Social Engineering is the act of deceiving you into revealing confidential information or giving up control of your computer system.
Forms of Social Engineering
- Phishing attacks use email or malicious websites to solicit personal information by posing as a trustworthy organization such as financial institution or credit card company. Attackers often take advantage of current events and certain times of the year.
- Vishing leverages voice communication. This technique can be combined with other forms of social engineering that entice a victim to call a certain number and divulge sensitive information. Scammers can spoof caller ID and make it appear as though the bank is calling you. If you ever receive a call like this, hang up and call your local branch.
- Smishing exploits SMS, or text messages. Text messages can contain links to such things as webpages, email addresses or phone numbers that when clicked may automatically open a browser window or email message or dial a number.
Common indicators of phishing attempts
- Suspicious sender’s address. The sender's address may imitate a legitimate business. Cybercriminals often use an email address that closely resembles one from a reputable company by altering or omitting a few characters.
- Generic greetings and signature. Both a generic greeting—such as “Dear Valued Customer” or “Sir/Ma’am”—and a lack of contact information in the signature block are strong indicators of a phishing email. A trusted organization will normally address you by name and provide their contact information.
- Spoofed hyperlinks and websites. If you hover your cursor over any links in the body of the email, and the links do not match the text that appears when hovering over them, the link may be spoofed. 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). Additionally, cybercriminals may use a URL shortening service to hide the true destination of the link.
- Spelling and layout. Poor grammar and sentence structure, misspellings, and inconsistent formatting are other indicators of a possible phishing attempt. Reputable institutions have dedicated personnel that produce, verify, and proofread customer correspondence.
- Suspicious attachments. An unsolicited email requesting a user download and open an attachment is a common delivery mechanism for malware. A cybercriminal may use a false sense of urgency or importance to help persuade a user to download or open an attachment without examining it first.
