Verizon Mobile Security Index: In the AI Era, the Human Element Remains the Weak Link
Summary Bullets:
- To protect an expansive mobile environment attack surface in the face of a very dangerous threat environment, organizations are ramping up their security investments, with 75% of the 762 polled in a recent Verizon study reporting they had increased spending this year.
- But concerns still loom large threat actors using AI and other technologies and tactics to breach the enterprise; and only 17% have implemented security controls to stave off AI-driven attacks.
Mobile and IoT devices play an essential role in most organizationsβ operations today. However, the convenience and flexibility they bring comes with risk, opening new points of exposure to enterprise assets. Organizations that were quick to embrace bring your own device (BYOD) strategies often didnβt have a solid plan for safeguarding this environment when so many of these devices were under-secured. Enterprises have made progress in layering their defenses to better protect mobile and IoT environments, but there is still room for progress.
In Verizonβs eighth annual Mobile Security Index report, 77% of the people surveyed said deepfake attacks that tap AI-generated voice and video content to impersonate staff or executives, and SMS text phishing campaigns are likely to accomplish their objective. Approximately 38% think AI will make ransomware even more effective.
Despite the increase in cybersecurity spending in most organizations, only 12% have deployed security controls to safeguard their enterprise from deepfake-enhanced voice phishing. Just 16% have implemented protections against zero-day exploits.
Enterprise employees are welcoming AI-driven apps to their mobile devices β with 93% using GenAI as part of their workday routine. They raised red flags, with 64% calling data compromise via GenAI their number one mobile risk. Of 80% of enterprises that ran employee smishing tests, 39% fell for the scam.
AI aside, user error is the most frequently noted contributor to breaches in general, followed by application threats and network threats. Some 80% said they had documented mobile phishing attempts aimed at staff.
While prioritizing cybersecurity spending is important, organizations need to look at whether they are allocating this investment on the right areas. Just 45% said their organization provides comprehensive education on the potential risks mobile AI tools bring. Only half have formal policies regarding GenAI use on mobile devices, and 27% said they arenβt strictly enforced.
