Explanation:
Malware, or “Malicious Software”, are types of adware or spyware programmed by attackers trying to infect your computer, steal your data, or even gain access to your network. A total of 91.9 million URLs serving malicious code were detected in the fall of 2012. Malware is a generic term for many different types of “infections” that may be downloaded to your computer.
Phishing is a scam where an attacker uses fake or partial information to try to trick someone into revealing passwords and other confidential information, typically via email or social media. LastPass helps protect you against fake-website phishing attacks by not filling your credentials when it does not see a URL or field match.
Viruses are programs that infect software on your computer. When you run this software, it causes the virus to spread throughout your computer. Basically, the virus can replicate itself and continue spreading to other computers (much like a biological virus), causing hardware and software issues.
Worms are programs that replicate and spread through a network, infecting multiple devices. Unlike a virus, a worm does not need to attach itself to an existing software. Worms cause harm to a network, while viruses cause harm to a targeted computer.
Trojans are software that “appear” genuine, and invites the user to run it, but instead, it releases a malicious load that deletes your files and harms your computer. 49% of all Kaspersky Lab threat detections in Q2 of 2012 were multi-functional Trojans.
A backdoor is a method of bypassing normal authentication to illegally gain remote access to the machine and the data on it. It can be installed to computers by Trojans or worms.
Spyware is a software that gathers a users information without their knowledge, and sends this data to third parties.
KeyLogger software captures the keystrokes entered on your computer keyboard. The keylogger software is then able to transmit these keystrokes where they can be viewed. As a prevention against keyloggers, when using a public or “untrusted” computer, LastPass offers the option to input your master password with a ‘Virtual Keyboard’, allowing you to login without using the keyboard to type your master password.
