Brute Ratel C4 | Breaking Cybersecurity News | The Hacker News

An open source command-and-control (C2) framework known as Havoc is being adopted by threat actors as an alternative to other well-known legitimate toolkits like  Cobalt Strike ,  Sliver , and  Brute Ratel . Cybersecurity firm Zscaler said it observed a new campaign in the beginning of January 2023 targeting an unnamed government organization that utilized  Havoc . "While C2 frameworks are prolific, the open-source Havoc framework is an advanced post-exploitation command-and-control framework capable of bypassing the most current and updated version of Windows 11 defender due to the implementation of advanced evasion techniques such as indirect syscalls and sleep obfuscation," researchers Niraj Shivtarkar and Shatak Jain  said . The attack sequence documented by Zscaler begins with a ZIP archive that embeds a decoy document and a screen-saver file that's designed to download and launch the Havoc Demon agent on the infected host. Demon is the implant genera...

The threat actors behind the  Black Basta   ransomware family  have been observed using the Qakbot trojan to deploy the Brute Ratel C4 framework as a second-stage payload in recent attacks. The development marks the first time the  nascent adversary simulation software  is being delivered via a Qakbot infection, cybersecurity firm Trend Micro  said  in a technical analysis released last week. The intrusion, achieved using a phishing email containing a weaponized link pointing to a ZIP archive, further entailed the use of Cobalt Strike for lateral movement. While these legitimate utilities are designed for conducting penetration testing activities, their ability to offer remote access has made them a lucrative tool in the hands of attackers looking to stealthily probe the compromised environment without attracting attention for extended periods of time. This has been compounded by the fact that a  cracked version  of Brute Ratel C4 (BRc4 ...

The problem is simple: all breaches start with initial access, and initial access comes down to two primary attack vectors – credentials and devices. This is not news; every report you can find on the threat landscape depicts the same picture.  The solution is more complex. For this article, we'll focus on the device threat vector. The risk they pose is significant, which is why device management tools like Mobile Device Management (MDM) and Endpoint Detection and Response (EDR) are essential components of an organization's security infrastructure. However, relying solely on these tools to manage device risk actually creates a false sense of security. Instead of the blunt tools of device management, organizations are looking for solutions that deliver device trust . Device trust provides a comprehensive, risk-based approach to device security enforcement, closing the large gaps left behind by traditional device management solutions. Here are 5 of those limitations and how to ov...
