Source documentation, not instructions for this website. Review permissions before running any commands.
Use this skill BEFORE capturing any screenshot, exporting any HAR, or attaching any evidence to a bug-bounty submission. It catches the most common evidence-hygiene mistakes that cause cookies to leak, PII to be shared without consent, or screenshots to be unsuitable for triage.
The core principle: Bug-bounty evidence is meant to convince a triager. Anything beyond that — live cookies, real-user PII, internal trace IDs that aren't useful — should not be in the evidence.
Every PoC artifact (screenshot, HAR, raw HTTP request, terminal transcript) potentially contains data that needs different treatment.
| Category | Examples | Treatment |
|---|---|---|
| Your-account secrets | Session cookies, OAuth tokens, refresh tokens, API keys | Always redact. Even in private bug-bounty platform attachments. Your account, your session — protect it. |
| Other users' PII | Real names, emails, phone numbers, addresses, profile photos, account IDs | Redact unless explicitly demonstrating cross-account impact. Even then, mask faces and minimize the data you display. |
| Triager-useful metadata | Trace IDs (x-datadog-trace-id), request IDs, server timestamps, your test account UID/email, GraphQL operation names, response shapes | Leave visible — these help the triager correlate to logs and reproduce. |
| Test-account passwords (limited use) | Throwaway passwords on a test account (e.g., Testing@5678) | Acceptable in screenshots if you rotate immediately after submission so the value shown is dead. Don't leave real-use passwords in evidence. |

Method C — Find/replace in raw text (for HAR files, terminal transcripts)
Before clicking Capture:
[ ] Network tab Headers panel is collapsed or out of frame
[ ] Burp's Request panel is hidden behind the divider drag
[ ] No "Copy as cURL" output is visible on screen
[ ] DevTools Application → Storage → Cookies tab is closed
[ ] Browser URL bar doesn't show a session token in query string (rare but possible)
After capturing:
[ ] Open the screenshot at full resolution before saving
[ ] Search for the session cookie name substring in any visible text — if present, redact
[ ] Search for the literal first 6 chars of your cookie value — if present, redact
[ ] Compare to the previous PoC screenshot in the same engagement — same redaction discipline
When a PoC necessarily exposes another user's data (e.g., demonstrating IDOR by showing the victim's email in an attacker-session response), redact the actual PII even in private attachments.
"first_name": "<REDACTED>")Bad (leaks victim's full PII):
{"data":{"contact":{"first_name":"Nadene","last_name":"Afton","email":"nadene.afton@example.com","phone":"+1-555-867-5309"}}}
Good (proves the bug, masks the PII):
{"data":{"contact":{"first_name":"<REDACTED — real first name>","last_name":"<REDACTED — real last name>","email":"<REDACTED>@example.com","phone":"<REDACTED>"}}}
In screenshot form, black-bar each value with a rectangle annotation labeled "REAL PII REDACTED" if there's space.
Reference the redaction explicitly:
## Proof of Concept
The screenshot below demonstrates the IDOR. The attacker session (uid 12345678) successfully retrieves the victim's profile data (uid 99887766). **Real PII fields in the response are masked with black rectangles to limit unauthorized exposure of victim data, per responsible-disclosure hygiene.** The unredacted response is available privately on request.
This signals the triager that you're disciplined and gives them a clear path to the unredacted version if they need it for verification.
HAR (HTTP Archive) files are JSON dumps of network traffic with full request/response bodies and headers. They include cookies, auth tokens, and any PII that was in transit.
Chrome DevTools → Network tab → right-click anywhere in the request list → "Save all as HAR with content"
Use jq to strip sensitive headers. Save this as a shell function or one-liner you can re-use:
sanitize_har() {
local input="$1"
local output="${1%.har}.sanitized.har"
jq '
.log.entries |= map(
(.request.headers |= map(
if .name | ascii_downcase | IN("cookie", "authorization", "x-csrf-token") then .value = "<REDACTED>" else . end
)) |
(.response.headers |= map(
if .name | ascii_downcase | IN("set-cookie") then .value = "<REDACTED>" else . end
)) |
(.request.cookies |= map(.value = "<REDACTED>")) |
(.response.cookies |= map(.value = "<REDACTED>"))
)
' "$input" > "$output"
echo "Sanitized: $output"
}
Usage:
sanitize_har /path/to/exported.har
# Output: /path/to/exported.sanitized.har
# Check that no Cookie or Authorization values are leaking
grep -i 'authn\|"cookie"\|authorization' /path/to/exported.sanitized.har | head -20
If you see your real cookie value in the output, the sanitization missed something — fix the jq filter for that specific field name.
