Traps Agent 6.1.5 Addressed Issues
Fixed an issue where the content update failed on the endpoint due to network issues, and the agent policy was being updated even though the content update did not contain policy updates.
Fixed an issue where the Ransomware Protection module accessed certain file objects from invalid execution contexts, causing processes running on the endpoint to halt or consume high CPU.
Fixed a race condition between the Cortex XDR agent injector and certain Syslog and DL processes running on the endpoint which could cause the processes to hang during startup.
Extended the Cytool log collect timeout from two minutes to ten minutes to support the collection of large log files.
To prevent license leakage, now Cortex XDR will prevent the re-registration of a Golden image instance until a user logs on.
Addressed security issues.
Fixed an issue where the security module was set to notify, however
security_events.dbreported the process as failed to terminate (
Target process termination: Yes (Failed)).
Now when the agent settings profile on the endpoint is set to hide the Cortex XDR agent tray icon on the endpoint, the icon will be hidden already when the user logs on or reboots the machine, and not only after the first agent heartbeat.
Fixed an issue where the VDI instance created from a Golden image that included proxy configuration did not receive the proxy configuration.
Fixed an issue where you could not restore a quarantined file to a custom location using Cytool on a Mac endpoint running macOS10.15.
Traps Agent 6.1.4-h1 Addressed Issues
Windows 10 only)
For all Windows 10 endpoints Palo Alto Networks strongly recommends that you upgrade to the latest Windows Update that has a fix for vulnerability CVE-2020-0601.
For Traps agents running on unpatched Windows 10 endpoints, this version includes a hotfix to address vulnerability CVE-2020-0601. When there is an attempt to exploit CVE-2020-0601 on an unpatched Windows 10 endpoint, the Behavioral Threat Protection (BTP) module will detect and terminate the malicious executable.
This capability is available in Traps management service and requires build 220.127.116.11252 and content update 93. If you are using Cortex XDR, Palo Alto Networks plan to have a similar fix in the next maintenance release for the Cortex XDR 7.0 agent.
Traps Agent 6.1.4 Addressed Issues
Fixed an issue on Linux endpoints related to exploit protection modules and Traps services where spikes or continuous loading of processes on a system event led to the Traps agent being out of sync with the Linux server state regarding processes and permissions.
Fixed an issue that occurred after a malware scan completed where Traps reported duplicate scan completion events to Traps management service.
Fixed an issue on Windows endpoints where the DLL hash calculation caused high memory consumption on the endpoint.
Fixed an issue on Windows endpoints where Traps could not generate a Tech Support File if you use Roaming User Profiles.
Fixed an issue that occurred during a Live Terminal session where you could not explore the file system if an exception occurred during data retrieval.
Fixed an issue on Linux endpoints where Traps reported that Ubuntu 12 was incompatible with the kernel module.
Fixed an issue on Windows endpoints where installing, upgrading, or uninstalling the Traps agent software did not complete when services took longer than 30 seconds to start or stop.
Fixed an issue on Windows endpoints where Live Terminal configurations were not protected by Agent Tampering Protection.
Traps Agent 6.1.3 Addressed Issues
Fixed a memory leak that occurred on specific network hardware during event collection of network events.
Fixed an issue where ESM environments migrating to Traps management service cloud-based environments could not install Traps agent version 6.1.2 on Linux endpoints. Now in version 6.1.3, you can create an
Upgrade from ESMagent installation package for Linux in Traps management service, upload it to ESM, and send out to all your agents for upgrade.
Fixed a compatibility issue with Traps and MicrosoftAppV, which caused the endpoint to become unresponsive sometimes.
Fixed an issue in the Traps upgrade process on Linux endpoints, where you had to restart the agent after Traps upgrade in order for the new kernel module to be updated.
Fixed an issue on Windows endpoints, where sometimes the Traps agent would time-out during certain file operations.
Fixed a performance issue that occurred when event-log messages were parsed without caching.
Fixed an issue on Linux endpoints, where injecting into processes caused them to hang.
