The FBI has issued a warning regarding the use of hacked police emails to file fraudulent subpoenas. The agency has revealed that cybercriminals have exploited compromised email accounts belonging to law enforcement officials to create and send counterfeit legal documents. The FBI emphasizes that these fake subpoenas are designed to deceive and intimidate individuals or organizations into complying with false demands. This tactic highlights the growing trend of cybercriminals employing social engineering techniques to manipulate victims into divulging sensitive information or taking actions that benefit the attackers. The FBI advises individuals and businesses to remain vigilant and exercise caution when receiving any official-looking communication, particularly legal documents, by verifying their legitimacy through official channels.
