Accidentally opened suspicious attachment

[heliojmsemedo]

  

So I got this email

The attached HTM is this

<frameset onload="document.location.href=window.atob('aHR0cHM6Ly90cmFja2VyMjAyMS5tZS81aDl3eWg/MTU2MzIxMTgzNDcyMTM0MTI0IA==');" />

That is a base64 string that decodes to

https://tracker2021.me/5h9wyh?156321183472134124

I did request this through Postman and noted it's a page with text about Elon Musk helping you get rich or something, basic elonscam give me 0.0005 bitcoin i'll give you 0.05 bitcoin but I'm unconfortable with how basic this seems, I'm thinking there's more to it, can someone help? I see some google analytics scripts and some other tracking scripts such as facebook's, is there anything else here? I did accidentally open the thing on my browser but closed it right away

Hello heliojmsemedo and welcome to Malwarebytes, Disable smart screen if it interferes with software we may have to use: https://support.microsoft.com/en-us/microsoft-edge/what-is-smartscreen-and-how-can-it-help-protect-me-1c9a874a-6826-be5e-45b1-67fa445a74c8 Please remember to enable when we are finished.... Next, Disable any Anti-virus software you have installed if it stops software we may use from working: https://www.bleepingcomputer.com/forums/t/114351/how-to-temporarily-disable-your-anti-virus-firewall-and-anti-malware-programs/ Please remember to enable AV software when we are finished running scans.... Next, Lets grab some logs and see whats going on, continue with the following: If you do not have Malwarebytes installed do the following: Download Malwarebytes version 4 from the following link: https://www.malwarebytes.com/mwb-download/thankyou/ Double click on the installer and follow the prompts. When the install completes or Malwarebytes is already installed do the following: Open Malwarebytes, select > small cog wheel top right hand corner, that will open "settings" from there select "Security" tab. Scroll down to "Scan Options" ensure Scan for Rootkits and Scan within Archives are both on.... Close out the settings window, this will take you back to "DashBoard" select the Blue "Scan Now" tab...... When the scan completes quarantine any found entries... To get the log from Malwarebytes do the following:   Open Malwarebytes Click on the Detection History tab > from main interface. Then click on "History" that will open to a historical list Double click on the Scan log which shows the Date and time of the scan just performed. Click Export > From export you have two options: Copy to Clipboard - if seleted right click to your reply and select "Paste" log will be pasted to your reply Text file (*.txt) - if selected you will have to name the file and save to a place of choice, recommend "Desktop" then attach to reply   Please use "Text file (*.txt), then name the file and save to a place of choice, recommend "Desktop" then attach to reply Next, Download AdwCleaner by Malwarebytes onto your Desktop. Or from this Mirror   Right-click on AdwCleaner.exe and select http://i.imgur.com/Spcusrh.pngRun as Administrator (for Windows Vista, 7, 8, 8.1 and 10 users) Accept the EULA (I accept), then click on Scan Let the scan complete. Once it's done, make sure that every item listed in the different tabs is checked and click on the Quarantine button. This will kill all the active processes Once the cleaning process is complete, AdwCleaner will ask to restart your computer, do it After the restart, a log will open when logging in. Please copy/paste the content of that log in your next reply Next, Download Farbar Recovery Scan Tool and save it to your desktop. Alternative download option: http://www.techspot.com/downloads/6731-farbar-recovery-scan-tool.html Note: You need to run the version compatible with your system (32 bit or 64 bit). If you are not sure which version applies to your system download both of them and try to run them. Only one of them will run on your system, that will be the right version. If your security alerts to FRST either, accept the alert or turn your security off to allow FRST to run. It is not malicious or infected in any way... Be aware FRST must be run from an account with Administrator status... If English is not your primary language Right click on FRST/FRST64 and rename FRSTEnglish/FRST64English   Double-click to run it. When the tool opens click Yes to disclaimer.(Windows 8/10 users will be prompted about Windows SmartScreen protection - click More information and Run.) Make sure Addition.txt is checkmarked under "Optional scans"   Press Scan button to run the tool.... It will make a log (FRST.txt) in the same directory the tool is run. Please copy and paste it to your reply. The tool will also make a log named (Addition.txt) Please attach that log to your reply. Let me see those logs in your reply... Thank you, Kevin....

Ok that's a lot to do but did you take a look at what I sent? Before I go on installing any programs and disabling smart screen I wanna be sure we're on topic here, sorry, that looks like a scripted response.

[kevinf80]

Hello heliojmsemedo

Yes I looked at what you sent, and yes I gave you a scripted reply. If you look at the my request to disable smart screen and your AV security, that is only necessary if they interfere with scans I ask you to run, if they dont then leave them as is...

tracker2021.me is a malicious website that will cause major problems you and for your system if you had been successfully diverted. Malwarebytes and or Malwarebytes browser guard will defend against that website and any browser hijackers or dodgy emails that try to send you there..

