Apple has since denied this, US intelligence agencies have also denied this, and just to be safe, Super Micro ordered an outside investigation of its hardware. That investigation has since been complete and according to the findings, it appears that Super Micro’s motherboards have been found to be clear of malicious chips.
The Reuters’ report claims that the investigation was conducted by Nardello & Co who tested various samples of motherboards in current production against those sold to Apple and Amazon, both of whom were named in the original Bloomberg report. They also examined software and design files and found that there were no unauthorized components or signals being sent out.
Apple had previously suggested that the Bloomberg report might have been mixed up over a separate and non-related incident from back in 2016, although the publication has since stated that they are standing by its report, despite calls from Apple’s CEO Tim Cook and Amazon Web Services CEO Andy Jassy to Bloomberg to retract their report.
