FBI Warns AI-Generated Voices Used to Impersonate Senior U.S. Officials in Cyber Campaign

/in /tarafından

The FBI has issued a public warning that malicious actors are leveraging AI-generated voice messages and text to impersonate senior U.S. government officials, targeting both current and former federal and state officials in a sophisticated social engineering campaign.

According to the FBI’s announcement on Thursday, the aim of the scheme is to:

  • Gain access to personal accounts of government officials

  • Target additional contacts once access is gained

  • Harvest sensitive information or even solicit funds fraudulently

How the Scheme Works:

  • Attackers initiate text message conversations to build rapport with the targets.

  • Once trust is established, they urge the recipient to switch to another platform, often linking to a hacker-controlled website designed to harvest credentials like usernames and passwords.

  • In some cases, attackers use AI-generated voice clips to convincingly impersonate the tone and mannerisms of known officials.

Threat Scope:

The FBI has not disclosed how many individuals have been targeted or whether the actors are financially motivated cybercriminals or state-aligned entities. The use of generative AI makes attribution and detection more difficult, and the agency continues to assess the full scope of the threat.

This follows a December 2024 warning from the FBI regarding the broader use of AI-generated content — including text, audio, images, and video — to commit crimes such as fraud, extortion, and identity theft.

Broader Implications:

The campaign underscores the growing threat of generative AI in cybercrime, particularly in impersonation and phishing-style attacks aimed at high-value targets. Government agencies and private sector organizations are now being urged to:

  • Strengthen multi-factor authentication

  • Train personnel to recognize AI-driven impersonation attempts

  • Avoid clicking on unsolicited links or moving conversations to unknown platforms

As AI tools become more accessible, security experts warn that digital impersonation will become an increasingly common tactic for attackers seeking access to sensitive systems or socially engineered pathways into secure environments.

Costa Rica’s Presidential YouTube Account Restores Control After Cyber Attack

/in /tarafından

The official YouTube account of Costa Rican President Rodrigo Chaves was restored to government control late on Friday after a cyber attack that had disrupted the account for several hours.

In a statement, the presidency confirmed that experts from the president’s office, the Ministry of Science and Technology, and Google worked together to resolve the breach. While the details of the attacker or group responsible remain unclear, the government assured that no sensitive information had been compromised during the incident.

During the attack, the YouTube profile was altered to display a logo with the word “Strategy” followed by a bitcoin symbol. The most recent videos featured content related to cryptocurrency, which the presidential office confirmed did not originate from them.
