How do I spot Spam, Scams, & Viruses in my Inbox?

You can't always spot these email hoaxes. Spammers and phishers are getting better everyday at making messages that look authentic. Sometimes the bad grammar in the message or the reply to email address will give away the hoax but not always. If in doubt call the sender or the CTS Help Desk to determine the validity of the message.

The main rule of thumb is NEVER respond to any email with confidential information (username, password, social security number, etc.). No legitimate business will ever ask for this information via email.

Report Spam/Phishing/Virus emails to the CTS Help Desk immediately and look here to see if CTS is aware of the newest threat.

Causes

E-mail spam today is sent via networks of virus - or worm -infected personal computers in homes and offices around the globe; many modern worms install a backdoor which allows the spammer access to the computer and use it for malicious purposes. This complicates attempts to control the spread of spam, as in many cases the spam doesn't even originate from the spammer.

Once a computer or mail account has responded back to a phishing email with their username and password the account will be compromised and then it will act a spammer, sending or relaying thousands of email messages per day. (Information from Wikipedia.org).

This Spam obviously has a large impact on our network activity and mail performance.

Solutions

NEVER respond to any email with confidential information (username, password, social security number, etc.). No legitimate business will ever ask for this information via email.

Never click on links or attachments in email unless you are expecting them. If you get a eCard from someone, send them a message thanking them for the card and asking them to verify they sent you one. Call the sender to verify the message is legit if you are doubtful. We do scan attachments for viruses and remove them if found, but some files such as password protected files can get through on occasion and links are not affected by this scan.

Sending Mass Mailings

When University departments need to send emails to a large group of people, (more than 300) please notify the Help Desk during your planning phase. Large mass emails can obstruct the flow of normal email during peak use hours. Do not send a large email via Outlook. We use Lyris distribution lists or our Student Mass Mailer application for these purposes because these methods are automatically delayed until 8 p.m. to avoid this conflict.

People that intend on sending mass mailings should abide by the chart below to not cause unnecessary Spam during peak use hours:

Sending Method

Population / Sending Time
