Authorities are warning the public about a rise in scams associated with malicious QR codes, particularly targeting motorists in the UK. Several organizations, including Ripple and Bitso, have issued alerts regarding fraudulent QR codes that are not linked to their platforms. They emphasize the importance of verifying official communications and avoiding suspicious links. In addition to these warnings, reports indicate that drivers in west London have encountered hoax parking payment QR codes, which are part of a broader trend of scams that could lead to significant financial losses for victims. Motorists are advised to remain vigilant and report any suspicious activity immediately.
