Nigeria, Others See a Decrease of Ordinary Threats, Experience Increase of Targeted Malware
According to Kaspersky’s latest research on the threat landscape trends, South Africa, Kenya and Nigeria are facing a dramatic change in the threat landscape.
While regular, self-propagating malware is decreasing dramatically, as it is no longer effective and cannot fly under security radars, the region will see the growth of new cybercrime models in the upcoming year.
While comparing the overall number of mass cyberattacks in 2021, security researchers at Kaspersky noticed a 7.5% decrease in Nigeria, 12% decrease in South Africa and an unprecedented 28.6% decrease in Kenya.
The reason for such a change was the introduction and popularisation of new cybercrime models in the region, with cybercrime tools becoming more targeted along with a long running trend where malware creators rely not on the technical advantage of their technologies over security protection, but on the human factor.
This has stimulated the evolution of phishing schemes in 2021. In particular, the region saw a wave of ‘Anomalous’ spyware attacks.
The usual phishing spyware attack begins when attackers infect a victim by sending them an e-mail with a malicious attachment or a link to a compromised website and ends when the spyware is downloaded and activated on the victim’s device.
Having gathered all necessary data, the operator usually ends the operation by attempting to leave the infected system unnoticed.
In the anomalous attacks, however, the victim’s device becomes not only a source of data but also a tool for spyware distribution.
Having access to the victim’s email server, the malware operators use it to send phishing emails from a legitimate company’s email address. In this case, anomalous spyware attacks an organisation’s server for collecting stolen data from another organisation and sending further phishing emails.
“The Anomalous spyware attacks have a huge potential for growth in South Africa, Kenya and Nigeria in 2022, because unlike regular spyware the entry level for attackers who wish to employ this tactic is significantly lower – since instead of paying for their own infrastructure, they abuse and employ the victims’ resources.
We see that cheaper attack methods have always been on the rise in the region and cybercriminals quickly pick up on new tactics. Kaspersky therefore suggests that in the nearest future, these countries should be prepared for such attacks”, says Maria Garnaeva, Senior Security Researcher at Kaspersky ICS CERT team.
However, the mass scale attacks are not disappearing, but rather transforming. Garnaeva also reports on a mass-scale and pervasive fake installers campaigns, where fake pirated software sites serve up malware as a service.
The scheme is usually the following: a user searches for a free version of an extremely popular legitimate spyware. The cybercriminals are offering them a fake installer using ‘black SEO technic’ – the abuse of the legitimate search engines, resulting in the offering of the fraudulent websites first. As a result of software installer execution, a few dozen malware samples are downloaded and installed with a goal of turning the infected devices into a part of the Glupteba botnet.
The whole fake installers campaign and botnet has been extremely active in South Africa in 2021 and continues to evolve, yet it is scarcely researched.
“While the Glupteba botnet seems to be a threat for consumers, we are still researching it and keeping an eye on its behaviour, since some distributed malware resembles APT-related samples like Lazarus APT groups and were recently used in the largest DDoS attack in Russia.
It is too early to say it with a high level of confidence, but these factors may suggest that we are now entering the era where APT actors start to use existing malware distribution platforms which makes an attribution of such attacks harder and opens a new vector similar to supply chain attacks,” adds Garnaeva.
In order to stay protected from such new cybercrime models and threats, Kaspersky recommends the following:
- Pay close attention to and don’t open any suspicious files or attachments received from unknown sources.
- Do not download and install applications from untrusted sources.
- Do not click on any links received from unknown sources and suspicious online advertisements.
- Create strong passwords and don’t forget to change them regularly.
- Always install updates. Some of them may contain critical security issues fixes.
- Ignore messages asking to disable security systems for office software or antivirus software.
- Use a robust security solution appropriate to your system type and devices, such as Kaspersky Internet Security
Kaspersky’s Global Research and Analysis Team (GReAT) experts at the 10th annual Cyber Security Weekend – META 2025 held recently, talked about supply chain attacks and reported that by the end of 2024 a total of 14,000 malicious packages were found in open-source projects, a 48% increase compared to the end of 2023. 42 million versions of open-source packages have been examined by Kaspersky throughout 2024 in search for vulnerabilities.
Open-source is software with source code that anyone can inspect, modify, and enhance. Popular open-source packages include GoMod, Maven, NuGet, npm, PyPI, and others.
These are tools that power countless applications and help developers easily find, install, and manage pre-built code libraries, making it simpler to build software by reusing code others have written. Attackers take advantage of the popularity of these and other packages.
