Scranos spreads under the guise of cracked or free software signed by a stolen digital certificate, which is still valid, and attacks Windows and Android systems. Most of the infected machines are running Windows 10. Downloadable modules are small, and after completing the task, the malware deletes them making it harder for researchers to analyze the threat and evading anti-virus solutions’ attention. At the moment, Scranos modules steal a victim’s payment accounts from Facebook, Amazon and Airbnb webpages, as well as Steam accounts, send malicious files with phishing messages to victim’s friends on Facebook, Install malicious browser extensions and steal browsing history. Most of the experts were surprised by the module that screws subscribers and the views on Youtube channels using the Chrome browser, as in China where the malware is most widespread access to Youtube is restricted.
