Cyber Secure Institute claims that based on their previous studies into the average cost of suck malware attacks, the economic loss due to the Conficker worm could be as high as $9.1 billion. Despite that their analysis also considered a much limited infection rate (200,000 infected hosts), they claim that the cost of the virus in this case is still around $200 million. The worm returned in recent attacks against web applications, IP cameras and routers. The relentless rise in COVID-19 cases is battering already frayed healthcare systems.
