Hackers Claim to Have Breached Gamdom’s Entire Player Database and Demand a Ransom

Hackers have claimed to have breached the entire player database of crypto casino Gamdom, allegedly gaining access to information linked to 15.4 million accounts. The group, known as WhiteArmor, is demanding $15 million in Bitcoin to prevent the data from being disclosed. To support its claims, the attackers have published records belonging to 100 users, although their authenticity has not yet been verified. Gamdom founder Felix Roemer has since disputed the alleged scale of the breach.

WhiteArmor Claims Access to 15.4 Million Accounts

WhiteArmor, a hacking group reportedly emerging in autumn 2026, claims to have obtained a database containing information on 15.4 million Gamdom accounts. According to the group, the database includes 146 fields of information, while the combined profits associated with the accounts allegedly exceed $1 billion.

The hackers have published data from 100 accounts as evidence of their alleged access. However, the records have not been independently verified, so it remains unclear whether they are genuine and whether they came from Gamdom's systems.

The group is demanding $15 million in Bitcoin in exchange for keeping the allegedly stolen information private. This puts the crypto casino under pressure to respond to claims that could affect a large number of its players.

Hackers Describe How They Allegedly Accessed Gamdom

According to WhiteArmor, the alleged breach was made possible by an old internal account with administrative privileges. The group claims that Gamdom had left the account active for years without disabling it.

The attackers say they used this access to enter the casino's management panel and reach internal data. If accurate, the account could have provided a way into systems containing sensitive information.

WhiteArmor has not provided independently verified evidence establishing the full extent of its alleged access. Its claims about the number of affected accounts and the contents of the database therefore remain unconfirmed.

The ransom demand comes after Gamdom suffered a separate cyberattack on October 13. During that incident, hackers stole more than $3 million from the casino's hot wallets, according to earlier reports. The latest claims have raised further questions about the security of the operator's systems and whether the attackers behind the incidents are connected.

Gamdom Founder Denies Claims of a Mass Data Breach

Gamdom founder Felix Roemer has rejected WhiteArmor's assertion that the group accessed a database containing 15.4 million accounts. According to Roemer, the casino does not have that many accounts.

He acknowledged that the attackers might have obtained information from several hundred accounts, but said the company was still checking whether the records published by WhiteArmor were authentic. Roemer added that Gamdom's investigation following the October 13 attack had found no evidence of a mass download of its user database.

The founder suspects that the people behind the extortion attempt could be the same individuals responsible for the earlier attack. He suggested that they might be using a limited sample of account information to make the alleged breach appear much larger and pressure the casino into paying the $15 million ransom.

Roemer also disclosed that the financial damage from the October attack was greater than initially reported. In addition to more than $3 million stolen from hot wallets, the attackers allegedly took around $1 million through the system involving private keys. The total losses amounted to approximately $4.2 million.

For now, Gamdom disputes WhiteArmor's claim that its entire player database was compromised. The casino is investigating the published records, while the hackers' allegations about 15.4 million accounts remain unverified.
