Ransomware - Trojan.Agent.ED, Trojan.Dorkbot.ED etc


Davexxx

Recommended Posts

A Win7 Pro x64 Laptop has become infected over the past couple of days (very slow operation; protected by Malwarebytes & Vipre).   Malwarebytes log extracts are appended, with the Trojan identifications including:

Trojan.Agent.ED
Trojan.Agent.0BGen2
Exploit.Drop.70
Trojan.Dorkbot.ED

These files are on the Windows desktop (and elsewhere):

HELP_DECRYPT.HTML
HELP_DECRYPT.PNG
HELP_DECRYPT.TXT
HELP_DECRYPT.URL

And "The Windows Security Center can't be started" - MicrosoftFixit50981.msi doesn't work, nor can 'Security Center' services be started.

Any suggestions would be much appreciated.

Dave.

Hello,
    
 
They call me TwinHeadedEagle around here, and I'll be working with you.
 
     
    
Before we start please read and note the following:

  • Limit your internet access to posting here, some infections just wait to steal typed-in passwords.
  • Please be patient. I know it is frustrating when your PC isn't working properly, but malware removal takes time.
  • Don't run any scripts or tools on your own, unsupervised usage may cause more harm than good.
  • Do not paste the logs in your posts, attachments make my work easier. There is a More reply options button, that gives you Upload Files option below which you can use to attach your reports. Always attach reports from all tools.
  • Always execute my instructions in given order. If for some reason you cannot completely follow one instruction, inform me about that.
  • Stay with me to the end, the absence of symptoms doesn't mean that your machine is fully operational.
  • Note that we may live in totally different time zones, what may cause some delays between answers.
  • Do not ask for help for your business PC. Companies are making revenue via computers, so it is good thing to pay someone to repair it.
  • If I don't hear from you within 3 days from this initial or any subsequent post, then this thread will be closed.

:excl: I can't foresee everything, so if anything unexpected happens, please stop and inform me!
:excl: There are no silly questions. Never be afraid to ask if in doubt!

Your PC seems to be infected with Cryptowall virus. More info here --> http://www.bleepingcomputer.com/virus-removal/cryptowall-ransomware-information

 

We can remove the infection, but encrypted files will still be unusable.

 


 

 

Please download Farbar Recovery Scan Tool and save it to your desktop.
 
Note: You need to run the version compatibale with your system. 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.

  • Double-click to run it. When the tool opens click Yes to disclaimer.
  • Press Scan button.
  • It will make a log (FRST.txt) in the same directory the tool is run. Please attach it to your reply.
  • The first time the tool is run, it makes also another log (Addition.txt). Please attach it to your reply.

FYI: Laptop seemed to freeze after a file deletion (icons disappeared from desktop), so I forced a shut-down via power switch.

1) Reboot opened "Windows did not shut down successfully" page, so selected "Start windows normally"

2) After launch: a) "The Windows Security Center can't be started" dialog appeared via Open Action Center; b) also HELP_DECRYPT.PNG (only) was returned to the Windows desktop.

Laptop seems quicker now.

Yes, PC should be fine now :)

 

Thank you.
 
 
 
Glad I could help. We will delete all used tools and I'll give you some tips to harden your security and learn how to protect yourself :)

icon_exclaim.gifMUST READ - general maintenance:

The Importance of Software Updating:

 

 
In order to stay protected it is very important that you regularly update all of your software. Cybercriminals depend on the apathy of users around software updates to keep their malicious endeavor running.
 
Operating systems, such as Windows, and applications, such as Adobe Reader or JAVA, are used by tens of millions of computers and devices around the world, making them a huge target for cybercriminals. Downloading updates and installing them can sometimes be tedious, but the advantages you get from the updates are certainly worth it.

Recommended additional software:

 
 
icon_arrow.gifTFC - to clean unneeded temporary files.
icon_arrow.gifMalwarebytes' Anti-Malware - to scan your system from time to time in search for malware.
icon_arrow.gifMalwarebytes' Anti-Exploit - to prevent plenty of mostly exploited vulnerabilities.
icon_arrow.gifMcShield - to prevent infections spread by removable media.
icon_arrow.gifUnchecky - to prevent from installing additional foistware, implemented in legitimate installations.
icon_arrow.gifAdblock - to surf the web without annoying ads! 
 
 

Post-cleanup procedures:

 

 
Download DelFix by Xplode and save it to your desktop.

  • Run the tool by right click on the 51a5ce45263de-delfix.png icon and Run as administrator option.
  • Make sure that these ones are checked:
    • Remove disinfection tools
    • Purge system restore
    • Reset system settings
  • Push Run.
  • The program will run for a few seconds and display a notepad report. You do not need to attach it.

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.

Malwarebytes Anti-Rootkit: "An error has occurred: Scan failed!" on two attempts (updated successfully) ...

 

1) Malwarebytes Anti-Rootkit - "Registry Value "AppInit_Dlls" has been found ... Press 'no' button if not sure [selected] ... if tool crashes ... restart and press "yes" ...'

"This version of Malwarebytes Anti-Rootkit requires ... to completely exit ... [OK selected] - "An error has occurred: Scan failed!" and exit

2) Launched mbar.exe - "Registry Value "AppInit_Dlls" has been found ... Press 'no' button if not sure ... if tool crashes ... restart and press "yes" [selected] ...'

"This version of Malwarebytes Anti-Rootkit requires ... to completely exit ..." [OK selected] - "An error has occurred: Scan failed!" and exit
 

So FRST scan not undertaken.

Malwarebytes Anti-Rootkit now runs without premature exit - files attached (mbar-log-2015-02-14 (11-13-34).txt & system-log.txt), plus subsequent FRST scan files (FRST.txt & Addition.txt).

 

The 3 copies of OatboSratl.fox (as per earlier screenshot, with same size, dates & paths) still remain.
