Microsoft Makes Phishing Easier (What Users Should Know)
Contents
Not every security failure is sophisticated.
Some of the most dangerous risks are low-tech, silent, and visually subtle. This is one of them.
When a platform presents information to a user, it carries a responsibility: show the truth clearly. Not attractively. Not stylishly. Truthfully.

Microsoft Should Change Its Default Font. Users Should Too.
If a design choice prioritizes aesthetic typography over legibility in security-critical contexts, it becomes part of the threat model. A system that accidentally tricks its own users for the sake of “beautiful type” is no longer neutral. It is aiding deception.
Microsoft sits at the center of global trust. That trust includes an obligation to ensure its interfaces do not distort reality; especially when identity, authentication, and digital safety are involved.
This is not a theoretical risk. It is an active attack vector.
Email phishing detection that relies on typos and grammar is no longer valid now that AI has made crafting these much easier for most languages. Modern campaigns exploit trust.
The font becomes part of the attack surface. When typography blurs character boundaries, it undermines the one control users are told to trust: the domain name.
If Microsoft corrected kerning and character spacing, this entire class of attack would collapse instantly.
No malware required. No exploit chain. Just typography discipline.
Design Failures Undermine Security And Trust
If Microsoft were to correct the kerning and character spacing in its default system fonts, a whole category of visual phishing attacks would be eliminated immediately.
This fix would require no malware, no complex exploit chains; just attentive and disciplined typography choices.

The True Cause: Design, Not User Behavior
Security training often instructs users to scrutinize sender domains. While users follow this advice, their trust is betrayed by the interface itself when it visually misleads them.
The core issue is not a lack of user education, but a failure in the way content is rendered.
Secure systems should not depend on users performing painstaking visual checks to ensure their safety; instead, they should guarantee clarity by default.
Why Changing The Default Font Is A Security Measure
- It ensures clear distinctions between easily confused character pairs such as “rn,” “cl,” “vv,” and “il.”
- It disrupts impersonation tactics that rely on these optical similarities to deceive users.
- It reduces the success rate of phishing attacks at the earliest stage of user interaction.
- It enhances phishing resistance without requiring any change in user behavior.
This approach represents a low-cost, high-impact form of security engineering.

Immediate Actions For Users
Relying on Microsoft to address this issue is not practical in the short term. Users can protect themselves now by choosing fonts that offer unmistakable separation between characters. Recommended options include Consolas, Courier New, Fira Code, and JetBrains Mono. These fonts make spoofed domains stand out, empowering users to accurately verify identities.
The Broader Security Implications Of Typography
Typography is not merely an aesthetic concern—it is a foundational aspect of system security. It is inconsistent for Microsoft to invest heavily in fixing technical vulnerabilities while allowing a visual exploit to remain present in everyday interfaces.
Security must be addressed at its source, and typography is one such origin point.
Conclusion
If Microsoft were to improve kerning and character distinction in its default fonts, this specific phishing technique would not just be weakened—it would be eliminated. Until that happens, the standard Windows font will continue to facilitate social engineering attacks.
Changing the font is not simply a matter of personal preference; it is a vital step in maintaining digital hygiene, and it is long overdue.
