The boss of a Russian online payments processor has been arrested over claims he ordered a cyber-attack on a rival firm.
ChronoPay co-founder and CEO Pavel Vrublevsky was picked up by authorities at a Moscow airport last week following an investigation into a distributed denial of service (DDoS) attack on Assist.ru in 2010.
At the time of the attack, the two companies were battling it out for a plum contract with government-owned airline Aeroflot for online ticket selling.
ChronoPay attorney Dave Schlendorf told the Financial Times that Vrublevsky was arrested after he was implicated in the scam by another man, Igor Artimovich, suspected of carrying out the attack.
Vrublevksy, who denies the charges, is being held without bail ahead of a hearing set for a month's time, says the FT.
According to security blogger Brian Krebs - who has covered the story extensively - ChronoPay has also been heavily linked with scareware scams while Vrublevksy's other business is a "rogue" online pharmacy called Rx-Promotion.
