Note on "undelivered parcel" of the Polish post
At the end of March, reported about the first campaign, whose aim was to infection of a users encryption software files (CryptoLocker). Several days ago the same incident described Niebezpiecznik and the Foundation Secure Cyberspace. By contrast:
- Today reported a us Reader Stephen (thank you for the info) that was a victim of the same spam.
- And Norbert, who has access to your important files.
All of these recent campaigns, which use the image of the Polish post to one common background. Someone on their victims trying to earn considerable money low cost price.
"The courier has not provided the shipment to the notification number RR2188538397PL * to the address 11.07.2015 *, because no one in this time. Please see information on the ship and go to the post office to receive a package. "

It is important to know that any devices connected to the USB ports, as well as network drives are scanned by Crypl0L0cker'a in order to search for "desired" file extensions, which will be encrypted strong key RSA algorithm 2048-bit. Recover files is "almost" impossible – but more on that below.
We adhere to before the ransomware, which encrypts files on the user's computer and requests made using ' Bitcoin ' ransom for their recovery. Especially these words to the victims, which were already dealing with "file extension" or restore data from a backup.
Uczulamy also, to use a decent antivirus software. A very interesting component of the competition to protect against Lockerami out Polish Arcabit software. The cube under the name SafeStore has been designed to protect against all pests MoneyPack family coding data, and so the Ransomware and Locker'y. It works as follows: when the virus scanner checks every "touched" the file, regardless of who (what) it opens the/writes and if the file extension is compatible with masks (doc, docx, docm, xls, xlsx, xlsm, ppt, pptx, pps, ppsx, pptm, ppsm, odt, ods, odp, rtf, pdf, abw, dbk, dps, et, gsc, wps, jpg, jpe, jpeg, png, bmp, tif, tiff, psp, psd, wpd, sxw, sxc, sxd, wks, wk1) is a copy of the file is made before modifying it and goes to the list in the protection of the SafeStorage (you can find it in the "Tools" ). Each new version of the file is also a puppet to SafeStorage, so in a sense, SafeStorage also acts as backup-chwilówki. Files in SafeStorage are held for 3 days, then are deleted, but the files again "affected" will be again included in the list of SafeStorage.

If all of these points have failed and the files and so were encrypted, the method of their recovery is one and not completely effective. Use the tips in the "DecryptCryptoLocker service deszyfrująca files after CryptoLockerem infection".
