438 Bitcoins Worth Nearly $3.5 Million Stolen From Exchange In India, CSO Accused (indiatimes.com)

William Robinson shares a report from The Economic Times: Nearly 438 bitcoins, worth nearly $3.5 million, were stolen from a top exchange firm in India in what is being billed as the biggest cryptocurrency theft in the country so far. The exchange, which has over two hundred thousand users across the country, found that all the bitcoins that were stored offline had vanished. It was later found that the private keys -- the password that is kept by the company and is stored offline -- were leaked online, leading to the hack. The company tried to trace the hackers, but found that all the data logs of the affected wallets had been erased, leaving no trails about where the bitcoins were transferred. Coinsecure, a Delhi-based cryptocurrency exchange, is accusing its CSO, Amitabh Saxena, of siphoning off the money from the firm's wallet. The exchange is urging the government to seize Saxena's passport, fearing that he may leave the country.

You need to read more carefully...from the article: "The company tried to trace the hackers, but found that all the data logs of the affected wallets had been erased, leaving no trails about where the bitcoins were transferred."

It's not the blockchain record that was erased.

It's also important to understand that an exchange often has transactions on a data base & only once bitcoin is withdrawn does it register on the blockchain because all the trading happens off-chain.

As an exchange sends bitcoin to many addresses constantly it will take a great deal of time to trace it and by then the thief may have cashed out.

Of course if they managed to find the Mt. Gox hacker after so many years because it was all traced on the blockchain then stealing bitcoin and keeping it on-chain is not a very smart idea...

In summary, as far as we know; bitcoin is the only tried & tested decentralized public financial blockchain that is a currency agnostic settlement layer application and it is secure.

(Literally any other chain is so far deemed less secure, untested, private, not decentralized etc etc.)
