PAPERMILL Hackers Abuse Signed Notepad++ to Deploy VenomRAT in Tax Audit Attacks

PAPERMILL phishing campaign abuses a signed Notepad++ copy and tax-audit lures to deploy VenomRAT against targets in India.

JUMPSEC tracks PAPERMILL as an emerging cluster whose emails pass SPF, DKIM, and DMARC and deliver tax-audit themed disk images. The mounted image pairs a legitimately signed, renamed executable with a rogue libcurl.dll for DLL sideloading, then uses a Donut shellcode loader to run VenomRAT 6.0.3 in memory with hidden VNC, data-stealing, and file-grabbing capabilities. The loader includes anti-analysis checks and RunOnce persistence, and lures plus China-connected infrastructure overlap with the Silver Fox ecosystem, though attribution remains unconfirmed.

Fake AI trading agent steals crypto wallet passwords

Fake AI crypto trading agent sites deliver Needle Stealer, which replaces browser wallet extensions to steal wallet passwords, HP reports.

HP researchers tracked campaigns between April and June 2026 in which a fake AI trading agent site, tradingclaw[.]pro, distributed a Microsoft-signed OLEView executable that DLL side-loads a malicious iviewers.dll and launches Needle Stealer via process hollowing. Needle replaces one of seven browser wallet extensions, including MetaMask, Coinbase Wallet, and Phantom, to capture wallet passwords. Related campaigns used QR-code invoice phishing leading to fake OneDrive pages, Phantom Stealer sold as a penetration testing tool with VBScript-to-PowerShell steganographic loaders, and image-hidden payloads delivering XWorm, PureLogs Stealer, and Formbook; a perceptual-hash VirusTotal search found about 400 distinct rigged images.

Chinese-Speaking Hackers Use Noodle RAT Backdoor to Spy on Windows and Linux Systems

Chinese-speaking actors use cross-platform Noodle RAT backdoor to maintain covert access to Windows and Linux systems across Asia-Pacific.

Noodle RAT (also ANGYREBEL/Nood RAT) has been active since at least mid-2016 and was long misidentified as Gh0st RAT or Rekoobe variants until Trend Micro and Cyberint classified it as a distinct multi-platform family. The Windows build (Win.NOODLERAT) is an in-memory modular shellcode backdoor delivered via MULTIDROP and MICROLOAD loaders, while the Linux build supports reverse shells, SOCKS tunneling, and cron persistence after web shell or public-facing service exploitation. It has appeared in intrusions in Thailand, India, Japan, Malaysia, and Taiwan and is linked to Iron Tiger, Calypso APT, Rocke, and Cloud Snooper campaigns spanning espionage and cybercrime. Recently discovered Linux builders 1.0.1 and 1.0.2 indicate the toolkit remains actively maintained.

Chinese hackers use SparroWocky malware in govt espionage attacks

ESET reports China-linked FamousSparrow deployed a new modular backdoor, SparroWocky, in year-long espionage attacks on Latin American government organizations.

ESET researchers observed FamousSparrow using SparroWocky, a modular C++ backdoor replacing the earlier SparrowDoor tool, against government targets in Argentina, Ecuador, Guatemala, Honduras, Panama, Peru, Puerto Rico, and Venezuela. Deployed via DLL side-loading with an RC4-encrypted payload mapped in memory, it captures screenshots, acts as a TCP proxy, and hooks CreateThread so malicious threads appear as AnimateWindow. Persistence uses a ProcAuditManager Windows service or SnapCart registry key; ESET tracked at least 18 C2 addresses and published IoCs.

Malware bypasses browser checks to force install Chrome, Edge extensions

Elastic Security Labs detailed KREMLIN, a Brazilian banking malware that silently installs malicious Chrome and Edge extensions, with 1,515 confirmed infections.

Elastic Security Labs analyzed KREMLIN, a toolkit used by a Brazilian operation in at least seven campaigns since May 2025 that impersonates 12 banks to trick users into opening a JavaScript file disguised as a bank receipt or invoice. After anti-sandbox checks, it downloads Node.js, persists via a scheduled task, and fetches payload locations from an Ethereum smart contract, hiding payloads in JPEG images on Internet Archive. The toolkit bypasses Chromium integrity mechanisms to install unapproved Chrome/Edge extensions masquerading as AVSync that steal cookies, keylog form input, capture screenshots, and intercept HTTP traffic, while recent campaigns deployed the REMCOS RAT and earlier ones Pulsar RAT. Elastic confirmed 1,515 infected systems, almost all in Brazil, and disrupted the campaign by registering an anti-sandbox canary domain; the linked wallet handled roughly 20,800 USDT incoming and 19,000 USDT outgoing.

Hackers Can Rent VectraRAT for $250 a Month to Take Control of Windows PCs

SOCRadar uncovered VectraRAT, a previously undocumented $250-per-month Windows RAT rental service delivered via Amadey and ClickFix lures.

SOCRadar's Threat Research Unit identified VectraRAT, a rental-only remote access trojan sold by a developer known as Vectra (formerly Nyxel), after an exposed online directory revealed samples, licenses, and operator logs across ten-plus servers. The toolkit includes a Linux control server, Windows implant, payload builder, and VectraHub panel, enabling hidden desktop access, keylogging, command execution, credential theft, file transfer, proxying, and silent privilege escalation. Of victims with OS data, 48 percent ran corporate Windows editions, and researchers recorded 38 genuine victim sessions in under a week, including file theft from business systems. Distribution occurs through the Amadey loader and ClickFix pages impersonating TurboTax, with custom TCP-based C2 over non-standard ports.
