Trend Micro warns for a backdoor that doesn’t write any files to the hard disk, which means it’s relatively hard to detect and analyse. For a while it was unknown how the malware was distributed. It was thought the malware was downloaded by the user or installed with other malware. But Trend Micro now discovered the distribution goes through USB sticks.
