  • How can I tell if my Mac has been hacked v10.10.5

    In 'Window leave Force', there is a flashing line in and out very quickly it was something like: applekit txt... {code

    I have a Mac Book Pro (2013) v10.10.5 with all the updates that are loaded.  My laptop was running a bit slow... freezing for short periods of time when you save a document or work in Photoshop. I moved a large number of my large video files to a backup disk to ensure that I have a lot of space. After the restart, I had that Chrome and Photoshop and Finder running. In the FINDER, I clicked on FILE / NEW WINDOW FINDER and saw the Rainbow Apple "Spinning wheel" for more than 30 seconds while you wait for a new Finder window open.

    More and more impatient, I clicked on the icon Apple and "force quit." In the window to leave, I saw three running applications but also saw a line of red text jump in, then disappear very quickly a few times. I tried to take a screenshot, but couldn't.  The only thing I could catch was something like applekit .txt... {code and that's all I could catch.} I disconnected from the internet, and he stopped.

    You have reason to believe that your mac is hacked?

    Have you recently installed any software suspect?

    Do you have a person with access to your mac that can install something without your knowledge (which requires an administrative password and the access to the system)

    Apart from that you run any type of Mac anti-virus. If so most, if not all have been cited on these forums as points of failure on the Mac and in many, if not all cases of withdrawal of restores them the response and the functionality of the system. Well-known companies AV display the instructions to remove their products. At this time there is no known Mac viruses in the wild, which means no laboratory of titles in the world posted of any finding of a Mac virus that did appear on the internet at this time, please do not confuse this statement with the absurdity of "Mac cannot get viruses.", what I mean , it's "they don't seem still one and mac AV is not nearly as flexible as it is counterpart windows and has been known to cause serious problems and not offer a lot of protection.

    Secondly you are running any 3rd party utility system or network, once again, these products are known to cause problems and are not only necessary are often contrary to the OS X, remove them from your system.

    If you are not sure what you are using please post a report of etrecheck for the volunteers here to look further as to what your system is running, this report contains personal or confidential information. the software was developed by a long time member of this forum in the first goal to help mac users to isolate a problem in their system and has been very successful in doing this, an overwhelming majority of positions where he asked attests to that.

  • How can you tell if a PSG has been included in a call?

    Is there an easy way to tell if a PSG is inserted in a call? Maybe something in the CDR? The destination IP address appears as CUCM, or IP address of the device called?

    I use CUCM 10.5

    Thank you, Tim

    The other thing to do (if it's a phone) is, know what resource PSG 'could' be invoked, from the media resource of the unit group, get the IP address of the resource and make a note of it.

    Make a call to the phone in question, go to the IP address of the phone and click on "stream1", keeping the open call, check what remote IP address, the call is goung to... If we use of the PSG, it should show the IP address f the resource of PSG.

  • May have been wrong to accept the false update yesterday 08/20/11 How can I determine if false update has been installed?

    I was working today on our old XP, Firefox update failed because it was a trick. Yesterday a Firefox updated was approved on our laptop (Vista). How know if we ourselves have infected? Thank you.

    Do not worry. The message "something tried to trick Firefox" is just poorly written. This simply means that Firefox did not verify the certificate of the update and as a result has not installed. Other discussions on this message seem to suggest that this happens quite often and is not, in fact, an indication of "something try to trick Firefox", but a failure of Firefox itself.

    If the update has been installed on the second time, so this time that he managed to check the certificate, as well as the update is ok.

  • Remote procedure call (RPC) - how can I determine if a person has been access to my system remotely? I think someone is.

    I think that my computer is accessed remotely, files and emails being read. I disabled remote access in the Services section and have also disabled Mobile Sync; I did not use one of these services.

    When I took the remote procedure call (RPC) service and open the properties, the logon tab has the section "This account" clicked, "Network Services" typed in the box and a password. I can't change anything on this tab properties. I can't disable the service or disable the 'unattached profile '. How access to this service to make changes and more importantly, how can I confirm that someone logging into my system to remote and checking e-mails, files, etc.. This isn't a networked system, it's my computer in my home office. I am running Vista Ultimate.

    Thanks in advance for your help anticiapted.

    Hello

    Ultimate also has group policies that you can set to lock the machine - GPedit.

    Management of Windows Vista Group Policy (part 1) - see links to part 2 and 3

  • How can I detect if a step has been ignored?

    In an application of C-Sharp, is there a way to detect if a step has been ignored once completed execution?

    ApplicationMgr.GetRunState () and ApplicationMgr.GetTerminationState () do not say if the execution was complete (Nothing ignored) or incomplete (1 or several steps skipped).

    I have to walk through the steps and use the Step.GetRunModeEx () method?

    Hi tlaford,

    You will still need to check each step, but I believe that what you try to do better with the use of Step.ResultStatus:

    ResultStatus property

    Syntax

    Step. ResultStatus

    Data type

    String

    Goal

    Specifies the status string for the step.

    Remarks

    Although you can set custom status strings, this property is usually set to one of the Proprietesde constants.
