Researchers Use Claude to Port Pre-Auth RCE Exploit From One PLC Model to Another

Researchers Use Claude to Port Pre-Auth RCE Exploit From One PLC Model to Another

Sep 02, 2026 Vulnerability / Artificial Intelligence
Forescout Research - Vedere Labs said it used Anthropic's Claude to port a working pre-authentication remote code execution (RCE) exploit from one WAGO programmable logic controller (PLC) to another, executing attacker-supplied ARM shellcode on live hardware. The exploit targets  CVE-2021-31886 , a stack-based buffer overflow in the Nucleus FTP server's handling of the USER command, which carries a Siemens-assigned CVSS score of 9.8 and is accessible before authentication over TCP port 21. CERT@VDE says no updates are available for the affected WAGO controllers, and advises owners to disable or block FTP on port 21, enforce segmentation controls, and monitor network traffic for anomalies. The port required sustained researcher steering, and the final RCE development stage consumed $535.74 in application programming interface (API) usage over an 8-hour-32-minute session. A later session that attempted to extend the exploit into a command-and-control (C2) implant w...
Attackers Exploit Critical Switchvox Flaw to Deploy Reverse Shells Without Credentials

Attackers Exploit Critical Switchvox Flaw to Deploy Reverse Shells Without Credentials

Sep 02, 2026 Vulnerability / Network Security
Threat actors are exploiting a severe security vulnerability in Sangoma Switchvox, an enterprise VoIP platform, that could allow unauthenticated remote code execution. The vulnerability in question is CVE-2026-9586 (CVSS score: 9.3), a critical unauthenticated SQL injection vulnerability in Sangoma Switchvox SMB Edition 8.3 (104997) that can allow attackers to remotely execute arbitrary code as the PostgreSQL superuser without credentials. Sangoma released patches for the flaw in Switchvox 8.4.0.2 on July 14, 2026. "An unauthenticated SQL injection vulnerability exists in Sangoma Switchvox SMB Edition 8.3 (104997). The /pa endpoint processes XML content beginning with <PolycomIPPhone> and directly concatenates the user-controlled PhoneIP value into PostgreSQL queries without sanitization or parameterization," according to a description of the flaw on CVE.org. "An unauthenticated remote attacker can execute arbitrary SQL statements against the backend Postg...
Attackers Exploit Critical JFrog Artifactory Flaw to Mint Admin Tokens Days After Disclosure

Attackers Exploit Critical JFrog Artifactory Flaw to Mint Admin Tokens Days After Disclosure

Sep 01, 2026 Vulnerability / Supply Chain Attack
Threat actors are exploiting a newly patched critical security flaw impacting JFrog Artifactory merely days after public disclosure, according to watchTowr . The vulnerability in question is CVE-2026-82329 (CVSS score: 9.8), a case of authentication bypass that could lead to administrative access in Artifactory. "JFrog Artifactory contains an authentication weakness that, under default configuration, may allow an unauthenticated attacker with network access to obtain administrative privileges," according to a description of the flaw on CVE.org. The vulnerability was patched by JFrog with Artifactory version 7.161.20 released on August 28, 2026. It affects the following versions - 7.161.0 > 7.161.19 7.146.0 > 7.146.36 7.133.0 > 7.133.28 7.125.0 > 7.125.19 7.117.0 > 7.117.27 7.111.4 > 7.111.21 "It affects default configs, requires no auth, no user interaction," Vercel CEO Guillermo Rauch said in a post on LinkedIn. ...

13 Malicious Packagist Packages Target Unpatched iPhones to Steal Crypto Wallet Seeds

13 Malicious Packagist Packages Target Unpatched iPhones to Steal Crypto Wallet Seeds

Sep 01, 2026 Malware / Web Security
Cybersecurity researchers have identified a set of 13 malicious Composer theme packages on Packagist that are designed to inject JavaScript into Vietnamese movie and comic streaming sites that install those libraries and initiate the deployment of spyware aimed at unpatched iOS devices. "The injected code runs two operations against a site's visitors: a mobile ad-fraud and gambling-redirect chain, and, on iPhones, a WebKit-to-kernel exploit chain that installs spyware," Socket security researcher Kush Pandya said . The activity is assessed to be part of a campaign that was first documented by the application security company back in March 2026 that leveraged six malicious Packagist packages posing as OphimCMS themes to redirect visitors, exfiltrate URLs, inject ads, and serve from Funnull -hosted infrastructure a second-stage payload to lead victims to gambling and adult content sites. The complete set of packages, which span five vendor namespaces, is below - ...
Threat Actors Don’t Want Better Attacks. They Want Repeatable Ones

Threat Actors Don’t Want Better Attacks. They Want Repeatable Ones

Sep 01, 2026 Social Engineering / Endpoint Security
The most common way into a company last year was to ask. A web page tells the visitor to prove they are not a robot. While they read the instructions, it quietly places a command on their clipboard. Then it talks them through opening a terminal and pasting it in. The technique is called ClickFix, and it was the most common initial access method Microsoft’s team observed last year , accounting for 47% of the attacks in their notifications. Nothing arrives as an attachment, so there is nothing to scan. No vulnerability is used, so there is nothing to patch. What happens next is just as ordinary. When Bitdefender analyzed 700,000 security incidents , 84% of the high-severity ones involved binaries that were already on the machine - the same administrative tools your IT team uses every day. Nothing malicious was installed, because nothing malicious was needed. Neither technique is clever, but both are winning. And the reason is not that attackers have run out of ideas. It is that th...
