Welcome to this week’s edition of the Threat Source newsletter. I’m fascinated by how things live and die on the internet. Things that are ubiquitous to our daily lives are simply gone the next. LiveJournal and Myspace we hardly knew you. Elon Musk’s purchase
In late October two new buffer overflow vulnerabilities, CVE-2022-3602 and CVE-2022-3786, were announced in OpenSSL versions 3.0.0 to 3.0.6. These vulnerabilities can be exploited by sending an X.509 certificate with a specially crafted email address, potentially causing a buffer overflow resulting in a crash or

It can be difficult to determine what constitutes a pre-ransomware attack if ransomware never executes and encryption does not take place. However, Talos IR assesses that the combination of Cobalt Strike and credential-harvesting tools like Mimikatz, paired with enumeration and discovery techniques, indicates a high likelihood that ransomware is the final objective. This quarter featured a variety of publicly available tools and scripts hosted on GitHub repositories or other third-party websites to support operations across multiple stages of the attack lifecycle. This activity coincides with a general increase in the use of other dual-use tools, such as the legitimate red-teaming ...
