Kaspersky has some damning claims against HDD giants Seagate and Western Digital, where it has said that the NSA has spying backdoors installed onto the HDD firmware of the leading HDD manufacturers products.
The cyber-security giant says that the US spy agency has full access to raw data, agnostic of partition method (low-level format), file system (high-level format), operating system, or even at the user access level. Kaspersky has said that it has found PCs in at least 30 countries with the spying programs installed, with the most infections found in Iran. After that, we have Russia, Pakistan, Afghanistan, China, Mali, Syria, Yemen and Algeria.
Kaspersky has said that the HDD firmware backdoors are used right now to spy on foreign governments, telecommunication giants, banks, nuclear researchers, the media, and many more. Kaspersky isn't outright naming the company that has designed the malware, but it has said that the company responsible has close ties with the development of Stuxnet. But it does get worse, as the company adds that each time you turn your PC on, the malware is activated, which means it has utter control to all of the critical OS components - possibly gaining access to your network, and file system.
