Yet another Lokibot campaign. This time coming via a Fake DHL delivery failed email.
We frequently see comments saying ” how can anybody fall for this sort of scam”. Well it is extremely easy! It only needs a combination of very plausible circumstances to make you think it is genuine.
- First, you see the from DHL line in the email.
- Next the criminal Scammers are experts in Social Engineering & manipulation. The email wording is generic enough to apply to anybody, but personalised just enough, with key words and phrases that make you believe it is true. Many of us do receive numerous parcels from online shopping. We have all had problems with parcel deliveries from all delivery companies, where they can’t find our address. Several times I have received texts or phone calls from the delivery driver saying he can’t find my address. Frequently it has turned out he is in the wrong road and trying to deliver about 300 yards away where the road changes name on a bend. We all also get genuine emails later in the day saying we couldn’t deliver because we couldn’t get any reply from you, even though we were sitting waiting and we know the driver never even bothered to go into the road, let alone attempt to deliver the package.
I also recently received a phone call from a driver for a parcel I was expecting. He said that whoever had entered the details on his electronic system had only put my name, the road, postcode and phone number, not the house number. It turned out that the company sending me the parcel had forgotten to put the house number on the docket and on the parcel.
I am sure that if he had texted or emailed me instead, I might have clicked on a link or opened an attachment if I wasn’t so aware & deal with these sorts of scams and malware delivery methods daily.
- Unless you have “show known file extensions enabled“, can easily be mistaken for a genuine DOC or other common file instead of the .EXE file it really is, so making it much more likely for you to accidentally open it and be infected. This campaign uses an ISO file attachment that all versions of windows will automatically extract when double clicked. Look at these 2 screenshots that show the difference when you don’t have show file extensions enabled and when you do. You can clearly see without the .exe or .iso name showing, you can be easily persuaded that it is a message not a program that runs when you click it. A lot of people wouldn’t even know what an iso file is & just click regardless.
You can now submit suspicious sites, emails and files via our Submissions system
Remember many email clients, especially on a mobile phone or tablet, only show the Name in the From: and not the bit in <domain.com >. That is why these scams and phishes work so well. The Only big warning alert that anybody probably should have noticed is the date & time on the email. ( it actually arrived at 22.09 UTC Friday 8th February 2019. I doubt if anybody anywhere in Europe including the UK would pay much, if any attention to the Belgium DHL phone number and address. We have all got so used to so many companies using different European locations, especially with all the changes, problems and warnings about companies moving that Brexit is bringing to the UK

Now the other weird or strange thing that is happening with this & several other campaigns I have seen recently is the email content that gets delivered or displayed to a Microsoft Outlook user in msg format is different to the content I see on the mail server or when it is received by a different email client in .eml format. Also in .eml format the DHL image at the bottom of the email is an attachment not showing as part of the message
Outlook just skips over & totally ignores the initial part of a multi- part message. This is showing part of a different scam, fraud or malware campaign.
This is a multi-part message in MIME format. ------=_NextPart_000_0012_17B8C35E.ADAEE860 Content-Type: multipart/related; boundary="----=_NextPart_001_0013_17B8C35E.ADAEE860" ------=_NextPart_001_0013_17B8C35E.ADAEE860 Content-Type: multipart/alternative; boundary="----=_NextPart_002_0014_17B8C35E.ADAEE860" ------=_NextPart_002_0014_17B8C35E.ADAEE860 Content-Type: text/plain; charset="utf-8" Content-Transfer-Encoding: quoted-printable Good Day, Please be advised that your customer instructed us to transfer=20 the balance payment to your account and e mail you the swift=20 copy.

]All these malicious emails are either designed to steal your Passwords, Bank, PayPal or other financial details along with your email or FTP ( web space) log in credentials. Or they are Ransomware versions that encrypt your files and demand large sums of money to recover the files.All the alleged senders, amounts, reference numbers, Bank codes, companies, names of employees, employee positions, email addresses and phone numbers mentioned in the emails are all random. Some of these companies will exist and some won’t. Don’t try to respond by phone or email, all you will do is end up with an innocent person or company who have had their details spoofed and picked at random from a long list that the bad guys have previously found.
The bad guys choose companies, Government departments and organisations with subjects that are designed to entice you or alarm you into blindly opening the attachment or clicking the link in the email to see what is happening.
There are frequently dozens or even hundreds of different download locations, sometimes delivering the exactly same malware from all locations and sometimes slightly different malware versions from each one. Dridex, Locky and many other malwares do update at frequent intervals during the day, sometimes as quickly as every hour, so you might get a different version of these nasty Ransomware or Banking password stealer Trojans to the version we list here.
Be very careful with email attachments. All of these emails use Social engineering tricks to persuade you to open the attachments that come with the email. Whether it is a message saying “look at this picture of me I took last night” and it appears to come from a friend or is more targeted at somebody who regularly is likely to receive PDF attachments or Word .doc attachments or any other common file that you use every day.
The basic rule is NEVER open any attachment to an email, unless you are expecting it. Now that is very easy to say but quite hard to put into practice, because we all get emails with files attached to them. Our friends and family love to send us pictures of them doing silly things, or even cute pictures of the children or pets.
Never just blindly click on the file in your email program. Always save the file to your downloads folder, so you can check it first. Many malicious files that are attached to emails will have a faked extension. That is the 3 letters at the end of the file name. Unfortunately windows by default hides the file extensions so you need to Set your folder options to “show known file types. Then when you unzip the zip file that is supposed to contain the pictures of “Sally’s dog catching a ball” or a report in word document format that work has supposedly sent you to finish working on at the weekend, or an invoice or order confirmation from some company, you can easily see if it is a picture or document & not a malicious program.
If you see .JS or .EXE or .COM or .PIF or .SCR or .HTA .vbs, .wsf , .jse .jar at the end of the file name DO NOT click on it or try to open it, it will infect you.
While the malicious program is inside the zip file, it cannot harm you or automatically run. When it is just sitting unzipped in your downloads folder it won’t infect you, provided you don’t click it to run it. Just delete the zip and any extracted file and everything will be OK. You can always run a scan with your antivirus to be sure. There are some zip files that can be configured by the bad guys to automatically run the malware file when you double click the zip to extract the file. If you right click any suspicious zip file received, and select extract here or extract to folder ( after saving the zip to a folder on the computer) that risk is virtually eliminated. Never attempt to open a zip directly from your email, that is a guaranteed way to get infected. The best way is to just delete the unexpected zip and not risk any infection.
