Cisco Security Intelligence Operations has detected significant activity on June 23, 2012.
Cisco Security Intelligence Operations has detected significant activity related to spam e-mail messages that claim to contain a bill of sale for the recipient. The text in the e-mail message leads the user to believe that the message originates from a trusted source and that the included attachment includes information relevant to a business operation. However, the 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 (RuleID4278) may contain the following file: ttcopy.exe
The ttcopy.exe file in the attachment has a file size of 374,731 bytes. The MD5 checksum is the following string: 0x01E5C46A34253A2D219D04596E540D52
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 IronPort systems to protect customers. This report will be updated if there are significant changes or if the risk to end users increases.
Cisco IronPort Virus Outbreak Filters protect customers during the critical period between the first exploit of a virus outbreak and the release of vendor antivirus signatures. E-mail that is managed by Cisco and end users who are protected by Cisco IronPort web security appliances will not be impacted by these attacks. Cisco IronPort appliances are automatically updated to prevent both spam e-mail and hostile web URLs from being passed to the end user.
