According to the source, security researchers have documented that the Astaroth (Guildma) banking trojan abuses GitHub to host and retrieve malicious payloads, enabling large-scale credential theft while blending with legitimate traffic, source: Avast Threat Labs and Cisco Talos. Astaroth operates largely fileless and leverages Windows living-off-the-land tools such as WMIC and BITSAdmin to evade detection while harvesting credentials from browsers and email clients, source: Microsoft Security Intelligence. This behavior elevates account-takeover risk for crypto traders who log in to exchanges or manage hot wallets on infected PCs, as stolen credentials remain a leading breach vector, source: Verizon 2024 Data Breach Investigations Report. To mitigate risk, use phishing-resistant multi-factor authentication with hardware security keys for exchange accounts and enable withdrawal address allowlisting, source: NIST SP 800-63B and Binance Support. Storing trading funds in hardware wallets and installing software only from verified sources further limits exposure to malware-based theft, source: Ledger Security and Microsoft Security Intelligence.
