First, it shows that UEFI rootkits are a real threat, and not merely an attractive conference topic.
|
|
This makes rootkits hard to detect, persistent, and able to capture practically all data on the infected computer.

To defeat anti ad blockers, the researchers say they've borrowed techniques from rootkits, which are often used for malware but can be adapted to "hide their existence and activities" from ad-blocking detectors.
|
|
From a security standpoint, now that its keys have been released, having Secure Boot turned on is more or less no different than having Secure Boot turned off, bringing rootkits back into the threat landscape.

The software, devised by Arvind Narayanan, Dillon Reisman, Jonathan Mayer, and Grant Storey, is novel in two major ways: First, it looks at the struggle between advertising and ad blockers as fundamentally a security problem that can be fought in much the same way antivirus programs attempt to block malware, using techniques borrowed from rootkits and built-in web browser customizability to stealthily block ads without being detected.

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.
|

Hoglund also founded and operated rootkit.com, a popular site devoted to the subject of rootkits. Several well known rootkits and anti- rootkits were hosted from rootkit.com, including Jamie Butler's FU rootkit, Hacker Defender by HF, Bluepill by Joanna Rutkowska and Alexander Tereshkin, ShadowWalker by Sherri Sparks, FUTo by Peter Silberman, BootKit by Derek Soeder (eEye), and AFX Rootkit by Aphex.

Anti-virus software can attempt to scan for rootkits. A rootkit is a type of malware designed to gain administrative-level control over a computer system without being detected. Rootkits can change how the operating system functions and in some cases can tamper with the anti-virus program and render it ineffective. Rootkits are also difficult to remove, in some cases requiring a complete re-installation of the operating system.

Version 7.0 successfully identified all six actively running rootkits, four of six inactive rootkits, and was only able to remove two of six rootkits. The firewall correctly blocked all attempted outside connections, with a reasonable level of security when left on default settings. This version drops support for the Windows 98, 2000, and NT. Windows XP Service Pack 2 is required, except in the case of XP Professional x64 edition. Vista is supported as well.
|
|
Rootkits can prevent themselves from getting listed in the Task Manager, thereby preventing their detection and termination using it.
|
|
Once malicious software is installed on a system, it is essential that it stays concealed, to avoid detection. Software packages known as rootkits allow this concealment, by modifying the host's operating system so that the malware is hidden from the user. Rootkits can prevent a harmful process from being visible in the system's list of processes, or keep its files from being read. Some types of harmful software contain routines to evade identification and/or removal attempts, not merely to hide themselves.

Rubenking noted that the beta version sets Windows Update into fully automatic mode, although it can be turned off again through Windows Control Panel. Some full scans took more than an hour on infected systems; a scan on a clean system took 35 minutes. An on-demand scan test Rubenking conducted in June 2009 with the beta version found 89 percent of all malware samples: 30 percent of the commercial keyloggers, 67 percent of rootkits, but only half of the scareware samples. The product's real-time protection found 83 percent of all malware and blocked the majority of it: 40 percent of the commercial keyloggers and 78 percent of the rootkits were found.

One of the programs would install and "phone home" with reports on the user's private listening habits - even if the user refused its end-user license agreement (EULA), while the other was not mentioned in the EULA at all. Both programs contained code from several pieces of copylefted free software in an apparent infringement of copyright, and configured the operating system to hide the software's existence, leading to both programs being classified as rootkits. Sony BMG initially denied that the rootkits were harmful. It then released, for one of the programs, an "uninstaller" that only un-hid the program, installed additional software which could not be easily removed, collected an email address from the user, and introduced further security vulnerabilities.

The System Service Descriptor Table (SSDT) is an internal dispatch table within Microsoft Windows. Hooking SSDT calls is often used as a technique in both Windows rootkits and antivirus software. In 2010, many computer security products which relied on hooking SSDT calls were shown to be vulnerable to exploits using race conditions to attack the products' security checks.

Rootkits specialize in hiding themselves and other programs. Hacker Defender (hxdef) is an open source rootkit for Windows. It can hide its files, its process, its registry entries, and its port in multiple DLLs. Although it has a simple command-line interface as a back door, it is often better to use its ability to hide a more appropriate tool.

