What is a ‘bot’? This refers to a software application that is programmed to perform specific tasks and can do this with or without the necessity for human interaction. This can aid in a faster and more accurate application that is cost effective and scalable.
Legitimate uses of bots are for task automation, performing repetitive tasks, data processing and indexing. Bots have gained more recognition through artificial intelligence with the emergence of chatbots. Chatbots can engage in conversations with the user through voice or text interfaces.
Cyber criminals have embraced the use of bots to formulate attacks that are stealthy and debilitating. A botnet is a network of infected, Internet-connected devices that are controlled by malware. By combining computing power, the botnet can leverage compromises of unlimited devices. Some common attacks through the use of this automation are:
- DDoS attacks-A Distributed Denial of Service can overwhelm a server with a flood of traffic. This halts Internet connectivity and disrupts business.
- Malware distribution-Bots can distribute malware and malicious links.
- Credential stuffing -Automated bots are used to test stolen credentials on various websites and applications.
- Account takeover – A scripted bot attack that uses stolen or brute-force to gain unauthorized access to the user’s account.
To help defend against a bot attack it is important to educate end users. Users can be the first line of defense and assist with early recognition of suspicious behaviors. Continuous monitoring of user activity and traffic is crucial. Consider port blocking, allow and block listings. Implement multi-factor authentication to make it more difficult for the crooks to gain unauthorized access.
