Course Introduction：Phishing is an online fraud method that induces users to provide sensitive information by disguising as a trusted organization. 1. Phishing emails are common and realistic, and often induce clicking on links or downloading attachments on the grounds of abnormal account and order problems. When identifying, check the sender's email address, pay attention to spelling errors, and avoid clicking on links directly; 2. Fake websites are the core phishing tools, and the page design is similar to formal websites but the URL is different. Prevention methods include checking the URL, using browser security functions, and enabling two-factor verification; 3. Social media and SMS are also phishing channels. Common methods include pretending to be customer service, false lottery, express delivery abnormalities, etc. Coping skills include being vigilant to actively contact customer service, not trusting high-reward information, and verifying the source of information through official channels.
