✅Malware: It is any kind of software that is designed to cause damage to a single computer, server, or computer network.
Like- Ransomware, Spyware, Worms, viruses & Trojans are all varieties of malware.
✅Spoofing: Cybercriminals try impersonating a bank’s URL with a website that is quite similar to the original one and has similar functions as well.
✅Phishing: it is attempting to obtain sensitive information such as credit card details, etc. for fraudulent activities, by disguising oneself as an authentic, trustworthy entity via electronic communication
✅Denial of Service attacks: It is an attack meant to shut down a machine or network, making it inaccessible to its intended users.
✅Man-in-the-middle (MitM) attacks: They occur when attackers insert themselves into a two-party transaction.
✅Structured Query Language (SQL) Injection: SQL stands for a programming language used to communicate with databases.
