The latest news making headlines around the world is about the partial shutdown of the US government, which failed to agree on a new budget. Ever quick to take advantage of a situation, cybercriminals have begun to send various spam messages related to the government shutdown. These spam messages have started flowing into the Symantec Probe Network. We have observed that most of the spam samples encourage users to take advantage of clearance sales on cars and trucks.
