GPS spoofing affecting civilians in the Middle East

September 2024: “Since the start of the Gaza war, the Israel Defense Forces (IDF) has been deploying a tactic known as GPS “spoofing”, designed to fool enemy missiles and rockets that rely on the global positioning system technology to aim at their target” reports the Australian Broadcasting Corporation (ABC). Their GPS spoofing has also affected civilians through disrupting “civil infrastructure, commercial aircraft and even dating and food delivery apps.”

Their GPS spoofing causes devices in the area to resolve as being located “[o]n the tarmac of Beirut’s international airport” or an industrial estate in Cairo, Egypt. The RNL’s Dr. Humphreys says these locations are “fairly arbitrary.” Research at the RNL has determined the location of at least one of the spoofing transmitters to be in the Ein Shemer Airfield in northern Israel.

One major disruption is for aviation. Dr. Humphreys “says because of the frequency, pilots have become accustomed to this and sometimes shut off the alarms or the GPS system, which is dangerous, despite there being no accidents so far” according to the ABC. “In July, Lebanon filed a complaint to the United Nations and the International Telecommunication Union (ITU) over the GPS spoofing, which also affects aircraft transiting the Mediterranean.”

The ABC reports that “it’s not clear if this practice is considered legal or not as the International Telecommunications Union ‘has spoken out both sides of its mouth'”, according too Dr. Humphreys. He says “[o]n the one hand, [the ITU] says, ‘Thou shalt not transmit any signals in the GNSS bands. These are sacred bands, bands reserved for aviation, for safety of life.’ But in a different portion of the … constitution, they basically give carte blanche to countries over security threats.” This would allow any country to disrupt GPS, even beyond its borders and for civilians, if they claim it is for security reasons.

Electronic Warfare : A concern for airlines, pilots, and officials

September 2024: As GPS jamming and spoofing continue, pilots, airlines, and officials voice their concerns. The WSJ reports that “[t]he number of flights affected daily has surged from a few dozen in February to more than 1,100 in August,” based on data from SkAI Data Services and Zurich University of Applied Sciences. While officials say spoofing hasn’t posed major safety risks, since pilots are trained to handle situations without GPS by relying on backup systems, it still takes pilots’ attention away in case of other concurrent emergencies.

The RNL’s Dr. Humphreys says “[t]hese pilots are doing double duty in the cockpit,” in response to reports from pilots. He also says “[t]his is embarrassing for the airline industry, for the carriers and for the FAA,” in response to the slow movements from industry and regulators to “harden planes against spoofing.”

While the FAA said it “found no proof of intentional interference” as reported by the WSJ, there have been instances in the US of GPS interference causing issues, like a case in October 2022 at Dallas Fort Worth International Airport. Outside the US, Europe is reporting disruptions due to GPS spoofing but say no flights have been endangered. For more on the story, visit the WSJ here, or the transcript here.

GPS is under attack

July 2024: As GPS service is threatened by spoofing and jamming, many modern day operations dependent on it are being threatened as well. As reported by the New York Times, in the last year over 60, 000 commercial aircraft have been victims of GPS spoofing. Our dependence on GPS and GNSS in general spans from emergency services like ambulances, communications with cell phones, and many other modern day services. Despite the importance of the service GPS provides us, the U.S. “has no civilian backup system” for it.

According to the article, the U.S. is lagging behind competing GNSS systems by replacing the aging satellites slowly while other countries develop “newer alternatives.” Europe’s Galileo system authenticates its signals. China’s Beidou system has the most satellites, and the country has built land-based infrastructure meant to support their system, but also act as a backup. “A U.S. backup plan was proposed a decade ago but never took off. New American technologies are in development but could take years before they are widely adopted.” For more on this, visit the article here.

The RNL has already found that a major source of spoofing in the Middle East is an Israeli air base with a speculated main purpose of disrupting Hamas rockets, but also affecting commercial flights in the region. According to another New York Times article, “the Israeli military declined to comment” when asked about it. As spoofing becomes more prevalent, some regions are more affected than others, like the Middle East, or the Baltics. For more visit the article here.

Israel’s GPS spoofing disrupting all GPS-dependent operations

July 2024: GPS spoofing signals in the Eastern Mediterranean have reportedly been affecting areas in Lebanon, Israel, Syria, Jordan, Egypt, Turkey and Cyprus. These signals affect various operations, the most worrying being aviation. “Researchers from SkAI Data Services, using information from the OpenSky Network, detected almost 2,000 spoofed planes” over a recent 72-hour period. The RNL’s researchers have geolocated the transmitter to an air base in northern Israel.

