Infected Hosts

Description

This widget shows the number of hosts in the network infected with malware over the selected report period.

Note - Select the report period in the top left corner of this view. For example, Last 7 Days, This Month, and so on.

The Security Gateway Dedicated Check Point server that runs Check Point software to inspect traffic and enforce Security Policies for connected network resources. treats a host as infected when it detects an outbound malicious communication or propagation event (lateral movement) from that host.

Anti-Bot and IPS events show this malware communication. The events shown have a Severity and Confidence Level of Medium and above.

To open the next drill-down level, double-click a headline or matching icon.

The drill-down view shows summarized data about infected hosts on your internal network.

Available Widgets

Widgets available in the drill-down view:

Widget	Type	Description
Infected Hosts	Infographic	Shows the number of hosts on the network infected with malware.
Top 20 Infected Hosts	Chart	Shows top hosts (based on the logs count) that connected to Command and Control (C&C) servers. Shows: The source IP addresses of the top 20 infected hosts The number of detected malicious connections Different colors show different infected hosts.
Top Malicious Command And Control Connections	Table	Shows top hosts (based on the connection rates) that connected to Command and Control (C&C) servers. Shows: Hostnames of the infected hosts Source IP addresses of the infected hosts Source usernames C&C server IP addresses Number of malicious C&C connections
List of Infected Hosts	Table	Shows the list of infected hosts. Shows: Hostnames of the infected hosts Source IP addresses of the infected hosts Source usernames Signature names of the detected malware (based on Check Point ThreatWiki and Check Point Research) Malware action Number of logs
Timeline of Infections (Top 20)	Timeline	Shows the timeline of malicious connections to Command and Control (C&C) servers across all infected hosts. Shows: Source IP addresses of the top 20 infected hosts Number of logs for the top 20 infected hosts Dates and times Different colors show different infected hosts.

Widget Query

In addition to the Default Query, the widget runs this query:

(blade:Anti-Bot AND severity:(Medium OR High OR Critical) AND confidence_level:(Medium OR Medium-High OR High) NOT "Mail analysis") OR (blade:IPS AND "Malware Traffic")

Best Practices

1. To see which internal hosts initiate the most malicious connections with Command and Control (C&C) servers:

   • Examine the Top Malicious Command And Control Connections.

   • Examine the Threat Prevention logs from the Security Gateway about the internal hosts that initiate the most malicious connections with C&C servers. To do so, double-click the host entry. In the Threat Prevention logs, examine the Suppressed Logs column (see Log Fields).

2. For every infected host, query for its IP address to see all threat events related to that host.

   This lets you better understand the malicious behavior of the infected host.

   To query an IP address for all related threat events:

   1. Right-click an IP address.

   2. In the context menu, click Filter: "<IP Address>"

   3. At the top, click Cyber Attack View - Gateway.

3. If you configured the Anti-Bot Check Point Software Blade on a Security Gateway that blocks botnet behavior and communication to Command and Control (C&C) centers. Acronyms: AB, ABOT. Software Blade Specific security solution (module): (1) On a Security Gateway, each Software Blade inspects specific characteristics of the traffic (2) On a Management Server, each Software Blade enables different management capabilities. based on Check Point recommendations, the Security Gateway generates both Detect and Prevent logs.

   The Anti-Bot Malicious software that neutralizes Anti-Virus defenses, connects to a Command and Control center for instructions from cyber criminals, and carries out the instructions. Detect logs do not mean that the Security Gateway allowed malicious connections.

   The Anti-Bot can generate the Detect logs, if you enabled the DNS trap feature.
