PHP2Shell update: suspected North Korean hackers line up targets as shutdowns hit Japan's emergency alerts and Bangladesh's banks

Security firm CYFIRMA says a suspected North Korea-linked group is slowly and quietly probing 216 unpatched or partly protected PHP servers belonging to governments, banks, airports and online payment platforms in more than a dozen countries, using the PHP2Shell flaws (CVE-2026-109618 and CVE-2026-109619). Separately, Palo Alto Networks' Unit 42 has withdrawn its claim that an attack on a European government agency used PHP2Shell, saying it cannot confirm how the attackers got in. The precautionary shutdowns are still causing disruption: more than 500 service suspensions have been counted in Japan, where SoftBank paused emergency alert emails and NTT Docomo paused some disaster-information messages, while Bangladesh Bank and several other Bangladeshi banks and government sites took their websites offline. There are still no confirmed successful PHP2Shell break-ins.

Why it matters: Quiet, targeted scanning by a state-linked group is more worrying than the noisy mass scanning seen so far, and the main targets are exactly the kinds of organisations that hold money and personal data. Website owners should update PHP to 8.5.12, 8.4.27, 8.3.36 or 8.2.35 and check logs for suspicious activity. If you're in Japan and rely on carrier alert emails, use another official alert app until your provider confirms the service is back.

Holiday-rental software firm SECRA says hackers stole guest data, possibly including key-safe codes

SECRA Bookings, a German company owned by holiday-rental group HomeToGo that makes booking and channel-management software for holiday homes, says it discovered on 23 October that attackers had broken into its systems and exported data. It says it must assume the stolen data includes guests' names, contact details, addresses, dates of birth and nationality, and in some cases bank details (IBAN/BIC), ID document numbers and access codes for key safes. HomeToGo told investors the incident appears limited to SECRA, and data protection authorities have been notified.

Why it matters: Criminals could use real booking details, such as your name, arrival date and the property you booked, to send very convincing fake messages asking for payment. Only pay and talk to hosts through the official booking platform, confirm key-safe codes with the property before you travel, and watch your bank account for unexpected direct debits. Hosts should reset door PINs and key-safe codes and change all SECRA passwords and integration keys.

Seoul police bust ring accused of using AI to steal 8.2 million personal records

Police in Seoul say seven suspects stole 8.2 million pieces of personal data and other internal records from more than 90 organisations, including hospitals, private academies and businesses, between September last year and recently. The group is suspected of using AI tools to hack 60 of the targets and of trying to extort some of them, demanding a combined 360 million won (about US$272,000) from 38 victims. The alleged ringleader, who police say learned hacking while doing mock attacks at a security company, has been referred to prosecutors.

Why it matters: It's a real-world example of criminals using AI to scale up break-ins against organisations that hold sensitive data, such as hospitals. If you get an unexpected message claiming to come from a clinic or company you use, especially one asking for money or personal details, check it through the organisation's official contact details.

A booby-trapped file in a Downloads folder tried to trick an AI coding agent into installing malware

Security firm Forever Security found a malicious AGENTS.md file, a plain-text instructions file that AI coding agents read automatically, in a customer's Downloads folder, which the customer was also using as the agent's working folder. The file was disguised as engineering notes and told the agent to install a known-malicious npm package called function-color; the attempt was stopped before any code ran. The researchers showed that a web page can silently save such a file into Downloads in some browsers, and reproduced the trick against OpenAI Codex, with a related technique against Claude Code that leaked its login token.

Why it matters: AI agents follow instructions in the folders they're started in, so untrusted files can effectively give them orders. Never run a coding agent from your Downloads or home folder; start it in the specific project folder, check any unfamiliar AGENTS.md or CLAUDE.md files, and keep approval prompts and sandboxing switched on.

Unpatched Tailscale SSH flaws could let one hacked device gain root on other servers, researcher says

Unpatched Tailscale SSH flaws could let one hacked device gain root on other servers, researcher says

A report called Tailworm, published by a researcher at Cyberdione Labs, describes 11 findings in the Tailscale private-networking software and its self-hosted alternative headscale. The most serious is that, in lab tests, an attacker who already controls one device on a Tailscale network could abuse Tailscale SSH port forwarding to get full administrator (root) access on other servers that device is allowed to reach. There is no patch, CVE or security bulletin yet; Tailscale says it is working on fixes but is not telling everyone to switch off Tailscale SSH, and the findings have not been independently reproduced.

Why it matters: A flaw that turns one compromised laptop into access to many servers is serious. Until a fix arrives, admins should turn off SSH port forwarding where possible, write access rules as narrow one-device-to-one-server pairs, enable Tailnet Lock and key expiry, and remove app-connector permissions that aren't needed.

Hackers copy personal data of Portugal's firefighters, including ID numbers and blood groups

Portugal's civil protection authority, ANEPC, has told regional commands that the national firefighter register (RNBP) was hit by a cyberattack and that a copy of the personal data was made. The data includes full names, citizen card, tax, social security, health service and driving licence numbers, dates of birth, contact details, addresses, photos and blood groups, but no bank details. The application has been suspended, and the head of the Portuguese Firefighters' League says the register holds about 60,000 records.

Why it matters: A single record holding this many official ID numbers is valuable for identity fraud. ANEPC warns that firefighters may be targeted by phishing emails, scam texts, phone calls and malicious QR codes, and should be extra careful with any unexpected request to open a link or website.

Japanese email marketing service Blastmail confirms mailing lists leaked for 344 customers, with no restart date

Rakus Light Cloud, a subsidiary of Japan's Rakus, says attackers broke into two of its API servers, ran commands and reached the databases behind its Blastmail email distribution service. Mailing lists and other delivery data have now been confirmed leaked for 344 customer contracts, including 56 newly identified ones, and details of every contract holder, such as company names, contact names, phone numbers, email addresses and payment histories, were taken from a sales system. The company says it doesn't hold card numbers; Blastmail has been suspended since 21 October and there is no date for it to return.

Why it matters: When an email marketing provider is breached, the leaked mailing lists belong to many separate businesses, so people who never dealt with the provider directly can still be affected. Expect more convincing spam and phishing that appears to come from companies you subscribe to, and be wary of links in unexpected newsletters.

From today, curl handles low and medium-severity security bugs in public to cope with an AI-fuelled flood of reports

The curl project, which makes a widely used open-source data-transfer tool, now asks researchers to report low and medium-severity vulnerabilities as public GitHub issues; only high and critical ones stay private on HackerOne. Lead maintainer Daniel Stenberg says the change is entirely triggered by an 'avalanche' of reports, many generated with AI, and that over 90% of submissions in recent years were quickly judged less than high severity. He admits that handling minor flaws in the open gives attackers a slightly longer window, but says the team must act to survive.

Why it matters: It shows the strain AI-generated bug reports are putting on the volunteer projects that much of the internet relies on. For most people the advice doesn't change: keep your software and devices updated, because fixes for curl reach you through your operating system and apps.
