How Iran hijacked a US stealth drone

Posted on December 15, 2011 - 13:52 by Trent Nouveau

The Iranian military recently managed to hijack an American stealth drone by exploiting a well-known navigational vulnerability in the RQ-170 Sentinel, aka The Beast of Kandahar.

According to an Iranian engineer, electronic warfare specialists cut off US contact with the drone before reconfiguring the Sentinel's GPS coordinates and landing it in Iranian territory. 

How Iran hijacked a US stealth drone"The GPS navigation is the weakest point," the engineer told the Christian Science Monitor.

"By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain."

The "spoofing" technique, said the engineer, utilized precise latitudinal and longitudinal data, "forcing the drone to land on its own where we wanted it to, without having to (zabranjeno) the remote-control signals and communications," from the US control center.

Former US Navy electronic warfare specialist Robert Densmore told the CS Monitor the digital hijacking scenario detailed by the unnamed Iranian engineer was entirely plausible.

"Even modern combat-grade GPS [is still] very susceptible to manipulation," Densmore confirmed. 

He also noted it was "certainly possible" to recalibrate the GPS on a drone so that it flies on a different course than originally programmed.

"[Obviously], I wouldn't say it's easy, but the technology is there."

Dobro su se upecali. Mr. Green

The US Air Force reportedly plans to deploy a new offensive, radar-evading drone in Afghanistan after Iran downed one of its stealth drones, which was in violation of the Islamic Republic's airspace.

The Predator C Avenger is designed to evade detection and carry payloads of the weight of a bunker buster, the international aerospace weekly Flight International reported on its website on December 12.

The US Air Force has ordered a single Predator C Avenger -- produced by General Atomics Aeronautical Systems. Inc. -- for deployment in Afghanistan.

"This aircraft will be used as a test asset and will provide a significantly increased weapons and sensors payload capacity on an aircraft that will be able to fly to targets much more rapidly than the MQ-9 [Reaper] UAS," the US Air Force said in a statement.

Alongside four weapon stations on each wing, the drone has an internal weapons bay, which provides “greater flexibility and will accommodate a large selection of next generation sensor and weapons payloads," it added.

The newest aircraft is jet-powered and particularly characterized by its capability of carrying a total payload of more than 907 kilograms -- almost the weight of a GBU-24 penetrator bunker buster bomb.

Analysts say the fact that Taliban militants have no radars to detect such aircraft robs Washington of excuses to deploy the stealth drone in the war-torn country.

The prospect of the deployment of the highly-capable Predator C comes after Iran successfully brought down a US RQ-170 stealth drone recently as the aircraft was flying over the northeastern Iranian city of Kashmar, some 250 kilometers (156 miles) away from the Afghan border.


TEHRAN — Iran is to insert its first domestically produced uranium fuel into its Tehran reactor by mid-February, Foreign Minister Ali Akbar Salehi said in comments published by the IRNA state news agency on Thursday.

“Within the next two months the first fuel plate which is produced with the 20% enriched uranium will be placed in Tehran’s research reactor,” Salehi, who previously headed Iran’s nuclear organisation, was quoted as saying.

His statement was an excerpt from a longer interview to be released “soon,” IRNA said.

The West — which fears Iran’s nuclear programme masks a push to build atomic weapons despite repeated denials from Tehran — is sceptical that the Islamic republic has the technology to make fuel plates.

Four sets of UN sanctions and additional Western sanctions have been imposed to pressure Iran to halt its nuclear programme.

Iran has been working to enrich its stock of 3.5% low-enriched uranium to 20%, which it says it needs for research and medical purposes.

Currently, the research reactor runs on fuel imported from Argentina in 1993, but that is nearly depleted. Iran’s other nuclear plant, an energy reactor at Bushehr, runs on fuel bought from Russia.

Iran was to produce its first lot of 20 percent-enriched uranium plates for the Tehran reactor in September this year, but that date passed with no result.

Salehi was quoted by IRNA as saying in mid-October that Iran would produce the plates within months.

The International Atomic Energy Agency in November released its most damning report yet on Iran’s nuclear activities, saying it had evidence suggesting research into atomic warheads had been carried out.

