Part 1: Introduction and De-Obfuscating and Reversing the User-Mode Agent Dropper SUMMARY This four part article series is a complete step-by-step tutorial on how to reverse engineer the ZeroAccess Rootkit. ZeroAcess is also known as the Smiscer or Max++ rootkit. You can either read along to gain an in-depth understand the thought process behind reverse engineering modern malware of this sophistication. The author prefers that you download the various tools mentioned within and reverse the rookit yourself as you read the article. Escala Desarrollo Psicomotor Brunet Lezyne Pdf Printer on this page. If you would like to use the malware sample used in these articles, download it here. InfoSec Institute would classify ZeroAccess as a sophisticated, advanced rootkit.

State-of-the-Art algorithms for rootkit detection are pre- sented in this paper. Forensic techniques to monitor the. Outside the memory image of ntoskrnl.exe (for SSDT) or win32k.sys (for Shadow SSDT). The driver exercises complex inner workings of a chip and checks for correct responses. This entry has information about the startup entry named Oddysee that points to the ntoskrnl.exe:kernel file. Or Alureon rootkit using. The ntoskrnl.exe it is.

It has 4 main components that we will reverse in great detail in this series of articles. ZeroAccess is a compartmentalized crimeware rootkit that serves as a platform for installing various malicious programs onto victim computers. It also supports features to make itself and the installed malicious programs impossible for power-users to remove and very difficult security experts to forensically analyze.

Ethical Hacking Training – Resources (InfoSec) At the conclusion of the analysis, we will trace the criminal origins of the ZeroAccess rootkit. We will discover that the purpose of this rootkit is to set up a stealthy, undetectable and un-removable platform to deliver malicious software to victim computers. We will also see that ZeroAccess is being currently used to deliver FakeAntivirus crimeware applications that trick users into paying $70 to remove the “antivirus”.

It could be used to deliver any malicious application, such as one that steals bank and credit card information in the future. Further analysis and network forensics supports that ZeroAccess is being hosted and originates from the Ecatel Network, which is controlled by the cybercrime syndicate RBN (Russian Business Network).

Symantec reports that 250,000+ computers have been infected with this rootkit. If 100% of users pay the $70 removal fee, it would net a total of $17,500,000. Download Other People more. As it is not likely that 100% of users will pay the fee, assuming that perhaps 30% will, resulting $5,250,000 in revenue for the RBN cybercrime syndicate. It has the following capabilities: • Modern persistence hooks into the OS – Make it very difficult to remove without damaging the host OS • Ability to use a low level API calls to carve out new disk volumes totally hidden from the infected victim, making traditional disk forensics impossible or difficult.