Beyond commercial aviation, the spoofing affects Hezbollah’s Iran-supplied “arsenal of GPS-guided munitions, including drones,” with Israeli military spokesman Rear Adm. Daniel Hagari saying “[they] are aware that these disruptions cause inconveniences, but it is a vital and necessary tool in [their] defensive capabilities.” In addition to the intended military targets, and unintended commercial aviation, the spoofing affects maritime shipping and everyday civilians (Google maps, food delivery, dating apps). The RNL’s Dr. Humphreys says “his is an attempt to use the most potent form of GPS electronic and navigational warfare. Yet they cannot contain the spoofing to just the borders of Israel, because they need it to overwhelm receivers that are designed to resist such spoofing. They need to have many times the traditional power to overcome a GPS receiver, so the signals are being felt all the way out to Cyprus.” For more details on the story, visit the article here.

First instance of jamming for a commercial transatlantic flight

June 2024: A flight from Madrid to Toronto was the victim of a GPS Jamming attack over the Atlantic. The attack prevented the pilot from ascending to a higher altitude. The source has yet to be identified. The RNL’s Dr. Humphreys said the incident was a “more deliberate attack against commercial aircraft” rather than “the usual spillover of electronic warfare”. He also weighed in saying “it could be individual hackers who have learned from media reports how vulnerable commercial aircraft are to GPS jamming… It’s hard to see why a state actor would do this, though I don’t deny that Russia’s penchant for hybrid warfare that involves creating whatever mayhem it can in the West.” For more, visit the original article here.

Spoofing in the Mediterranean disrupting everyday activities

June 2024: Reports continue coming in of GNSS spoofing in the eastern Mediterranean. Accounts from the island of Cyprus range from delivery service timing being absurd, to commercial aircraft and ships having their GNSS services disrupted. The main effect, according to a Forbes article, is having one’s location spoofed to the Beirut Airport. The RNL’s Dr. Humphreys says “it’s not just Russia, China, and Iran anymore – GPS spoofing has gone mainstream.” For more on the story, visit the Forbes article here.

How GPS warfare is playing havoc with civilian life

May 2024: “NATO has blamed Russia for such GNSS interruptions across large parts of Europe,
including one that affected a flight carrying the UK defense secretary. Conflict in the Middle East has also increased GPS manipulation in the region. Some world leaders, including Russia’s Vladimir Putin, reportedly use mobile jammers for protection when travelling.” The RNL’s Dr. Humphreys says “This is a dangerous situation. Pilots can become so confused about their location, they end up having to call aircraft control and ask for turn-by-turn directions . . . It’s past the line of just a nuisance.” For more on the story visit the Financial Times article here.

The Dangerous Rise of GPS Attacks

May 2024: “Attacks against GPS, and the wider GNSS category, come in two forms. First, GPS jamming looks to overwhelm the radio signals that make up GPS and make the systems unusable. Second, spoofing attacks can replace the original signal with a new location—spoofed ships can, for example, appear on maps as if they’re at inland airports. Within the Baltic region, 46,000 aircraft showed potential signs of jamming between August 2023 and March this year, according to reports and data from tracking service GPSJam. Benoit Figuet, an academic at the Zurich University of Applied Sciences who also runs a live GPS spoofing map, says there have been an additional 44,000 spoofing incidents logged since the start of this year.”

The RNL’s Zach Clements states “the biggest change in the past six months is definitely the amount of spoofing that’s going on. For the first time, we’re seeing widespread disruptions in civil aviation, especially in the Eastern Mediterranean, the Baltics, and the Middle East. In prior years, there were reports of spoofing impacting marine vessels, but not aviation.” For more on the subject visit the Wired article here.

Israel GPS spoofing for Defense also affecting civilian planes

April 2024: The RNL’s Dr. Humphreys speaking to NPR says “I like to say that spoofing is the new jamming.” GPS interference is now not only conducted by usual suspects, but also U.S. ally Israel. Israel themselves have reportedly acknowledged blocking GPS for defensive purposes since last October. Dr. Humphreys and the RNL have “traced the origin of the false signals using data collected from receivers in low Earth orbit,” with the data pointing to a particular airbase in Israel, according to Dr. Humphreys.

“The most recent guidance from the main carriers … is that you have to be shutting off GPS inputs to your system long before you’re in conflict areas,” says Dr. Humphreys. According to the NPR article, “Members of the United Nations’ International Telecommunications Union (ITU), which regulates communication technology, passed a motion in December in Dubai that for the first time allows spoofing of GPS for national security reasons.”

Specifically in Israel “most of the spoofing around Israel is directing aircraft to believe that they are at the Beirut airport,” with a possible reason being “commercially available drones, which can be modified for attack, are built to freeze in the vicinity of an airport.” For more details on the story, visit the article and audio interview here, or a short video here.