The scripted response is what I use to get a full overview of your system, i need to know exactly what is going on, FRST will tell me that after Malwarebytes and AdwCleaner have removed anything malicious you may have picked up.

I`m a volunteer here at Malwarebytes, my time is very valuable and i try to use it wisely.

Thank you,

Kevin..

[heliojmsemedo]

Alright, what's the objective of this tracker2021.me website? As in what is it trying to do?
I'm sending aAddition.txtttached the files as you requested but there was no request for a restart and instead of a log window ADW cleaner simply showed me a button to open the log file that cointained this:

Did you make this setting in the hosts file..?

2018-09-15 08:31 - 2020-08-23 19:32 - 000000854 _____ C:\WINDOWS\system32\drivers\etc\hosts
172.0.0.1 testlocationar.com

[heliojmsemedo]

My memory is fuzzy but that I think that might have been for a project I was working on. The name is familiar

[kevinf80]

Are you wanting to keep that setting..?

[heliojmsemedo]

Nope, I just removed it from the hosts file

[kevinf80]

Hello heliojmsemedo,

Regarding tracker2021.me website or any other such websites:

Once you have visited or have been redirected to a malicious or hacked website code can be executed on your PC,  that code can redirect you to other malicious sites, download malware to your computer, or scrape personal information from your computer.

Access to bitcoins, what you do with bitcoins or how you bank them is a current favorite of malware writers, can be easier to make money than using ransomware on personal systems...

Continue as follows:

Please download the attached fixlist.txt file and save it to the Desktop or location where you ran FRST from. NOTE. It's important that both files, FRST or FRSTEnglish, and fixlist.txt are in the same location or the fix will not work. NOTICE: This script was written specifically for this user, for use on this particular machine. Running this on another machine may cause damage to your operating system that cannot be undone. Run FRST or FRST64 and press the Fix button just once and wait. If the tool needs a restart please make sure you let the system restart normally and let the tool complete its run after restart. The tool will make a log on the Desktop (Fixlog.txt) or wherever you ran FRST from. Please attach or post it to your next reply. Note: If the tool warned you about an outdated version please download and run the updated version. NOTE-1: This fix will run a scan to check that all Microsoft operating system files are valid and not corrupt and attempt to correct any invalid files. NOTE-2: As part of this fix all temporary files will be removed. If you have any open web pages that have not been bookmarked please make sure you bookmark them now as all open applications will be automatically closed. Also, make sure you know the passwords for all websites as cookies will also be removed. The following directories are emptied:   Windows Temp Users Temp folders Edge, IE, FF, Chrome and Opera caches, HTML5 storages, Cookies and History Recently opened files cache Flash Player cache Java cache Steam HTML cache Explorer thumbnail and icon cache BITS transfer queue (qmgr*.dat files) Recycle Bin Important: items are permanently deleted. They are not moved to quarantine. If you have any questions or concerns please ask before running this fix. The system will be rebooted after the fix has run. Next, Download "Microsoft's Safety Scanner" and save direct to the desktop Ensure to get the correct version for your system.... https://docs.microsoft.com/en-us/windows/security/threat-protection/intelligence/safety-scanner-download Right click on the Tool, select Run as Administrator the tool will expand to the options Window In the "Scan Type" window, select Quick Scan Perform a scan and Click Finish when the scan is done. Retrieve the MSRT log as follows, and post it in your next reply: 1) Select the Windows key and R key together to open the "Run" function 2) Type or Copy/Paste the following command to the "Run Line" and Press Enter: notepad c:\windows\debug\msert.log The log will include log details for each time MSRT has run, we only need the most recent log by date and time.... Thank you, Kevin

 

 

fixlist.txt

[heliojmsemedo]

Thanks for the help, did you notice anything bad on the logs? I see most of the fixlist is concerning the removal of no longer relevant  firewall rules

[kevinf80]

Yes, very suspicious:

AlternateDataStreams: C:\Users\helio\Application Data:6699d3ee8dd9cf775caae782c8f44f03 [394]
AlternateDataStreams: C:\Users\helio\AppData\Roaming:6699d3ee8dd9cf775caae782c8f44f03 [394]

The fix list is also used to clean up remnants of previous settings, firewall settings, system caches, browser caches etc... general maintenance..

[heliojmsemedo]

Sending attached the fixlog. The mser.log doesn't have much, just this:

Hiya heliojmsemedo,

Thanks for those logs, what is the status of the PC now, any remaining issues or concerns..?

Cheers,

Kevin.

[heliojmsemedo]

Looks normal, thanks for the help Kevin! That was all.

[kevinf80]

Hiya heliojmsemedo,

Thanks for the update, good to hear your system is normal again.. Continue to finish up:

Right click on FRST here: C:\Users\helio\Desktop\FRST.exe and rename uninstall.exe when complete right click on uninstall.exe and select "Run as Administrator" If you do not see the .exe appended that is because file extensions are hidden, in that case just rename FRST to uninstall That action will remove FRST and all created files and folders...