After Iran announced to the IAEA that it had run out of nuclear fuel for its research reactor in Tehran, the Agency proposed a deal according to which Iran would send 3.5%-enriched uranium and receive 20-percent-enriched uranium from potential suppliers in return, all through the UN nuclear watchdog agency.

The proposal was first introduced on October 1, 2010, when Iranian representatives and diplomats from the Group 5+1 held high-level talks in Geneva.

But France and the United States, as potential suppliers, stalled the talks soon after the start. They offered a deal which would keep Tehran waiting for months before it could obtain the fuel, a luxury of time that Iran could afford as it was about to run out of 20-percent-enriched uranium.

Iranian lawmakers rejected the deal after technical studies showed that it would only take two to three months for any country to further enrich the nuclear stockpile and turn it into metal nuclear plates for the Tehran Research Reactor, while suppliers had announced that they would not return fuel to Iran any less than seven months.


A grim Ministry of Defense bulletin issued to Prime Minister Putin and President Medvedev today states that President Hu has “agreed in principal” that the only way to stop the West’s aggression led by the United States is through “direct and immediate military action” and that the Chinese leader has ordered his Naval Forces to “prepare for warfare.”

Hu’s call for war joins Chinese Rear Admiral and prominent military commentator Zhang Zhaozhong who, likewise, warned this past week that: “China will not hesitate to protect Iran even with a Third World War,” and Russian General Nikolai Makarov who grimly stated last week: “I do not rule out local and regional armed conflicts developing into a large-scale war, including using nuclear weapons.”

A new US intelligence report has also stated that China has up to 3000 nuclear weapons compared with general estimates of between 80 and 400. To further pour more gasoline on the fire, the Washington Times has just reported that North Korea is making missile able to hit the US.

The raising of global tensions between the East and West was exploded this past fortnight when Russian Ambassador Vladimir Titorenko and two of his aides retuning from Syria were brutally assaulted and put in hospital by Qatar security forces allegedly aided by CIA and British MI6 agents attempting to gain access to diplomatic pouches containing information from Syrian intelligence that the United States was flooding Syria and Iran with the same US-backed al Qaida mercenaries who toppled the Libyan government.

Rezultati ispitivanja "Američke konferencije gradoonačelnika 2011" o gladi i beskućništvu ukazuje na to da samo u četiri od 29 gradova u kojima je obavljeno ispitivanje nije prijavljen porast zahtjeva za pomoć u hrani u periodu između septembra 2010. godine i avgusta 2011. godine.

Polovina od ovog broja su porodični ljudi, dok je 26 odsto u radnom odnosu. Starije osobe čine 19 odsto, dok su preostalih 11 odsto beskućnici.

Apparently Iran had blinded a US spy satellite!

Exclusive: Iran hijacked US drone, says Iranian engineer

Istanbul, Turkey

Iran guided the CIA‘s “lost” stealth drone to an intact landing inside hostile territory by exploiting a navigational weakness long-known to the US military, according to an Iranian engineer now working on the captured drone’s systems inside Iran.

Iranian electronic warfare specialists were able to cut off communications links of the American bat-wing RQ-170 Sentinel, says the engineer, who works for one of many Iranian military and civilian teams currently trying to unravel the drone’s stealth and intelligence secrets, and who could not be named for his safety.

Using knowledge gleaned from previous downed American drones and a technique proudly claimed by Iranian commanders in September, the Iranian specialists then reconfigured the drone’s GPS coordinates to make it land in Iran at what the drone thought was its actual home base in Afghanistan.

IN PICTURES: America’s Predator drones

“The GPS navigation is the weakest point,” the Iranian engineer told the Monitor, giving the most detailed description yet published of Iran’s “electronic ambush” of the highly classified US drone. “By putting noise [jamming] on the communications, you force the bird into autopilot. This is where the bird loses its brain.”

The “spoofing” technique that the Iranians used – which took into account precise landing altitudes, as well as latitudinal and longitudinal data – made the drone “land on its own where we wanted it to, without having to (zabranjeno) the remote-control signals and communications” from the US control center, says the engineer.

