What is a social engineering attack?
Social engineering is using human interaction (social skills) to obtain or compromise data/information about an organization or its computer systems. This information can them be used to deploy an attack and/or penetrate a network further. Social engineering attacks are particularly dangerous because they prey on our human instincts, interactions and dealings with people and our contextual environment. An attacker may not fit the stereotype we hold in our heads. Social engineering preys on the fact that humans will have our guard up for natural signs of danger and natural enemies, but things get fuzzy when the distinction is not so clear. In social engineering, the attacker may seem unassuming, respectable…

CSIRT—Computer Security Incident Response Team is a concrete organizational entity (i.e., one or more staff) that is assigned the responsibility for coordinating and supporting the response to a computer security event or incident.

How Was Colonial Pipeline Hacked/Breached? Because of One Single Employee’s Compromised Password?

All a malicious actor would need is a password to an account, and just like that (*finger snap!*), you’ve invited them in, like welcoming Count Dracula through your front door for Sunday dinner. So, Colonial, right…here’s the latest. After an analysis of the cyberattack on Colonial Pipeline, investigators suspect that hackers obtained the password from the dark web (think a marketplace for illicit activity) where such info is available for the…

A false positive is an outcome where the model incorrectly predicts the positive case. Ex: Downloaded file is NOT malware, but the A.V. detected it as malware.

What is Attack Surface?
Attack surface. First thing I start thinking is the surface area, or the exposed area that is susceptible to a cyber onslaught by threat actors, or bad people with malicious intent. According to Wikipedia: “The attack surface of a software environment is the sum of the different points (for “attack vectors”) where an unauthorized user (the “attacker”) can try to enter data to or extract data from an environment. Keeping the attack surface as small as possible is a basic security measure.” via Wikipedia “KEEPING THE ATTACK SURFACE AS SMALL AS POSSIBLE IS A BASIC SECURITY MEASURE.” **clap, clap** Does that last line stick out to anyone else?? It should.…

An arbitrary code execution vulnerability is a security flaw in software or hardware allowing arbitrary code execution. A program that is designed to exploit such a vulnerability is called an arbitrary code execution exploit.
