A recent phishing campaign impersonates Amazon security alerts to deliver a custom remote access trojan (RAT) dubbed HarborWatch Agent. The attack leverages the ClickFix technique, using a fake CAPTCHA page to socially engineer victims into manually executing a malicious PowerShell command via the Windows Run dialog. Once executed, the script downloads the RAT, which collects system information and communicates with a C2 infrastructure managed via a panel called Harbor Sentinel.
A newly discovered malware campaign dubbed Argamal targets users downloading adult games, utilizing DLL sideloading and COM hijacking to deploy a sophisticated Remote Access Trojan (RAT). The malware establishes persistence by hijacking the Windows Color System Calibration Loader and grants attackers full system control, including surveillance, file exfiltration, and arbitrary command execution.
JS.MonoGlyphRAT is a newly identified, highly obfuscated JavaScript backdoor targeting US enterprises via phishing. It establishes persistence, communicates over HTTP using custom headers, and acts as a loader capable of executing AES-encrypted payloads, PowerShell commands, and in-memory .NET assemblies while bypassing AMSI.
A cybercrime campaign is targeting users of pirated media sites with a fake video player update that deploys a modified SilentCryptoMiner and a Remote Access Trojan (RAT). The malware utilizes DLL side-loading, DNS tunneling for initial check-ins, and a DGA for C2 communications, while employing a Watchdog component to ensure persistence via a rogue Google Update service.
Unit 42 identified 18 high-risk browser extensions masquerading as GenAI productivity tools that function as remote access Trojans, infostealers, and spyware. These extensions exploit browser permissions to intercept API keys, exfiltrate DOM content, establish persistent WebSocket C2 channels, and dynamically route traffic via malicious proxy configurations.
Threat actors are increasingly weaponizing legitimate software and known vulnerabilities to bypass endpoint detection and response (EDR) systems. Between December 2021 and December 2024, the abuse of legitimate Remote Access Tools (RATs) like NetSupport Manager and ConnectWise has surged, often delivered via phishing emails exploiting older Microsoft Office vulnerabilities to establish persistent, stealthy access.
A software supply chain compromise impacted the Axios npm package, injecting a malicious dependency ([email protected]) into versions 1.14.1 and 0.30.4. This dependency downloads multi-stage payloads, including a Remote Access Trojan (RAT), which communicates with a known malicious C2 domain.
North Korea's Contagious Interview campaign has launched a coordinated supply chain attack across five major open-source ecosystems. The threat actors published malicious packages masquerading as legitimate developer tools that act as staged loaders to deliver remote access trojans (RATs) and infostealers to developer workstations.
A critical supply chain attack compromised the official Axios npm package, deploying malicious versions v1.14.1 and v0.30.4. The packages contained a fake runtime dependency that automatically executed post-install, downloading platform-specific Remote Access Trojans (RATs) to Windows, MacOS, and Linux systems to facilitate credential exfiltration and remote access.
A critical supply chain attack compromised the widely used Axios npm package, publishing malicious versions that introduced a trojanized dependency. This dependency executes a multi-stage remote access trojan (RAT) across Windows, macOS, and Linux systems, utilizing obfuscation and anti-forensics to evade detection and establish persistence.
On March 31, 2026, the popular Axios npm package was compromised in a supply chain attack attributed to North Korean threat actor Sapphire Sleet. Malicious versions 1.14.1 and 0.30.4 included a fake dependency that silently executed a post-install script to download and install OS-specific Remote Access Trojans (RATs) on Windows, macOS, and Linux systems.
A critical supply chain attack compromised the popular Axios npm package, utilizing a malicious transitive dependency to execute cross-platform payloads during installation. The attack targets Linux, Windows, and macOS systems, deploying OS-specific Remote Access Trojans (RATs) capable of host profiling, command execution, and follow-on payload delivery. Detection engineering efforts should focus on anomalous process ancestry, such as Node.js spawning native OS shells to retrieve and background remote payloads.
A supply chain attack compromised the widely used Axios npm package (versions 1.14.1 and 0.30.4) following a maintainer account takeover. The malicious packages deploy a cross-platform remote access trojan (RAT) during installation, which fetches second-stage payloads and actively evades forensic detection by cleaning up artifacts and altering package metadata.
The highly popular Axios npm package was compromised when an attacker hijacked a lead maintainer's account to publish malicious versions. These versions included a phantom dependency that deployed a cross-platform Remote Access Trojan (RAT) via a postinstall hook, utilizing advanced obfuscation and anti-forensic techniques to hide its presence. The attack highlights critical risks in the software supply chain, specifically regarding dependency resolution and CI/CD pipeline protections.
Threat actor TeamPCP orchestrated a cascading supply chain attack by exploiting a misconfigured GitHub Actions workflow in Aqua Security's Trivy, harvesting credentials to compromise subsequent repositories including Checkmarx, LiteLLM, and Telnyx. The malicious packages deploy sophisticated, OS-specific remote access trojans (RATs) that utilize steganography, process hollowing, and ETW patching to evade detection while exfiltrating sensitive data.
Threat actors are leveraging WebDAV and Windows File Explorer to deliver Remote Access Trojans (RATs) while bypassing traditional web browser security controls. By utilizing .url and .lnk shortcut files pointing to WebDAV servers hosted on temporary Cloudflare Tunnels, attackers can trick users into executing malicious scripts that appear as local files.
