For the third quarter this year, about 43 percent of all fraudulent clicks came from computers within botnets. The figure is the highest in four years, when Click Forensics began producing reports. For the same quarter a year ago, botnets accounted for 27.5% of bad clicks. Researchers have spotted notable code overlap between the Sunburst backdoor and a known Turla weapon.
