Threat actors have been observed leveraging a now-patched security flaw in Microsoft Windows to deploy an open-source information stealer called  Phemedrone Stealer . "Phemedrone targets web browsers and data from cryptocurrency wallets and messaging apps such as Telegram, Steam, and Discord," Trend Micro researchers Peter Girnus, Aliakbar Zahravi, and Simon Zuckerbraun  said . "It also takes screenshots and gathers system information regarding hardware, location, and operating system details. The stolen data is then sent to the attackers via Telegram or their command-and-control (C&C) server." The attacks leverage  CVE-2023-36025  (CVSS score: 8.8), a security bypass vulnerability in Windows SmartScreen, that could be exploited by tricking a user into clicking on a specially crafted Internet Shortcut (.URL) or a hyperlink pointing to an Internet Shortcut file. The actively-exploited shortcoming was  addressed  by Microsoft as part of its November 2023 Patch Tuesday updates.

The notorious information-stealer known as  Vidar  is continuing to leverage popular social media services such as TikTok, Telegram, Steam, and Mastodon as an intermediate command-and-control (C2) server. "When a user creates an account on an online platform, a unique account page that can be accessed by anyone is generated," AhnLab Security Emergency Response Center (ASEC) disclosed in a technical analysis  published  late last month. "Threat actors write identifying characters and the C2 address in parts of this page." In other words, the technique relies on actor-controlled throwaway accounts created on social media to retrieve the C2 address. An advantage to this approach is that should the C2 server be taken down or blocked, the adversary can trivially get around the restrictions by setting up a new server and editing the account pages to allow the previously distributed malware to communicate with the server. Vidar, first identified in 2018, is a  commer

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,
