Ransomware is a type of malware that encrypts files or systems and demands payment in exchange for restoring access.
Attackers gain initial access through phishing, credential abuse, or unpatched vulnerabilities, then spread laterally, disable backups, exfiltrate data, and deploy encryption payloads.
Ransomware can halt business operations, cause significant financial loss, expose sensitive data, and damage organizational trust, often requiring lengthy recovery efforts even after payment.
Nike announced it is investigating a potential data breach after a known ransomware group claimed to have leaked about 1.4 TB of internal business data online. While the company did not confirm ransom demands or the breach’s full scope, the incident highlights that even major global brands are at risk of ransomware-linked data exposure.
