Petya ransomware is currently bringing tears to the eyes of Swiss companies. After Wanna Cry a few weeks ago, cybercriminals have again attacked Swiss companies with ransomware. Swisscom Cybersecurity experts explain what’s going on.
The risk of spread over the network is low when you have the latest update status. Computers that have installed updates according to Swisscom’s recommendations are protected against exploitation of this vulnerability. The malware was analysed and its communication channels were blocked in the Swisscom network. The anti-virus solutions used by Swisscom recognise the previously known Trojan files and delete them automatically.
The biggest threat is users who are handling their e-mails with global administrator privileges, as the Trojan might use their privileges to infect other computers on the same network.
