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 ...
Detecting rootkits is separated into many complex layers that include integrity checking and behavioral detection. By checking the CPU usage, ongoing and outgoing network traffic, or the signatures of drivers, simple anti-virus tools can detect common rootkits. However, this is not the case with a kernel type rootkit.
In 2007, a group of researchers challenged Rutkowska to put Blue Pill against their rootkit detector software at that year's Black Hat conference, [6] but the deal was deemed a no-go following Rutkowska's request for $384,000 in funding as a prerequisite for entering the competition. [7]
Rootkits are notoriously used by the black hat hacking community. A rootkit allows an attacker to subvert a compromised system. This subversion can take place at the application level, as is the case for the early rootkits that replaced a set of common administrative tools, but can be more dangerous when it occurs at the kernel level.
GMER is a software tool written by a Polish researcher Przemysław Gmerek, for detecting and removing rootkits. [1] [2] It runs on Microsoft Windows and has support for Windows NT, 2000, XP, Vista, 7, 8 and 10. With version 2.0.18327 full support for Windows x64 is added. [3] [4] [5]
The Advanced Intrusion Detection Environment (AIDE) was initially developed as a free replacement for Tripwire licensed under the terms of the GNU General Public License (GPL). The primary developers are named as Rami Lehti and Pablo Virolainen, who are both associated with the Tampere University of Technology , along with Richard van den Berg ...
Chkrootkit (Check Rootkit) is a widely used Unix-based utility designed to aid system administrators in examining their systems for rootkits. Operating as a shell script , it leverages common Unix / Linux tools such as the strings and grep command.
CyberArk was founded in 1999 in Israel [5] [6] by Udi Mokady [7] and Alon N. Cohen. In June 2014, CyberArk filed for an initial public offering (IPO) with the Securities and Exchange Commission, listing 2013 revenues of $66.2 million. [8] CyberArk became a public company the same year, trading on the NASDAQ as CYBR. [9]
