Cybercriminals Use Your Devices

 

CybercriminalsThreat actors don’t always use their own hardware to commit cybercrimes. Sometimes, they use your resources to carry about malicious campaigns. Botnets are just one tool cybercriminals use to hijack your PCs or devices.

With distributed denial-of-service (DDoS) attacks on the rise, everyone wants to know what is a botnet exactly? In a nutshell, a botnet is a program that runs automated scripts over a network. And what do you get when you make a network of bots? A botnet, of course. 

Hackers that use malware to compromise computers and devices and use them as bots are known as bot herders. Computers or devices that become part of the botnet and follow the goals of command-and-control servers are usually innocent participants in some of the following schemes: 

1. DDoS attacks

The term was mentioned above, so you’re probably wondering what is a DDoS attack? To keep it brief, a DDoS attack is when a hacker tries to overwhelm a website with excessive traffic, often from a sea of bots in a botnet. Websites that are prepared for such attacks usually survive, but platforms run by small companies with few resources can suffer long-term damage to their business. 

2. Ad Fraud

Hackers use hijacked devices to send fake traffic to online ads and make money by defrauding marketers. 

3. Ransomware Attacks

With a Remote Desktop Protocol (RDP) powered by bots, a cybercriminal can breach network security, take advantage of exploits, and drop malware like spyware or ransomware. While spyware can help a hacker steal sensitive data, a threatening ransomware strain can help them blackmail organizations by holding their data hostage.
