Description
 
Cisco Security Intelligence Operations has detected significant activity related to Portuguese-language spam e-mail messages that claim to contain personal pictures for the recipient. The text in the e-mail message attempts to convince the recipient to follow a link and view the pictures.

E-mail messages that are related to this threat (RuleID4856, and RuleID4867KVR) may contain the following file:
Cancelamento.cpl
The Cancelamento.cpl has a file size of 597,504 bytes. The MD5 checksum, which is a unique identifier of the executable, is the following string: 0x9D8CDDE2BDCFE8EEBD1348D8E0935CCB

A variant of the Cancelamento.cpl has a file size of 372,736 bytes. The MD5 checksum is the following string: 0xB49027B2E0B664063E6BB38FAC7D44CD

A third variant of the Cancelamento.cpl has a file size of 475,136 bytes. The MD5 checksum is the following string: 0x0AB6F76A83154DF73DA86B4DC715040A

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.

Cisco security appliances 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 Web Security Appliances will not be impacted by these attacks.  Cisco security appliances are automatically updated to prevent both spam e-mail and hostile web URLs from being passed to the end user.
