Tizeti Launches Voice Calling Service WifiCall.ng

Published

Kindly share this post

Nigerian ISP leader Tizeti has launched an unlimited voice service app for Android and iOS mobile devices – WifiCall.ng,

Targeted at both individuals and businesses, users will be able to make and receive crystal clear, unlimited voice calls to anywhere in the world via IP phones or web portal.

The new product from Tizeti will be rolled out for Nigerian mobile phone numbers initially and subscribers with a +234 line will be able to use the service from anywhere in the world.

Built by the Tizeti team to tackle the issue of expensive phone calls on the continent, WifiCall is a first for not only the Nigerian ISP space but the African ISP space, providing users with a versatile, user-friendly interface, giving them access to a modern version of the “yellow pages”.

Implementation of the WifiCall platform is expected to reduce calling costs for businesses by 30-50%, with monthly subscriptions starting from N6,000 a month.

Unlike WhatsApp, WifiCall subscribers can call any phone number in the world, using their data package. For businesses WifiCall allows ease of a variety of client services and internal communications.

Key product features for the WiFiCall app include

–   Customisable dashboard

–    Calling statistics

–   Personalised digital receptionist messages for multi-line requirements whereby companies can create and manage queues

–    One click phone number search + search engine of business phone numbers

–   Subscribers can select their own number

–   Multi-user sub-account management with ability to top up online and allocate call credits to users.

–   Management of users within a calling space

The service comes with a number of additional innovative features, such as allowing mobile users to place calls directly from Twitter by tweeting phone numbers to @wificallng while on the social network, a feature developed with SMEs in mind, so they can provide seamless customer service.

Looking to make sure tech platforms can build services around the WifiCall product, developers will have access to the API suite within the platform, to tailor product-based solutions for businesses.

This extends past the wide variety of features already on offeracross web and mobile including the ability to top-up credit online, allocate call credit to multiple users as well as create digital receptionists and queues.

Kendall Ananyi, CEO and Co-Founder of Tizeti says “WifiCall.ng is reinventing our traditional understanding of phone communication using next-generation Cloud and AI technology, bringing voice communications in Nigeria into the 21st century.

“Our goal continues to be to reduce the cost of data and accelerate the rate of connectivity across the continent – this is a first step in continuing to bridge the digital divide that exists. We are excited to continue pushing boundaries in ICT infrastructure and maintain our competitive edge by offering quality and unlimited data service”.

According to the Alliance for Affordable Internet (A4AI), affordable internet is defined as 1GB of data costing no more than 2% of monthly income. Based on the current estimated national minimum wage in Nigeria of N30,000 per month, the current average rate for 1GB of data at N1,000 is significantly higher than the prescribed N600.

Ifeanyi Okonkwo, Tizeti’s Chief Operations Officer adds, “Tizeti has developed a system that meets the needs of a wide selection of Nigerians.

Whether it’s a household with a handful of users or a business who wants to setup a fully-fledged call centre solution, they can all do this in minutes at a fraction of the cost.

Previously, setting up a voice service of any size was only available to mega businesses and multi-tenant estates and it would take months to develop and required significant CAPEX to deploy.

WifiCall.ng has created a viable solution for Nigerians, further expanding our extensive reach nationwide”.

Tizeti operates widely as a “Comcast for Africa” and builds and operates solar-powered towers in Nigeria, while also providing residences and businesses with unlimited high speed broadband internet; covering over 90% of Lagos to date.

Since graduating from Y Combinator’s Winter 2017 batch, the company has installed over 12,000 public Wifi hotspots within Nigeria with 500,000 users, also partnering with Facebook to offer Express Wi-Fi to roll out thousands of internet hotspots across Nigeria’s capital. The company has since expanded its services to Ghana with new consumer-facing brand Wifi.Africa.

FG Launches Online Visa Approval Centre

Published

Kindly share this post

Dr. Olubunmi Tunji-Ojo, minister of Interior, has announced the launch of an Online Visa Approval Center to eliminate bureaucratic bottlenecks and reduce corruption in the visa application process.

FG Launches Online Visa Approval Centre

Commissioned by the President in December, the new system ensures that applicants no longer need to visit a visa office, know anyone in the system, or lobby for approvals.

At a stakeholders’ sensitisation workshop on the implementation of the Nigeria Visa Policy (NVP) 2025, yesterday in Abuja, Dr. Tunji-Ojo said the visa is considered a very important document by the government because it is an instrument of migration management and an instrument of economic development.

The minister explained that Nigeria has to strike a delicate balance between national security and, of course, the ease of migration.

“And we think that it’s something that we can do and something we will do.

