Email, Spam & Undeliverable Messages

dtedesc1

The College’s mail servers receive approximately 4 million messages a month. of which, roughly 60% are spam. It’s quite clear why scanning inbound messages for spam and viruses is desirable. These message are stopped by our scanning service and are never delivered to our servers. That’s why you need to log in to an external service to take any further action on those messages. You can configure this scanning to always deliver, or whitelist, particular addresses or domains, ie, allow everything from vassar.edu. Plans are being made to implement outbound message scanning. The College’s servers don’t send out a huge … Continue reading Email, Spam & Undeliverable Messages

Happy Valentine’s Day?! Join a Botnet!!

Nick

Malware writers are hoping that you’ll open that Valentine’s Day card they sent you. Unfortunately, in addition to a greeting, the seemingly innocent “card” will be downloading malicious software to your PC. Once downloaded, your PC will become a bot, or drone, and will then join a “botnet“. The good news is that these trojan Valentine’s Day cards require you to click on a URL link within the email. That link will then show you festive images (below) while it downloads malicious software such as ‘valentine.exe’. The downloads are constantly changing (morphing) so as to avoid detection by anti-virus software. … Continue reading Happy Valentine’s Day?! Join a Botnet!!
