Warrant issued for alleged mastermind of online attacks In what appears to be an unprecedented move, the mainland has issued an arrest warrant for a Taiwanese secret agent accused of hacking into hundreds of sensitive government websites. Mainland security agencies identified Lee Fang-jung, in his late 20s, as the mastermind of recent online attacks on websites of several hundred government units. Through the Global Times, an affiliate of the mainland's People's Daily, a mainland public security department said the targets of the massive internet attack included networks operated by the government, the People's Liberation Army, defence technology institutions and defence industry organisations across the mainland and its autonomous regions. They also included dozens of the mainland's diplomatic posts abroad. The hackers gained access to information related to political, military, diplomatic, economic, medical and health affairs, the Global Times said. The security department added that it had already discovered overseas agents spying on tens of thousands of major computer systems using Trojan horse programmes, with 42 per cent of attacks coming from Taiwan and 25 per cent from the US. Taiwanese media identified Mr Lee as a spy formerly stationed in Moscow for Taiwan's Military Intelligence Bureau. Through his computer expertise, Mr Lee, who had returned to Taiwan, placed a number of Trojan horse programmes in mainland servers. The reports said this allowed him remote access to the contents of the computer systems he was interested in. Yang Yi , spokesman of the Taiwan Affairs Office under the State Council, indirectly confirmed the report yesterday in Beijing. 'We have taken note of the related reports,' he said. 'For years, Taiwanese intelligence agencies have stolen secret network information on a massive scale, which has caused vile consequences.' He said that anyone engaging in sabotage on the mainland would be punished. Taiwan's Defence Ministry declined to comment. 'We are not aware of such a matter,' Vice-Minister Lin Chen-yi said in a legislative session. Asked by lawmakers how the defence ministry would protect Taiwanese agents wanted by the mainland, he said the Military Intelligence Bureau had a full protection programme for all of its workers. Chuang Ho-tzu, a legislator from the ruling Democratic Progressive Party, lashed out at the mainland for accusing the island of hacking. 'Only a thief would accuse others of being thieves,' she said, claiming that hundreds of thousands of mainland hackers had for years launched attacks on the island's sensitive government and military websites. She said mainland Trojan horses accounted for about one-third of such backdoor viruses in the world and called on the government to condemn the mainland's hacking. Mr Yang also declined to comment on a Taiwanese request that the mainland return the wife of a fugitive hiding in Shanghai. Taipei's Straits Exchange Foundation has asked Beijing to return Wang Chin Shih-ying. The woman and her husband, Rebar Group founder Wang You-theng, are wanted by Taiwanese authorities for allegedly embezzling more than NT$600 billion (HK$143.48 billion) from the group before fleeing. Wang You-theng is believed to be in the US. Mr Yang said he had no information that the woman was in Shanghai.
