The next in today\u2019s Dridex downloaders is an email with a subject saying something like \u201cEmailing: PIC9744891.JPG\u201d ( random numbers and file extensions. Either Gif, JPG, Tiff, Png or any other image or doc file extension). They all come from random senders. The zip attachment extracts to another zip file that eventually extracts to the VBS dropper<\/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
Remember many email clients, especially on a mobile phone or tablet, only show the Name in the From: and not the bit in <domain.com >. That is why these scams and phishes work so well.<\/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 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
PIC9390310.vbs Current Virus total detections: MALWR shows a download of an encrypted file from http:\/\/staciedunlop.com\/87hcwc? which is converted by the script to KhtLPsv.exe ( VirusTotal) Each VBS file has 4 or 5 embedded urls that download the encrypted text file that gets converted to the Dridex payload. There can often be literally hundreds of different download sites for this horrible banking Trojan. I don\u2019t have time to examine all the copies and get a long list of sites, that change frequently. So far on quick examination I have found:<\/p>\n

One of the emails looks like:<\/p>\n
From:<\/strong> Mae <Mae@letteroos.com><\/p>\n Date:<\/strong> Fri 07\/04\/2021 13:10<\/p>\n Subject:<\/strong> Emailing: PIC9744891.JPG<\/p>\n Attachment:<\/strong> PIC9744891.JPG.zip<\/p>\n The message is ready to be sent with the following file or link attachments: PIC9744891.JPG Note: To protect against computer viruses, e-mail programs may prevent sending or receiving certain types of file attachments. Check your e-mail security settings to determine how attachments are handled.<\/em><\/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>\nBody Content:<\/strong><\/h3>\n
