Google’s Threat Analysis Group tracks actors involved in disinformation campaigns, government backed hacking, and financially motivated abuse. We have a long-standing policy to send you a warning if we detect that your account is a target of government-backed phishing or malware attempts. So far in 2021, we’ve sent over 50,000 warnings, a nearly 33% increase from this time in 2020. This spike is largely due to blocking an unusually large campaign from a Russian actor known as APT28 or Fancy Bear.
