Summary

First observed on July 2019, Bolik is an advanced polymorphic banking trojan currently targeting English-speaking countries.

Affected platforms

The following platforms are known to be affected:

Microsoft Windows

Microsoft Windows - All versions

Threat details

Bolik is typically delivered packaged within legitimate applications hosted on third-party sites, or via disguised download links on compromised legitimate sites. However, newer campaigns will use full copies of legitimate sites in an attempt to trick users into downloading the malware directly. Bolik's operator will take great care in producing these spoof sites, including using search engine optimisation and valid SSL certificates, in order to increase the likelihood of users visiting the sites.

Once installed, Bolik will attempt to extract user credentials from a number of applications, as well as attempting to phish sensitive information when users visit specific sites. Certain Bolik campaigns will also deliver the AZORult and Predator trojans.

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, anti-virus and other security products are kept up-to-date. Regular anti-virus and security scans are performed on your organisation’s estate. All day-to-day computer activities such as email and internet are performed using non-administrative accounts. Strong password policies are in place. Network, proxy and firewall logs should be monitored for suspicious activity. User accounts accessed from affected devices should be reset on a clean computer. Your organisation adopts a holistic all-round approach to Cyber Security as advocated by the 10 Steps to Cyber Security.
