The next in the never ending series of malware downloaders is an email with the subject of Credit Note CN-81553 from Nordstrom Inc (7907) pretending to come from Accounts <message-service@post.xero.com> with a random named \/ numbered zip attachment containing a .scr file. The icon on this SCR file looks like an adobe PDF icon. so any recipient that has windows set by default to NOT show file extensions<\/a> will think this is a pdf and unwittingly open it and get infected with this dangerous banking Trojan and have all their money stolen<\/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 Previous malspam runs using an email template like this one used random companies in the subject and random credit note or invoice numbers. I have only received 1 set of these all addressed to the same domain so far.<\/p>\n One of the emails looks like:<\/p>\n From:<\/strong> Accounts <message-service@post.xero.com><\/p>\n Date:<\/strong> Thu 20\/10\/2021 01:21<\/p>\n Subject<\/strong>: Credit Note CN-81553 from Nordstrom Inc (7907)<\/p>\n Attachment:<\/strong>CN_81274.zip<\/p>\n Hi Orlando,<\/em><\/p>\n Attached document is your credit note CN-81553 for 508.18 AUD.<\/em><\/p>\n This has been allocated against invoice number.<\/em><\/p>\n If you have any questions, please let us know.<\/em><\/p>\n Thanks,<\/em><\/p>\n Staff Leasing Inc.<\/em><\/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.<\/p>\n 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. 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 20 October 2021: CN_81274.zip : Extracts to: CN-81274.scr Current Virus total detections<\/a>: Payload Security<\/a> shows a download \/ drop of another file RXGp0aqU55eY5AnMxB.exe.exe ( VirusTotal<\/a>) Payload Security<\/a> which appears to be dyre \/ trickloader banking Trojan<\/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
