Akira Ransomware: Full Kill Chain IR

At 2025-08-01T09:14:56.565Z, a high-priority alert indicated a potential unauthorized access attempt targeting our internal file server. Analyze the network traffic logs to determine which external entity initiated the connection that bypassed the standard perimeter filters.

An unauthorized process execution was detected on corp-wks-42 at 2025-08-01T11:44:54.495Z, originating from a temporary directory. You must investigate the telemetry to find the unique cryptographic identifier of the file that was used to establish an initial foothold.

Following a suspicious process execution on corp-wks-101, network logs indicate a potential data exfiltration attempt or beaconing behavior. Review the network telemetry to determine which external infrastructure the host was communicating with at the time of the alert.

During the timeline reconstruction of the incident on dc-prod-01, an unusual execution was detected. To verify the integrity of our telemetry, we need to confirm which specialized logging agent reported this specific activity at 2025-08-01T09:20:06.485Z.

Around 2025-08-14T03:00:00Z, several automated alerts triggered indicating unauthorized data encryption on file-srv-01. You must investigate the XDR panel to determine which specific sub-technique or technique was mapped to this disruptive activity.

After gaining initial access, the adversary attempted to stabilize their connection to the domain controller. Using the firewall logs, determine which destination port was targeted during the suspicious inbound traffic spike from the unknown external source.

After the initial compromise on corp-wks-42, the attacker attempted to pivot deeper into the internal network. Analyze the endpoint logs from the morning of August 4th to determine which production asset was targeted during the lateral movement phase.

An alert triggered for a suspicious outbound connection from a high-value domain controller. You must analyze the network telemetry to determine which local process initiated this traffic to ensure it is not a masquerading attempt or a malicious beacon.

An alert was triggered on corp-wks-42 involving the itadm account. You need to determine the specific phase of the attack lifecycle that the adversary was attempting to execute when they interacted with the local security authority process.

A high-severity alert triggered on corp-wks-101 involving the user asmith. Investigation into the behavioral logs suggests a shell was used to modify registry keys for persistence; you must determine the exact initiating process name that spawned this activity.
