We are seeing a quite active malspam campaign distributing Lokibot hitting UK at the moment. They are using multiple spoofed email sending addresses, loads of different subject lines and body contents. All the attachments have different names as well.
A few examples of senders are:
- Frank <firstname.lastname@example.org>
- ???????????? <email@example.com>
Some subjects are:
- COPIES INV. 773
- OUR ORDER NO. 157/17 DATED 3/5/18 118642
- Re:Revised quotation
- Purchase offer
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.
Attachment names include: ( all have identical content by file #)
- PURCHASE ORDER NO. 10019 DATED 3.5.2018_118642,pdf.z
- COPIES INV. 773.pdf.z
- Revised quotation.pdf.z
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 £350/$400) 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.
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.
