Rewterz Threat Alert – BlackLotus Malware – Active

Severity

High

Analysis Summary

BlackLotus is a type of malware that belongs to the family of botnets and is used to launch Distributed Denial of Service (DDoS) attacks. This malware infects computers and uses them as part of a botnet to launch attacks against specific targets. The main purpose of the attack is to overwhelm the target’s network with a flood of traffic, making it inaccessible to legitimate users.

BlackLotus works by infecting a computer and communicating with a command and control (C&C) server to receive instructions. Once the botnet is established, attackers can use it to launch DDoS attacks against specific targets. BlackLotus malware is designed to be difficult to detect and can use various techniques to evade detection, including encryption and obfuscation of its code.

BlackLotus malware can be transmitted through a variety of methods, including email attachments, malicious websites, and software vulnerabilities. Once the malware has infected a computer, it can use various methods to maintain its presence on the system, including modifying registry entries and creating hidden files.

The impact of BlackLotus malware can be severe, especially for businesses and organizations that rely heavily on their online presence. The attacks can cause significant disruptions to services, leading to lost revenue and a damaged reputation. Furthermore, DDoS attacks can be used as a distraction or smokescreen to cover up other types of cyberattacks, such as data theft or network infiltration.

Remediation

• Block all threat indicators at your respective controls.
• Search for Indicators of compromise (IOCs) in your environment utilizing your respective security controls
• Maintain cyber hygiene by updating your anti-virus software and implementing a patch management lifecycle.
• Maintain Offline Backups – In a ransomware attack, the adversary will often delete or encrypt backups if they have access to them. That’s why it’s important to keep offline (preferably off-site), encrypted backups of data and test them regularly.
• Emails from unknown senders should always be treated with caution.
• Users should upgrade their applications and V3 to the most recent version and avoid opening documents from unknown sources.
• Never trust or open ” links and attachments received from unknown sources/senders.
