Threat Risk: Low
Victim: Tata Consultancy Services (TCS)
Incident: Alleged leak and sale of 800,000 employee records on the darknet.
Impact: Potential exposure of employee PII, though the company claims no operational or customer system impact.
Attacker: TheHatman
Analysis: Threat actor ‘TheHatman’ claims to have acquired a massive Azure dump of TCS employee data via password spraying and MFA fatigue. While TCS denies a current system breach, the alleged leak of 800,000 records highlights the persistent risk of credential-based attacks. The company maintains that the leaked information is legacy data over four years old.
Recommendations: Implement phishing-resistant MFA to mitigate MFA fatigue attacks; Enforce strong password policies and monitor for password spraying attempts; Regularly audit and rotate legacy credentials to reduce the impact of old data leaks
