Since the fall of Tripoli, reporters, researchers, and former employees of the Libyan Telecom and Technology company have been uncovering and sharing details about how the Libyan government surveilled and monitored internet and phone networks.
These reports demonstrate the depth of the relationship between foreign information technology companies and the Gaddafi regime, mirroring similar relationships with the repressive regimes of Tunsia , Egypt , Syria , and others in the Middle East.
In the case of Libya, it is now clear that prior to the rebellion, the regime emphasized surveillance and data gathering over filtering. With the onset of conflict, the Gaddafi regime scrambled to put in place filtering and blocking technologies, and employed outsiders to attack opposition sites and communications.
Former and current LTT staff speak
Libya was collecting massive quantities of data on both phone networks and internet usage. In August, The Wall Street Journal described  seeing surveillance equipment manufactured by Narus , a wholly owned subsidiary of Boeing, Inc. , and Amesys , part of French company Bull S.A. , in an abandoned security unit.
In recent conversations in Tripoli, sources who are current and former employees of Libya Telecom and Technology  (LTT) have described the efforts of the Gaddafi regime to ramp up surveillance in the weeks after the rebellion. The efforts were led out of an Internet monitoring center  run by the Interior Ministry in Tripoli, a center connected to Libyan security agencies. They describe recruitment of hackers from China and Eastern Europe to block key opposition sites and social media such as Facebook and YouTube, run phishing campaigns to steal Facebook passwords, and generate viruses to infect user computers and compromise data security. They also describe extensive efforts to eavesdrop on Skype, phone networks, and internet running through VSAT connections. This confirms earlier Global Voices reporting  that describes “cyber attacks on [Libyan] opposition websites coming from Serbia.”
A backdoor to Thuraya satellite phones?
In addition, the same individuals assert that the Libyan government was able to gain backdoor  access to voice and data on Thuraya  satellite phones sold in Tripoli through official providers . Thuraya, who are based in the United Arab Emirates, deny they granted the Libyan government a backdoor.
Libya’s General Post and Telecommunications Corporation is a shareholder in Thuraya, but the relationship between the company and the Gaddafi regime has not always been smooth. In 2006, Libya was accused  by Thuraya of jamming its mobile satellite communications. The jamming occurred over six months, and disrupted service in Libya and surrounding regions. In February 2011, Thuraya once again said  that they had “conclusive evidence” that Libya was jamming signals on its Thuraya-2 satellite network.
Ebrahim E. Ebrahim, Thuraya’s Vice-President for Corporate & Marketing Communications, referred to the February incident in an email interview and says, Thuraya’s network “was subjected to harmful and unlawful interference in Libya, which we have evidence to suggest was intentional,” but that the “alleged backdoor never existed, which is why our network was subjected to the intentional jamming.”
Thuraya and other satellite phones have been used by media and NGOs during protests in authoritarian countries with the hope of data security – an assumption that may be misplaced, given the sophisticated technology available to monitor telecommunications networks. Thuraya says there are around 3000 subscribers to its service in Libya – with a focus on rural access where cell networks do not reach.
In the weeks before the rebel attack on Tripoli, Gaddafi threatened death  to anyone using Thuraya phones not registered in Libya. This may suggest that unregistered Thuraya phones were perceived as a threat by the government.
Is the Libyan internet safe now?
Libya has been able to legally purchase internet technology since the end of international trade sanctions in 2003 and 2004, following Gaddafi's disavowal of a weapons of mass destruction program and reparations payments for the Lockerbie airplane bombing . By several accounts Libya invested in technology manufactured in North America, Europe, and China, used to monitor and capture data on both internet and telephone networks.
In interviews, current and former employees of Libya Telecom and Technology assert that the Chinese companies Huawei  and ZTE  provided Libya with software for content filtering and blocking. The core Libyan internet has been built using technology from global providers, such as Cisco, Nera Networks, Alcatel-Lucent, Siemens Ericcson, and Huawei and ZTE.
Surveillance of these networks accompanied by occasional filtering and blocking by the Gaddafi regime has been public knowledge for several years. The Open Network Initiative's study  from August 2009 asserts that Libya practiced selective filtering, but significant surveillance at both the personal level in internet cafes and other public access points.
Libyans under Gaddafi were very wary about both personal and electronic surveillance. Many bloggers stayed far away from politically sensitive material, or published their work pseudonymously or anonymously. Citizen media remained dispersed, with active bloggers meeting rarely and never in large groups. This practice, it seems, was wise. The return of internet to Libya after the fall of Tripoli has meant the end of censorship and surveillance, at least in its earlier form. However, many bloggers and activists using social media remain cautious about revealing their identity, what they write, and where they are.
Given Libya’s uncertain political future, personal and data security will likely remain a key concern for Libyan citizens for some time.
