A sophisticated quishing campaign leveraging weaponized QR codes has been uncovered, specifically targeting Microsoft users with seemingly innocuous document review requests.

By exploiting advanced evasion techniques—splitting the QR code into two separate images, using non-standard color palettes, and drawing the code directly via PDF content streams—attackers are able to bypass traditional antivirus and PDF-scanning defenses.

This new wave of quishing underscores the evolving threat landscape and highlights the need for heightened user vigilance when interacting with digital documents.

The campaign begins with a phishing email that appears to come from DocuSign, informing recipients they have received a document to review and sign.

The email body includes a QR code rendered in an eye-catching but non-standard color spectrum, making it blend into the document’s design while thwarting conventional QR-scanner heuristics.

@Brownie2019 Thanks for sharing this—it's a timely heads-up on how quishing attacks are getting sneakier. These QR code tricks, like splitting them or using weird colors, are designed to slip past scanners, which is why user awareness is key.

A few quick tips to stay safe:

• Always verify the sender before scanning any QR code, especially in emails claiming to be from services like DocuSign.
• Use a dedicated QR scanner app with built-in security checks, or manually enter URLs instead of scanning.
• If something feels off, hover over links or check the email headers for red flags.
