Ransomware is a type of malicious software that encrypts a victim's files, making them inaccessible, and then demands a ransom payment, typically in cryptocurrency, in exchange for the decryption key needed to restore access.
Attackers commonly gain initial access through phishing emails, unpatched software vulnerabilities, or exposed remote access systems, then spread across a network to encrypt as many files and systems as possible before revealing the ransom demand.

Why Paying the Ransom Is Widely Discouraged
Security agencies and law enforcement generally discourage paying the ransom, since payment doesn't guarantee attackers will actually provide a working decryption key, and it also directly funds further criminal activity.
The most reliable defense against ransomware is maintaining regular, isolated backups that aren't accessible from the main network, alongside timely software updates and security awareness training, so an organization can restore its systems without needing to pay attackers at all.
