Security firm Trend Micro also said it is conducting further research on the new trojan. 'We have asked our experts to conduct research on this new trojan source,' said Raimund Genes, chief technology engineer at Trend Micro Europe. Or to put it another way, Micro experts are trying to figure out what this new trojan can do.

Trend Micro named the new trojan 'emfsploit.a'. According to initial findings that the trojan contains malicious code that could ruin "explorer.exe" on some Windows systems that do not have patches installed.

At the same time, Trend Micro also gave updates to include the virus type in the dictionary defining its viruses. In particular, security firm defines emfsploit.a to be able to exploit security vulnerabilities in Windows and has the same expression as described in Microsoft's MS05-053 security patch for Enhanced Metafile.

'Our experts are currently working with Microsoft to find out if the TROJ_EMFSPLOIT.A trojan actually exploits the security vulnerability as outlined in MS05-053 or can only exploit one aspect. certain edges, 'Genes said.

Trend Micro discovered that this new trojan type could cripple some systems running Windows XP, but mostly Windows XP systems have not yet installed Service Pack 1. In contrast, Microsoft has said Service Pack 1 and 2 systems are affected by this error.

Thus, Trend Micro has officially confirmed the existence of this new type of trojan. But since it was discovered by security companies in Japan, there has been no new discovery about the existence of this new trojan.

Microsoft said the company is also working on a report on the new trojan, but the company also said that the ability to attack with this new trojan is not high.The company also recommends that users should quickly update the newly issued patches.
