Securing Your Organization Against Ransomware Attacks

Nigerian businesses continue to reap immense gains from deploying contemporary digital technologies in the design and execution of their processes. But these tools aren’t always insulated from potential sabotage. Malicious actors may find vulnerabilities in those technologies, and exploit such weaknesses to wreak havoc on the organizations that use them.

One way that cybercriminals do this is by targeting their victims with ransomware. Over the past decade, cyberattacks involving ransomware have grown in number, and have become more sophisticated. These attacks hit SMEs and large corporations, and even public sector agencies, and costs them tens of millions of naira.
If you are a business or an institution in Nigeria, you should be concerned about ransomware and the damage it could cause you.
Ransomware: A Brief Introduction
Ransomware is a program that blocks access to its victim’s files until the victim pays a ransom. Cybercriminals infect a target’s computer with it, aiming to extort a specific amount of money from that target in return for restored access, in a manner akin to a kidnap-for-ransom.
Typically, the perpetrator would send ransomware disguised as a harmless file to victims. If the target downloads or opens the file, it infects their system. The program may be spread through email attachments, malicious URLs, remote desktop protocol, and even malicious advertising.
Newer ransomware types can self-propagate across a network, potentially infecting every system used in an organization. They are capable of shutting down entire businesses.
Ransomware Attacks Are Fairly Common
Reports on the state of IT and the contemporary business environment reveal that ransomware attacks are fairly common across the globe. Not surprisingly, they are usually concentrated on businesses.
In 2020 alone, there were an estimated 304 million ransomware attacks worldwide. This was up 62% on the previous year. According to the Singapore Computer Emergency Response Team, there was “a seven-fold jump” in the number of reported ransomware incidents in the first half of 2020.
Some of that spike in activity was attributed to cyber criminals trying to exploit lapse IT security during the COVID-19 pandemic; their targets were predominantly remote workforces. However, these incidents have numbered in the hundreds of millions per year since 2016.
Nigerian organizations have been affected. A report by the Sophos Group, a UK-based security software and hardware security firm, revealed that 53% of the Nigerian businesses it surveyed had been victims of ransomware in 2019.
Of the businesses hit, about 38% of them admitted to paying the attackers to regain access to their files. However, the Sophos report indicated that these payments didn’t always result in the victims recovering all their resources.
A Few Well-Known Ransomware Attacks
In 2019 and 2020, many companies worldwide were targeted by ransomware called Ryuk. It is spread via malicious emails that contain dubious links or attachments. If successfully deployed on an organization’s computers, it can request a ransom of more than $300,000. As of January 2021, cybercriminals had reaped more than $150 million from Ryuk.
Three years before this, another ransomware, Petya, began infecting computers in several countries. It denied users access to their Operating Systems and demanded a $300 ransom from them. A later version did not unlock the infected system even after the ransom was paid.
The most infamous ransomware attack to date involved the WannaCry program, which infected more than 200,000 computers in over 150 countries. In May 2017, it spread across the world fairly rapidly, affecting both businesses and public institutions. The global cost of the attack is believed to have exceeded $4 billion.
Since the first known ransomware was created in 1989, several more have been designed and deployed, to devastating effect.
Organizations Incur Significant Costs from Ransomware Attacks
The cost of recovering from a ransomware attack has doubled in the past year. The cumulative global cost was well over $1 billion in 2020 alone.
Sophos says that these incidents cost mid-sized businesses an average of $133,000 annually. Some companies incurred several million dollars in recovery costs. In many cases, this expenditure racks up from multiple incidents.
The most hard-hit sectors included media, IT and telecoms, and energy/oil and gas utilities. The public sector was the least frequently targeted. Regardless, organizations in these domains have spent large amounts of money on damages inflicted by ransomware.
Unfortunately, many SMEs are unable to bear the financial weight of recovery. At least 1 in 5 of these businesses shut down within a year of suffering an attack. Bigger companies are better able to cope, but they too aren’t immune from the burden that such events bring.
How to Protect Your Organization Against Ransomware
The threat of a ransomware attack is ever-present. You will do well to prepare for an attempted strike against you.
Map your assets and note the degrees to which each one is vulnerable to an attack. Work with your IT team to prepare a resilience plan, complete with data backup, business continuity, and recovery strategies.
Also, ensure that the latest Operating Systems patches are applied when they become available, and update critical software as soon as is possible. Carry out penetration tests to determine where the weak points are, and fix them.
Adopt enhanced passwords and multi-factor authentication for staff at your organization. Train them to verify emails and other messages before engaging with them, and not to open websites unless they have a URL that begins with ‘HTTPS’ (Hypertext Transfer Protocol). The last ‘s’ is crucial; it indicates a secure site.

Report Reveals Half of 2025’s Compromised Passwords were Already Leaked

Kaspersky’s latest research reveals that the majority of compromised passwords not only violate password-safety guidelines but also remain unchanged for extended periods, which drastically reduces their security.

