Malicious Content

QR codes can be designed to link to websites or applications containing malware, phishing attempts, or other harmful content. Scanning a malicious QR code could result in your device being infected with malware, leading to data breaches, financial loss, or identity theft.

Data Leakage

Some QR code scanning apps may request unnecessary permissions or access to your device's camera, contacts, or other sensitive data. This could potentially lead to data leakage or unauthorised access to your personal information.

Accessibility Issues

QR codes may not be accessible to individuals with certain disabilities, such as those who are visually impaired and rely on screen readers. Relying solely on QR codes for essential information could exclude these individuals from accessing it.

Physical Security Risks

QR codes can be placed in physical locations where they may lead users to dangerous or compromised websites. For instance, an attacker could place a malicious QR code on a poster in a public place, leading unsuspecting individuals to phishing websites or sites containing explicit or harmful content.

Social Engineering Attacks

QR codes can be used in social engineering attacks to trick users into performing actions they wouldn't normally do, such as entering sensitive information or downloading malicious apps. For example, a QR code could lead to a fake login page designed to steal your credentials.

False Advertising

QR codes on advertisements or product packaging may lead to misleading or fraudulent websites or promotions. Scanning such QR codes could result in wasted time, money, or exposure to scams.

Data Privacy Concerns

Scanning QR codes may expose your personal information, such as your location, browsing history, or device information, depending on the content linked to the code. This information could be used for targeted advertising, surveillance, or other privacy violations.
