This string suggests it could be related to a video file, given the structure and extension. Here's a breakdown and an informative feature based on the provided string: fc2ppv4436953part08rar
If you see a massive archive inside the extracted folder, first check the compression ratio:
du -sh analysis/extracted/inner.zip
unzip -l analysis/extracted/inner.zip | awk 'print $1' | paste -sd+ - | bc
A ratio > 100:1 is a red flag. Use unzipsfx -l or 7z t with the -bb3 flag to see the total uncompressed size before extracting. | If you want to study
| Action | Command | Reason |
|--------|---------|--------|
| PDF analysis | pdfid.py <file> → look for /JavaScript | PDFs often embed malicious JS. |
| Office macros | olevba <file> | Extract VBA macros, decode obfuscation. |
| JavaScript deobfuscation | js-beautify + manual inspection | Attackers hide URLs in eval/hex strings. |
| PowerShell detection | grep -i "Invoke-Expression" <script> | Classic PowerShell droppers. |
| Network IOCs | grep -Eo "(http|https)://[^\"]+" <file> | Pull out C2 endpoints. |
tree analysis/extracted
ls -lR analysis/extracted
Make a note of the file types you see (file on each, sha256sum for later reference). A ratio > 100:1 is a red flag
If the extraction fails with errors like “CRC error”, the archive is either corrupted or the password is wrong.
