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...

A TantoSec proof-of-concept turns an AES-CBC "padding oracle" in Telerik UI for ASP.NET AJAX into unauthenticated remote code execution — but only against applications in a specific non-default configuration, and Progress patched the chain in July. There are no confirmed reports of exploitation in the wild. Security firm TantoSec has published a working exploit chain targeting vulnerabilities in Telerik UI for ASP.NET AJAX that can allow an unauthenticated attacker to execute remote code on the server hosting a vulnerable application. Progress Software patched the flaws in July, and exploitation requires a non-default configuration — but the release pairs a detailed write-up with a ready-to-run tool and two payloads, putting a complete attack path in public hands for the first time. The underlying flaws are not new. Progress shipped the fix in version 2026.2.708 (2026 Q2 SP1) on July 8 and published the CVEs and advisory on July 22. What changed on September 7 is t...

Every on-premises N-central build below 2026.3.1.14 — including servers updated to Hotfix 3 a day earlier — needs Hotfix 4. N-able's incident notice says the flaw has been exploited in the wild; its release notes say that is unconfirmed. N-able has released its  fourth hotfix  in five weeks for the N-central remote monitoring and management (RMM) platform, this time for a maximum-severity vulnerability that could allow remote code execution on the N-central server without authentication. The company's own communications disagree on whether the flaw has already been exploited. The vulnerability, tracked as  CVE-2026-86218 , carries a CVSS 4.0 score of 10.0, assigned by N-able as the CVE Numbering Authority, and is classed as a static code injection weakness (CWE-96). It affects every N-central build before 2026.3.1.14, the build shipped as 2026.3 Hotfix 4 in the early hours of September 6 (UTC). That includes servers already updated to  Hotfix 3  (2026.3...

Attackers are exploiting MikroTik routers with their Secure Shell (SSH) remote-access service, which is reachable from the internet, to gain full administrative control without authentication, according to  CERT Polska's attack warning , published on September 5. Successful attacks date to at least September 2. The Hacker News’s September 6 review of the warning found no victim count or attacker identity. MikroTik's security update  lists fixed RouterOS releases. CERT says the fixes prevent the observed attacks and recommends immediate installation, followed by a check for unauthorized configuration changes. According to the  vendor's default firewall explanation , home MikroTik devices block public access to management ports while their default firewall rules remain intact. The Hacker News checked CERT's  affected RouterOS versions  against MikroTik's listed fixes on September 6. Use the  official RouterOS downloads  for your update. ...

Attackers are exploiting a new unpatched vulnerability in Magento Open Source and Adobe Commerce that lets them run malicious code on an online store's server without logging in, Dutch e-commerce security company Sansec said in an  advisory published on September 5 . Sansec, which discovered the flaw and named it StyleSmuggler , said attacks started on September 4. "Sansec is publishing early because stores are being compromised right now," the company said. As of September 6, Adobe has not published an advisory, a CVE identifier, a patch, or a workaround, and its  Adobe Commerce security bulletin index  lists nothing after the August 11 update. A successful attack gives the attacker code execution on the store's server and installs a persistent backdoor. Sansec said all current versions are affected, including 2.4.9, and that it reproduced the full unauthenticated chain on clean Magento Open Source installations of 2.4.7, 2.4.8, and 2.4.9. Its ...
