Quant Loader

Quant Loader is a significant threat actor in the realm of cybersecurity, known for executing actions with malicious intent. It has been linked to various malware campaigns, distributing harmful software such as GandCrab ransomware, DreamSmasher, Dridex, and itself - Quant Loader. The threat actor operates by downloading via JavaScript, which in turn fetches additional harmful payloads, enhancing its destructive capabilities. A notable example of its operation is the delivery of the FlawedAmmyy Remote Access Trojan (RAT), often through the intermediate Quant Loader malware. In this scenario, the JavaScript downloads Quant Loader, which then fetches the FlawedAmmyy RAT as the final payload. This method of distribution was particularly prevalent in campaigns observed during March and April. The threat posed by Quant Loader is substantial, as evidenced by various ET TROJAN alerts such as 2023203 and 2024452, which indicate Quant Loader download requests. Its ability to serve as an intermediary for other malware, coupled with its sophisticated delivery methods, underscores the importance of robust cybersecurity measures to guard against such threats.
