CONEX Listed by nokoyawa Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On 20 January 2023, the ransomware group known as nokoyawa listed CONEX on its leak site, claiming to have carried out an attack that involved the exfiltration of internal files. The number of people affected remains unknown, and public detail about the precise scope of the incident is limited. For customers, partners, and anyone whose information may sit inside CONEX systems, the listing raises immediate practical questions about what data left the company’s control and what steps are now warranted.

CONEX specialises in customs-procedure management software. A breach involving a firm that handles declarations and interconnections with customs administrations can touch commercial, logistical, and personal data tied to cross-border trade. Until fuller confirmation emerges, those potentially exposed are left to weigh the group’s claim against the limited facts that have been reported.

Breaking down the breach

According to the available record, CONEX was listed by the nokoyawa ransomware group on 20 January 2023. The report states that internal files were exfiltrated in a ransomware attack. No figure has been given for the number of people affected, no inventory of specific file types beyond the general description of internal files has been published, and the exact method of initial access or the duration of the intrusion has not been disclosed in the public summary.

Ransomware incidents of this kind typically combine encryption of systems with the theft of data intended for leverage. In this case the public account states only that the group claimed an exfiltration of internal files and posted the organisation on its leak site. Whether negotiations occurred, whether a ransom was paid, or whether any data was subsequently released remains unconfirmed in the material provided. The scale of the event, measured either in records or in systems impacted, is likewise unknown.

Inside nokoyawa

Nokoyawa is a ransomware operation that became active in the public eye around early 2022. Like many contemporaneous groups, it has been observed using a double-extortion model: encrypting victim environments while also copying data and threatening to publish it if payment is not made. The group has historically targeted a range of sectors rather than specialising in a single industry, and its leak site has served as the primary channel for naming alleged victims and, in some cases, releasing sample files.

Public reporting on nokoyawa has described the use of common initial-access vectors seen across the ransomware ecosystem, including exploitation of exposed remote services and stolen credentials, though the precise vector used against any individual organisation is rarely confirmed by the group itself. Affiliates or operators associated with the brand have posted victims across multiple countries. In the present matter, the sole attribution rests on the group’s own listing of CONEX; that listing constitutes a claim rather than an independently verified finding, and no further statements by the group about this specific victim appear in the reported facts.

Who is CONEX?

CONEX describes itself as a specialist in customs-procedure management software. Its SaaS platform is presented as a complete and modular system dedicated to the treatment of all types of declarations, covering interconnection needs with customs administrations. In practical terms, organisations of this kind sit at the junction of logistics, trade compliance, and regulatory reporting. They routinely process data belonging to importers, exporters, freight forwarders, and related service providers.

Because customs declarations and related filings often contain commercial invoices, shipment details, company identifiers, and sometimes personal data of responsible individuals, a compromise at a software provider in this niche can have downstream effects well beyond the provider’s own staff. The consequential nature of such a breach stems less from the size of the software firm itself and more from the sensitivity and breadth of the information that flows through its platform in the ordinary course of business.

The information in question

The reported facts state only that internal files were exfiltrated in the ransomware attack. No further breakdown of data types—such as customer databases, declaration records, credentials, or employee information—has been supplied. The number of individuals or organisations whose data may have been included is unknown.

Firms that supply customs-management SaaS typically hold configuration data, user accounts, historical declaration files, and correspondence with clients and authorities. Whether any of those categories were among the files taken in this incident has not been confirmed. Readers should therefore treat the contents of the stolen material as unconfirmed; the public record does not establish precisely what left CONEX’s environment.

What's at stake

For individuals and companies whose information may have been present, the concrete risks include potential misuse of commercial or personal details for fraud, competitive intelligence, or further social-engineering attempts. Customs-related records can reveal supply-chain relationships, pricing, and shipment patterns that are valuable to opportunistic actors even if they are not immediately “identity-theft” material in the classic sense.

For CONEX itself, the incident carries operational, contractual, and reputational consequences. Customers may demand assurances about containment, notification obligations under applicable data-protection regimes may be triggered once the scope is better understood, and the organisation must contend with the possibility that stolen files could surface later. Because the number of people affected remains unknown and the exact data types are undisclosed, the full perimeter of harm cannot yet be drawn; the prudent assumption is that any internal file of potential sensitivity should be regarded as at risk until proven otherwise.

If your data was in this claimed breach

If you have a relationship with CONEX—whether as a customer, partner, or employee—begin by monitoring official communications from the company for any confirmation or guidance. Review account activity on related platforms, enable multi-factor authentication where it is not already in place, and treat unsolicited messages that reference customs filings or shipments with heightened caution. Consider placing fraud alerts with relevant credit or commercial monitoring services if you believe personal or financial identifiers could have been involved.

Because public detail on this incident is limited, you may also wish to check whether your email address has appeared in other known breach data sets. Free exposure-scan tools can indicate whether an address has surfaced in previously compiled collections, giving a broader picture of your existing exposure even when the precise contents of a single incident remain unconfirmed.
