The National Cyber Security Centre (NCSC) has revealed that the unnamed team would have lost the cash had the club's bank not intervened.
The NCSC's Paul Chichester said: "The impact of cybercriminals cashing in on this industry is very real."
The organisation found that hackers were trying to compromise sporting organisations on a daily basis, often targeting business emails and using ransomware to shut down systems.
Chichester added: "Sport is a pillar of many of our lives and we're eagerly anticipating the return to full stadiums and a busy sporting calendar.
"I would urge sporting bodies to use this time to look at where they can improve their cybersecurity - doing so now will protect them and millions of fans from the consequences of cybercrime."
The hacking incident was one of several highlighted in a report as evidence that sport needs to improve its cybersecurity.
It also explained how a team in the Football League fell victim to hackers who cut off security systems, which blocked turnstiles and almost caused a fixture to be postponed.
In another incident, a member of staff at a racecourse lost £15,000 after trying to buy grounds-keeping equipment from a fake version of eBay.
Sir Hugh Robertson, chair of the British Olympic Association, described the report as a "crucial first step" in the fight against cybercrime.
He said: "This report is a crucial first step, helping sports organisations to better understand the threat and highlighting practical steps that organisations should take to improve cybersecurity practices."
