It’s very targeted and often used for high-value targets. With the right knowledge, they can capture the traffic between these points and “sniff” the traffic. Since these “switches” regulate the flow of data between ports, it’s a valuable target for sniffers. This is when a hacker actively targets a point-to-point network device. Hackers infect computers via unsafe websites and phishing scams by tricking users into downloading the software via attachments or unsafe links. If that sounds intrusive, it’s because it is. They then save all of the packets and later dig through them. Hackers use software to change a computer’s settings to collect these data packets that are traveling over the network. What hackers are doing is intercepting packets of information being sent over a network, using software to decode and interpret it and then using that against you. These “wiretaps” can monitor websites you visit, anything you have downloaded or uploaded, and more in real-time. ![]() The legitimate purpose of sniffers is to make sure traffic across a network is smooth and uninterrupted. The reality is, the technology was intended for legal purposes to monitor traffic but has been adopted by criminals. Sniffers are either programs or even hardware devices that spy on internet activity. They want your login information, including passwords, banking information or credit card information, personal messages and emails or anything that could help them steal your identity. In a way, that’s what cybercriminals are doing when they implement a sniffing attack.Ĭriminals are looking for specific things during a sniffing attack. The closest comparison to sniffing in the “real world” of popular culture is when a police detective bugs a telephone line to intercept a call and secret information. Knowing what you’re up against is imperative to practice good digital hygiene. To truly protect yourself, your wallet and your time, you need to protect your data. The main goal of sniffing attacks is to steal data and personal information.Īs you have learned, if you are following along with our series on security threats, personal data can be extremely valuable for hackers and cybercriminals and costly for you if it’s stolen. They allow hackers to sniff out data packets from both public and private networks. Packet sniffers, more generally known as sniffers, are almost like a dog sniffing information that’s crossing a network. So what is sniffing and how can you prevent it? One of the latest, tricky techniques is known as packet sniffing. It is a necessity for hackers as security systems and software updates are continuously blocking their attacks. ![]() The world of hacking is getting more and more complex as the years go by. Take preventative steps to prevent packet sniffing, one of the most intrusive techniques used by hackers to steal personal information.
