Abstract

“ NGR Bot (also known as Dorkbot) was examined to be a user-mode rootkit that could be remotely controlled via Internet-Relay-Chat (IRC) protocol. It was designed with the intention to steal digital identity, perform denial of service, and manipulate the domain name resolution (see image below for the impact analysis). This article aims to provide some technical insights of this NGR Bot V1.0.3 sample (MD5 “1CA4E2F3C8C327F8D823EB0E94896538″) on the following topics: (1) Encryption & tampering detection mechanism, (2) Functionalities, (3) Hooking technique, and the (4) Architecture Set-up for communicating with this malware.
