Below is a copy‑and‑paste ready script (with comments) that implements the workflow on a typical Ubuntu/Debian system. Feel free to adapt it for macOS or Windows (using PowerShell equivalents).
#!/usr/bin/env bash
# --------------------------------------------------------------
# Safe inspection of nwoleaks.com/zip/609.zip
# --------------------------------------------------------------
# 1️⃣ Settings -------------------------------------------------
ZIP_URL="https://nwoleaks.com/zip/609.zip"
ZIP_FILE="609.zip"
TMPDIR=$(mktemp -d -t zipinspect-XXXX) # isolated read‑only dir
EXTRACT_DIR="$TMPDIR/extracted"
mkdir -p "$EXTRACT_DIR"
# 2️⃣ Download -------------------------------------------------
echo "[*] Downloading $ZIP_URL ..."
curl -L -o "$ZIP_FILE" "$ZIP_URL"
# 3️⃣ Verify hash (if you have a known hash) -------------------
# Uncomment and replace the value if you have a reference hash
# EXPECTED="ab12cd34ef56..."
# echo "$EXPECTED $ZIP_FILE" | sha256sum -c -
# 4️⃣ Quick AV scan (VirusTotal) -------------------------------
echo "[*] Uploading to VirusTotal (optional)..."
# You need a VT API key; skip if you prefer manual upload.
# VT_KEY="YOUR_API_KEY"
# curl -s --request POST \
# --url https://www.virustotal.com/api/v3/files \
# --header "x-apikey: $VT_KEY" \
# --form "file=@$ZIP_FILE"
# 5️⃣ List contents (no extraction) ----------------------------
echo "[*] Listing archive contents:"
zipinfo -l "$ZIP_FILE"
# 6️⃣ Extract to non‑exec RAM disk -------------------------------
echo "[*] Extracting to sandboxed location ..."
unzip -qq "$ZIP_FILE" -d "$EXTRACT_DIR"
# 7️⃣ Second‑stage scan (ClamAV + YARA) -----------------------
echo "[*] Running ClamAV scan on extracted files ..."
clamscan -r "$EXTRACT_DIR"
# Example YARA rule: look for embedded PE executables
cat > /tmp/has_pe.yara <<'EOF'
rule EmbeddedPE
meta:
description = "Detects PE header inside any file"
strings:
$pe = 4D 5A 90 00 // 'MZ' header
condition:
$pe at 0
EOF
echo "[*] Running YARA ..."
yara -r /tmp/has_pe.yara "$EXTRACT_DIR"
# 8️⃣ Manual peek – list top‑level structure --------------------
echo "[*] Directory tree:"
tree "$EXTRACT_DIR"
# 9️⃣ Clean up (optional – keep if you need the logs)
# rm -rf "$TMPDIR"
echo "[*] Inspection complete. Review the log above and any AV/YARA reports."
What the script does for you
You can expand step 8 with more specialized tools (e.g., pdfid, peepdf, exiftool) if the archive contains PDFs, Office documents, or images. nwoleakscomzip609zip link
If you have a legitimate ZIP file that needs extraction, follow these steps:
Scan for Malware:
Extract the File:
Check for Passwords:
Inspect the Contents:
# Example (Linux/macOS)
mkdir /tmp/nwoleaks_609
cd /tmp/nwoleaks_609
sha256sum /path/to/nwoleakscomzip609zip # verify hash first
7z x /path/to/nwoleakscomzip609zip
| Observation | Why it’s suspicious | Suggested next step |
|-------------|---------------------|---------------------|
| Executable inside a “documents” folder (*.exe, *.dll, *.scr) | Attackers often hide malicious binaries among innocuous‑looking files. | Quarantine the file, upload to VirusTotal, run it in a detached sandbox (e.g., Cuckoo). |
| Double extensions (report.pdf.exe) | Windows may treat it as an executable despite the visible PDF. | Rename to remove the fake extension; scan the file. |
| Embedded scripts in PDFs (/JS, /AA) | PDF JavaScript can exploit reader vulnerabilities. | Open the PDF with a script‑blocking viewer (e.g., pdf-parser.py --search /JS). |
| Large base‑64 blobs inside .txt or .json files | Often used to ship malware payloads that are later decoded. | Extract the blob (grep -Eo '[A-Za-z0-9+/]100,' file.txt | base64 -d > payload.bin) and scan the resulting binary. |
| Missing or mismatched PGP signature (signature.asc absent or doesn’t verify) | Reduces confidence that the bundle is authentic. | Run gpg --verify signature.asc <file> (you’ll need the author’s public key). |
| Metadata reveals timestamps (e.g., a document dated 2023‑07‑01 but the ZIP was uploaded in 2025) | May indicate that the material was fabricated or repackaged. | Note it in your write‑up; cross‑reference with known timelines. | Below is a copy‑and‑paste ready script (with comments)
When you finish the analysis, a clear, reproducible report helps both you and anyone else who may read it later.
| Action | Command/Tool | Result |
|--------|--------------|--------|
| Hash check | shasum -a 256 file.zip | Confirms integrity |
| Virus scan | Upload to VirusTotal or run clamscan -r file.zip | Detects known malware |
| List archive contents | 7z l file.zip | Shows hidden files |
| Extract safely | 7z x file.zip -o/tmp/extracted | Unpacks in isolated folder |
| Metadata dump | exiftool *.pdf | Shows creation info |
| Search for strings | strings -a * | grep -i "project" | Finds hidden text |
| Check for PGP | gpg --verify file.sig file | Verifies digital signature |
| Stego check | steghide extract -sf image.jpg (if password known) | Reveals hidden payloads | What the script does for you
