M-POWER Information, Taiwan Listed by nightspire Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On April 18, 2025, the ransomware group nightspire listed M-POWER Information, Taiwan, on its leak site, claiming the company had been hit by a ransomware attack in which internal files were exfiltrated. The number of people affected remains unknown, and public detail beyond the listing itself is limited.

This report matters because the claim involves a Taiwanese information-services organisation whose internal files could contain operational or client-related material. Until more is confirmed, the listing stands as an unverified assertion by the group rather than an independently verified breach disclosure.

Inside the incident

Public reporting on the incident is sparse. The sole concrete detail available is that nightspire listed M-POWER Information, Taiwan, on April 18, 2025, and stated that internal files had been exfiltrated during a ransomware attack. No timeline of the intrusion, no confirmation of encryption or ransom demand, no volume of data taken, and no independent verification of the claim have been released. The number of people potentially affected is listed as unknown. Method of initial access, duration of presence inside the network, and any subsequent recovery steps by the organisation remain undisclosed.

In short, the known facts consist of a single leak-site entry and the assertion of internal-file exfiltration. Everything else about how the incident unfolded is unconfirmed.

The group behind it: nightspire

Nightspire is a ransomware operation that follows the now-common double-extortion model: encrypting systems while also stealing data and threatening to publish it if payment is not made. The group maintains a public leak site where it posts victim names, sometimes accompanied by sample files or countdown timers. Like other ransomware crews active in recent years, nightspire typically targets mid-sized organisations across multiple sectors and geographies, using the threat of data exposure to increase pressure.

In this case the group claims M-POWER Information, Taiwan, as a victim and asserts that internal files were taken. No further statements, screenshots, or data samples specific to this listing have been described in the available record. The listing itself should therefore be treated as a claim by the threat actor, not as confirmed fact.

About M-POWER Information, Taiwan

M-POWER Information is a Taiwanese organisation operating in the information-technology and services sector. Companies of this type typically provide IT consulting, systems integration, software support, or related digital services to business clients. As such they routinely hold internal operational documents, employee records, client contracts, project files, and technical configurations.

A breach at an information-services firm is consequential because the data it holds often includes material belonging not only to the company itself but also to its customers. Even when the precise contents remain unconfirmed, the potential reach of any exposure extends beyond the organisation’s own staff to the businesses and individuals who rely on its services.

What was likely exposed

The only data type named in the available facts is “internal files exfiltrated in ransomware attack.” No further breakdown—such as employee personal data, client lists, financial records, or source code—has been disclosed. Exact contents are therefore unconfirmed.

Organisations of this kind typically hold material that can include:

• Internal administrative and operational documents
• Employee contact and HR-related records
• Client contracts, project files, and correspondence
• System configurations and technical documentation

Whether any of these categories were among the files claimed by nightspire cannot be verified from public information. Readers should treat all specifics beyond the phrase “internal files” as unconfirmed.

What's at stake

For individuals whose information may have been present in the exfiltrated files, the practical risks include unwanted contact, phishing attempts that reference genuine internal details, and possible identity-related misuse if personal data was included. Because the volume and exact nature of the data remain unknown, the scale of these risks cannot yet be quantified.

For the organisation itself, the stakes involve potential disruption of operations, loss of client confidence, regulatory scrutiny under Taiwanese data-protection rules, and the cost of investigation and remediation. Even an unverified listing can generate reputational pressure and force the company to divert resources to incident response. Until independent confirmation or further disclosure occurs, both the human and organisational consequences stay provisional.

If your data was in this claimed breach

If you have a past or present relationship with M-POWER Information—whether as an employee, contractor, or client—consider the following practical steps. Change passwords on any accounts that may have been linked to the company, enable multi-factor authentication where available, and monitor financial and email accounts for unusual activity. Be cautious of unsolicited messages that appear to reference internal company matters; such messages could be phishing attempts built on stolen data.

You can also run a free exposure scan of your email address to check whether your information has already surfaced in known breach data sets. Remain alert to further official statements from the organisation or from Taiwanese authorities, as additional Reported Details may emerge over time.
