This can cause a number of serious security problems. Several security software vendors, including Microsoft, regard XCP as a trojan horse, spyware, or rootkit. [2] MacOS systems that were used to play these CDs may have been affected with a similar program, MediaMax. [3]
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.
Sony BMG quickly released software to remove the rootkit component of XCP from affected Microsoft Windows computers, [15] but after Russinovich analyzed the utility, he reported in his blog that it only exacerbated the security problems and raised further concerns about privacy. [16]
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.
The term rootkit is a compound of "root" (the traditional name of the privileged account on Unix-like operating systems) and the word "kit" (which refers to the software components that implement the tool). [2] The term "rootkit" has negative connotations through its association with malware. [1]
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]
Malicious code is a broad category that encompasses a number of threats to cyber-security. In essence it is any “hardware, software, or firmware that is intentionally included or inserted in a system for a harmful purpose.” [6] Commonly referred to as malware it includes computer viruses, worms, Trojan horses, keyloggers, BOTs, Rootkits, and any software security exploits.
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 ...
