Researchers have released a report on the threat of Tinba, malware using website-injection tactics to steal login information from a variety of websites, including those of financial institutions.The threat was named Tinba, or Tinybanker, because of its small size among banking malware, approximately 20 kilobytes, according to researchers at Trend Micro and CSIS Security Group, who wrote the report. Tinba has affected more than 60,000 users in Turkey, primarily stealing login details from sites like Facebook, free German webmail service GMX, Google and Microsoft. The malware has also targeted government portals and Turkish banks to steal login information. Its infrastructure is believed to be located in Russia and Lithuania.
