How Access to Whatsapp Encryption May Affect your Privacy

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.

NITDA Advocates AI, Security Integration for Sustainable Development

Kashifu Inuwa, CCIE, the Director General of the National Information Technology Development Agency (NITDA), has emphasised that integrating intelligence, security, and sustainability is critical to driving Nigeria’s digital transformation and global competitiveness.
Inuwa made the remarks on Tuesday in Kano while delivering a goodwill message at the opening of the 19th International Conference (CONNOVATE 2025) of the Nigerian Computer Society (NCS), themed “Intelligent, Secure, and Sustainable Innovations for a Connected World.”
Represented by Engr. Salisu Kaka, Director of E-Government and Digital Economy Development, Inuwa said the three elements were now indispensable drivers of national progress. He highlighted the need for their convergence to unlock new opportunities in Nigeria’s technology sector, citing Estonia’s X-Road platform — which enables 99% of government services online — as a global model.
“In Nigeria, trust is the ultimate currency in our high-stakes digital environment, where scams and cybercrime are prevalent. Security builds and protects this trust,” Abdullahi said.
He stressed that while security provides the foundation, intelligence builds the structure, pointing to Artificial Intelligence (AI), Machine Learning (ML), and data analytics as tools for addressing Nigeria’s complex challenges. Warning that “innovation without security is unsustainable,” he likened it to “a high-performance race car without brakes.”
The DG urged the next wave of Nigerian startups to go beyond digitising existing processes to creating new value, citing AI-powered wealth management and ML-driven remote diagnostics as examples.
He further highlighted the various Federal Ministry of Communications, Innovation and Digital Economy (FMCIDE) initiatives supporting this vision, including the National Centre for Artificial Intelligence and Robotics (NCAIR), the Computer Emergency Readiness and Response Team (CERRT), the Nigeria Data Protection Act (NDPA) 2023, the national digital identity programme, interoperable payments, and human capital initiatives such as the 3 Million Technical Talent (3MTT) and Digital Literacy for All (DL4ALL) programmes.
Inuwa cited example with International Federation for Information Processing (IFIP) President, Antony Wong, that called for stronger protection and strategic use of data in the Global South to safeguard indigenous knowledge. He stressed the importance of legal clarity on data ownership as Nigeria’s cultural heritage in medicine, ecology, and art is digitised and incorporated into AI systems. Wong praised Nigeria’s role in the recent World Intellectual Property Organization (WIPO) treaty protecting genetic resources and traditional knowledge.
Delivering his welcome address, the NCS President, Dr. Muhammad Sirajo, said the conference would serve as a platform for IT professionals to address critical issues, including intelligent systems, fintech, sustainable energy, and innovations in agriculture, health, education, and national planning.
“This conference will provide an interdisciplinary platform for researchers, practitioners, and educators to present and discuss recent innovations, trends, and solutions for improving technological systems,” Sirajo said.
The week-long event includes plenary sessions, a doctoral consortium, a youth and entrepreneurship forum, the Fellows Forum, the Annual General Meeting, an IT quiz competition for students, and an induction ceremony for new members. It will conclude with the election of new national executives, a dinner, and an awards night honouring contributions to the ICT sector.