In March 2025, the Lazarus Group was reported to have deployed several malicious npm packages, which were downloaded multiple times before removal. These packages contained malware to steal credentials, cryptocurrency wallet data, and deploy backdoors, targeting developers’ systems across Windows, macOS, and Linux.
The attack leveraged GitHub repositories for added legitimacy, highlighting the group’s sophisticated supply chain tactics. Kaspersky’s GReAT also found other npm packages related to this attack. Malicious npm packages could have been integrated into web development, cryptocurrency platforms, and enterprise software, risking widespread data theft and financial losses.
In 2024, a sophisticated backdoor was discovered in XZ Utils versions 5.6.0 and 5.6.1, a widely used compression library in Linux distributions. Inserted by a trusted contributor, the malicious code targeted SSH servers, enabling remote command execution and threatening countless systems globally.
Detected before widespread exploitation due to performance anomalies, the incident highlighted the dangers of supply chain attacks. XZ Utils is integral to operating systems, cloud servers, and IoT devices, making its compromise a threat to critical infrastructure and enterprise networks.
In 2024, Kaspersky’s GReAT discovered that attackers uploaded malicious Python packages like chatgpt-python and chatgpt-wrapper to PyPI, mimicking legitimate tools for interacting with ChatGPT APIs.
These packages, designed to steal credentials and deploy backdoors, capitalised on the popularity of AI development to trick developers into downloading them. These packages could have been used in AI development, chatbot integrations, and data analytics platforms, endangering sensitive AI workflows and user data.
“Open-source software is the backbone of many modern solutions, but its openness is being weaponised. The 50% rise in malicious packages by the end of 2024 shows attackers are actively embedding sophisticated backdoors and data stealers in popular packages, which millions rely on.
“Without rigorous vetting and real-time monitoring, a single compromised package can trigger a global breach. Organisations need to secure the supply chain before the next XZ Utils-level attack succeeds,” comments Dmitry Galov, Head of Research Center for Russia and CIS at Kaspersky’s Global Research and Analysis Team.
Nigeria Data Protection Commission (NDPC) has launched an investigation into allegations that the confidentiality and integrity of candidates’ personal data may have been compromised by hackers.
The Commission initiated the inquiry following concerns over possible data breaches during examinations.
Preliminary findings indicate that several examination centres may not have implemented adequate technical and organizational measures to safeguard candidates’ personal information, as required under data protection regulations.
Although the incident reportedly affected 379, 997 candidates, the NDPC’s investigation is poised to cover a systemic audit of data processing and third parties.
It will be recalled that JAMB recently admitted that a technical error on its platform affected a total of 379,997 candidates in 157 examination centres across Lagos and the South-East.
Further investigation led to the arrest of at least 20 suspects who are currently in the custody of the Department of State Services and the Nigerian Police Force.
Cyber security firm, Kaspersky, has once again warned that sophisticated cybercriminals increasingly target Africa as ransomware and advanced persistent threats (APTs) escalate across the region.
Speaking at the company’s annual Cyber Security Weekend for the Middle East, Turkiye and Africa (META) region, the cybersecurity firm’s Global Research and Analysis Team highlighted growing digital threats affecting African nations.
Kenya, Nigeria, and South Africa emerged as hotspots, with Kenya recording one of the highest web threat incident rates at 20.1% in first quarter 2025.
“While ransomware is less prevalent in Africa due to lower levels of digitisation and economic constraints, countries like South Africa and Nigeria are seeing a sharp rise in attacks,” said Sergey Lozhkin, head of META and APAC regions at Kaspersky.
Kaspersky noted a 0.01 percentage point increase in African ransomware cases year-on-year, reaching 0.41%, still below global and Middle Eastern averages, but a troubling sign for the continent’s emerging digital infrastructure.
Experts warned that attackers are refining their tactics, shifting focus to unconventional entry points like IoT devices, smart appliances, and misconfigured hardware.
“As these economies expand digitally, sectors such as manufacturing, finance and government are becoming key targets,” said Lozhkin
The cyber-crime landscape is evolving quickly, fuelled by AI tools and dark web access to large language models, which enable less skilled actors to launch convincing phishing and malware campaigns.
Groups like FunkSec, which uses AI-generated code and a low-cost ransom model, are redefining ransomware operations.
“African organisations face the dual challenge of expanding digital footprints and limited cybersecurity awareness. This makes layered defense strategies, including network segmentation, real-time monitoring and regular staff training, essential,” stated Lozhkin
Kaspersky continues to monitor 25 active APT groups in the META region, including SideWinder and MuddyWater, some of which are known to target African institutions.
To bolster defenses, the firm recommends using tools such as its free Anti-Ransomware Tool for Business and the Kaspersky Next suite for threat visibility and response.
