mysterious actor is running malicious tor

Since WIZARD SPIDER’s tool is used for exfiltration, the name Sidoh is fitting.

In the series, the character Sidoh has an item stolen by Ryuk. Sidoh (as well as Ryuk ) is the name of a character from the anime series Death Note. Sidoh (aka Ryuk Stealer) is a keyword-based exfiltration tool used by WIZARD SPIDER. Their toolset covers the entirety of the kill chain, from delivery to post-exploitation tools and big game hunting (BGH) ransomware, enabling WIZARD SPIDER to conduct a wide range of criminal activities against enterprise environments. This Russia-based eCrime group originally began deploying TrickBot in 2016 to conduct financial fraud, but has since evolved into a highly capable group with a diverse and potent arsenal, including Ryuk, Conti and BazarLoader.

However, despite this rule, servers with no contact information are often added to the Tor network, which is not strictly policed, mainly to ensure there's always a sufficiently large number of nodes to bounce and hide user traffic.WIZARD SPIDER is an established, high-profile and sophisticated eCrime group, originally known for the creation and operation of the TrickBot banking Trojan.

Servers added to the Tor network typically must have contact information included in their setup, such as an email address, so Tor network administrators and law enforcement can contact server operators in the case of a misconfiguration or file an abuse report. Their role is to encrypt and anonymize user traffic as it enters and leaves the Tor network, creating a giant mesh of proxy servers that bounce connections between each other and provide the much-needed privacy that Tor users come for. Some of these servers work as entry points (guards), others as middle relays, and others as exit points from the Tor network. The Record: Tracked as KAX17, the threat actor ran at its peak more than 900 malicious servers part of the Tor network, which typically tends to hover around a daily total of up to 9,000-10,000. Since at least 2017, a mysterious threat actor has run thousands of malicious servers in entry, middle, and exit positions of the Tor network in what a security researcher has described as an attempt to deanonymize Tor users.
