Threat details

SkyGoFree is delivered through fake mobile carrier websites, where it is disguised as a system update. When launched by the user it removes its own icon, to appear as though the update has finished, but it continues running in the background. It then attempts to gain root access to the infected device and has the capability to open a backdoor for full remote control. SkyGoFree can also record audio, connect to hostile WiFi networks, steal WhatsApp messages and install additional malware.

Remediation steps

Type	Step

To prevent and detect a trojan infection, ensure that: A robust program of education and awareness training is delivered to users to ensure they don’t open attachments or follow links within unsolicited emails. All operating systems, antivirus and other security products are kept up to date. All day to day computer activities such as email and internet are performed using non-administrative accounts. Strong password policies are in place and password reuse is discouraged. Network, proxy and firewall logs should be monitored for suspicious activity. User accounts accessed from infected machines should be reset on a clean computer.
