The telecommunications supplier for the African nation of Namibia suffered a major ransomware assault late final yr, turning into a visual image of the merging of two developments within the area: rising assaults on essential infrastructure and the rising risk of ransomware.
Final month, Telecom Namibia alerted clients {that a} profitable assault by the ransomware-as-a-service (RaaS) group Hunters Worldwide led to customers’ data being leaked on-line. The corporate is working with regulation enforcement businesses and third-party incident responders to uncover extra particulars, CEO Stanley Shanapinda mentioned in a Dec. 16 assertion.
“Initially, it appeared that no delicate data was compromised, however latest analyses confirmed that some buyer knowledge was compromised,” he mentioned. “The risk was contained about three weeks in the past and additional assaults on our methods and third events had been prevented, [but the exposed information] was leaked on the darkish net … after we refused to barter to pay any ransom which will have been demanded.”
Namibia shouldn’t be alone in turning into a goal for cyberattackers targeted on profiting off of compromised infrastructure methods. In June, South Africa’s Nationwide Well being Laboratory Service (NHLS) suffered a ransomware assault that disrupted methods, deleted backups, and took weeks for the government-run community of healthcare testing laboratories to recuperate. In July, Hunters Worldwide exfiltrated greater than 18GB of information from the Kenyan City Roads Authority (KURA). The identical month, the Nigerian Laptop Emergency Response Crew (ngCERT) warned that the Phobos RaaS group had focused essential cloud companies serving the nation’s organizations, with at the least one profitable compromise.
Telecoms, Important Infrastructure within the Crosshairs
Total, ransomware accounted for a 3rd of profitable assaults within the area, together with assaults on power agency Eneo in Cameroon in January 2024 and industrial organizations in Egypt and South Africa all year long, in response to knowledge from Optimistic Applied sciences, a cybersecurity agency that operates within the area.
The telecommunications and manufacturing sectors had been additionally closely focused, with every sector accounting for 10% of profitable assaults, says Alexey Lukatsky, managing director and cybersecurity enterprise guide at Optimistic Applied sciences.
“These assaults are pushed by elements equivalent to speedy digital transformation, geopolitical tensions, and insufficient cybersecurity measures defending essential infrastructure,” he says. “The rising quantity of person knowledge and increasing digital networks make sectors like telecommunications significantly engaging targets for cybercriminals looking for monetary acquire or partaking in cyber espionage.”
The development will proceed in 2025, as a result of the speedy digitization throughout a number of industries continues to outpace implementation of cybersecurity measures, Lukatsky says. The outcome: a rising assault floor space that is still susceptible.
“Sectors equivalent to power, telecommunications, and manufacturing will proceed to be prime targets for cybercriminals and APT teams, motivated by monetary acquire, knowledge theft, or geopolitical aims,” he says.
The Age of RaaS
The rise of ransomware-as-a-service choices has additionally accelerated assaults on essential infrastructure, says Avinash Singh, a pc science lecturer and head of the Clever Cyber Forensics Lab on the College of Pretoria in South Africa. RaaS has taken off in Africa, partly as a result of some ransomware gangs look like utilizing African organizations as testbeds for his or her newest assaults, in response to an October 2024 report.
“The RaaS mannequin permits attackers to deal with high-value targets, equivalent to giant companies or essential infrastructure suppliers, the place the potential ransom payout is considerably greater,” Singh says. “Cyberattacks on essential infrastructure stay among the many most profitable for cybercriminals, as these methods present important public companies, and their disruption could cause important societal and financial injury.”
As well as, ransomware teams usually are not focusing on simply African companies and authorities businesses, but additionally these organizations’ third-party suppliers, Singh says. Distributing malicious variations of well-liked software program has turn out to be a well-liked technique to infect private and enterprise units within the area. A March 2024 assault focusing on members of a well-liked Discord neighborhood, for instance, contaminated builders with information-stealing malware by compromising a developer’s account and poisoning the repository.
Lots of the threats affecting African builders are the identical as these affecting the worldwide cyber panorama, he says.
“Through the years, risk actors have demonstrated a broad array of ways, strategies, and procedures, together with hijacking GitHub accounts, malicious Python packages, establishing faux Python infrastructures, and using refined social engineering methods,” Singh provides.
African organizations have to work to enhance the cyber consciousness of their workers and clients and set up safe practices whereas pursuing digitization, he recommends. The dangers posed by cyberattacks will probably solely enhance, because the geopolitical tensions rise within the area and worldwide, in response to Singh.
“Whereas Africa will not be a main goal in comparison with different continents,” he says, “many geopolitical elements can affect cyber risk actions, significantly when state-sponsored actors are concerned.”
