Last year, hackers didn’t just hack — they also collected billion-account databases from breaches and leaks that had occurred years ago, only to sell them for profit.

Biggest, Worst Personal Data Leaks of 2019

However, eight breaches were really shocking and affected millions of people worldwide, according to https://nordpass.com

“With so many breaches and leaks in 2019, it’s possible that your email address or other details ended up in the wrong hands. You can check whether your email was in one of the databases by going to Have I Been Pwned,” said Daniel Markuson, a digital privacy expert at NordVPN.

“You can also check whether your password has leaked and might be used in a credential stuffing attack by visiting NordPass and checking if your password is secure.”

American Medical Collection Agency (11.9 million + 7.7 million). This breach affected not one but two lab testing companies.

First, Quest Diagnostics was notified that someone had unauthorized access to AMCA’s databases for eight months.

The hack affected almost 12 million of their customers. Hackers got access to very personal information such as credit card numbers, bank account information, medical information, and Social Security numbers.

Then there was LabCorp, another company whose customers were affected by this breach. Almost 8 million customers’ personal and financial data was compromised.

Suprema (27.8 million). This security loophole left 27.8 million people’s biometric data exposed. Suprema is a security company responsible for the web-based Biostar 2 biometrics lock system.

The system is used by almost 6,000 organizations in 83 countries, including governments and banks. Biostar uses fingerprints and facial recognition to allow employees into restricted buildings and areas.

Security researchers from VPNmentor found that the Biostar database was left unprotected and largely unencrypted. Worst of all, they got access to tons of sensitive information.

Houzz (48.9 million). Houzz, a home design website, started the year announcing a breach in which hackers got unauthorized access to its customers’ publicly available information, as well as usernames and encrypted passwords.

The company noticed the breach at the end of 2018 and was pretty vague about it in their public statements. However, ITRC reported that the hack affected almost 49 million Houzz customers.

Capital One (106 million). In July, Capital One announced that they suffered a massive data breach affecting 100 million Americans and 6 million Canadians.

The hacker accessed credit card applications made between 2005 and 2019. They contained personal data including names, home addresses, email addresses, dates of birth, etc.

What makes this one of the worst breaches of 2019 is that some bank numbers and social security numbers also ended up in the hands of the hacker.

Zynga (218 million). If you’ve ever played online games such as “Words with Friends” or “Draw Something,” you should be worried because their creator, Zynga, was breached in 2019.

The hack affected a whopping 218 million users. Bad actors accessed log-in credentials, usernames, email addresses, some Facebook IDs, some phone numbers, and Zynga account IDs.

Facebook (419 million). A security researcher at the GDI Foundation found an unprotected server with a database containing approximately 419 million phone numbers belonging to Facebook users.

The database was available to anyone, and it also included Facebook IDs, which makes finding user’s names and personal details even easier.

The owner of the server wasn’t found, but the database was taken down shortly after it was discovered.

Collection by Gnosticplayers (1 billion+). This isn’t a breach per se as much as it is a collection of breaches affecting more than 1 billion internet users.

A hacker who calls himself Gnosticplayers collected databases from 45 companies and put them up for sale on the dark web.

These batches contained data such as users’ full names, email addresses, passwords, location data, and social media account information.

The companies whose data was released includes Dubsmash (162 million), MyFitnessPal (151 million), MyHeritage (92 million), ShareThis (41 million), Animoto (25 million), 500px (15 million), CoffeeMeetsBagel (6 million), and more.

Collections #1-5 (3 billion). Collections #1-5 were probably the biggest leaks of 2019. They contained usernames and passwords collected over many years of breaches.

These batches appeared on hacking forums and were noticed by security researcher Troy Hunt, who identified the link between them all and informed the public.

The first batch was released in January and contained the data of 770 million people. Then, a few weeks later, Collections #2-5 appeared on the internet.

They contained 25 billion unique records and roughly 2.2 billion unique usernames and passwords, making this one of the most significant leaks to date.

GenAI Adoption Among African workers Outpace Global Peers

Published

on

Kindly share this post

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.

Nigeria Records Highest Weekly Cyberattacks in Africa — Report

Nigerian organisations are facing the highest volume of weekly cyberattacks in Africa, according to the newly released African Perspectives on Cyber Security Report 2025 by Check Point Software Technologies Ltd., a global leader in cybersecurity solutions.

