THE content discusses the reconstruction of an Akira ransomware kill chain from perimeter and endpoint logs within a mid-sized organization, emphasizing the importance of integrating log sources from firewalls and Windows events. It outlines the phases of the intrusion, including initial access via brute-force attacks on a local SSLVPN account, discovery of domain credentials, lateral movement to gain domain admin privileges, and a rapid sequence of evasion and impact actions leading to data encryption.
The analysis shows that much of the attack could be detected by joining these logs, highlighting several detection and prevention strategies including enforcing MFA, monitoring authentication failures, escalating event log sizes, and synchronizing time across devices. The narrative concludes by stressing that the failure isn't in the absence of signal but in the lack of retention and integration of logs to respond effectively to incidents.
