U.K.-based cryptocurrency exchange Cashaa reported that hackers stole more than 336 Bitcoin (BTC). The company has ceased all the crypto-related transactions, however, users were reportedly not affected by this hack.

The company suspects that the hackers are based in east Delhi, India. The company claims it has filed a cybercrime incident report to the Delhi crime bureau with acknowledgment number 20807200031555 under the cryptocurrency crime category.

Cashaa suspects a piece of malware was installed onto the system that facilitated exchange transfers, such as user withdrawals. The malware notified the hacker when an employee logged into the account on July 10 and made two transfers from the wallet. Cashaa was using a Blockchain.com wallet to store and send BTC. Exchange CEO Kumar Gaurav said to Cointelegraph:

“We are still investigating the damage caused by the incident and suspend all the withdrawals for 24 hours. We have called the board meeting to decide whether the company will bear all the losses.”

Cashaa says it’s trying not to allow hackers to sell the Bitcoin on exchanges. In a tweet, the company also provided the Bitcoin address of the hackers.

Indian exchanges extend a hand

Some crypto exchanges have said that they will extend support to Cashaa in monitoring the addresses and report any suspicious transactions. FOr example, Nischal Shetty, founder and CEO of WazirX cryptocurrency exchange, told Cointelegraph that “we will help Cashaa in all the manner and also working on setting up certain security standards for exchanges,” adding: “WazirX will ensure that we lock any funds that reach us from the hacked wallet. We have informed the Binance team as well.”
