🔒 A new Android banking trojan called Massiv is being distributed as a fake IPTV application to harvest credentials, perform keylogging, and seize remote control of infected devices. Researchers at ThreatFabric observed campaigns that targeted a Portuguese government app integrated with Chave Móvel Digital, enabling fraudsters to bypass KYC checks and open accounts in victims' names. Massiv supports live screen streaming via Android's MediaProjection API and a UI-tree mode using the Accessibility Service to extract interface elements, click controls, and bypass screen-capture protections.

🛡️ Acronis Threat Research Unit disclosed CRESCENTHARVEST, a campaign observed after January 9 that targets Farsi-speaking supporters of Iran's protests with a remote access trojan and information stealer. Attackers lure victims with protest-themed archives and double-extension .LNK shortcuts that run PowerShell to fetch a secondary ZIP while opening benign media. The payload sideloads DLLs via a Google-signed software_reporter_tool.exe, extracts Chrome app-bound keys, harvests browser and Telegram data, logs keystrokes, and communicates with a WinHTTP C2 at servicelog-information[.]com.

🔍 A security researcher using the pseudonym Q Continuum discovered 287 Chrome extensions that send users' browsing history and related metadata to remote servers. The investigator ran an automated pipeline that launched Chrome in Docker, installed extensions, visited test sites, and captured outgoing traffic to reveal risky behavior across VPNs, proxy tools, coupon and PDF add‑ons, and browser utilities. Many extensions request broad cross‑site host permissions and transmit data in obfuscated or encrypted formats (Base64, ROT47, LZ‑String, even AES‑256 wrapped in RSA‑OAEP), which makes detection harder and can enable corporate espionage or credential harvesting when cookies are included.

📱 ZeroDayRAT is a commercially marketed, cross-platform spyware toolkit distributed openly via Telegram that targets Android and iOS devices. iVerify traced initial activity to 2 February and found the offering includes an APK for Android, an iOS payload, a web-based management panel, documentation, and customer support channels. The malware harvests messages, call logs, contacts, location, photos, files, notifications, and enumerates accounts across popular services, enabling sustained surveillance and potential financial theft. Infection relies on social engineering—sideloading or iOS provisioning profiles—so iVerify recommends mobile EDR, stricter controls on unauthorized installs, and detection across BYOD and managed fleets.

🔐 Security researchers have documented an infostealer attack that exposed sensitive files from local AI assistants, specifically OpenClaw. Hudson Rock reported the malware harvested configuration and key material—including openclaw.json, device.json, and agent memory files—allowing token theft, private key access, and capture of users' operational context. The incident underscores risks from plaintext secrets and permissive defaults in agentic tools.

🔓 Hudson Rock says an info‑stealer, likely a Vidar variant, exfiltrated an OpenClaw agent's configuration, including openclaw.json, device.json and soul.md. The files contain gateway tokens, cryptographic keys and the agent's operational 'soul,' which could let attackers impersonate the AI assistant or connect to local instances if exposed. The incident signals a shift from stealing credentials to harvesting AI agent identities, and vendors should expect targeted modules to follow.

🔐 Hudson Rock has observed information-stealing malware exfiltrating configuration and memory files from the OpenClaw agent framework, exposing API tokens, private keys, and persistent agent memory. The activity, attributed to a Vidar-like infostealer and recorded on 13 February 2026, captured openclaw.json, device.json, and agent 'soul' and memory files. With these items an attacker could impersonate the device, bypass Safe Device checks, access encrypted logs, or fully compromise a user's digital identity. Organizations should audit agent directories, apply vendor fixes, and enforce strict filesystem permissions immediately.

🔒 CTM360 reports attackers are abusing Google Groups and Google-hosted redirectors to distribute credential-stealing malware, leveraging over 4,000 malicious groups and 3,500 hosted URLs to target organizations worldwide. The campaign uses industry-focused posts and shortened or Docs/Drive redirect links to lure victims and deliver OS-specific payloads. On Windows, victims receive a padded archive that reconstructs an AutoIt-based loader and a memory-resident Lumma infostealer; on Linux, users are served a trojanized Chromium-branded "Ninja Browser" with covert extensions and silent persistence. CTM360 advises inspecting redirect chains, blocking IoCs, auditing browser extensions, and monitoring scheduled tasks and endpoint activity.

⚠️ Threat actors are abusing public Claude artifacts and manipulated Google Search results to trick macOS users into running malicious Terminal commands. These commands download and execute a loader that installs the MacSync infostealer, which harvests keychain data, browser credentials, and crypto wallets, then exfiltrates the data to a hardcoded command-and-control server. Researchers warn users not to run unverified shell commands and to verify safety before executing them.

🔒 Researchers uncovered multiple malicious Chrome extensions that exfiltrate sensitive data from business and social media accounts, including a Meta‑focused add‑on named CL Suite that steals TOTP seeds, one‑time codes and Business Manager exports. Other campaigns detailed include a large‑scale VK Styles hijack of VKontakte accounts and the AiFrame cluster of AI‑themed add‑ons that siphon emails and page content. A Q Continuum study also found hundreds of extensions leaking browsing history to data brokers. Experts recommend strict extension controls, frequent audits, and allowlisting to reduce risk.

