1. WHAT ARE COMBOS AND WHY THEY MATTER
A combo list is a database of stolen credentials. It contains email
assword pairs, username
assword pairs, or full account details extracted from data breaches. Combo lists are the raw material for credential stuffing attacks and account cracking.
Why combo lists matter:
- They give you access to thousands of accounts without creating them
- Cracked accounts sell for $1-$50 each depending on the platform
- A single good combo list can generate thousands of dollars
- They are the foundation of the "cracking" underground economy
- Low barrier to entry (anyone with a computer can start)
- Scalable (check 50,000+ combos per day with proper setup)
Types of Combo Lists:
- Email
assword (E
): Most common format. Email and password separated by colon.
- User
ass (U
): Username and password pairs.
- Fullz: Complete identity information (name, email, password, DOB, SSN, address).
- Cookies: Stolen session cookies that bypass login entirely.
- Tokens: API tokens or access tokens for specific services.
- Phone
assword: Phone number and password pairs (for SMS-based services).
Combo List Economics:
- Raw combo lists: $5-$50 per million lines
- Fresh combo lists (2026): $50-$200 per million lines
- Checked/live accounts: $1-$50 per account
- Profit margin: 100-1000% depending on freshness and platform
Pro Tip: Not all combo lists are created equal. A list from a 2024 breach might have a 2-5% hit rate. A list from a 2026 breach might have a 20-40% hit rate. Freshness is everything in the combo game.
[HR=2][/HR]
2. COMBO LIST FORMATS EXPLAINED
Basic Format (Email
assword):
This is the most common format. The checker tool tries each email
assword pair on the target platform.
Extended Format (Email
assword:Name):
Some lists include the account holder's name for additional verification.
Full Format (Fullz):
Fullz include personal information. Used for identity theft and bank account access.
Cookie Format:
Cookies bypass the login entirely. They are worth 10-50x more than email
assword pairs.
Token Format:
API tokens give direct access to account data without going through the login page.
Phone
assword Format:
Used for SMS-based services like WhatsApp, Telegram, banking apps.
Header:Value Format:
Most comprehensive format. Used for high-value targets.
[HR=2][/HR]
3. WHERE COMBO LISTS COME FROM
Combo lists are sourced from data breaches. Here is how they are created:
Method 1 - Database Breaches:
Hackers gain access to company databases and extract user credentials. These are the largest and freshest combo lists.
- Forums and message boards (phpBB, vBulletin, XenForo)
- E-commerce sites (customer databases)
- Gaming platforms (user accounts)
- Social media platforms (user credentials)
Method 2 - Phishing:
Fake login pages capture credentials from unsuspecting users. These are often high-quality because users enter real passwords.
- Email phishing campaigns
- SMS phishing (smishing)
- Social media phishing
- cloned websites
Method 3 - Infostealer Malware:
Malware like RedLine, Raccoon, or Vidar steals saved passwords from browsers. These contain passwords for dozens of sites per victim.
- RedLine Stealer - Most popular infostealer
- Raccoon Stealer - Close second
- Vidar - Newer, gaining popularity
- Redline/Raccoon logs contain: browser saved passwords, cookies, crypto wallets, autofill data
Method 4 - Credential Stuffing:
Combining leaked databases from multiple breaches. Cross-referencing emails across platforms to build comprehensive profiles.
- Cross-platform password reuse
- Email aggregation from multiple breaches
- Password pattern analysis
Method 5 - SIM Swapping:
Taking over phone numbers to receive SMS verification codes. Used to bypass 2FA and access accounts.
- Social engineering carriers
- Insider threats at telecom companies
- SS7 network exploits
Method 6 - Malware/Keyloggers:
Keyloggers capture keystrokes in real-time. Captures passwords as they are typed.
- Hardware keyloggers (physical devices)
- Software keyloggers (Remote Access Trojans)
- Screen recorders
Pro Tip: The freshest combo lists come from recent breaches (within the last 3-6 months). Old lists from 2020-2022 have low hit rates because people have changed their passwords. Always prioritize freshness.
