In the wake of last week’s terrorist attack in Westminster, the British government on Sunday disclosed that its security services must have access to encrypted messaging applications such as WhatsApp, revealing it was used by the killer behind the parliament attack.

In this piece, Yudala – the largest online and offline retail chain – examines the benefits of WhatsApp encryption and why access to these encrypted messages by a third-party may mean less privacy for you…

Created in 2009 as an alternative to text messaging, WhatsApp is today one of the world’s most popular instant messaging service with more than one billion users in 180 countries.

According to a May 2016 report from research firm SimilarWeb, WhatsApp is the top chat app in 109 countries, including Brazil, India, and the United Kingdom. Facebook acquired WhatsApp in 2014 to make a bigger play in the rapidly-growing messaging market, along with its own Messenger platform. At the time the deal was announced, WhatsApp had 450 million users worldwide.

Khalid Masood, the 52-year-old Briton who killed four people before being shot dead in a rampage in Westminster on Wednesday, reportedly used WhatsApp to send a message some moments before the assault – a discovery that has seen the UK government determined to gain access to the end-to-end encrypted messages sent through the app.

Home Secretary Amber Rudd affirmed that it was “completely unacceptable” that police and security services had not been able to crack the heavily encrypted service.
“You can’t have a situation where you have terrorists talking to each other — where this terrorist sent a WhatsApp message — and it can’t be accessed,” she said.

WHAT DOES WHATSAPP END-TO-END ENCRYPTION MEAN?
WhatsApp’s end-to-end encryption ensures only you and the person you’re communicating with can read what is sent and nobody in between, not even WhatsApp. Your messages are secured with a lock and, only the recipient and you, have the special key needed to unlock and read your message. For added protection, every message you send has a unique lock and key. All of this happens automatically: no need to turn on settings or set up special secret chats to secure your messages.

It is also important to note that end-to-end encryption is always activated, provided all parties are using the latest version of WhatsApp. There is no way to turn off end-to-end encryption. End-to-end encryption is available when you and the people you message are on the latest versions of WhatsApp.

The benefits of end-to-end encryption on WhatsApp are numerous and has remained one of the major factors that has contributed to the growing popularity of the Facebook-owned service. These benefits include:

Privacy: With end-to-end encryption in place, people can communicate with each other and express themselves freely without fear of unintended people gaining access to their private stuff. This way, you can talk to your doctor about your medication, hold intimate chat sessions with your spouse/partner or have a discussion with an associate about a business proposal without the fear of being overheard or the call being tapped.

Safe group chats: Group chats are also safely encrypted, thereby lending an air of confidentiality to messages sent in such a forum. With encryption featuring in group chats, non-group members will have no clue at all about the happenings in the group. This makes it more attractive for people with like minds and interests to discuss their affairs in WhatsApp groups without the fear of being overheard.

Encryption works by default: Encryption setting is turned on by default by WhatsApp in all devices. If you are running the version of WhatsApp that has encryption support, you will be informed of this on your chat screen when you send messages across along with a lock symbol next to the confirmation screen. You can also verify the default ON setting by making use of a unique QR code on the phone of each contact in your list.

In case, for some reason, the default encryption setting does not get activated, you can do it yourself through a simple process. In your chat window, just click on your contact’s name at the top of the window to display his or her profile details. You will find an option to turn the encryption on.

WhatsApp can’t read your messages: End-to-end encryption means that even if it wanted to, WhatsApp cannot gain access to your messages. In other words, only the sender and receiver can read intended messages.

Not even WhatsApp employees or hackers will be able to gain access to the messages sent or received. This applies to any form of messages – text, images, videos and files.

Encryption works on all devices: The encryption in WhatsApp works using an open-source protocol known as Signal that is developed by an organization called Open Whsiper Systems. This company has worked in close association with WhatsApp in determining its requirements and the level of encryption to be provided.

The app ensures that smartphones featuring this app support the encryption and decryption keys to be applied to messages going out and coming into the device.

The encryption technology is supported by all recent WhatsApp versions running on Android, Windows, iPhones, and Nokia phones. Keeping in line with the usual trend, WhatsApp first introduced encryption on Android before extending it to other platforms.

Even in error, you are protected: WhatsApp has become very focused on making encryption mandatory that it now refuses to work on unencrypted messages.

If a person tries to send a contact an unencrypted message, WhatsApp will immediately prevent him or her from doing so.

Additionally, the sender will be informed that this is because the messages being sent from his or her end are not encrypted.

