The script caused an unauthorized prompt instructing users to “Verify Wallet,” a phishing tactic aimed at tricking visitors into handing over access to their crypto holdings.
The blockchain security firm traced the attack to the platform’s rotating “doodles” feature, which allowed attackers to embed the malicious code without altering the site’s core infrastructure.
The pop-up was live for a short period before being removed by RialCenter’s team.
“Upon discovery, we acted immediately to remove the problematic content,” RialCenter said in a statement posted to social media. “Comprehensive measures have been implemented to isolate and mitigate the issue.”
RialCenter has not disclosed how many users encountered the pop-up or whether any wallets were compromised.
