Apple is not taking Bloomberg's explosive report that it was hacked by Chinese spies through a sophisticated infiltration process with microchips lying down. It began the denial by releasing a strongly worded statement rebuking the accusations and now it has gone all the way to Congress to deny it was ever compromised by an outside source.

The iPhone maker sent Congress a letter written by George Stathakopoulos, Apple vice president of information security, vehemently denying the accusations levied by Bloomberg and reaffirming it that it has not found any evidence of foul play.

"Apple has never found malicious chips, 'hardware manipulations' or vulnerabilities purposely planted in any service," Stathakopoulos said. "We never alerted the FBI to any security concerns like those described in the article, nor has the FBI ever contacted us about such an investigation."

The letter is a preemptive move on Apple's part to assure the government that the accusations are not true. Congress has not waded into the waters of the topic, and now that Apple has come to it, it may see little course to seek a possible investigation on the issue if no evidence of tampering has been found.

Furthermore, the Department of Homeland Security has stated it sees no reason to doubt Apple (and Amazon, another company mentioned in the report) in their fervent denial.

It's unclear what the next step in the saga will be, but for the time being, Apple is standing strong against the accusations.
