The U.S. Federal Bureau of Investigation (FBI) has launched an investigation into an individual who impersonated Susie Wiles, the chief of staff to Donald Trump. The imposter contacted high-profile Republicans via text messages and phone calls made to their private numbers. In one message, the impersonator requested a list of individuals to pardon — a request that was initially believed to be genuine. In another instance, the cybercriminal attempted to solicit a cash transfer. The case underscores how dangerous and sophisticated disinformation has become, particularly with the rise of deepfake technologies and breaches of senior government officials’ mobile devices.
What’s more alarming is that the impersonator’s voice was so convincing that several recipients believed they were actually speaking to Wiles. According to The Wall Street Journal, the fraudster may have used artificial intelligence to replicate her voice. Wiles has since confirmed that her private phone was hacked, although her official government device remained uncompromised. She has urged colleagues to ignore any messages not coming from her verified number.
A Growing Threat to National Security
This incident is part of a larger trend of escalating cyberattacks targeting state institutions. According to the latest data from Check Point Research (CPR), government organizations experienced an average of 2,678 cyberattacks per week in the first quarter of 2025 — a 51% increase compared to the same period last year. Moreover, the government and military sectors were the most exposed to mobile threats across all industries.
Glen Deskin, Head of Engineering at Check Point, emphasized the urgency of adopting a Zero Trust approach to mobile security:
“No device should be trusted by default. Access should depend on identity, device posture, and context. Tools like Mobile Threat Defense (MTD) and AI-powered anomaly detection can stop an attack before data is compromised — but too few institutions are using them. This is no longer just a technology issue — it’s a matter of national security.”
“Signalgate” and Major Communication Failures
This isn’t the only security lapse troubling U.S. officials. In March 2025, the media exposed what has been dubbed “Signalgate” — a scandal in which high-ranking Trump administration officials reportedly discussed sensitive military plans via a group chat on the Signal app. In a major oversight, Jeffrey Goldberg, the editor-in-chief of The Atlantic, was mistakenly added to the group.
The incident led to the demotion of National Security Advisor Mike Waltz and sparked a lawsuit against the administration over possible violations of federal record-keeping regulations.