ESET Mobile Antivirus was aimed at protecting smartphones from viruses, spyware, adware, trojans, worms, rootkits, and other unwanted software. It also provided antispam filtering for SMS messages. Versions for Windows Mobile and Symbian OS were available. ESET discontinued ESET Mobile Antivirus in January 2011 and provides ESET Mobile Security as a free upgrade to licensed users of ESET Mobile Antivirus.

It is also widely used in benchmarking programs, for example frame rate measuring in 3D games, where the output and input is done through hooking. Hooking can also be used by malicious code. For example, rootkits, pieces of software that try to make themselves invisible by faking the output of API calls that would otherwise reveal their existence, often use hooking techniques.

StopBadware now focuses on web-based malware and presently defines badware as "software that fundamentally disregards a user's choice about how his or her computer or network connection will be used." This includes viruses, Trojans, rootkits, botnets, spyware, scareware, and many other types of malware. A badware website is a website that helps distribute badware, either intentionally or because it has been compromised.

The use of hypervisor technology by malware and rootkits installing themselves as a hypervisor below the operating system, known as hyperjacking, can make them more difficult to detect because the malware could intercept any operations of the operating system (such as someone entering a password) without the anti- malware software necessarily detecting it (since the malware runs below the entire operating system). Implementation of the concept has allegedly occurred in the SubVirt laboratory rootkit (developed jointly by Microsoft and University of Michigan researchers) as well as in the Blue Pill malware package. However, such assertions have been disputed by others who claim that it would be possible to detect the presence of a hypervisor-based rootkit. In 2009, researchers from Microsoft and North Carolina State University demonstrated a hypervisor-layer anti-rootkit called Hooksafe that can provide generic protection against kernel-mode rootkits.

Usually the only indication of failure is that, at the end of the knock sequence, the port expected to be open is not opened. No packets are sent to the remote user at any time. While this technique for securing access to remote network daemons has not been widely adopted by the security community, it has been actively used in many rootkits even before year 2000.

Then, under the pseudonym Wicked Rose, he formed the Network Crack Program Hacker Group (NCPH Group) and recruited other talented hackers from his school. He found a funding source (an unknown benefactor) and started attacking US sites. After an initial round of successful attacks, his funding was tripled. All through 2006, NCPH built sophisticated rootkits and launched a barrage of attacks against multiple US government agencies.

Riskware, a portmanteau of risk and software, is a word used to describe software whose installation and execution poses a possible yet not definite risk to a host computer. Relatively normal programs can often fall into the category of riskware as some applications can be modified for another purpose and used against the computer user or owner.Christopher C. Elisan: Malware, Rootkits & Botnets. Mcgraw-Hill, Professional, October 2012, , p. 33-37.

The Vundo Trojan (commonly known as Vundo, Virtumonde or Virtumondo, and sometimes referred to as MS Juan) is either a Trojan horse or a computer worm that is known to cause popups and advertising for rogue antispyware programs, and sporadically other misbehavior including performance degradation and denial of service with some websites including Google and Facebook. It also is used to deliver other malware to its host computers. Later versions include rootkits and ransomware.

The term "virus" is also misused by extension to refer to other types of malware. "Malware" encompasses computer viruses along with many other forms of malicious software, such as computer "worms", ransomware, spyware, adware, trojan horses, keyloggers, rootkits, bootkits, malicious Browser Helper Object (BHOs), and other malicious software. The majority of active malware threats are trojan horse programs or computer worms rather than computer viruses. The term computer virus, coined by Fred Cohen in 1985, is a misnomer.

ClamAV is currently tested daily in comparative tests against other antivirus products on Shadowserver. In 2011, Shadowserver tested over 25 million samples against ClamAV and numerous other antivirus products. Out of the 25 million samples tested, ClamAV scored 76.60% ranking 12 out of 19, a higher rating than some much more established competitors. In the 2008 AV-Test, which compared ClamAV to other antivirus software, it rated: on-demand: very poor; false positives: poor; response time: very good; rootkits: very poor.

Other programs are to obscure the presence of the intruder. These obscuring programs may include false versions of standard network utilities such as netstat, or programs that can remove all data from the log files of a computer that relate to the intruder. Yet other programs of a rootkit may be used to survey the network or to overhear more passwords that are travelling over it. Rootkits may also give the means to change the very operating system of the computer it is installed on.