To provide users with access to more sophisticated and modern ways to log in, Kaspersky’s Password Manager has been enhanced with Passkey technology, enabling users to securely access their accounts while enjoying seamless cross-device synchronisation.
Although passwords still remain one of the major authentication methods, they no longer top the security charts. Often crafted by users themselves, passwords are heavily influenced by human factors, which makes them potentially vulnerable. Kaspersky experts analysed major password leaks from 2023 to 2025 and identified several recurring patterns:
- Users frequently append predictable elements like numbers, dates, and personal identifiers to their passwords. For example, 10% of passwords in datasets analysed contain a number resembling a date (from 1990 to 2025), 0.5% of all leaked passwords end with the number 2024, which is every 200th password!
- The most commonly occurring password combination is ‘12345’, which drastically reduces cryptographic strength and shortens the time required for brute-force attacks to succeed. Among other popular password components are the word ‘love’ and users’ names, as well as countries’ names which are also often included in passwords.
- Moreover, the majority of leaked passwords remain unchanged for years. In 2025, 54% of leaked passwords had already been part of prior data breaches, underscoring widespread reuse of outdated passwords. According to data analysis the average lifetime of the password found in these leaks is 3.5-4 years.
What makes Passkeys more secure?
All these findings highlight the critical vulnerability of password-based authentication when protocols for creation, management, and storage are not rigorously followed. In response to the growing need for robust security, the industry is increasingly shifting its focus toward next-generation solutions like Passkeys, which offer stronger protection against evolving threats.
Passkey technology is based on cryptographic keys and biometrics and is not subjected to threats like phishing or data leaks. A passkey is created for a particular account on a particular platform and is stored directly on the user’s device or in a password manager.
New Passkey feature in Kaspersky Password Manager
When a user registers on a platform that supports Passkey, the device creates a private key and shares a public key with the service. The private key is stored directly on the device, which is good from a security point of view, but complicates authorisation from other devices.
Now Passkeys can be created and stored directly in Kaspersky Password Manager, which allows users to not only sign in to supported services with a single tap, but also access Passkeys on all their devices owing to secure synchronisation.
“From our own experience, we’ve seen how constantly juggling logins and passwords for work, study and even leisure can erode both time and security. Kaspersky Password Manager has long streamlined this process with tools like our secure password generator and auto-fill functionality – ensuring users never sacrifice safety for speed.
In addition to that, we are happy to offer to our customers a new Passkey feature – an enhanced level of accounts protection which makes authentication even simpler and, most importantly, more secure,” comments Marina Titova, Vice President for Consumer Business at Kaspersky.
Passkey functionality is now available on all platforms in the latest version of Kaspersky Password Manager. To create a passkey in Kaspersky Password Manager, first update the app to the latest version and grant it all necessary permissions. Then, open the website where you want to create the passkey and simply follow the in-app guidance to register and save it.

UBA Wins Africa’s Bank of the Year for Third Time in Five Years

Africa’s Global Bank, United Bank for Africa (UBA) Plc, has once again, reaffirmed its leadership as one of the continent’s most innovative and resilient financial institutions, as the bank has, for the third time in five years, been named the African Bank of the year 2025 by the Banker.com.

UBA
UBA also won the Best Bank of the Year awards in nine of its 20 African subsidiaries, bringing its total awards this year to ten as UBA Benin, UBA Chad, UBA Republic of Congo (Congo-Brazzaville), UBA Liberia, UBA Mali, UBA Mozambique, UBA Senegal, UBA Sierra Leone, and UBA Zambia, all came out tops as the best banks in their respective countries, underscoring the bank’s strength across West, Central and Southern Africa and highlighting the depth of its Pan-African franchise.
The Banker.com, a leading global finance news publication published by the Financial Times of London, organises the annual Bank of the Year Awards, and this year’s edition was held at a grand ceremony at the Peninsula, London, on Wednesday.
The Chief Executive Officer, UBA UK, Deji Adeyelure, received the awards on behalf of the bank, representing the Group Managing Director/CEO, Oliver Alawuba, and was accompanied by the bank’s Head Business Development, Mark Ifashe, and Head, Financial Institutions, Shilpam Jha.
The Banker’s awards are widely regarded as the most respected and rigorous in the global banking industry, celebrating institutions that demonstrate outstanding performance, innovation and strategic execution.
In its remarks on UBA’s winnings, the banker.com said, “For the third time in five years, UBA Group has won the coveted Bank of the Year award for Africa. UBA Group time after time punches above its weight against its larger African rivals. The bank this year also takes home nine separate country awards (one more than it gained for its last continental win in 2024), equivalent to around a quarter of the awards for the continent, and more than any of its continent-wide rivals.”
Continuing, it said, “Perhaps even more impressive is the fact that the awards were won across a broad geographic spread, going to lenders based in the Economic Community of West African States (Benin, Liberia, Senegal, Sierra Leone, and former member Mali), the Central African Economic and Monetary Community (Chad, Republic of Congo) and the Southern African Development Community (Mozambique, Zambia). Its award wins were particularly notable in the highly competitive categories for Benin and Mozambique.”
The Banker also highlighted UBA’s strong financial performance and commitment to future growth. In 2024, the Group recorded a 46.8 per cent increase in assets and a 6.1 per cent rise in pre-tax profits in local currency terms, while continuing to invest significantly in talent and technology. West Africa remains UBA’s heartland, with operating revenue and profit increasing by 87 per cent and 89 per cent respectively in H1 2025.
The bank’s digital and innovation leadership was equally recognised. During the year under review, and launched its Advance Top-Up buy-now-pay-later feature on the *919# USSD platform, expanding financial access for customers, while the bank’s chatbot Leo continued its strong growth trajectory, with transaction volumes rising by 29 per cent year-on-year in H1 2025. Notably, in August, Leo became the first African banking chatbot to enable cross-border payments via the Pan-African Payment and Settlement System (PAPSS).
UBA’s Group Managing Director/Chief Executive Officer, Oliver Alawuba, while reacting to the achievement, said the recognition affirms the bank’s long-term strategy and customer-first philosophy.
“This honour reflects the strength of our Pan-African network, the trust of our customers, and the dedication of our people. Winning Africa’s Bank of the Year for the third time in five years is not by chance; it is a testament to disciplined execution, innovation, and a deep understanding of the markets we serve,” Alawuba said.
“Our nine country awards across diverse regions of Africa show that UBA is not just growing, but growing with impact. We remain committed to driving financial inclusion, supporting economic development, and deploying technology that makes banking simpler, faster, and more accessible to Africans everywhere,” he added.
United Bank for Africa is one of the largest employers in the financial sector on the African continent, with 25,000 employees group-wide and serving over 45 million customers globally. Operating in twenty African countries, the United Kingdom, the United States of America, France and the United Arab Emirates, UBA provides retail, commercial and institutional banking services, leading financial inclusion and implementing cutting-edge technology.

