The Federal Revenue Service of Brazil has issued a warning about a new scam where fraudsters are sending fake emails and SMS messages to taxpayers. These communications appear to be official notifications from the tax authority, alerting recipients to supposed fiscal irregularities and directing them to click on provided links to access a 'guide for resolving discrepancies.' The emails are signed by a 'Regional Director' of the Federal Revenue Service, adding to their deceptive appearance. The scam utilizes 'spoofing' to mask the real email source, making it appear as if it comes from a legitimate address. In São Paulo, legitimate email addresses of the Federal Revenue Service have been used as a front in these deceptive messages. In the United States, the Federal Reserve has cautioned the public about scammers impersonating its officials. These scammers call individuals, claiming their bank accounts have been hacked and request personal information to 'confirm identity.' The Federal Reserve emphasizes that it will never contact the public via unsolicited calls or emails requesting personal or financial information. The FBI has also issued a warning about scammers posing as employees of its Internet Crime Complaint Center (IC3). These fraudsters contact victims of previous scams, claiming they can help recover lost funds. They use various methods, including social media and online forums, to reach out, and have been known to create personas like 'Jaime Quin,' who they claim is the 'Chief Director' of IC3. The FBI received over 100 reports of such IC3 impersonation scams between December 2023 and February 2025. The FBI advises that its employees will never directly contact individuals via phone, email, social media, or public forums, and will never ask for payment to recover lost funds. Scammers often use 'phishing' techniques and may attempt to install 'malware' on victims' devices through these scams. They also use the messaging app 'Telegram' to further deceive victims. Local law enforcement agencies, including the Hutchinson Police Department in Kansas, have reported similar scams where fraudsters impersonate officers to deceive residents. These scams often involve fake calls claiming to be from specific officers, urging victims to take immediate action.
