Phishing attacks using malicious QR codes surged fivefold from Aug to Nov 2025, tricking users via fake emails and PDFs to steal credentials.
Kaspersky reported a fivefold surge in phishing attacks using malicious QR codes from August to November 2025, with detections rising from 46,969 to 249,723.
Cybercriminals are embedding these codes in fake emails and PDFs, posing as routine messages like HR notices or invoices, to steal credentials via mobile devices.
The attacks bypass traditional email security, often combined with vishing, and exploit the ease of scanning QR codes.
Kaspersky warns organizations remain vulnerable without advanced detection tools and user training, urging improved security measures to prevent data breaches and financial loss.
