Trading platform 3Commas has once again come into the spotlight following the disclosure of a security breach on Sunday, affecting a number of user accounts. 

According to the release, the platform received reports from customers about unauthorized trades occurring shortly after their passwords had been reset. 

Following an internal investigation, 3Commas revealed in a blog post that there had been unauthorized access to customer account data. 

The breach is being touted as a limited one, with unauthorized trades being carried out predominantly on accounts of users who had not enabled two-factor authentication (2FA), 3Commas said.

API secret data and account passwords are said not among the compromised information. Blockworks has reached out to learn more.

In response, 3Commas said it has modified its password reset process. The platform claims to have now instituted a policy where all API connections are disabled following a password reset — intended to act as an added security layer. 

Following the incident, the company attempted to reassure its user base that it will continue to “operate in a state of heightened alert.”

The breach on Sunday is reminiscent of an earlier incident in December, where a significant leak led to the API keys of approximately 100,000 3Commas customers being posted publicly by malevolent actors. 

That incident triggered a review of the platform’s security framework, with the company seeking expertise from cybersecurity professionals.

A third related incident in October 2022 prompted former FTX CEO Sam Bankman-Fried, currently on trial for alleged fraud and money laundering charges, to reimburse $6 million to customers affected by a phishing attack.

Multiple security lapses within a year underscore the challenges faced by the trading platform in an ongoing bear market marked by increasing cyber threats.
