- Tactics: The group employs unethical extortion practices, targeting sensitive sectors and even individuals, such as cancer patients at Fred Hutch.
Implications
This attack underscores the growing threat of ransomware campaigns targeting critical industries like manufacturing and engineering. The potential exposure of intellectual property and client data could have severe consequences for Tata Technologies’ reputation and its clients’ operations.