[HR=2][/HR]
4. HOW TO READ AND PARSE A COMBO LIST
Combo lists come in different formats. Here is how to parse them:
Step 1 - Identify the Format:
Look at the first few lines. Is it email
assword? username
assword? Fullz?
Step 2 - Remove Duplicates:
Many combo lists contain duplicate entries. Use a tool to deduplicate:
- Notepad++ with line sort and dedup
- Python script: lines = list(set(open('combos.txt').readlines()))
- Online dedup tools (use with caution - never upload sensitive data)
Step 3 - Filter by Domain:
If you only want Gmail accounts, filter by @gmail.com. This improves checker efficiency.
Step 4 - Validate Format:
Ensure every line has the correct format. Remove blank lines, malformed entries, and corrupted data.
Step 5 - Split into Batches:
Large combo lists should be split into smaller files (10,000-50,000 lines each) for easier checking.
Python Parsing Script:
Common Parsing Issues:
- UTF-8 encoding errors (use errors='ignore')
- Mixed separators (colon, pipe, tab)
- Extra whitespace
- Corrupted lines (partial data)
- Duplicate entries (same email, different passwords)
[HR=2][/HR]

[HR=2][/HR]
10. HOW TO FILTER DEAD COMBOS
Dead combos waste time and resources. Here is how to filter them:
Step 1 - Syntax Check:
Remove lines that do not match email
assword format. Use regex or a simple script.
Step 2 - Domain Filter:
Keep only the email domains you want (gmail.com, yahoo.com, outlook.com, etc.)
Step 3 - Password Filter:
Remove passwords shorter than 6 characters. These are almost always dead.
Step 4 - Duplicate Removal:
Remove exact duplicates and same-email-different-password entries.
Step 5 - Live Check:
Run a small batch (1,000 lines) through the checker to estimate hit rate. If hit rate is below 5%, the list is too old.
Step 6 - Split by Quality:
Separate high-quality combos (from recent breaches) from low-quality ones (from old breaches).
Filtering Script:
[HR=2][/HR]
11. STORE MANAGEMENT - ORGANIZING YOUR LISTS
Organization is critical when working with large combo lists. Here is the system:
Folder Structure:
Naming Convention:
Storage:
- Keep raw lists compressed (.zip, .7z)
- Store live results in encrypted containers
- Use VeraCrypt for sensitive data
- Never store combos on cloud services
- Backup to encrypted USB drives
Database Tracking:
Create a spreadsheet to track:
- List name and source
- Date acquired
- Total lines
- Hit rate per platform
- Revenue generated
- Notes
[HR=2][/HR]
12. THE HIT RATE REALITY CHECK
Here are realistic hit rates for 2026:
Netflix:
- Old list (2023-2024): 3-8%
- Medium list (2025): 8-15%
- Fresh list (2026): 15-30%
Spotify:
- Old list (2023-2024): 5-10%
- Medium list (2025): 10-18%
- Fresh list (2026): 18-35%
Gmail:
- Old list (2023-2024): 10-20%
- Medium list (2025): 20-30%
- Fresh list (2026): 30-50%
Binance (Verified):
- Old list (2023-2024): 1-3%
- Medium list (2025): 3-8%
- Fresh list (2026): 8-15%
Steam:
- Old list (2023-2024): 5-12%
- Medium list (2025): 12-20%
- Fresh list (2026): 20-40%
What This Means:
A 50,000 line Netflix combo list from 2025 will yield approximately 4,000-7,500 live accounts. At $5 each, that is $20,000-$37,500 in potential revenue. But reality check: you need working proxies, a good checker, and time to sell them all.
Revenue Calculator:
Output: Live accounts: 6000, Potential revenue: $30000

1. WHAT ARE COMBOS AND WHY THEY MATTER
A combo list is a database of stolen credentials. It contains email
Why combo lists matter:
- They give you access to thousands of accounts without creating them
- Cracked accounts sell for $1-$50 each depending on the platform
- A single good combo list can generate thousands of dollars
- They are the foundation of the "cracking" underground economy
- Low barrier to entry (anyone with a computer can start)
- Scalable (check 50,000+ combos per day with proper setup)
Types of Combo Lists:
- User
- Fullz: Complete identity information (name, email, password, DOB, SSN, address).
