Setting the scene

Example: File infections detected

LogPoint SIEM use cases: File infections detected

Query

label=Detect label=File label=Infection | chart count() by sender,sender_domain,hash, receiver

Drill down on the first row and identify the checksum.

LogPoint SIEM use cases: Identifying Checksum

Use the checksum to drill back to Virus Total.

Conclusion

Raise the flag and further investigation required to investigate the impacts of the infection.

Raise flag

Create an incident for follow up.

LogPoint SIEM use cases: Entities observed in list of threat indicators

Investigation

Apply the identified hash as the filter.

LogPoint SIEM use cases: Identified Hash as Filter

Pick each user associated with the recipient emails.

User Rita shows failed login attempts to various servers.

LogPoint SIEM use cases: User Multiple Failed Logins

Go to the search page to see the details.

Example: Failed login attempt for specific user

LogPoint SIEM use cases: Failed login attempt for specific user

Query

label=Login label=Fail user="rita.mm" | chart count() by source_address,workstation,user,host order by count() desc

Pick one the source IPs used by user Rita to check if there are other failed attempts or not.

We observe that with source 192.168.2.101 there are 4 failed attempts from the same source.

Example: Failed login attempt for specific source

LogPoint SIEM use cases: Failed login attempt for specific source

Drill down on this event.

We observe that a disabled account is trying to login to the Domain Controller, the substatus code 0xC0000072 actually relates to login failed on disabled account.

LogPoint SIEM Threat Hunting use cases Failed login attempt on multiple filters by failure sub status

Now we go back to the search template to check for IOCs associated with source 192.168.2.101.

LogPoint SIEM use cases: IOCs associated with source

We drill down on category “Malware Command And Control” to check other source addresses associated with it.

Example: Threat indicators for malware command and control

LogPoint SIEM use cases: Threat indicators for malware command and control

Query

category="Malware Command And Control" | chart count() by source_address

Remediation/Reporting

During the process of threat investigation, we identify that user Rita is compromised and should be disabled. While user Rob should be deleted if not to be enabled in the future.

Carry further investigations on the incident to validate if there were any activities of the identified threat indicators in the past.

Threat indicators for malware command and control appended to list

Query

category="Malware Command And Control" | chart count() by destination_address | process toList(ACTIVE_IOCS,destination_address)

Search historical events for any activities associated with the IPs in the ACTIVE_IOCS list.

The infected systems should be cleaned and the firewall rule should be updated to block the connections to the “Command And Control Servers”.

Example: Entities observed in list of threat indicators

Query

source_address IN ACTIVE_IOCS OR destination_address IN ACTIVE_IOCS