GameGuard uses rootkits to proactively prevent cheat software from running. GameGuard hides the game application process, monitors the entire memory range, terminates applications defined by the game vendor and INCA Internet to be cheats (QIP for example), blocks certain calls to Direct X functions and Windows APIs, keylogs keyboard input, and auto-updates itself to change as new possible threats surface. Since GameGuard essentially works like a rootkit, players may experience unintended and potentially unwanted side effects. If set, GameGuard blocks any installation or activation of hardware and peripherals (e.g.

The Guardian reported that one-fifth of British companies had been charged over $10,000 to unlock their files and that there was an increasing demand for anti-ransomware technology. After Endpoint's inception, the beta was reportedly downloaded by some 200,000 businesses and consumers in the first six months of the year. Malwarebytes also has numerous tools such as a Junkware Removal Tool to remove adware, an Anti-Rootkit Beta to remove and repair rootkits, StartUpLITE to boost the speed of the Windows reboot and FileASSASSIN to prevent locked files.

Turla is a Russian-language threat actor known for its covert exfiltration tactics such as the use of hijacked satellite connections, waterholing of government websites, covert channel backdoors, rootkits, and deception tactics. The group's roots trace back to the once famous Agent.BTZ, a computer virus which had the ability to replicate itself as well as to scan for and steal data. The virus was used to briefly cripple the United States military, and was described as "the most significant breach of U.S. military computers ever" by a senior Pentagon official.

In 2016, two DarkMatter whistleblowers and multiple other security researchers expressed concerns that DarkMatter intended to become a certificate authority (CA). This would give it the technical capability to create fraudulent certificates, which would allow fraudulent websites or software updates to convincingly masquerade as legitimate ones. Such capabilities, if misused, would allow DarkMatter to more easily deploy rootkits to targets' devices, and to decrypt HTTPS communications of Firefox users via man-in-the-middle attacks. On 28 December 2017, DarkMatter requested that Mozilla include it as a trusted CA in the Firefox web browser.

Sarah Hicks, Symantec's vice president of consumer product management, voiced concern over Windows Vista 64-bit's PatchGuard feature. PatchGuard was designed by Microsoft to ensure the integrity of the kernel, a part of an operating system which interacts with the hardware. Rootkits may hide in an operating system's kernel, complicating removal. Mike Dalton, European president of McAfee said, "The decision to build a wall around the kernel with the assumption it can't be breached is ridiculous", claiming Microsoft was preventing security vendors from effectively protecting the kernel while promoting its own security product, Windows Live OneCare.

This early product monitored the behaviour of executables in real-time and would block system calls that breached its rules, thus providing protection. It offered protection against buffer overflow attacks and could successfully detect rootkits that attempted to hide themselves in memory or on disk. At the end of 2002, the company received investment from South East Growth Fund and in early 2003 from private investors through an angel network, Hotbed. In 2003, the company rebranded to Prevx and in June 2004 launched its first product for the Windows platform, “Prevx Home - Beta”, offered as a freeware download.

Most BIOS implementations are specifically designed to work with a particular computer or motherboard model, by interfacing with various devices that make up the complementary system chipset. Originally, BIOS firmware was stored in a ROM chip on the PC motherboard. In modern computer systems, the BIOS contents are stored on flash memory so it can be rewritten without removing the chip from the motherboard. This allows easy, end-user updates to the BIOS firmware so new features can be added or bugs can be fixed, but it also creates a possibility for the computer to become infected with BIOS rootkits.

ClamTk, an open source antivirus based on the ClamAV antivirus engine, originally developed by Tomasz Kojm in 2001 Antivirus software, or anti-virus software (abbreviated to AV software), also known as anti-malware, is a computer program used to prevent, detect, and remove malware. Antivirus software was originally developed to detect and remove computer viruses, hence the name. However, with the proliferation of other kinds of malware, antivirus software started to provide protection from other computer threats. In particular, modern antivirus software can protect users from: malicious browser helper objects (BHOs), browser hijackers, ransomware, keyloggers, backdoors, rootkits, trojan horses, worms, malicious LSPs, dialers, fraudtools, adware and spyware.

