Be careful how you connect.
There's no subject guaranteed to rile cybersecurity experts more than public WiFi security — not even the mythological horrors of juice jacking. Any suggestion users should beware connecting to one of the tens of millions of airport, hotel, mall and coffee shop hotspots will always spawn a tirade of sarcastic posts on social media.
But sometimes the threat is real. Your devices can become 'serious liabilities,' the security team at Zimperium has just warned, 'especially during travel, when vigilance is low, free public-WiFi are everywhere, and attackers know exactly how to strike.'
Let's be very clear. Public WiFi is broadly fine. As long as the network is real, you are using encrypted apps or websites, and you don't download any software or overshare any information with the captive portal that pops up asking you to connect.
The FTC says as much: 'Because of the widespread use of encryption, connecting through a public Wi-Fi network is usually safe.'
But even government advice is divisive on this subject, and TSA has a different message: 'Don't use free public WiFi, especially if you're planning to make any online purchases. Do not ever enter any sensitive info while using unsecure WiFi.'
Zimperium says there have been 'over 5 Million Public Unsecured Global Wi-Fi networks found since beginning of 2025, with 33% of users connecting to public unsecured networks.' And that 'during travel, these risks multiply.'
Its warning is aimed at enterprises whose employees will be taking summer vacations with devices that connect to corporate email and other IT systems. 'Airports, hotels, ride-share hubs, and cafés all offer rich hunting grounds for attackers.'
Public WiFi warning.
Zimperium says 'employees, often multitasking or in a hurry, are far more likely to click, install, or connect without thinking twice.' The researchers list four types of attack that users should beware, even as they continue to connect on the go:
Attacks are especially prevalent overseas, but Zimperium also warns that 'major U.S. cities like Los Angeles, New York, Portland, Miami, and Seattle are seeing increased mobile malware activity—particularly during peak travel months.'
Staying safe is fairly straightforward — follow these five golden rules:
You should also avoid installing apps from outside official stores and ensure your OS is up-to-date with the latest security patches. If you're running one of the billion phones with an OS no longer eligible for these updates, you should go get an upgrade.
'Whether you're heading to Southeast Asia or a European business hub,' Zimperium says, 'mobile malware doesn't discriminate by location—but it thrives on opportunity. And summer travel creates plenty of it.'
