Beware: Device Code Phishing Scams Targeting Financial Firms
Have you felt secure in your cyber defence strategy only to encounter a new threat? Presenting a looming scam targeting businesses, including those in the wealth management and chartered accountancy sectors. This latest scam doesn’t even require your password.
Understanding Device Code Phishing
Enter device code phishing, an emerging threat drawing attention from security experts, including Microsoft. Unlike typical phishing scams, where credentials are mined, this attack style involves duping users into willingly providing access to their accounts. It sidesteps traditional defences by exploiting legitimate Microsoft login interfaces, aligning them perfectly with the operational realities of financial firms.
How Device Code Phishing Operates
This scam often begins with an email masquerading as a trustworthy source, such as HR or a company executive, perhaps even related to a Microsoft Teams meeting involving a client data review. It directs users to valid Microsoft login pages, prompting them to enter a “device code” included in the email to complete or join the meeting.
Here’s the twist: inputting the code grants the scammer access to your Microsoft account. They effectively bypass multi-factor authentication since the login proceeds through standard pathways. Once inside, they can scrutinise sensitive emails, access confidential client files, and use your account to commit further breaches within the firm.
Why Is This So Concerning?
The dangerous aspect lies in its subtlety; the real Microsoft interface replaces the typical phishing red flags, like unfamiliar links or manipulated password forms. Even formidable security solutions might overlook such tactics, seeing them as legitimate actions.
Once access occurs, perpetrators may exploit session tokens, the digital “keys” to ongoing sessions, evading interventions like password resets. This raises significant compliance concerns, especially with frameworks from bodies like ICO and FCA, which mandate stringent client data protection.
Steps to Thwart Device Code Phishing
Implement Critical Precautions
Your team must exercise increased vigilance regarding login requests. Scrutinise communications involving unfamiliar code requests. Encourage verifying the legitimacy of such emails directly with colleagues, using distinct channels such as calls or messaging apps.
Be aware that no authentic Microsoft procedure involves entering another’s provided code. Reports that challenge this norm warrant immediate scrutiny.

Develop Robust IT Protocols
Consider consulting with your IT team or managed IT provider to assess the necessity of device code logins, particularly if it isn’t integral to your daily operations. Deactivating this feature enhances security. Furthermore, enforce policies that permit logins strictly from trusted devices or locations. Explore insights from the National Cyber Security Centre to stay ahead in safeguarding practices.
Foster a Culture of Cyber Awareness
Success hinges on building awareness. Commit to regular cybersecurity training, making security a concrete part of the company culture. Educate your employees on identifying threats and capitalising on their ability to spot and report anomalies.
