Cybercrime threats and attacks

Different types of cyber attacks implemented by cybercriminals and hackers

Malware Malware is a type of virus that is used to attack a system such as trojan, adware and spyware, to name a few. Someone who has downloaded a certain file that may have infected their computer using spyware to steal their data, adware to bombard them with adverts and a "trojan" that is disguised as something harmless but contains an infectious virus that can corrupt your data.
Phishing A Phishing attack is when a cybercriminal sends emails or messages, which appear as if they have come from a legitimate source (such as banks, shopping sites, etc) to someone hoping that they would click to open the attached files or the links and install malware to steal data and financial information (i.e. credit card)
Middle-man attack Here the hacker gains access to the "information path" between the targeted user's device and the websites' servers. The hacker's device takes over the IP address being used by the targeted device, by doing this the communication line between the targeted device and the website's servers is secretly intercepted and all the information going back and forth is seen by the hacker. This commonly happens with unsecured Wi-Fi networks and also through malware
Password Attack This is one of the easiest ways to hack a system. A password is cracked using either common passwords or all possible combinations of passwords using a “dictionary codex” or by simply recording the keystrokes as someone enters a password

Industrial Cybersecurity Threats

Cyber-attacks are not just confined to individuals, but also to public and private organisations too. The cyberattacks carried out in such places are more deadly and can result in huge losses. There are many motives of such attacks, starting from tampering with crucial data to financial gains

APT (Advanced Persistent Threat)

Various government organisations and large corporations face the Advanced Persistent Threat, in this form of attack, hackers gain access to networks for a prolonged period. In order to continuously gain confidential information

APT Advanced Persistent Threat

DDoS (Distributed Denial Of Service)

Denial Of Service is when networks are flooded with traffic, which leaves legitimate service requests unattended. A variant of this is DDoS, where multiple systems are used to launch the attack by cybercriminals.

DDoS (Distributed Denial Of Service)

SQL Injection Attack

When a hacker manipulates a standard SQL query in a database-driven website, it is known as an "SQL Injection Attack". By doing this, hackers cab view, edit and delete tables from databases in the system.

Cybersecurity solutions

Different ways to secure yourself from cybersecurity threats

Firewall Installing a "firewall", creates a virtual wall between the user's computer and the internet. A firewall filters the incoming and outgoing traffic from the user's device to safeguard your network and a firewall can be either software applications or hardware reinforcements.
Honeypots This is called a "honeypot" because like a flower that attracts bees, a "dummy computer" or "virtual machine" attracts attackers, deceiving them into going into a device that does not exist. Hence, protecting the main system and surfing the net freely
Alphanumeric Passwords Using passwords that have a mix of letters, numbers, different cases, unique characters and symbols. Making a password hard to guess and being quite long in character length too. I.e. Cyb_erS3cu^rity!
Antivirus Software There are many antivirus software that users can install that helps detects malware and trojans in the systems or device, also prevents it from entering the system or doing anything malicious
Carefully opening emails By making sure we check our emails carefully, not opening anything from unknown senders and even marking it as junk or phishing emails in our email inboxes
