14 DAY TRIAL // Not long ago, McAfee released its threats report for the first quarter of 2013. According to the report, the Koobface worm, which spreads on social networks, has been on the rise.
However, it turns out that it isn’t quite so. In a blog post published on Friday, the company admitted that it made a mistake regarding the Koobface count.
The Koobface malware has actually continued its decline, which started a year and a half ago when Facebook intervened.
“Besides the number of changes made to a malware’s code base, sample counts can also be influenced by repacking of the same underlying code (a common evasion tactic used by malware distributors), garbage data or junk instructions added to binaries, and other forms of server or client polymorphisms,” said McAfee’s Craig Schmugar.
“Another complication arises from what is often called a cocktail, in which a parasitic virus inhabits a host file that is itself another piece of malware.”
