Solar Warden
A Scottish systems administrator hacked 97 US military and NASA computers from his girlfriend's aunt's house. What he found ended his life as he knew it.
Gary McKinnon was born in Glasgow, Scotland in February 1966. He became interested in computers at age 14 when he was given an Atari 400. By 2001, he was a 35-year-old unemployed systems administrator living in north London, spending his nights searching for something the US government didn't want anyone to find.
McKinnon was not a sophisticated hacker. He had no formal hacking background. He was a self-taught sysadmin who could write Perl scripts and knew how Windows networks worked. What he had was conviction — he believed the US government was suppressing two things: evidence of extraterrestrial contact and free energy technology. He decided to look for both.
Using the handle "Solo," McKinnon began scanning US government networks from a dial-up internet connection. He was sitting in his girlfriend's aunt's house in north London, smoking weed in a dressing gown at 4am, connected through a 56K modem. The most powerful military in human history was about to be compromised by a man who described his own skill level as: "I was good with computers."
McKinnon wrote a Perl script that could scan 65,000 machines in just over eight minutes. It searched for one thing: Windows computers with administrator accounts that had blank passwords. He found hundreds.
The technique was devastatingly simple. McKinnon described his scanning process in a BBC interview:
"The first scan would only identify Windows machines. After that you run a secondary scan saying, 'OK, this is a Windows machine, but can I actually talk to it across the port?' A few would go, and a few would still be left open. Then after that, there's a third stage where you say, 'OK, I can talk to them, is there a blank password?' Then you do your harvesting, and you end up with a big list of administrator-level, powerful accounts."
Between February 2001 and March 2002 — a period of 13 months — McKinnon accessed 97 computers belonging to the US Army, Navy, Air Force, NASA, and the Department of Defense. He used commercially available remote desktop software to connect through the blank administrator accounts. No zero-day exploits. No advanced tools. Just a Perl script and the assumption that the most powerful military on Earth wouldn't bother to set passwords on its machines.
He was right.
The remaining two systems belonged to the Department of Defense and the US Air Force. McKinnon had blanket access to machines controlling military district networks in Virginia and Washington, the Naval Weapons Station Earle in New Jersey (responsible for replenishing munitions for the entire deployed Atlantic fleet), and NASA's Johnson Space Center — where satellite imagery was processed.
"I reckoned maybe they might even thank me because I could say 'look at all these blank passwords, you were lucky it was me, not al-Qaeda.'"
Deep inside Pentagon file systems, McKinnon found an Excel spreadsheet. It was titled "Non-Terrestrial Officers." It contained names and ranks of US military personnel who did not appear in any publicly accessible military database.
McKinnon described finding the spreadsheet during multiple interviews over the following two decades. The document listed names, ranks, and what appeared to be duty assignments. The officers were not registered in any conventional military database — not Army, not Navy, not Air Force. The prefix "non-terrestrial" was used in the file itself.
Alongside the officer list, McKinnon found a second document. This one was titled "fleet-to-fleet transfers" — or, in some of his retellings, references to "material transfers between ships." The document listed ship names that did not correspond to any vessel in the US Navy registry.
The naming convention was unusual. US Navy ships are designated with two S's — USS, for "United States Ship." The vessels in McKinnon's document carried three S's — USSS — which researchers have speculated stands for "United States Space Ship."
The program these officers and ships allegedly belonged to was referenced under the name Solar Warden. McKinnon described it as a secret space-based military operation run through the United States Naval Network and Space Operations Command (NNSOC). Approximately 300 military personnel were reportedly assigned to it.
A NASA photographic expert named Donna Hare had previously testified that there was a department at NASA's Johnson Space Center — in Building 8 — where high-resolution satellite images were routinely processed. Part of that processing, she claimed, involved airbrushing anomalous objects out of the imagery before public release. McKinnon went looking for Building 8's files. He found them.
McKinnon logged into a NASA system and navigated to the image directories. He found folders organized into two categories: filtered and unfiltered — or, as he described it in other interviews, "processed" and "raw." The filtered images were the versions released to the public. The unfiltered images were the originals.
