We are seeing an uptick in the FedEx \u201d unable to deliver\u201d malspam emails this week. We see them daily and I don\u2019t normally bother to post about them, because they are so common and I always get 1 or 2 every day.. However today I am receiving quite an increase in numbers over the usual amount. I have only looked quickly at 1 of the attachments today. With the holiday season quite quickly approaching and many more people shopping online, we will see a dramatic increase in these over the next few weeks and months as more people wait for their deliveries.<\/p>\n
Update 9 November 2021:<\/strong> A change to these today with a word doc attachment delivering Locky ransomware<\/a>\u00a0rather than the more typical Nemucod ransomware versions<\/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 They all come from compromised email accounts and hacked servers. The name of the Sr. Support Agent or Sr. Operation Manager who pretends to send these emails is different in each example and fairly random, but that name in the body of the email will match the alleged sender . Quite a high proportion of these do get past spam filters because the compromise accounts used to send the emails have correct authentication for the sending server. They pass DKIM and SPF checks. They tend to keep the volume relatively low from each server, so warning alerts to server management do not occur and consequently spam filtering becomes harder.<\/p>\n The sort of subjects that you see with this malspam nemucod ransomware campaign which will always have random numbers include:<\/p>\n One of the emails looks like:<\/p>\n From:<\/strong> FedEx Ground <wade.barry@hosteriasanpatricio.com.ar> or FedEx 2Day A.M. <ruben.morris@hosteriasanpatricio.com.ar><\/p>\n Date:<\/strong> Thu 01\/09\/2021 19:22<\/p>\n Subject:<\/strong> Shipment delivery problem #0000613766 or Delivery Notification, ID 00898050<\/p>\n Attachment:<\/strong> FedEx_ID_0000613766.zip<\/p>\n Dear Customer,<\/em><\/p>\n We could not deliver your item.<\/em><\/p>\n Please, open email attachment to print shipment label.<\/em><\/p>\n Sincerely,<\/em><\/p>\n Wade Barry,<\/em><\/p>\n Sr. Support Agent.<\/em><\/p>\n Or<\/p>\n Dear Customer,<\/em><\/p>\n We could not deliver your item.<\/em><\/p>\n Shipment Label is attached to email.<\/em><\/p>\n Warm regards,<\/em><\/p>\n Ruben Morris,<\/em><\/p>\n Sr. Operation Manager.<\/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. 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 : FedEx_ID_0000613766.zip : Extracts to: FedEx_ID_0000613766.doc.wsf Current Virus total detections<\/a>: Payload Security<\/a> shows downloads of the usual multiple files from www.industrial-automation.at\/counter\/?ad=17MGS22ZVQcqSyHw4VU2NvC5SL4eCPhCJb&id=LZUB9RUv-KCRW63gDdZ5mD075Y_vJ1F6feiXr_Sv5Nbbhxr8QKIPLwoOhYdjCOIqaWV65TnMZepmeok-Renqlmw1ioeBLbM8&rnd=01 ( with a range from 01 \u2013 04 that delivers different parts of the malware package )<\/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>\n\n
