The Wacatac Trojan is a type of malware first documented in January 2020, known for disguising itself as benign software to trick users into installation. It operates under various aliases, including Trojan:Script/Wacatac and Trojan:Win32/Wacatac, and can connect to Command-and-Control (C2) servers for remote manipulation. Its capabilities include stealing credentials, evading antivirus detection, creating or joining botnets, causing system damage, enabling spyware functions, acting as Remote Access Tools (RATs), and downloading additional malware. Symptoms of infection include sluggish performance, program failures, unexplained storage reductions, and unfamiliar processes. Wacatac spreads through unofficial software, malicious web pages, and phishing emails. Removal is best achieved using reputable antivirus software, while prevention involves avoiding questionable downloads, practicing good digital hygiene, keeping software updated, backing up data, and using quality antivirus solutions. False positives can occur, where legitimate programs are mistakenly flagged as Wacatac.

Fileless malware operates within a computer's active memory, avoiding detection by traditional antivirus solutions that rely on file scanning. It uses legitimate tools like PowerShell to execute harmful commands without creating files, making it difficult to identify. Cybercriminals can use fileless malware for various malicious activities, including data theft and cryptocurrency mining. Malwarebytes combats fileless attacks through two defense layers: Script Monitoring, which intercepts potentially dangerous scripts at execution, and Command-Line Protection, which scrutinizes command-line tools for suspicious activities. Examples of fileless attacks include malicious email attachments activating PowerShell to download ransomware, hidden JavaScript on websites mining cryptocurrency, and attackers using Windows Management Instrumentation (WMI) to create backdoors. Malwarebytes' Fileless Protection operates automatically in the background, ensuring legitimate applications function normally while monitoring for threats. It is part of a comprehensive security framework that includes machine-learning detection and web protection, designed to stop attacks that do not write files. This protection is included with Malwarebytes Premium, aimed at safeguarding personal and small business systems.
