Digital Breadcrumbs

Social Engineering Attacks

• Malicious software (malware) is installed into a computer fixed or mobile − to collect personal information over time.

• Computers or mobile devices are hacked for personal data.

• Phishing – criminals use deceptive e-mails to get users to divulge personal information, includes luring them to fake bank and credit-cards

websites.

“Pharming”: using deceptive e-mail messages to redirect users from an authentic website to a fraudulent one, which replicates the original in appearance.

– “SMiShing”: sending text messages (“SMS”) to cell phone users that trick them into going to a website operated by the thieves. Messages typically say that unless users go to the website and cancel, they will be charged for services they never actually ordered.

– “Spear-phishing”: impersonating a company employee/employer via e- mail in order to steal colleagues’ passwords/usernames and gain access the company’s computer system. ID thieves misuse victims’ personal info.
