Threats Tagged 'proxyware'

A fraudulent website impersonating Corepack, the Node.js package manager tool, is distributing malware to developers. The attackers exploit timing around Corepack's removal from Node.js bundling, targeting developers searching for installation instructions. The site offers Windows executables that deliver OpenShield infostealer and proxyware, enrolling victim machines in bandwidth-sharing networks without consent. The payload steals browser credentials, SSH keys, establishes persistence, and routes third-party traffic through compromised systems. An alternative download path delivers adware and trojan components disguised as OperaGX installer. The site features AI-generated content with obvious errors, including confusing Yarn package manager with textile crafts. The domain has been reported to registrars for takedown after community members identified the threat.

An Android proxyware SDK named Popa enrolls consumer devices including phones, tablets, and streaming boxes into a commercial residential proxy network. Operating since at least 2020, Popa and its variants (Loopop, Neupop, and Moneytiser) are distributed inside consumer streaming, IPTV, and utility applications. The SDK begins relaying third-party traffic at host-app launch without displaying informed-consent prompts in analyzed samples. Multiple variants communicate directly with NetNut SDK endpoints, sharing operational infrastructure and telemetry. Controlled testing showed traffic from Popa-enrolled devices egressing through NetNut's commercial gateway. The SDK uses encrypted Google Drive files to resolve relay servers in later versions. Analysis of over 20 publishers revealed significant links to piracy-related applications, with none observed requesting user consent despite later builds including this capability.

A sophisticated attack chain was uncovered involving a malicious disk-cleaning utility that installed proxyware on a compromised system. The infection used PowerShell scripts, download cradles, and in-memory execution to evade detection and establish a connection to a command-and-control (C2) server. The attack was intercepted before the proxyware installation completed. This incident underscores the dangers of unauthorized software installations and the critical need to restrict PowerShell usage in corporate environments. The threat leverages multiple advanced techniques including obfuscation, living-off-the-land binaries, and scheduled task abuse. Although no known exploits are currently in the wild, the attack demonstrates a medium severity risk due to its potential for stealthy persistence and resource abuse. European organizations should be vigilant, especially those with lax software installation policies and insufficient PowerShell controls.

This report details a campaign involving NodeJS backdoors used to distribute proxyware and monetization schemes. The attackers employ Inno setup installers to drop PowerShell scripts that download and execute NodeJS packages with malicious JavaScript. The backdoors collect system information, communicate with command and control servers, and can execute various commands including PowerShell scripts and additional Node.js code. The campaign is associated with multiple proxyware applications like Infatica, Honeygain, earnFM, and PacketLab. The attackers also use browser extensions to track user navigation and potentially redirect to malicious URLs. The infrastructure involves numerous domains and cloud services for hosting malware and command and control.

A malicious campaign is targeting users through fake YouTube video download sites, distributing Proxyware malware. The attack involves a downloader disguised as WinMemoryCleaner, which installs NodeJS and runs malicious JavaScript. This script then installs various Proxyware programs, including DigitalPulse, HoneyGain, and recently, Infatica. The malware uses Task Scheduler for persistence and sends system information to a C&C server. The Proxyware exploits the infected system's network bandwidth for the attacker's profit. Users in South Korea have been particularly targeted. To prevent infection, users should avoid installing executables from suspicious websites and use antivirus software.
