Description
Cisco Security Intelligence Operations has detected significant activity related to spam e-mail messages that claim to contain an unspecified message for the recipient. The text in the e-mail message attempts to convince the recipient to open the attachment and view the details. However, the .zip attachment contains a malicious .exe file that, when executed, attempts to infect the system with malicious code.
E-mail messages that are related to this threat (RuleID4947) may contain the following files:
KB00484414.zip KB00484414.exe
The KB00484414.exe file in the KB00484414.zip attachment has a file size of 217,088 bytes. The MD5 checksum, which is a unique identifier of the executable, is the following string: 0x1AB633CDF11E328C37729E3E319DA6B5
Cisco Security Intelligence Operations analysts examine real-world e-mail traffic data that is collected from over 100,000 contributing organizations worldwide. This data helps provide a range of information about and analysis of global e-mail security threats and trends. Cisco will continue to monitor this threat and automatically adapt systems to protect customers. This report will be updated if there are significant changes or if the risk to end users increases.
