What is Social Engineering?
Instead of attacking a computer, social engineering is the act of interacting and manipulating people to obtain important and/or sensitive information or to perform an act that is latently harmful. Basically, it is hacking a person instead of a computer. A social engineer can use the phone, the internet, or even show up in person to perform the malicious act. They can be after information such as ID numbers, usernames, passwords, server names, machine names, remote connection settings, schedules, credit card numbers, etc. They may also try to get someone to install some malicious software, visit an unscrupulous website, or even access unauthorized locations.
What can I do?
Be educated, aware, and a little bit paranoid.
Never give out:
- Usernames – Administrators should know them or can find out themselves
- Passwords – Administrators can ask you to enter them into the computer, but do not tell anyone.
- ID numbers
- PIN numbers
- Server names
- System information
- Credit card numbers
- Sensitive Data
Be aware of what is being asked:
- Via the phone:
- Ask for the full and correct spelling of their name, a call back number, and the reason they need the information.
- Have them contact the source directly if asked for information managed by someone else.
- When in doubt, put the caller on hold or tell them you will call them back. This gives you time to log any strange calls and verify if it is okay to give out information.
- Via the internet:
- Watch for any suspicious attachments that someone wants you to download in an e-mail.
- Avoid any links in e-mails that request you enter account information for verification (this is known as phishing).
- Administrators will never tell you or ask for passwords over e-mail.
- E-mails from SEASnet will be in plain text without attachments, unless you requested the attachment.
- SEASnet may give you password guidelines, but we will never tell you to change it to something specific like “abcde”
- When in doubt, you can also contact the e-mail sender in a phone call or new e-mail and ask if their e-mail with the subject of <copy the subject> was valid.
- In person:
- Never be pressured to comply when someone says “Do you know who I am?”
- Ask a contact to verify the person’s need for information.
- Have someone asking for configuration/access questions to contact the source directly.
- Someone from SEASnet should only ask you to enter your username/password on the computer, not have you write it down or verbally say it.
- Always be aware of people around you when entering your username/password.
- When in doubt, contact SEASnet or your supervisor.
- Shred and secure any documents that someone can obtain by looking through your trash.
IMPORTANT: When in doubt, ask the person to wait while you verify (a) their identity, (b) the need to know, and (c) if you are the rightful/authorized source of the information.
