A rise in the infection rate of the Locky .OSIRIS ransomware virus has been reported by security researchers. The virus has begun to spread with the same massive spam e-mail campaigns that have documents with malicious macros within them. If the ones spreading Locky .OSIRIS ransomware are back on track, then infections are expected to rise even more.
The Infection Method of Locky Ransomware
For the infection, this new spam wave of Locky uses pre-set list of e-mail addresses which are not flagged as spam. These sender addresses send a receipt in the form of an Adobe .PDF file, that has a name similar to “P23123.pdf”. The topic of the e-mail uses the word “Reciept” in it, making it seem that it has been sent as a form of some payment that the user has not made. In addition to this, convincing statements may be made in the e-mail’s body to further get the user to open the infection file.
Whatever the case may be, once this .PDF document is opened, it contains a document with the .docm file extension inside, which can be opened via Microsoft Word. This document can only be opened via opening the .PDF file. As soon as the word file is opened, it displays a fake text, with the following content:
This Document is protected!
1 Open the document in Microsoft Office. Previewing offline is not available for protected documents.
2 If this document was downloaded from your email, please click “Enable editing” from the yellow bar above.
3 Once you have enable editing please click on “Enable content” on the yellow bar above.
As soon as the user clicks on the “Enable content” button, infection with .OSIRIS Locky becomes inevitable.
Similar to other Locky variants, the virus’s first action is to delete the shadow volume copies from the computer which is infected, by executing the vssadmin command:
→ vssadmin delete shadows /all /quiet
For connection this Locky .OSIRIS iteration uses the hosts 126.96.36.199 and 188.8.131.52 to which it connects and sends information.
