  • Binance had not initially confirmed a hack, and the FEC outage was not confirmed as a cyberattack.whatgotpwned.com au.pcmag.com The university health center incident is not sufficiently identified or supported by the available sources.

Claims reviewed

  • The Polymarket and Binance incidents are well-documented, but the FEC incident occurred earlier in the week than the Polymarket/Binance incidents.
