# Disc Soft Addresses Daemon Tools Supply Chain Attack

In April 2026, Disc Soft, the developer of Daemon Tools Lite, responded to a widespread supply chain cyberattack that embedded backdoors into its software installers. The attack, attributed to a Chinese-speaking hacking group, affected thousands of users globally across government, industrial, scientific, manufacturing, and retail sectors in over 100 countries, including Russia, Belarus, Thailand, Germany, Spain, Turkey, and Brazil. Disc Soft is actively investigating and remediating the issue, urging users to update to the latest secure software version to mitigate risks.

- **Why this matters:** Government agencies and contractors relying on Daemon Tools software must assess exposure to this supply chain compromise and prioritize patching or replacing affected software to maintain cybersecurity integrity.
- Procurement professionals should consider enhanced vetting and monitoring of software supply chains to prevent similar attacks impacting critical operations.
- Cybersecurity vendors and service providers may find increased demand for supply chain risk assessments, incident response, and software integrity verification services.
- Organizations should incorporate this incident into their cybersecurity risk management and procurement strategies to address evolving supply chain threats.
