The National Security Agency has issued guidance recommending that residents of Maine, New Hampshire, and Massachusetts regularly power down their mobile phones as a cybersecurity measure. The advisory, released in January 2024, suggests weekly phone reboots as part of a comprehensive strategy to protect devices from malware and spyware infiltration, following similar recommendations in recent CISA guidelines on mobile security.
According to the NSA’s guidance, regular device reboots can effectively disrupt malicious software connections, particularly “zero-click exploits” that can be installed without user interaction or awareness. The agency recommends performing these reboots at least once per week. The recommendation comes amid growing concerns about sophisticated surveillance tools like the NSO Group’s Pegasus spyware, which has been documented by privacy advocates as a significant threat to mobile device security.
The advisory outlines several additional protective measures for mobile device security. These include disabling Bluetooth connectivity when not in use, turning off location services during periods of non-necessity, avoiding public charging stations, and implementing secure passcodes containing a minimum of six digits. The measures complement recent initiatives by federal agencies to strengthen mobile authentication, including the promotion of phishing-resistant authentication methods.
Investigative journalist Ronan Farrow, speaking on the Daily Show, corroborated the effectiveness of regular reboots. “Contemporary spyware variants are typically neutralized by this simple procedure,” said Farrow. He indicated that device restarts can provide protection against various forms of malware and unauthorized data collection, a particular concern given recent incidents of sophisticated phone scams in Massachusetts.
The guidance emerges amid increasing focus on mobile device security. Mobile phones now serve as essential tools for communications, financial transactions, photography, and media consumption, making their security increasingly critical. The advisory represents part of ongoing efforts to address evolving cybersecurity challenges in mobile computing, particularly as government agencies and financial institutions implement stronger authentication requirements and security protocols for mobile services.
