Software supply chain security was hard enough. Then AI joined the build pipeline. For five years, "software supply chain security" meant one question: what's in your code? Which open-source packages, which versions, which transitive dependencies three layers deep that nobody chose on purpose? SolarWinds, Log4Shell, and XZ Utils all taught the same lesson: the risk lives less in the code a team writes and more in everything that produces it. Shai-Hulud, the self-propagating malicious package campaign that spread through developer toolchains this year, taught the next one: knowing what's in your code is still necessary, but it's no longer sufficient. In the roughly 20 months since the Model Context Protocol launched, AI tools, models, and the infrastructure around them have become load-bearing parts of how software gets built, deployed, and run. Code is written by agents. Packages are pulled in by autonomous tools that decide they are needed. Prompts have...

A suspected China-aligned threat activity cluster has been observed exploiting Roundcube webmail software belonging to physics and engineering departments of U.S. and Canadian universities as part of a new campaign. The activity involves the exploitation of now-patched, critical security flaws in the open-source email solution, such as CVE-2024-42009 (CVSS score: 9.3), to siphon credentials, followed by either the deployment of a web shell for persistent access or a known post-exploitation tool called VShell . The emerging threat cluster is being tracked by Proofpoint under the moniker UNK_MassTraction . It was first detected in May 2026, specifically focusing on administrators and professors in departments with either national security ties or entities studying astrophysics and particle physics. "The emails targeting university departments used both compromised senders, as well as abused domains vulnerable to spoofing due to lax DMARC policy to send the emails," the ...

Several versions of firmware released by Chinese network device manufacturer Tenda have been found to embed an undocumented authentication backdoor that enables administrative access to the devices' web management interfaces, the CERT Coordination Center (CERT/CC) warned Monday. "An attacker can exploit this vulnerability, tracked as CVE-2026-11405 , to bypass the password verification process and obtain full administrative control without valid credentials," the CERT/CC said in an alert. The vulnerability impacts multiple versions of the firmware - US_FH1201V1.0BR_V1.2.0.14(408)_EN_TD US_W15EV1.0br_V15.11.0.5(1068_1567_841)_EN_TDE US_AC10V1.0re_V15.03.06.46_multi_TDE01 US_AC5V1.0RTL_V15.03.06.48_multi_TDE01 US_AC6V2.0RTL_V15.03.06.51_multi_T The backdoor functionality is present within the "login()" function of the "/bin/httpd" web server binary. While the method initially follows a normal authentication path using MD5-based p...

BeyondTrust has released updates to address two critical security flaws affecting Remote Support (RS) and Privileged Remote Access (PRA) products that, if successfully exploited, could allow unauthenticated attackers to take control of susceptible devices. The vulnerabilities are listed below - CVE-2026-40138 (CVSS score: 9.2) - A pre-authentication vulnerability exists in the authentication subsystem of BeyondTrust Remote Support and Privileged Remote Access stemming from improper validation of authentication data that could allow a network-positioned attacker to bypass access controls and gain unauthorized access to the appliance, including accounts with elevated privileges. CVE-2026-40139 (CVSS score: 9.2) - A pre-authentication vulnerability exists in the authentication subsystem of BeyondTrust Remote Support stemming from improper processing of authentication requests that could allow an unauthenticated remote attacker to bypass access controls and gain unauthorized ...

An Iranian hacking group affiliated with Iran's Ministry of Intelligence and Security (MOIS) has been wielding a previously undocumented modular command-and-control (C2) framework dubbed Cavern (aka Cav3rn) targeting Israeli organizations. The activity, which has primarily singled out IT providers and government sectors, has been attributed to a threat cluster tracked by Check Point Research under the moniker Cavern Manticore , which it said shares some level of tactical overlaps with MuddyWater and Lyceum , the latter of which is assessed to be a subgroup within OilRig . "The framework reflects a mature and adaptable toolset built around a shared .NET foundation, while using multiple compilation formats across different components, including .NET Framework, .NET Mixed-Mode C++/CLI, and .NET Native AOT ," the cybersecurity company said . "The compilation format itself becomes the anti-analysis layer that forces reverse engineers into multiple toolsets and me...
