Description
 
Cisco Security has detected significant activity related to spam e-mail messages that claim to contain a package delivery failure notification for the recipient. The text in the e-mail message attempts to convince the recipient to follow a link to reschedule or to check on the status of the delivery. However, the link directs the user to a .zip file containing a malicious .scr file that, when executed, attempts to infect the system with malicious code.

E-mail messages that are related to this threat (RuleID4818, RuleID4821, and RuleID4818KVR) may contain the following files:

pdf_RW273018395CA.zip

pdf_trkRW184018395CA.zip
pdf_trkRW184018395CA.scr
pdf_RW273018395CA.zip
pdf_trk_invoice.scr

The pdf_RW273018395CA.scr file in the pdf_RW273018395CA.zip archive has a file size of 328,704 bytes. The MD5 checksum, which is a unique identifier of the executable, is the following string: 0x7B0291C64C98752F2E5095952FB5F7F3

The pdf_trkRW184018395CA.scr file in the pdf_trkRW184018395CA.zip attachment has a file size of 188,416 bytes. The MD5 checksum is the following string: 0x17F79ADB21B0CEC082466EF5C08D38DA
