Looking for potential keyloggers

MacBook Pro Mac OS X (10.7.5), activity (10.7.4) monitor, Terminal (2.2.3)

I want to make sure that my computer is not a malicious keylogger infect. The discussions on this site, I searched and found this - keylogger detection - one I didn't not really it, especially the parties on the use of Terminal or what they call the grain or 'man', but the marked resolved commentary concludes that keyloggers can only get (or most likely) on manually or through sharing services (which I assume are under system preferences > sharing which I don't use anyway).

Well, just to be sure, I've been watching the programs in my activity monitor:

It's a little hard to follow because the list keeps getting longer or shorter. I found this list - deals with the Description of Mac OS X: by triviaware - and in her view, none of these programs are malicious.

However, some of the programs in the activity monitor are not listed on the Web page I found (e.g. detection device, kernel_task, Safari Web Content and any program starting with Sophos) and some of them seem to appear more than once in the activity monitor (e.g. CVMCompiler, distnoted, launchd, UserEventAgent, xpchelper).

My question is:

  1. Can anyone recommend a method of detection of keyloggers?
  2. One of these programs look suspicious?
  3. Can someone explain Terminal?

Sophos is so-called "security software" that was installed, personally I don't think that you need, but it's your call. OS X will try to prevent known malware to run so the anti-virus scanner is probably not necessary (normally, they waste resources like RAM, time processor that you can be used elsewhere). Some companies require these elements to be installed, it might help if you share a lot of files with Windows users.

kernel_task is the first process, the system starts at the start - don't mess with it: it's 'zero process' everything else works essentially on top of that.

If you search around you will find other ways to possibly detect keyloggers, frankly they are all involved & you can be better to erase the OS & reset all passwords if you believe that the machine is compromised.

You can get better help here, explaining why you think a key logger is installed, OS X should be safe if you follow some basic guidelines as to avoid to use the administrator account to work inside (using a standard user account instead) and do not install any software randomly from the internet.

If the Mac is left unattended in a public place, anyone may be able to install the software if the admin password is known. Unattended Mac should require a password for login, be stopped when left or have the screensaver settings to require a password.

The "kextstat" command in this post you linked to bows "kernel extensions" are very low-level 'plugins' who have the ability to modify the operating system for all users. Keyloggers can use it as a method to access the key, but there are probably other ways that a key logger can always run.

Charles Minow suggested that the list of kextstat was read, looking for lines that do not contain «com.apple...» »

In the Terminal, enter

kextstat

  • What tools do you use to determine the Web sites that your customers are looking for?

    We all know and understand what talking about travel buyers.  Various research estimated that up to 90% of the search is taking place for most online and before a prospect decides to talk to a sales representative.  A session of the CEB Dreamforce I attended to referenced that the average prospect is looking for 10 different sources of information guide their decision to buy and the seller's Web site is just a trust least. (I'm paraphrasing from memory, so don't be too hard on me if something is disabled) It would be useful to know if any of you use tools that help to discover some of these other websites which is underway in addition to our own.  Would love to know what works.  Thank you!

    Hi Joseph, you will have problems on this one.  You used to be able to make a number of cough... cough... not strictly beyond the means of the Council.

    In the old days, you can use techniques such as SpyJAX, etc. for this - but they don't work anymore

    I had a friend that I had used to work with who has worked on a way to push this information automatically in an another marketing automation platform (although you could have done in Eloqua) and adds it to their lead, scoring model.

    While on the surface it looked like a really cool idea actually it didn't really prove anything - I digress...

    As you quoted the Dreamforce event you attended at the prospect of average search 10 different sources, I think I see what you're trying to identify, you want to know which party 3 different sites of your potential customers are searching on and then find a way to help guide a favorable outcome regarding your product through their research.

    First off you should check out some of these Tools to listen to social media.  Here those are all free, but you get others who will analyze linkedin, forums, etc.  Check out mentions of your competitors brand names and products too.

    Now you have a list of the various sources that are using your competitors, you now have your target.

    You now have your ammo.  You must develop a program of customer awareness.  Which is exploit your product advocates, these are current customers, who are very credible, extremely knowledgeable and love your product for its features.  There are a number of tools out there, that you can use for this.  One of the guys eloqua former albums, Mark organ, developed a software that will help you do just that.  Its platform is called influitive.  I have been an advocate of product before on this platform and believe me, it's the company.  I would probably spend at least one hour per week responding to the challenges posted for me.

    For example the company in question had a few targets in the groups they knew prospects would ask "which platform is better, X or Y?  I would join this group, they would give me a few points and then they would issue me any time challenges that this type of issue has come.  Because I had very deep knowledge on both platforms, I could give an answer that is hinged at the question of the person.  I was a 3rd party source, not a salesman saying "I work for company X and my product is the best, call me my details are...» ", this meant that I had a much greater impact in my opinion.

    Enter the power of Eloqua.  You get your defenders of a link to your Web site and give them their own unique query string.  All you need to do is pull a report from query string at the end of the month and voila, you not only what you were originally looking for, but your own clientele that contribute to your marketing effort.

    I hope this helps...

  • Looking for dynamic PDF (page-flipping) Viewer for my website

    I wasn't sure if this or the PDF forum is a better place for this question, but...

    I am looking for a PDF document for visitors to my website on a page that contains nothing but. Ideally, it would be an experience as dynamic as possible, with some animations-flipping of page (at least). As a virtual magazine.

    I researched what could exist to help me there and found things like this and this.

