StilachiRAT: New Chrome Extension Malware Steals Crypto Wallet Data

The security team at Microsoft has recently uncovered a remote access trojan (RAT) specifically targeting cryptocurrency wallet extensions within the Google Chrome browser. Identified as StilachiRAT in November last year, this malware poses significant risks by stealthily harvesting sensitive information, including wallet credentials, passwords, and various personal details stored in the browser.

StilachiRAT primarily focuses on users who have installed specific wallet extensions, such as popular wallets like MetaMask, Trust Wallet, and Coinbase Wallet. Once installed on a device, the malware discreetly scans for these extensions, gaining unauthorized access to cryptocurrency-related data. According to the investigation, the malware is even capable of extracting stored credentials embedded in Chrome’s local files.

Advanced Evasion Techniques

An unsettling aspect of StilachiRAT is its sophisticated ability to evade detection. It employs several tactics intended to hide its presence, including the deletion of event logs, and checks for signs of controlled environments such as sandboxes. These deliberate methods make the malware particularly challenging to detect and neutralize.

Implications for Cryptocurrency Users

Even though the distribution of StilachiRAT has been relatively contained so far, its advanced stealth features leave cryptocurrency users vulnerable to long-term risks. Microsoft’s discovery of this malware serves as a reminder of the persistent threat posed by cybercriminals in the rapidly evolving digital landscape.

Recommendations for Enhanced Security

In light of these findings, experts advise all Internet users—especially those involved in cryptocurrency trading—to reinforce their security measures. Users are encouraged to deploy reputable antivirus software and consider cloud-based defense solutions to mitigate risks from targeted attacks.