He opened one of the raw files. His dial-up connection could only render the image slowly, so he set his desktop to 4-bit color and low resolution to speed up the display. What loaded was a high-resolution photograph taken from above Earth's atmosphere — and hovering above the hemisphere was an object.
"It was a silvery, cigar-shaped object with geodesic spheres on either side. There were no visible seams or riveting. There was no reference to the size of the object, and the picture was taken presumably by a satellite looking down on it. It didn't look manmade or anything like what we have created."
Before McKinnon could save or screenshot the image, his remote session was detected and terminated by a NASA operator who was monitoring the same system. The connection was cut. McKinnon never retrieved the image.
For over two decades, McKinnon maintained a consistent account of what he found. In 2024, journalist Jesse Michels conducted the most detailed on-camera interview with McKinnon to date, walking through every claim methodically.
What makes McKinnon's account unusual is its consistency. Over 20+ years of interviews, legal proceedings, and media appearances, the core details have not changed: the Perl script scanning for blank passwords, the "Non-Terrestrial Officers" spreadsheet, the fleet-to-fleet transfers with USSS-prefix ship names, the cigar-shaped object in the unfiltered NASA image, and the reference to a program called Solar Warden.
McKinnon has also been transparent about the limits of what he saw. He did not download the spreadsheet. He did not save the image. He was operating on a 56K dial-up connection from London, remoting into systems across the Atlantic. He saw what he saw in real time and then lost access. The evidence exists only in his testimony.
On the morning of March 19, 2002, officers from the UK's National Hi-Tech Crime Unit arrived at McKinnon's home and arrested him. He was cooperative. He assumed the charges would be minor — a UK offense carrying a maximum of six months. He was wrong.
The United States wanted him extradited. The charges were federal. Paul McNulty, US Attorney for the Eastern District of Virginia, called it "the biggest military computer hack of all time." McKinnon faced up to 70 years in a US federal prison.
| Charge | Detail |
|---|---|
| Systems accessed | 97 computers across Army, Navy, Air Force, NASA, DoD |
| Damage claimed | $700,000 — $900,000 in investigation and restoration |
| Most serious incident | Naval Weapons Station Earle — 300 computers taken offline for a week, Sept 2001 |
| Timing | Earle shutdown occurred 12 days after the September 11 attacks |
| Potential sentence | Up to 70 years in US federal prison |
| US characterization | "The biggest military computer hack of all time" |
The Naval Weapons Station Earle incident was the most damaging charge. Earle is responsible for replenishing munitions and supplies for the entire deployed Atlantic fleet. McKinnon had stolen 950 passwords from seven servers on the Earle network. When the system was shut down, it disrupted operations at a moment when the US military was on maximum alert following 9/11.
McKinnon has maintained that he did not intentionally cause damage — that shutdowns were the result of his clumsy navigation and the military's own poor security. The US government did not see it that way. What followed was a legal battle that would last ten years.
From 2002 to 2012, Gary McKinnon fought extradition to the United States in what became one of the highest-profile human rights cases in British legal history. It ended with a decision that had never been made before under the 2003 US-UK Extradition Act.
It was the first time an extradition had been blocked since the signing of the 2003 Extradition Act between the United States and the United Kingdom. The UK's Crown Prosecution Service subsequently announced that McKinnon would not face charges in the UK either, citing insufficient evidence to prosecute domestically.
McKinnon was free. He was not cleared. He was never tried. The case was simply closed without resolution. The US government never got to question him under oath about what he found. McKinnon never got to present his evidence in a courtroom. The spreadsheets, the image, the fleet — none of it was ever submitted to legal scrutiny.
"Mr McKinnon's extradition would give rise to such a high risk of him ending his life that a decision to extradite would be incompatible with Mr McKinnon's human rights."
McKinnon didn't arrive at Building 8 by accident. He went there because someone else had already described what happened inside it — under oath, on camera, years before his hack.
Donna Hare was a NASA design illustrator and technical artist who held a Secret clearance and worked as a contractor at Johnson Space Center throughout the 1970s. In 2001 — the same year McKinnon began his intrusions — Hare gave testimony to the Disclosure Project, a public initiative organized by Dr. Steven Greer to collect statements from military, intelligence, and government witnesses regarding UFO activity.
