high severity March 21, 2023 · 3 min read Unverified claim — what this is

siebold.com Listed by abyss Ransomware Group

If you are a customer of siebold.com, here’s what is being claimed, and what it would mean for you.

The Siebold Company, Inc. 700Gb uncompressed data

— from Abyss’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
siebold.com Listed by abyss Ransomware Group

On March 21, 2023, The Siebold Company, Inc. appeared on the leak site operated by the abyss Ransomware Group. The listing states that the Michigan-based firm suffered a ransomware attack in which attackers exfiltrated 700Gb of uncompressed internal files. The disclosure does not specify the exact number of people affected or list the precise data types contained in the archive.

Details from the Leak-Site Listing

The primary source, hosted on the abyss leak site and indexed by ransomware.live, states that Siebold.com was listed following a ransomware deployment. It explicitly notes 700Gb uncompressed data and describes the material as “internal files exfiltrated in ransomware attack.” No sample files are shown in the public listing, and the disclosure does not quantify how many customer, employee, or vendor records may be inside the archive. The exact date of initial compromise also remains unknown from the published information.

Why This Matters for You and Your Family

When a company that handles personal information suffers a breach, the consequences reach far beyond corporate walls. If your name, address, date of birth, Social Security number, medical details, or financial records were stored in Siebold’s systems, they may now sit on a criminal server. Even when record counts are not published, the volume—700 GB—suggests the archive likely contains information that can be used for identity theft, tax fraud, or targeted phishing against you and your family. Ordinary people who interacted with the company as customers, patients, or employees now face months or years of heightened risk.

The Doxxing and Identity-Chain Implications

Stolen internal files frequently include spreadsheets that link names to email addresses, phone numbers, dates of birth, and sometimes passwords or security-question answers. Attackers and data brokers can chain these pieces together with information from other breaches to build detailed profiles. A single leaked work email can lead to personal accounts, social-media handles, and even children’s gaming usernames that share the same password or recovery phone number. Once the chain begins, doxxing escalates quickly: public records, family addresses, and photographs can be assembled and sold or published to increase pressure or enable further crimes. Credential leaks like this one cascade into account takeovers that affect not only corporate logins but also home networks and children’s online identities.

Abyss Ransomware Group Track Record

Public reporting attributes the emergence of abyss to late 2022. The group has targeted organizations across North America and Europe, typically gaining initial access through phishing, remote-desktop protocol brute-force, or exploited vulnerabilities in internet-facing services. After establishing a foothold, operators exfiltrate data before deploying ransomware. They then follow a double-extortion model: demand payment for decryption and threaten to publish stolen files if the victim refuses. Notable prior victims listed on their leak site include manufacturing, healthcare, and professional-services firms. The group’s playbook relies on volume and speed—listing victims within weeks of encryption and gradually releasing proof packets to create urgency.

What to do

  • Run a DoxxScan to map every link between your handles, emails, phone numbers, and real identity, then use the cleanup of Warden to remove what you can control.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure that touches you or your family is caught in hours rather than months.
  • Rotate any password you used at Siebold.com or any related service, replace it with a unique passphrase everywhere it was reused, and enable 2FA through an authenticator app instead of SMS.
  • Cover the household with DoxxScan family coverage that extends to dependents and children’s gaming accounts, which often chain back to the same address or recovery email exposed in corporate breaches.
  • Let remediation specialists handle takedown requests across data brokers and extortion sites while you focus on securing your own devices and accounts.

The breach of Siebold Company demonstrates once again that ransomware operators move quickly from encryption to public shaming, leaving ordinary families to manage the long-term exposure. Staying ahead requires more than reactive checks; it demands continuous visibility and expert assistance. DoxxScan by GalaxyWarden delivers exactly that through continuous monitoring across 13.1 billion+ breach records and more than 100 platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts. One decisive step today can break the chain before the next leak appears.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
