Are QR codes safe?
A malicious URL that contains custom malware can be embedded in a QR code by attackers, which when scanned could exfiltrate data from a mobile device. It is also possible to include a malicious URL in a QR code that takes users to a phishing site where users who aren't paying attention could give out personal or financial information.
An attacker can easily alter a QR code to point to a different resource without being noticed because humans cannot read them. Even though many people are aware that QR codes can open a URL, they may not be aware of the other actions QR codes can start on a user's device. These actions can include writing emails or adding contacts, in addition to opening a website. Security threats to QR codes can be particularly challenging because of this element of surprise.
Placing malicious QR codes in public and sometimes concealing legitimate QR codes is typical of an attack. When users scan the code, they are taken to a malicious website that may contain an exploit kit that compromises a device or a spoofed login page for user credentials. Drive-by downloads are a feature of some websites, so simply going to the site can start a malicious software download.
In general, mobile devices are less secure than computers or laptops. The use of QR codes on mobile devices raises the possibility of risks.

Can someone hack a QR code?
The security risks associated with QR codes come from their destinations rather than the codes themselves, so they cannot be hacked.

Because of this, mobile users should only scan codes that have been sent by a reputable sender.
How do QR codes work?
QR codes' patterns are binary codes that can be decoded to reveal the data contained within.
The three large squares outside a standard QR code can be used by a QR reader to identify it. It knows that everything in the square is a QR code once it has identified these three shapes.
The QR code is then analyzed by the QR reader by being reduced to a grid. It determines a value for each individual grid square based on whether it is black or white. After that, it arranges grid squares into larger patterns.
