U.S. Treasury Lifts Sanctions on Three Individuals Linked to Intellexa and Predator Spyware
The U.S. Department of the Treasury's Office of Foreign Assets Control (OFAC) on Tuesday removed three individuals linked to the Intellexa Consortium, the holding company behind a commercial spyware known as Predator , from the specially designated nationals list. The names of the individuals are as follows - Merom Harpaz Andrea Nicola Constantino Hermes Gambazzi Sara Aleksandra Fayssal Hamou Hamou was sanctioned by OFAC in March 2024, and Harpaz and Gambazzi were targeted in September 2024 in connection with developing, operating, and distributing Predator. It's currently not known why they were removed from the list. Harpaz is said to be working as a manager of Intellexa S.A., while Gambazzi was identified as the owner of Thalestris Limited and Intellexa Limited. Thalestris, Treasury Department said, held the distribution rights to the spyware, and processed transactions on behalf of other entities within the Intellexa Consortium. It's also the parent company...
IBM Warns of Critical API Connect Bug Allowing Remote Authentication Bypass
IBM has disclosed details of a critical security flaw in API Connect that could allow attackers to gain remote access to the application. The vulnerability, tracked as CVE-2025-13915 , is rated 9.8 out of a maximum of 10.0 on the CVSS scoring system. It has been described as an authentication bypass flaw. "IBM API Connect could allow a remote attacker to bypass authentication mechanisms and gain unauthorized access to the application," the tech giant said in a bulletin. The shortcoming affects the following versions of IBM API Connect - 10.0.8.0 through 10.0.8.5 10.0.11.0 Customers are advised to follow the steps outlined below - Download the fix from Fix Central Extract the files: Readme.md and ibm-apiconnect-<version>-ifix.13195.tar.gz Apply the fix based on the appropriate API Connect version "Customers unable to install the interim fix should disable self-service sign-up on their Developer Portal if enabled, which will help minimise their exp...
Researchers Spot Modified Shai-Hulud Worm Testing Payload on npm Registry
Cybersecurity researchers have disclosed details of what appears to be a new strain of Shai Hulud on the npm registry with slight modifications from the previous wave observed last month. The npm package that embeds the novel Shai Hulud strain is " @vietmoney/react-big-calendar ," which was uploaded to npm back in March 2021 by a user named "hoquocdat." It was updated for the first time on December 28, 2025, to version 0.26.2. The package has been downloaded 698 times since its initial publication. The latest version has been downloaded 197 times. Aikido, which spotted the package, said it has not spotted any major spread or infections following the release of the package. "This suggests we may have caught the attackers testing their payload," security researcher Charlie Eriksen said . "The differences in the code suggests that this was obfuscated again from the original source, not modified in place. This makes it highly unlikely to be a copy-ca...
Trust Wallet Chrome Extension Hack Drains $8.5M via Shai-Hulud Supply Chain Attack
Trust Wallet on Tuesday revealed that the second iteration of the Shai-Hulud (aka Sha1-Hulud) supply chain outbreak in November 2025 was likely responsible for the hack of its Google Chrome extension, ultimately resulting in the theft of approximately $8.5 million in assets. "Our Developer GitHub secrets were exposed in the attack, which gave the attacker access to our browser extension source code and the Chrome Web Store (CWS) API key," the company said in a post-mortem published Tuesday. "The attacker obtained full CWS API access via the leaked key, allowing builds to be uploaded directly without Trust Wallet's standard release process, which requires internal approval/manual review." Subsequently, the attacker is said to have registered the domain "metrics-trustwallet[.]com" and pushed a trojanized version of the extension with a backdoor that's capable of harvesting users' wallet mnemonic phrases to the sub-domain "api.metrics-...
DarkSpectre Browser Extension Campaigns Exposed After Impacting 8.8 Million Users Worldwide
The threat actor behind two malicious browser extension campaigns, ShadyPanda and GhostPoster , has been attributed to a third attack campaign codenamed DarkSpectre that has impacted 2.2 million users of Google Chrome, Microsoft Edge, and Mozilla Firefox. The activity is assessed to be the work of a Chinese threat actor that Koi Security is tracking under the moniker DarkSpectre . In all, the campaigns have collectively affected over 8.8 million users spanning a period of more than seven years. ShadyPanda was first unmasked by the cybersecurity company earlier this month as targeting all three browser users to facilitate data theft, search query hijacking, and affiliate fraud. It has been found to affect 5.6 million users, including 1.3 newly identified victims stemming from over 100 extensions flagged as connected to the same cluster. This also includes an Edge add-on named "New Tab - Customized Dashboard" that features a logic bomb that waits for three days prior to t...
CSA Issues Alert on Critical SmarterMail Bug Allowing Remote Code Execution
The Cyber Security Agency of Singapore (CSA) has issued a bulletin warning of a maximum-severity security flaw in SmarterTools SmarterMail email software that could be exploited to achieve remote code execution. The vulnerability, tracked as CVE-2025-52691 , carries a CVSS score of 10.0. It relates to a case of arbitrary file upload that could enable code execution without requiring any authentication. "Successful exploitation of the vulnerability could allow an unauthenticated attacker to upload arbitrary files to any location on the mail server, potentially enabling remote code execution," CSA said. Vulnerabilities of this kind allow the upload of dangerous file types that are automatically processed within an application's environment. This could pave the way for code execution if the uploaded file is interpreted and executed as code, as is the case with PHP files. In a hypothetical attack scenario, a bad actor could weaponize this vulnerability to place malici...

Ubiquiti: UniFi Access setzt "Full Access"-Richtlinie in UniFi Access Version 4.1.35
Eine "spezielle" Beobachtung, auf die mich ein Blog-Leser zum 17. März 2026 hingewiesen hat. Die Lösung UniFi Access von Ubiquiti wurde vor einiger Zeit auf die Version 4.1.35 aktualisiert. Dieses Update setzt aber eine "Full Access"-Richtlinie, die allen neuen Nutzern Vollzugriff 24/7 auf alle Türen gibt. Das ist so vom Hersteller beabsichtigt, wer die Lösung einsetzt, sollte vielleicht reagieren und die Zugriffsberechtigungen kontrollieren.