🔒 Flare and other researchers describe the AMOS macOS infostealer and its use of AI-focused distribution channels to harvest credentials and crypto data. Recent ClawHavoc activity shows attackers poisoning the popular OpenClaw skill marketplace to bundle AMOS into seemingly legitimate add-ons. Campaigns also abused search-engine SEO, fraudulent GitHub repositories, and one-line Terminal installers, enabling rapid credential and session theft at scale.

⚠️ Researchers at LayerX uncovered a campaign of 30 malicious Chrome extensions, installed by more than 300,000 users, that masquerade as AI assistants while exfiltrating credentials, email content, and browsing data. The add-ons render remote content in full-screen iframes from a single domain (tapnetic.pro), letting operators change behavior without store updates. Fifteen extensions specifically inject into Gmail, reading visible thread text (including drafts) and sending it off-device, and several implement voice transcription via the Web Speech API. Users should review LayerX indicators of compromise and reset passwords if they suspect exposure.

🛡️ Bitdefender has identified a sharp increase in LummaStealer infections driven by social‑engineering campaigns that use the ClickFix clipboard trick to deliver the CastleLoader malware. CastleLoader is a heavily obfuscated, script‑based loader that decrypts and executes payloads in memory while adapting persistence and file paths to evade detection. Researchers note a characteristic failed DNS lookup artifact that can aid detection and recommend avoiding pirated or untrusted software and never running PowerShell commands provided by web pages.

🔒 A fake 7-Zip website (7zip[.]com) distributes a trojanized installer that installs the legitimate archiver along with proxyware that enrolls infected hosts as residential proxy nodes. The installer drops Uphero.exe, hero.exe and hero.dll, creates a SYSTEM service and modifies firewall rules. Malwarebytes found C2 domains using Cloudflare, TLS and DoH, and recommends obtaining software from official sites instead of following links from videos or search ads.

📱 ZeroDayRAT is a newly documented cross-platform mobile spyware operation targeting Android and iOS, according to iVerify. The toolkit grants persistent access to messages, precise GPS history, notifications, camera, microphone and keystroke capture, and exposes a dedicated web dashboard for rapid device profiling. Infections are commonly initiated via smishing, counterfeit app stores, phishing emails and links shared through messaging apps.

🔐 ZeroDayRAT is a commercial mobile spyware being sold on Telegram that grants attackers comprehensive remote control over Android (5–16) and iOS (up to 26) devices. The toolkit provides a management panel displaying device metadata and supports data theft, live audio/video capture, location tracking, SMS interception for OTPs, keylogging, and modules targeting cryptocurrency wallets and banking apps. iVerify warns it can enable enterprise breaches if employee devices are compromised and advises installing apps only from official stores and enabling protections such as Lockdown Mode on iOS and Advanced Protection on Android.

⚠ Microsoft warns that information-stealing campaigns are expanding beyond Windows to target Apple macOS by leveraging cross-platform languages like Python and abusing trusted distribution platforms. Since late 2025, attackers have used malvertising and Google Ads to redirect users to fake sites that employ ClickFix lures and DMG installers to deploy families such as Atomic macOS Stealer (AMOS), MacSync, and DigitStealer. Campaigns use fileless execution, native macOS utilities, and AppleScript to harvest browser credentials, session cookies, iCloud Keychain items, and developer secrets. Organizations are urged to train users on malvertising and fake installers, monitor Terminal and iCloud Keychain access, and inspect network egress for POSTs to newly registered or suspicious domains.

⚠️ Security researcher Paul McCarty (aka 6mile) has identified 386 malicious OpenClaw "skills" on the ClawHub repository that impersonate crypto trading tools. The add-ons use social engineering to trick users into executing commands that deploy infostealers on macOS and Windows, harvesting exchange API keys, wallet private keys, SSH credentials and browser passwords. The discovered skills share a common C2 IP (91.92.242.30) and many remain available, with the most active uploader accounting for nearly 7,000 downloads.

🐛 A new GlassWorm campaign distributed through compromised OpenVSX extensions is targeting macOS systems to steal passwords, crypto-wallet data, and developer credentials and configurations. Malicious updates pushed from the hijacked oorzc account on January 30 trojanized four packages with roughly 22,000 cumulative downloads and established persistence via a LaunchAgent while excluding Russian-locale systems. Socket's analysis shows broad data collection across browsers, wallets, macOS Keychain, Apple Notes, developer secrets, and exfiltration to 45.32.150[.]251; affected releases were removed and tokens revoked, but users are advised to perform full system clean-up and rotate secrets.

🛡️ Microsoft Defender Experts report a cross-platform surge in infostealers that now target macOS, leverage Python toolchains, and abuse trusted platforms and utilities to deliver credential-stealing malware at scale. Since late 2025, macOS campaigns such as DigitStealer, MacSync, and AMOS have used social engineering, malicious DMGs, AppleScript, and fileless execution to harvest browser credentials, keychain secrets, developer keys, and crypto wallets. Phishing campaigns have delivered Python-based stealers like PXA Stealer, while platform-abuse activity has weaponized WhatsApp and fake PDF installers to propagate Eternidade Stealer and malicious Crystal PDF installers. Microsoft outlines Defender XDR detections, hunting queries, and mitigations to help organizations detect, contain, and remediate these evolving threats.
