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.

Attackers targeted Salesforce data

Public reporting indicates the threat actor known as Icarus first compromised Klue’s systems and then exfiltrated information from the Salesforce environments of companies that had integrated with the competitor-intelligence platform. Among the newly disclosed victims are AlertMedia, Blackbaud, Camunda, and additional organizations that have begun notifying people whose records were taken. The attackers reportedly threatened to publish the stolen data. Available reporting describes the breach as a supply-chain incident in which one company’s compromise exposed contact and support details held by its customers.

Types of personal data exposed

This incident matters because the records involved often include names, email addresses, phone numbers, employer information, and notes that support and sales teams keep about customers and prospects. If your data was among the exposed records, it can be used to target you with phishing, identity theft attempts, or more sophisticated social engineering. For your family, the risk is personal: an email or phone number linked to a parent can lead to attacks on shared accounts, children’s school-related logins, or family gaming profiles that reuse the same credentials.

How one breach leads to doxxing

The doxxing and identity-chain implications are significant. Once a single breach exposes an email or phone, attackers can cross-reference it against dozens of other leaks to build a complete profile. A business contact record that lists your work email can be chained to personal accounts, home addresses, and even children’s usernames on gaming platforms. Credential leaks like this one frequently cascade into account takeovers, where one reused password grants access to email, then banking, then family-shared services. The result is a widening chain of exposure that can end in full doxxing of household members.

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.