AfDB Adopts AI to Fast-track Africa’s Development Blueprint

The African Development Bank (AfDB) is betting big on Artificial Intelligence (AI) as a catalyst for delivering Africa’s ambitious Agenda 2063.
With hands-on training in tools like ChatGPT and Google Gemini, the Bank believes the results could redefine how the continent plans, measures, and delivers its development goals.
Through its Joint Secretariat Support Office, the AfDB has provided technical and financial support to the 5th annual training workshop for African Union member states, focusing on the use of AI to track and implement the second ten-year plan (2024–2033) of Agenda 2063.
The five-day workshop, held in Lusaka, Zambia, was co-organised by the African Union Commission and the African Capacity Building Foundation.
Participants from across the continent rolled up their sleeves for hands-on training with emerging AI platforms like Ailyse, Google AI Studio, and Perplexity.
The goal of Africa’s multilateral development finance institution is to turn complex development data into actionable insights that can drive smarter decisions, faster interventions, and more accountable governance.
AbibuTamu, lead programme co-ordinator at the AfDB, said AI was now an indispensable tool for Africa’s future.
“These tools are not only revolutionizing how data is collected, analysed, and reported, they are also enabling more targeted policy interventions and efficient resource allocation,” Tamu told delegates.
Agenda 2063, dubbed “The Africa We Want,” is the African Union’s 50-year blueprint for inclusive growth and sustainable development. The second 10-year plan prioritises industrialisation, digital transformation, and sustainable livelihoods.
With AI now in the mix, African policymakers can track progress in real-time, spot bottlenecks before they choke projects, and reallocate resources where they are needed most.
The AfDB’s backing underscores a broader strategy of boosting both human and institutional capacity that propels African states to harness the digital revolution.
Beyond technical skills, the Lusaka workshop doubled as a peer-learning platform, with countries sharing real-world success stories on integrating AI into national planning and reporting.
“If Agenda 2063 is Africa’s long-term roadmap, this AI training is about upgrading the continent’s GPS that ensures leaders not only know the destination, but also have the intelligence to navigate every twist and turn on the way,” said Tamu.

Firm Shares Tips for Safer Remote Working

It is holiday season in many parts of the world. These days though, going on holiday does not always mean turning your back on office life – hybrid work cuts both ways.
Today’s widespread connectivity—available at airports, train stations, restaurants, hotels, and most indoor public spaces—makes staying connected easier than ever, with free Wi-Fi in many locations and reliable 4G or 5G coverage elsewhere, helping to facilitate a seamless blend of work and leisure even while on holiday.
This increase in connectivity among travellers has not gone unnoticed by cyber criminals. Kaspersky experts analysed nearly 25,000 free Wi-Fi spots in Paris ahead of the Summer Olympic Games and Paralympic Games. The analysis revealed that almost 25% of these networks had weak or no encryption, making users vulnerable to personal and banking data theft.
Travellers often have their guard down. The unfamiliar surroundings of a new location or a different language can throw up a useful smokescreen for a cyberattack, meaning additional care needs to be taken when logging on. Fortunately, a few smart tools and habits can help you stay protected while enjoying the flexibility of remote work.
Use a VPN for secure connections
A VPN is one of the most effective ways to safeguard users’ online activity, especially when working from unfamiliar locations. By encrypting Internet traffic, a VPN ensures that hackers can’t intercept sensitive data like login credentials or financial details. This is particularly important when accessing work emails or company files on public Wi-Fi, where cybercriminals often lurk.
Switch to an eSIM for reliable, secure mobile data
Another useful digital tool that provides a seamless way to stay connected using local mobile networks with no physical SIM card required is the eSIM. This is a game-changer for international travellers who want to avoid sky-high roaming charges or the hassle of hunting down temporary SIM cards in foreign countries.
With an eSIM, a user can download a local data plan before you even arrive at your destination, ensuring instant connectivity the moment you land. This eliminates the need to rely on unsecured Wi-Fi hotspots, significantly reducing your exposure to cyber threats.
Plus, many eSIM providers allow you to manage multiple profiles on a single device, making it easy to switch between work and personal data plans without juggling multiple phones.
Services like Kaspersky eSIM Store enables users to purchase and activate data plans in advance, track usage and top up as needed, all from a single app.
Enable two-factor authentication (2FA)
When travelling, people often leave devices unattended. To protect against unwanted people logging in, travellers should ensure two-factor authentication (2FA) is enabled on all critical accounts and that passwords are used on all devices.
Final tips for a secure workation
Even with a VPN, eSIM and 2FA in place, your devices still need strong defenses against malware, phishing scams and ransomware. Cybercriminals often target remote workers who may let their guard down while travelling, making real-time protection essential.
Modern antivirus software does more than just scan for viruses, it actively blocks malicious downloads, warns you about phishing attempts and even secures your passwords and financial data.
For the most robust security, consider a solution like Kaspersky Premium, which combines antivirus protection, a VPN and password management into a single, easy-to-use package.
By combining a VPN, eSIM and strong antivirus, you can work from anywhere with confidence, whether you’re sending emails from a poolside or joining a video call from a festival tent.
