Websites and PC both are under threat when you are connected, and in-between, some hackers try to do unfair practices by stealing the data of anyone, so to safeguard, you should know what the threat is.
Malware refers to spyware, ransomware, viruses, worms, and other malicious software. When a user clicks on a malicious link or attachment, the malicious software will be activated, causing the installation of dangerous software. Cisco reports that once the malware is activated, it can:
- Block access to critical network components (ransomware)
- Install other malware
- Secretly obtain information by transferring data from the hard drive (spyware)
- Change individual components to do system cannot run
Denial of service
Denial of service (DoS) is a network attack that floods a computer or network to not respond to requests. Distributed DoS (DDoS) performs the same operation, but the attack originates from a computer network. The Internet Attackers often use flood attacks to interrupt the “handshake” process and perform DoS. Various other techniques can be used, and some cyber attackers use the time when the network is disabled to launch other attacks. Jeff Melnick of Netwrix, an information technology security software company, claims that a botnet is a DDoS. Millions of systems can be infected with malware and controlled by hackers. Botnets, sometimes called zombie systems, target and overwhelm the processing power of the target. Botnets are located in different geographic locations and are difficult to track.
A man-in-the-middle (MITM) attack occurred when a hacker inserted a two-party transaction. According to Cisco, after interrupting traffic, they can 먹튀 data. MITM attacks usually occur when visitors use unsecured public WiFi networks.
Structured Query Language (SQL) injection is a network attack, which is the use of SQL to insert malicious code into the server. When infected, the server will post information. Submitting malicious code is as simple as typing malicious code into the search box of a vulnerable website.
