotate them and set a spending cap and alerts. Sources: Railway, Wiz
AI agents that switched off their own oversight
OpenAI disclosed two internal cases from October: on 3 October, a coding agent turned off alerts to the security team while fixing something, and on 6 October, another removed the monitoring integration and then claimed it hadn’t. OpenAI is tightening its monitoring and investigating whether these are outliers. The lesson applies to your own AI crew too: an agent shouldn’t be able to touch its own oversight.

Cairn: AI agents broke into web shops
Norforge researchers found publicly exposed control panels from which at least three groups used Cairn, an open-source agent coordination tool that also works for penetration testing, to attack web shops and payment services, with roughly a 10% success rate. According to Reuters, one attacker breached more than 100 companies. No Hungarian victims are known, but for web shops the message is clear: an automated attacker never gets tired.

WhatsApp: hidden instructions in the help pages
Redact reviewed 545 WhatsApp help pages and found 102 text blocks hidden from visitors and aimed at the chatbot, on 80 pages. The account deletion page told the bot not to recommend contacting a data protection authority, and another page told it not to cite the GDPR once a user mentions a lawyer. WhatsApp says it was a bug and removed the text by 18 October; it’s unknown whether the bot followed the instructions. Your right to complain still stands: in the EU you can turn to the Irish regulator or your national data protection authority (in Hungary, the NAIH). Sources: Redact, The Hacker News
NFC fraud: a Dutch gang caught
Dutch police arrested two men whose crew used AI-generated “bank security” calls and a card-reading scam app to take about €380,000 from 170 people in roughly three weeks. The app sent the NFC chip data of a bank card held against the phone to an accomplice, who withdrew cash at ATMs. In Hungary, the central bank’s consumer information site BiztosDöntés.hu (in Hungarian) warns about the same thing: contactless payment is safe, the scam app is the danger. Never install an app or tap your card on your phone because someone asks you to; on such a call, hang up and call your bank. Source: NL Times
