Description

NightSpire is a financially motivated ransomware group that emerged in early 2025, targeting small to medium-sized enterprises across various sectors. The group employs a double extortion strategy, encrypting data after exfiltration, and has operated a Dark Web leak site to threaten the public release of stolen data since March 2025.

Key insights

  • Utilizes a double extortion model by encrypting stolen data and threatening public release.
  • Gains initial access using exploits like CVE-2024-55591, RDP brute-forcing, and phishing.
  • Features a custom ransomware payload written in Go that appends the '.nspire' extension to encrypted files.
  • Employs living-off-the-land techniques, leveraging legitimate tools for data exfiltration.
  • Targets a wide range of industries with ransom demands ranging from $150,000 to $2 million.
  • Rapidly advanced from operational immaturity to a robust operation with Ransomware-as-a-Service offerings.
