100X and ALL Clients Listed by ransomhouse Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On April 30, 2023, the ransomware group known as ransomhouse listed 100X, a Miami-headquartered information technology consulting and software development firm, on its leak site, claiming the company and all of its clients had been affected. Public reporting states that internal files were exfiltrated in a ransomware attack. The number of people affected remains unknown, and further operational details have not been disclosed.

Because 100X serves clients across industries and geographies, including work tied to cloud workspaces and aviation, a claim of this kind raises practical concerns for the firm’s customers and anyone whose information may have been held in its systems. What follows is limited to confirmed reporting and established public context; where specifics are absent, they are stated as such.

Breaking down the breach

According to the available record, ransomhouse publicly listed 100X and asserted that the firm and all of its clients were implicated. The reported date associated with this disclosure is April 30, 2023. The only data description provided is that internal files were allegedly exfiltrated in a ransomware attack. No confirmed figure for individuals affected has been published, nor have details been released about the initial access method, the duration of any intrusion, encryption of systems, ransom demands, or whether negotiations occurred.

The leak-site listing itself constitutes a claim by the group rather than independent verification. Organizations named in such postings sometimes confirm incidents later, sometimes dispute elements of the claim, and sometimes remain silent; in this case, public detail beyond the listing and the description of exfiltrated internal files is limited. Scale, exact file inventories, and client-by-client impact are undisclosed.

Inside ransomhouse

Ransomhouse is a known ransomware operation that has appeared in public threat reporting through victim listings on dedicated leak sites. Like other groups in this category, it has been associated with double-extortion style activity: data is taken from a victim environment and the threat of publication is used alongside, or instead of, system encryption to pressure payment. The group has presented itself in ways that emphasize collaboration among affiliates or partners rather than a single monolithic crew, a pattern seen across several modern ransomware brands.

Typical publicly documented tactics for actors in this space include exploitation of remote access services, stolen credentials, or unpatched internet-facing systems, followed by lateral movement, data staging, and exfiltration before any ransom note appears. Ransomhouse listings generally name the organization and sometimes assert broad impact on customers or partners; those assertions remain claims until corroborated. Nothing in the public facts for this incident attributes specific technical indicators, ransom amounts, or unique statements by the group beyond the listing of 100X and its clients and the reference to exfiltrated internal files.

Who is 100X?

100X is described as an established full-service information technology consulting and software development firm, founded in 2009 and headquartered in Miami, Florida. Its stated focus includes “Anytime/Everywhere” cloud workspace solutions and work connected to the aviation industry. Although based in South Florida, it reports serving clients worldwide across various industries. The firm’s own public-facing description emphasizes long-term client relationships, service performance, and support for customer growth.

Firms of this type commonly design, deploy, and support cloud environments, business applications, and industry-specific systems. They often hold administrative access, configuration data, credentials, project documentation, and business information belonging to the organizations they serve. A breach involving an IT consultancy can therefore extend beyond the consultancy’s own staff to the operational and commercial data of its clients, which is why a listing that explicitly references “all clients” draws attention even when technical particulars remain sparse.

What was likely exposed

The facts name exposed material only as internal files exfiltrated in a ransomware attack. No inventory of file types, no record counts, and no confirmation of specific categories such as personal identifiers, financial records, source code, or client credentials have been published in the material provided. Exact contents are therefore unconfirmed.

Organizations in IT consulting and cloud workspace services typically maintain internal documents that can include contracts, network or system diagrams, employee and contractor information, client contact lists, project files, support tickets, and credentials or configuration data used to manage customer environments. Aviation-related work may involve additional operational or compliance documentation. Any of these categories could theoretically appear among “internal files,” but it would be inaccurate to state that particular data types were exposed in this incident when they have not been named. Readers should treat the scope as unresolved pending further disclosure from the company or independent analysis of any leaked material.

Why it matters

For individuals and organizations connected to 100X, the primary risks are secondary misuse of any data that may have left the environment: targeted phishing that references real projects or contacts, credential stuffing if passwords or keys were present, or competitive and contractual harm if business documents were taken. Clients in regulated or safety-sensitive sectors, including aviation-related operations, may face additional compliance and operational review obligations even when the precise data set is unknown.

For 100X itself, a public ransomware listing can affect client trust, contractual relationships, and the need to support customer incident response. Because the firm positions itself as a long-term technology partner with broad access to client environments, the unverified claim that “all clients” were implicated increases the practical burden of notification, investigation, and remediation whether or not every client system was directly touched. The absence of a published affected-person count does not reduce the need for careful verification by those who do business with the firm.

What to do if you're exposed

If you are a client, employee, or partner of 100X, contact the firm through known official channels to ask what, if anything, has been confirmed about your data and what steps it is taking. Monitor accounts for unusual login attempts, enable multi-factor authentication where available, and treat unexpected messages that reference the company or your projects with caution. Consider placing fraud alerts with major credit bureaus if you believe personal financial identifiers could have been involved, and review statements for unfamiliar activity.

Because public detail on this incident remains limited, verifying whether your own email address has appeared in known breach data sets is a sensible additional check. Readers can run a free exposure scan of their email to see whether their information has surfaced in documented breaches and then prioritize password changes and monitoring accordingly.
