Disclosure context

About ShadowByt3$

ShadowByt3$ is an emerging ransomware group that was first observed in February 2026, appearing to be financially motivated based on its ransomware operations. The group's country of origin and any potential affiliations with other cybercriminal organizations remain unknown due to limited intelligence available on this newly identified threat actor. Given the minimal public documentation available, the group's attack methodology, tools, and operational tactics have not been sufficiently analyzed or reported by major cybersecurity firms or government agencies. No notable campaigns, high-profile victims, or significant ransoms have been publicly documented by CISA, FBI, Mandiant, or other reputable security researchers, with only one known victim reported to date and no specific sector targeting patterns identified. The current operational status of ShadowByt3$ remains unclear due to the limited intelligence available on this recently emerged and relatively unknown ransomware operation. The group has been linked to 21 public disclosures across our corpus. First observed on a leak site on February 25, 2026; most recent post August 25, 2026. The operation is currently active.

If your organisation is affected

A listing by ShadowByt3$ means A-Plus Software Limited 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, NCSC (United Kingdom), as required for your jurisdiction.
Monitor for the data appearing on ShadowByt3$'s leak site and across paste and breach channels, and brief downstream partners who may be exposed through you.

How we know this. Darkfield monitors public ransomware leak sites continuously, archiving every new disclosure and the data later released against the victim. Each entry on this page is sourced from the operator's own publication and cross-checked against complementary OSINT feeds (RansomLook, ransomware.live, RansomWatch). We do not collect or host stolen data — only the metadata, timestamps and screenshots needed to make the public disclosure searchable and accountable. Records here are corrected when the original post is edited, retracted, or merged with another disclosure.
