Next in today\u2019s Trickbot banking Trojans coming via the Necurs botnet is an email with the subject of Voice Message Attached from 01258895166 \u2013 name unavailable [ random numbered] pretending to come from vm@unlimitedhorizon.co.uk with a zip attachment which downloads<\/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
unlimitedhorizon.co.uk has not been hacked or had their email or other servers compromised. They are not sending the emails to you. They are just innocent victims in exactly the same way as every recipient of these emails<\/p>\n

However Payload Security couldn\u2019t get anything<\/p>\n The sites I can see in this js file are: aprendersalsa.com\/nhg67r? \u2013 artegraf.org\/nhg67r? \u2013 asheardontheradiogreens.com\/nhg67r?-asuntomaailma.com\/nhg67r?<\/p>\n Attached is a zip of all the zips I have received, Hopefully one of the other researchers can get a working payload. It will probably be similar to an earlier Trickbot version today that I didn\u2019t report on. trickbot_21_july_wsf<\/p>\n One of the emails looks like:<\/p>\n From<\/strong>: vm@unlimitedhorizon.co.uk<\/p>\n Date:<\/strong> Fri 21\/07\/2017 13:49<\/p>\n Subject:<\/strong> Voice Message Attached from 01258895166 \u2013 name unavailable<\/p>\n Attachment:<\/strong> 01258895166_6382218_592164.zip<\/p>\n Body content:<\/strong><\/p>\n Time: 21-Jul-2017 10:15:23<\/em><\/p>\n Click attachment to listen to Voice Message<\/em><\/p>\n <\/p>\n These malicious attachments 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 \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. 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 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>\nScreenshot<\/h3>\n
