Digital Breadcrumbs
Social Engineering A7acks
• Malicious sovware (malware) is installed into a computer fixed or mobile − to collect personal informa`on over `me.
• Computers or mobile devices are hacked for personal data.
• Phishing – criminals use decep`ve e-‐mails to get users to divulge personal informa`on, includes luring them to fake bank and credit-‐
cards websites.
“Pharming”: using decep`ve e-‐mail messages to redirect users from an authen`c 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”: impersona`ng 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 vic`ms’ personal info.
