An email with the subject of Remittance coming from random email addresses, companies and names with a malicious word doc or Excel XLS spreadsheet attachment is another one from the current bot runs which try to download various Trojans and password stealers especially banking Trojans like Dridex or Dyreza and ransomware like Locky, crypto locker or Teslacrypt.<\/p>\n
They are using email addresses and subjects that will scare or entice a user to read the email and open the attachment. A very high proportion are being targeted at small and medium-sized businesses, with the hope of getting a better response than they do from consumers.<\/p>\n
The name of the alleged sender, in this case, Bridgette matches the name of the accountant in the body of the email<\/p>\n
The email looks like this:<\/p>\n
From:<\/strong> Bridgette \u2013 WITAN PACIFIC INVESTMENT TRUST <Cunningham.Bridgette3@leonduniec.com><\/p>\n Date<\/strong>: Fri 04\/03\/2021 10:30<\/p>\n Subject:<\/strong> Remittance<\/p>\n Attachment:<\/strong> rem.advice-3798605447.rtf<\/p>\n Body content:<\/strong><\/p>\n Dear Sir\/Madam,<\/p>\n Hope you are well. I am writing you to let you know that the full amount specified in the contract has been paid into your bank account on the 1st of March at 14 through the BACS payment system and should reach the destination (beneficiary\u2019s) account within 3 working days.<\/p>\n To see full payment details please refer to the remittance advice note attached to the letter.<\/p>\n Any queries? Please reply back with your questions and you will receive a prompt and qualitative response as soon as possible. Please do not hesitate to write to us.<\/p>\n Bridgette Cunningham You can now send any suspicious files for examination by the antivirus companies via our submission system<\/strong><\/p>\n 4 March 2021: rem.advice-3798605447.rtf<\/p>\n Current Virus total detections and MALWR is unable to detect any HTTP connection or download any malware, which is probably due to anti-analysis protection in the word doc RTF. It will almost certainly turn out to download Dridex banking trojan, Locky or another similar ransomware<\/p>\n Update: Dynamoo has posted some locations for the downloads which appear to be Dridex banking Trojan<\/p>\n Previous campaigns over the last few weeks have delivered 5 or 6 and quite often up to 10 or 12 different versions, some with word doc attachments and some with Excel Xls attachments. There are frequently 5 or 6 download locations all delivering slightly different malware versions. Dridex \/Locky does update at frequent intervals during the day, so you might get a different version of this nasty Ransomware or banking, password stealer Trojan.<\/p>\n All the alleged senders, companies, names of employees, phone numbers, amounts, reference numbers etc. 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 other 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 attachment contains what appears to be a genuine word doc or Excel XLS spreadsheet with either a macro script or an embedded OLE object that when run will infect you.<\/p>\n Modern versions of Microsoft office, that is Office 2010, 2013, 2016 and Office 365 should be automatically set to higher security to protect you.<\/p>\n By default protected view is enabled and macros are disabled UNLESS you or your company have enabled them. If protected view 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 or enable editing to see the content.<\/p>\n Most of these malicious word documents either appear to be totally blank or look something like these images when opened in protected view mode, which should be the default in Office 2010, 2013, 2016 and 365. Some versions pretend to have a digital RSA key and say you need to enable editing and Macros to see the content. Do NOT enable Macros or editing under any circumstances.<\/p>\n <\/p>\n At this time, these malicious macros only infect windows computers. They do not affect a Mac, iPhone, IPad, Blackberry, Windows phone or Android phone.<\/p>\n The malicious word or excel file can open on any device with an office program installed, and potentially the macro will run on Windows or Mac or any other device with Microsoft Office installed. BUT the downloaded malware that the macro tries to download is windows specific, so will not harm, install or infect any other computer except a windows computer. You will not be infected if you do not have macros enabled in Excel or Word. These Macros do not run in \u201cOffice Online\u201d Open Office, Libre Office, Word Perfect or any other office program that can read Word or Excel files.<\/p>\n
