Data Breaches in Nigeria Increase 64% in Q1 2023

By Adedapo Adesanya

Data breaches in Nigeria increased by 64 per cent, as 82,000 leaked accounts were recorded in the first three months of the year when compared with the last quarter of 2022.

This made Nigeria the 32nd most breached country in the world in the first three months of this year, according to the latest data from cybersecurity company, Surfshark, collected through its independent partners from 29,000 publicly available databases and aggregated by email addresses.

Globally, data breaches declined in the first quarter of 2023, with a total of 41.6 million accounts breached. This is almost 50 per cent less than the nearly 81 million seen in Q4’2022.

The increase in Nigeria’s data breaches moved the country from the previous position of 41 to 32, with around 50,000 breaches recorded in Q4 2022.

Russia was ranked 1st in the world (6.6 million), followed by the United States (5 million), Taiwan (3.9 million), France (3.2 million), and Spain (3.2 million), making the top five.

Taiwan saw the highest quarter-over-quarter increase (21x), placing its total of 4 million leaked accounts 3rd in Q1’2023. The country had only placed 26th in Q4 2022 with 191,000 breached users.

Globally, data breaches declined, dropping to one user account leaked every second in Q1 2023.

“According to Surfshark’s study, data breaches declined globally in the first quarter of 2023 if we compare it to the previous one,” says Agneska Sablovskaja, Lead Researcher at Surfshark. “However, the fact that over 40 million accounts were breached in just a few months is still a cause for concern. Those whose data was compromised are at an increased risk of being targeted by cybercriminals as their personal information can be utilized for phishing attacks, fraud, identity theft, and other serious cybercrimes.”

Surfshark showed that Europe was the most affected region by breaches in Q1’2023, followed by Asia and North America.

In the period under review, Europe was also the only region with a significant quarter-over-quarter increase in its statistics on data breaches. The number nearly doubled, growing from 9.9 million in Q4 2022 to 17.5 million in the first three months of 2023. To put this into perspective, 2 out of 5 accounts breached in Q1 2023 were of European origin, with 38 per cent of these being Russian. Within the region, the biggest quarter-over-quarter spikes in data breaches were recorded in Czechia (almost 9x), Armenia (around 6x), and Switzerland (6x).

Asia was the second-most vulnerable region, accounting for around a fourth of the quarter’s breaches (10.6M). The three countries that saw the highest quarter-over-quarter increase overall were all Asian — Taiwan and Saudi Arabia both had around 20 times more leaked accounts in Q1’2023 than in Q4’2022, while South Korea saw its number increase 12 times.

An additional 13 per cent of the accounts were North American (5.3 million). All other regions comprised less than 5 per cent of the quarter’s total. Out of all regions, Africa saw the greatest quarter-over-quarter decrease — a whopping 33 times, bringing its total of 18.6 million leaked accounts in Q4 2022 down to 557,600  in Q1 2023.

Some of the biggest breaches by email count were Sberbank (Russia), with 2.9M accounts leaked, Weee! (United States) with 1.1M, and Zurich Insurance (Switzerland) with 756,700.

The ten most breached countries of Q1’2023, in descending order, are Russia, the U.S., Taiwan, France, Spain, India, Czechia, South Korea, and Italy. The highest growth in user victims was spotted in Taiwan (21x), Saudi Arabia (19x), South Korea (12x), Czechia (9x), and Armenia (7x).
