Inferno Drainer Steals $9M in Six Months, Targets Discord Users

Inferno Drainer, a notorious malware known for stealing cryptocurrency, has resurfaced and managed to pilfer over $9 million from crypto wallets in just six months. Despite claims from its developers that they had ceased operations in November 2023, the malware has continued to drain funds from over 30,000 crypto wallets. This resurgence highlights the evolving tactics of cybercriminals in the digital currency space.

According to cybersecurity experts, the malware's developers have made significant improvements to its capabilities. The updated version of Inferno Drainer now employs single-use smart contracts and on-chain encrypted configurations, making it much harder to detect and prevent attacks. Additionally, the command-and-control server communication has been obfuscated through proxy-based systems, further complicating efforts to track and mitigate the threat.

The resurgence of Inferno Drainer is accompanied by a sophisticated phishing campaign targeting users on the Discord platform. This campaign uses social engineering techniques to redirect users from legitimate Web3 project websites to counterfeit sites that mimic the verification process for the popular Discord bot Collab.Land. The fake site hosts a cryptocurrency drainer, which tricks victims into signing malicious transactions, allowing attackers to gain access to their funds.

By combining targeted deception and effective social engineering tactics, the malware campaign has managed to generate a stable financial flow, as identified through blockchain transaction analysis. This underscores the need for heightened vigilance among crypto users, who are advised to exercise extra caution when interacting with unfamiliar platforms. The fake Collab.Land bot identified by researchers contained only subtle visual differences from the legitimate bot, making it difficult for even experienced users to detect the deception.

The revival of Inferno Drainer is part of a broader trend of increasingly sophisticated malware campaigns targeting cryptocurrency users. Hackers are adopting advanced techniques to deliver crypto-stealing malware, exploiting vulnerabilities in hacked mailing lists, open-source Python libraries, and even preloading trojans on counterfeit Android phones. This evolving threat landscape underscores the importance of robust cybersecurity measures and user education in protecting digital assets.
