BBSRAT

BBSRAT is a type of malware, harmful software designed to infiltrate and damage computers or devices. It is typically found within a portable executable file, although there have been instances where it was discovered in a raw DLL. The malware can enter a system through suspicious downloads, emails, or websites, often without the user's knowledge. Once inside, BBSRAT has the potential to steal personal information, disrupt operations, or hold data hostage for ransom. Recent attack campaigns using BBSRAT suggest that the adversary may deploy purpose-built variants and/or infrastructure for each intended target. The most recent example of BBSRAT was found in AutoFocus, where the Trojan was deployed via a downloader that used the Invoke-ReflectivePEInjection.ps1 script from the PowerSploit framework. This downloaded executable contained a copy of the BBSRAT malware family. In some cases, the malware was delivered through spear-phishing emails. Tools such as AutoFocus and WildFire properly classify BBSRAT malware samples as malicious, allowing users to explore these attacks in more detail. Once loaded, BBSRAT begins execution by loading certain libraries at runtime. It accepts many possible commands that the C2 server can provide, indicating its flexibility and adaptability in different attack scenarios. Its behaviors include calling the WSAStartup function, among others. With the continuous evolution of this malware, it's crucial for individuals and organizations to stay updated on its latest developments and implement robust cybersecurity measures to mitigate potential threats.
