🔍 Kaspersky researchers analyzed a short-lived information stealer called Arkanix, promoted on dark web forums in late 2025 and likely developed with LLM assistance. The project included a control panel, a Discord community, and two tiers: a Python-based basic build and a VMProtect-wrapped C++ premium variant with enhanced AV evasion and wallet injection. Arkanix features modular data theft from browsers, wallets, Telegram and Discord, plus optional post-exploitation modules; the author removed infrastructure within two months, complicating detection and tracking.

🛡️ ESET researcher Lukas Stefanko has identified PromptSpy, the first known Android malware to call a generative AI model at runtime, leveraging Google's Gemini to adapt persistence on different devices. The malware submits an XML dump of the current UI plus a chat prompt to Gemini, receives JSON-formatted instructions, and uses the Accessibility Service to pin the app in Recent Apps in a loop until confirmed. Its primary payload is a VNC-based spyware module that can capture PINs, record unlock patterns and screen activity, take screenshots, and report foreground apps. To block removal it overlays invisible UI elements over uninstall or permission controls; victims must reboot into Safe Mode to remove it.

🛡️ ESET researchers disclosed PromptSpy, the first Android malware observed to integrate Google's Gemini generative AI into its execution flow and achieve persistence. The malware assigns Gemini the persona of an 'Android automation assistant,' sends an XML dump of the current screen, and receives JSON step-by-step instructions that are executed via accessibility services. PromptSpy captures lockscreen data, records screens and video, deploys a VNC module for remote access, and blocks uninstallation using invisible overlays while communicating with a hard-coded C2.

🔍 Group-IB uncovered a sophisticated campaign that impersonated Indonesia’s official Coretax service to distribute malicious Android APKs, causing an estimated $1.5m–$2m in losses nationwide. Attackers combined phishing sites, WhatsApp impersonation and vishing to coerce victims into installing RATs such as Gigabud.RAT and MMRat, enabling remote access and unauthorized banking transfers. The operation produced 996 phishing URLs, 228 new malware samples and used infrastructure that impersonated over 16 trusted brands, suggesting a scalable MaaS model.

🔐Modern infostealers harvest credentials, session data, cookies, and local files, turning a single compromise into a persistent identity asset. Specops researchers analyzed over 90,000 infostealer dumps and more than 800 million rows, showing how disparate signals tie accounts, employers, and roles to real people. By blocking known-compromised passwords across Active Directory, Specops Password Policy aims to reduce reuse and downstream enterprise risk.

🔒 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.
