The Capital Link Breach Gave Hackers 25,710 Financial Site Logins

HEROIC analysts identified a database breach affecting Capital Link, a now-defunct U.S.-based financial platform. The breach is dated to August 21, 2018, and exposed 25,710 records, including email addresses and plaintext passwords, which were shared on a hacking forum.

What Attackers Can Do With the Capital Link Data

Because Capital Link operated in the financial sector, the accounts tied to these credentials likely touched money in some way, whether investment tools, account dashboards, or related services. With the password stored in plaintext, an attacker does not need to crack anything, they can log in directly. If the same password was used on a bank, brokerage, or payment account, an attacker has everything needed to attempt to drain or take over that account.

What Was Exposed in the Capital Link Breach

• Email addresses
• Plaintext passwords

Why This Matters

Financial-adjacent breaches like this one are especially attractive for credential stuffing, where attackers test leaked email and password pairs against banking and payment sites specifically. Anyone who reused a Capital Link password on a financial account faces a real risk of account takeover, identity theft, or direct financial fraud.

How a Database and Combolist Breach Spreads

This incident is classified as a database and combolist breach. The original data was pulled from Capital Link's systems and later repackaged into a combolist, a file pairing emails with passwords that attackers can plug directly into automated login tools, and traded on hacking forums.
