Malware is software that’s designed to harm, exploit or compromise devices and systems. Threat actors use malware to steal data, extort ransom, disrupt operations and gain unauthorized access. Malware comes in many forms, ranging from minor annoyances to serious security threats like viruses and worms.

The first example of malware was a computer virus called Elk Cloner that spread through Apple ll computers in 1982. It was a piece of programming code created by a 15-year old as a joke, but it fit the definition of malware: unwanted intrusions that cause problems and can’t be easily undone.

Detecting malware threats requires a mix of technology tools and tactics. For example, implementing firewalls, intrusion detection/prevention systems and regular backups minimizes the impact of malware attacks. In addition, identifying indicators of compromise (IOCs) during and after a malware incident helps direct response efforts and improve protections.

Some examples of malware signs to watch for include a loss of disk space, suspicious email attachments and erratic internet activity that doesn’t correlate with user behavior. Other symptoms might be an unexpected swell in network activity or new programs that weren’t installed by the user.

Infected systems need to be disconnected from the internet and run a full system scan using reliable antivirus/antimalware software. If any files have been damaged or corrupted by malware, the infected machine may need to be wiped and restored from a clean backup. Afterward, the system should be monitored for abnormal activity and patched or updated as needed to close vulnerabilities.
