Mobile Malware Risks Escalate for Travelers and Remote Workers, Experts Warn
As more individuals embrace remote work and travel, cybersecurity experts are sounding the alarm about the escalating risks associated with unsecured networks and mobile devices.The Transportation Security Administration (TSA) has previously cautioned travelers about these dangers, and recent analysis from companies like Venn, Zimperium, and SlashNext highlights the growing threat landscape.
These risks are not confined to airports; hotels, ride-sharing hubs, and cafes are identified as prime targets for attackers. While the threat is more pronounced overseas, major U.S. cities such as Los Angeles, New York, Portland, Miami, and Seattle are experiencing a surge in mobile malware activity.
David Matalon of Venn emphasizes that these vulnerabilities extend beyond mobile phones to personal laptops used by remote workers. The increasing reliance on unsecured networks for both work and personal activities creates important security gaps. Zimperium points out that compromised devices can serve as entry points into corporate networks,particularly when security controls are lax or visibility is limited.
J Stephen Kowski of SlashNext concurs, stating that mobile devices are a primary target, especially when connected to unsecured Wi-Fi or when users download applications from unofficial sources.He stresses the importance of security teams closely monitoring all mobile endpoints and implementing strict controls to prevent risky connections and app downloads.
The conventional network perimeter has dissolved, according to venn, necessitating a strategic shift for organizations supporting Bring-Your-Own-device (BYOD) policies. The focus must move from securing the device itself to securing the work being performed on it. Venn highlights that current technology allows for the isolation and protection of work-related data and applications, even on personal devices connected to compromised networks. the proactive approach should be to plan for the unavoidable exposure of work data on personal devices rather than questioning if it will happen.
Zimperium advises users to configure their smartphone settings to block connections to public, unsecured Wi-Fi networks. The company notes that over 5 million public unsecured global Wi-Fi networks have been identified since the beginning of 2025, with a significant portion of users (33%) connecting to these vulnerable networks.
