"The tool is very similar to Hispasec's legitimate 'Virus Total' tool. In fact, the increasing interest in these new tools coincides with the removal of the 'do not distribute the sample' option in 'Virus Total' which allowed files to be scanned without sending the sample to security companies," explains Luis Corrons, Technical Director of PandaLabs.
These tools represent another piece of the new malware dynamic, in which cyber-crooks no longer seek to cause widespread alerts and make the headlines, but to go unnoticed. They therefore want to check their creations are undetected by companies before launching them.
"Even if their creations were detected by one or two companies, they could still launch them, as they would affect all users with different security technologies," says Luis Corrons.
