______ attack is the practice of sending messages that appear to be from trusted sources with the goal of gaining personal information or influencing users to do something. It combines social engineering and technical trickery. Unsuspecting users open the email and may provide protected information or download malware. EXAMPLE An attacker could send an email with a file attachment or a link to a fake website that loads malware onto a target's computer.

<p>Phishing</p> Signup and view all the answers

______ attacks are a very targeted type of phishing activity. Attackers take the time to conduct research into targets and create messages that are personal and relevant, and thus likely more effective. EXAMPLE An attacker collects a target's details from social media and calls the target pretending to be a representative from the bank. The attacker advises the account is compromised and asks the target to transfer money to a "safe" bank account. The attack is convincing because of the attacker's apparently legitimate knowledge.

______ is a catch-all term for malicious software. It is any software designed to perform in a detrimental manner to a targeted user without the user's informed consent. It often triggers secretly when a user runs a program or downloads a file, which can often be unintentional. Once active, malware can block access to data and programs, steal information, and make systems inoperable. EXAMPLE Within the various types of malware, you will find examples related to their function, such as keyloggers (which captures a victim's keystrokes) or ransomware (which holds a victim's files captive in exchange for a ransom payment).

A MitM attack occurs when hackers insert themselves in the communications between a client and a server. This allows hackers to see what’s being sent and received by both sides. EXAMPLE An attacker could set up a "free" WiFi hot spot in a popular public location. Anyone who connects to that WiFi network could have their communications examined by the attacker, who may redirect victims to fake log-in screens or insert advertisements over webpages.

DNS is one of the core protocols used on the internet. Basically, the DNS protocol allows a computer to resolve a domain to an IP address, which allows a user to, for example, reach BMW’s main website by typing “bmw.com” instead of writing an IP address that is hard to remember. DNS is used almost everywhere. As a core protocol of the internet, lots of attack vectors directly target DNS, including DNS spoofing, domain hijacking, and cache poisoning (just to name a few). EXAMPLE In 2016, the DNS service provided by a company called Dyn was attacked. This resulted in major outages across most of the US, leaving millions of Americans unable to access or use internet services.

SQL allows users to query databases. SQL injection is the placement of malicious code in SQL queries, usually via web page input. A successful attack allows common commands to be run. This can include deleting the database itself. SQL injection is one of the most common web hacking techniques. EXAMPLE In the UK, two teenagers managed to target TalkTalk's website in 2015 to steal hundreds of thousands of customer records from a database that was remotely accessible.
