The U.S. Navy has issued an unclassified memo warning sailors to tighten social media security amid heightened cyber threats from Iran-linked actors during the ongoing conflict. The advisory, released on April 17, highlights social engineering campaigns targeting Department of the Navy personnel and their families through phishing, messaging apps, and dating platforms. Sailors were instructed to remove personal information from online profiles, enable two-factor authentication, and avoid public Wi-Fi to mitigate risks.
Navy Secretary John Phelan emphasized that adversaries are using psychological operations and malicious links to exploit service members. The memo advises sailors to limit posts, research unfamiliar contacts, and disable location tracking on apps. The warning follows reports of Iran-linked hackers targeting U.S. companies, including attempts to breach healthcare and energy sectors.
The Navy’s directive aligns with broader Pentagon policies restricting service members’ online activity but expands on existing guidelines by urging personal device security measures. The advisory comes as diplomatic efforts between the U.S. and Iran appear to falter, with cyber threats escalating alongside the conflict. Experts note that both sides are leveraging digital tools to disrupt operations and influence public perception.
