A very strange one that I cannot work out if it is a phishing attempt, an attempt to deliver malware or just a cock-up by the bad guys sending it.
An email in a mixture of Spanish & German language that looks like some sort of Mexican tax invoice with the subject of Асυѕе ԁе Сіtа / Асlаrасіօոеѕ 2016. coming from SAT <email@example.com> with a link in the email body that goes to http://xander.mx/media/fotos/_notes/registro-sat.php which redirects to https://account.live.com/Consent/Update?ru=https://login.live.com/oauth20_authorize.srf%3flc%3d2057%26client_id%3d000000004019B008%26scope%3dwl.signin%2520wl.basic%2520wl.emails%2520wl.contacts_emails%26response_type%3dcode%26redirect_uri%3dhttp://satservicios2.ddns.net/oauth-hotmail.php%26mkt%3dEN-GB%26scft%3dDZCFqShXT9jWJ3kHPr5es4u6bS29Hyx1U9LgI8UJNcz*6oV193zAOt1BpXN9Z92rbrMRWpqJ95EL7lEw7KoZi7s5Pq9pqGiNw!3Te*EnLyc7NNeoDNFqxN8!TlvaOmsd8y1hmztvJRtMhesWqCw3cznO!LllCqzxtuWvDhYACCew%26contextid%3d37A404BC683B3C80&mkt=EN-GB&uiflavor=web&id=279469&client_id=000000004019B008&rd=satservicios2.ddns.net&scope=wl.signin+wl.basic+wl.emails+wl.contacts_emails&cscope= which asks for lots of access and permissions to use your Microsoft account.
It is an app on satservicios2.ddns.net that asks for the Microsoft account access. My gut feeling is that this is a malware delivery attempt using this dynamic IP address service that the bad guys are using to hide the actual IP address of the malware or control server. However I have no idea why it is asking for my Microsoft account details. I am guessing and I stress that this is a guess, that the malware gangs are trying to regain control of the necurs botnet that has been down for several weeks or set up a new botnet using Microsoft accounts as the authorisation method.
Obviously I don’t have a spare throwaway Microsoft account to play with & see what happens if I did enter any details. I do not intend to create one, just for this. So I have not got any further.
They use email addresses and subjects that will entice a user to read the email and open the attachment. A very high proportion are being targeted at small and medium size businesses, with the hope of getting a better response than they do from consumers.
One of the emails looks like:

This email is actually coming from the German company brands-fahrzeugtechnik.de, who must have either had had their email server compromised or an authorised user has had his log in details used.
The malware in these malicious attachments or at the end of the link in the email normally have a password stealing component, with the aim of stealing your bank, PayPal or other financial details along with your email or FTP ( web space) log in credentials. Many of them are also designed to specifically steal your Facebook and other social network log in details. A very high proportion are Ransomware versions that encrypt your files and demand money ( about £350/$400) 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.
Please read our How to protect yourselves page for simple, sensible advice on how to avoid being infected by this sort of socially engineered malware.
Previous campaigns over the last few weeks have delivered numerous different download sites and malware versions. There are frequently 5 or 6 and even up to 150 download locations on some days, sometimes delivering the exactly same malware from all locations and sometimes slightly different malware versions. Dridex /Locky does 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.
This is another one of the files that unless you have “show known file extensions enabled“, can easily be mistaken for a genuine DOC / PDF / JPG or other common file instead of the .EXE / .JS file it really is, so making it much more likely for you to accidentally open it and be infected.
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 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.