He holds a patent on fault injection methods for software testing, and fuzzy hashing for computer forensics. Due to an email leak in 2011, Hoglund is well known to have worked for the U.S. Government and Intelligence Community in the development of rootkits and exploit material. It was also shown that he and his team at HBGary had performed a great deal of research on Chinese Government hackers commonly known as APT (Advanced persistent threat). For a time, his company HBGary was the target of a great deal of media coverage and controversy following the 2011 email leak (see below, Controversy and email leak).

The attacker only needs to access the computer once more as Administrator to gain full access to all those subsequently EFS-encrypted files. Even using Syskey mode 2 or 3 does not protect against this attack, because the attacker could back up the encrypted files offline, restore them elsewhere and use the DRA's private key to decrypt the files. If such a malicious insider can gain physical access to the computer, all security features are to be considered irrelevant, because they could also install rootkits, software or even hardware keyloggers etc. on the computer – which is potentially much more interesting and effective than overwriting DRA policy.

Microsoft Security Essentials (MSE) is an antivirus software (AV) that provides protection against different types of malicious software, such as computer viruses, spyware, rootkits, and trojan horses. Prior to version 4.5, MSE ran on , Windows Vista, and Windows 7, but not on Windows 8 and later versions, which have built-in AV components known as Windows Defender. MSE 4.5 and later versions do not run on Windows XP. The license agreement allows home users and small businesses to install and use the product free-of-charge. It replaces Windows Live OneCare, a discontinued commercial subscription-based AV service, and the free Windows Defender, which only protected users from spyware until Windows8.

PrivateCore is a venture-backed startup located in Palo Alto, California that develops software to secure server data through server attestation and memory encryption. The company's attestation and memory encryption technology fills a gap that exists between “data in motion” encryption (TLS, email encryption) and “data at rest” encryption (disk encryption, tape encryption) by protecting “data in use” (random access memory). PrivateCore memory encryption technology protects against threats to servers such as cold boot attacks, hardware advanced persistent threats, rootkits/bootkits, computer hardware supply chain attacks, and physical threats to servers from insiders. PrivateCore was acquired by Facebook, a deal that was announced on 7 August 2014.

Cheat Engine can inject code into other processes, and as such, most antivirus programs mistake it for a virus. There are versions that avoid this false identification at the cost of many features (those which rely upon code injection). The most common reason for these false identifications is that Cheat Engine makes use of some techniques also used in Trojan rootkits to gain access to parts of the system and therefore gets flagged as suspicious, especially if heuristic scanning is enabled in the antivirus program's settings. Newer versions of Cheat Engine are less likely to be blocked by antivirus programs, so features like code injection can be used without problems.

Anti-tampering technology typically makes the software somewhat larger and also has a performance impact. There are no provably secure software anti-tampering methods; thus, the field is an arms race between attackers and software anti-tampering technologies. Tampering can be malicious, to gain control over some aspect of the software with an unauthorized modification that alters the computer program code and behaviour. Examples include installing rootkits and backdoors, disabling security monitoring, subverting authentication, malicious code injection for the purposes of data theft or to achieve higher user privileges, altering control flow and communication, license code bypassing for the purpose of software piracy, code interference to extract data or algorithms and counterfeiting.

A ring −3 rootkit was demonstrated by Invisible Things Lab for the Q35 chipset; it does not work for the later Q45 chipset as Intel implemented additional protections. The exploit worked by remapping the normally protected memory region (top 16 MB of RAM) reserved for the ME. The ME rootkit could be installed regardless of whether the AMT is present or enabled on the system, as the chipset always contains the ARC ME coprocessor. (The "−3" designation was chosen because the ME coprocessor works even when the system is in the S3 state, thus it was considered a layer below the System Management Mode rootkits.) For the vulnerable Q35 chipset, a keystroke logger ME-based rootkit was demonstrated by Patrick Stewin.

In addition, Steam's DRM remains one of the most secure available, but is very non-intrusive compared to schemes like SecuROM, which, in installing kernel-mode drivers (often somewhat inaccurately referred to as "rootkits"), are often incompatible with certain hardware configurations and many pieces of third-party security software (such as software firewalls and anti-virus applications), a problem that does not plague Steam. Steam also allows consumers to back up their copy of Half-Life 2 as well as other games that are downloadable through Steam onto CDs or DVDs. To complement this feature many fans have created box coverings for jewel cases that can be downloaded and printed, giving birth to a wide variety of game packaging styles and designs. Java games for cellphones are distributed almost exclusively via the internet.

