Belgium's national table tennis federation and its French-speaking branch are investigating a cyberattack after a hacker claimed to have stolen data on tens of thousands of members and users. Jean-Michel Mureau, president of the AFTT, confirmed that "there was indeed an attack" and said the Royal Belgian Table Tennis Federation was also affected, with the federation alerted on Thursday and its IT provider asked to establish what data was compromised. A statement issued on Monday said the AFTT was treating the matter seriously and had checked its own systems and those of the service provider responsible for its website, finding at that stage no evidence that its infrastructure had been compromised, and no evidence that members' phone numbers or email addresses had been taken. The attacker, using the handle Venus1337, claims to have obtained nearly 1.7 GB of data covering more than 66,800 members and 17,400 users plus club administrative accounts, and samples reportedly posted online include names, membership numbers, member and user information and records of sporting sanctions. The incident was first publicised by FrenchBreaches, a leak-tracking site. The gap between the claim and the federation's findings is the story: for a membership body, the sensitive element is not the contact list but sanction records attached to named individuals.
