Attackers Use Microsoft Teams IT Support Scams to Deploy Malware and Ransomware

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...

⚡ Weekly Recap: This2Shell, That2Shell, Everything's an RCE? Rogue AI, Supply Chain Chaos and More

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...

Two Critical Wasmtime Flaws Could Let Malicious WebAssembly Modules Escape Sandboxes

Two critical flaws in  Wasmtime , a WebAssembly runtime that can be built into other software, could allow a malicious WebAssembly module to escape the sandbox intended to contain it, the project's maintainers say. An attacker would first need a vulnerable Wasmtime build to compile a module they control, and one of the flaws affects only ARM64 systems. Fixed versions were released on October 19 and 20, and the maintainers have not reported any attacks. Wasmtime runs WebAssembly code outside web browsers. Both bugs are in Cranelift, the compiler it uses by default to turn WebAssembly into machine code. Wasmtime's maintainers at the Bytecode Alliance rated each flaw 9.9 out of 10 on the CVSS scale in advisories published on October 19. CVE-2026-115889  affects Wasmtime across all processor architectures. CVE-2026-115893  affects only ARM64, also called aarch64. The sandbox is meant to keep a module inside set limits. A module can only use its own memory and...

Between alerts: What Attackers Do in the Spaces Ordinary Detection Misses

Every SOC struggles with a pile of alerts. Very few of those alerts explain how an attack started or how it progressed. Network data, like that from a network detection and response (NDR) platform, connects individual alerts into one timeline, and it feeds the defensive systems that can tie all events together into one coordinated view. SOC teams often first see the shape of an intrusion through a series of smaller alerts that are triggered (e.g., when a signature matches a known malware hash, a threshold flags an unusual spike in failed logins, or an endpoint agent detects suspicious activity). When viewed through the SIEM dashboard, an attack often begins as a series of distinct events with related or overlapping timestamps. Artificial intelligence has accelerated modern attacks, enabling attackers to automate reconnaissance, craft targeted payloads, and execute scripts in seconds. Yet, speed does not obfuscate the need for stealth. To evade detection, adversaries deliberately d...

uCreator Android Spyware Can Steal Telegram 2FA Passwords and Clone WeChat Accounts

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...

Microsoft 365 Token-Replay Attacks Compromise 97 Accounts at 79 Organizations

Cybersecurity researchers have disclosed a Microsoft 365 campaign that has been observed leveraging an adversary-in-the-middle ( AitM ) relay to capture sign-in sessions and then replay the stolen tokens to break into email accounts at 79 organizations. Huntress, which observed the activity between July 14 and September 22, 2026, said it detected 497 successful Microsoft 365 sign-in events across the victim organizations from over 200,000 login attempts, with the attackers ultimately compromising 97 accounts and registering 48 rogue Entra devices. "Rather than guessing passwords, the attacker replayed sign-in tokens stolen from victims, and we've traced more than 200,000 failed login attempts from the campaign window back to the 193.26.115[.]0/24 IP range," Huntress researchers Andrea Hatcher, Susannah Matt, Matt Poto, and Andrew Schwartz said. The attack has been found to employ an AitM login page, which sits between the victims and legitimate Microsoft infrastru...

Gheist Uses Stolen GitHub Tokens to Steal Private Repository Secrets via Actions Logs

An automated campaign is using stolen GitHub tokens to plant workflows that print a repository's secrets into its GitHub Actions logs, which the attackers then download before deleting the runs. The attacks have succeeded in private repositories and GitHub Enterprise environments, according to an analysis by cloud security company Wiz. A  GitHub safeguard  that pauses suspicious workflow runs stopped every public-repository run Wiz checked, but it does not cover private repositories or GitHub Enterprise Server. Each workflow sits on a new branch named ci-sync- followed by six random characters. Deleting a branch, or the run it started, does not undo the exposure. Every secret the repository could read should be rotated, and the token that pushed the branch revoked. Wiz has tracked the campaign since September 15 and calls it Gheist , after the user agent gheist that the attackers' tool sends with GitHub API requests. Wiz has recovered mor...

Malicious File in Downloads Folder Tries to Trick AI Coding Agent Into Installing Malware

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 ...