Steam's primary service is to allow its users to download games and other software that they have in their virtual software libraries to their local computers as game cache files (GCFs). Initially, Valve was required to be the publisher for these games since they had sole access to the Steam's database and engine, but with the introduction of the Steamworks software development kit (SDK) in May 2008, anyone could potentially become a publisher to Steam, outside of Valve's involvement to curate games on the service. Prior to 2009, most games released on Steam had traditional anti-piracy measures, including the assignment and distribution of product keys and support for digital rights management software tools such as SecuROM or non-malicious rootkits. With an update to the Steamworks SDK in March 2009, Valve added its "Custom Executable Generation" (CEG) approach into the Steamworks SDK that removed the need for these other measures.

Tipton was let into the room on November 20, 2010 to manually adjust the time on the draw computer to reflect daylight saving time; it was alleged that while Tipton was in the room, he used a USB flash drive to install self-destructing malware on the random number generator computer, presumably to rig a draw. Tipton's co- workers described him as having been "obsessed" with rootkits at the time. It was also noted that on that day, security cameras were configured to record only for "roughly one second per minute", a change the prosecutors believed was made to prevent anything suspicious from being recorded. In an April 13, 2015 statement, Iowa Lottery CEO Terry Rich explained that MUSL had implemented stronger security measures to protect the integrity of its draws, including new equipment and software to conduct the drawing, updated security protocols for the draw room, new security cameras, and further separation of duties.

Lacking an Apple II computer and Apple-Cat modem, in addition to their historical value, perhaps the most useful and interesting part of the Phantom Access programs is the extensive documentation Kroupa wrote.Phantom Access Documentation (converted to text) (Retrieved from Textfiles.com) In addition to explaining how to program the sub-modules, the documents provide an extensive overview of phreaking information, information about the other programs in the Phantom Access series (which appear to have been other system penetration tools and rootkits, before the term "rootkit" existed), and the eventual goal of the whole series, which seems to have been turning the entire Apple II computer and Apple-Cat modem into a programmable phreaking box, which could be plugged into the computers Kroupa and other LOD members were abandoning the Apple platform and switching over to (NeXT, Sun and SGI hardware).Voices in My Head: MindVox The Overture by Patrick Kroupa, 1992 From the Phantom Access documentation: :The eventual goal of Phantom Access was to realize a fully automated system for the Apple-Cat modem.

In January 2008, Anti-Malware Test Lab gave Avira "gold" status for proactive virus detection and detection/removal of rootkits. AV-Comparatives awarded Avira its "AV Product of the Year" award in its "Summary Report 2008." In April 2009, PC Pro awarded Avira Premium Security Suite 9 the maximum six stars and a place on its A-list for Internet security software."Avira Premium Security Suite 9 review" at PC Pro (27 July 2010) In August 2009, Avira performed at a 98.9% percent overall malware detection rate, and was the fastest for both on-demand scans and on-access scans conducted by PC World magazine, which ranked it first on its website."Avira AntiVir Personal" by Erik Larkin, PC World (24 August 2009) Avira was among the first companies to receive OESIS OK Gold Certification, indicating that both the antispyware and antivirus components of several of its security products achieved the maximum compatibility score with widespread network technologies such as SSL/TLS VPN and Network Access Control from companies including Juniper Networks, Cisco Systems, and SonicWALL.

The term "computer virus" may be used as an overarching phrase to include all types of true viruses, malware, including computer worms, Trojan horses, most rootkits, spyware, dishonest adware and other malicious and unwanted software (though all are technically unique), and proves to be quite financially lucrative for criminal organizations, offering greater opportunities for fraud and extortion whilst increasing security, secrecy and anonymity. Worms may be utilized by organized crime groups to exploit security vulnerabilities (duplicating itself automatically across other computers a given network), while a Trojan horse is a program that appears harmless but hides malicious functions (such as retrieval of stored confidential data, corruption of information, or interception of transmissions). Worms and Trojan horses, like viruses, may harm a computer system's data or performance. Applying the Internet model of organized crime, the proliferation of computer viruses and other malicious software promotes a sense of detachment between the perpetrator (whether that be the criminal organization or another individual) and the victim; this may help to explain vast increases in cyber-crime such as these for the purpose of ideological crime or terrorism.
