Attack summary

Severity: high — Acrisure is a large-scale insurance and financial services firm handling sensitive personal, business, and financial data for a significant share of U.S. businesses; the 'data_published' status indicates confirmed exfiltration and release, which elevates severity even absent detailed inventory, though lack of specifics prevents a critical rating.

The Payloadbin group has listed Acrisure (via domain capstoneins.com) with a disclosed status of data_published, implying exfiltration and publication of company data; however, no leak post content, ransom demand, or data size details were captured to confirm the precise nature or scope of the claimed attack.

Disclosure context

About Payloadbin

Payloadbin is a relatively obscure ransomware group that emerged in September 2021, primarily motivated by financial gain through extortion operations targeting diverse sectors across multiple countries. The group's origin and potential affiliations remain largely undocumented in public threat intelligence reporting, with limited information available regarding whether they operate as an independent entity or utilize a Ransomware-as-a-Service model. Based on observed victim patterns, Payloadbin has demonstrated a broad targeting approach without apparent sector specialization, though they have notably impacted healthcare, manufacturing, agriculture and food production, and telecommunications organizations across 48 documented cases. Their attack methodology and specific technical capabilities have not been extensively documented by major security research organizations, though their operational pattern suggests standard ransomware deployment tactics. The group has primarily targeted victims in the United States, Philippines, Australia, Mexico, and the United Kingdom, indicating either a broad opportunistic approach or potential linguistic capabilities spanning English-speaking regions and select international markets. No major high-profile campaigns, significant law enforcement disruptions, or notable ransomware payment records have been publicly attributed to this group by federal agencies or established threat intelligence firms. Current operational status remains unclear due to limited public documentation, though the group's relatively recent emergence and modest victim count suggests they may represent a smaller-scale operation compared to prominent ransomware families tracked by CISA and FBI reporting. The group has been linked to 48 public disclosures across our corpus. First observed on a leak site on September 9, 2021; most recent post March 26, 2026. The operation is currently active.

If your organisation is affected

A listing by Payloadbin means Capstoneins.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, CERT-MX (Mexico), as required for your jurisdiction.
Monitor for the data appearing on Payloadbin'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.
