The cyber-security company Crowdstrike claimed that the "Russia" hacked the Democratic National Committee. It also claimed that "Russia" hacked artillery units of the Ukrainian army. The second claim has now be found to be completely baseless. That same is probably the case with its claims related to the DNC.Much of this has already been posted here previously, but b pulls it together. Moreover, it is relevant now owing to the recent testimony of FBI chief James Comey that the agency never actually investigated the alleged DNC "hack" forensically and there is good reason to think that it was actually a leak rather than a hack.
There are some good comments, too.
Internet security is highly important, of course, but without oversight it can lead to government management of the national and global information systems.
In this case Congress seems to be bent on a witch hunt rather than a real investigation.
