Rootkit detection is difficult because a rootkit may be able to subvert the software that is intended to find it. Detection methods include using an alternative and trusted operating system, behavior-based methods, signature scanning, difference scanning, and memory dump analysis.
rkhunter (Rootkit Hunter) is a Unix-based tool that scans for rootkits, backdoors and possible local exploits. [1] It does this by comparing SHA-1 hashes of important files with known good ones in online databases, searching for default directories (of rootkits), wrong permissions, hidden files, suspicious strings in kernel modules, and special tests for Linux and FreeBSD. rkhunter is notable ...
chkrootkit (Check Rootkit) is a Unix-based program intended to help system administrators check their system for known rootkits.It is a shell script using common UNIX/Linux tools like the strings and grep commands to search core system programs for signatures and for comparing a traversal of the /proc filesystem with the output of the ps (process status) command to look for discrepancies.
Detecting rootkits is a major challenge for anti-virus programs. Rootkits have full administrative access to the computer and are invisible to users and hidden from the list of running processes in the task manager. Rootkits can modify the inner workings of the operating system and tamper with antivirus programs. [147]
XCP.Sony.Rootkit loads a system filter driver which intercepts all calls for process, directory or registry listings, even those unrelated to the Sony BMG application. This rootkit driver modifies what information is visible to the operating system in order to cloak the Sony BMG software. This is commonly referred to as rootkit technology.
Alureon (also known as TDSS or TDL-4) is a trojan and rootkit created to steal data by intercepting a system's network traffic and searching for banking usernames and passwords, credit card data, PayPal information, social security numbers, and other sensitive user data. [1]
Rootkit and Malware Detection: Process and file level analysis to detect malicious applications and rootkits. Active Response: Respond to attacks and changes on the system in real time through multiple mechanisms including firewall policies, integration with 3rd parties such as CDN's and support portals, as well as self-healing actions.
It runs on Windows XP and Windows Server 2003 (32-bit-versions only). Its output lists Windows Registry and file system API discrepancies that may indicate the presence of a rootkit. It is the same tool that triggered the Sony BMG copy protection rootkit scandal. [2] RootkitRevealer is no longer being developed. [1]: 08:16