- Cookies: Stolen session cookies that bypass login entirely.
- Tokens: API tokens or access tokens for specific services.
- Phone
Combo List Economics:
- Raw combo lists: $5-$50 per million lines
- Fresh combo lists (2026): $50-$200 per million lines
- Checked/live accounts: $1-$50 per account
- Profit margin: 100-1000% depending on freshness and platform
Pro Tip: Not all combo lists are created equal. A list from a 2024 breach might have a 2-5% hit rate. A list from a 2026 breach might have a 20-40% hit rate. Freshness is everything in the combo game.

3. WHERE COMBO LISTS COME FROM
Combo lists are sourced from data breaches. Here is how they are created:
Method 1 - Database Breaches:
Hackers gain access to company databases and extract user credentials. These are the largest and freshest combo lists.
- Forums and message boards (phpBB, vBulletin, XenForo)
- E-commerce sites (customer databases)
- Gaming platforms (user accounts)
- Social media platforms (user credentials)
Method 2 - Phishing:
Fake login pages capture credentials from unsuspecting users. These are often high-quality because users enter real passwords.
- Email phishing campaigns
- SMS phishing (smishing)
- Social media phishing
- cloned websites
Method 3 - Infostealer Malware:
Malware like RedLine, Raccoon, or Vidar steals saved passwords from browsers. These contain passwords for dozens of sites per victim.
- RedLine Stealer - Most popular infostealer
- Raccoon Stealer - Close second
- Vidar - Newer, gaining popularity
- Redline/Raccoon logs contain: browser saved passwords, cookies, crypto wallets, autofill data
Method 4 - Credential Stuffing:
Combining leaked databases from multiple breaches. Cross-referencing emails across platforms to build comprehensive profiles.
- Cross-platform password reuse
- Email aggregation from multiple breaches
- Password pattern analysis
Method 5 - SIM Swapping:
Taking over phone numbers to receive SMS verification codes. Used to bypass 2FA and access accounts.
- Social engineering carriers
- Insider threats at telecom companies
- SS7 network exploits
Method 6 - Malware/Keyloggers:
Keyloggers capture keystrokes in real-time. Captures passwords as they are typed.
- Hardware keyloggers (physical devices)
- Software keyloggers (Remote Access Trojans)
- Screen recorders
Pro Tip: The freshest combo lists come from recent breaches (within the last 3-6 months). Old lists from 2020-2022 have low hit rates because people have changed their passwords. Always prioritize freshness.

4. HOW TO READ AND PARSE A COMBO LIST
Combo lists come in different formats. Here is how to parse them:
Step 1 - Identify the Format:
Look at the first few lines. Is it email
Step 2 - Remove Duplicates:
Many combo lists contain duplicate entries. Use a tool to deduplicate:
- Notepad++ with line sort and dedup
- Python script: lines = list(set(open('combos.txt').readlines()))
- Online dedup tools (use with caution - never upload sensitive data)
Step 3 - Filter by Domain:
If you only want Gmail accounts, filter by @gmail.com. This improves checker efficiency.
Step 4 - Validate Format:
Ensure every line has the correct format. Remove blank lines, malformed entries, and corrupted data.
Step 5 - Split into Batches:
Large combo lists should be split into smaller files (10,000-50,000 lines each) for easier checking.
Python Parsing Script:
Code:
import re
def parse_combos(input_file, output_file):
with open(input_file, 'r', encoding='utf-8', errors='ignore') as f:
lines = f.readlines()
clean = []
for line in lines:
line = line.strip()
if re.match(r'^[^@]+@[^@]+\.[^@]+:.+$', line):
clean.append(line)
# Remove duplicates
clean = list(set(clean))
with open(output_file, 'w') as f:
f.write('\n'.join(clean))
print(f"Parsed {len(clean)} valid combos from {len(lines)} lines")
parse_combos('raw_combos.txt', 'clean_combos.txt')
Common Parsing Issues:
- UTF-8 encoding errors (use errors='ignore')
- Mixed separators (colon, pipe, tab)
- Extra whitespace
- Corrupted lines (partial data)
- Duplicate entries (same email, different passwords)

10. HOW TO FILTER DEAD COMBOS
Dead combos waste time and resources. Here is how to filter them:
Step 1 - Syntax Check:
Remove lines that do not match email
Step 2 - Domain Filter:
Keep only the email domains you want (gmail.com, yahoo.com, outlook.com, etc.)