The revelations about Iran’s apparent electronic prowess come as the US, Israel, and some European nations appear to be engaged in an ever-widening covert war with Iran, which has seen assassinations of Iranian nuclear scientists, explosions at Iran’s missile and industrial facilities, and the Stuxnet computer virus that set back Iran’s nuclear program.

Now this engineer’s account of how Iran took over one of America’s most sophisticated drones suggests Tehran has found a way to hit back. The techniques were developed from reverse-engineering several less sophisticated American drones captured or shot down in recent years, the engineer says, and by taking advantage of weak, easily manipulated GPS signals, which calculate location and speed from multiple satellites.

RECOMMENDED: Downed US drone: How Iran caught the ‘beast’

Western military experts and a number of published papers on GPS spoofing indicate that the scenario described by the Iranian engineer is plausible.

“Even modern combat-grade GPS [is] very susceptible” to manipulation, says former US Navy electronic warfare specialist Robert Densmore, adding that it is “certainly possible” to recalibrate the GPS on a drone so that it flies on a different course. “I wouldn’t say it’s easy, but the technology is there.”

In 2009, Iran-backed Shiite militants in Iraq were found to have downloaded live, unencrypted video streams from American Predator drones with inexpensive, off-the-shelf software. But Iran’s apparent ability now to actually take control of a drone is far more significant.

Iran asserted its ability to do this in September, as pressure mounted over its nuclear program.

Gen. Moharam Gholizadeh, the deputy for electronic warfare at the air defense headquarters of the Islamic Revolutionary Guard Corps (IRGC), described to Fars News how Iran could alter the path of a GPS-guided missile – a tactic more easily applied to a slower-moving drone.

“We have a project on hand that is one step ahead of jamming, meaning ‘deception’ of the aggressive systems,” said Gholizadeh, such that “we can define our own desired information for it so the path of the missile would change to our desired destination.”

Gholizadeh said that “all the movements of these [enemy drones]” were being watched, and “obstructing” their work was “always on our agenda.”

That interview has since been pulled from Fars’ Persian-language website. And last month, the relatively young Gholizadeh died of a heart attack, which some Iranian news sites called suspicious – suggesting the electronic warfare expert may have been a casualty in the covert war against Iran.

Iran’s growing electronic capabilities

Iranian lawmakers say the drone capture is a “great epic” and claim to be “in the final steps of breaking into the aircraft’s secret code.”

Secretary of Defense Leon Panetta told Fox News on Dec. 13 that the US will “absolutely” continue the drone campaign over Iran, looking for evidence of any nuclear weapons work. But the stakes are higher for such surveillance, now that Iran can apparently disrupt the work of US drones.

US officials skeptical of Iran’s capabilities blame a malfunction, but so far can’t explain how Iran acquired the drone intact. One American analyst ridiculed Iran’s capability, telling Defense News that the loss was “like dropping a Ferrari into an ox-cart technology culture.”

Yet Iran’s claims to the contrary resonate more in light of new details about how it brought down the drone – and other markers that signal growing electronic expertise.

A former senior Iranian official who asked not to be named said: “There are a lot of human resources in Iran…. Iran is not like Pakistan.”

“Technologically, our distance from the Americans, the Zionists, and other advanced countries is not so far to make the downing of this plane seem like a dream for us … but it could be amazing for others,” deputy IRGC commander Gen. Hossein Salami said this week.

According to a European intelligence source, Iran shocked Western intelligence agencies in a previously unreported incident that took place sometime in the past two years, when it managed to “blind” a CIA spy satellite by “aiming a laser burst quite accurately.”

More recently, Iran was able to hack Google security certificates, says the engineer. In September, the Google accounts of 300,000 Iranians were made accessible by hackers. The targeted company said “circumstantial evidence” pointed to a “state-driven attack” coming from Iran, meant to snoop on users.

(zabranjeno)ing the protected GPS coordinates on the Sentinel drone was no more difficult, asserts the engineer.

