Reading a post about security audit from more than a year ago, which is currently accessible only via Wayback machine I became very suspicious that rug pull by Atomic Developers was pre-programmed.
Specifically, we found that user funds are at increased risk due to the current use and implementation of cryptography. We also noted a lack of adherence to wallet system design and development standards and best practices, reducing the overall security of the system and increasing the Atomic Wallet’s attack surface.
By having lots of various security issues they may deny involvement into attack. The lack of specific use-case for the wallet also leads to conclusion that Atomic Wallet was a giant honeypot.
