Once again, Flipkart-owned online travel aggregator Cleartrip has been the victim of a data breach. However, this time is unlike the hack in 2017, when the hacker group Turtle Squad hacked and defaced its website for a few minutes.

For its part, the online travel aggregator’s information security team has joined forces with an external forensics partner in order to tackle the issue. It has also reached out to the proper authorities and will be taking further legal action against the hackers.
Cleartrip has also informed CERT-In (the Indian Computer Emergency Response Team) about the breach within six hours, in…
