A “secretive” Pakistani software company is receiving millions of dollars by running a massive global scam of selling fake academic degrees using authentication certificates bearing the signature of U.S. Secretary of State John Kerry, a media report said on Monday.

Karachi-based Axact employs over 2,000 people and calls itself “Pakistan’s largest software exporter, with Silicon Valley-style employee perks like a swimming pool and yacht,” The New York Times report said.

The report said Axact portrays a vast education empire including hundreds of universities with “elegant names and smiling professors at sun-dappled American campuses”. The websites offer online degrees in dozens of disciplines and show endorsements, video testimonials, and authentication certificates bearing the signature of John Kerry.

The company allegedly impersonates American government officials who “wheedle or bully” customers into buying State Department authentication certificates signed by Mr. Kerry. “Yet on closer examination, this picture shimmers like a mirage. The news reports are fabricated. The professors are paid actors. The university campuses exist only as stock photos on computer servers. The degrees have no true accreditation,” the NYT report added.

The report cited former insiders, company records and a detailed analysis of its websites and said Axact’s main business has been to “selling fake academic degrees and turn it into an Internet-era scheme on a global scale”.
