Hacking by US from Brazil Goes Corporate

A new pattern has emerged in hacking that requires great firepower and little skill. The ammunition required is a /22 of IP addresses acquired from vendors who specialize in exactly this item. Here is an example of a pattern that is active right now. I could show you a video of the fast scrolling attacks in my log from a set of these addresses, ostensibly from Brazil, but the store where I shopped said they could make me look like I was coming from anywhere I chose. Further study with timing and triangulation is required in order to get an idea of where the source is.

Brazil is a confusing choice of apparent venue, because this could be US soldiers staging an operation against Venezuela: and this is is how they have behaved online since the Gulf War of 1991. I watched them, and still have some printed evidence of the malice they dish out from those military laptops. But let's continue with examples:
