Ok, you can substitute whatever agency name you want, but the story is nearly always the same. A little while ago I blogged about Advanced TDS, another Mpack-type clone and mentioned how professional some of the malware creators are becoming.At the other end of the spectrum, we still have a large number of amateurs in the game. The attempts that some of them make in their social engineering trickery is abysmal, to say the least. Take this example of a spam email:
Dear Mr./Mrs. D####### P#######This email was sent to inform you that your complaint case #278250765 filled with the FTC was successfully registered and posted in our Business Sentinel, a business complaint database maintained by the U. S. Federal Trade Commission. The complaint that you have filled is now accessible to certified government law enforcement and regulatory agencies in ICPEN-member countries. Government agencies may use this information to investigate suspect companies and individuals, uncover new scams, and spot other such illegal activities.Because the Internet marketplace is a borderless one, sharing your complaint with government agencies in different countries will help keep the Internet safe. It will also help prevent others from experiencing the problem you have.Information submitted through the online complaint form may also be used in aggregate form to analyze and create statistics, that may be released to the public. This aggregate data will not contain any personal information.Attached you will find a copy of your complaint. Please print a hard copy of the complaint for your records in the upcoming investigation.Thank you for your cooperation and we will keep you informed on the status of our investigation.Federal Trade Commission
It”s not a bad attempt at story writing; the message and wording sound reasonably convincing. The usual story is about a complaint received by the government agency mentioned. Also as usual, attached to the email is a document name along the lines of Complaint_[several random digits].doc. If the receiver falls for the trick and opens the document, they will see the following in the document.
View of opened Word docIf, at this point, alarm bells have not started to go off, then I”m afraid to say you have missed some very clear telltale signs that something is amissFirst there is the schoolboy error in the first word, which would suggest that the author is not from a professional organization. I doubt the scam email crafter meant to say, SBellow is a copy of your original complaint. So, null points for the scammers on the language skills test.Aside from the incorrect choice of words, what about the rest of the document? You”ve got to ask yourself, is a government agency likely to send something of this nature and quality? I would like to think that our taxpayer dollars would give us civil servants able to produce better quality output than this example. So this scam also fails the quality test.Then there is the strange method of embedding a PDF inside a Word document. Now why would anybody want to do that? Why not just send the PDF on its own? Because, as it turns out, what appears to be a PDF file is actually an executable file.Should you try to open the embedded file, you are still given one more chance to avoid being infected.
Prompt after attempt to open PDFWindows warns you that a program called C_Adobe.exe is about to be run. Once again there are clues to be picked up here. Why would a program called C_Adobe.exe run when you attempt to open a PDF file? Plus, C_Adobe.exe does not look like a legitimate application. And, of course, it”s not. It is actually a downloader program that attempts to download other files. The downloaded file drops another file which is an information stealing Trojan horse. Had you clicked on the Run button, I”m afraid you would have just invited a number of threats onto your computer. For most of us, common sense will have saved us from making this mistake. Even better though, a Symantec security product would have caught the whole thing at the very beginning.
