A Silent WordPress Breach Could Be the Next Big Crypto Exploit

A critical vulnerability in a popular WordPress plugin can allow hackers to hijack user-facing crypto websites. This vulnerability potentially creates opportunities for malicious actors to inject phishing pages, fake wallet links, and malicious redirects. 

While this flaw doesn’t affect wallet backends or token contracts, it exposes the front-end infrastructure that users rely on to safely interact with crypto services. Although the plugin has since been patched, tens of thousands of sites remain unprotected, running outdated versions. 

A WordPress Plugin’s Scam Potential

Crypto crimes are through the roof right now, and many unexpected vectors can yield new scam attacks. For example, a recent report from Patchstack, a digital security firm, reveals a new WordPress exploit that could potentially enable new crypto scams.

“The plugin Post SMTP, which has over 400,000 installations, is an email delivery plugin. In versions 3.2.0 and below, the plugin is vulnerable to multiple Broken Access Control vulnerabilities in its REST API endpoints…allowing any registered user (including Subscriber-level users who should have no privileges at all) to perform a variety of actions,” it claimed.

These functions included: viewing email count statistics, resending emails, and viewing detailed email logs, including the entire email body.

A WordPress hacker could use this vulnerability to intercept password reset emails, potentially gaining control of administrator accounts.

Many Targets in Crypto

So, how could this WordPress vulnerability lead to crypto scams? Unfortunately, the possibilities are practically endless. Fake customer support emails have been instrumental in many recent phishing attempts, so limited email control is already dangerous.

A compromised site using WordPress could insert fake tokens and scam websites into external links using malicious scripts and redirects.

Hackers could harvest passwords and attempt to use them on a list of exchanges. They could even inject malware into every user who opens a certain page.

Are My Wallets Safe?

On the surface, most crypto wallets and token platforms don’t use WordPress for their core infrastructure. However, it’s often used for user-end functions like homepages and customer support.

If a small or new project without a solid engineering team gets compromised, security breaches could go unnoticed. Infected WordPress accounts could gather user information for future scams or outright direct customers to phishing attempts.

How to Stay Protected

Luckily, Patchstack quickly released a fix for this particular bug. But more than 10% of Post SMTP users, haven’t installed it. That means around 40,000 websites are vulnerable to exploitation, representing a huge security risk.

Savvy crypto users should remain calm and exercise standard security practices. Don’t trust random email links, stick with trusted projects, use hardware wallets, etc. The biggest responsibility is on the site operators themselves.

If a small crypto project runs a WordPress site without downloading Patchstack’s bug fix, hackers could use it to power an endless list of scams. In short, crypto users should be safe as long as they exercise caution with non-mainstream projects.
