Positiwise Infotech Pvt Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

On May 5, 2026, the ransomware group sinobi listed Positiwise Infotech Pvt on its leak site, stating that internal files had been exfiltrated during a ransomware attack. The number of individuals affected is not known, and no further details on the volume of data or the precise circumstances of the incident have been made public. This listing occurs amid a broader pattern of ransomware operations that combine encryption of systems with the threat of data release to pressure victims. Such incidents often leave organizations and their clients with limited immediate information about exposure.

Breaking down the breach

The available facts indicate that sinobi claims to have carried out a ransomware attack against Positiwise Infotech Pvt and to have removed internal files. The date the incident was first reported is May 5, 2026. No confirmed count of affected individuals, no description of the attack vector, and no timeline of when the intrusion began or how long data remained outside the organization’s control have been disclosed.

Who is sinobi?

Sinobi is a ransomware group that has appeared on leak sites in connection with multiple incidents. Groups of this type commonly deploy ransomware to disrupt operations and then publish samples of stolen data on dedicated sites when ransom demands are not met. Their listings function as public claims of responsibility rather than independently verified reports. Public records of the group’s activity show repeated use of data-exfiltration tactics alongside encryption.

Positiwise Infotech Pvt and its sector

Positiwise Infotech Pvt, also referenced as Positiwise Software Pvt Ltd, is a software development firm operating from bases in India and the United States. The company provides web development, e-commerce platforms, mobile applications, and custom software, serving clients across healthcare, retail, real estate, finance, and hospitality. Organizations in this sector routinely process business records, client specifications, and integration details that can include personally identifiable information belonging to end customers of those industries.

The information in question

The only data type explicitly named in connection with the listing is internal files exfiltrated during the ransomware attack. No inventory of specific file categories, no confirmation of personal data elements such as names, contact details, or financial records, and no statement on whether client databases were included have been released. The exact contents therefore remain unconfirmed beyond the general description of internal files.

Why it matters

Internal files held by a software development company can contain configuration details, project documentation, and communications that affect both the firm and its clients. When such material appears in ransomware claims, organizations in regulated sectors such as healthcare and finance face potential compliance questions and the need to assess downstream impact on their own customers. Individuals whose information may reside in those files have no immediate way to determine exposure because the scale of the incident is undisclosed.

What to do if you're exposed

Anyone concerned about possible involvement should monitor financial and email accounts for unusual activity and enable multi-factor authentication where available. Organizations that work with Positiwise Infotech Pvt may wish to review recent project files and access logs.
