Sinobi ransomware group targets Kan & Krishme

The threat actor known as sinobi has listed the Indian-based legal and intellectual property consultancy firm Kan & Krishme on its leak site. According to the announcement made on January 15, 2026, the group claims to have successfully carried out a cyberattack against the organization. This incident follows a claimed attack date of January 11, 2026.

In typical double extortion ransomware schemes, threat actors not only encrypt an organization's internal systems to disrupt operations but also exfiltrate sensitive data to use as leverage. By threatening to release this stolen information on a public leak site, attackers aim to pressure the victim into paying a ransom to prevent the exposure of confidential files. This tactic increases the pressure on organizations, as the threat of a data leak can lead to significant regulatory, legal, and reputational consequences.

Claims of encryption and ransom demand

The sinobi ransomware group has issued a specific ransom demand in relation to this incident. The group is demanding a payment of 5,000,000 USD in exchange for the release of the data they claim to have stolen. The announcement explicitly states that the organization's data has been both encrypted and exfiltrated by the attackers.

While the threat actor has provided visual evidence in the form of screenshots showing various file directories, there is no detailed breakdown provided regarding the specific types of data involved in the breach. The listing does not provide information regarding the total size of the data stolen or the specific file count. Consequently, the exact scope of the exfiltrated information remains unconfirmed beyond the visual directory structures shown by the group.

Organization profile

Kan & Krishme is a law firm based in India that specializes in several areas of law, including patents, trademarks, design, and advertising law. Operating under the regulations of the Bar Council of India, the firm provides legal information and resources to its clients. Given its specialization, the firm handles sensitive intellectual property and legal matters.

Potential impact and industry implications

This incident may pose a significant risk to client confidentiality and the intellectual property rights managed by the law firm. If sensitive patent and trademark information is included in the leaked data, the commercial interests of third parties could be compromised. Such an outcome highlights the high stakes involved when professional service firms specializing in intellectual property are targeted by cybercriminals.

Furthermore, the organization's legal obligations under Indian data protection regulations may be triggered by this event. Beyond legal compliance, such a leak could lead to a loss of client trust and long-term reputational damage for the firm. Information regarding the sinobi group remains limited, making it difficult to attribute the attack or understand their specific tactics, techniques, and procedures.

For organizations operating within the professional services and legal sectors, such incidents underscore the importance of robust cybersecurity frameworks. Common defensive steps for organizations facing these threats include maintaining offline, immutable backups to mitigate the impact of encryption, implementing strict access controls to protect sensitive client files, and conducting regular security awareness training for staff. Additionally, monitoring for unauthorized data exfiltration and maintaining a comprehensive incident response plan are critical components of a modern defense strategy against ransomware groups.
