Sophos Identifies Top Ransomware Families in Africa

Cyber security vendor Sophos has identified the top ransomware families that affected Africa in 2017.
According to Sophos, the Ceber ransomware accounted for 80% of attacks in Africa, followed by WannaCry (17%), and others like Jaff (1%), Locky (1%) and Petya (0.5%).
One of the most active kinds of ransomware out there, Cerber encrypts the files of infected users and demands money in exchange for enabling access to their files. It works even if a user is not connected to the Internet, so they can’t stop it by unplugging their PC.
Cerber, sold as a ransomware kit on the Dark Web, remains a dangerous threat, says Sophos, adding the creators of Cerber continuously update the code and charge a percentage of the ransom that the “middle-men” attackers receive from victims.
Regular new features make Cerber not only an effective attack tool, but perennially available to cyber criminals, the cyber security firm notes.
“This Dark Web business model is unfortunately working and, similar to a legitimate company, is likely funding the ongoing development of Cerber. We can assume the profits are motivating the authors to maintain the code,” says Dorka Palotay, SophosLabs security researcher and contributor to the ransomware analysis in the SophosLabs 2018 Malware Forecast.
The WannaCry ransomware attack was a May 2017 worldwide cyber attack by the WannaCry ransomware cryptoworm, which targeted computers running the Microsoft Windows operating system by encrypting data and demanding ransom payments in the Bitcoin crypto-currency.
“Looking at the whole world, WannaCry was responsible for 45.3% of the ransomware attacks, while in Africa this value is only 17%,” Palotay says.
“In Africa, clearly Cerber was the biggest ransomware threat this year, since 80% of the ransomware lookups was caused by Cerber, while this number is only 44.2% if we look at the whole world. Regarding the smaller families, the results are very similar.”
The SophosLabs 2018 Malware Forecast report recaps ransomware and other cyber security trends based on data collected from Sophos customer computers worldwide from 1 April to 3 October 2017.
One key finding shows that while ransomware predominately attacked Windows systems in the last six months, Android, Linux and MacOS platforms were not immune.
“Ransomware has become platform-agnostic. Ransomware mostly targets Windows computers, but this year, SophosLabs saw an increased amount of crypto-attacks on different devices and operating systems used by our customers worldwide,” says Palotay.
She notes that for the first time Sophos saw ransomware with worm-like characteristics, which contributed to the rapid expansion of WannaCry.
“This ransomware took advantage of a known Windows vulnerability to infect and spread to computers, making it hard to control.
“Even though our customers are protected against it and WannaCry has tapered off, we still see the threat because of its inherent nature to keep scanning and attacking computers. We’re expecting cyber criminals to build upon this ability to replicate as seen in WannaCry and NotPetya, and this is already evident with Bad Rabbit ransomware, which shows many similarities to NotPetya.”

Nigeria @ Risks Losing Digital Control- NiRA

Nigeria is at risks losing digital control of its cyberspace following the alarming surge in cyberattacks in the country.

The surge show a dangerous shift from opportunistic cybercrime, facing approximately 4,710 threats weekly and ranking as a top target for cybercriminals in Africa.
Nigeria Internet Registration Association (NiRA) recently warned that the trend weakens the country’s control over its digital identity and limits economic gains from its expanding online ecosystem.
Speaking at the .ng Media Advocacy and Capacity Building Initiative for the Nigerian Information Technology Reporters Association (NITRA), organised by NiRA in Lagos, Adesola Akinsanya, president, NiRA, questioned who truly owns Nigeria’s digital presence, stressing that the answer lies in deliberate choices regarding domain name adoption and the narratives shaping the country’s digital ecosystem.
He likened the widespread adoption of foreign domains to building assets on land owned by others, where control, legal authority, and economic benefits ultimately reside outside the country.
According to him, many Nigerian businesses operating on domains such as .com are effectively anchoring their digital operations on infrastructure beyond national control.
Industry stakeholders at the event noted that while Nigeria’s digital economy continues to expand driven by increasing internet penetration and a vibrant tech ecosystem a significant portion of the value generated is lost through payments tied to foreign domain registration and hosting services.
Seyi Onasanya, chief operating officer, NiRA, described domain names as “digital real estate,” emphasizing their role as a foundational layer of the modern economy.
She stated that countries that prioritise local domain systems are better positioned to retain value, strengthen trust, and enhance digital competitiveness.
Onasanya added that although country-code domains account for nearly 40 percent of global domain registrations, Nigeria still records relatively low adoption of its .ng domain despite its large population and millions of small and medium enterprises.
Experts at the forum warned that dependence on foreign domains contributes to capital flight, weakens national branding, and exposes businesses to external regulatory risks.
They stressed that every domain name represents a potential economic asset linked to transactions, jobs, and overall GDP growth.
Beyond economic implications, speakers highlighted trust and security as critical issues.
Ridwan Badmus, legal and cybersecurity expert, noted that Nigeria’s regulatory framework is evolving to support a more secure digital environment, including policies encouraging government institutions to adopt local domains and hosting services.
He explained that the .ng domain benefits from enhanced security features such as DNS Security Extensions (DNSSEC) and improved monitoring systems, which strengthen resilience against cyber threats.

CIBN Allegedly Hit by 250GB Data Breach

Chartered Institute of Bankers of Nigeria (CIBN), the country’s apex professional body for bankers, is reportedly at the centre of a major cybersecurity incident following claims that its internal database estimated at about 250GB has been compromised and leaked online by an unidentified threat actor, according to the Guardian.

The alleged breach, which surfaced recently on underground cybercrime forums, is said to involve a wide range of sensitive institutional and personal data belonging to members of the banking profession.
According to preliminary assessments of sample files circulating online, the exposed information reportedly includes full names, email addresses, phone numbers, residential and business addresses, membership records, scanned identification documents, certificates, and even internal source codes linked to digital systems.
While the authenticity of the full dataset has not been independently verified, cybersecurity observers note that the scale of the alleged leak is consistent with a growing pattern of attacks targeting financial institutions and professional bodies across Nigeria’s banking ecosystem.
Chartered Institute of Bankers of Nigeria, established in the early 1960s and chartered to regulate banking professionalism in the country, plays a central role in setting ethical and educational standards for bankers nationwide.
It counts major financial institutions, including the Central Bank of Nigeria and commercial banks, among its corporate members.
In recent years, the institute has itself acknowledged rising cyber risks affecting the financial sector, warning that banks and related institutions face increasing exposure to digital attacks, including website hijacking, ransomware threats, and data breaches targeting sensitive financial information.
This latest allegation adds to a series of reported cyber incidents involving Nigerian financial institutions, where attackers have increasingly focused on exploiting personal data for identity theft and phishing schemes.
Cybersecurity analysts say Nigeria has witnessed a broader surge in data breaches across banking, telecoms, and government systems, with millions of records reportedly circulating on the dark web in recent years.
The alleged CIBN breach, if confirmed, would further highlight vulnerabilities in institutional data protection frameworks and the growing sophistication of cybercriminal operations targeting financial ecosystems.
However, CIBN has not issued an official confirmation or denial regarding the alleged breach.
But, the need for immediate forensic investigation, member notification protocols, and a comprehensive audit of the institute’s digital infrastructure cannot be overlooked.
Authorities and data protection regulators are also expected to assess the claims as part of broader efforts to curb escalating cyber threats within Nigeria’s financial services sector.
