These attackers leverage search engine marketing (search engine optimisation) to make sure compromised websites internet hosting hyperlinks to malicious information are pushed as much as the primary web page of Google outcomes for generally requested questions. On this case, a person was taken to a compromised web site and downloaded a file containing a malicious JavaScript file. Whereas the JavaScript file was executed, there was little affect on the group because of SentinelOne correlating and associating the actions that adopted as malicious and autonomously stopping the assault.
And, with the assistance of AT&T, the shopper was capable of take additional remediation steps, allow further proactive prevention insurance policies, and ensure no different malicious domains have been noticed throughout the community.