If the HAR captured cross-account data (e.g., during an IDOR demo), additionally strip the response body fields that contain victim PII. Add to the jq filter:
(.response.content.text |= (
if . then
(fromjson? // .) | tostring | gsub("real.first.name.example"; "<REDACTED>")
else . end
))
Customize the gsub patterns to your specific captured data.
The Results window is the strongest evidence for rate-limit findings. To capture cleanly:
Request#, Payload, Status code, Response received, LengthAlmost never the right screenshot — it shows entire request/response pairs with cookies. Use Repeater for demos instead.
The Scanner tab's Issues panel is generally safe to screenshot — it shows finding summaries without the underlying request bodies. Click into a specific finding before screenshotting only if you've redacted its evidence first.
fetch('/api/endpoint', {
method: 'POST',
headers: {'content-type': 'application/json'},
credentials: 'include', // sends cookies automatically — they won't appear in your code
body: JSON.stringify({ /* your payload */ })
}).then(r => r.json()).then(j => console.log("LABEL:", JSON.stringify(j)))
Why this is clean:
credentials: 'include' means the browser sends cookies. Your code never references them. They never appear in screenshots.console.log("LABEL:", ...) produces a labeled output line you can search for in the screenshotJSON.stringify(j) formats the response on a single line — easier to crop tightlyFor a 4-step PoC (verify before / change / verify after / revert), clear the console between calls so each screenshot only shows ONE call and ONE response:
Cmd+KCtrl+LTake the screenshot immediately after the response prints — don't wait for unrelated framework warnings to appear.

# EVIDENCE HYGIENE — PoC Capture & Redaction Discipline
> Use this skill BEFORE capturing any screenshot, exporting any HAR, or attaching any evidence to a bug-bounty submission. It catches the most common evidence-hygiene mistakes that cause cookies to leak, PII to be shared without consent, or screenshots to be unsuitable for triage.
The core principle: **Bug-bounty evidence is meant to convince a triager. Anything beyond that — live cookies, real-user PII, internal trace IDs that aren't useful — should not be in the evidence.**
---
## 1. Two Categories of Sensitive Data
Every PoC artifact (screenshot, HAR, raw HTTP request, terminal transcript) potentially contains data that needs different treatment.
| Category | Examples | Treatment |
|---|---|---|
| **Your-account secrets** | Session cookies, OAuth tokens, refresh tokens, API keys | Always redact. Even in private bug-bounty platform attachments. Your account, your session — protect it. |
| **Other users' PII** | Real names, emails, phone numbers, addresses, profile photos, account IDs | Redact unless explicitly demonstrating cross-account impact. Even then, mask faces and minimize the data you display. |
| **Triager-useful metadata** | Trace IDs (`x-datadog-trace-id`), request IDs, server timestamps, your test account UID/email, GraphQL operation names, response shapes | **Leave visible** — these help the triager correlate to logs and reproduce. |
| **Test-account passwords (limited use)** | Throwaway passwords on a test account (e.g., `Testing@5678`) | Acceptable in screenshots if you rotate immediately after submission so the value shown is dead. Don't leave real-use passwords in evidence. |
---
## 2. Cookie Redaction Protocol
### 2.1 What must be masked
The session cookie value is the highest-value secret in any PoC. Mask:
- The session cookie (`authn`, `session`, `sid`, `__Secure-id`, etc. — name varies per target)
- `csrf-token` if it's bound to your session
- `Authorization` headers (Bearer tokens, JWT)
- `Cookie` request header values for any session-bearing cookie
- `Set-Cookie` response header values for any session-bearing cookie
### 2.2 What's safe to leave visible
- Cloudflare cookies (`__cf_bm`, `_cfuvid`) — these are bot-management, not session-bearing
- Analytics cookies (`ajs_anonymous_id`, `_ga`)
- Trace correlation IDs (`x-datadog-trace-id`, `x-request-id`)
- Server / framework headers (`Server: cloudflare`, `X-Frame-Options`)
- Your test account email/UID (per Bugcrowdninja alias section in `bugcrowd-reporting`)
### 2.3 Redaction methods (ranked by practicality)
**Method A — Don't capture the cookies in the first place** (preferred when possible)
- For DevTools Console PoCs: use `credentials: 'include'` so the browser sends cookies automatically. Console output won't echo the cookie. Screenshot the Console output, never the Network tab Headers panel.
