Attack summary

Severity: critical — Mantra Softech develops Aadhaar-enabled biometric devices and serves government, banking, and telecom clients across multiple countries. A breach of this company risks exposure of biometric authentication infrastructure data, government identity system integration details, and potentially large-scale PII or sensitive national security-relevant technical data — all of which qualify as regulated and highly sensitive.

The Osiris ransomware group claims to have compromised Mantra Softech India Pvt. Ltd. and has published data ('data_published' status), suggesting exfiltration of company data. The specific data types exfiltrated and whether encryption also occurred are not detailed in the post.

Disclosure context

About osiris

Osiris is a recently emerged ransomware group first observed in December 2025, operating with apparent financial motivations based on their targeting patterns and limited known victim base of three organizations. The group's origin and affiliations remain unclear due to their recent emergence, though their targeting of victims across the United States, India, and the Philippines suggests either a broad opportunistic approach or potential connections to actors operating across these regions. Limited intelligence is available regarding Osiris's specific attack methodology, encryption techniques, or whether they employ data exfiltration tactics prior to encryption, though their focus on manufacturing and technology sectors indicates they may be targeting organizations with valuable intellectual property or operational data. No major high-profile campaigns or significant ransoms have been publicly documented for this group, likely due to their recent emergence and small victim count. Given the December 2025 first observation date, Osiris appears to be a newly active threat actor, though insufficient data exists to determine their operational tempo, capabilities, or long-term threat potential. The group has been linked to 3 public disclosures across our corpus. First observed on a leak site on December 18, 2025; most recent post March 23, 2026. The operation is currently active.

If your organisation is affected

A listing by osiris means Mantra Softech Pvt appeared on a ransomware extortion site and data attributed to it has been published. If this is your organisation, or a supplier you depend on, the priority is to confirm the intrusion and contain it before the window to act closes.

Engage your incident-response team and preserve forensic evidence before remediating — do not wipe affected systems first.
Force a password reset and revoke active sessions for exposed accounts; rotate any credentials, API keys or certificates that may have been in the stolen data.
Assess regulatory notification duties (GDPR, NIS2, sector regulators) — many carry a 72-hour reporting clock from awareness.
Report the incident to your national CERT, CERT-In (India), as required for your jurisdiction.
Monitor for the data appearing on osiris's leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.
