A threat actor has allegedly breached the UK-based electronic signature provider, SignitOnline[.]co[.]uk, and is attempting to sell the company’s data on a dark web forum. SignitOnline[.]co[.]uk offers services that allow users to sign documents digitally, making the nature of the compromised data particularly sensitive. The seller claims the breach, dated July 2025, affects 5,000 users and includes a massive 36.5 GB of user signature files.
The threat actor is selling the data for $500 USD and has provided samples, including database credentials, to substantiate their claims. The compromised information allegedly includes highly sensitive user details. If the claims are true, this data could be used for identity theft, fraud, and sophisticated phishing campaigns against the company’s users.
The allegedly leaked data includes:
- Email Addresses
- Plaintext Passwords
- Account Registration Dates
- Complete SQL Dump
- 36.5 GB of User Signature Files