Step 3 - Password Filter:
Remove passwords shorter than 6 characters. These are almost always dead.
Step 4 - Duplicate Removal:
Remove exact duplicates and same-email-different-password entries.
Step 5 - Live Check:
Run a small batch (1,000 lines) through the checker to estimate hit rate. If hit rate is below 5%, the list is too old.
Step 6 - Split by Quality:
Separate high-quality combos (from recent breaches) from low-quality ones (from old breaches).
Filtering Script:
Code:
import re
def filter_combos(input_file, output_file, min_password_len=6):
with open(input_file, 'r', encoding='utf-8', errors='ignore') as f:
lines = f.readlines()
filtered = []
for line in lines:
line = line.strip()
parts = line.split(':')
if len(parts) >= 2:
email = parts[0]
password = parts[1]
if re.match(r'^[^@]+@[^@]+\.[^@]+$', email):
if len(password) >= min_password_len:
filtered.append(line)
# Remove duplicates
filtered = list(set(filtered))
with open(output_file, 'w') as f:
f.write('\n'.join(filtered))
print(f"Filtered to {len(filtered)} combos from {len(lines)} lines")
print(f"Removed {len(lines) - len(filtered)} dead/invalid combos")
filter_combos('raw_combos.txt', 'filtered_combos.txt')
[HR=2][/HR]
11. STORE MANAGEMENT - ORGANIZING YOUR LISTS
Organization is critical when working with large combo lists. Here is the system:
Folder Structure:
Code:
/combos
/raw (original, unprocessed lists)
/filtered (deduplicated, formatted)
/checked (results from checkers)
/netflix_live.txt
/spotify_live.txt
/binance_live.txt
/gaming_live.txt
/dead (accounts that failed checking)
/sold (accounts that have been sold)
/configs (checker configs)
/proxies (proxy lists)
Naming Convention:
Code:
platform_breachdate_size.txt
example: netflix_2026-03_50k.txt
Storage:
- Keep raw lists compressed (.zip, .7z)
- Store live results in encrypted containers
- Use VeraCrypt for sensitive data
- Never store combos on cloud services
- Backup to encrypted USB drives
Database Tracking:
Create a spreadsheet to track:
- List name and source
- Date acquired
- Total lines
- Hit rate per platform
- Revenue generated
- Notes
[HR=2][/HR]
12. THE HIT RATE REALITY CHECK
Here are realistic hit rates for 2026:
Netflix:
- Old list (2023-2024): 3-8%
- Medium list (2025): 8-15%
- Fresh list (2026): 15-30%
Spotify:
- Old list (2023-2024): 5-10%
- Medium list (2025): 10-18%
- Fresh list (2026): 18-35%
Gmail:
- Old list (2023-2024): 10-20%
- Medium list (2025): 20-30%
- Fresh list (2026): 30-50%
Binance (Verified):
- Old list (2023-2024): 1-3%
- Medium list (2025): 3-8%
- Fresh list (2026): 8-15%
Steam:
- Old list (2023-2024): 5-12%
- Medium list (2025): 12-20%
- Fresh list (2026): 20-40%
What This Means:
A 50,000 line Netflix combo list from 2025 will yield approximately 4,000-7,500 live accounts. At $5 each, that is $20,000-$37,500 in potential revenue. But reality check: you need working proxies, a good checker, and time to sell them all.
Revenue Calculator:
Code:
combo_lines = 50000
hit_rate = 0.12 # 12% for medium Netflix list
price_per_account = 5
live_accounts = combo_lines * hit_rate
revenue = live_accounts * price_per_account
print(f"Live accounts: {live_accounts}")
print(f"Potential revenue: ${revenue}")
