Kroll Data Breach Compromises FTX, BlockFi Customer Information

  • A cyber security incident at bankruptcy service provider Kroll has resulted in the exposure of “non-sensitive” customer data for claimants involved in the FTX and BlockFi cases.
  • Both companies confirmed that account passwords, systems, and funds remained safe, but warned customers to be on the lookout for phishing scams.


Bankrupt cryptocurrency exchange FTX has warned customers to be on the lookout for phishing attempts due to a security breach involving its bankruptcy case claims agent Kroll, the company said via X (formerly Twitter) on 25 August.

According to the announcement, an “unauthorized third party” was able to shortly gain access to “non-sensitive customer data of certain claimants in the pending bankruptcy case” that was handled by Kroll, its current bankruptcy service provider. FTX assured the public that account passwords, systems, and funds remained unaffected, but still warned customers to be on the lookout for scammers.

The bankrupt crypto exchange also noted that Kroll assured FTX that it “promptly contained and remediated” the incident, and that it is closely monitoring the situation. The bankruptcy service provider is also presently informing individuals impacted by the event about the steps they could take for their own protection.

FTX was not the only crypto company to be affected by the cybersecurity incident, with bankrupt crypto lender BlockFi notifying users that its client data was also leaked. Reports of customers receiving fraudulent emails started to appear not long after the incident, with blockchain investigator ZachXBT reporting that customer personal information was compromised.
