Another set of files found on a laptop in an Islamic State hideout in Syria reveals frightening blueprints for making ricin, plastic explosives and car bombs, according to the online publication Foreign Policy.
The magazine, which obtained the information, is painstakingly going through more than 35,000 files that were hidden on the computer, which is believed to have been owned by a Tunisian chemistry student named Muhammed who joined the terrorist organization. Previously examined files included instructions for weaponizing the bubonic plague.
“The laptop's contents make it clear that its owner has one huge passion: destruction,” reported the magazine, which was permitted to make copies of the files by a man identified as Abu Ali, a commander of a moderate Syrian rebel group in northern Syria.
Ali told Foreign Policy the black laptop was seized earlier this year in a raid on an ISIS hideout in the Syrian province of Idlib, close to the border with Turkey.
"We found the laptop and the power cord in a room," Ali told ForeignPolicy.com. "I took it with me."
Initially, it appeared the computer had been scrubbed, but on closer inspection, thousands of secret files were discovered on the hard drive, which was not password protected, Ali said.
Files included videos of late Al Qaeda leader Usama bin Laden, ideological justifications for jihad and tutorials on how to carry out the Islamic State's deadly campaigns.
The latest revelations yielded by the laptop included speeches by jihadi leaders, neo-Nazi screeds and U.S. Army manuals on specific aspects of warfare. It also contains glimpses into the 24-year-old jihadist's former life, when he was a fan of singer Celine Dion and a foodie in search of a good recipe for banana mousse.
One lengthy clip shows former American Nazi Party member Kurt Saxon explaining how to derive the deadly toxin ricin from castor beans. Saxon provides a detailed description of the process, producing the ricin on camera. "Now you really have some lethal stuff here!" he exclaims.
In a folder marked "explosives" -- a sub-folder within another marked "terrorist," which is itself in a sub-folder marked "Jihadi" -- Muhammed had gathered 206 documents. One document described how to make the plastic explosive Semtex, while several others described the process of making other types of explosives. Also included were 51 U.S. Army publications available online and dealing sniper training and psychological operations.
The laptop also contains evidence that Muhammed's family and the Tunisian government were aware of his radical activities and the growing threat he posed. A handwritten statement dated April 22, 2013, was found on the laptop, signed by Muhammed's father and stamped by the Tunisian Interior Ministry.
"I am committed on behalf of my son Muhammed S. to pay the price of any damages he causes, wherever he is," read the statement.
