Attack summary

Severity: high — Confirmed exfiltration of production data from a major multinational corporation with significant operational and customer-facing infrastructure. S3 bucket compromise typically exposes sensitive business and potentially customer data at scale, even without detailed enumeration in the post.

The group shadowbyt3$ claims to have breached Starbucks on 04/01/2026 and exfiltrated data from a production S3 bucket (starbucks-prod). The attacker alleges the company failed to negotiate after a $500,000 ransom demand, leading to publication of the stolen data.

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.

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 13 public disclosures across our corpus. First observed on a leak site on February 25, 2026; most recent post June 16, 2026. The operation is currently active.

If your organisation is affected

A listing by ShadowByt3$ means StarBucks Company (StarBucks.com 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, CISA (United States), 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.
