tecnoabi.com Listed by M3rx Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On August 14, 2026, the ransomware group M3rx listed Tecnologías de Código Abierto S.L., which trades as Tecnoabi and operates the site tecnoabi.com, on its leak site. The listing is an unverified accusation from the group. As of writing, the company has not publicly confirmed that an incident occurred, that systems were accessed, or that any data left its control.

Public detail is limited to what appears on that listing and to open information about the firm. No independent confirmation from the company, a regulator, or a breach index is reflected in the available record. For customers, partners, and others who deal with a B2B software provider, the practical question is what a leak-site claim does and does not establish, and what cautious steps make sense if the claim later proves partly or wholly accurate.

What is being claimed

M3rx has listed tecnoabi.com on its leak site and, according to the listing, associates the entry with a claimed volume of about 300 GB and 63,434 files. The group’s materials do not, in the facts provided, describe how access was supposedly obtained, when any intrusion allegedly began or ended, or which systems were involved. The number of people affected is unknown. Specific categories of personal or business data are not disclosed in the listing summary available here.

A leak-site entry is a pressure tactic common in ransomware and extortion activity. It is not the same as a verified breach notification. Listings can exaggerate scale, recycle older material, or misattribute data. Until the company or another authoritative source confirms or denies the claims, the responsible framing is that M3rx asserts Tecnoabi was compromised and that a large file set is held for leverage—not that those assertions have been proven.

Who is M3rx?

M3rx is known publicly as a ransomware and data-extortion actor that operates in the style of groups that encrypt or exfiltrate data and then threaten publication on a dedicated leak site if demands are not met. Like other crews in this category, it typically relies on public naming of victims, countdown-style pressure, and claims about file volume to increase urgency for the targeted organisation and its counterparties.

Well-documented patterns for such groups include opportunistic or targeted intrusion, attempts to move laterally inside networks, and the use of stolen data as bargaining material whether or not encryption was successful. None of that general background proves what happened in this specific case. For Tecnoabi, the only incident-specific statements that can be repeated from the record are those tied to the listing itself: that M3rx named the firm and claimed roughly 300 GB and 63,434 files. Anything beyond that about method, dwell time, or exact contents remains undisclosed in the facts given.

Who is tecnoabi.com?

Tecnologías de Código Abierto S.L., trading as Tecnoabi, is described in public company information as a Málaga, Spain-based B2B software development firm registered in 2008. It is associated with Málaga TechPark and presents expertise in Java, .NET, and proprietary products such as VirtRoom and CMMS-oriented software, with a focus that includes after-sales management systems. It is also identified as an official Google Play developer. Its public face is the website tecnoabi.com.

Firms in this sector typically sit between their own internal operations and the systems of business clients. That position can make a claimed incident consequential even when nothing is confirmed: software vendors may hold source code, configuration material, project documentation, support tickets, credentials used in delivery, and commercial records. A listing against such a company matters to partners and end customers because trust in the supply chain depends on whether client-related material could have been among any files an attacker claims to hold—again, only if the claim is accurate.

What was likely exposed

The facts state that data types named as exposed are not disclosed. M3rx’s listing claims a volume of 300 GB and 63,434 files, but that figure is the group’s assertion, not an audited inventory. It is not established which systems, if any, were copied, or whether the material is current, complete, or relevant to third parties.

If files were taken from a B2B software and after-sales systems provider of this kind, organisations in the sector typically hold some mix of the following—presented here only as sector-typical possibilities, not as confirmed contents of any Tecnoabi archive:

• Business contact and contract information for clients and suppliers
• Project documentation, tickets, and after-sales or CMMS-related operational records
• Source code, build artefacts, or configuration related to delivered products
• Internal employee and administrative records
• Credentials, certificates, or integration details used to deliver or support software

None of those categories should be read as a finding that they appear in M3rx’s claimed set. Exact contents remain unconfirmed. People affected, if any, are unknown.

Why it matters

For individuals and businesses that have worked with Tecnoabi, the risk is conditional. If client or partner files were among material an extortion group claims to hold, possible outcomes include unwanted contact, social engineering that references real projects, exposure of commercial terms, or misuse of technical details that make follow-on fraud easier. If only internal material were involved, direct harm to outsiders might be lower, but supply-chain confidence can still be affected while uncertainty lasts.

For the organisation named on the listing, the immediate stakes are reputational and operational: responding to customer questions, assessing whether the claim is genuine, and deciding what, if anything, to notify under applicable law. A leak-site post does not by itself prove negligence, successful exfiltration, or the accuracy of the stated file count. It does establish that a known extortion brand has chosen to name this firm publicly, which is enough to warrant careful monitoring and measured precautions by people who share email addresses, contracts, or system access with the company.

Because people affected are unknown and data types are undisclosed, broad assumptions that “everyone’s data is out” are not supported. The useful stance is preparedness without treating the attacker’s marketing as a verified breach report.

What to do now

Treat the situation as an unverified claim unless Tecnoabi or an official authority confirms otherwise. If you are a client, partner, or employee who has shared information with the firm, practical steps remain conditional on the possibility that related data could surface:

• Be alert for phishing or calls that reference Tecnoabi projects, invoices, or support history; verify requests through known channels
• If you reuse passwords on related accounts, change them and enable multi-factor authentication where available
• Watch financial and business accounts for unusual activity if you exchanged payment or banking details
• Prefer official company notices over screenshots or third-party summaries of leak sites
• Document any suspicious contact that appears to rely on insider knowledge of your work with the firm

Readers can also run a free exposure scan of their email address to check whether that address has already appeared in other known breach datasets. Such a scan does not prove or disprove M3rx’s specific claims about Tecnoabi, but it can show whether the same address is already circulating from unrelated incidents and help prioritise password and account hygiene while public confirmation remains absent.
