12 december 2023
Tis the season for understanding TA422’s latest activity AND for singing podcast guests!
Today’s returning guest is Greg Lesnewich, Senior Threat Researcher at Proofpoint. He sheds light on the tactics, techniques, and procedures (TTPs) employed by TA422. The conversation touches on the significance of the high volumes observed starting in late summer, the exploitation of vulnerabilities for NTLM credential harvesting, and the brief usage of the WinRAR vulnerability.
They touch upon the potential reasons behind the group's choices, considering factors such as resourcing, tactical decisions, and a shift towards speed and efficiency. There is also consideration about connecting TA422's activities to broader trends in threat actor behavior, such as a shift towards living off the land techniques and a focus on social engineering for initial access.
The conversation continues on the following topics:
