Report for Zkcall.net
Why we think so
zkcall.net is a software company based in Tallinn, Estonia, focused on secure collaboration tools with blockchain-based identity verification. The site has low to moderate traffic (~750 visits in November 2025) primarily from the US (78%) and India (22%). It maintains valid SSL certificates and is registered since early 2024. Public reviews or complaints are not available, and no lawsuits have been reported. However, the "zk-call" name is linked to a malicious MacSync Stealer malware campaign disguising as a chat app installer, raising serious security concerns despite no direct scam reports on zkcall.net itself. The company provides contact emails and has an active presence on social media and GitHub. Proceed with caution due to the malware association and limited independent feedback.
