Instead, the malicious code only runs in the user's browser when they visit the attacked website, where it directly targets the visitor. Cross-Site Scripting (XSS)Ĭross-site scripting (XSS) attacks also involve injecting malicious code into a website, but in this case the website itself is not being attacked. For example, if an SQL server is vulnerable to an injection attack, it may be possible for an attacker to go to a website's search box and type in code that would force the site's SQL server to dump all of its stored usernames and passwords. SQL (structured query language) is a programming language used to communicate with databases, and can be used to store private customer information such as credit card numbers, usernames and passwords (credentials), or other personally identifiable information (PII) – all tempting and lucrative targets for an attacker.Īn SQL injection attack works by exploiting any one of the known SQL vulnerabilities that allow the SQL server to run malicious code. SQL Injection AttackĪn SQL injection attack specifically targets servers storing critical website and service data using malicious code to get the server to divulge information it normally wouldn’t. To combat phishing attempts, it’s essential to understand the importance of verifying email senders and attachments or links. If you click the link, it may send you to a legitimate-looking website that asks you to log in to access an important file – except the website is actually a trap used to capture your credentials.

Once malware is in your computer, it can wreak all sorts of havoc, from taking control of your machine, to monitoring your actions and keystrokes, to silently sending all sorts of confidential data from your computer or network to the attacker's home base.Īttackers will use a variety of methods to get malware into your computer, but at some stage it often requires the user to take an action to install the malware. Malware refers to various forms of harmful software, such as viruses and ransomware. ![]() ![]() Let's take a look at some of the most common types of cyberattacks seen today. ![]() Whether you're trying to make sense of the latest data-breach headline in the news or analyzing an incident in your own organization, it helps to understand different attack vectors. They draw upon common hacking techniques that are known to be highly effective, such as malware, phishing, or cross-site scripting (XSS). Similarly, when a criminal is trying to hack an organization, they won't try something novel unless absolutely necessary. ![]() But there are strategies that, over time, have proven to be effective. If you've ever studied famous battles in history, you'll know that no two are exactly alike.
