Continuing with the never ending series of malware downloaders is an email with the subject of IRS Urgent Notification coming or pretending to come from Dick Richardson who pretends to be an IRS Tax Officer. I have seen dozens of these and they all come from random email addresses. Dick Richardson changes his job in different emails. Sometimes he is a tax officer or a Tax Specialist or Tax department manager as well as an official representative<\/p>\n
These must obviously be aimed at US recipients because The UK does not have an IRS service, we have HMRC. But after following the link and downloading the zip file, you are redirected to the UK gov.uk home page. Anyway, this looks like some sort of ransomware from the virustotal reports, but I am not 100% sure which one.<\/p>\n
Update: I am reliably informed this is Shade\/ Troldesh ransomware<\/p>\n
Other subjects include:<\/p>\n
<\/p>\n
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.<\/p>\n
This is another one of the files that unless you have \u201cshow known file extensions enabled\u201c, can easily be mistaken for a genuine DOC \/ PDF \/ JPG or other common files instead of the .EXE \/ .JS file it really is, so making it much more likely for you to accidentally open it and be infected.<\/p>\n

One of the emails looks like:<\/p>\n

Some include:<\/p>\n <\/p>\n So far I am seeing very few duplicated download sites. I have received almost 250 copies of this, so there are a lot of compromised sites being used in this malspam run delivering ransomware<\/p>\n 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.<\/p>\n 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\u2019t. Don\u2019t 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.<\/p>\n 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.<\/p>\n\n
