It is not uncommon for a rootkit to disable the event logging capacity of an operating system, in an attempt to hide evidence of an attack. Rootkits can, in theory, subvert any operating system activities. [62] The "perfect rootkit" can be thought of as similar to a "perfect crime": one that nobody realizes has taken place. Rootkits also take a ...
The Blue Pill concept is to trap a running instance of the operating system by starting a thin hypervisor and virtualizing the rest of the machine under it. The previous operating system would still maintain its existing references to all devices and files, but nearly anything, including hardware interrupts, requests for data and even the ...
Mebroot is a master boot record based rootkit used by botnets including Torpig.It is a sophisticated Trojan horse that uses stealth techniques to hide itself from the user. The Trojan opens a back door on the victim's computer which allows the attacker complete control over the computer.
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]
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.
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. Because of how these types of rootkits can hide from the system table and event viewer, detecting them requires looking for hooked functions ...
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 ...
The report [3] goes into great detail about how the botnet operates. During the UCSB research team's ten-day takeover of the botnet, Torpig was able to retrieve login information for 8,310 accounts at 410 different institutions, and 1,660 unique credit and debit card numbers from victims in the U.S. (49%), Italy (12%), Spain (8%), and 40 other ...
