Most cyber attacks in Ukraine go unnoticed, with only about 20% becoming public knowledge.

This was stated by Serhiy Kharyuk, founder of AmonSul and co-founder of the largest Ukrainian cybersecurity community, in an interview with EP.

"From my observations, for every publicly known incident, there are at least four others that remain unspoken. This is especially true for the private sector," he noted.

Kharyuk cited an example where one bot collecting personal data contained information that some data was allegedly "leaked" from a pharmacy network. Although there was no official confirmation of a breach, the mere appearance of such data indicates a possible hack.

Regarding whether the government should publicly report on cyber incidents, Kharyuk emphasized that this is a complex issue, especially during wartime. In the case of military structures, publicity may be unwise. However, for the civilian sector, transparency can be a learning opportunity for other organizations.

"For example, Kyivstar only acknowledged that they were hacked, but real collaboration only began after the UZ breach. Then the operator's specialists came to assist with recovery. But this is like help after a person has broken their leg," he added.
