Wiper is a cousin of the notorious Stuxnet virus, which was built by the NSA -- while Alexander was in charge -- in cooperation with Israeli intelligence.
Have the Stuxnet creators actually been proven to be the US and Israel? I thought it was still speculation (but almost certainly true).
There was a lot of circumstantial evidence pointing to this fact already, and Snowden finally confirmed this last year in an interview with Der Spiegel [1].
Ah thanks. I had read about a lot of evidence pointing in the USA's direction, but didn't realize Snowden also confirmed it. Arguably still hearsay, but certainly adds more weight to it.
In addition to the Snowden confirmation, there were some press leaks in 2012 that appear to have confirmed it earlier [1]. Apparently there's still some investigations going on within the U.S. government about who leaked it.
I'd say it's a pretty clear-cut case who was behind Stuxnet.
