“If your account was locked, this does not necessarily mean we have evidence that the account was compromised or accessed,” the company wrote. “So far, we believe only a small subset of these locked accounts were compromised, but are still investigating and will inform those who were affected.” The company said it had “no evidence that attackers accessed passwords.”

Twitter didn’t say how many accounts were affected by these measures, or provide instructions on how affected users could regain access. “We’re working to help people regain access to their accounts ASAP if they were proactively locked,” Twitter said. “This may take additional time since we’re taking extra steps to confirm that we’re granting access to the rightful owner.”