US knew of GPS systems’ vulnerability

Use of drones has become more risky as adversaries like Iran hone countermeasures. The US military has reportedly been aware of vulnerabilities with pirating unencrypted drone data streams since the Bosnia campaign in the mid-1990s.

Top US officials said in 2009 that they were working to encrypt all drone data streams in Iraq, Pakistan, and Afghanistan – after finding militant laptops loaded with days’ worth of data in Iraq – and acknowledged that they were “subject to listening and exploitation.”

Perhaps as easily exploited are the GPS navigational systems upon which so much of the modern military depends.

“GPS signals are weak and can be easily outpunched [overridden] by poorly controlled signals from television towers, devices such as laptops and MP3 players, or even mobile satellite services,” Andrew Dempster, a professor from the University of New South Wales School of Surveying and Spatial Information Systems, told a March conference on GPS vulnerability in Australia.

“This is not only a significant hazard for military, industrial, and civilian transport and communication systems, but criminals have worked out how they can jam GPS,” he says.

The US military has sought for years to fortify or find alternatives to the GPS system of satellites, which are used for both military and civilian purposes. In 2003, a “Vulnerability Assessment Team” at Los Alamos National Laboratory published research explaining how weak GPS signals were easily overwhelmed with a stronger local signal.

“A more pernicious attack involves feeding the GPS receiver fake GPS signals so that it believes it is located somewhere in space and time that it is not,” reads the Los Alamos report. “In a sophisticated spoofing attack, the adversary would send a false signal reporting the moving target’s true position and then gradually walk the target to a false position.”

The vulnerability remains unresolved, and a paper presented at a Chicago communications security conference in October laid out parameters for successful spoofing of both civilian and military GPS units to allow a “seamless takeover” of drones or other targets.

To “better cope with hostile electronic attacks,” the US Air Force in late September awarded two $47 million contracts to develop a “navigation warfare” system to replace GPS on aircraft and missiles, according to the Defense Update website.

Official US data on GPS describes “the ongoing GPS modernization program” for the Air Force, which “will enhance the jam resistance of the military GPS service, making it more robust.”

Why the drone’s underbelly was damaged

Iran’s drone-watching project began in 2007, says the Iranian engineer, and then was stepped up and became public in 2009 – the same year that the RQ-170 was first deployed in Afghanistan with what were then state-of-the-art surveillance systems.

In January, Iran said it had shot down two conventional (nonstealth) drones, and in July, Iran showed Russian experts several US drones – including one that had been watching over the underground uranium enrichment facility at Fordo, near the holy city of Qom.

In capturing the stealth drone this month at Kashmar, 140 miles inside northeast Iran, the Islamic Republic appears to have learned from two years of close observation.

Iran displayed the drone on state-run TV last week, with a dent in the left wing and the undercarriage and landing gear hidden by anti-American banners.

The Iranian engineer explains why: “If you look at the location where we made it land and the bird’s home base, they both have [almost] the same altitude,” says the Iranian engineer. “There was a problem [of a few meters] with the exact altitude so the bird’s underbelly was damaged in landing; that’s why it was covered in the broadcast footage.”

Prior to the disappearance of the stealth drone earlier this month, Iran’s electronic warfare capabilities were largely unknown – and often dismissed.

“We all feel drunk [with happiness] now,” says the Iranian engineer. “Have you ever had a new laptop? Imagine that excitement multiplied many-fold.” When the Revolutionary Guard first recovered the drone, they were aware it might be rigged to self-destruct, but they “were so excited they could not stay away.”

Avtobaza, jammer-i, Rq-170...

Citat:Detecting and tracking?

As reported early November in DMI, the Russian supplied the Iranian Air defense forces with the Avtobaza 1L222 ELINT + Jammer moblie systems. Unlike the well known Czech Vera and Ukranian Kalchuga, the Kvant Avtobaza is unique due to its co-integrated Jammer. While the passive receivers operate in the 8-18GHz bands over ranges up to 150km. The RQ-170 telemetry band is presumably ECCM capable C-band (0.5-1GHz), However the covert drone was relaying imagery over the Ku band satellites. This could have been the signal which alerted the Avtobaza.
