🔒 Apple is urging users on older versions of iOS to update immediately after reporting that web-based exploit kits such as Coruna and DarkSword have been used to deliver data-stealing malware via compromised sites. Apple says devices running the latest releases (iOS 15 through 26) are not affected, and has released targeted patches for legacy hardware. For devices that cannot be updated, Apple recommends specific interim updates and enabling Lockdown Mode to reduce exposure.

📱 Zimperium zLabs reports a global surge in mobile banking malware targeting 1,243 financial brands across 90 countries. The firm analysed 34 active malware families affecting apps with more than three billion downloads and found industrialised campaigns exploiting weak app protections and widespread code sharing. Attacks now intercept authentication codes, hijack live sessions and can take control of devices, undermining traditional backend fraud controls.

🔒 ThreatFabric researchers disclosed a new Android banking malware family named Perseus that enables device takeover and financial fraud through dropper apps promoted on phishing and IPTV sideloading sites. Built on code from Cerberus and Phoenix, Perseus leverages Accessibility-based remote sessions to monitor, interact with, and fully control infected devices. It targets users across Turkey, Italy and other European and Middle Eastern markets, and adds note‑scanning to harvest high-value personal data. Operators can issue remote commands, stream screens, run HVNC sessions, and authorize fraudulent transactions via a command-and-control panel.

🔐 Researchers at ThreatFabric have discovered a new Android malware family called Perseus that scans user note-taking apps to steal passwords, recovery phrases, and financial data. Distributed via sideloaded IPTV-themed apps, Perseus abuses Accessibility Services to gain full remote control, capture screenshots, and deploy overlays and keyloggers. The threat uses a dropper capable of bypassing Android 13+ sideloading restrictions and performs extensive anti-analysis checks before exfiltration. Users are advised to avoid sideloading APKs, keep Play Protect enabled, and install apps only from the Google Play Store.

🔒 Researchers have dismantled the ShieldGuard crypto scam after Okta Threat Intelligence flagged the malicious browser extension in an advisory on March 17. Marketed as a wallet security tool with social promotion and token "airdrop" incentives, the extension instead harvested wallet addresses, scraped full HTML content after logins and tracked users across sessions. It used obfuscation and a custom JavaScript interpreter to evade Chrome protections and supported remote command-and-control execution. Partners removed the extension from the Chrome Web Store, disabled backend infrastructure, took down domains and blocked sign-in functionality; users are advised to limit plugins, verify sources and treat free-token offers with caution.

🔒 Darksword is a newly discovered iOS exploit kit targeting iPhones running iOS 18.4–18.6.2 and used to harvest credentials, photos, messages, and cryptocurrency wallet data. Researchers from Lookout, Google Threat Intelligence Group, and iVerify linked the framework to the actor behind the Coruna chain and say Apple has patched the exploited flaws. Victims should update to iOS 26.3.1 and consider enabling Lockdown Mode if at high risk.

🎮 Acronis TRU found hundreds of GitHub repositories posing as "free" game cheats that deliver the Vidar 2.0 infostealer, warning the true number of malicious repos could be in the thousands. Campaigns begin in game-focused Discord and Reddit communities and use PS2EXE-compiled PowerShell loaders to evade basic detections. Loaders add Windows Defender exclusions, fetch secondary payload URLs from Pastebin linking to GitHub-hosted binaries, and deploy a Themida-packed Vidar executable that establishes persistence via scheduled tasks. The payload then harvests credentials, tokens and files and exfiltrates them through C2 infrastructure masked by Telegram bots and Steam dead-drop resolvers.

🛡️ Rapid7 and Microsoft researchers have documented a ClickFix operation that compromised over 250 WordPress sites to distribute fileless infostealers using counterfeit Cloudflare CAPTCHA prompts. The injected JavaScript hides from administrators and coerces visitors into pasting obfuscated commands that launch an in-memory DoubleDonut loader, which injects payloads into legitimate Windows processes. Observed payloads include a new Vidar variant and two previously undocumented stealers—Impure Stealer (.NET) and VodkaStealer (C++)—both using advanced encoding, encryption and sandbox-detection checks. Site owners are urged to restrict public admin access, tighten credentials and apply the published IOCs and YARA rules.

🛡️ Sophos researchers identified three ClickFix campaigns that used malicious search ads and trusted-host lures to coax macOS users into pasting and executing terminal commands, resulting in the deployment of the MacSync infostealer. The campaigns—first observed in November and December 2025 and refreshed in February 2026—leveraged fake Google Sites, ChatGPT conversation redirects, and GitHub-style pages. The February variant introduced dynamic AppleScript and in-memory execution to harvest credentials, keychain data, files, and crypto seed phrases while attempting to erase traces.

🔒 Researchers warn that criminals have scaled ClickFix social-engineering lures to deliver sophisticated, fileless infostealers via compromised WordPress sites. Rapid7 observed a campaign active since December 2025 that leveraged fake Cloudflare CAPTCHA prompts across more than 250 WordPress domains in 12 countries to trick victims into running obfuscated commands. The chain deploys an in-memory loader called DoubleDonut that injects payloads into legitimate Windows processes, and analysts also observed novel .NET and C++ stealers alongside a new Vidar variant. Microsoft noted a separate campaign that pivots from the Run dialog to Windows Terminal for execution.

