Crypto users at risk as Microsoft uncovers StilachiRAT malware stealing wallet data

Microsoft has issued an alert about a new malware, StilachiRAT, that stealthily targets cryptocurrency wallets and steals information stored in browsers like Google Chrome.

According to a Mar. 17 announcement StilachiRAT is a remote access trojan (RAT) designed to evade detection and exfiltrate sensitive data.

StilachiRAT poses a serious threat to crypto users. Notably, the malware actively scans for crypto wallet extensions in Google Chrome, targeting at least 20 different wallets, including MetaMask, Trust Wallet, Phantom, Coinbase, BNB Chain, and Bitget Wallet, among others.

Once detected, the malware can extract stored credentials and configuration data, which, in turn, allows attackers to drain victims’ funds.

Additionally, StilachiRAT monitors clipboard activity, searching for cryptocurrency keys and passwords that users may have copied, making it a direct threat to digital asset security.

The malware allows attackers to remotely execute remote commands, clear logs, and manipulate registry settings to maintain access. It employs anti-forensic measures, such as detecting analysis tools and delaying execution, to bypass security monitoring.

One of its key capabilities is system reconnaissance. StilachiRAT collects detailed information about the infected device, including OS details, hardware identifiers, and active applications. It also monitors Remote Desktop Protocol sessions, allowing attackers to impersonate users and move laterally across networks.

Microsoft has not yet attributed the malware to a specific threat actor but warns that its stealth and advanced evasion tactics make it a serious risk. 

While it is not yet widespread, Microsoft has urged users to exercise caution.

“Malware like StilachiRAT can be installed through multiple vectors; therefore, it is critical to implement security hardening measures to prevent the initial compromise,” the tech giant warned.

Recommended precautions include downloading software only from official sources, enabling Microsoft Defender real-time protection, turning on cloud-delivered security, and using SmartScreen to block malicious websites.

The crypto sector has long been targeted using increasingly sophisticated malware and cyberattacks. From wallet-draining trojans to phishing scams, attackers continue to evolve their tactics to exploit vulnerabilities.

As previously reported by crypto.news, the $1.4 billion Bybit hack, the biggest crypto theft to date, allegedly started with malware disguised as a fake stock investment project.

Late last year, on-chain investigator Taylor Monahan flagged a sophisticated social engineering scheme that pushed malware onto victims’ devices during a fake job interview process.
