Since late 2022, Earth Baku has broadened its scope from the Indo-Pacific region to Europe, the Middle East, and Africa. Their latest operations demonstrate sophisticated techniques, such as exploiting public-facing applications like IIS servers for initial access and deploying the Godzilla webshell for command and control.
In this blog, we detail our investigation of the Kasseika ransomware and the indicators we found suggesting that the actors behind it have acquired access to the source code of the notorious BlackMatter ransomware.
As the use of ChatGPT and other artificial intelligence (AI) technologies becomes more widespread, it is important to consider the possible risks associated with their use. One of the main concerns surrounding these technologies is the potential for malicious use, such as in the development of malware or other harmful software. Our recent reports discussed how cybercriminals are misusing the large language model’s (LLM) advanced capabilities:
We discussed how ChatGPT can be abused to scale manual and time-consuming processes in cybercriminals’ attack chains in virtual kidnapping schemes.
We also reported on how this tool can be used to automate certain processes in harpoon whaling attacks to discover “signals” or target categories.
In this blog entry, we provide technical details and analysis on the 3CX attacks as they happen. We also discuss available solutions which security teams can maximize for early detection and mitigate the impact of 3CX attacks.
We discovered a new malware, which we named “OpcJacker” (due to its opcode configuration design and its cryptocurrency hijacking ability), that has been distributed in the wild since the second half of 2022.
We analyzed a QAKBOT-related case leading to a Brute Ratel C4 and Cobalt Strike payload that can be attributed to the threat actors behind the Black Basta ransomware.
We compare the targeting and business models of the Conti and LockBit ransomware groups using data analysis approaches. This will be presented in full at the 34th Annual FIRST Conference on June 27, 2022.
We discovered a now-patched vulnerability in macOS SUHelper, designated as CVE-2022-22639. If exploited, the vulnerability could allow malicious actors to gain root privilege escalation.
