ITSS Listed by everest Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
ITSS was listed by the everest Ransomware Group on 4 February 2025, indicating that internal files had been exfiltrated in a ransomware attack; the date of the intrusion itself has not been established. Individuals who may have had dealings with ITSS should review the company’s breach notice and any guidance on protective steps.
On 4 February 2025, the organisation ITSS appeared on a leak site operated by the ransomware group everest. The group claims it attacked the ITSS GLOBAL internal network and exfiltrated more than 173 GB of internal data. Public detail remains limited to that listing; the number of people affected is unknown and no independent confirmation of the intrusion has been published.
The claim matters because the group states the material includes internal and confidential banking information as well as contract information. For anyone whose details may sit inside those files, the practical question is what has been exposed and what steps reduce further risk.
Breaking down the breach
According to the everest listing, the ITSS GLOBAL internal network was attacked and more than 173 GB of internal important data were exfiltrated to the group’s servers. The listing names internal and confidential banking information and contract information among the material taken. The date of the intrusion itself is not disclosed; only the public listing date of 4 February 2025 is known. No statement from ITSS confirming or denying the claim has been included in the available record, and the total number of individuals whose data may be involved remains unknown.
The method of initial access, the duration of the intrusion, and whether ransomware encryption was also deployed are all undisclosed. The group’s post simply asserts that the data are now on its servers and urges a company representative to make contact “before time runs out.”
The group behind it: everest
Everest is a ransomware operation that has appeared on public leak sites for several years. Like many contemporary groups, it typically follows a double-extortion model: data are stolen before or during encryption, and the threat of public release is used to pressure victims into paying. Listings on its site are claims of successful intrusion and data theft; they are not independently verified statements of fact.
Public reporting on everest has described the group as opportunistic, targeting organisations across multiple sectors and geographies. It has previously posted sample files or file trees to demonstrate possession of data, though no such samples are referenced in the ITSS listing. The group’s communications are usually brief and transactional, focused on establishing contact rather than providing technical detail about how access was gained.
About ITSS
ITSS, also referred to in the listing as ITSS GLOBAL, is an organisation whose public web presence is associated with the domain itssglobal.com. Organisations of this type commonly operate in professional services, technology, or business-process domains and therefore maintain internal networks that hold financial records, contractual documents, and operational data. The precise industry classification and size of ITSS are not expanded upon in the breach record.
A breach of an organisation that handles banking and contract information is consequential because those categories of data can reveal payment details, commercial terms, and relationships with clients or partners. Even when the full scope of exposure is unconfirmed, the mere claim of such material being taken raises legitimate concern for anyone who has done business with the firm.
The information in question
The everest listing states that the exfiltrated material consists of “internal important data,” specifically including “internal and confidential banking information, as well as contract information.” No further inventory—file names, record counts, or data-subject categories—has been published. The total volume claimed is more than 173 GB.
Organisations that process banking and contractual material typically hold account identifiers, payment instructions, signed agreements, and related correspondence. Whether any of those specific elements are present in the claimed 173 GB remains unconfirmed. Public detail is limited to the group’s own description; no independent forensic summary has been released.
What's at stake
For individuals whose information may appear in banking or contract files, the concrete risks include potential misuse of financial identifiers, unsolicited contact that leverages knowledge of commercial relationships, and secondary fraud attempts that appear more credible because they reference real contracts. For the organisation itself, the stakes include operational disruption, possible regulatory scrutiny if personal data are involved, and the commercial impact of confidential terms becoming public.
Because the number of people affected is unknown and the exact contents are unconfirmed, the risk profile cannot yet be quantified. The prudent assumption is that any sensitive material that resided on the internal network could be among the files the group claims to hold.
Were you affected?
If you have had any financial, contractual, or employment relationship with ITSS or ITSS GLOBAL, treat the claim as a prompt to review your own exposure rather than as proof that your data are already circulating. Practical first steps include:
- Monitor bank and credit-card statements for unexpected activity and enable transaction alerts where available.
- Change passwords on any accounts that may have been used in correspondence with the organisation, and enable multi-factor authentication.
- Be cautious of unsolicited emails or calls that reference contracts or banking details; verify any such contact through known official channels.
- Request a free credit report or equivalent monitoring service if you believe financial identifiers could be involved.
- Run a free exposure scan of your email address against known breach data sets to check whether your address has already appeared in other incidents.
Public information about this incident remains limited to the everest listing of 4 February 2025. Further clarity will depend on any official statement ITSS may issue and on whether the claimed data are ultimately released or confirmed by independent researchers.

Publicly posted by everest — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
