A PDF reader with 50,000 downloads turned out to be anything but harmless. The Anatsa banking trojan slipped back into Google Play, targeting North American users with fake maintenance screens while logging keystrokes and automating fraudulent transactions. However, the app has been pulled by Google. This month’s Patch Tuesday came with a hefty payload. Microsoft released fixes for 137 vulnerabilities, including a zero-day in SQL Server, which allowed access to uninitialized memory. Among the 14 critical issues were remote code execution bugs in SharePoint and multiple RCE and side-channel flaws affecting AMD-based systems. When a tap does more than you think, it’s probably TapTrap. Researchers have uncovered a sneaky Android exploit that uses near-invisible UI animations to trick users into approving sensitive actions.

There’s a reason that app never showed up on your home screen. The IconAds fraud operation used 352 hidden-UI apps to flood ad networks with over a billion fake bid requests daily. Kaleidoscope took it further, using decoy apps to mask malicious versions distributed via third-party stores. Meanwhile, NGate and Ghost Tap abused NFC to enable remote cash theft, and Qwizzserial posed as a government app in Uzbekistan. When routers fall, botnets rise. RondoDox is exploiting flaws in TBK DVRs and Four-Faith routers to install a Linux-based botnet that renames critical system files into nonsense strings, effectively crippling recovery efforts. It launches DDoS attacks through spoofed traffic that looks like OpenVPN or online games, making detection even harder. Sometimes, all it takes is a single misplaced HTTP header. Three critical vulnerabilities in Apache Tomcat and Camel are under active exploitation, enabling remote code execution. One stems from mishandling PUT requests; the others from flawed case handling in headers. Over 125,000 attempts were recorded in March alone, signaling widespread attacker interest.

Two different names - same tactics, same tools, same playbook. Researchers have found striking overlaps between TA829 and the lesser-known UNK_GreenSec, both of which use phishing lures and REM Proxy services through compromised MikroTik routers. Victims are redirected from fake Google Drive or OneDrive pages to payloads like RomCom RAT, Metasploit, and Morpheus ransomware. They look like wallet helpers, but they’re after everything inside. More than 40 malicious Firefox extensions have been caught stealing seed phrases and wallet keys from unsuspecting crypto users. Masquerading as MetaMask, Coinbase, and Trust Wallet, these clones use tampered open-source code, fake five-star reviews, and slick branding to blend in. A single HTTP request is all it takes to bring the server down. A critical bug in Wing FTP Server allows unauthenticated remote code execution via the login confirmation endpoint. The flaw lets attackers inject Lua code into session files, enabling total takeover, even as root or SYSTEM. It affects all versions up to 7.4.3, with a fix issued in 7.4.4.

It starts with what looks like an official message from the Colombian government. Behind it is a phishing campaign delivering DCRAT, a modular remote access tool designed for theft and system control. The attack chain begins with a ZIP file containing a VBS script that downloads an obfuscated payload. DCRAT uses steganography, multi-stage execution, and evasion techniques to dig in and stay hidden, while quietly stealing data and manipulating infected systems. That Zoom update request on Telegram? It could be a trap. North Korean actors are deploying NimDoor malware to infiltrate Web3 and crypto platforms using social engineering via Telegram. Victims are tricked into running a fake AppleScript update that launches Nim-compiled binaries with advanced techniques like signal-based persistence, process injection, and encrypted WebSocket communication. It only takes one crafted page to turn a browser into a backdoor. Google has patched CVE-2025-6554, a critical zero-day in Chrome’s V8 engine that was exploited in the wild to execute arbitrary code. The flaw, caused by a type confusion bug, may have been used in targeted attacks. Users across Windows, macOS, and Linux are urged to update immediately.

A familiar package name could be hiding far more than useful code. North Korean actors behind the Contagious Interview campaign have published 35 malicious npm packages, including keyloggers and multi-stage malware loaders like HexEval and InvisibleFerret. By mimicking popular libraries, they’ve tricked thousands of developers into pulling in backdoors designed for cross-platform surveillance. Search results for AI tools are leading users straight into malware traps. Researchers uncovered a campaign that abuses SEO tactics to rank malicious sites for AI-related queries. These sites distribute payloads like Vidar Stealer and Lumma, wrapped in deceptive installers and ZIP files, while using obfuscation techniques like XOR encryption and browser fingerprinting to stay hidden. Even AI model frameworks aren’t immune to critical flaws. NVIDIA has patched two vulnerabilities in its Megatron-LM framework that could allow attackers to inject code or escalate privileges. The bugs, affecting the Python component, pose a serious risk to model integrity and data security if left unpatched.
