Slimsoft Listed by Space Bears Ransomware Group

On December 4, 2025, Israeli software developer Slimsoft appeared on the leak site of the spacebears ransomware group. The company, which builds custom software and websites for clients, is claimed to have had internal files exfiltrated after a ransomware attack. While the exact number of people affected remains unknown, anyone whose personal or financial information was stored in Slimsoft’s systems could now have that data circulating among criminals.

What Public Reporting Shows

Public reporting indicates the incident involved the theft of internal documents from Slimsoft’s network. The company, based in Israel and operating for more than 25 years, specializes in custom software development and website creation. The data taken includes files that may contain client records, project details, and other sensitive business information. The spacebears group posted proof of the breach on their dark-web leak site, giving Slimsoft a deadline to pay or face full public release of the stolen material. SQL databases were among the systems listed as compromised.

Why This Matters for You and Your Family

When a company that builds software for others is breached, the ripple effects reach ordinary customers like you. If you or your family ever hired Slimsoft to create a website, manage an online store, or develop an application, your contact details, payment records, or project specifications may have been inside the stolen files. Criminals routinely search these dumps for email addresses, phone numbers, and passwords that can be used to break into personal accounts. A single leak like this can expose your family’s information without you ever knowing the company held it.

The Doxxing and Identity-Chain Risks

Stolen internal files often contain more than just names and emails. They can include notes that link your work email to a personal phone number, a home address, or even details about your children. Attackers use these connections to build an identity chain — mapping your online handles to your real life. Once they have that map, they can move from one account to another, turning a corporate breach into personal doxxing. Credential leaks like this one frequently cascade into gaming account takeovers, especially when parents reuse passwords across work projects and family gaming profiles.

Spacebears Group Track Record

Public reporting attributes the attack to the spacebears ransomware group. The group emerged in recent years and has targeted organizations across multiple countries with a straightforward extortion playbook: gain initial access, exfiltrate sensitive files, encrypt systems, then demand payment while threatening to publish the stolen data on their leak site. Notable prior victims include other mid-sized service companies whose client data ended up exposed when ransom demands went unmet. Their approach relies on the fear of reputational damage and identity theft rather than highly sophisticated malware.

What to do

• Run a DoxxScan to map every link between your emails, phone numbers, usernames, and real identity so you can see exactly what this claimed breach may have exposed.
• Rotate any password you used at Slimsoft or on any site it developed for you, then enable 2FA through an authenticator app instead of text messages.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours, not months.
• Cover the household with DoxxScan family protection that extends to your children’s gaming accounts, which often chain back to the same addresses and credentials targeted in incidents like this.
• Let remediation specialists handle takedown requests across data brokers and exposed records while you focus on securing your own accounts.

The most effective defense is early visibility and rapid action before criminals can connect the dots. Start your DoxxScan trial today and use its continuous monitoring, AI-powered identity-chain mapping, and hands-on remediation by specialists to protect yourself and your family — including gaming accounts that are increasingly caught in these breach cascades. Do not wait for the next leak site posting.
