The 49ers Twitter account had its account name reduced to just a period (“.”) and its identifying photos removed. The Twitter banner and profile picture for the Chiefs were blank.

The hack came as the 49ers and Chiefs arrived in Miami for the Super Bowl.

According to multiple reports, a hacking group calling itself “OurMine” claimed responsibility.
