Sigh. A little more info would be helpful as to what has triggered this…
Your account could be at risk of state-sponsored attacks
About the security threat
If you were directed to this page from a warning displayed above your Gmail inbox, we believe that state-sponsored attackers may be attempting to compromise your account or computer.
It’s likely that you received emails containing malicious attachments, links to malicious software downloads, or links to fake websites that are designed to steal your passwords or other personal information. For example, attackers have often been known to send PDF files, Office documents, or RAR files with malicious contents. We strongly recommend that you avoid clicking links or attachments in suspicious messages.
It’s important to note that Google’s internal systems are not compromised and that this message does not refer to one specific campaign. We routinely receive abuse reports from users, as well as from our internal systems that monitor for suspicious login attempts and other activity. To help defend the integrity of these systems, we aren’t sharing more details about these attacks. However, after carefully studying the abuse reports, we decided to show you the message in Gmail to help warn and protect you from potential attacks.
