Altering the flash chip would be too obvious. It's a textbook 101 supply chain attack... Looking at the flash image (dumping it) or chip (x-raying it) would be the first thing anyone would do if they suspected something fishy. A tiny S

You could be right. But stuffing megabytes of a full copy of the BMC flash image in such a chip may be overkill. You could just as easily man-in-the-middle bytes sent by the legit flash over the SPI DO line...

Except... a key word in the article makes the hack perfectly believable and feasible: "baseboard management controller". If the chip is inserted on the serial data line between the SPI flash memory and the BMC CPU, then, as an ex-

Well this D-Link router shown at CES is "tri-band" (a misnomer, it should be called "tri-channel") so "11 Gbit/s" is just the sum of the maximum data rate achievable in 3 different channels (one channel in

"AC only supports 5gz." That's not an accurate statement. "802.11ac" denotes a set of features, and many of them apply to and benefit the 2.4 GHz band. For example 256QAM encoding boosts the max data rate by 20 or

Good point, but what about the comparison with the old 10-series Titan Xp (released at $1200)? The 20-series improved peak GFLOPS perf by a meager 10%. I still would have expected more from upgrading from 16nm to 12nm. I guess floating poin
