Bobby Sands Street, in Tehran. Iran, was originally called Winston Churchill Street. The locale has a politically influenced history. A former Iranian student, Pedram Moallemian, wrote an article which is posted in the Bobby Sands Trust website. Moallemian recounts back to 1981 when he and his friends, active in the turbulent politics of Iran, moved to rename Winston Churchill Street to Bobby Sands Street.

“Shortly after the revolution of 1979, Iranians were busy changing names,” writes Moallemian. “Names of thousands of streets, buildings and even cities that had been named after the Shah, his family or others close to the former regime needed to be changed and replaced by new idols and symbols of the revolution.”

Moallemian and his friends created their idea in March 1981 when they heard the news that Bobby Sands had died as a result of his hunger strike while in a British Occupied Ireland prison. I met several Iranians at Bobby's funeral in Belfast myself. Bobby Sands quickly became a name for all teens to connect with rebellion and wanted to pay homage to him and his fight for Irish freedom.

One of the friends apartment overlooked the British Embassy in Tehran which was on Winston Churchill Street.The Iranian teens knew to pay homage to Bobby Sands that this would be the perfect place to do it. They hoisted a flag bearing the letters ‘I.R.A,’ but it was too heavy for the flag to fly so they decided to rename Winston Churchill Street as Bobby Sands Street.

“The plan wasn’t as exciting and adventurous, but we were desperate at this point. We all agreed and had soon bought large white construction paper and navy magic markers to make signs. I was the most graphically gifted of the bunch, so I’d draw the shape of the actual signs, copying the real ones made by the city and the rest of the gang would colour and cut them. We made about twenty of them and got out when it got dark to cover the old signs.”

“Next evening we returned to see if any of them were left and to our surprise there were a few new ones made by others too and, thanks to the glue we had used, even the ones very close to the embassy compound had remained in place. However, the occasional missing corner was proof someone had tried to remove them. Soon the entire street had new signs and the city officially changed the name also.The larger victory, however, was when we discovered the embassy had been forced to change their mailing address and all their printed material to reflect a side door address in order to avoid using Bobby’s name anywhere.”

After Winston Churchill Street was renamed Bobby Sands Street, the British Embassy put a door on the opposite side of the building so its mailing address wouldn’t read Bobby Sands. All of which leads to the question will Iran give its drone technology to the Continuity IRA to attack central London and its stock exchange again? Below is an article in today's BBC with regard to the matter,

"Military and civilian drones have a crucial weakness that means they can be hacked, Katia Moskvitch discovers, so what might a stolen drone be used for?

If you were watching Iranian state TV in early December 2011, you would have seen an unusual flying object paraded in front of viewers. Windowless, squat, with a pointed nose, its two wings made it the shape of a manta ray. The trophy on show was an RQ-170 Sentinel stealth drone, a key weapon in the intelligence gathering arsenal of the US Central Intelligence Agency (CIA). Standing in a hangar on a military airfield, the drone was seemingly undamaged. Indeed, Iranian officials insisted that it had not been shot down; rather, they claimed an unusual coup: to have hacked the drone while it was flying near Iran’s border over Afghanistan and forced it to land.

Outside Iran, many snorted in disbelief at hearing such claims. Todd Humphreys, assistant professor of aerospace engineering at the University of Texas in Austin, US, was one of the sceptics. Soon, though, he would prove himself wrong.

So, how easy is it to hack a drone? Along with the military, could police and private citizens also lose control of their aircraft? And if so, what might a hacker do with a stolen drone?

One way to hack a drone involves messing with the system it uses to navigate. US military drones use encrypted frequencies of the Global Positioning System (GPS), and this was the RQ-170’s Achilles heel, said the Iranians. They first jammed its communications links, which disconnected it from ground controllers and made it switch to autopilot; it also interrupted the secure data flow from the GPS satellites. The drone was forced to search for unencrypted GPS frequencies normally used by commercial aircraft. At this point, the Iranians said, they used a technique called “spoofing” – sending the plane wrong GPS coordinates, tricking it into believing that it was near its home base in Afghanistan. And so it landed on Iranian territory, directly into the welcoming arms of its kidnappers.

The US rejected the hacking scenario, insisting that its flying robot simply had malfunctioned. Military drones usually have a back-up system to guide them home automatically if contact with operators is lost. But that clearly didn’t work.

