7% of Nigerians Encountered Phishing Attacks in 2022—Kaspersky
By Adedapo Adesanya
Data from Kaspersky showed that 7 per cent of Nigerian computer users fell for phishing attacks in 2022, as the company’s anti-phishing system prevented more than 500 million attempts at accessing fraudulent websites globally in 2022. This is twice more compared to 2021 figures.
In Africa, 8.7 per cent of individuals and corporate users were affected by phishing attacks on their devices, with South African users affected the most by phishing.
For the country, attacks stood at 9.7 per cent, followed by Kenya at 8.4 per cent, followed by Nigeria’s 7 per cent.
In Kaspersky’s Spam and Phishing in 2022 Report, the company’s anti-phishing system successfully blocked 507,851,735 attempts to access fraudulent content globally in 2022, twice the number of attacks thwarted in 2021.
The company’s experts discovered that throughout 2022 cybercriminals increasingly turned to phishing.
“The sphere most frequently targeted with phishing attacks was delivery services. Fraudsters send fake emails pretending to be from well-known delivery companies and claim there is an issue with delivery. The email includes a link to a fake website, which asks for personal information or financial details. If the victim falls for the scam, they could lose their identity and banking information, which may be sold to websites on the dark web.”
Giving a breakdown, the report indicated that financial phishing was the most commonly targeted category, with online stores and online financial services being the affected businesses.
Among the financial phishing attempts in Nigeria, 31.1 per cent were through websites of fake payment systems, 51.2 per cent through fake online stores, and 17.8 per cent through fake online bank portals.
Kaspersky experts have also highlighted a global trend in the phishing landscape of 2022: an increase in the distribution of attacks through messengers, with the majority of blocked attempts coming from WhatsApp, followed by Telegram and Viber.
There is also growing demand among cybercriminals for social media credentials, with criminals exploiting people’s curiosity and desire for privacy by offering fake updates and verified account statuses on social media platforms.
Moreover, the experts found that cryptocurrency scams and market events, like the pandemic, are still being used by phishing attackers to steal sensitive information from people who are afraid and worried. These scammers are taking advantage of people’s fears and concerns to steal their sensitive information.
Speaking on this, Mr Olga Svistunova, a security expert at Kaspersky, said, “Phishing is one of the most prevalent and pernicious threats in the cybersecurity landscape. Being the gateway to many of the worst cyber threats, phishing pages are the first step in a long chain of events that can result in identity theft, financial loss, and reputational damage for both individual consumers and businesses. It’s crucial for everyone to understand the threat and take action to protect themselves.”
In order to avoid becoming a victim of spam or phishing-based scams, Kaspersky experts advise that users only open emails and click links if they are sure they can trust the sender, check the spelling of a website’s URL if they suspect that they are faced with a phishing page, and also check the legitimacy of the sender.
It also encouraged the use of a proven security solution when surfing the web, which is capable of spotting and blocking spam and phishing campaigns.

One of the high points of the 2025 re:Invent was the unveiling of Graviton5, the fifth generation of custom Arm-based server processors from Amazon Web Services (AWS).
Many tech enthusiasts believe that the company pushed the limits with Graviton5, its most powerful and efficient CPU, frontier agents that can work autonomously for days, an expansion of the Amazon Nova model family, Trainium3 UltraServers, and AWS AI Factories suitable for implementing AI infrastructure in customers’ existing data centres.
Graviton5—the company’s most powerful and efficient CPU
As cloud workloads grow in complexity, organizations face a persistent challenge to deliver faster performance at lower costs and meet sustainability commitments without trade-offs.
AWS’ new Graviton5-based Amazon EC2 M9g delivers up to 25% higher performance than its previous generation, with 192 cores per chip and 5x larger cache.
For the third year in a row, more than half of new CPU capacity added to AWS is powered by Graviton, with 98 per cent of the top 1,000 EC2 customers—including Adobe, Airbnb, Epic Games, Formula 1, Pinterest, SAP, and Siemens—already benefiting from Graviton’s price performance advantages.