“We don’t have a physical Visa Approval Center. If you apply for a Nigerian visa anywhere in the world, you do so online. We process it here in Nigeria, and if approved, you receive your e-visa in your email,” he explained.

To enhance efficiency, the government has set a 48-hour deadline for processing e-visas.

“It is unprofessional and unacceptable for the Nigeria Immigration Service not to approve or provide feedback within 48 hours,” the minister stated.

“It breaks my heart that people need to lobby to even get visas to Nigeria. It shouldn’t be so. It shouldn’t be.

“For anybody that is qualified, for anybody that wants to do legitimate activities in Nigeria, such people should be able to come to Nigeria easily. And this is why we are opening our space. Mr. President is interested in foreign direct investments.”

Further, he said Nigeria is interested in partnering with the rest of the world to develop its economy but, “We can’t do that when we allow bottlenecks to hold us down. So these reforms, basically, are aimed at opening our space, enhancing national security, and we hope that the primary responsibilities of the visa scheme will be achieved.”

Kemi Nandap, controller general, Nigeria Immigration Service (NIS), said the NIS would fully digitize its e-visa platform and reduce visa classifications from 79 to 44 to enhance accessibility, transparency, and efficiency in the new visa policy.

She said, “At the core of this policy is the new e-visa platform—a fully digitized, centralized system that revolutionizes how foreign nationals interact with our country’s entry procedures. As part of this transformation, the Nigerian Visa Policy 2024 underwent a comprehensive review, resulting in a significant reduction in visa classifications from 79 to 44.

“These categories have been logically grouped to simplify procedures, reduce complexities, and greatly improve the user experience. Importantly, we have maintained the original purpose and intent of each visa class throughout this reform.”

Firm Discovers Sophisticated Chrome Zero-day Exploit Used in Active Attacks

Published

on

Kindly share this post

Kaspersky has identified and helped patch a sophisticated zero-day vulnerability in Google Chrome (CVE-2025-2783) that allowed attackers to bypass the browser’s sandbox protection system.

The exploit, discovered by Kaspersky’s Global Research and Analysis Team (GReAT), required no user interaction beyond clicking a malicious link and demonstrated exceptional technical complexity. Kaspersky researchers have been acknowledged by Google for discovering and reporting this vulnerability.

In mid-March 2025, Kaspersky detected a wave of infections triggered when users clicked personalised phishing links delivered via email. After clicking, no additional action was needed to compromise their systems.

Once Kaspersky’s analysis confirmed that the exploit leveraged a previously unknown vulnerability in the latest version of Google Chrome, Kaspersky swiftly alerted Google’s security team. A security patch for the vulnerability was released on March 25, 2025.

Kaspersky researchers dubbed the campaign “Operation ForumTroll”, as attackers sent personalised phishing emails inviting recipients to the “Primakov Readings” forum. These lures targeted media outlets, educational institutions, and government organisations in Russia.

The malicious links were extremely short-lived to evade detection, and in most cases ultimately redirected to the legitimate website for “Primakov Readings” once the exploit was taken down.

The zero-day vulnerability in Chrome was only part of a chain that included at least two exploits: a still-unobtained remote code execution (RCE) exploit that apparently launched the attack, while the sandbox escape discovered by Kaspersky constituted the second stage. Analysis of the malware’s functionality suggests the operation was designed primarily for espionage. All evidence points to an Advanced Persistent Threat (APT) group.

“This vulnerability stands out among the dozens of zero-days we’ve discovered over the years,” said Boris Larin, principal security researcher at Kaspersky GReAT. “The exploit bypassed Chrome’s sandbox protection without performing any obviously malicious operations – it’s as if the security boundary simply didn’t exist.

The technical sophistication displayed here indicates development by highly skilled actors with substantial resources. We strongly advise all users to update their Google Chrome and any Chromium-based browser to the latest version to protect against this vulnerability.”

Google has credited Kaspersky for uncovering and reporting the issue, reflecting the company’s ongoing commitment to collaboration with the global cybersecurity community and ensuring user safety.

Kaspersky continues to investigate Operation ForumTroll. Further details, including a technical analysis of the exploits and malicious payload, will be released in a forthcoming report once Google Chrome user security is assured.

Meanwhile, all Kaspersky products detect and protect against this exploit chain and associated malware, ensuring users are shielded from the threat.

This discovery follows Kaspersky GReAT’s previous identification of another Chrome zero-day (CVE-2024-4947), which was exploited last year by the Lazarus APT group in a cryptocurrency theft campaign.

In that case, Kaspersky researchers found a type confusion bug in Google’s V8 JavaScript engine that enabled attackers to bypass security features through a fake cryptogame website.