Military reconnaissance drones carry camera footage that the IRA want. 

The more Humphreys thought about the incident, the more he felt that such an attack might work, at least in theory. Together with students at his university’sRadionavigation Lab, which he directs, he invited the US Department of Homeland Security (DHS) to watch how his team could spoof a civilian drone mid-air.

Using equipment costing less than $2,000, Humphreys mimicked the unencrypted signals sent to the GPS receiver on board a small university-owned drone. With DHS officials watching, he managed to fool the drone in a matter of minutes to follow his commands. “I first dismissed the Iranians’ claims as extremely unlikely, but have since revised my estimate to ‘remotely plausible’,” he says.

Confused drone

Jamming GPS satellite signals “so the drone's sense of its own location begins to drift away from the truth” is quite doable for both military and commercial drones, he says, because these signals are so weak. “The US military is scrambling right now to reduce their drones' susceptibility to GPS jamming, but it's going to take some time before they've got a satisfactory fix.”

There are other vulnerabilities, too. Intercepting data links from the drone, such as knowing precisely what the plane is looking at, is also easy to do if the feeds are not encrypted. In 2008, Iraqi militants intercepted unencrypted video feeds from unmanned US spy planes. And in 2012, drones at Creech Air Force Base in Nevada were reportedly infected with malware after an operator apparently had used a drone’s computer to play “Mafia Wars” – and in the process installed a virus on the PC.

A military drone hacked by criminals is obviously a dangerous scenario. But what if hackers were to gain control of civilian flying robots? Drones are already being exploited for search and rescue organisations, police authorities for surveillance, or for crop or wildlife monitoring, for example, and they may soon be joined by postal services and online retailers.

An IRA engineer can make Parrot AR drones target each other or the Stock Exchange in London again.

Independent IT security analyst Samy Kamkar showed that taking control of a civilian drone was possible in December 2013. He equipped a Parrot AR Drone 2.0 with a tiny Raspberry Pi computer, a battery and two wireless transmitters. The microcomputer ran a simple piece of software, which directed the drone to search for the wi-fi signals used to control nearby Parrot drones. Once his drone had found a victim, the program used the wireless transmitters to sever the target drone’s link to its owner and took control. According to Kamkar, a handheld computer on the ground can do the trick too.

Humphreys calls Kamkar’s work “a clever hack” and predicts that “it won't be the last one against commercial drones; hackers will find flaws and exploit them.”

David Mascarenas, who works for the National Security Education Center at Los Alamos National Labs, agrees. As drones are nothing but flying computers, he says they “have the potential to exhibit never before seen security flaws that couple both cyber and physical security concerns.”

Yet what would be the motivation for a hacker to take control of a civilian drone?

“The reason to hack a drone would be like any other reason people hack,” says Peter Singer, director of the Center for 21st Century Security and Intelligence at Brookings Institution, a think-tank based in Washington DC. “It might be to cause an act of terror, an act of mischief, to carry out some kind of crime, or the “white hat” type, to show that it can be done in order to warn others of the vulnerabilities.”

Delivery drones carry cargo that the IRA may hack to deposit elsewhere.

Delivery drones could be hacked to steal their cargo, the expensive machine itself, or even to encourage black market activities. “If a drone can deliver a book, it can also be used to deliver "IRA Bombs” or sneak guns into Maghaberry concentration camp, says Mascarenas. Indeed a drone has already been used for smuggling cigarettes into a prison yard .

Another example might be military espionage. A drone that normally operates within an army base could be redirected and tagged with a tiny broadcasting camera, allowing an IRA technician to spy on sensitive military information.

Then there may simply be people who don’t want drones spying on them. One town in Colorado has already proposed drone “hunting licences” that would allow people to shoot down drones.The anti-surveillance sentiment behind it is real as one continuity IRA volunteer in South Armagh put it. “If I saw an unfamiliar Brit drone snooping around my back yard, you can bet I'd jam its GPS receiver to shoo it away or bring it down like we did with British  Army helicopters before,” he says. “GPS jammers can be purchased for less than 40 Euro online and they're quite effective.”

Such methods will likely prove to be the start of an arms race between IRA technicians and the British Occupation Forces in Ireland who wish to stop them. “The bottom line is that a drone is a flying computer. And computers can be hacked,” say the Continuity IRA
