Tipici attacchi Hacker su siti Word Press

Tipici attacchi Hacker su siti Word Press

1. Brute Force Login

Obiettivo: Forzare username e password dell’amministratore.
Come: Tentativi ripetuti automatizzati di login.
Contromisure: Limitare tentativi di login, usare 2FA, cambiare URL di login, CAPTCHA.

2. SQL Injection

Obiettivo: Eseguire comandi SQL malevoli nel database.
Come: Campi input non filtrati (es. form di ricerca).
Contromisure: Validazione/sanitizzazione input, uso di plugin aggiornati e sicuri.

3. Malicious File Uploads

Obiettivo: Caricare script malevoli (es. PHP) per ottenere accesso al sito.
Come: Moduli di upload non protetti.
Contromisure: Limitare estensioni accettate, evitare esecuzione dei file uploadati.

4. Cross-Site Scripting (XSS)

Obiettivo: Iniettare codice JS nel sito per rubare cookie o dirottare sessioni.
Come: Commenti o input non sanificati.
Contromisure: Escaping/validazione output, plugin sicuri.

5. Cross-Site Request Forgery (CSRF)

Obiettivo: Indurre l’utente loggato a compiere azioni non desiderate (es. cambio password).
Come: Link o script malevoli caricati nel browser dell’utente.
Contromisure: Token CSRF, validazione lato server.

6. Vulnerabilità nei plugin o temi

Obiettivo: Usare vulnerabilità note per ottenere accesso o eseguire codice remoto.
Come: Plugin non aggiornati, codici personalizzati mal scritti.
Contromisure: Aggiornamenti regolari, plugin/theme affidabili (evitare versioni nulled/crackate).

7. XML-RPC Exploits

Obiettivo: Abusare della funzione xmlrpc.php per:
Brute force
Amplificare DDoS
Pubblicare post spam
Contromisure: Disabilitare xmlrpc.php se non necessario o limitarne l’accesso.

8. Backdoors and Web Shells

Obiettivo: Ottenere accesso persistente al sito anche dopo la pulizia.
Come: Codice nascosto nei temi/plugin o nei file core.
Contromisure: Scansione malware (Wordfence, Sucuri), hardening del file system.

9. Redirect Malevoli e SEO Spam

Obiettivo: Inserire link a siti spam o reindirizzare traffico verso siti fraudolenti.
Come: Modifica di file .htaccess, wp-config.php, functions.php.
Contromisure: Monitoraggio file critici, plugin di sicurezza, blocco modifiche.

10. Denial of Service (DDoS)

Obiettivo: Rendere il sito irraggiungibile sovraccaricandolo di richieste.
Come: Bot, traffico fittizio, vulnerabilità dei plugin.
Contromisure: CDN con protezione DDoS (es. Cloudflare), WAF.

Common Hacker Attacks on WordPress Sites

Discover the most common hacker attacks targeting WordPress websites, including brute force login attempts, SQL injections, XSS vulnerabilities, and plugin exploits. Learn how to protect your site with essential security practices and recommended tools.

Common Hacker Attacks on WordPress Sites

Common Hacker Attacks on WordPress Sites

1. Brute Force Login

Automated attempts to guess the administrator’s username and password. It’s important to use strong passwords, limit login attempts, enable two-factor authentication (2FA), and change the default login URL.

2. SQL Injection

Hackers inject malicious SQL commands into input fields to manipulate or access the database. This can be prevented by sanitizing inputs and using secure, updated plugins.

3. Malicious File Uploads

Attackers upload harmful scripts (e.g., PHP) through vulnerable forms. To mitigate, restrict allowed file types and prevent execution of uploaded files.

4. Cross-Site Scripting (XSS)

Injects JavaScript code into the site via comments or forms to hijack sessions or steal data. Avoid this by validating and escaping user input/output properly.

5. Cross-Site Request Forgery (CSRF)

Tricks authenticated users into performing unwanted actions. Protection includes CSRF tokens and strict validation of requests.

6. Plugin or Theme Vulnerabilities

Outdated or insecure plugins/themes may expose the site to threats. Use only trusted sources and keep everything up to date.

7. XML-RPC Exploits

The xmlrpc.php file can be used for brute force or DDoS attacks. If not required, it should be disabled or restricted.

8. Backdoors and Web Shells

Malicious code that provides persistent access even after malware removal. Regularly scan and monitor critical system files.

9. Malicious Redirects and SEO Spam

Attackers modify core files (e.g., .htaccess) to redirect users or inject spam links. Monitor for unauthorized file changes.

10. Denial of Service (DDoS)

Overloads the server with fake traffic, making the site unreachable. Mitigation includes CDN protection, web application firewalls (WAF), and server-level rate limiting.
