API Abuse API abuse arises when an attacker uses a programming interface in a way the application did not anticipate or did not restrict enough. An API is not merely a technical add-on to the application. It is often the main entrance to the data, the users, the orders, the payments and the administration.

Account Takeover Account takeover is the moment the attacker gains full control of an account — not only access, but the ability to change the password, the recovery mail address, the phone number and the second factor, while the real owner is shut out with no technical way back in on their own. Takeover is rarely the first stage of an attack. It is usually the destination of what came before: phishing, credential stuffing, token theft.

AiTM AiTM sits between the user and the real service. Classic phishing steals a password; AiTM steals the live session. The victim gets a link, lands on a proxy that looks exactly like the real login (because it forwards everything to the real site), enters credentials and even the MFA code — the proxy passes them through, the real service issues a session token, and the attacker captures that token.

Authentication Bypass An authentication bypass means the attacker reaches a protected part of the system without logging in the ordinary way. They need not know a password. Sometimes a flaw in the logic is enough, or an unprotected endpoint, a predictable token, a misconfigured proxy, or a gap between two steps of the login.

BGP Hijacking BGP hijacking is an attack, or a serious mistake, in which internet traffic is diverted by wrong routing. BGP is the protocol by which autonomous systems on the internet tell each other which path leads to particular IP ranges.

Backdoor A backdoor is a hidden way in. Once placed or opened, it lets the attacker return to the machine — with no password, no authorization and no entry in the ordinary records.

Brute-force attack A brute-force attack breaks into an account by trying to log in over and over: automated tools work through password after password until one takes. It succeeds against short, weak and common passwords, and against systems that put no limit on failed attempts. It is not clever — it is only fast, and it can run for days.

Business Email Compromise Business email compromise is not an ordinary fake email. The attacker breaks into business correspondence, or imitates it well enough that somebody in the company believes the request comes from the director, from finance, from a supplier, a lawyer or a partner. The aim is usually money, but it can also be a confidential document, a change of payment details, or an opening for the next phase of the attack.

Cloud lateral movement In the cloud, identities can assume roles — temporarily take on another identity's rights. It's built for legitimate delegation, but it becomes lateral movement when an attacker who got one identity chains the steps: identity A can become B, B can become C with more rights, C reaches another account. No new password at each step — just inherited delegation.

Kerberoasting Kerberoasting is an attack specific to Windows domain networks and Active Directory (AD). User logins are handled by the Kerberos protocol, which issues tickets as proof of identity. In a domain environment there are non-user accounts — service accounts — under which most background tasks and services run, such as databases and business applications. Service accounts are set up so that any user can request a ticket for access to a given service. The catch is that the ticket is encrypted with the service account's password.

MFA Fatigue MFA fatigue is social-engineering pressure applied to two-factor authentication. The attacker has the password, leaked or phished, but is stopped at the second factor — a confirmation the user has to approve on their phone. So the attacker starts the login over and over, burying the phone in approval requests. The arithmetic is simple: out of irritation, confusion, or the thought that it must be some glitch, the user approves one at some point — and the attacker is through the whole authentication.

Privilege Escalation Privilege escalation is the attempt by an attacker who already holds some level of access to widen their rights in order to move through the network. Escalation is rarely the first stage — it comes after entry through, say, an ordinary user account or a compromised service. It takes the attacker from the crack they slipped through to control of the whole system. There are two directions: vertical escalation, from an ordinary user to domain administrator, and horizontal, moving from one account to another user's resources at the same level of rights.
