INC Ransomware Emerges as Major RaaS Threat in 2026 with 830+ Victims Since 2023

INC Ransomware has become a major RaaS threat, claiming over 830 victims since August 2023.

INC Ransomware has rapidly evolved into a significant RaaS threat, impacting over 830 organizations since August 2023, with US entities being the primary targets. The group leverages rewritten Rust-based encryptors for Windows and Linux/ESXi, and exploits vulnerabilities in public-facing applications for initial access, alongside credential dumping from Veeam backups. The emergence of related families like Lynx and Sinobi, sharing significant code overlap, indicates INC's growing influence in the RaaS ecosystem.

The lesson from this incident

Full lesson

INC Ransomware has become a major Ransomware-as-a-Service (RaaS) threat by targeting public-facing application vulnerabilities and extracting credentials stored in Veeam backup solutions — a critical misstep that turns recovery tools into attack vectors. The group's ability to rewrite encryptors in Rust for both Windows and Linux/ESXi environments demonstrates technical sophistication that bypasses many legacy defenses. With over 830 victims since 2023 and spawning related families like Lynx and Sinobi, INC illustrates how a single well-resourced RaaS operation can multiply its impact across the ecosystem. Organizations that fail to patch internet-facing applications promptly and secure backup infrastructure credentials are disproportionately exposed to this type of double-extortion ransomware campaign.