🎮 The FBI's Seattle Division is seeking information from gamers who installed Steam titles later found to contain malware between May 2024 and January 2026. Identified titles include BlockBlasters, Chemia, Dashverse/DashFPS, Lampy, Lunara, PirateFi, and Tokenova. The agency's questionnaire targets cryptocurrency theft and account hijacking and requests transaction details, compromised account information, and screenshots of communications to help trace stolen funds and those who distributed the malware.

🔒 Microsoft disclosed a credential-theft campaign that uses SEO poisoning to push trojanized VPN clients impersonating legitimate enterprise software. Attackers hosted ZIPs on GitHub containing MSI installers that sideload malicious DLLs and deploy a Hyrax variant, presenting a fake sign-in dialog to harvest VPN credentials. Microsoft removed the repositories and revoked the signing certificate; organizations should enable MFA and verify software sources.

🔎 Atos researchers disclosed a ClickFix variation that leverages the Run dialog to execute a 'net use' command, map a remote WebDAV share, and run a hosted batch file. The chain downloads a ZIP that unpacks a trojanized WorkFlowy Electron app whose app.asar contains an obfuscated main.js acting as a persistent C2 beacon and dropper. The campaign evaded Microsoft Defender for Endpoint and was detected through targeted hunting of RunMRU registry activity.

🔒 A threat actor tracked as Storm-2561 is distributing spoofed enterprise VPN clients impersonating vendors such as Ivanti, Cisco, and Fortinet to harvest corporate VPN credentials. The campaign uses SEO poisoning to push victims to convincing fake vendor pages that link to a GitHub-hosted ZIP containing a malicious MSI installer. When run, the installer places a fake Pulse.exe, drops a loader (dwmapi.dll) and a Hyrax infostealer variant (inspector.dll), captures credentials and configuration files, then displays an installation error and redirects victims to the legitimate vendor site to avoid immediate suspicion.

🔍 Microsoft warns that the cybercriminal group Storm-2561 is poisoning search results to distribute trojanized VPN clients that harvest corporate credentials. The campaign redirects victims to digitally signed malware hosted on GitHub and then opens legitimate vendor sites to minimize detection. The installer side-loads malicious DLLs — including a variant of the Hyrax infostealer — to extract VPN credentials and achieve persistence via the RunOnce registry key. Microsoft recommends enforcing multifactor authentication, disabling browser password syncing on managed devices, and running endpoint detection and response in block mode with network and web protections enabled.

🛡️ Brazilian cybersecurity firm ZenoX disclosed a Rust-based banking trojan named VENON that targets Windows users and 33 financial and digital-asset platforms. The threat chain uses DLL side-loading and a PowerShell-delivered ZIP to drop a malicious DLL that performs nine evasion techniques (anti-sandbox checks, indirect syscalls, ETW and AMSI bypasses) before executing payloads. VENON fetches configuration from Google Cloud Storage, installs a scheduled task, and connects to a WebSocket C2 while employing banking overlays, active window monitoring, and an Itaú-specific LNK hijack implemented via embedded VBS; it also supports a remote uninstall to restore altered shortcuts. ZenoX noted the Rust code reflects knowledge of Latin American trojans and appears to have been rewritten or expanded with the aid of generative AI.

🔒 PixRevolution is an Android banking trojan uncovered by Zimperium that silently monitors devices and redirects funds during Brazil's PIX instant payments. It abuses Android accessibility permissions to stream screens to an attacker-controlled server, detects payment activity, and replaces recipient keys while displaying a fake loading overlay. The campaign relies on an agent-in-the-loop model with human operators intervening in near real time and spreads via fraudulent download pages impersonating legitimate Brazilian apps.

🔒 Kaspersky researchers uncovered malicious Google Search ads that mimic documentation for popular AI assistants (for example, Claude Code, OpenClaw and Doubao) to trick users into running installer commands. The fake guides prompt victims to execute commands that deploy AMOS on macOS (via curl) or the Amatera infostealer on Windows (via mshta.exe), which exfiltrates browser data, crypto-wallets and files to a remote server. Organizations should warn staff, centrally manage access to AI tools and maintain endpoint protections.

🛡️Researchers report six Android malware families targeting Pix payments, banking apps, and cryptocurrency wallets. The threats — including PixRevolution, BeatBanker, TaxiSpy RAT, Mirax, Oblivion RAT, and SURXRAT — rely on fake Google Play Store pages, accessibility and MediaProjection abuse, screen overlays, and remote control to harvest credentials and hijack transfers. Campaigns use Firebase or custom TCP/9000 C2s, include miners or RAT payloads, and some samples experiment with large language model components to refine targeting.

🔒 Rapid7 has identified a widespread campaign that compromises legitimate WordPress websites to infect visitors with infostealer malware. Attackers display a convincing fake Cloudflare CAPTCHA and use the ClickFix social‑engineering trick to prompt victims to paste commands into Windows Run, initiating staged downloads. Observed payloads include Vidar, Impure, Vodka and Double Donut. Site administrators are urged to update components, enable MFA, use strong passwords and avoid executing untrusted code on credential-bearing devices.
