Most modern smartphones do not need traditional antivirus programs, and such popups are advertisements from free apps, misleading websites, or ad networks.

How to Protect Against Ransomware: 13 Steps [2026]

Global ransomware attacks increased by 0.8% quarter-over-quarter in Q2 2026. The group Qilin has 279 confirmed victims, maintaining its position as the leading threat actor for four consecutive quarters. The rival group The Gentlemen saw a 62% increase in victims, reaching 269. Checkpoint Research's report indicates a shift in the ransomware landscape, challenging the narrative of declining attacks. IBM's analysis shows breaches within supply chains and third-party vendors have quadrupled over the past five years. Effective ransomware protection requires administrative access to endpoints, firewalls, and backup systems, along with specific software versions and tools. The 3-2-1-1-0 backup strategy is recommended, emphasizing offline, immutable backups. Organizations should implement multi-factor authentication (MFA) across all access points and actively patch known vulnerabilities. Network segmentation is crucial to limit ransomware spread, and canary files can provide early warnings of attacks. Regular phishing simulations and a well-documented incident response plan are essential for preparedness.
