In May, Dr.Web’s statistics registered a 1.49% increase in the number of unique threats compared to April; while the number of all detected threats increased by 14.51%. Malware and unwanted programs statistics show the prevalence of adware and installers. E-mail traffic is still dominated by malware that uses the vulnerabilities of Microsoft Office programs, but in May we also registered an increase in the spread of the dangerous trojan, Trojan.Fbng.8 (FormBook).
In May, Doctor Web’s researchers warned about unique malware for the macOS operating system–Mac.BackDoor.Siggen.20. It allows attackers to download and execute malicious python code on the victim’s device. Additionally, websites that spread the malware also infect their visitors with a Windows spyware trojan, BackDoor.Wirenet.517 (NetWire). The latter is a well-known RAT trojan used by hackers for controlling a victim’s PC remotely. It has several malicious functions, including using the camera and microphone on the victim’s device. The RAT trojan also has a valid digital signature.
