Trend Micro researcher Karla Agregado recently uncovered malware in rogue versions of the Opera Mini mobile phone browser.

"Agregado says that his research team recently encountered a website that seems to have been designed to be viewed on a mobile device," Infosecurity reports. "The site -- which is in Russian -- appears to look like the Opera site and informs visitors that they need to upgrade their version of Opera Mini."

"'All of the links in [the] website lead to the download of the malicious file OperaMini.jar, which is detected as J2ME_FAKEBROWS.A,' he says in his latest security posting," the article states. "When executed into the device, the code checks if the mobile phone uses certain service centers and then proceeds to sending text messages to premium numbers."
