Researchers at the security firm Calif have built a worm that takes over a WeChat account via an incoming call and  demonstrated it spreading  among three test phones. The person being called does not have to answer or touch their phone for it to work, but the caller must already be one of their WeChat contacts. Calif reported the flaw to Tencent in July and says the company has since blocked the exploit for all users. No attacks using the flaw have been reported, and Calif does not say there were any. Attacks that require no action from the target, known as zero-click attacks, are not new. Last year, WhatsApp  patched a flaw  it said may have been used in targeted attacks. Answering the call does not stop the attack. Calif said a person who picks up hears nothing and the exploit still works. Declining the call ends that attempt, but the attacker can call again later, for example while the target is asleep. The caller has to be on the target's WeChat contac...

A flaw in FreeIPA lets a client that has never logged in create a Kerberos identity of its own choosing in the directory and end up in the administrators group, Red Hat says. FreeIPA is the system that determines who may log in across a Linux domain and maintains all identities in a 389 Directory Server database accessed via LDAP. The attack needs a second flaw in that database software. The FreeIPA project has already fixed its side in  version 4.13.4 . Red Hat says it reproduced the chain twice on a default installation, most recently on a machine with no access at all. Red Hat tracks the FreeIPA flaw as  CVE-2026-76578  and rates it critical, with a CVSS score of 9.8. The same page says that score is preliminary and subject to review. Red Hat ships FreeIPA as its Identity Management product , where the package is called  ipa . FreeIPA ships an access control rule, called an ACI, that lets a user manage their own one-time-password token. The rule does no...

Adobe on Monday released security patches to address a maximum-severity flaw impacting Adobe Commerce and Magento Open Source that has come under active exploitation in the wild. The vulnerability, now tracked as CVE-2026-75650 (CVSS score: 10.0), has been codenamed StyleSmuggler by Sansec, which discovered zero-day exploitation starting September 4, 2026. "This update resolves a critical vulnerability that could result in arbitrary code execution," Adobe said , adding it's "aware that CVE-2026-75650 has been exploited in the wild targeting Adobe Commerce merchants." At its core, the flaw abuses Magento's template system through PHP code injection to generate a "Payment Transaction Failed Reminder" email, triggering code execution in the process.

Turning off email images should at least stop the pictures. This week, attackers had a workaround: a scannable QR code built out of text. It still appears, even with images blocked. A small detail, but an annoying one if that was a precaution you were counting on. Elsewhere, a trusted software source delivered code that stole credentials, and a protocol designed for secure network management gave outsiders useful clues before login. Add active attacks on browsers, routers, and online stores, and there’s plenty to check—even for teams that have kept up with the patches. Read the full recap for the week’s major developments, plus more research, attacks, and security news beyond what we covered last week. ⚡ Threat of the Week N-able Patches Critical N-central Flaws — N-able has released hotfixes to address two severe N-central flaws (CVE-2026-86206 and CVE-2026-86207) that could allow an unauthorized party to bypass authentication controls and gain full access to the platform. ...

Cybersecurity researchers have disclosed details of worm-like activity that abuses ConnectWise ScreenConnect to distribute a malicious Visual Basic Script (VBScript) payload to newly connected systems. According to Huntress , three unrelated incidents have been found to use diverse initial access methods, namely a Quick Assist tech-support scam, a phishing-delivered MSI installer, and a fake Geek Squad refund form lure, to activate a four-stage VBScript chain that leads to rogue ScreenConnect installations. However, once the ScreenConnect instances were installed, the cybersecurity company said it observed the clients repeatedly spawning "wscript.exe" to execute VBScripts named 1.vbs, 2.vbs, 3.vbs, and 4.vbs. The incidents were observed in August 2026. The details of the three attacks are below - A social engineering attack that persuaded a user into executing Quick Assist as part of a tech support scam, after which a rogue ScreenConnect remote access client was d...
