A new wave of phishing techniques has been targeting multiple industries. Anyone heard of ‘Quishing’?

Phishing links within emails are not a new problem, with the most common email lures often coming in the form of a request to update bank or payment details, updating personal details, or concerning account security.

These lures are often accompanied with social engineering. Commonly, threat actors threaten fines or account closures, sometimes even law enforcement involvement to encourage victims to engage.

However, a new spin on the phishing campaign has seen in increase just recently – and it’s been given the nickname ‘quishing’ (QR + phishing = quishing).

Threat actors are employing QR codes within their emails or attachments that re-direct users to a spoofed page.

Another method is changing a legitimate QR for a malicious version without the owner’s knowledge, or using a third-party QR scanner app which can also lead to a malicious domain.

In recent weeks, researchers have identified an increase in malicious QR codes being embedded within emails or attachments in lieu of traditional links. The code directs users to a fake, but convincing, webpage, for example a Microsoft page requiring log in credentials. Unlike simple links, these codes are more likely to reach a victim’s inbox as they are more difficult to detect as malicious.

QR codes became increasingly popular during the Covid-19 pandemic, with a huge array of companies using them to interact with their customers – from restaurants replacing physical menus with online versions to medical centres allowing customers to provide feedback of services easily.

The risk for compromise is relatively low if the QR code is received onto a mobile phone as there doesn’t seem to be a way to execute a QR code without physically scanning it. However, if these codes can be scanned from another copy, it’s encouraged to exercise the same caution as would be given to suspicious or unexpected URLs.
