IoT Botnet Linked to Large-scale DDoS Attacks Since the End of 2024
Since the end of 2024, we have been continuously monitoring large-scale DDoS attacks orchestrated by an IoT botnet exploiting vulnerable IoT devices such as wireless routers and IP cameras.
Information Stealer Masquerades as LDAPNightmare (CVE-2024-49113) PoC Exploit
In December 2024, two critical vulnerabilities in Microsoft's Windows Lightweight Directory Access Protocol (LDAP) were addressed via Microsoft’s monthly Patch Tuesday release. Both vulnerabilities were deemed as highly significant due to the widespread use of LDAP in Windows environments: CVE-2024-49112: A remote code execution (RCE) bug that attackers can exploit by sending specially crafted LDAP requests, allowing them to execute arbitrary code on the target system. CVE-2024-49113: A denial-of-service (DoS) vulnerability that can be exploited to crash the LDAP service, leading to service disruptions. In this blog entry, we discuss a fake proof-of-concept (PoC) exploit for CVE-2024-49113 (aka LDAPNightmare) designed to lure security researchers into downloading and executing information-stealing malware.
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.
Social Media Malvertising Campaign Promotes Fake AI Editor Website for Credential Theft
We uncovered a malvertising campaign where the threat actor hijacks social media pages, renames them to mimic popular AI photo editors, then posts malicious links to fake websites.
A Closer Look at ChatGPT's Role in Automated Malware Creation
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.
New OpcJacker Malware Distributed via Fake VPN Malvertising
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.
Black Basta Ransomware Gang Infiltrates networks via QAKBOT, Brute Ratel, and Cobalt Strike
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.
Conti vs. LockBit: A Comparative Analysis of Ransomware Groups
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.