Fixed an issue where Windows endpoints overloaded the endpoint kernel stack and became unresponsive if a large number of drivers, including Traps, attempted to load at the same time.
Fixed a performance issue that occurred due to redundant file calls when Traps tampering protection was enabled.
Fixed a compatibility issue where an agent running Traps version 6.1.2 could not connect to the Traps management service if the Palo Alto Networks firewall deployed in the environment was set to enable SSL Decryption.
Fixed a performance issue of increased compilation times for users on Mac endpoints running Traps.
Fixed an issue where the digital signer of the file was missing in the security event details extracted from the Traps endpoint during a scan.
Fixed an issue on Windows endpoints where Ransomware security events queried relative files by the file name instead of the file path.
Fixed an issue where after restating the endpoint, Traps became incompatible with the macOS running on the endpoint.
Fixed an issue where the Signer was not being reported back to Traps management service as part of the security event during the scanning of files on Traps endpoints.
Traps Agent 6.1.2 Addressed Issues
Improved Traps performance on Mac endpoints during heavy processes load on the endpoint.
Fixed an issue where delayed, cached, queued, or heavy loads of data collection events cause a high memory usage for the cyveraservice.exe process.
Fixed an issue where the Traps agent console reported the agent is Connecting instead of Disabled after Exploit and Malware policies were disabled through the Traps management service.
Fixed a high memory consumption issue of the trapsd process on Mac endpoints.
Fixed an issue that occurred when starting a VDI session, where the Traps console and Traps tray icon appeared to be disabled event though they were fully functional.
Fixed a compatibility issues for the ROP Mitigation module with the vstfpd service.
Improved the logic of identifying logged-in users so that Traps relies on the user SID, a unique Windows user security identifier, when the usernames in SAM and UPN accounts are different.
Fixed an issue where a Traps agent would get disconnected from the Traps management service during a Live Terminal session. This occurred when Traps management service was downloading encrypted files (EFS) from Windows endpoints.
On Linux endpoints, uninstalling Traps using the uninstall script fails if the trapsd server is down.
Fixed an issue on Linux endpoints, where Traps could excessively print log messages to system logging infrastructure.
Allowed for configurable timeout for policy updates on Linux endpoints.
Traps Agent 6.1.1 Addressed Issues
Fixed an issue on endpoints running Windows 7, where a Traps agent could halt when scanning loaded DLL files.
Fixed a performance issue that occurred when Traps was calculating a process hash.
Fixed a performance issue that occurred when Traps attempted to open a corrupt document.
Fixed an issue where Mac endpoints running Traps 6.1 and Symantec would freeze upon shutdown.
Fixed a driver compatibility issue on Mac endpoints running Symantec.
Fixed an issue that occurred on Windows endpoints whose Agent Setting profile was configured to disable access to the Traps console on the endpoint. If you tried to access the console anyway, the system message wrongly stated that Traps has been disabled instead of indicating that your access to the Console has been disabled.
When enabling Traps to monitor and collect data for sharing EDR data with other Cortex apps, Traps could halt if it attempted to reference a process that has already ended.
Fixed an issue where the Traps agent reported to be working with the new content version even though the content update failed on the endpoint.
Fixed a compatibility issue with CFG exports suppression on endpoints running Windows 10 RS2 Version 1703 (Build 15063) and later.
Fixed an issue where a Mac agent that became unlicensed could not be uninstalled using the default system password.
Now for Behavioral Threat events on Mac and Linux endpoints, the Analysis tab of the security event displays the correct year in the timeline.
Fixed an issue on Windows endpoints where the incorrect content version number may be reported back to Traps management service in case of a communication error.
Now you can upgrade Mac endpoints running Symantec to Traps 6.1.X version.
Fixed an issue in non-persistent VDI environments, where Traps agents on Windows endpoints were unable to connect to the Traps management service but the endpoint details on Traps management service displayed an active status.
Fixed an issue where events where the evaluation of behavioral threat events caused high CPU usage on Windows endpoints.
