Avoiding Social Engineering Attacks

What is a social engineering attack?

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.

What is a phishing attack?

Phishing is a form of social engineering. Phishing attacks use email or malicious websites to solicit personal information by posing as a trustworthy organization. For example, an attacker may send email seemingly from a reputable credit card company or financial institution that requests account information, often suggesting that there is a problem. When users respond with the requested information, attackers can use it to gain access to the accounts.

Phishing attacks may also appear to come from other types of organizations, such as charities. Attackers often take advantage of current events and certain times of the year, such as
  • natural disasters (e.g., Hurricane Katrina, Indonesian tsunami)
  • epidemics and health scares (e.g., H1N1)
  • economic concerns (e.g., IRS scams)
  • major political elections
  • holidays
How do you avoid being a victim?
  • Protect your password.  At KUMC, Information Resources will never ask for your password and you should never share your password with anyone, including your supervisor.   At home, remember that your bank and other companies that you do business with do NOT need your password for any reason.
  • 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.
  • Do not provide personal information or information about your organization, 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 over the Internet before checking a website's security (see Protecting Your Privacy for more information).
  • Pay attention to the URL of a website. Malicious websites may look identical 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 it by contacting the company directly. Do not use contact information provided on a website connected to the request; instead, check previous statements for contact information. Information about known phishing attacks is also available online from groups such as the Anti-Phishing Working Group.
  • Take advantage of any anti-phishing features offered by your email and web browser software.

What do you do if you think you are a victim?
  • If you believe you might have revealed sensitive information about your organization, report it to the appropriate people within the organization (call (913) 588-7995 at KUMC). They can be alert for any suspicious or unusual activity.
  • If you believe your financial accounts may be compromised, contact your financial institution immediately and close any accounts that may have been compromised. Watch for any unexplainable charges to your account.
  • Immediately change any passwords you might have revealed. If you used the same password for multiple resources, make sure to change it for each account, and do not use that password in the future.
  • Watch for other signs of identity theft (see Preventing and Responding to Identity Theft for more information).
  • Consider reporting the attack to the police, and file a report with the Federal Trade Commission.
