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 8 public disclosures across our corpus. First observed on a leak site on February 25, 2026; most recent post May 21, 2026. The operation is currently active.

What the group claims

StarBucks Failed to reach out to us and didn't pay even $500,000 when we know they can afford it. It's not even that much we were asking for. Since you didn't contact is no negotiations and this is now in the hands of cybercriminals. This is a warning to all companies if you see yourself posted here to reach us. This is the only ammount we have on are servers due to migrating dmca and ignore abuse infrastructure. They were breached on 04/01/2026 and they know they were breached because they closed the s3 bucket starbucks-prod.
