What is a bot attack?

A bot attack is a type of cyber attack that uses automated scripts, or bots, to disrupt websites, steal data, make fraudulent purchases, or perform other malicious actions. These attacks target websites, servers, APIs, and other endpoints to steal sensitive information or damage infrastructure.

What is a bot?

A bot, short for “robot,” is a software program designed to automatically perform repetitive tasks. Bots can be beneficial, such as search engine bots that index websites or customer service bots that answer questions. However, bots can also be malicious. Malware bots can infect computers to steal information or disrupt services, and bots can carry out attacks like distributed denial-of-service (DDoS) to overwhelm websites with traffic.

Types of bot attacks

Bot attacks come in various forms, each designed to achieve specific malicious goals. Any bot action that violates a website’s Terms of Service or Robots.txt rules is considered malicious.

Common types of bot attacks include:

Credential stuffing: Using stolen login credentials to gain access to websites by attempting multiple logins from different devices and IP addresses.
Web and content scraping: Bots download content from websites to use in future attacks by sending a series of HTTP GET requests and copying the information quickly.
DoS and DDoS attacks: Networks of infected machines overwhelm servers or networks, causing outages and downtime.
Brute force password cracking: Bots try every possible password combination to gain unauthorized access to accounts.
Click fraud: Bots click on pay-per-click ads to generate fake revenue or deplete a competitor’s ad budget by imitating human behavior.

Why do bot attacks happen?

Bad actors may launch bot attacks for various reasons, including financial gain, service disruption, extortion, and ideological motivations. Hackers may steal personal and financial information to sell on the dark web or cause disruptions to e-commerce sites and social media platforms. Some attacks are aimed at extorting money through ransomware, while others are carried out by hacktivists targeting organizations or government entities.

How to prevent bot attacks

To prevent bot attacks, websites can implement several strategies:

Multi-Factor Authentication (MFA): Requiring multiple forms of identity verification to prevent unauthorized access.
Allowlists and Blocklists: Managing lists of approved and denied IP addresses to filter out malicious traffic.
Web Application Firewalls (WAFs): Use a web application firewall that leverages behavioral analysis, machine learning, and fingerprinting like the Sucuri firewall to detect and block malicious bots in real time.

Implementing measures to detect and block malicious bots is key to protecting against bot attacks.

How are bots used for attacks?

Bots can be used to execute various fraudulent activities, such as distributing malware, stealing credentials, generating fake traffic, and launching attacks on competitors. Large-scale bot attacks, often carried out using botnets, can include DDoS attacks, phishing, brute force attacks, and more. These attacks can disrupt services, steal data, and cause significant damage to businesses.

Types of Bot Attacks

Bot attacks continue to evolve, becoming more sophisticated and capable of mimicking human interactions. Common types of bot attacks include:

Phishing attacks: Automated bots send thousands of phishing emails to steal personal information.
Spambot attacks: Bots post spam comments on websites to promote other sites or disrupt services.
Scalper and ticketing bots: Automated bots buy tickets or limited stock items to resell at higher prices.
Inventory denial bot attacks: Bots deplete e-commerce inventories, causing disruption and potential financial loss.

Signs of a bot attack

Signs of a bot attack vary and can include one or more of these symptoms:

Abnormally high page views: Sudden spikes in web traffic.
High bounce rates: Bots may leave a site quickly, causing higher than normal bounce rates.
Unusual session durations: Bots browsing sites at abnormal speeds compared to average website visitors.
Junk conversions: Fake account creations or form submissions.
Traffic from unexpected locations: Surges in traffic from unlikely regions.

Bot attacks are on the rise, with significant increases in certain regions. These attacks can be devastating, causing financial loss, reputational damage, and operational disruption.

Regular website monitoring, security audits, and the use of advanced bot solutions like the Sucuri web application firewall are key for defending against these persistent threats.
