Jedna velika kvi\u0161ing kampanja porasla je za 2.400% za samo nekoliko meseci, a analiza operacije usmerene na korporacije pokazala je da je otprilike 29% zlonamernih e-poruka sadr\u017ealo QR kodove.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-where-attackers-plant-malicious-qr-codes\">Gde napada\u010di postavljaju zlonamerne QR kodove<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Napadi putem e-po\u0161te i dokumenata<\/strong> su naj\u010de\u0161\u0107i metod isporuke. Napada\u010di ugra\u0111uju QR kodove unutar PDF ili Word priloga kako bi zaobi\u0161li bezbednosne filtere e-po\u0161te. U 2023. godini, 82% kvi\u0161ing napada imitiralo je pouzdane brendove \u2013 Microsoft je bio meta u 51% zabele\u017eenih slu\u010dajeva, zatim DocuSign sa 31% i Adobe sa 15%. Izme\u0111u sredine 2024. i kraja 2024. godine, istra\u017eiva\u010di su otkrili preko 500.000 fi\u0161ing e-poruka koje su sadr\u017eale QR kodove ugra\u0111ene u PDF-ove.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Fizi\u010dko manipulisanje<\/strong> je jednako opasno.

Uprava za socijalno osiguranje posebno upozorava da legitimni QR kodovi na zvani\u010dnim oznakama obi\u010dno nisu nalepnice; kod primenjen kao nalepnica treba smatrati sumnjivim.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Mamci socijalnog in\u017eenjeringa<\/strong> upotpunjuju sliku. \u017drtve se podsti\u010du da skeniraju QR kod kako bi ostvarile popust, povezale se na besplatan Wi-Fi ili popunile anketu.

Dynamic QR codes route through a short redirect URL that you control centrally. You can change the destination, add password protection, set expiration dates, and monitor scan activity in real time.

If that URL is compromised \u2013 or if an attacker copies your code and redistributes it pointing to a malicious site \u2013 you have no way to correct the original printed code without reprinting everything. Dynamic QR codes route through a short redirect URL that you control centrally. You can change the destination, add password protection, set expiration dates, and monitor scan activity in real time. If something looks wrong, you can disable the code immediately.
