Threat researchers reported active cryptocurrency-focused malware campaigns that rely on social engineering and deceptive executables to steal funds or wallet-related secrets. One operation observed by CloudSEK targets Discord communities tied to gaming, gambling, and crypto streaming, where an actor tracked as “RedLineCyber” builds trust and privately shares Windows executables (e.g., Pro.exe, peeek.exe) pitched as streaming/security tools. After installation, the malware performs clipboard hijacking, monitoring for copied wallet addresses and swapping them with attacker-controlled addresses at paste time, enabling theft with minimal user-visible indicators and limited/no obvious command-and-control activity.
Separately, Iru researcher Calvin So documented MonetaStealer on macOS, delivered as Portfolio_Review.exe but actually an unsigned Mach-O binary using a misleading .exe extension to exploit the assumption that Windows executables are harmless on Macs. The sample is Python-based and bundled with PyInstaller, with core logic hidden in a compressed portfolio_app.pyc, and was reported as having zero detections on VirusTotal at the time of analysis. MonetaStealer is designed to steal cryptocurrency wallet data along with browser secrets and Keychain information, and appears to be early-stage malware with indications of AI-assisted code structure.

4 events from the most recent confirmed update back to the earliest known activity.
Researchers reported that the Python/PyInstaller malware persistently monitored victims' clipboards and swapped copied cryptocurrency wallet addresses with attacker-controlled ones at paste time. Blockchain tracing tied the operation to theft involving Bitcoin, Ethereum, Solana, Dogecoin, Litecoin, and Tron.
CloudSEK analysts linked a cryptocurrency clipboard-hijacking campaign targeting gamers and streamers on Discord to a threat actor tracked as "RedLineCyber" using a fake "RedLine Solutions" persona. The actor reportedly built trust in gaming, gambling, and crypto-streaming communities before sending malicious Windows executables such as Pro.exe and peeek.exe.
In the same investigation, Iru identified a second Windows-labeled variant designed to display a fake portfolio interface via Tkinter. The sample reportedly contained dead logic and placeholders and did not successfully run.
Researchers at Iru reported a new macOS infostealer dubbed MonetaStealer, distributed as a fake .exe file named "Portfolio_Review.exe" that is actually an unsigned Mach-O binary. The malware targets Chrome data, cryptocurrency wallets, Keychain contents, and Wi‑Fi credentials on macOS.

Multiple reports describe **active malware campaigns targeting Windows users** with a focus on **credential, session, and wallet theft** delivered through social engineering and abuse of legitimate services. **CharlieKirk Grabber**, a Python infostealer packaged with *PyInstaller*, is distributed via phishing, cracked software, cheats, and social-media lures; it kills browser processes (via `TASKKILL`) to access credential stores, collects passwords/cookies/autofill/Wi‑Fi data, zips the loot, uploads it to *GoFile*, and relays the download link to operators via **Discord webhooks** or **Telegram bots**. Separately, attackers are buying **Facebook ads** impersonating Microsoft to drive victims to cloned Windows 11 download pages on lookalike domains (e.g., `ms-25h2-update[.]pro`), delivering a malicious installer that steals saved passwords, browser sessions, and **cryptocurrency wallet** data; the campaign uses **geofencing/sandbox evasion** to show benign content to data-center IPs while serving malware to likely end users. Other contemporaneous activity highlights broader Windows-targeted intrusion tradecraft and adjacent threats. FortiGuard Labs reported **Winos 4.0 (ValleyRat)** phishing campaigns in Taiwan using tax and e-invoice lures, with delivery chains including malicious **LNK** downloaders, **DLL sideloading**, and **BYOVD** using the vulnerable driver `wsftprm.sys`, supported by rapidly rotating domains and cloud hosting. In LATAM, a fake bank-receipt lure delivers **XWorm v5.6** via a `.pdf.js` double-extension WSH dropper that uses junk-padding and Unicode obfuscation, then reconstructs and runs PowerShell (spawned via WMI) and abuses trusted hosting (e.g., Cloudinary) for later stages—enabling credential theft and potential ransomware follow-on. Additional reporting covered a USB-propagating **Monero cryptomining** operation capable of crossing air-gapped environments, a new Linux **SysUpdate** variant with encrypted C2 traffic (and a Unicorn Engine-based decryption approach developed during DFIR), and the **Foxveil** loader abusing **Cloudflare Pages, Netlify, and Discord** to stage shellcode and persist via services or *SysWOW64* masquerading—these are separate threats but reinforce the trend of attackers blending into trusted infrastructure and common user workflows.

