Authorities and legal experts in Paraguay, Spain, and the Czech Republic have issued warnings ~~and guidance~~ regarding a rise in banking fraud and phishing attacks. In Paraguay and Spain, officials noted that increased electronic transactions have led to a parallel rise in scams involving fake messages, phone calls, and online channels used to steal personal and financial data. Recommendations for prevention include using two-factor authentication, avoiding suspicious links, and verifying all communications directly through official bank channels. In the Czech Republic, legal guidance for victims of phishing SMS scams emphasizes the importance of filing criminal complaints with the police. Experts noted that while victims may claim damages through court if a perpetrator is identified, banks frequently refuse to reimburse losses if they determine the client did not exercise sufficient caution according to their terms and conditions. Recent alerts from Spanish law enforcement, including the Mossos d'Esquadra and the Policía Nacional, highlight a sophisticated surge in ‘smishing’ (SMS-based fraud). Criminals are ~~now~~ sending fraudulent texts that can appear within the same message thread as legitimate bank notifications, making them difficult to distinguish. These messages often use false warnings of unauthorized charges to create a sense of urgency. Scammers then pose as bank employees to trick victims into providing verification codes, which are actually used to authorize fraudulent transfers rather than cancel them. The sophistication of these attacks has increased, with criminals using short numbers that imitate official ones and domains that closely resemble those of legitimate financial institutions.
