On online trading platforms, fraudsters' methods of designing phishing traps are diverse and constantly evolving. The following are common strategies and their technical details, as well as corresponding prevention recommendations.： --- ###**1. Common design techniques for fishing traps** 1. **Fake websites and links** -**Technique**: Clone regular platform pages (such as payment pages, login interfaces), and pass similar domain names (such as`taobao.com 'Change to`taobao0.com `) or HTTPS camouflage (using a free SSL certificate) to enhance credibility. -**Technical implementation**: Use automated tools (such as Phishing Frenzy) to quickly generate phishing pages, and through short link services (如Bit.ly ) Hide the real URL. 2. **Dissemination of fishing information** -**Channels**: Send text messages, emails, and private social media messages with malicious links, falsely claiming that “the order is abnormal”“ "the account is frozen” or “low-price promotion”. -**Psychological induction**: Create a sense of urgency (such as “deal with other titles within 24 hours”), or use “Get it for free” and “High rebates” to trick you into clicking. 3. **False transactions and payment hijacking** -**Scenario**: Publish low-priced goods (such as half-price electronic products) on second-hand platforms, induce users to leave the supervision of the platform, and commit fraud through false payment links (such as forged Alipay pages) or direct transfers (such as WeChat scan code payment). -**Advanced technique**: Tamper with the payment interface, transfer user funds to an intermediate account and then transfer them in batches. 4. **Malware implantation** -*****: Induce the download of poisonous files through the names of “Order details”, “Logistics information”, etc. (such as`. exe`or`. apk`), or use Web page vulnerabilities (such as cross-site script attacks) to implant keyloggers. -**Target data**: Steal the password, bank card information saved by the browser, and even hijack the private key of the cryptocurrency wallet. 5. **Social engineering attacks** -**Disguise your identity**: Impersonate the platform's customer service (such as forging a work permit, official phone number), and request an SMS verification code and bank card number on the grounds of “refund” and “account upgrade”. -**Information paving**: Obtain users' personal information through public channels (such as social media) to enhance the credibility of speech. 6. **QR code fishing** -**Implementation method**: Embed a malicious QR code in the product description or chat, and the user will automatically jump to the phishing page or trigger a payment (such as WeChat password-free payment) after scanning the code. -**Concealment**: Use the characteristics of QR codes that are difficult to identify with the naked eye to avoid traditional link detection. --- ###**2. Technical details and tools** -**Domain name spoofing**: Attacks using IDN homomorphisms (such as `apple.com 'Replace with Cyrillic letters`аpple.com `) or confusion with subdomains (such as 'paypal.com.security-check.site`). -**Man-in-the-middle attack (MITM)**: Intercept communication between users and the platform in a public Wi-Fi environment and tamper with the content of the payment page. -**Automated tools**: Use open source frameworks such as GoPhish to send phishing emails in bulk, and combine AI to generate personalized tactics (such as imitating user purchase history). --- ###**3. User prevention strategy** 1. **Verify link and domain name** -**Check the URL**: Manually enter the official website address to avoid directly clicking on the SMS/email link; pay attention to the spelling of the domain name and the top-level domain name (such as the difference between `.com` and `.net`). -**SSL certificate check**: Click the lock icon in the browser address bar to confirm the certificate authority and validity period. 2. **Be wary of leaving the platform** -**Refuse external payments**: Insist on using the platform's built-in chat tools and payment system to avoid private transactions on WeChat and QQ. -**Verify the identity of customer service**: Contact through the customer service entrance embedded in the official App, and refuse to operate the account through unfamiliar phone calls or TEXT messages. 3. **Strengthen account security** -**Enable multi-factor authentication (MFA)**: Such as Google Authenticator (TOTP) or hardware key (YubiKey), avoid relying on SMS verification code. -**Monitor your account regularly**: Set transaction reminders to check whether there are abnormal small test transfers in bank turnover. 4. **Technical protective measures** -**Use anti-phishing plug-ins**: Install Netcraft Extension or HTTPS Everywhere to block known phishing websites. -**Update system and software**: Patch browser vulnerabilities to avoid malicious code using zero-day attacks. 5. **Raise safety awareness** -**Identify phishing characteristics**: such as grammatical errors in emails, vague LOGOS, and non-personalized names (such as “Dear customer”). -**Simulated attack test**: Improve recognition capabilities through phishing drills provided by the company (such as KnowBe4). --- ###**4. Platform and regulatory response** -**Risk monitoring**: Deploy a machine learning model to analyze abnormal transaction patterns (such as newly registered sellers initiating a large number of low-price transactions in a short period of time). -**User education**: Embed risk warning pop-ups in the payment link (such as “External link detected, beware of fraud”). -**Blockchain traceability**: Explore the use of Blockchain technology to record transaction links and track the flow of funds. --- Through the comparison of the above multi-level attack techniques and defense strategies, users can
