onion web traffic. The bot connects to the hidden service passing through the Tor2Web proxy pointing to an onion address that identifies the C&C server that remains hidden. The routing mechanism relies on the Tor2Web proxy to redirect.

“Proxy-aware Malware over Tor network.”.

The Botnet traffic is routed to the C&C server through the Tor network that encrypts it making hard its analysis.īrown proposed the following two botnet models that exploit the Tor network:

Cleaning of C&C servers and of the infected hosts.

Obscuration of the IP addresses assigned to the C&C server.

Once uncovered a botnet, the security researchers and law enforcement have different options to eradicate it: Security researchers use traffic analysis to detect botnet activities and to localize the C&C servers typically they do this by using Intrusion Detection Systems and network analyzers.

Availability of Authenticated Hidden Services.

The principal advantages of Tor-based botnets are: Tor-Botnetĭuring the Defcon Conference in 2010, the security engineer Dennis Brown made an interesting speech on Tor-based botnets he explained which are pro and cons for hiding C&C servers in the Tor Network. The use of anonymizing networks is quite common, but it has pro and cons, let’s see in detail which are advantages and problems. Malware authors use to hide C&C servers in the darknet to make botnet resilient against operations run by law enforcement and security firms. Hiding command and control infrastructure in the dark web

2017 –Ransomware-as-a-Service dubbed Shifr RaaS that allows creating ransomware compiling 3 form fields.

2017 – MacRansom is the first Mac ransomware offered as a RaaS Service.

2017 – MACSPY – Remote Access Trojan as a service on Dark web.Many types of malware are directly controlled by servers hosted on both Tor and I2P, and it is quite easy to find Ransom-as-a-Service (RaaS) in the darknets.īelow just a few examples of malware that were discovered in the last 12 months leveraging darknets for their operations: In just three years the situation has completely changed, almost any ransomware today relies on hidden services in the Tor network for the payment infrastructure. The results were surprising, the number of malware that were using darknet was limited, with a prevalence of Tor-based malicious code.įigure 1 – Malware using C&C in the Dark Web (Security Affairs 2015) Just three years ago I made a rapid analysis to determine the number of malicious codes that were exploiting both the Tor network and the I2P dark net to hide their command and control servers. The use of dark nets represents a design choice for malware developers that use them to hide the command and control servers.
