Threat Actors Adopt Havoc Framework for Post-Exploitation in Targeted Attacks

Threat Actors Adopt Havoc Framework for Post-Exploitation in Targeted Attacks

Feb 22, 2023 Exploitation Framework / Cyber Threat
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 generated via th
Hackers Exploit Vulnerabilities in Sunlogin to Deploy Sliver C2 Framework

Hackers Exploit Vulnerabilities in Sunlogin to Deploy Sliver C2 Framework

Feb 07, 2023 Cyber Threat / Malware
Threat actors are leveraging known flaws in Sunlogin software to deploy the Sliver command-and-control (C2) framework for carrying out post-exploitation activities. The findings come from AhnLab Security Emergency response Center (ASEC), which discovered that security vulnerabilities in Sunlogin, a remote desktop program developed in China, are being abused to deploy a wide range of payloads. "Not only did threat actors use the Sliver backdoor, but they also used the  BYOVD  (Bring Your Own Vulnerable Driver) malware to incapacitate security products and install reverse shells," the researchers  said . Attack chains commence with the exploitation of two remote code execution bugs in Sunlogin versions prior to v11.0.0.33 (CNVD-2022-03672 and CNVD-2022-10270), followed by delivering Sliver or other malware such as  Gh0st RAT  and XMRig crypto coin miner. In one instance, the threat actor is said to have weaponized the Sunlogin flaws to install a PowerShell script that, in
How to Achieve the Best Risk-Based Alerting (Bye-Bye SIEM)

How to Achieve the Best Risk-Based Alerting (Bye-Bye SIEM)

Feb 19, 2024Network Detection and Response
Did you know that Network Detection and Response (NDR) has become the most effective technology to detect cyber threats? In contrast to SIEM, NDR offers adaptive cybersecurity with reduced false alerts and efficient threat response. Are you aware of  Network Detection and Response (NDR)  and how it's become the most effective technology to detect cyber threats?  NDR massively upgrades your security through risk-based alerting, prioritizing alerts based on the potential risk to your organization's systems and data. How? Well, NDR's real-time analysis, machine learning, and threat intelligence provide immediate detection, reducing alert fatigue and enabling better decision-making. In contrast to SIEM, NDR offers adaptive cybersecurity with reduced false positives and efficient threat response. Why Use Risk-Based Alerting? Risk-based alerting is an approach where security alerts and responses are prioritized based on the level of risk they pose to an organization's system
