Brinztech Alert: The Alleged Database of 3Commas is Leaked

Dark Web News Analysis

The dark web news reports a potentially critical data breach involving 3Commas, a popular automated cryptocurrency trading platform. A threat actor on a hacker forum is claiming to have leaked a database containing sensitive user information.

The compromised dataset reportedly includes Usernames, Passwords, and most critically, API Keys used to connect the platform to major cryptocurrency exchanges. While the full scope is being verified, the presence of API keys makes this a “Class A” threat, as it potentially grants attackers control over funds stored on third-party exchanges (such as Binance, Coinbase, or Kraken) without needing to access the exchanges directly.

Key Cybersecurity Insights

Breaches of trading automation tools differ from standard data leaks because they compromise the “keys to the castle” for external financial accounts:

• The API Key “Kill Chain”:

The most severe risk is the exposure of API Keys and Secrets. These keys allow the 3Commas software to execute trades on the user’s behalf. If leaked, attackers can use these keys to remotely execute unauthorized trades on the victim’s exchange account—often buying a low-liquidity coin to pump the price and drain the victim’s balance (“Counter-Trading”).

• Withdrawal Risk: While most users disable withdrawal permissions on their API keys, any keys that were set to “Enable Withdrawals” (often done for arbitrage bots) could allow attackers to immediately drain the entire balance of the connected exchange account to an external wallet.
• Credential Stuffing: The leak of Usernames and Passwords poses a secondary risk. If users reused these credentials, attackers can log into the 3Commas dashboard directly to view trading strategies, modify bot settings, or harvest personal data.
• Trust & Supply Chain: This incident highlights the risk of Third-Party Integrations. Even if a user’s Binance account is secure with MFA, a compromised third-party tool (3Commas) with API access bypasses those login protections entirely.

Mitigation Strategies

To protect your digital assets and exchange accounts, the following strategies are recommended:

• Revoke & Re-Generate: Immediate action is required. Do not wait for confirmation. Go to every exchange connected to 3Commas (Binance, Bybit, etc.) and Delete/Revoke all existing API keys. Generate new keys only after the platform confirms it is safe.
• Enable IP Whitelisting: When creating new API keys, strictly enforce IP Whitelisting. This ensures that the keys can only be used from specific IP addresses (e.g., 3Commas’ official IPs), preventing attackers from using them even if they are stolen.
• Password Rotation: Change your 3Commas password immediately and enable Multi-Factor Authentication (MFA/2FA) using an authenticator app (not SMS).
• Audit Trade History: Check your exchange transaction logs for any trades you did not authorize, particularly involving obscure or low-volume altcoins.
