Turmoil in Libya: Major Industries Hit by Massive DDoS Attacks

Turmoil in Libya: Major Industries Hit by Massive DDoS Attacks

setembro 12, 2023 | NSFOCUS

I. Background

In August, NSFOCUS Global Threat Hunting System spotted an abnormal trend of DDoS attacks against Libya. NSFOCUS Security Labs sorted out the traffic changes of DDoS attacks in August and found that this attack may be related to the turmoil in Libya in August by comparing it with key events in Libya in August. The specific attack trend is as follows:

Figure 1 Trend of DDoS Attacks in Libya

  • August 6: The new chairman of the Libyan High Council of State was elected; the DDoS attacks against Libya spiked on August 2 and 5;
  • August 9: A meeting between Libya and India to discuss restoring relations between the two countries, when there was a clear upward trend in DDoS attacks against Libya;
  • August 14: An intense armed conflict in Tripoli, Libya’s capital, caused dozens of people to die, and Libya suffered sustained large-scale DDoS attacks from August 14 to 20.
  • August 21: The central bank divided by Libya’s civil war reunited, and the trend of DDoS attacks on Libya that day was relatively moderate.

According to observations, the trend of DDoS attacks is closely related to Libya’s complex political environment. Monitoring results show that Libya’s voting network has suffered multiple DDoS attacks, which may undermine voters’ trust in the electoral process and have a certain impact on the outcome of Libya’s presidential election. In this large-scale DDoS attack, the time point of real-world armed forces conflict basically coincides with the trend of DDoS attacks on the cyberspace battlefield. Monitoring revealed also that several government departments in Libya had suffered DDoS attacks, which may have affected the conflict situation to some extent.

II. Typical Attack Events

The DDoS attacks suffered by Libya are mainly carpet-bombing attacks. In this round of DDoS attacks, 97 Class C IP addresses were attacked by carpet-bombing DDoS attacks, including 64 Class C IP addresses in continuous IP segments – This IP segment involves key government infrastructure, education, financial services, the energy industry, and other important sectors, and the attacks are highly targeted.

The carpet-bombing DDoS attack differs from traditional attacks against a single target IP. Attackers use known general attack methods to launch small-traffic DDoS attacks on each IP in the IP segment, so as to exceed the bandwidth limit of access switches and thus affect user services in the entire IP segment. Since the attack traffic of a single IP will not trigger the cleaning threshold of the defense system, this attack method can increase the defense difficulty by escaping the traditional DDoS defense system.

III. Libya DDoS Attack Analysis

Victim IP Address Distribution

Generally, the geographical distribution of DDoS attacks is positively correlated with the local economic development level and population. In the reflective DDoS attacks against Libya, Tripoli, its capital, as an important political, cultural and economic center of Libya, accounts for more than 99% of the attacks, making it the region where DDoS attacks are most concentrated.

From August 1 to 26, NSFOCUS’s Global Threat Hunting System detected that 25,082 IP addresses/domain names in Libya were attacked by DDoS, accounting for 5.8% of the country’s total of 434,258 public network IP addresses in Libya.

Internet Service Provider Distribution of Victim IP Addresses

With the rapid development of digital technology, network attacks are becoming more and more intense and complex. Internet service providers (ISPs) face an increasing threat of DDoS attacks. In these attack events, the ISPs affected by reflective DDoS attacks in Libya are mainly LTT Autonomous System, accounting for more than 97%.

LTT (Libyan Telecommunication and Technology) is an important telecommunication operator in Libya, headquartered in Tripoli, the capital. As Libya’s national telecommunications company, LTT provides a variety of telecommunications services, including fixed-line telephone, mobile communication, Internet access and data services. It has built and maintained an extensive communications infrastructure throughout Libya to meet the communications needs of individuals, businesses and governments.

IV. Conclusion

As the digital era rapidly evolves, the landscape of cyber threats intensifies, giving rise to a myriad of new attack types. Among the various attack methods, DDoS attacks stand out, preferred by hackers for their potent combination of destructiveness and stealth. They’ve become a significant weapon in the realm of cyber warfare. In view of the large-scale DDoS attacks in Libya, we concluded as follows:

1. The attacks lasted a long time and affected a wide range of industries, potentially related to the unstable situation in Libya.

According to NSFOCUS’s Global Threat Hunting System, from August 1 to now, many important industries such as government, education, finance and energy in Libya have suffered DDoS attacks. It is obvious that this is a long-lasting and highly targeted DDoS attack activity, which is obviously related to the turbulent situation in Libya in August. The Global Threat Hunting System will continuously monitor the dynamic attacks.

2. Critical infrastructure remains the primary target of large-scale DDoS attacks, and oil companies should pay special attention.

In this large-scale DDoS attack activity, the attacker’s primary targets were national critical infrastructure, including government and administrative systems, financial services, energy supply systems, etc. Libya has the largest oil reserves in Africa, and several of its oil companies have suffered DDoS attacks. Should critical infrastructure fail, it would severely jeopardize the smooth operation of the national framework and could induce prolonged detrimental effects on socio-economic growth.
