There was a bit of FUD on some forums that I was reading today considering the Ring Signature code used by XSPEC. Is the Ring Signature code updated so that it works properly and isn't prone to breaches? Is the dev team working on fixing this problem?
This is old news and have been dealt with on numerous occasions. The math has been fixed a long time ago and is a non-issue. There will be some updates around the anonymous tokens in v1.4.
