Threats Frequently Asked Questions
ORIENTATION...
Notes: Adware is NOT a separate category threat - adware is a Spyware category threat. Antispyware products do NOT remove antivirus category threats such as viruses and worms. Antivirus products do NOT remove antispyware category threats such as adware and spyware threats. Rootkits are a SEPERATE threat - though most antivirus companies have added anti-rootkit scanning in the antivirus product since the middle of the past decade (2000-2010). Traditionally and ongoing, there are many anti-rootkit scanners for detection and removal available.
A bot is the payload to infect computers into a botnet. These can infect with the world's best defense products in place - simply disabling them etc. There have been several break throughs in defenses such as original Symantec AntiBot. Botnet infection has replaced ALL threats as the worst plague to the internet and computer users currently since approximately year 2005-6. Their entry is common like clicking something warned against like virus attachments. The best defense is up to date antivirus and antispyware - as a bot payload can be built in pieces at a time as the system defense may be spied on by Botmaster / Botherder Command And Control employed for picking attacks against known weak products installed in the computer user machine. A botnet infection can be built by several installations secretly by viruses, worms, trojans and downloader trojans, rootkits, spyware kits, virus kits, backdoor threats, safe mode with networking, etc - and various other instant full payload
infections via reverse engineering of many security devices/wares/appliances etc.

MSNBC: The lowdown on 'Bots'
The lowdown on 'Bots'
http://www.msnbc.msn.com/id/17805145/
What are ‘bots’?
“Bots” – short for robots – are hijacked computers that are infected by computer viruses and then used by criminals
and pranksters for a variety of criminal and malicious purposes.
Who controls ‘bots’?
The criminals behind “bots,” known as “bot herders,” assemble armies of infected computers -- often between 50,000
and 70,000 PCs strong -- that they can then charge customers for the use of. The going rate for sending spam is $5,000
a day or more, according to Howard Schmidt, former White House cyberczar.
What are ‘bots’ used for?
“Bots” are used to spread malicious programs, send spam, fuel “pump-and-dump stock schemes and launch
denial-of-service attacks, among other things.
How many ‘bots” are there?
Internet founding father Vint Cerf recently estimated that 150 million computers have been hijacked. Most other experts
believe that figure is too high, but there is general agreement that “bots” number in the millions, if not the tens of millions.
How can I tell if my computer is a ‘bot’?
You can’t necessarily. Antivirus software will catch most known viruses, but new ones are being created all the time.
It used to be that poor performance often tipped off users that their computers had been infected, but “bot herders” now
distribute tasks among thousands of computers to avoid tell-tale crashes.

In November 2004, a critical Microsoft security vulnerability (MS04-028) was discovered which could
allow attackers to embed malicious code inside JPEG image files. Until that time, JPEG image files were considered immune to attack. To effectively deal with this vulnerability, security and IT professionals need to incorporate six new and critical content security requirements into their networks.

