Absently, he wondered if anyone had figured out his null cipher message. Please Allah, he thought to himself. Give me a few leaders among my team. He walked over to the stove, lit the name on one of the front burners, and set the water to boil. The name on the stove ignited his memory. His brother's frightened face filled his mind as he thought back to that fateful day at the coffee shop. He wasn't there when it had happened, but he made up for that every night through his own nightmares of the event.
When his parents and he had first arrived at the site, he was sure there had been a mistake. But his father had seen him, his brother.
At first, it was a disembodied hand sticking straight up out of the rubble. He remembered his father and several other men pulling large chunks of rock out of the pile until his brother's ravaged body was found. The wet teapot hissed gently as the water still clinging to the outside of the pot sizzled into steam. He shuddered to himself and pushed the morbid details back into the recesses of his mind. His purpose flooded back into his heart and he reflected on his research today at school. One of the papers he had found was written back in the late s and discussed a concept called stego-noise.
The paper was written by Fabian Hansmann and described a mechanism for writing a benign Internet worm that would search for certain vulnerabilities. When computers were found with the appropriate security vulnerability, they would be compromised, allowing the worm to embed all suitable target files on the drive with steganography.
Over time, these infected yet benign images would clutter the Internet with images, audio files, and other binary files that had useless steganography, making the detection of legitimate steganographic files extremely difficult. Salah knew that even the most advanced algorithms for detecting steganography today had a surprising number of false positives, making them somewhat unreliable.
But this concept could threaten the fragile balance between the creation of steganography and the detection of it. The premise of the paper had described a benign worm written to take advantage of vulnerabilities on computer systems around the world. As the worm located systems with the vulnerabilities it was looking for, it would infect every image on each system it had access to with a benign form of steganography. The worm was programmed to insert random information into each image, creating useless steganography, or stegonoise, within the image.
When law enforcement officials attempted to scan a computer system or the Internet for images with potential hostile or hidden content, eventually they would be inundated with large numbers of images appearing to have steganography within them. When the paper was originally written, the concept was intriguing to hackers, but largely ignored by the general Internet community, including law enforcement and the military. But in today's networked world, where worms are a daily reminder of the insecurity of the Internet, such a worm could actually generate a tremendous amount of stego-noise in a very short period of time.
The Slammer worm was a good indication of how quickly a properly coded worm could spread. The Slammer worm had taken the computer world by surprise, even though there had been a public announcement of the vulnerability that made the worm possible. The vulnerability was in Microsoft's SQL server, and allowed the worm to spread at an alarming rate.
Microsoft had even taken steps to ensure a patch was issued and available before the announcement was made about the vulnerability. When the worm hit on January 25, , it broke all records for the spread of a worm or other virus by doubling in size every 8. The worm eventually infected at least 75, hosts around the globe and hit its maximum scanning rate of 55 million scans per second after only three minutes. The scanning slowed after this point due mostly to the inundation of the various network infrastructures in place at the time.
He remembered the enormous impact the worm had on the computing world and on the Internet in particular. Stego-noise had the ability to make it look like there were a lot more needles in this haystack then really existed. Salah wondered absently if such a virus already existed and how difficult it might be to develop one from scratch.
Perhaps he would consider working on this project another time. The eventual amount of noise a worm of this magnitude could cause would be enormous, allowing years of free communication via covert channels. Yes, he would definitely have to think seriously about pursuing this project. The sharp whistle of the teapot snapped his wandering mind back to the present. And, for a moment, he was just an average college student standing over a teapot, waiting for it to boil. He fought back the brief wish that, for once, he could live a normal life and returned to the task at hand.
The tea was on the top shelf. He wasn't quite sure why he still kept it up there; he had ample cabinet space in his kitchen, but his family had kept it on the top shelf in their kitchen, and he supposed his mind was comforted by small reminders of home. He took a large tablespoon and dumped some of the dark black tea leaves into the boiling water. Picking the pot up off the burner, he placed the pot on a back burner and turned off the flames on the stove.
He was going to need to find out what they already understood. Could he bring a team together under this technology and coordinate an attack? What were his chances of success? He understood that if he expected to get backing from Al Qaeda he would need to demonstrate that his plan was foolproof and would result in a painful wound for the Americans. Walking back to his computer, he read through the e-mails. He was scanning for a single person from the team, a person who had the most likelihood of having discovered the hidden message—Jimmy.
Of course, Jimmy wasn't his real name.
Like Salah, he had chosen a pseudonym for use online. I'll fit in better if my name appears to be normal to them. Ah, there he is, Salah thought as he located the e-mail he had known would be in his box. He and Jimmy had discussed the possibility of using null ciphers in the past.

In fact, it had been Jimmy's idea initially. That's all it said. Nothing more would be needed. Hopefully, the others had also read Salah's e-mail and figured out where the message was. This is going to work, he thought. Salah shut down his computer. He still had studying to do tonight, and he couldn't be up late because he had work in the morning.
Though Salah had received a scholarship from the university, it wasn't enough to cover his books, food, and housing. The job didn't pay a lot, but it was more than enough to make ends meet. The important thing was that it didn't impact his studies or his side project. Working at the bookstore also provided Salah with some needed discounts on textbooks and supplies; discounts that allowed him to take more classes and graduate early.
Shortly after the death of his father, Salah's family had run out of money to pay for school, leaving Salah on his own in a foreign country. It wasn't Salah's style to worry about things out of his control; he was a survivor, and without hesitation, he willingly added this job to his set of responsibilities. He found that it was even a welcome break from his everyday existence.
Hacking a Terror Network
His routine had grown dull between the constant courses, studying, and his after-hours project. The job provided interaction with other students, many of whom Salah was beginning to consider friends. He had tried hard to distance himself and avoid the insidious emotional connections with the students around him, but he was so young. To many he was an average twenty-something student who needed the social interaction that was available only by having friends on campus, but he soon found himself fighting the internal battle to remain introverted and protected.
Salah walked back into the kitchen and prepared to make some dinner.

I'll get some studying done while I eat, he thought. Maybe I'll even watch a little television. He pulled a frying pan from the drawer hiding at the bottom of the old stove and set it on the burner. Reaching inside the refrigerator, he grabbed a carton of eggs. Dinner would be quick and simple tonight. In the world of cyber, there are many different teams and roles to play. Reg Open NOW!