GenAI Adoption Among African workers Outpace Global Peers

Africa’s workforce is embracing artificial intelligence (AI) at a faster pace than global peers, but pressure is mounting for organisations to ramp up digital skills development as generative AI (GenAI) begins reshaping roles across industries.

This is according to PwC’s Global Workforce Hopes and Fears Survey 2025, which shows a continent ready for AI-enabled transformation, but facing a narrowing window to prepare, through skills development initiatives.
The survey, covering nearly 50 000 workers worldwide and 1 753 across South Africa, Algeria, Kenya, Morocco and Nigeria, finds that African employees are already integrating AI into daily operations.
Sixty-four percent of respondents in Africa used AI tools in the past year, compared to 54% globally, and the sentiment is overwhelmingly positive. While only 17% report using GenAI every day, confidence in its benefits is high: 76% believe GenAI improves work quality, and 72% expect AI-driven productivity gains within three years.
In SA, executives are even more bullish, as 91% say AI has already lifted both productivity and work quality — a signal that leadership is pushing harder toward AI-enabled ways of working, notes the survey.
However, this optimism is coupled with rising concern about future readiness. Only 35% of African workers believe their skills will still be relevant three years from now. With GenAI expected to affect nearly half of all job roles, PwC warns that the continent’s workforce risks falling behind unless organisations accelerate large-scale reskilling.
Despite the pressures, employees are not standing still. PwC notes that African workers outperform their global peers in proactive learning, recording 15% higher participation in skills-building and receiving 6% more support from managers. This indicates that both workers and immediate supervisors recognise the pace of AI adoption and are pushing to adapt.
PwC Africa people and organisation leader, Dr Dayalan Govender, says the moment calls for decisive leadership. Organisations, he argues, must integrate AI into workforce strategies, accelerate digital adoption, and expand upskilling programmes at scale.
“Africa’s workforce is optimistic and ready for change, but leaders must accelerate digital adoption and invest in future-ready skills to convert this optimism into sustainable growth,” he says.
Beyond the technology shift, the survey captures a workforce hungry for growth but constrained by financial pressure. Many employees are preparing to make career moves: 45% plan to request a raise, and another 45% aim for a promotion in the next year. Yet household financial stability remains strained, with only a third of respondents reporting any money left over for savings.
Still, Africa’s workplaces continue to show strong foundations of trust and purpose — elements PwC believes will be critical in navigating GenAI disruption. More than 55% of workers trust management, and two-thirds say their work feels meaningful, both above global averages.
With AI adoption rising and employees motivated to reinvent their careers, PwC warns that the coming years will determine whether Africa’s early optimism translates into long-term competitiveness as GenAI transforms the world of work.
The report calls for embedding AI into workforce strategies to bridge the gap between optimism and practical adoption, scaling upskilling initiatives to prepare for GenAI disruption, and fostering trust and psychological safety to retain talent and drive innovation.
“For employers, these findings are a stark reminder that they can and should do more to help workers understand, adopt, and embrace AI’s transformative power.
“Employers may need to pay special attention to entry-level workers, nearly a third of whom say they’re worried to a large or very large extent about AI’s impact on their future, even as they’re also curious (47%) and optimistic (38%) about its long-term societal effects,” notes the report.
