Microsoft adds Windows protections for malicious Remote Desktop files

Microsoft has introduced new security measures for Windows 10 and Windows 11 to protect against phishing attacks that exploit Remote Desktop Protocol (RDP) connection files. These updates, part of the April 2026 cumulative updates (KB5082200, KB5083769, and KB5082052), include a one-time educational prompt for users upon first opening an RDP file, requiring acknowledgment of the associated risks. Subsequent attempts to open RDP files will display a security dialog with information about the file's publisher, the remote system address, and local resource redirections, with options disabled by default. If an RDP file is unsigned, a warning will indicate an "Unknown remote connection." These protections apply only to connections initiated through RDP files, not through the Windows Remote Desktop client, and can be temporarily disabled via the Windows Registry.

Security researchers find 213 vulnerabilities in Russia’s state-backed messaging app Max

Security researchers discovered 213 vulnerabilities in Max, Russia's state-backed messaging app, during a bug bounty initiative. This information was shared by Alexei Batyuk, CTO of Positive Technologies, at the Svyaz-2026 exhibition. The bug bounty program has been active since July 1, 2025, resulting in 288 accepted vulnerability reports and total payouts of nearly 22 million rubles. Common vulnerabilities could allow unauthorized access to user data through the manipulation of object identifiers. Max's press service claimed that user data is "reliably protected" and emphasized the importance of independent white-hat hackers in identifying vulnerabilities. Max was launched by VK in March 2025 and is being promoted by Russian authorities amid efforts to block other messaging platforms like Telegram and WhatsApp. The app has faced criticisms regarding user surveillance and security vulnerabilities.

NCSC warns of messaging app targeting by Russia-linked actors

The UK National Cyber Security Centre (NCSC) has warned of an increase in cyber threats from Russia-based actors, targeting high-risk individuals through messaging applications like WhatsApp, Signal, and Messenger. These threats involve deceptive tactics such as coaxing users for login codes, unauthorized device access, group chat infiltration, impersonation of trusted contacts, and phishing links. The targeting is linked to state-affiliated groups from Russia, China, and Iran. High-risk individuals are those with access to sensitive information or influential roles. The NCSC recommends several protective measures: enabling two-step verification, not sharing verification codes, monitoring linked devices, being cautious with unknown contacts, limiting personal app use for work, and using disappearing messages to reduce data exposure.

Bogus Avast website fakes virus scan, installs Venom Stealer instead

A deceptive website impersonating Avast antivirus tricks users into downloading Venom Stealer malware, which steals passwords, session cookies, and cryptocurrency wallet information. The site conducts a fake virus scan, falsely reporting threats to encourage users to download a malicious file named Avastsystemcleaner.exe. This file mimics legitimate software and operates stealthily, targeting web browsers to harvest credentials and session cookies. It also captures screenshots and sends stolen data to the command-and-control domain app-metrics-cdn[.]com via unencrypted HTTP. The malware employs evasion techniques to avoid detection and is part of a long-standing cybercrime tactic that exploits user trust in security software. Indicators of compromise include the file hash SHA-256: ecbeaa13921dbad8028d29534c3878503f45a82a09cf27857fa4335bd1c9286d, the domain app-metrics-cdn[.]com, and the network indicator 104.21.14.89.

FBI warns of Russian, Iranian cyber activity involving messaging platforms

The FBI issued alerts regarding cyber campaigns by Russian and Iranian actors targeting messaging platforms. Russian intelligence services are reportedly infiltrating applications like Signal, leading to unauthorized access of thousands of accounts of U.S. government officials, military personnel, political figures, and journalists. Russian operatives are using phishing messages disguised as support notifications to trick users into providing verification codes or account PINs, potentially allowing attackers to take over accounts. Once compromised, attackers can access messages, contact lists, and launch further phishing attempts. The advisory emphasizes that while Signal is targeted, similar tactics can affect any messaging app. In a separate alert, the FBI highlighted Iran’s Ministry of Intelligence and Security (MOIS) using Telegram to distribute malware aimed at Iranian dissidents and journalists, enabling them to steal sensitive information. This malware often disguises itself as legitimate software and connects to Telegram bots for remote access and data exfiltration. The FBI linked these activities to the Handala Hack group, which claimed responsibility for a recent attack on medical device manufacturer Stryker. The malware can be introduced through social media by hackers posing as technical support. Experts note that the use of Telegram for cyber compromises is increasing, as it helps malicious actors avoid detection by blending their traffic with trusted platforms.
