Why is WiFi not cracked? 10天热门话题与安全指南
Recently, network security issues have once again become the focus of heated discussions across the Internet. According to statistics from social media and technology forums within 10 days, WiFi security issues ranked among the top 5 hot topics, especially the search volume for keywords such as public WiFi vulnerabilities and home network protection surged. The following is a security protection guide combined with hotspots to help you avoid WiFi being cracked.
1. Hotspot data across the entire network: WiFi security attention analysis (last 10 days)
| Ranking | keywords | Search volume (10,000 times) | Related topics |
|---|---|---|---|
| 1 | Public WiFi Risks | 28.5 | Phishing hotspots, data leaks |
| 2 | WiFi password cracking | 19.3 | WPA2 vulnerability, brute force cracking |
| 3 | Router security settings | 15.7 | Default password, firmware updates |
| 4 | 5G WiFi security | 12.1 | Frequency band isolation, encryption protocol |
| 5 | Smart home intrusion | 8.9 | 物联网设备漏洞 |
2. WiFi core measures to prevent cracking
1. Strengthen encryption protocol
Avoid using old WEP encryption, preferWPA3(if supported by the device) orWPA2-AES. According to statistics, it takes several months to crack WPA3, but only a few minutes for WEP.
2. Modify default router settings
Hackers often use the default administrator account (such as admin/admin) to invade. suggestion:
3. Password policy upgrade
Weak passwords are the main breach. A secure password should contain:
| type | Example | Crack difficulty |
|---|---|---|
| weak password | 12345678 | Crack in seconds |
| medium password | HomeWiFi2023 | hours |
| Strong password | J5#k9$mL!pQ2 | several years |
4. Update firmware regularly
Router manufacturers will fix known vulnerabilities. Three high-risk vulnerabilities (such as CVE-2023-27917) exposed in the past 10 days have been fixed through updated patches.
5. Enable MAC address filtering
Only allowing known devices to access is not completely secure, but it can block most random attacks.
3. Hotspot related case warnings
A netizen shared his experience: due to the use of the default router password, the smart camera was hacked and private images were leaked. The post received more than 100,000 retweets, highlighting the importance of basic protection.
Summarize
WiFi security requiresEncryption, passwords, device managementStart from three aspects. In light of recent hot events, it is recommended that users check router settings once a month and pay attention to official vulnerability notices. Prevention is better than remedy, the sooner you act, the lower the risk!
