ISOR Listed by Cicada3301 Ransomware Group

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

Isor was listed on Cicada3301's leak site. Cicada3301 claims to have stolen internal data. This is the group's claim, not a confirmed finding.

ISOR Listed by Cicada3301 Ransomware Group

On January 3, 2025, the ransomware group Cicada3301 added ISOR to its leak site and began a countdown timer that currently shows 29 days remaining. The posting claims the company’s internal files, totaling 1,600 GB, were exfiltrated during a ransomware attack.

Already exposed?

You can’t unleak data. You can take away what it’s worth.

A leaked record is where it starts, not where it ends. What turns it into your front door is the look-up sites publishing your address beside your name — and those are what an AI reads when somebody asks about you. The free scan shows you both. We write to 580 companies.

What Public Reporting Shows

Public reporting indicates that ISOR, a provider of outsourced radiology and teleradiology services, is the latest victim listed by Cicada3301. The leak site entry includes a status counter showing 29d 22h 21m 59s and lists the volume of stolen data as 1,600 GB of internal files. No sample data has been published yet, and the precise number of individuals whose records are contained in the archive remains unknown. Available reporting describes the incident as a classic ransomware double-extortion attempt in which the attackers first encrypt systems and then threaten to release the stolen information unless a ransom is paid.

Why This Matters for You and Your Family

Medical imaging companies like ISOR routinely handle names, dates of birth, Social Security numbers, addresses, insurance details, and clinical images for thousands of patients. If that information reaches the public dark-web markets, it can be used for identity theft, insurance fraud, or targeted phishing against you or your children. Medical data sells for a premium because it combines sensitive personal identifiers with details that make social-engineering attacks far more convincing. Even if you never directly used ISOR, your information may have been shared by a referring physician, hospital, or insurer, meaning the breach could affect your family without your knowledge.

The Doxxing and Identity-Chain Implications

Credential leaks and internal documents from healthcare providers often contain employee and patient email addresses, usernames, and password hints. These pieces quickly link to gaming accounts, social-media handles, and home addresses. Once attackers map one credential to a real person, they can pivot to take over connected accounts, including your children’s gaming profiles that frequently reuse the same email or password. The result is a doxxing chain that can expose your home address, phone number, and family relationships within hours of the data appearing on underground forums.

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.

Editorial & sourcing policy

GalaxyWarden is a breach-monitoring service and news aggregator. We do not exfiltrate, host, purchase, or redistribute stolen data. Breach information is compiled from publicly accessible sources and threat-intelligence platforms, and is reported as claims attributed to their source. We promptly correct or remove material shown to be inaccurate — see our content & takedown policy or write to support@galaxywarden.com.
