malware         
<security> Any software designed to do something that the user would not wish it to do, hasn't asked it to do, and often has no knowledge of until it's too late. Types of malware include backdoor, virus, worm, Trojan horse. Malware typically affects the system on which it is run, e.g. by deleting or corrupting files on the local disks. Since Internet connections became common, malware has increasingly targets remote systems. An early example was malware consisting of a malicious e-mail attachment that targeted security flaws in Microsoft Outlook (the most common e-mail client) to send itself to all the user's contacts. A more recent kind of malware "recruits" the infected computer to become part of a botnet consisting of thousands of infected computers that can then be remotely controlled and used to launch DDoS attacks.

Malware         
Malware (a portmanteau for malicious software) is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive users access to information or which unknowingly interferes with the user's computer security and privacy. By contrast, software that causes harm due to some deficiency is typically described as a software bug.
Point-of-sale malware

MALICIOUS SOFTWARE USED TO TARGET POINT OF SALE AND PAYMENT TERMINALS
Pos malware
Point-of-sale malware (POS malware) is usually a type of malicious software (malware) that is used by cybercriminals to target point of sale (POS) and payment terminals with the intent to obtain credit card and debit card information, a card's track 1 or track 2 data and even the CVV code, by various man-in-the-middle attacks, that is the interception of the processing at the retail checkout point of sale system. The simplest, or most evasive, approach is RAM-scraping, accessing the system's memory and exporting the copied information via a remote access trojan (RAT) as this minimizes any software or hardware tampering, potentially leaving no footprints.

Malware

Malware (a portmanteau for malicious software) is any software intentionally designed to cause disruption to a computer, server, client, or computer network, leak private information, gain unauthorized access to information or systems, deprive access to information, or which unknowingly interferes with the user's computer security and privacy. Researchers tend to classify malware into one or more sub-types (i.e. computer viruses, worms, Trojan horses, ransomware, spyware, adware, rogue software, wiper and keyloggers).

Malware poses serious problems to individuals and businesses on the Internet. According to Symantec's 2018 Internet Security Threat Report (ISTR), malware variants number has increased to 669,947,865 in 2017, which is twice as many malware variants as in 2016. Cybercrime, which includes malware attacks as well as other crimes committed by computer, was predicted to cost the world economy $6 trillion USD in 2021, and is increasing at a rate of 15% per year. Since 2021, malware has been designed to target computer systems that run critical infrastructure such as the electricity distribution network.

The defense strategies against malware differ according to the type of malware but most can be thwarted by installing antivirus software, firewalls, applying regular patches to reduce zero-day attacks, securing networks from intrusion, having regular backups and isolating infected systems. Malware is now being designed to evade antivirus software detection algorithms.