Nigeria Records Highest Weekly Cyberattacks in Africa — Report

The report revealed that Nigerian firms experience an average of 4,200 attacks per week, significantly higher than the continental average of 3,153 and 60 per cent above the global average of 1,963 attacks per organisation.

The findings highlight a sharp rise in attacks across Africa, driven largely by artificial intelligence-enabled threats.

Kingsley Oseghale, country manager for West Africa at Check Point, said attackers are increasingly using AI to automate phishing, impersonation, and cloud exploitation.

“AI has become part of the attack surface,” Oseghale said. “Attackers are using it to automate phishing and identity theft at scale. The only effective response is prevention-first security that combines visibility, governance, and AI protection.”

The report noted that cybercriminals are exploiting exposed identities and misconfigured systems to target critical sectors, including finance, energy, telecoms, and government.

Identity-led intrusions, AI-generated phishing campaigns, and multi-vector ransomware are on the rise.

Across the continent, Check Point identified key trends in different markets. Nigeria is experiencing business email compromise and cloud exploitation; South Africa faces rising ransomware, smishing, and botnet infections such as Vo1d and XorDDoS; Kenya has seen ransomware targeting critical energy infrastructure; and Morocco has experienced coordinated government and education-sector disruptions via DDoS and website defacement attacks.

The report highlights five major shifts shaping Africa’s cyber risk in 2025.

Traditional ransomware has evolved into data-leak extortion, AI-generated deception is widespread, and identity has emerged as the new security perimeter.

Weak cybersecurity, the report warned, can now affect international market access under regulations such as the EU’s NIS2 Directive, making digital resilience an economic necessity.

The study urged African businesses and governments to adopt prevention-first security strategies, including continuous risk assessment, regulatory readiness, and public-private collaboration.

Oseghale emphasised that, as AI reshapes operations, cybersecurity must shift from reaction to prediction.

“The real challenge is not adopting new technology but securing the trust that underpins it,” he said.

Jumia’s Data Shows Nigerians Turning to Digital Retail to Navigate Inflation Pressures

Published

Kindly share this post

As Black Friday 2025 unfolds across Nigeria, new insights from Jumia’s Q3 2025 financial results reveal that more Nigerians are relying on digital retail to navigate inflation and rising living costs.

The data points to a more deliberate, value-driven shopper, one using online platforms to stretch budgets, compare options quickly, and extract more value from each purchase.

Jumia reported a 30 percent year-on-year increase in physical goods orders, while Gross Merchandise Value for physical goods rose by 43 percent.

This stronger GMV growth highlights a clear behavioural shift: consumers are assembling higher-value baskets by combining essentials with premium or long-term household items. Online retail is serving as a tool for strategic planning, not just convenience.

According to Temidayo Ojo, Chief Executive Officer of Jumia Nigeria, Black Friday now plays a more critical economic role. “Households are using digital retail to defend purchasing power. They plan their lists, compare prices instantly, and rely on the reliability and convenience that e-commerce offers,” he said.

This year’s Black Friday trends show growing demand in categories that directly support daily living. Household essentials and FMCG products are seeing significant uptake as families stock up during price drops. Home and kitchen equipment is also experiencing stronger demand as shoppers prioritise practical, durable tools. Affordable fashion and beauty products are gaining momentum as discounts make them more accessible.

Consumer behaviour in the lead-up to the sales period further reinforces this shift. Jumia recorded a notable increase in “Add to Wishlist” and “Add to Cart” activity, signalling more planning and fewer impulse purchases. The gap between GMV and order growth indicates that customers are optimising baskets using bundles, vouchers, and promo combinations, behaviours uniquely suited to digital platforms.

With inflation intensifying the need for smarter buying, trust markers on Jumia, such as verified sellers, official brand stores, ratings, and clear return policies, are becoming more central to decision-making. Authenticity and durability now outweigh the appeal of the lowest price.

Jumia’s logistics footprint is making these benefits available nationwide. Its 30,000 sqm Isolo fulfilment centre, 480 pickup stations, and 62 logistics partners ensure that customers in secondary and peri-urban cities enjoy the same deals as those in major hubs, reducing travel burdens and adding financial value.

Overall, Jumia’s Q3 data and Black Friday trends show that Nigerians are turning to digital retail as a practical, strategic response to inflation, using e-commerce to manage budgets, preserve purchasing power, and make more informed buying decisions.
