Another day goes by, another hacking claim is made, but this one just as daunting as the previous one put out by Bloomberg against Supermicro. The publication has reported that the network cards on-board of Supermicro motherboards were compromised and sent to “[a] major US Telecom” company that subsequently removed the affected devices in August. However, the report provides little else in terms of details. If true, this should be terrifying to any security professional. If false, heads could very well roll.

Initially, the claim was made by Yossi Appleboum, the co-chief executive officer from Sepio Systems in Gaithersburg, Maryland. His background in Israeli intelligence gives him some credibility, however, the claim he is making is up against some rather strongly-worded backlash from nearly everyone in the telecom industry.
