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.

QR code phishing conceals the destination entirely \u2013 the malicious URL is encoded inside the image, invisible until after scanning. This also makes it harder for email security filters to detect, since they see an image rather than a link. The result is that QR code phishing bypasses many controls that effectively catch text-based phishing.","inLanguage":"vi"},"inLanguage":"vi"},{"@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":"L\u00e0m th\u1ebf n\u00e0o c\u00e1c doanh nghi\u1ec7p nh\u1ecf c\u00f3 th\u1ec3 t\u1ef1 b\u1ea3o v\u1ec7 m\u00ecnh n\u1ebfu h\u1ecd c\u00f3 ng\u00e2n s\u00e1ch b\u1ea3o m\u1eadt h\u1ea1n ch\u1ebf?","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":"vi"},"inLanguage":"vi"},{"@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":"T\u1ea1i sao m\u00e3 QR \u0111\u1ed9ng an to\u00e0n h\u01a1n cho doanh nghi\u1ec7p so v\u1edbi m\u00e3 t\u0129nh?","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":"vi"},"inLanguage":"vi"}]}},"_links":{"self":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/37652","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/users\/17"}],"replies":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/comments?post=37652"}],"version-history":[{"count":15,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/37652\/revisions"}],"predecessor-version":[{"id":54977,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/posts\/37652\/revisions\/54977"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media\/54101"}],"wp:attachment":[{"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/media?parent=37652"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/categories?post=37652"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/pageloot.com\/vi\/wp-json\/wp\/v2\/tags?post=37652"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
