Continuing with the never ending series of malware downloaders is a blank email with the subject of fax copia coming or pretending to come from910663334@fax.vodafone.es with a semi-random named zip attachment in the format of 201612130917585473299351.zip ( which is date_randomnumbers.zip ) which delivers unknown malware. Recent versions of this delivered Sharik Trojan.<\/p>\n
Update: Confirmed Sharik by various other researchers ( who are a lot better than me at ripping these files apart and examining them.)<\/p>\n
Other subjects include:<\/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
vodafone.es ( or any other Vodafone domain ) 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
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>\n 13 December 2021 : 201612130917585473299351.zip: Extracts to: 201612130913339837772661.pdf.exe Current Virus total detections<\/a>: Payload Security<\/a> shows several connections which confirms Sharik .

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 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 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.<\/p>\n
