According to Foresight News, SlowMist founder Yu Xian tweeted that some private keys and passwords of Seif Wallet were collected by a built-in third-party analysis platform, which was discovered and reported by a white hat hacker. "It should not be a third-party analysis platform that did evil. It feels similar to the previous case, where Sentry was used incorrectly to collect super-sensitive information that should not be collected."
