A recent phishing campaign imitating the U.S. Postal Service is targeting mobile devices through deceptive PDF files. These PDFs utilize a sophisticated hiding method for clickable links to evade detection by security systems. Researchers from Zimperium uncovered over 20 malicious PDFs and 630 phishing pages, indicating a large-scale operation that could impact businesses worldwide. Users are tricked into providing sensitive information like payment details, which cybercriminals then encrypt and harvest, raising concerns about security and the increasing vulnerability of mobile platforms.
