Attacks and malware
What is Malware?
Software written to act against the interests of the machine's owner.
Malware is software written to act against the interests of the owner of the machine it runs on. The term covers many families with different jobs: loaders, droppers, remote access trojans, infostealers, ransomware, wipers, rootkits and more.
Analysts classify malware by what it does rather than how it spreads, because the function tells you what the attacker wanted and what to look for next. A stealer means credential theft, a loader means something else is coming.
