Types of Cyberattacks and other terms from the world of cyber security

Intro

It’s convenient to name drop different types of cyber attacks at a party. I often struggle to name more than a few. I will try to maintain a running list of them.

But I find you cannot speak about cybersecurity unless you also have a basic understanding of information technology so I am including some of those terms as well.

As I write this I am painfully aware that you could simply ask ChatGPT to generate a list of all relevant terms in cybersecurity along with their definitions – at least I think you could – and come up with a much better and more complete list. But I refuse to go that route. These are terms I have personally come across so they have special significance for me personally. In other words, this list has been organically grown. For instance I plowed through a report by a major vendor specializing in reviewing other vendor’s offerings and it’s just incredible just how dense with jargon and acronyms each paragragh is: a motherlode of state-of-the-art tech jargon.

Baitortion

I guess an attack which has a bait such as a plum job offer combined with some kind of extortion? The usage was not 100% clear.

Collision attack

I.e., against the MD5 hash algorithm as done in the Blast RADIUS exploit.

Credential Stuffing Attack

I.e., password re-use. Takes advantage of users re-using passwords for different applications. Nearly three of four consumers re-use password this way. Source: F5. Date: 3/2024

Password spraying

A type of attack in which the threat actor tries the same password with multiple accounts, until one combination works. 

Supply Chain attack
Social Engineering
Hacking
Hacktivist

I suppose that would be an activitst who uses hacking to further their agenda.

Living off the land
Data Breach
Keylogger
Darknet
Captcha
Click farms
Jackpotting

This is one of my favorite terms. Imagine crooks implanted malware into an ATM and were able to convince it to dispense all its available cash to them on the spot! something like this actually happened. Scary.

Overlay Attack

Example: When you open a banking app on your phone, malware loads an HTML phishing page that’s designed to look just like that particular app and the malware’s page is overlaid on top.

This is particularly disturbing to me because there is a human element, a foreign component, crypto currency, probably a type of slave trade, etc. See the Bloomberg Businessweek story about this.

An attacker can leverage path traversal sequences like “../” within a request to a vulnerable endpoint which ultimately allows access to sensitive files like /etc/shadow.

Use-after-free (UAF)

use-after-free vulnerability occurs when programmers do not manage dynamic memory allocation and deallocation properly in their programs.

Cold boot attack

A cold boot attack focuses on RAM and the fact that it is readable for a short while after a power cycle.

CVE

CVEs, or Common Vulnerabilities and Exposures, are a maintained list of vulnerabilities and exploits in computer systems. These exploits can affect anything, from phones to PCs to servers or software.  Once a vulnerability is made public, it’s given a name in the format CVE–. There are also scoring systems for CVEs, like the CVSS (Common Vulnerability Scoring System), which assigns a score based on a series of categories, such as how easy the vulnerability is to exploit, whether any prior access or authentication is required, as well as the impact the exploit could have.
