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.

The result is that QR code phishing bypasses many controls that effectively catch text-based phishing.","inLanguage":"hu"},"inLanguage":"hu"},{"@type":"Question","@id":"https:\/\/pageloot.com\/blog\/qr-code-phishing-business-risks-and-fixes\/#faq-question-68f0add58204","position":2,"url":"https:\/\/pageloot.com\/blog\/qr-code-phishing-business-risks-and-fixes\/#faq-question-68f0add58204","name":"Hogyan v\u00e9dhetik meg magukat a kisv\u00e1llalkoz\u00e1sok, ha korl\u00e1tozott biztons\u00e1gi k\u00f6lts\u00e9gvet\u00e9ssel rendelkeznek?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"Focus on the highest-impact controls first: enable multi-factor authentication on all accounts, train employees to treat unexpected QR codes as suspicious and verify through independent channels, and switch any published QR codes from static to dynamic so you can update or disable them if a problem is detected. These steps cost little and eliminate the most common attack paths. Use a QR code scanner with URL preview capability before scanning unknown codes, and establish a clear process for employees to report suspicious codes to IT.","inLanguage":"hu"},"inLanguage":"hu"},{"@type":"Question","@id":"https:\/\/pageloot.com\/blog\/qr-code-phishing-business-risks-and-fixes\/#faq-question-0d855702ce5e","position":3,"url":"https:\/\/pageloot.com\/blog\/qr-code-phishing-business-risks-and-fixes\/#faq-question-0d855702ce5e","name":"Mi\u00e9rt biztons\u00e1gosabbak a dinamikus QR-k\u00f3dok a v\u00e1llalkoz\u00e1sok sz\u00e1m\u00e1ra, mint a statikusak?","answerCount":1,"acceptedAnswer":{"@type":"Answer","text":"Static QR codes permanently encode a destination URL. 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. That combination of flexibility and visibility makes dynamic codes significantly safer for any QR code used in public-facing or ongoing business contexts.","inLanguage":"hu"},"inLanguage":"hu"}]}},"_links":{"self":[{"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/posts\/37652","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/comments?post=37652"}],"version-history":[{"count":15,"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/posts\/37652\/revisions"}],"predecessor-version":[{"id":54977,"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/posts\/37652\/revisions\/54977"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/media\/54101"}],"wp:attachment":[{"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/media?parent=37652"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/categories?post=37652"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pageloot.com\/hu\/wp-json\/wp\/v2\/tags?post=37652"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
