An unknown threat actor has infected 953 online stores, most of them running Magento, as part of a long-running campaign active since July 2025. According to Dutch e-commerce security company Sansec, the activity is designed to add a small piece of code to the store's pages that, when visited by unsuspecting users, serves malicious JavaScript loader code through Magento CMS blocks. "When you visit, that code makes your browser ask the group's server what to do next," Sansec said . "The server first checks whether you are a real shopper or a security scanner, so scanners get nothing." No less than five distinct domains have been observed over time in connection with the campaign - manulfie[.]click, first seen in July 2025 neswnsssn[.]click, first seen in December 2025 lanhd6549tdhse[.]top, first seen in March 2026 additionalver[.]com, first seen in June 2026 deepveindrilling[.]com, first seen in October 2026 Sansec said it found deep...

Cybersecurity researchers are calling attention to what they say is a "recurring social engineering pattern" across hundreds of cases in which threat actors use Microsoft Teams' external chat creation feature to conduct impersonation scams or to deliver malware. "A consistent pattern of attacker behavior has emerged across these incidents: the use of the same throwaway tenants, the same 'IT Support (Internal)' display names, the same remote-access tools, and increasingly, the same payload domains," Arctic Wolf Labs said in a report shared with The Hacker News. The attacks consistently employ IT-themed display names or friendly-sounding first names to subvert external-user warnings in Teams. These messages originate from Teams identities established through newly created or acquired Microsoft 365 tenants. Nearly 30–40% of the cases investigated by the cybersecurity company involve the use of *.onmicrosoft[.]com , a permanent fallback domain auto...

This2Shell, That2Shell, Everything2Shell. That's pretty much how the last week went. Critical bugs that let attackers run code remotely are showing up everywhere. Hackers are scanning for targets, some flaws are already being used in attacks, and security teams have more urgent patches than they can keep up with. And that's not even the full story. A leaked key led to a software supply-chain attack. AI agents are being tricked into following harmful instructions. Old bugs are still being used to break into systems, and some attacks are so simple it's hard to believe they still work. Some websites even went offline to avoid taking chances. It's been a rough week for anyone trying to keep systems safe. Here's what happened. ⚡ Threat of the Week PHP2Shell Flaws Puts Organizations on Alert — The PHP Foundation released patches for two critical vulnerabilities in PHP, CVE-2026-109618 and CVE-2026-109619, that could lead to unauthenticated remote code execution...

A rentable Android spyware kit called uCreator takes over Telegram and WeChat accounts by hiding its code inside working copies of the two apps, researcher Ovi found . It only reaches people who install one of these tampered copies, spread outside the official app stores, or who run WeChat inside the kit makers' own container app. The kit's Telegram part matches Baohuo , a backdoor that Doctor Web reported in October 2025 . Doctor Web found Baohuo in tampered copies of Telegram X, an Android app from Telegram. At the time, the company estimated that more than 58,000 devices were infected. The Hacker News compared the two reports. Doctor Web's technical description of Baohuo lists the same code namespace, com.ucreator.tgjar , the same command-and-control (C2) server, and matching command names as Ovi's analysis. Ovi's analysis, published October 21, 2026, does not mention Doctor Web's findings, and Doctor Web did not name the kit. It is not clear whether...

A malicious instruction file sitting in a developer's Downloads folder tried to make their AI coding agent install a known-malicious npm package, security firm Forever Security said in a report published last week. The company caught the attempt on a real customer's machine and stopped the agent before any code ran. It could not determine how the file got into the folder. The file was  AGENTS.md, a plain-text instructions file that a coding agent, such as OpenAI's Codex, reads when it starts in a folder and follows as directions. It was dressed up as ordinary engineering notes. One section told the agent to add a server to its own configuration and install a package called function-color from npm. That package is part of a malware campaign that other researchers have  documented separately : function-color pulls in a downloader called function-flag, which fetches and runs a Windows payload. Researchers at CloudSEK and Checkmarx, who ...
