Ukrainian IP Network: The Cybersecurity Headache of 2025!
Ukrainian IP network FDN3 has been stirring up cyber trouble, with massive brute-force and password spraying campaigns. These antics, peaking in July 2025, target SSL VPN and RDP devices. The activity highlights the ongoing issues with bulletproof hosting and the shadowy networks keeping cybercriminals in business.
Hot Take:
Ukrainian IP networks seem to be the Houdinis of the digital world, magically vanishing from blocklists only to reappear with new tricks up their sleeves. They’re like the digital equivalent of a game of Whack-a-Mole—just when you think you’ve got them, they pop up somewhere else with a new set of IPs and a fresh batch of trouble. If these networks were any more slippery, they’d be starring in their own action movie, complete with daring escapes and plot twists that would make James Bond blush.
Key Points:
– Ukrainian IP network flagged for massive brute-force and password spraying campaigns targeting SSL VPN and RDP devices.
– Networks involved are part of a wider infrastructure, evading blocklists and conducting abusive activities.
– Activities linked to ransomware groups using these techniques for network breaches.
– Ties to bulletproof hosting providers and offshore ISPs providing anonymity for malicious activities.
– New findings connect these networks to broader cybercrime infrastructure, including the PolarEdge botnet.
