MADRID (AP) - The lawyer for an alleged Russian hacker said Friday that authorities in Moscow are fighting his extradition from Spain to the U.S., the third time in recent moves that Russia has moved to block U.S. prosecution of suspected cybercriminals.
Pyotr Levashov, a 37-year-old known as one of the world's most notorious spammers, was arrested earlier this year while vacationing with his family in Barcelona.
He is appearing Friday before Spain's National Court in Madrid to decide whether he should be judged in the U.S. on charges of fraud and unauthorized interception of electronic communications.
Levashov's lawyer, Margarita Repina, told The Associated Press that a Russian counter-extradition request was filed with Spanish authorities Thursday, hours before Friday's hearing.
The Russian Embassy in Madrid didn't immediately respond to requests for comment.
Authorities in the U.S. have linked Levashov, via his alias "Peter Severa," to a series of powerful botnets, or networks of hijacked computers capable of pumping out billions of spam emails.
The conflicting extradition request echoes the recent cases of Evgeny Nikulin, a Russian hacker accused by American authorities of penetrating professional networking site LinkedIn, and of Alexander Vinnik, who is wanted in the U.S. on charges of running a multi-billion dollar digital money laundering network.
Nikulin, who was arrested at a Prague restaurant in October, is the subject of a tug-of-war between the FBI, which wants him to face trial in the U.S. over hacks linked to several massive data breaches, and the Russians, who are seeking him on a far less serious charge.
On Tuesday, Vinnik's lawyer, Xanthippe Moyssidou, said the Russian, who was arrested in Greece in July over American allegations that he ran Bitcoin exchange BTC-e as a cash machine for cybercriminals, was also being sought by Moscow.
Vinnik is fighting extradition to the United States, but Moyssidou said her client was willing to return to Russia.
The arrests are part of a series of American-initiated operations over the past year to seize the alleged Russian cybercriminals outside their homeland, which has no extradition agreement with the U.S.
They also come as politicians in Washington are grappling with the allegation that Kremlin hackers intervened in the U.S. election to help President Donald Trump.