No server hacks with end-to-end encryption: When the encryption process was first implemented by WhatsApp, it took place over a central hub.

Messages management and key exchange coordination take place centrally, apart from central control of the encrypted code that is executed on both the servers and mobile phones.

However, this did not result in complete safety and paved way for end-to-end encryption. As a result, messages will get decrypted only on the receivers’ handsets rather than in between the server and the handsets.

Nigeria Takes the Lead in the Global WSIS+20 Digital Agenda

Published

Nigeria has unveiled a comprehensive, multi-pronged strategy designed to localise WSIS+20 commitments. This roadmap accelerates national transformation by prioritising robust infrastructure, transparent internet governance, and advanced cybersecurity through deep stakeholder collaboration.

Unveiled in New York at the Nigerian high-level side event titled “Re-Imagining Digital Cooperation for Sustainable Development: From WSIS+20 Vision to Local Action,” the strategy cements Nigeria’s position as a primary architect of the world’s digital future.

Speaking at the event, the Director General of the National Information Technology Development Agency (NITDA), Kashifu Inuwa, CCIE represented by Director, Corporate Planning and Strategy, Dr. Dimie Shively Wariowei said Nigeria’s approach is deliberately aligned with the four core activity areas identified under the ongoing WSIS+20 review process.

According to him, the focus areas provide a practical framework for translating global digital commitments into measurable national outcomes, ensuring that international resolutions drive inclusive growth and sustainable digital development at the country level.

Inuwa identified digital infrastructure as the foundation of effective localisation, noting persistent challenges in extending connectivity to underserved and remote communities. Beyond infrastructure gaps, he highlighted affordability constraints and digital literacy deficits, stressing that addressing these issues remains central to Nigeria’s digital inclusion drive.

He explained that government alone cannot shoulder the burden of nationwide digital infrastructure deployment, given Nigeria’s vast geographical spread, hence the adoption of collaborative Public-Private Partnership (PPP) models. He disclosed that Nigeria, in collaboration with the World Bank, is implementing a major fibre-optic project spanning about 90,000 kilometres nationwide to boost connectivity.

The NITDA DG also revealed that the current National Broadband Plan, which has guided broadband expansion in recent years, is nearing completion, with plans underway to renew and reposition it for the next five years. The renewed plan, he said, will strategically target increased broadband penetration as a catalyst for digital access and economic growth.

On internet governance, Inuwa referenced Nigeria’s active participation in the Internet Governance Forum (IGF), noting that the country successfully hosted its annual national IGF. He said the forum operates on a multi-stakeholder model that brings together government, the private sector, civil society and the technical community to foster cooperation and informed policy dialogue.

Cybersecurity, he added, remains a critical pillar of Nigeria’s localisation efforts. He cited the existing Cybersecurity Act and ongoing efforts to strengthen the legal framework through a reviewed version currently awaiting parliamentary approval. These measures, he said, are designed to mitigate risks associated with increased internet use and to protect users and critical digital infrastructure.

Inuwa further stressed Nigeria’s ambition to play a leadership role in advancing digital cooperation across Africa through inclusive, multi-stakeholder engagement. He underscored the importance of coordinated national data collection, noting that reliable, country-specific data is essential for tracking progress and presenting Africa’s digital development story on the global stage.

He concluded that sustained engagement and follow-up actions arising from the WSIS+20 review would strengthen digital cooperation among African countries and ensure that global digital commitments translate into tangible national and regional impact.

Stakeholders commended Nigeria’s efforts in the digital space, acknowledging the country’s growing role in shaping Africa’s digital future.

Earlier, Ms. Jennifer Chung, Co-Convener of the Informal Multi-Stakeholder Sounding Board (IMSB), praised Nigeria for convening a broad-based, multi-stakeholder delegation and for its commitment to the meaningful implementation of WSIS+20 outcomes.

Chung stressed the growing demand for localised WSIS follow-up mechanisms, noting that platforms such as the annual IGF, National and Regional IGF Initiatives (NRIs), and youth-led forums are vital for tracking progress towards the 2030 Agenda and Africa’s Agenda 2063.

She described the WSIS+20 review as a critical step toward effective monitoring, reliable data collection and evidence-based evaluation, particularly for developing countries in the Global South. According to her, these measures are essential to achieving WSIS targets and ensuring that no region is left behind.

Drawing parallels with the Asia-Pacific region, Chung noted that challenges around affordable and meaningful connectivity remain widespread across developing economies. She emphasised that expanding broadband penetration and reducing the cost of access are crucial to closing digital divides in Africa, Asia-Pacific and other parts of the Global South.

