An email with the subject of Unity Link New Server Update pretending to come from xm.nl@unitylink.com <abelen@unitylink.com> with a zip attachment which contains an executable file Updated Unityink Server..exe and an image, which drop\/create various Java.jar files. This is likely to be a Java Adwind or Java Jacksbot version, although VirusTotal analysis results seem a bit confused and only give generic detections<\/p>\n
We first saw this email template and similar attack using RAR files HERE<\/a> about 4 months ago. Whether it is Adwind or Jacksbot they are both nasty cross OS backdoor Trojans<\/p>\n WARNING:<\/strong> Java Adwind<\/a> is a very dangerous remote access backdoor Trojan, that has cross OS capabilities and can potentially run and infect any computer or operating system including windows, Apple Mac, Android and Linux. It however can only be active or infect you if you have Sun \/ Oracle Java installed. Along with most security professionals, I strongly urge you to uninstall java and not use it, unless you have a pressing need for it. The majority of domestic ( home ) users and small businesses have no need for Java on their computers. This Article<\/a> from a couple of years ago explains why you should remove it. If you cannot remove it then it must be kept up to date<\/a> and be extremely careful with what you download or open.<\/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 Unityink has not been hacked or had their email or other servers compromised. They are not sending the emails to you. They are just innocent victims in exactly the same way as every recipient of these emails<\/p>\n One of the emails looks like:<\/p>\n From:<\/strong> xm.nl@unitylink.com <abelen@unitylink.com><\/p>\n Date:<\/strong> Tue 30\/08\/2016 07:13<\/p>\n Subject:<\/strong> Unity Link New Server Update<\/p>\n Attachment:<\/strong> Unity Link New Server Update.zip<\/p>\n Dear Agent,<\/em><\/p>\n Find attach New update details with password, kindly sign and branch seal on the attach authorization for security updates.<\/em><\/p>\n Best regards,<\/em><\/p>\n ALAA ELDIN BEBARS<\/em> Unity Link services Ltd| P.O.

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 30 August 2016 : Unity Link New Server Update.zip : Extracts to: Updated Unityink Server..exe Current Virus total detections<\/a>: MALWR<\/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