Glossary of Malware
Security Threat Glossary
http://www.westcoastlabs.org/
Attack Vectors
Method by which malware attempts to enter a system. This generally refers to a protocol such as HTTP, SMTP, FTP, IRC, IM, etc. Anti-Malware - A term generally applied to a software application which combats malicious code through detection and/or removal.
Drive-by Download
This technique is used to surreptitiously download malware onto a user's machine. The attack generally includes exploits to browser or OS vulnerabilities, and may be separated into several pieces so that a user may be directed to several websites or domains to avoid detection by anti-malware programs.
FTP Threats
Malware which uses FTP as an attack vector.
Malicious URL
URLs which direct a user to a Web Threat.
SMTP Threats
Malware which uses email as an attack vector Application-specific attacks - Exploits or hacking attempts which seek to use a vulnerability in a particular software program to gain entrance onto a user's system.
Socially Engineered Attack
Exploits or hacking attempts which seek to use a user's susceptibility to fear, trust or titillation to gain entrance onto a user's system or information. Phishing and trojans are two types of attacks which rely almost exclusively on social engineering.
Undesirable URL
URLs which direct a user to content which may be considered inappropriate for certain contexts, such as "adult" or violent content, or network tools which could be used to compromise a network.
Web Threats
This is a category of threats delivered by HTTP which intend to perform actions which harm a user or their system. Phishing, drive-by downloads and sites which host malware can be considered to fall into this category.
Malware Glossary
Bots
The term Bot (short for robot) is a type of program, which has evolved from RATs (see Spyware definitions). A bot usually leverages an internet facing port to deliver a program that awaits a further command upon which it can take remote control of the system. Bots are often combined with other infected machines to form a botnet (a network of bot-infected machines). Bots are used to turn an individual machine into a "zombie" that can then be used for actions such as co-ordinated DoS attacks on websites, spamming, or hired/sold to others for such use.
Exploits
An Exploit is a piece of code designed to attack a vulnerability on a computer system, or such an attack. Hackers and writers of Malware look for announcements of such vulnerabilities by manufacturers and other sources and then attack machines, which have not been patched against the vulnerability. The code is designed to enable an activity that otherwise could not take place, or to avoid system restrictions preventing such an activity. Various payloads attached to the exploits may provide the attacker with a number of ways into the compromised system.
Rootkit
Although the term referred originally to Unix systems, the term has come to more widely mean a set of tools or programs that are used on a host system, often in conjunction with malware, to allow attackers to exploit said system or a network. Rootkits can be used to hide applications from third party scanners and the term is also coming to mean more generalized cloaking utilities that mask the attacker's activities. Recently the term rootkit has become more publicly known after the anti-copy security software on several Sony-BMG audio CDs displayed rootkit-like tendencies as part of their Digital Rights Management strategy.
Spyware
Spyware is a form of software that makes use of a user's internet connection without his or her knowledge, usually in order to covertly gather information about the user. Once installed, the Spyware may monitor user activity on the Internet and transmit that information in the background to someone else. Spyware can also gather information about addresses and even passwords and credit card numbers. Spyware is often unwittingly installed when users install another program, but can also be installed when a user simply visits a malicious website.
Types of Spyware used in the West Coast Labs Test Suites
Backdoor - A Backdoor is a secret or undocumented way of gaining access to a program, online service, computer or an entire computer network. Most Backdoors are designed to exploit a vulnerability in a system and open it to future access by an attacker. A Backdoor is a potential security risk in that it allows an attacker to gain unauthorized access to a computer and the files stored thereon.
Key Loggers - A Key Logger is a type of surveillance software that has the capability to record every keystroke to a log file (usually encrypted). A Key Logger recorder can record instant messages; email and any information typed using the keyboard. The log file created by the Key Logger can then be sent to a specified receiver. Some Key Logger programs will also record any e-mail addresses used and Web Sites visited.
Financials - A Financial is a program that has the capability of scanning a PC or network for information relating to financial transactions and then transmitting the data to a remote user.
Proxies - Proxies are designed to enable an external user to use a computer for their own purposes, for example, to launch DDoS attacks or send spam, so that the true originator of the attack cannot be traced.
Password Stealers and Crackers - A Password Stealer is a program resident on a computer, which is designed to intercept and report to an external person any passwords, held on that machine. A Password Cracker has the ability to decode any encrypted passwords.
Downloaders - A downloader is a file which when activated, downloads other files on to the system without the knowledge or consent of the user, those other files then carrying out malicious functions on the system.
Hijacker - A Hijacker is a file with the ability to change your default Internet home page and/or to create or alter other Web browser settings such as bookmarks and redirection of Internet searches or Internet browsing to commercial sites that could offend the user or breach corporate policies on inappropriate or illegal content.
RATs - A Remote Access Trojan (RAT) is a piece of malware designed to run and gain access to a remote computer across a network or the Internet in order to carry out a particular purpose on that remote computer, that purpose being malicious and without the consent of the remote system's owner or user. Access is usually gained by use of a backdoor, either already installed or included in the code of the RAT.
Trojan
Trojan Horses or Trojans are destructive programs that pretend to be benign applications. Unlike Viruses or Worms, Trojan Horses do not replicate themselves; they can be damaging to networks by delivering other types of Malware.
Virus
A Virus is a program or piece of code attached to a file or diskette's boot sector; it is loaded onto a computer without the user's knowledge. Viruses are manmade (though they can be corrupted in use to form new variants of the virus) and replicate themselves by attaching themselves to files or diskettes, often soaking up memory or hard disk space and bringing networks to a halt. Most recent viruses are internet-borne and capable of transmitting themselves across and bypassing security systems. Minor variants of the same virus are classed as families of viruses.
Worm
A Worm is an insidious program or algorithm that replicates itself over a computer network or by email system and usually performs malicious actions, such as using up the computer's resources or distributing pornography and possibly shutting the system down. Unlike Viruses, Worms copy themselves as standalone programs and do not attach themselves to other objects.