- For Burp Repeater PoCs: drag the bottom request/response panel divider DOWN to hide the request body before screenshotting. Capture only the Results table for Intruder runs.
**Method B — Black-bar in image editor** (when capture inevitably includes cookies)
- macOS: Open screenshot in Preview → Tools → Annotate → Rectangle → set fill color to black → drag rectangle over the cookie value → save
- Windows: Use Snip & Sketch's annotation tools or any image editor (Paint.NET, etc.)
- Burp itself: in Burp's Proxy → Match and Replace, you can pre-emptively redact cookie values to placeholder strings before screenshotting
**Method C — Find/replace in raw text** (for HAR files, terminal transcripts)
- See §4 for the jq commands
### 2.4 Pre-screenshot checklist
Before clicking Capture:
```
[ ] Network tab Headers panel is collapsed or out of frame
[ ] Burp's Request panel is hidden behind the divider drag
[ ] No "Copy as cURL" output is visible on screen
[ ] DevTools Application → Storage → Cookies tab is closed
[ ] Browser URL bar doesn't show a session token in query string (rare but possible)
```
After capturing:
```
[ ] Open the screenshot at full resolution before saving
[ ] Search for the session cookie name substring in any visible text — if present, redact
[ ] Search for the literal first 6 chars of your cookie value — if present, redact
[ ] Compare to the previous PoC screenshot in the same engagement — same redaction discipline
```
---
## 3. PII Black-Bar Protocol
When a PoC necessarily exposes another user's data (e.g., demonstrating IDOR by showing the victim's email in an attacker-session response), redact the actual PII even in private attachments.
### 3.1 What to mask (other-user data)
- First name, last name (full or partial)
- Email address (mask the local part; can leave domain if non-identifying)
- Phone number (mask the last 7 digits, optionally leave country code)
- Physical address (mask everything below city)
- Date of birth (mask the year, optionally the month)
- Government IDs (SSN, passport — mask everything)
- Profile photos / face images (black-bar the face entirely)
- Account IDs that the user could correlate to public profiles
### 3.2 What to leave visible (proves the bug, not the user)
- The fact that the field was returned (the JSON key name)
- The shape / type of the field (`"first_name": "<REDACTED>"`)
- Your own (attacker session's) UID / email — this proves cross-account
- The endpoint URL and request method
- The trace ID
### 3.3 Worked example — IDOR PoC body
**Bad (leaks victim's full PII):**
```json
{"data":{"contact":{"first_name":"Nadene","last_name":"Afton","email":"nadene.afton@example.com","phone":"+1-555-867-5309"}}}
```
**Good (proves the bug, masks the PII):**
```json
{"data":{"contact":{"first_name":"<REDACTED — real first name>","last_name":"<REDACTED — real last name>","email":"<REDACTED>@example.com","phone":"<REDACTED>"}}}
```
In screenshot form, black-bar each value with a rectangle annotation labeled "REAL PII REDACTED" if there's space.
### 3.4 In the report body
Reference the redaction explicitly:
```markdown
## Proof of Concept
The screenshot below demonstrates the IDOR. The attacker session (uid 12345678) successfully retrieves the victim's profile data (uid 99887766). **Real PII fields in the response are masked with black rectangles to limit unauthorized exposure of victim data, per responsible-disclosure hygiene.** The unredacted response is available privately on request.
```
This signals the triager that you're disciplined and gives them a clear path to the unredacted version if they need it for verification.
