VM console

headless guest

The Linux sandbox runs a server image with no desktop, so there is no screen to record - this is the boot console, kept because a kernel panic or an out-of-memory kill would show up here and in no other layer. What the sample did is under Behavior, File & registry and Network, captured from the syscall trace rather than from pixels.

Analyst narrative

The analysis indicates that the sample executed successfully within the sandbox environment. The following kill-chain elements were observed: 1. **Initial Access**: There is no specific evidence of initial access mechanisms such as phishing or exploitation, as the analysis does not provide details on how the sample was delivered or executed. 2. **Execution**: The sample was executed, as evidenced by the observed process creation of `e` with the command line `/var/tmp/e`. This indicates that the sample was able to run in the environment. 3. **Persistence**: No persistence mechanisms were detected. The analysis did not reveal any attempts to establish a foothold on the system beyond the initial execution. 4. **Defense Evasion**: There were no specific indicators of defense evasion techniques employed by the sample. The behavior summary does not mention any actions taken to avoid detection. 5. **Command and Control (C2)**: The sample attempted to connect to a URL associated with potential malicious activity: `hxxp://rootkiter.com/EarthWrom/`. This suggests that the sample may have been designed to communicate with a command and control server. 6. **Impact**: The impact of the sample is unclear due to a lack of further observable malicious actions or effects beyond the initial execution and attempted C2 communication. In conclusion, while the sample executed and attempted to reach out to a C2 server, there is insufficient evidence to determine its overall intent or impact. The lack of persistence and defense evasion signals suggests that the sample may not have been fully developed or operational in its malicious capabilities. The verdict is based on the observed behavior and the attempt to connect to a known malicious URL.

Extracted files

What came out of the sample: unpacked payloads, carved objects and captured memory. Each one is stored by content hash, so the same object extracted twice is the same row.

No extracted files

Nothing was unpacked or carved out of this sample. Packed samples, documents with embedded objects and installers are the ones that usually produce artifacts here.
