The telecommunications supplier for the African nation of Namibia suffered a big 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 menace of ransomware.
Final month, Telecom Namibia alerted prospects {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 said in a Dec. 16 statement.
“Initially, it appeared that no delicate data was compromised, however current analyses confirmed that some buyer knowledge was compromised,” he stated. “The menace was contained about three weeks in the past and additional assaults on our techniques and third events have been prevented, [but the exposed information] was leaked on the darkish net … after we refused to barter to pay any ransom that will have been demanded.”
Namibia just isn’t alone in turning into a goal for cyberattackers targeted on profiting off of compromised infrastructure techniques. In June, South Africa’s Nationwide Well being Laboratory Service (NHLS) suffered a ransomware attack that disrupted techniques, deleted backups, and took weeks for the government-run community of healthcare testing laboratories to get well. In July, Hunters Worldwide exfiltrated greater than 18GB of knowledge from the Kenyan Urban Roads Authority (KURA). The identical month, the Nigerian Laptop Emergency Response Group (ngCERT) warned that the Phobos RaaS group had targeted critical cloud services serving the country’s organizations, with no less than one profitable compromise.
Telecoms, Important Infrastructure within the Crosshairs
General, ransomware accounted for a 3rd of profitable assaults within the area, together with assaults on energy firm Eneo in Cameroon in January 2024 and industrial organizations in Egypt and South Africa all year long, in keeping with knowledge from Optimistic Applied sciences, a cybersecurity agency that operates within the area.
The telecommunications and manufacturing sectors have 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 similar to fast digital transformation, geopolitical tensions, and insufficient cybersecurity measures defending essential infrastructure,” he says. “The rising quantity of consumer knowledge and increasing digital networks make sectors like telecommunications notably enticing targets for cybercriminals in search of monetary acquire or partaking in cyber espionage.”
The development will proceed in 2025, as a result of the fast digitization throughout a number of industries continues to outpace implementation of cybersecurity measures, Lukatsky says. The consequence: a rising assault floor space that continues to be weak.
“Sectors similar to vitality, 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 seem like utilizing African organizations as testbeds for his or her newest assaults, according to an October 2024 report.
“The RaaS mannequin permits attackers to deal with high-value targets, similar to massive companies or essential infrastructure suppliers, the place the potential ransom payout is considerably increased,” Singh says. “Cyberattacks on essential infrastructure stay among the many most profitable for cybercriminals, as these techniques present important public providers, and their disruption may cause important societal and financial harm.”
As well as, ransomware teams will not be focusing on simply African companies and authorities businesses, but additionally these organizations’ third-party suppliers, Singh says. Distributing malicious variations of in style software program has grow to be a preferred approach to infect private and enterprise units within the area. A March 2024 assault focusing on members of a preferred Discord group, for instance, infected developers 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.
“Over time, menace actors have demonstrated a broad array of ways, strategies, and procedures, together with hijacking GitHub accounts, malicious Python packages, organising pretend Python infrastructures, and using refined social engineering methods,” Singh provides.
African organizations must work to enhance the cyber consciousness of their workers and prospects and set up safe practices whereas pursuing digitization, he recommends. The dangers posed by cyberattacks will seemingly solely improve, because the geopolitical tensions rise within the area and worldwide, in keeping with Singh.
“Whereas Africa is probably not a first-rate goal in comparison with different continents,” he says, “many geopolitical elements can affect cyber menace actions, notably when state-sponsored actors are concerned.”
