    Hi All,

    Received file (prozellanfabrik_frauenthal_gesmbh.cab) in the email attachment.  After extracting the .cab file found one .scr file, when double click which opened in MS Word by default and then system got sluggish and hanged.  And after few moment all the word, excel, ppt, pdf, text and zip files extension changed with “ubvleva”.  Then we have tried to open file by renaming the extensions to original but none of the file accessed, even tried system restore

    We have SEP 12x at our office which doesnt catch the Virus/Torjan at that moment.  But at evening the Virus got detected by auto protect automatically and pop-up with virus name called “Dowloader.Ponik” for the same virus file which I got through email, which I have kept for assessing/R&D.

    Kindly help to decrypt those files.

    Regards!

    Hi Kashif.ali,

    The posts above are accurate.  What you are describing is a major malicious spam campaign that is currently underway.  The recommendations in https://www-secure.symantec.com/connect/blogs/support-perspective-ctb-locker-and-other-forms-crypto-malware will help you protect yourself.

    I see the malicious file in your instance is now detected- warn your end users to expect more of these malicious files to arrive in the coming days.  Ensure that they are not opened- submit them to Security Response if they are not detected.

    I hate to say this but... Please update yourself (and other staff) with email safety lessons - NEVER, EVER run any attachments from unknown source.

    I do really hope you have a very good backup to restore these files because they are forever lost.
