    Deep Behavioral Inspection causes cmd crash

    in ESET Endpoint Products

    Posted

    On computers with EEA installed, the window appears a few seconds after executing cmd, and then the window closes automatically.
    If I disable Deep Behavioral Inspection or add c:\windows\system32\cmd.exe to the exclusion list, cmd will run normally.

    Tried pre-releases update, still the same situation.

    What can I do to solve this problem?

    Windows 10 22H2 x64, EEA 11.0.2044 (Deep behavioral inspection support module 1150)

    Blocking Specific Programs

    in ESET Inspect On-prem (Detection and Response)

    Posted

    Thanks @jia_yang reply.

    I mentioned AnyDesk just as an example. Using a firewall to block network connections or blocking hash-based file are among the methods. However, personally, I don't consider these good approaches for users of ESET Inspect.

    Given that using ESET Inspect allows us to detect when a client executes certain programs and ESET Inspect also has the capability to block files, why are there limitations on functionalities like KillProcess?

    For instance, within ESET Inspect's built-in rule: "AnyDesk Remote Desktop Silent Installation [D0443]", this rule can detect silent installations of AnyDesk, and it's set to perform actions like KillProcess. However, when this event is triggered, it doesn't block the installation or execution of AnyDesk. Shouldn't it be blocked immediately if someone unauthorized attempts this?

    Since this will require further investigation and logs, please raise a support ticket.

    For sure we'll need the following for a start: 1, ESET Log Collector logs from the machine, 2, a Procmon log from time when the issue occurs created with Self-defense disabled. Anyways, colleagues from technical support will provide exact instructions and help you troubleshoot the issue.

    I submitted a support ticket last Friday, but no any response so far. The logs you mentioned is below, can you see what the problem is? Or pass it on to the appropriate person? Thanks!

    in ESET PROTECT On-prem (Remote Management)

    Posted · Edited by sdnian

    I've an ESET PROTECT v10.0.1128 and ESET Bridge 1.0.37. All clients  use this proxy server. 

    After the antivirus software been installed, it can't been activation. I found some logs..

    Access.log:

    172.1.3.51 - - [04/Feb/2023:15:19:19 +0800] "CONNECT edf.eset.com:443 HTTP/1.1" 502 150 "-" "-"

    Error.log:

    2023/02/04 16:03:24 [error] 6892#7452: *954 proxy_connect: edf.eset.com could not be resolved (2: Server failure), client: 172.1.3.211, server: , request: "CONNECT edf.eset.com:443 HTTP/1.1", host: "edf.eset.com:443"
    2023/02/04 16:03:24 [error] 6892#7452: unexpected DNS response for edf.eset.com

    I run a test in the ESET PROTECT server.. Get 502 error.

    > curl.exe --proxy hxxp://172.1.3.105:3127/ https://edf.eset.com/edf 
    curl: (56) Received HTTP code 502 from proxy after CONNECT

    But if don't use proxy.. the connection is fine.

    > curl.exe https://edf.eset.com/edf 
    <?xml version="1.0" encoding="utf-8"?><ecp:message xmlns:ecp="hxxp://www.eset.com/2012/02/ecp"><ecp:response><code>20101001</code><message>invalid http method</message></ecp:response></ecp:message>

    So.. how to fix the Bridge DNS resolved problem?

    Thank you!

    Hello,

    Over the past two days, different customers have been responding that after installing EEA/EFSW, the product activation failed with the error code: ACT.0. I tried to connect to https://edf.eset.com/edf and it looked fine, and I got the following content:

    <?xml version="1.0" encoding="utf-8"? ><ecp:message xmlns:ecp="hxxp://www.eset.com/2012/02/ecp"><ecp:response><code>20101001</code><message>invalid http method</message></ ecp:response></ecp:message>

    How to solve this problem? Thanks!

    EEA can't apply policies settings

    Hello @sdnian

    does the issue persist?

    If yes please check the Configuration support module version on the agent if it is up to date.
    Which version is used on it, when it fails? 

    Can you provide us with the full log from the agent to see the whole picture?

    Peter

    @Peter Randziak The issue persists. I've collect logs, please take a look if what kind of wrong?

    EEA can't apply policies settings

    in ESET PROTECT On-prem (Remote Management)

    Posted

    I have a Windows 7 SP1 been installed  Agent 9.0.1144 and EEA 9.0.2046. After the installation, it can connect to ESET Protect, and I can see the successfully applied policies on the console, everything are normal so far.

    However, when I check the settings from the client, there is no policies settings been applied.

    Uninstall and reinstall Agent and EEA, the issue is still exist.

    There is an error in the trace.log:

    Error: CEssConnectorModule [Thread 103c]: Set policy failed: CNodcommChannel: Send request failed with 14, Command failed - Make sure that Agent runs with Administrator privileges.

    How to fix it?

    Connecting https sites is very slow and may even time out

    in ESET Endpoint Products

    Posted

    Computers are controlled by a firewall and only a limited number of specific websites are accessible. After installing EEA 7.3.2039, using a browser to connect to https sites is very slow and may even time out.

    If I turn off the SSL/TLS protocol filtering, it will be back to normal.

    Does EEA's SSL/TLS protocol filtering feature need to connect to certain IP addresses? Or how can I fix this?

    Trace message - Invalid utf8 leading byte

    Thanks for logs. We are currently not sure but most probable reason is that either message is cut-off (there is maximal length) in wrong place and thus rendering string as invalid, or there is a problem with conversion of data as reported by system.

    This issue seems to have occurred after I upgraded ESMC 7.2, maybe there is a tweak or something in the new version that is causing this problem.

    Unfortunately it seems to be an issue in ESMC Agent not able to handle trace messages. Any chance full msiexec log from those installations is available (in standard AGENT logs directory) for analysis? There is probably issue with encoding - I guess that installation was performed on operating system with non-latin locale?

    This is one of the clients that failed to upgrade, the error message is in Chinese, this kind of message also appeared before, why this is an Invalid utf8 leading byte?

    Can't block YouTube from Chrome

    in ESET Endpoint Products

    Posted · Edited by sdnian

    I'd like to block https://www.youtube.com/. In URL ADDRESS MANAGEMENT, I add a record *.youtube.com. I've tried IE/Firefox/Vivaldi, https://www.youtube.com/ been blocked. But if I use Chrome to browse https://www.youtube.com/, EEA don't block it.

    If I block others domain, for example: *.facebook.com, then https://www.facebook.com/ been blocked in IE/Firefox/Vivaldi/Chrome.

    EEA version: 7.2.2055

    How can block YouTube form Chrome?
