murni.co.id Listed by lockbit5 Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On April 26, 2026, the ransomware group lockbit5 listed murni.co.id on its leak site and stated that internal files had been taken from PT Murni Solusindo Nusantara. The number of individuals whose information may be involved is not known, and the company has not confirmed the scope or contents of any exfiltrated material. The incident is significant because the organisation provides ICT solutions and holds an ISO 9001:2015 certification, meaning it routinely handles technical and operational records that can contain customer or partner details.

Breaking down the breach

The only confirmed detail is the listing itself. Lockbit5 posted murni.co.id on its site and described the event as a ransomware attack in which internal files were removed. No figure for the volume of data, the number of records, or the timeline of the intrusion has been released. The organisation has not issued a public statement confirming or denying the claims.

The group behind it: lockbit5

Lockbit5 is the current iteration of the LockBit ransomware operation, a criminal group that has conducted numerous attacks since 2019. The group typically uses encryption to disrupt systems and then threatens to publish stolen files unless a ransom is paid. Its leak sites serve as a public catalogue of claimed victims. Any specific assertion about murni.co.id originates solely from the group’s listing and remains unverified by independent sources.

About murni.co.id

PT Murni Solusindo Nusantara operates as an ICT-based solution provider. Companies in this sector commonly supply hardware, software, networking services and managed infrastructure to other businesses and public-sector clients. The presence of an ISO 9001:2015 certification indicates documented processes for quality management, which often include handling of client configurations, project documentation and support records.

The information in question

The listing refers only to “internal files exfiltrated in ransomware attack.” No inventory of file types, no sample data and no confirmation of personal information have been made public. Organisations of this kind routinely store customer contact details, project specifications, network diagrams and administrative credentials; however, whether any of these categories were among the files taken has not been established.

Why it matters

Internal files from an ICT provider can include configuration data and access credentials that affect downstream clients. If such material circulates, it may increase the risk of further targeted intrusions against those clients. For individuals whose records appear in the material, the main exposure is the potential reuse of any email addresses or account details in subsequent phishing or credential-stuffing attempts. The organisation faces operational disruption and possible regulatory scrutiny once the full extent of the data is clarified.
