Any software that, when installed, performs unwanted or malicious activity, often for the benefit of a third party. Adware, spyware, and viruses are some well-known forms of malware.
A scheme in which cyberattackers conceal malicious software files (malware) on a website to infect computers that visit the site. Often, the attackers place these files on legitimate websites without the site owner’s knowledge. When victims click a link that leads to the malicious software files, their computers are infected. In some cases, attackers distribute links to the malicious files through spam, adware, or mobile in-app advertising. In other cases, they rely on the site’s popularity to attract victims.
man-in-the-middle attack(MITM attack)
Any attack in which the attacker secretly interposes software or a computer system to intercept, capture, alter, or replay messages between two parties. Attackers use MITM attacks to capture information that one party transmits to another. Installing malware to record a computer user’s keystrokes is one form of MITM attack. In more elaborate schemes, an attacker impersonates one or both parties in an email exchange. During the email exchange, the attacker aims to dupe one of the parties into divulging sensitive information or authorizing a financial transaction.
Material Subcontracting Arrangement(MSA)
Maximal Starting Repertoire(MSR)
- Code points that are eligible for use in labels for top-level domains.
- A default set of Whole Label Evaluation Rules for the root zone.
The MSR is updated from time to time based on feedback from the community and to accommodate relevant updates to the Unicode Standard. Each new version of the MSR is given a version number in the form MSR-# (e.g., MSR-1, MSR-2, MSR-3).
An identifier (formerly known as a MIME type) that some protocols use to indicate the nature and format of files sent over the Internet. A file’s media type appears in the header of a file transmission and indicates the file’s type and subtype. Common type/subtype values include:
