In a social engineering attack, an attacker uses human interaction (social skills) to obtain or compromise information about an organization or its computer systems. An attacker may seem unassuming and respectable, possibly claiming to be a new employee, repair person, or researcher and even offering credentials to support that identity. However, by asking questions, he or she may be able to piece together enough information to infiltrate an organization's network. If an attacker is not able to gather enough information from one source, he or she may contact another source within the same organization and rely on the information from the first source to add to his or her credibility.
How do you avoid being a victim?
Be suspicious of unsolicited phone calls,visits, or email messages from individuals asking about employees or other internal information. If an unknown individual claims to be from a legitimate organization, try to verify his or her identity directly with the company.
Do not provide personal information or information about yourorganization, including its structure or networks, unless you are certain of a person's authority to have the information.
Do not reveal personal or financial information in email,and do not respond to email solicitations for this information. This includes following links sent in email.
Don't send sensitive information overthe Internet before checking a website's security.
Pay attention to the URL of a website. Malicious websites may lookidentical to a legitimate site, but the URL may use a variation in spelling or a different domain (e.g., .com vs. .net).
If you are unsure whether an email request is legitimate, try to verify itby contacting the company directly. Do not use contact information provided on a website connected to the request; instead, check previousstatements for contact information. Information about known phishing attacks is alsoavailable online from groups such as the Anti-Phishing Working Group.
Take advantage of any anti-phishing features offeredby your email client and web browser.
