An investigation is underway as the ICC, which is not commenting on the matter, reported the incident to law enforcement agency in the US. The ICC has allegedly lost close to USD 2.5 million after becoming a victim of cyber crime, according to a report.

"The route used by fraudsters to commit the financial scam was Business E-mail Compromise (BEC), also known as e-mail account compromise, which the Federal Bureau of Investigation (FBI) describes as 'one of the most financially damaging online crimes'," the report stated.

How the scam took place is not yet known.
