Fast facts about botnets:
- Botnets can be used to commit DDoS attacks, and any individual computer on the botnet can also be used as a puppet for other kinds of attacks, such as delivering viruses or sending other malicious traffic.
- Infected computers, often called âzombies,â can execute commands in the background without their ownersâ knowledge.
- Botnets-for-hire often come with user interfaces such as dashboards and graphic front ends that make them more user-friendly for customers.
Deep dive on botnets:
Todayâs Internet is an Internet of Things (IoT), and many of those âThingsâ, from wearable watches to security cameras to smart appliances, have a dangerous combination: an ability to make web traffic requests and poor security hygiene.
With the right software, bad actors can exploit vulnerabilities in both normal computers and IoT devices to turn them into an army of puppet machines known as a botnet.
So, what can someone do with a botnet-for-hire? For as little as $20, they could use it to commit a distributed-denial-of-service (DDoS) attack against a website of their choice, knocking it offline until the attack stops or the website employs DDoS protection. For more money than that, they can even be used to conduct ransomware attacks, such as with the Qakbot botnet recently dismantled by the FBI.
An affected computer, sometimes called a âzombie,â can also be used to carry out different kinds of attacks without the ownerâs knowledge. Using botted computers in this way grants a layer of anonymity to attackers and expands their reach.
One example of an attack a zombie computer can carry out is a chatbot phishing scheme. Threat actors can target followers of banks and other financial institutions by pretending to represent these institutions and messaging customers as though theyâre seeking customer service feedback.
After a while, and after gaining the consumerâs trust, the bot then asks the user about a âsuspicious charge,â which of course never happened. When the consumer says the charge wasnât theirs, theyâre directed to a phishing link disguised as a way to secure their account or asked to share a one-time-password (OTP), compromising their account.
Botnets for hire can give fraudsters a broader net to cast for not much extra moneyâand whatâs a good deal for fraudsters can spell bad news for consumers and fraud fighters. Automated bot detection and multiple authentication factors can help protect users and websites from these types of attacks.
