I absolutely believe it’s possible that LastPass has been compromised more than they’ve let on and I won’t be surprised if we eventually find out vaults are vulnerable, but I don’t believe this is how it would play out.
Sunday the 18th is conveniently around the time of the latest announcement, but not the time of the actual hack. Feels like someone is over fitting.
I find it implausible that the first hint of vault compromise comes 4 months after the hack and is against a low value cryptocurrency wallet. Especially considering that when LastPass first had issues, there were dozens of people reporting personal experiences of it here on HN — if LastPass vaults are compromised, the internet would be flooded with reports.
Good points.
The time might have been spent analyzing the source code for vulnerabilities in the way the vaults were being protected.
If someone had put the key in the URL field (because there is no corresponding URL because it's not a credential), and the URL field was unencrypted, that could account for it.
