dismogas Listed by stormous Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Ransomware groups continue to target organisations across Latin America, using double-extortion tactics that combine system encryption with the threat of public data leaks. Listings on criminal leak sites have become a routine feature of this landscape, often appearing before any independent confirmation of the underlying incident. The appearance of dismogas on such a site in early March 2024 fits this pattern and warrants careful examination of what is actually known.

On 4 March 2024, the ransomware group stormous listed dismogas, a Colombian organisation, claiming to have conducted a ransomware attack that involved the exfiltration of internal files. The number of people affected remains unknown, and public detail beyond the listing itself is limited. For customers, employees and partners of organisations in the energy and utilities sector, any such claim raises legitimate questions about the security of operational and personal information.

Inside the incident

According to the available record, dismogas was listed by the stormous ransomware group on 4 March 2024. The group claims the attack involved the exfiltration of internal files. No further technical details—such as the initial access vector, the duration of the intrusion, the volume of data taken, or whether systems were encrypted—have been publicly disclosed. The number of individuals whose information may have been involved is recorded as unknown. Independent confirmation of the claim has not been reported in the material available for this account, so the listing itself remains an unverified assertion by the threat actor.

In the absence of statements from dismogas or Colombian authorities detailing the event, the precise timeline and scope stay unconfirmed. What is documented is simply the date of the listing and the assertion that internal files were removed during a ransomware operation.

Who is stormous?

Stormous is a ransomware operation that has been observed conducting double-extortion campaigns: encrypting victim systems while simultaneously stealing data and threatening to publish it on a dedicated leak site if a ransom is not paid. Like many contemporary groups, it maintains a public-facing site where it posts victim names and, in some cases, samples of stolen material to increase pressure. Public reporting has associated the group with opportunistic targeting across multiple sectors and geographies rather than a narrow focus on any single industry.

In this instance, the group claims to have compromised dismogas and exfiltrated internal files. No additional statements attributed specifically to stormous about this victim—such as ransom demands, file counts, or sample releases—appear in the documented facts. The listing should therefore be treated as the group’s claim rather than established fact until corroborated by the organisation or independent investigators.

About dismogas

Dismogas is a Colombian organisation operating in a sector that typically involves the distribution or management of gas and related energy services. Companies of this type routinely handle operational records, customer account information, billing data, employee records, supplier contracts and technical documentation related to infrastructure. Because energy and utilities providers sit at the intersection of critical infrastructure and large customer bases, any compromise of their systems can affect both service continuity and the privacy of individuals who rely on those services.

A ransomware incident involving such an organisation is consequential for two reasons. First, internal files may contain commercially sensitive or operationally critical material. Second, the same files frequently include personal data belonging to customers and staff. Even when the exact contents remain unconfirmed, the mere possibility of exposure creates lasting concern for those whose details may have been held by the company.

The information in question

The facts state that internal files were exfiltrated in a ransomware attack. No more granular inventory—such as customer databases, employee records, financial documents or technical schematics—has been publicly named. Organisations in the gas and energy distribution sector typically retain a mixture of personal identifiers, contact details, account histories, payment information, employment records and operational data. Whether any or all of these categories were among the files claimed by stormous is unconfirmed.

Because the precise contents have not been disclosed, it is not possible to state with certainty what specific data types left the organisation’s control. Readers should treat any detailed description of the stolen material as speculative until official confirmation is provided.

The real-world impact

For individuals whose information may have been among the internal files, the primary risks are identity misuse, targeted phishing and unsolicited contact that leverages knowledge of their relationship with the company. Even limited internal documents can contain enough context for fraudsters to craft convincing messages. Employees face similar exposure if personnel files or internal communications were taken.

For dismogas itself, the consequences include potential regulatory scrutiny under Colombian data-protection rules, the cost of investigation and remediation, reputational damage, and possible disruption to operations if systems were encrypted. Because the scale of the incident remains unknown, the full extent of these effects cannot yet be measured. Customers and partners may also experience secondary impacts if service interruptions or heightened verification procedures follow the event.

None of these outcomes is automatic; they depend on what was actually taken and how the organisation responds. The absence of confirmed numbers simply means the risk cannot be quantified with precision at present.

Were you affected?

If you are a customer, employee or partner of dismogas, treat the listing as a prompt to review your own exposure rather than as proof that your data has already been misused. Monitor financial statements and account activity for unusual transactions. Be cautious of unexpected emails, calls or messages that reference your relationship with the company or request personal details. Consider changing passwords associated with any accounts linked to the organisation, especially if the same credentials are reused elsewhere. Enable multi-factor authentication wherever it is available.

You can also run a free exposure scan of your email address to check whether it has appeared in known breach data sets. Such checks do not confirm involvement in this specific incident, but they provide a practical starting point for understanding whether your information has already circulated in other compromises. Stay alert for any official notification from dismogas; until then, the prudent course is measured vigilance rather than alarm.
