In this market, it's possible to access 10,000 bots - infected computers connected to the internet - for about $15; stolen bank account details vary from $1 to $1,500 depending on the level of detail and account balance (bulk buying earns discounts, too). Many pioneering cyber criminals now sell their software, rather than repeat the crime themselves; it's possible to buy a copy of Zeus, a Trojan horse virus that steals banking details by logging the unknowing victim's keystrokes, for as little as $700. Up-to- date versions, with new features that help the hacker avoid law enforcement detection, can cost $15,000. And even if police can track down the criminals, pursuit isn't easy. Certain countries, such as Russia and lately Brazil, which have traditionally suffered from organised crime, have emerged as bases for cyber gangs, too, but cyber criminals aren't confined by geography and operate across borders. 'It's difficult for authorities to move across jurisdictions as easily as for traditional crime,' says Clemente.
But the net may be tightening. Based in Vauxhall, the Police Central e-Crime Unit of the Met has gone from 20 to 104 staff since it was set up in 2008. It's been busy, too: 'The PCeU has experience of investigating direct cyber attacks such as DDos, phishing, hacktivism, botnets, exploiting social networks, malware enabled fraud and extortion,' says Det Chief Inspector Terry Wilson. In September, the unit raided a house in Chingford, Essex, and arrested 19 people, following a tip-off from the FBI and subsequent investigation in concert with UK banks. The Eastern European gang had used a version of Zeus to steal £3 million from bank accounts belonging to members of the public. In November, the ringleaders were jailed for four years. The success of other such operations saved the UK more than £140 million from March to October alone, according to the Met. And it says that four new investigations will soon result in prosecutions - operations Westphalian, Yukon, Crossbill and Loyosa.
Despite these successes, Belial is sceptical about the Met's capabilities. 'The e-crime units are under-resourced and have no capability to come close to dealing with this subject matter,' he says. Wilson admits his unit faces a tough task: 'Cyber crime is constantly evolving and becoming more mainstream. More of the criminal fraternity will be drawn to the low-risk, high-yield benefits.'
