The war in Ukraine is a reality. A war that can have a major impact and in which cyber-attacks are also used as a weapon, affecting not only Ukraine, but also European companies and organisations. Our cyber-security experts issue a warning for an increased cyber risk which is also of great importance for your company.

Aim shifts from making money to malice

Ukraine is facing cyber attacks of unprecedented magnitude against its government, its critical infrastructures and other crucial services and businesses. The country has been struggling with major cyber-attacks since 2015, but now there is literally digital warfare with a malicious purpose. Here's how: Cybercriminals use malware to infiltrate computer networks and encrypt files. In classic ransomware attacks, victims can pay to get a key to get everything back. However, Ukraine is now facing a so-called wiper malware that infects computers and irreparably damages files. Neither the computer nor the files can be used after that. This malware is spreading across national borders. Experts have already identified this wiper in Latvia and Lithuania and warn that the infection may spread to other European companies and organisations.


Reality check: how prepared are you?

Recently, it was in the news that Dutch companies had been hacked. The National Coordinator for Counterterrorism and Security indicates that there are no specific threats at the moment, but due to the rapid development of the war, things could escalate at any moment.
