Beyond the disturbing images of the invasion of Ukraine that began February 24 are the invisible cyberattacks that preceded it and continue to be waged on Ukraine by Russian state-sponsored and other threat actors, which also threaten the West. Vedere Labs, Forescout’s threat intelligence and research team, is closely monitoring the evolution of cyber activities connected to the Russian-Ukrainian conflict.
A reverse proxy server (or reverse proxy) facilitates a user’s requests to a web server/application server and the server’s response.

Given that active cyber warfare has broken out alongside Russia’s active invasion of Ukraine - from Russian wiper malware to Anonymous hacking Russian state TV - CISA’s recent “Shields Up” memo is a timely insight into some of the TTPs defenders of critical infrastructure should be keeping an eye out for. Let’s break down the four key areas outlined in the memo and examine ways they can be detected with network data.
