The FBI has issued a public warning about a rising scam involving QR codes placed on packages delivered to people who never ordered them.

According to the agency, these codes can lead recipients to malicious websites or prompt them to install harmful software, potentially exposing sensitive personal and financial data.

The scheme is a variation of the so-called brushing scam, in which online sellers send unordered items and use recipients' names to post fake product reviews. In the new version, QR codes are added to the packaging, increasing the risk of fraud by directing users to deceptive websites.

While not as widespread as other fraud attempts, the FBI urges caution. The agency recommends avoiding QR codes from unknown sources, especially those attached to unrequested deliveries.

It also advised consumers to pay close attention to the web address that appears before tapping on any QR code link.

Authorities have noted broader misuse of QR codes, including cases where criminals place fake codes over legitimate ones in public spaces.

In one recent incident, scammers used QR stickers on parking meters in New York to redirect people to third-party payment pages requesting card details.
