  • The Sentry vulnerability can be restricted in scope to only mobile application (APP) users and restricted in time to a window of 7 days (28th of July to 2nd of August 2022).
  • The following diagram describes the container setup for the Slope Wallet application:
  • The private keys of a total of 6,811 unique wallets (0.4% of the Slope user base on mobile) were found on the Sentry database. Out of these, only 1,444 belonged to the 9,229 affected Solana wallets (15%).
  • Data forensics have uncovered no evidence that the remaining 7,785 wallets drained during the hack were ever stored on the Sentry database.
