CEO Kris Marszalek told the media that nearly 400 customer accounts had been compromised.
During the hack, Crypto.com paused its users' ability to withdraw funds.
"We have a small number of users reporting suspicious activity on their accounts. We will be pausing withdrawals shortly, as our team is investigating. All funds are safe," the company said in a tweet.
Marszalek also reiterated in a tweet that "no customer funds were lost."
Blockchain security and analytics company Peckshield, however, tweeted that Crypto.com lost about $15 million (around 4,600 ethereum).
"The @cryptocom loss is about $15M with at least 4.6K ETHs and half of them are currently being washed via @TornadoCash," Peckshield tweeted.
Tornado Cash is a platform that obscures cryptocurrency transactions so that these are harder to be tracked.
Marszalek claimed that Crypto.com's 200 security professionals had created a "very robust" infrastructure and stated it had defence-in-depth.

According to reports, BitMart had promised a full reimbursement to the victims of the platform-wide $200 million hack.
Hackers stole various crypto tokens on December 4, after using a stolen privacy key to gain access to one of BitMart's hot wallets.
