The next in the never ending series of malware downloaders is an email with the subject of efax message from unknown \u2013 2 page(s) pretending to come from eFax <message@inbound-efax-au.org> with a link to download a zip file that extracts to 2 identical .js files named fax page 1 and fax page 2<\/p>\n

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 \u00a3350\/$400) 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.

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 Please read our How to protect yourselves page<\/a> for simple, sensible advice on how to avoid being infected by this sort of socially engineered malware.<\/p>\n 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.<\/p>\n This is another one of the files that unless you have \u201cshow known file extensions enabled<\/a>\u201c, 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.<\/p>\nBody Content<\/strong>:<\/h3>\n
