Python: `source` parameter not URL-encoded +**File:** `thunderstorm-collector.py`, line ~148 +```python +source = f"?source={args.source}" +``` +**Impact:** Source names with spaces, `&`, `#`, or other URL-special characters will corrupt the +query string or silently truncate the source value at the server. + +**Compare:** The bash collector has `urlencode()`, the Go collector uses `url.QueryEscape()`, +PowerShell uses `[uri]::EscapeDataString()`. Python is the only one missing this. + +**Fix:** +```python +from urllib.parse import quote +source = f"?source={quote(args.source)}" +``` + +--- + +### 2. Python: `Content-Disposition` filename not sanitized +**File:** `thunderstorm-collector.py`, `submit_sample()` +```python +f'Content-Disposition: form-data; name="file"; filename="{filepath}"\r\n' +``` +**Impact:** Filenames containing `"`, `\r`, `\n`, or `;` will break the multipart header, +causing malformed requests or server-side parse errors. The same filepath is inserted raw. + +**Compare:** Bash has `sanitize_filename_for_multipart()`. Python and Perl do not sanitize. + +**Fix:** +```python +safe = filepath.replace('"', '_').replace(';', '_').replace('\\', '/') +``` + +--- + +### 3. Python: `num_submitted` incremented even on failure +**File:** `thunderstorm-collector.py`, `submit_sample()`, line ~100 +```python +# Inside the retry loop, after conn.request(): +... +global num_submitted +num_submitted += 1 # ← This runs even if all retries failed +``` +**Impact:** The final "Submitted" count is inflated β€” every file that enters `submit_sample()` +is counted, regardless of whether it was actually accepted. Makes monitoring/reporting unreliable. + +**Compare:** Bash only increments on `submit_file` returning 0. Go tracks success/failure separately. + +**Fix:** Move the increment inside the `elif resp.status == 200: break` branch. + +--- + +### 4. Python: `os.chdir()` in `process_dir()` is dangerous +**File:** `thunderstorm-collector.py`, `process_dir()` +```python +os.chdir(workdir) +... +os.chdir(startdir) +``` +**Impact:** `os.chdir()` changes the process-global working directory. If an exception occurs +between the two `chdir()` calls, the CWD is left in an arbitrary directory. Also makes the +function non-thread-safe (though single-threaded currently). If `workdir` disappears mid-walk +(temp files), the function will crash and orphan the CWD. + +**Compare:** Bash uses `find -print0` (no chdir). Go uses `filepath.Walk()`. Perl also uses +`chdir()` with the same risk. + +**Fix:** Use `os.path.join()` with absolute paths instead of `chdir()`. Or use `os.scandir()`/ +`os.walk()` which don't require changing CWD. + +--- + +### 5. Perl: String comparison used for numeric size check +**File:** `thunderstorm-collector.pl`, line ~100 +```perl +if ( ( $size / 1024 / 1024 ) gt $max_size ) { +``` +**Impact:** `gt` is the string comparison operator, not numeric. This does lexicographic +comparison: `"9" gt "10"` is **true** (because `"9"` > `"1"` lexically). So a 9MB file +would be skipped with `max_size=10`. Files between 1-9 MB would be incorrectly compared +against multi-digit limits. + +**Fix:** +```perl +if ( ( $size / 1024 / 1024 ) > $max_size ) { +``` + +--- + +### 6. Perl: String comparison for age check +**File:** `thunderstorm-collector.pl`, line ~107 +```perl +if ( $mdate lt ( $current_date - ($max_age * 86400) ) ) { +``` +**Impact:** Same issue β€” `lt` is string comparison. Works coincidentally for large epoch +timestamps (since they're all the same length currently), but will break in edge cases +and is semantically wrong. + +**Fix:** +```perl +if ( $mdate < ( $current_date - ($max_age * 86400) ) ) { +``` + +--- + +### 7. Perl: `source` parameter not URL-encoded +**File:** `thunderstorm-collector.pl`, line ~47 +```perl +$source = "?source=$source"; +``` +**Impact:** Same as Python bug #1. Source names with spaces or special characters corrupt the URL. + +**Fix:** +```perl +use URI::Escape; +$source = "?source=" . uri_escape($source); +``` +Or without additional module: +```perl +$source =~ s/([^A-Za-z0-9\-_.~])/sprintf("%%%02X", ord($1))/ge; +$source = "?source=$source"; +``` + +--- + +### 8. Perl: `num_submitted` incremented even on failure +**File:** `thunderstorm-collector.pl`, `submitSample()`, line ~127 +```perl +$num_submitted++; +``` +**Impact:** Incremented inside the eval block after `$ua->post()`, but before checking +`$req->is_success`. Also incremented even if the request threw an exception caught by +`eval`. The final count is inflated. + +**Fix:** Only increment when `$successful` is true: +```perl +if ($successful) { + $num_submitted++; + last; +} +``` + +--- + +### 9. Python: `retry_time` from header is a string, passed to `sleep()` without conversion +**File:** `thunderstorm-collector.py`, `submit_sample()` +```python +retry_time = resp.headers.get("Retry-After", 30) +time.sleep(retry_time) +``` +**Impact:** `resp.headers.get()` returns a **string** (e.g. `"30"`). `time.sleep()` accepts +a string in Python 3 and will raise `TypeError`. The fallback value `30` is an int and would +work, but the actual header value will crash. + +**Fix:** +```python +retry_time = int(resp.headers.get("Retry-After", 30)) +``` + +--- + +### 10. Python: `--port` has no default value +**File:** `thunderstorm-collector.py`, argparse definition +```python +parser.add_argument("-p", "--port", help="Port of the THOR Thunderstorm server. (Default: 8080)") +``` +**Impact:** Despite the help text saying "Default: 8080", no `default=` is set. If `--port` +is omitted, `args.port` is `None`, and the URL becomes `http://server:None/api/checkAsync`. +The HTTP connection will fail with a confusing error. + +**Fix:** +```python +parser.add_argument("-p", "--port", type=int, default=8080, ...) +``` + +--- + +## 🟑 Inconsistencies Between Collectors + +### 11. Filename in multipart: basename vs full path +| Collector | Filename sent | +|-----------|---------------| +| **Bash** (fixed) | Full path (`/usr/sbin/nft`) | +| **Go** | Full path (`filepath.Abs`) | +| **Python** | Full path (but unsanitized) | +| **Perl** | Basename only (LWP::UserAgent default) | +| **PowerShell** | Full path (`$_.FullName`) | +| **Batch** | Relative path (`%%F` from `FOR /R .`) | + +The Perl collector uses `LWP::UserAgent->post()` with `[ "file" => [ $filepath ] ]`, but +LWP sends only the basename by default. This means the server audit log loses the original path. + +**Fix for Perl:** +```perl +Content => [ "file" => [ $filepath, $filepath ] ], +# Second arg to arrayref is the filename override +``` + +--- + +### 12. Max-age defaults vary wildly +| Collector | Default max-age | +|-----------|----------------| +| Bash | 14 days | +| Go | none (all files) | +| Python | 14 days | +| Perl | **3 days** | +| PowerShell | **0** (disabled) | +| Batch | **30 days** | + +Not necessarily a bug, but worth harmonizing. A 3-day default in Perl is very aggressive +and will miss most files in forensic scenarios. + +--- + +### 13. Max-size defaults vary +| Collector | Default max-size | +|-----------|-----------------| +| Bash | 2 MB | +| Go | 100 MB | +| Python | 20 MB | +| Perl | 10 MB | +| PowerShell | 20 MB | +| Batch | ~3 MB | + +The Go collector is 50x more generous than bash. Forensic users scanning for large +executables may miss files with the script collectors. + +--- + +### 14. Retry behavior varies +| Collector | 503 retry | Error retry | Backoff | +|-----------|-----------|-------------|---------| +| Bash | Yes (Retry-After) | 3 retries, exp backoff | 2Γ—2^n | +| Go | Yes (Retry-After) | 3 retries, exp backoff | 4Γ—2^n | +| Python | Yes (but crashes, bug #9) | 3 retries, exp backoff | 2Γ—2^n | +| Perl | No 503 handling | 4 retries, exp backoff | 2Γ—2^n | +| PowerShell | Yes (Retry-After) | 3 retries, exp backoff | 2Γ—2^n | +| Batch | **No retry at all** | No | No | + +**Perl** doesn't handle HTTP 503 at all β€” it will count a 503 as a "success" because +`$req->is_success` is false but `$num_submitted` is incremented anyway (bug #8), and +it doesn't sleep or retry. + +--- + +## πŸ”΅ Hardening Opportunities + +### 15. Python: No validation of CLI arguments +No checks for empty server, invalid port, negative max-age, etc. Contrast with bash +which validates all numeric params. + +### 16. Perl: No `--max-age` or `--max-size` CLI flags +These are hardcoded variables (`$max_age = 3`, `$max_size = 10`) with no command-line +override. Users must edit the script to change them. + +### 17. Perl: `chdir()` without error recovery +Same as Python bug #4. If `chdir` fails partway through recursion, the CWD is corrupted +for all subsequent operations. The `chdir($startdir) or die` at the end of the loop is +inside the foreach, not a finally/cleanup block. + +### 18. Python: `os.listdir()` instead of `os.walk()` +The manual recursion with `os.listdir()` + `os.chdir()` reimplements what `os.walk()` does +safely. Switching would eliminate bug #4 and simplify the code. + +### 19. Batch: Fire-and-forget uploads (`START /B curl`) +```batch +START /B curl -F file=@%%F ... -o nul -s ... +``` +Uploads run as background processes with output discarded. No error checking, no retry, +no submission count. If the server is down, every upload silently fails. + +### 20. PowerShell: Extensions hardcoded in script body, overwriting parameter +```powershell +param( ... [string[]]$Extensions ... ) +# Then later in "Presets": +[string[]]$Extensions = @('.asp','.vbs', ...) # Overwrites the param! +``` +The parameter `$Extensions` from the command line is **overwritten** by the preset +assignment on line ~117. Users cannot actually filter by extension via the CLI. + +### 21. PowerShell: Infinite retry on 503 +```powershell +while ( $($StatusCode) -ne 200 ) { + ... + if ( $StatusCode -eq 503 ) { + # sleeps and retries forever + } +} +``` +There's no retry limit for 503. If the server is permanently overloaded, the collector +hangs on a single file indefinitely.
