The back-to-back incidents come as manufacturers face growing exposure from interconnected supply chains, third-party dependencies and increasingly connected operations.
Bajaj Auto has disclosed a ransomware attack affecting its systems and those of its wholly-owned subsidiary, Bajaj Auto Technology Ltd (BATL), days after Tata Electronics confirmed a cybersecurity incident involving its systems.
In a regulatory filing, Bajaj Auto said the ransomware attack occurred on June 23 at around 8:00 am IST.
The company said its technical teams, management and external cybersecurity experts responded immediately and initiated precautionary actions and response protocols to mitigate the impact of the incident.
According to the company, the measures undertaken have been successful based on the information available so far. The incident has also been reported to the Indian Computer Emergency Response Team (CERT-In).
Bajaj Auto did not disclose whether any customer or business data was compromised, whether manufacturing operations were affected, or whether a ransom demand had been received.
The company said its technical teams, management and cybersecurity experts continue to monitor the situation and implement protocols to contain the impact.
The disclosure comes shortly after Tata Electronics confirmed a cybersecurity incident after ransomware group World Leaks claimed to have accessed and published company data on the dark web.
According to Reuters, researchers who reviewed the alleged leaked data reported finding documents linked to Apple and Tesla, including engineering specifications, manufacturing documentation, quality standards and internal records. Reuters also reported that the leaked dataset allegedly exceeded 630 GB and contained over 200,000 files.
Tata Electronics said it activated response protocols after detecting the incident and maintained that manufacturing operations were not affected.
The incidents come as manufacturers continue to expand digital operations across production environments, supplier networks and business systems.
Supply-chain dependencies increase cyber risk
Manufacturing organisations rely on enterprise applications, cloud platforms, industrial systems, supplier portals and partner ecosystems to manage production, inventory, logistics and business operations.
As these environments become connected, disruptions can affect multiple systems, partners and business processes.
Manufacturers also manage large volumes of intellectual property, engineering designs, production specifications and supplier information, making them attractive targets for ransomware groups and cybercriminals.
The developments align with recent observations from CERT-In, which warned that interconnected enterprise environments, software supply chains and third-party dependencies are expanding cyber risk across organisations.
In its recent blueprint on defending against AI-assisted cyber exploitation, CERT-In said organisations should move towards continuous exposure management, rapid remediation, continuous monitoring and real-time validation of security controls.
The agency said vulnerabilities in a single component or dependency can potentially impact multiple organisations across interconnected digital environments.
CERT-In also warned that cyberattacks are becoming faster and automated, reducing the time available for organisations to identify and respond to threats.
The agency has called for stronger continuous monitoring, threat hunting, detection capabilities and faster remediation of critical vulnerabilities.
For manufacturers, this places greater emphasis on operational resilience alongside traditional cybersecurity controls.
Organisations are required to detect threats quickly, isolate affected systems and maintain business continuity while managing incidents.
The shift is also creating additional pressure on technology providers, service providers and channel partners responsible for securing enterprise infrastructure and managing security operations.
As manufacturers continue to modernise operations and expand digital supply chains, security strategies are increasingly moving beyond periodic assessments towards continuous monitoring, validation and resilience.
The recent incidents at Bajaj Auto and Tata Electronics show how cyber incidents are becoming a broader operational challenge for manufacturers managing connected production environments and complex supply-chain ecosystems.