Hare testified that while working at JSC, she walked into a photo lab in Building 8 and saw a colleague working on a satellite image. The image showed a clear, defined object above the Earth. When she asked about it, the colleague told her it was his job to airbrush such objects out of images before they were released. He told her the process was routine.
Hare also described conversations with security guards who told her about a section of Building 8 that required higher clearance than she held — where, she was told, the raw satellite imagery was stored before processing. She was never allowed in.
McKinnon's claim is that he found his way into exactly this section — remotely, from London, through a blank admin password. What he described seeing — raw vs. processed image folders, high-resolution satellite photos with anomalous objects — is precisely consistent with what Donna Hare described from inside the building a decade earlier.
Donna Hare was not the only corroborating witness. Karl Wolf, a US Air Force Airman First Class with a Top Secret crypto clearance, also testified to the Disclosure Project. Wolf stated that in 1965, while working at the NSA facility at Langley Air Force Base processing data from the Lunar Orbiter project, a colleague showed him photographs of the far side of the Moon.
The photographs, according to Wolf, showed structures on the lunar surface — geometric shapes, towers, and what appeared to be constructed facilities. Wolf's colleague told him the discovery was being kept classified. Wolf maintained his account until his death in 2018.
These are not McKinnon's claims. These are independent testimonies from credentialed NASA and military personnel who described, before McKinnon ever touched a keyboard, the same pattern: imagery being captured, classified, and sanitized before public release.
The program McKinnon described — Solar Warden — was allegedly operated through an organization that actually exists: the United States Naval Network and Space Operations Command, or NNSOC. This is not speculation. NNSOC is a real command with a real mission.
NNSOC was established in 2002 (reorganized from the Naval Space Command, which had existed since 1983) and is headquartered at the Naval Support Facility Dahlgren in Virginia. Its official mission involves satellite communications, space surveillance, and information operations. It tracks objects in orbit. It manages the Navy's portion of the US Space Surveillance Network.
McKinnon's claim is not that NNSOC exists — that's public record. His claim is that NNSOC operates assets that are not publicly disclosed: a fleet of space-based vehicles, staffed by officers who appear in no public database, conducting operations that appear in no public budget.
The US government maintains classified programs funded through what is publicly referred to as the "black budget" — a portion of the defense and intelligence budget that is not itemized or disclosed to Congress in full. In fiscal year 2023, the total US intelligence budget was approximately $100 billion. A significant portion of that budget is unaccounted for in public records.
The existence of black budget programs is not disputed. The National Reconnaissance Office (NRO), which builds and operates spy satellites, was itself classified for 31 years — from its founding in 1961 until its existence was declassified in 1992. For three decades, the US government operated an entire space agency that the public did not know existed.
If it happened once, the question is not whether it could happen again. The question is whether it is happening now.
The easy response to McKinnon's claims is: he saw things on screens in the middle of the night while high and paranoid, and his memory cannot be trusted. But the case resists this dismissal for specific, documented reasons.
Gary McKinnon is alive. He lives in the UK. He was never imprisoned, never fined, never formally punished. He was, by his own account, a systems administrator who got curious, wrote a simple script, and stumbled onto something he was not supposed to see. The US government spent ten years and millions of dollars trying to extradite him. Then it was over.
McKinnon did not leak classified documents. He did not whistle-blow through channels. He did not release files to journalists. Everything he claims to have found — the officer list, the ship names, the unfiltered image — exists only in his memory and his testimony. He could not save the image. He did not download the spreadsheet. The 56K modem, the 4-bit color display, the real-time remote session — these were the tools of a man who was looking through a keyhole, not carrying files out the door.
The US government's response tells its own story. You don't pursue a man for a decade across international courts, threaten him with 70 years in prison, and call his actions the biggest military hack of all time — over blank passwords. Either McKinnon caused genuine damage to national security by stumbling through unsecured systems, or he saw something that made his extradition, containment, and silence worth ten years of legal effort.
The government has never said which one it was. They have never addressed his specific claims. They have never denied the existence of the spreadsheet, the image, or the program. They charged him with unauthorized access and property damage. They never charged him with lying.
