Introduction
Gary McKinnon’s alleged hacking campaign was not confined to a single military installation. According to United States indictments and later UK court records, prosecutors treated the intrusions between 2001 and 2002 as one connected campaign that reached across multiple branches of the US armed forces, the Pentagon and NASA. Rather than alleging a single spectacular breach, the case described repeated unauthorised access to vulnerable Windows systems that allowed movement from one compromised network to another. This broader pattern explains why the case became notable not only for McKinnon’s claimed interest in UFO-related material, but also for the geographical and organisational spread of the affected government networks.[Department of Justice]justice.govDepartment of JusticeLondon, England Hacker Indicted Under Computer Fraud and Abuse Act For Accessing Military Computers (November 12, 20…
Military Branches Named in the Indictments
The most detailed judicial summary of the allegations appears in the House of Lords judgment concerning McKinnon’s extradition. It states that prosecutors alleged he accessed 97 US government computers consisting of:
- 53 US Army computers
- 26 US Navy computers
- 16 NASA computers
- 1 Department of Defense computer
- 1 US Air Force computer
These figures illustrate that the investigation was never limited to a single service branch. Instead, prosecutors argued that the intrusions crossed organisational boundaries within the US defence establishment while following a broadly similar technical pattern of identifying poorly secured Windows systems and obtaining administrative access.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and Another…
The US Department of Justice’s Virginia indictment described a closely related but slightly different charging framework, alleging unauthorised access to 92 military and NASA computers, together with six private-sector computers. The differing totals reflect the way separate indictments grouped offences rather than evidence of different underlying campaigns.[Department of Justice]justice.govDepartment of JusticeLondon, England Hacker Indicted Under Computer Fraud and Abuse Act For Accessing Military Computers (November 12, 20…
NASA and Pentagon Systems in the Record
NASA occupied a significant place in the prosecution’s allegations because McKinnon was accused of accessing 16 NASA computers. The indictments, however, primarily focused on the alleged unauthorised access, installation of remote-control software, copying of files and passwords, and resulting system damage rather than on the content of files he viewed. Official charging documents did not endorse or verify McKinnon’s later public claims about discovering evidence relating to UFOs or secret space programmes.[Department of Justice]justice.govDepartment of JusticeLondon, England Hacker Indicted Under Computer Fraud and Abuse Act For Accessing Military Computers (November 12, 20…
The Department of Justice also alleged that the campaign reached computers at the Pentagon, including two Pentagon systems identified in the Virginia indictment. Together with Army, Navy and Air Force systems, these allegations reinforced the government’s argument that the intrusions affected networks supporting national defence rather than isolated administrative computers.[Department of Justice]justice.govDepartment of JusticeBritish National Charged with Hacking Into N.J. Naval Weapons Station Computers, Disabling Network After Sept. 11 (N…
How Separate Intrusions Formed One Campaign
Rather than portraying each incident as independent, investigators argued that McKinnon used compromised computers as stepping stones into additional government networks.
According to the House of Lords judgment, prosecutors alleged that he:
- identified internet-connected Microsoft Windows systems;
- extracted administrator account details and passwords;
- installed the commercial remote-access program RemotelyAnywhere;
- added further software to assist additional compromises and conceal activity; and
- used already-compromised computers to scan for further vulnerable government systems.
The judgment states that this approach enabled scans of more than 73,000 US government computers in search of additional vulnerable hosts. The campaign’s scale therefore came less from a single sophisticated exploit than from repeatedly finding similar weaknesses across multiple organisations.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and Another…
The Department of Justice similarly alleged that, once inside one network, McKinnon used that position to locate additional military and NASA systems, creating a chain of intrusions spanning multiple jurisdictions.[Department of Justice]justice.govDepartment of JusticeLondon, England Hacker Indicted Under Computer Fraud and Abuse Act For Accessing Military Computers (November 12, 20…
Geographic Reach Across the United States
The alleged campaign extended beyond one military base or state. Court records and indictments identify systems located in several parts of the United States, including:
- Army computers in Virginia and Washington, DC, supporting the Military District of Washington.
- Naval systems at Naval Weapons Station Earle, New Jersey.
- Pentagon computers in the Washington area.
- NASA computers distributed across the agency’s network infrastructure.
The New Jersey indictment concentrated specifically on the Naval Weapons Station Earle allegations, while the Virginia indictment covered the broader collection of Army, Navy, Air Force, Pentagon and NASA systems. Together they presented the alleged activity as one sustained course of conduct prosecuted through separate federal jurisdictions.[Department of Justice]justice.govDepartment of JusticeBritish National Charged with Hacking Into N.J. Naval Weapons Station Computers, Disabling Network After Sept. 11 (N…
Why Prosecutors Viewed It as a Single Operation
The government’s case relied less on the individual importance of each compromised computer than on the cumulative pattern. Prosecutors argued that the repeated installation of remote-access software, copying of password files, deletion of system files and movement between networks demonstrated an ongoing campaign rather than isolated exploratory logins. They also alleged that disruptions affected the Military District of Washington network and Naval Weapons Station Earle, while estimating losses approaching US$900,000 across military organisations, NASA and affected private companies.[Department of Justice]justice.govDepartment of JusticeLondon, England Hacker Indicted Under Computer Fraud and Abuse Act For Accessing Military Computers (November 12, 20…
McKinnon accepted that he had gained unauthorised access but consistently disputed the prosecution’s portrayal of his intent. He maintained that his purpose was to search government systems for evidence relating to UFOs and advanced technology, whereas the indictments framed the activity as criminal unauthorised access causing damage to defence and government computer systems. Because extradition was ultimately blocked and no US trial took place, these competing accounts were never tested before an American jury.[UK Parliament]publications.parliament.ukUK Parliament House of LordsUK ParliamentHouse of Lords - Mckinnon V Government of The United States of America and Another…
