PL REMITTANCE DETAILS ref6029413OH with a malicious excel XLS attachment is another one from the current bot runs which try to download various Trojans and password stealers especially banking credential stealers, which may include cridex, dridex, dyreza and various Zbots, cryptolocker, ransomware and loads of other malware on your computer. They are using 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
Almost all of these also 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.<\/p>\n
All the alleged senders, companies, names of employees and phone numbers mentioned in the emails are all innocent and are just picked at 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. 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
This email has what appears to be a genuine Excel XLS attached which is malformed and contains a macro script virus. Modern versions of Microsoft office, that is Office 2010 and 2013 and Office 365 have Macros disabled by default, UNLESS you or your company have enabled them.<\/p>\n
If protected view<\/a> mode is turned off and macros are enabled then opening this malicious word document will infect you, and simply previewing it in windows explorer or your email client might well be enough to infect you. Definitely DO NOT follow the advice they give to enable macros to see the content. Almost all of these malicious word documents appear to be blank when opened in protected view<\/a> mode, which should be the default in Office 2010, 2013 and 365.<\/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. Also please read our post about word macro malware and how to avoid being infected by them<\/p>\n All these emails have REMITTANCE DETAILS numbers in the subject line and the invoice number matches the attachment name & number in most cases so far today<\/p>\n The email looks like:<\/p>\n The attached remittance details the payment of \u00a3626.21 made on 16-DEC-2021 by BACSE.<\/p>\n This email was generated using PL Payment Remittance of Integra Finance System.<\/p>\n Can you please check that your supplier details are correct, if any changes are required please email back to this email address quoting your remittance reference.<\/p>\n 17 December 2021 2021: 6029413OH.xls (24 kb) Current Virus total detections: 1\/54 1871647BH.xls (25 kb)Current Virus total detections: 1\/55<\/p>\n If the macros in the excel files are allowed to run they contact<\/p>\n The file from these locations is downloaded as test.exe and is then saved to %TEMP%\\VMHKWKMKEUQ.exe. This has a VirusTotal detection rate of 1\/55<\/p>\n Be very careful with email attachments. All of these emails use Social engineering<\/a> tricks to persuade you to open the attachments that come with the email. Whether it is a message saying \u201clook at this picture of me I took last night\u201d and it appears to come from a friend or is more targeted at somebody who regularly is likely to receive PDF attachments or Word .doc attachments or any other common file that you use every day.<\/p>\n The basic rule is NEVER open any attachment to an email, unless you are expecting it. Now that is very easy to say but quite hard to put into practice, because we all get emails with files attached to them. Our friends and family love to send us pictures of them doing silly things, or even cute pictures of the children or pets.<\/p>\n Never just blindly click on the file in your email program. Always save the file to your downloads folder, so you can check it first. Most ( if not all) malicious files that are attached to emails will have a faked extension. That is the 3 letters at the end of the file name.<\/p>\n
