What is a SQL injection attack? The so-called SQL injection attack is an attacker inserting a SQL command into a Web form's input domain or a page request query string, tricking the server into executing a malicious SQL command.

Recently, Web SQL Injection attacks, JS scripts, and HTML scripts appear to be more intense. Many websites are plagued by such attacks. They are not immediately repaired as they do with host vulnerabilities. WEB attacks make us very inconvenient to prevent or repair them. HOOO ...... The greatest pain for a webmaster is this. How can we ensure that our passwords are strong but can always be obtained by attackers? But how can we achieve real security? First, do not associate your password with yo

A few weeks ago, someone found a new zero-time-difference Adobe Acrobat/Reader vulnerability on the Internet and immediately began to exploit it.