Researchers documented several malware campaigns that used fake software and trojanized packages to deliver credential theft and remote-access payloads. On Windows, a fake *Resident Evil 9* mod from GitHub triggered a `curl | cmd` chain that deployed hidden batch, JavaScript, portable Node.js, portable Python, and an in-memory Go payload with browser theft, wallet targeting, hVNC-style control, webcam-related code, and exfiltration via Wormhole/B2 and Gofile; a separate fake AI video player installer led through Python bytecode, shellcode, and protected .NET loaders to **PureRAT**, which persisted through the `Run` key and communicated over authenticated WebSockets with `agent.sm-veo.com`. Another Windows campaign, dubbed **Operation TURB00**, used a Go loader and decoy console program to launch **Vidar** in memory, steal browser and application data, and install persistence through `agt.dll` and the `CadenceOptimizer` service running under `svchost` as `LocalSystem`. On macOS, analysts reversed a fully undetected **Atomic macOS Stealer (AMOS)** sample distributed as a signed DMG, bypassed its anti-VM checks, and recovered an AppleScript payload that stole browser data, wallet files, Telegram Desktop data, documents, and system information before exfiltrating to `95.164.53.3/contact`. In the software supply chain, a malicious PyPI package, `nhmpy 2.4.7`, masqueraded as NumPy while using a `.pth` file and an obfuscated JavaScript payload executed through Bun to harvest developer, cloud, CI/CD, registry, SSH, wallet, messaging, VPN, and AI-assistant secrets; it then spread using stolen GitHub tokens and malicious GitHub Actions workflows. Separately, a public Windows local privilege escalation exploit named **REDSUN** showed how attackers could turn standard-user access into `NT AUTHORITY\SYSTEM` by abusing a TOCTOU flaw involving NTFS and the Cloud Files API, creating a potential post-compromise path for malware already running on a host.

Threat researchers reported two large malware distribution operations that relied on popular consumer lures rather than software exploits. One campaign used piracy sites offering movies, TV shows, books, and digital library content to push fake plugin or browser update prompts; the downloaded ZIP files abused DLL side-loading, ROP-based decryption, and reflective loading to install a modified `SilentCryptoMiner`, a watchdog, a RAT component, and CPU/GPU miners. The malware gated execution through DNS tunneling and date-generated command-and-control infrastructure, harvested host data, and established persistence with a fake `GoogleUpdateTaskMachineQC` service and repeated UAC elevation attempts, with implicated sites drawing roughly 40 million visits in a single month. A separate operation used `openew[.]app`, a fake ChatGPT download page impersonating OpenAI, to infect both Windows and macOS users with platform-specific malware. Windows visitors received a credential-stealing loader disguised as `Chat_GPT.exe`, built with Inno Setup and Electron and launching PowerShell activity that contacted `188.137.246.189`, while macOS users were served **Atomic Stealer (AMOS)** to steal passwords, browser data, Telegram sessions, and cryptocurrency wallet information. Researchers said the macOS payload also attempted to replace legitimate Ledger and Trezor applications with trojanized versions, underscoring a strong cryptocurrency theft motive and showing how attackers are exploiting AI-brand search traffic and piracy demand to scale malware infections.