Expansion of Nova family of models and pioneers “open training” with Nova Forge
Amazon is expanding its Nova portfolio with four new models that deliver industry-leading price-performance across reasoning, multimodal processing, conversational AI, code generation, and agentic tasks. Nova Forge pioneers “open training,” giving organizations access to pre-trained model checkpoints and the ability to blend proprietary data with Amazon Nova-curated datasets.
Nova Act achieves breakthrough 90% reliability for browser-based UI automation workflows built by early customers. Companies like Reddit are using Nova Forge to replace multiple specialized models with a single solution, while Hertz accelerated development velocity by 5x with Nova Act.
Addition of 3 frontier agents, a new class of AI agents that work as an extension of your software development team
Frontier agents represent a step-change in what agents can do. They’re autonomous, scalable, and can work for hours or days without intervention. AWS announced three frontier agents—Kiro autonomous agent, AWS Security Agent, and AWS DevOps Agent. Kiro autonomous agent acts as a virtual developer for your team, AWS Security Agent is your own security consultant, and AWS DevOps Agent is your on-call operational team.
Companies, including Commonwealth Bank of Australia, SmugMug, and Wester Governors University have used one or more of these agents to transform the software development lifecycle.
Unveiling Trainium3 UltraServers
As AI models grow in size and complexity, training cutting-edge models requires infrastructure investments that only a handful of organizations can afford.
Amazon EC2 Trn3 UltraServers, powered by AWS’s first 3nm AI chip, pack up to 144 Trainium3 chips into a single integrated system, delivering up to 4.4x more compute performance and 4x greater energy efficiency than Trainium2 UltraServers.
Customers achieve 3x higher throughput per chip while delivering 4x faster response times, reducing training times from months to weeks. Customers including Anthropic, Karakuri, Metagenomi, NetoAI, Ricoh, and Splash Music are reducing training and inference costs by up to 50 per cent with Trainium, while Decart is achieving 4x faster inference for real-time generative video at half the cost of GPUs, and Amazon Bedrock is already serving production workloads on Trainium3.

The National Information Technology Development Agency (NITDA) has issued an advisory on new vulnerabilities in ChatGPT that could expose users to data-leakage attacks.
According to the advisory, researchers discovered seven vulnerabilities affecting GPT-4o and GPT-5 models that allow attackers to manipulate ChatGPT through indirect prompt injection.
The agency explained that hidden instructions placed inside webpages, comments, or Uniform Resource Locators (URLs) can trigger unintended commands during regular browsing, summarisation, or search actions.
“By embedding hidden instructions in webpages, comments, or crafted URLs, attackers can cause ChatGPT to execute unintended commands simply through normal browsing, summarization, or search actions,” they stated.
The warning followed rising concerns about AI-powered tools interacting with unsafe web content and the growing dependence on ChatGPT for business, research, and public-sector tasks.
NITDA added that some flaws allow the bypassing of safety controls by masking malicious content behind trusted domains.
Other weaknesses take advantage of markdown rendering bugs, enabling hidden instructions to pass undetected.
It explained that in severe cases, attackers can poison ChatGPT’s memory, forcing the system to retain malicious instructions that influence future conversations
They stated that while OpenAI has fixed parts of the issue, Large-Language Models (LLMs) still struggle to reliably separate genuine user intent from malicious data.
The Agency warned that these vulnerabilities could lead to a range of cybersecurity threats, including unauthorised actions carried out by the model; unintended exposure of user information; manipulated or misleading outputs; and long-term behavioural changes caused by memory poisoning, among others.
It advised Nigerians, businesses, and government institutions to adopt several precautionary steps to stay safe. These include limiting or disabling the browsing and summarisation of untrusted websites within enterprise environments and enabling features like browsing or memory only when necessary.
It also recommended regular updates to deployed GPT-4o and GPT-5 models to ensure known vulnerabilities are patched.
