Data breaches in Ukraine are growing fast. According to a Surfshark study, Ukraine climbed from 47th to 6th place worldwide by the number of compromised records in Q3 2026. In just three months, about 2.6 million records were compromised in Ukraine.
Data breaches: what the numbers show
Worldwide, 121.8 million accounts were compromised in Q3. That is 13% more than in the previous quarter. In other words, about 940 records leak every minute.
The United States, Brazil, the United Kingdom, India and Australia suffered the most. Ukraine comes right after them.
Other studies confirm the trend. According to the Microsoft Digital Defense Report 2026, Ukraine ranked first in Europe and third in the world by the number of cyberattacks in the first half of the year. In addition, CERT-UA handled about 200 incidents against citizens from January to September, compared with about 80 a year earlier. Many of these attacks were phishing campaigns that aimed to steal Telegram and Signal accounts.
Small companies are under attack too
Attackers increasingly target small and medium-sized businesses. Globally, breaches at companies with up to 300 employees almost doubled over the year. The main threats for them are ransomware, account takeover and unpatched software.
Another trend is attacks through contractors and cloud providers. Third parties were involved in one in three leaks. As a result, even a well-protected organization can suffer because of a weak link in its supply chain.

How to protect your company from data breaches
Most leaks happen not because of complex attacks but because of simple mistakes: weak passwords, excessive access rights and outdated software. However, you can find and fix them in advance. For this, you need a systematic approach:
- Know your risks. Understand what data the company stores, where it lives and who can access it.
- Test your defenses. Look for vulnerabilities and configuration errors on a regular basis.
- Manage security by the standard. Have clear rules for access, incident response and work with contractors.
