Summary Three key takeaways from our analysis of Vidar infrastructure: Russian VPN gateways are potentially providing anonymity for Vidar operators / customers, making it more challenging for analysts to have a complete overview of this threat. These gateways now appear to be migrating to Tor. Vidar operators appear to be expanding their infrastructure, so analysts need to keep them in their sights. We expect a new wave of customers and as a result, an increase of campaigns in the upcoming weeks

Cluster25 researchers analyzed several campaigns (also publicly reported by CERT-AGID) that used phishing emails to spread an InfoStealer malware written in .NET through an infection chain that involves Windows Shortcut (LNK) files and Batch Scripts (BAT). Taking into account the used TTPs and extracted evidence, the attacks seem perpetrated by the same adversary (internally named AUI001).

Cyber threat intelligence largely involves the tracking and studying of the adversaries outside of your network. Gaining counterintelligence about your adversaries' capabilities and weaponry is one of the final building blocks for managing a strong cyber defense. In the pursuit of performing this duty, I have been studying how to discover adversary infrastructure on the internet. One good way of doing this has been via leveraging the scan data available through the popular Shodan search engine. If you've not used it before, Shodan periodically scans the entire internet and makes it available for users to query through. It is often used to monitor networks, look for vulnerabilities, and ensure the security of an organization's perimeter.