    Obviously, they are not all created equal and we could go crazy to try. So if someone has already been through this and can help a guy out, much appreciated. Ideally, I'm looking for something that obviously works very well on all devices, a smooth rather than entertainment in the staircase and allows the touch sliding (IE, iPad).

    Doesn't have to be freeware (I'll pay if it's worth the hump), though of course free it better than non-free.

    Thank you!

    I used this solution a bit backwards: Turn.js: the page flip effect in HTML5

    However, licensing is not clear for version 4. You may want to contact the developer about potential costs: blasten (Emmanuel Garcia) · GitHub

  • mirroring AirPlay look for apple tv

    Since the iOS 10 update on iPhone and iPad, it seems that I can't find my AirPort Express for streaming music on my stereo.  When I click on AirPlay Mirroring it only looks for AppleTV and never find my Express.  Someone else has a similar problem?  Is there another setting I'm missing?

    When I'm in the Spotify application, there is a button for devices and this app can find the Express (on iOS 10), but my SiriusXM app doesn't have this same feature.

    Thank you!

    Since the iOS 10 update on iPhone and iPad, it seems that I can't find my AirPort Express for streaming music on my stereo.  When I click on AirPlay Mirroring it only looks for AppleTV and never find my Express.

    AirPlay Mirroring and AirPlay streaming are two different things. With iOS 10, AirPlay Mirroring is accessible via the control panel. AirPlay Streaming has been integrated in the music app.

    Apple provides a free user guide to help users to familiarize themselves with the features of the new version of the iOS.

  • Problems with three fingers looking for preview

    Hi all

    So I've upgraded to Mac OS Sierra the other night and it was absolutely great so far. However, there is a feature I noticed is either absent, either turned somewhere off the coast, and it is three fingers look upward in the preview. I'm at school and do a lot of my reading on a PDF in preview, and yes I just came across a few words that I don't know the definitions to. In the past, three fingers look has been one of the best features for its quick access to definitions. This is something I really miss and hope that it will be always possible somehow.

    Now, I noticed that it only worked in other applications as well, I went to settings and looked for the feature. I was able to find it in the settings of the Trackpad and he turned his back. That seems to have worked for just about every other app except Preview. If anyone has solutions to this problem, I'm all ears!

    Thanks in advance guys!

    It works for me in preview. However, it took several 3 finger taps to finally get the context menu with 'Look Up' inside to provide the result below.

  • Looking for hope in the restoration of my iMac

    My iMac HD has failed, and I took it to Apple to get it replaced. I had a Time Machine backup on an external hard drive Seagate. But my iMac just not see the backup drive Seagate. I don't know if there is a trick to getting the Seagate HD displays. It does not show in Finder or in disk utility. But when the iMac HD was not, and I looked for ways to restore, I saw a Time Machine backup date. Now, I can not see the drive. Even though I have the music and pictures stored in iCloud, all my apps are now gone. I don't know where to start. I was a fool to trust Time Machine? This is literally disastrous for me, and I don't know where to start. What I need, is to see this backup disk somewhere BTW, I plugged on another iMac and he did not see it either. Is there some magic for Seagate HD?

    Some things you can try:

    * Open the Finder preferences (under the Finder menu, top left of your screen). Make sure that on the general tab, the boxes are ticked for hard disks and drives, to show them on your desktop. Otherwise, they won't be visible.

    * Try a new cable. The cable went wrong.

    * Open disk utility when the drive is connected. You can see on the left hand side of the disk utility? If you see an external drive, try to mount in disk utility. If you can ride, the files are available? If this isn't the case, you can run disk utility to try to fix it.

    * Seagate's data recovery services.  http://www.Seagate.com/services-software/recover/ first of all, you can download their software and try it for free. If it can find files on the disk, you can then purchase the license of their recovery software to use to recover your files from the Seagate drive. Alternatively, he can perform the data recovery for you (with supplement). The details are at this link.

    I'm sorry it happened, I wish you good luck.  It seems that your problem could not Time Machine, which is actually a very good backup program; but rather, your external drive seems to have a problem. This happens to all readers subsequently, no last forever and that's why I try to keep at least two backups, each with a different method. For example, one with Time Machine, the other using software such as "clone" (such as SuperDuper, CCC etc.). It is good that you use the cloud at least. I hope that you can recover your files.

  • Hello, I'm looking for time machine to my iphone more than 6

    Hello, I'm looking for time machine to my iphone more than 6

    There is no time Machine to an iOS device. They are saved to the iCloud or iTunes on a computer; Time Machine can then save the backup to a computer, but he can't save a device iOS directly.

  • You are looking for a simple auto-upload / sync solution

    Hello!

    Our House is the proud owner of several Apple devices, together, we have 2 MacBooks, 2 iPhone and an iPad. Devices are distributed over more than 2 Apple ID, we want to keep it this way.

    But, as we both take a lot of pictures it is always a hassle to keep track of the best of them so that we are looking for an easy solution. I searched a bit already online but seem to be asking the wrong question, in any case, I can't find what I'm looking for so I'll try here now.

    What we would like to have:

    -Pictures of fact on two iPhones are automatically downloaded / synchronized to one place, wherever we are.

    -This place should ideally be in our House (so preferably not cloud)

    -This place should also be easily accessible from a computer at home so that we can see both the photo when we want and send us some grandmother for example.

    Does anyone have or know a Setup program as described? We are willing to invest and have considered purchasing a Synology appliance for our backups etc already. One of the iPhone is an iPhone 4 which is still ok, so if possible, we would like to keep for a while, the other is an SE. The two MacBook are completely up to date.

    Thanks in advance!
