A very simple email and attachment that shouldn’t infect anybody. The malware bad actors have made a total mess-up of this one and given the malware attachment a file extension that windows does not know what to do with. They added a file called Contract Details,pdf.r00 which actually is a rar file with a renamed extension. Simply renaming it to .rar will give a working .rar file that extracts to a .exe file. I really don’t know what malware this is. It has a digital certificate that is untrusted and invalid
Update: Thanks to malwarehunterteam, I am informed it is an ISR stealer
Anyway this latest in the series of malware downloaders is an email with the subject of PURCHASE CONTRACT that I assume is coming or pretending to come from random companies, names and email addresses ( I have only received 1 copy of this so far)
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.
One of the emails looks like:

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.
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.