She also highlighted the need to enable active citizen participation in emerging technologies, including artificial intelligence and future innovations such as quantum technologies, stressing that inclusive digital access is key to maximising the benefits of digital transformation.

Reflecting on the WSIS+20 review process, Chung praised the innovative and inclusive approach adopted through the informal multi-stakeholder sounding board, describing it as one of the first of its kind in global digital governance. She called for sustained collaboration among governments, the private sector, civil society and the technical community to carry the WSIS vision from global commitments to local action.

United Bank for Africa (UBA) Plc has announced a $100 million financing partnership with CIG Motors, Lagride and the Lagos State Government to promote urban mobility and financial inclusion through a scheme tagged “Drive to Own.”

UBA Partners CIG Motors, Lagride, Launches $100m “Drive to Own” Scheme

Group Managing Director/CEO, United Bank for Africa(UBA) and, Chairman, LagRide, Chief Diana Chen, flagged by LagRide drivers, at the signing ceremony of $100 Million Expansion Facility, strengthening smart mobility, driver asset ownership of over 3,500 cars, financed by UBA in partnership with Lagos State Government and LagRide, held in Lagos on Tuesday.

 

The initiative, unveiled on Wednesday in Alausa, Lagos, will empower 3,500 drivers in the state by enabling them to own vehicles with an equity contribution of 10 per cent of the total cost, while the balance is payable over 48 months.

UBA’s Group Managing Director/CEO, Oliver Alawuba, described the scheme as transformational, noting that it would foster inclusive economic growth, support MSME development and create opportunities for the younger generation.

“This partnership with Lagride is transformational. It will drive inclusivity for economic growth and ensure progress for everyone,” he said.

Alawuba shared a personal story, recalling that his father worked as a driver and was able to fund his education through that income. He said the scheme would provide similar opportunities for many families.

UBA’s Head of SME Banking, Babatunde Ajayi, said the partnership reflected a rethinking of traditional banking models.

“Not every business has a shop. Some businesses have wheels. Every commercial driver is running a business, yet they have remained outside formal finance. We designed credit that fits their reality,” he said.

Chairman of Lagride, Diana Chen, said the company had built a data-driven and credit-ready mobility platform for drivers, stressing that transportation remained the backbone of Africa’s economic future.

“Lagride now stands as the most structured, data-driven and credit-ready mobility platform in Nigeria,” Chen said.

The partnership aligns the strengths of the three organisations, with UBA providing financial support, CIG Motors offering viable business opportunities, and Lagride delivering a technology-driven platform to ensure sustainable livelihoods for driver-partners.

Check Point Reveals Nigeria as Second Most Targeted African Country for Cyberattacks in November

Published

The November 2025 Global Threat Intelligence report released by Check Point Research on Tuesday, shows Nigerian organisations faced an average of 3,374 cyberattacks per week.

Making the country as one of the primary targets for cybercriminals in Africa last month, with a record of a staggering volume of digital threats despite an overall decline in attacks across the continent.

The report shows that this figure places Nigeria second among the four major African nations analysed, trailing only Angola, which topped the list with 4,251 weekly attacks per organisation.

While Africa as a whole saw a 13 percent year-on-year decrease in cyber incidents, Nigeria’s high numbers reveal a persistent vulnerability within its digital infrastructure. Kenya and South Africa followed Nigeria with 2,384 and 1,863 weekly attacks, respectively.

The report also identified government institutions and financial services as the most targeted sectors across Africa. Globally, the education and research sector remained the most frequent victim, hit by an average of 4,656 attacks per week.

A significant highlight of the report is the emerging threat posed by Generative Artificial Intelligence (GenAI). Check Point Research found that one in every 35 GenAI prompts submitted within corporate networks globally posed a high risk of sensitive data leakage.

In Nigeria and abroad, employees are increasingly using AI tools that operate outside of formal security frameworks. The report noted that 87 percent of organisations using GenAI were affected by ‘high-risk’ prompts, which often included the input of proprietary code, customer data, or internal communications into public AI models.

Ransomware continues to be a primary tool for extortion, with global incidents rising by 22 percent year-on-year. While North America remains the most targeted region for ransomware, the impact is increasingly felt in emerging markets like Nigeria.

The most active ransomware groups identified in November were Qilin, Clop, and Akira, which primarily targeted industrial manufacturing and consumer goods sectors.
