Continuing with the never ending series of malware downloaders is an email with the subject of Scan from a Samsung MFP coming or pretending to come from random companies, names and email addresses with a semi-random named zip attachment in the format of Untitled_date_random numbers.zip which delivers Locky ransomware. These actually started to come in last night after I went to bed and continued steadily during the night. The first was seen at about 11pm UTC<\/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
This is another one of the files that unless you have \u201cshow known file extensions enabled\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
8 December 2021 :Untitled_07122021_46160.zip: Extracts to: N396390423.jse Current Virus total detections: MALWR shows a download of an encrypted file from http:\/\/raivel.pt\/45gdfgf?SEOtErERwE=yLVujYkT which is converted by the script to XtPmJmcsvIP1.dll ( VirusTotal) Payload Security Locky has recently started to use non standard file extensions on the binaries. Sometimes they are numbers like 342, 343, 552 or sometimes tdb or .zk. All of these are actually DLL files that rundll32.exe will run via the macro or VBS \/ JS \/WSF scripting file telling it what to do.<\/p>\n
