The digital landscape is facing yet another threat as a stealthy malware, christened Bandit Stealer, enters the arena. Security experts are closely monitoring this emerging danger due to its unique capacity to compromise various web browsers and cryptocurrency wallets.
Shedding light on Bandit Stealer
Engineered using the versatile Go programming language, Bandit Stealer showcases the potential for cross-platform adaptability. As of now, it concentrates its malicious activities predominantly on Windows systems. It cleverly leverages a valid command-line tool called runas.exe that permits programs to operate under different users and permissions. The malware utilizes this opportunity to escalate its privileges and effectively skirt security barriers to harvest extensive data.
Microsoft’s access control safeguards present challenges to Bandit Stealer. An attempt to execute the malware as an administrator necessitates the provision of the required credentials. Despite this, Bandit Stealer’s operation enables users to run applications with elevated privileges or carry out system-level tasks securely.
Bandit Stealer: The method behind the menace
Upon infiltrating a system, Bandit Stealer runs checks to determine if it’s in a sandbox or virtual environment. To remain undetected, it terminates a set of blacklisted processes. The malware then manipulates Windows Registry to ensure its persistence and initiates its data collection activities, which include harvesting personal and financial data stored in web browsers and crypto wallets.
Currently, the primary mode of Bandit Stealer’s distribution is through phishing emails containing a dropper file. The file opens a harmless Microsoft Word attachment as a decoy, while in the background, the malware infection process gets underway.
The state of the Info Stealer market
While Bandit Stealer presents a fresh menace, the information stealer malware category is witnessing constant evolution. Cybersecurity experts have identified several new strains of commodity stealer malware, with some disseminated via spam emails and counterfeit versions of popular software. The malware-as-a-service (MaaS) market, in addition to this, has been facilitating easy access to such malware for aspiring cybercriminals.
Data collected by Secureworks Counter Threat Unit (CTU) has revealed a booming infostealer market, with the number of stolen logs on underground forums witnessing a significant increase. “The infostealer market is thriving, and there is an entire underground economy built around it. It’s lucrative and accessible for relatively low-skilled threat actors,” warns Don Smith, Vice President of Secureworks CTU.
Bandit Stealer’s emergence underscores the need for vigilance and robust security measures in the digital space. As malware evolves, so must our defenses against these threats.
