Tracking and detecting login attempts, failures, and brute-force attacks is necessary for enhancing an organization's security posture.

Consent phishing

Consent phishing is a variant of phishing attacks, where the attacker attempts to trick users into authorizing a malicious app or integration. Once the malicious app is authorized, it can be used to compromise accounts, exfiltrate data, or exploit further attack vectors.

Credential stuffing

Credential stuffing attacks exploit databases of previously compromised username and password combinations, attempting to log in to target accounts using these breached credentials.

Cross-site scripting (XSS)

Cross-site scripting is an attack that injects malicious scripts into a legitimate and trusted website. These scripts can execute when an unsuspecting user visits the website, potentially accessing sensitive data and session information, or installing malware.

Data breaches

A data breach refers to any event where unauthorized users steal sensitive information from an organization, often including personally identifiable information (PII) or financial data that can be sold on the black market.

Distributed denial-of-service (DDoS) attacks

A DDoS attack aims to overwhelm and crash a web server or online service by flooding it with more traffic than it can handle. Attackers often use botnets to execute these attacks in a distributed manner.

Domain name system (DNS) hijacking

DNS hijacking, also known as DNS redirection or DNS poisoning, involves redirecting domain name queries to a malicious website, often containing malware or unwanted content.

Drive-by attacks

In a drive-by attack, malicious code is automatically downloaded to a user's device, typically when they visit a compromised website, without the user taking any explicit action.

Exploits

An exploit is a malicious application or script that takes advantage of a vulnerability in hardware, networks, or applications, allowing attackers to gain control, steal data, or escalate privileges.

Golden ticket attacks

A golden ticket attack occurs when an attacker gains control over a domain's key distribution service, enabling them to produce unauthorized tickets that grant access to network resources within the domain.

Malware

Malware, or malicious software, can spread through email attachments or links to malicious websites, infecting endpoints and causing a wide range of issues, from data theft to system disruption.

Ransomware

Ransomware is malware that prevents users from accessing their data or systems, often by encrypting files, and demands a ransom payment in exchange for the decryption key.

Supply chain attacks

Supply chain attacks target an organization by compromising a third-party resource, such as a vendor or service provider, as a means of gaining access to the intended victim.

Phishing and social engineering attacks

Phishing and social engineering attacks rely on deception and manipulation to trick users into divulging sensitive information or taking actions that compromise security, such as clicking on malicious links or downloading malware.