---
## 4. HAR File Sanitization
HAR (HTTP Archive) files are JSON dumps of network traffic with full request/response bodies and headers. They include cookies, auth tokens, and any PII that was in transit.
### 4.1 Generate the HAR
Chrome DevTools → Network tab → right-click anywhere in the request list → "Save all as HAR with content"
### 4.2 Sanitize before attaching
Use `jq` to strip sensitive headers. Save this as a shell function or one-liner you can re-use:
```bash
sanitize_har() {
local input="$1"
local output="${1%.har}.sanitized.har"
jq '
.log.entries |= map(
(.request.headers |= map(
if .name | ascii_downcase | IN("cookie", "authorization", "x-csrf-token") then .value = "<REDACTED>" else . end
)) |
(.response.headers |= map(
if .name | ascii_downcase | IN("set-cookie") then .value = "<REDACTED>" else . end
)) |
(.request.cookies |= map(.value = "<REDACTED>")) |
(.response.cookies |= map(.value = "<REDACTED>"))
)
' "$input" > "$output"
echo "Sanitized: $output"
}
```
Usage:
```bash
sanitize_har /path/to/exported.har
# Output: /path/to/exported.sanitized.har
```
### 4.3 Verify before attaching
```bash
# Check that no Cookie or Authorization values are leaking
grep -i 'authn\|"cookie"\|authorization' /path/to/exported.sanitized.har | head -20
```
If you see your real cookie value in the output, the sanitization missed something — fix the jq filter for that specific field name.
### 4.4 Remove other-user PII (if applicable)
If the HAR captured cross-account data (e.g., during an IDOR demo), additionally strip the response body fields that contain victim PII. Add to the jq filter:
```jq
(.response.content.text |= (
if . then
(fromjson? // .) | tostring | gsub("real.first.name.example"; "<REDACTED>")
else . end
))
```
Customize the gsub patterns to your specific captured data.
---
## 5. Burp Suite Screenshot Hygiene
### 5.1 Repeater (single request demo)
1. In the Repeater request panel, the Cookie header is on its own line — drag the panel divider DOWN to hide everything below the request line / target line
2. Or: temporarily delete the Cookie header text from the Repeater pane (it doesn't affect the original captured request) before screenshotting, then restore
3. Capture only the response panel (right side) showing the JSON / HTML response that demonstrates the bug
### 5.2 Intruder Results table (rate-limit / brute-force demos)
The Results window is the strongest evidence for rate-limit findings. To capture cleanly:
1. After the attack finishes, drag the horizontal divider between the Results table and the Request/Response panels DOWN, until only the Results table is visible
2. Screenshot only the columns: `Request#`, `Payload`, `Status code`, `Response received`, `Length`
3. Don't include the Request / Response sub-panels — they contain the cookie
### 5.3 Proxy HTTP history (capture demo)
Almost never the right screenshot — it shows entire request/response pairs with cookies. Use Repeater for demos instead.
### 5.4 Scanner findings (if applicable)
The Scanner tab's Issues panel is generally safe to screenshot — it shows finding summaries without the underlying request bodies. Click into a specific finding before screenshotting only if you've redacted its evidence first.
---
## 6. Chrome DevTools Console PoC Patterns
### 6.1 The clean-PoC pattern
```js
fetch('/api/endpoint', {
method: 'POST',
headers: {'content-type': 'application/json'},
credentials: 'include', // sends cookies automatically — they won't appear in your code
body: JSON.stringify({ /* your payload */ })
}).then(r => r.json()).then(j => console.log("LABEL:", JSON.stringify(j)))
```
Why this is clean:
- `credentials: 'include'` means the browser sends cookies. Your code never references them. They never appear in screenshots.
- `console.log("LABEL:", ...)` produces a labeled output line you can search for in the screenshot
- `JSON.stringify(j)` formats the response on a single line — easier to crop tightly
### 6.2 Multi-step PoCs (clear console between calls)
For a 4-step PoC (verify before / change / verify after / revert), clear the console between calls so each screenshot only shows ONE call and ONE response:
- Mac: `Cmd+K`
- Windows / Linux: `Ctrl+L`
Take the screenshot immediately after the response prints — don't wait for unrelated framework warnings to appear.
### 6.3 Long responses (tSkill source recorded
