Hackers Weaponize Windows Flaw to Deploy Crypto-Siphoning Phemedrone Stealer

Hackers Weaponize Windows Flaw to Deploy Crypto-Siphoning Phemedrone Stealer

Jan 16, 2024 Cryptocurrency / Windows Security
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 Evolving Tactics of Vidar Stealer: From Phishing Emails to Social Media

The Evolving Tactics of Vidar Stealer: From Phishing Emails to Social Media

Jan 05, 2023 Data Security / Malware
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
SaaS Compliance through the NIST Cybersecurity Framework

SaaS Compliance through the NIST Cybersecurity Framework

Feb 20, 2024Cybersecurity Framework / SaaS Security
The US National Institute of Standards and Technology (NIST) cybersecurity framework is one of the world's most important guidelines for securing networks. It can be applied to any number of applications, including SaaS.  One of the challenges facing those tasked with securing SaaS applications is the different settings found in each application. It makes it difficult to develop a configuration policy that will apply to an HR app that manages employees, a marketing app that manages content, and an R&D app that manages software versions, all while aligning with NIST compliance standards.  However, there are several settings that can be applied to nearly every app in the SaaS stack. In this article, we'll explore some universal configurations, explain why they are important, and guide you in setting them in a way that improves your SaaS apps' security posture.  Start with Admins Role-based access control (RBAC) is a key to NIST adherence and should be applied to every SaaS a
