Cyber attacks are not an uncommon concept today. These malicious and deliberate attempts are made by several nefarious parties to breach the information system of a certain individual or organization. Ram Chary Everi mentions that usually the attacker seeks some kind of benefit by disrupting the network of the victim. Cybercrime has been increasing on a rapid scale as more number of attackers is trying to benefit from vulnerable business systems. These numbers are expected to go further up, as companies begin to incorporate digital elements in varying aspects of their operations.
Both individuals and businesses can suffer from major data leaks caused by distinctive types of cyber attacks. Ram Chary Everi mentions that to protect themselves from these threats, a person has to understand them properly as well. While malware and phishing are fairly familiar terms, there are still a number of cyber attacks that are less well known. To make sure that they have a robust security solution in place, one needs to be well-acquainted with the most common types of cyber attacks.
Here are some of the most common types of cyber attacks as underlined by Ram Chary Everi:
- Phishing and spear phishing: Phishing basically involves sending of emails that appear to be coming from a trusted source. The aim of this attack is to either spread malware, or to gain sensitive information or to spend malware. This is one of the easiest means to breach the privacy and security of a company. Spear phishing also has a similar outcome, but utilizes a more focused approach. Such attacks tend to need a bit more research on an individual or a target user group, than the typical phishing process.
- Password attacks and credential reuse: Many people fail to use strong passwords, even though the risks of not doing so are widely known. Hackers tend to use an array of password hacking techniques, right from using lists of common weak passwords to more complicated rainbow table attacks, to crack the password of a person. This becomes easier if the password has been reused. To prevent password attacks, one needs to educate users on phishing methods, encourage and enforce the use of strong, unique passwords, as well as implement an account lockout policy at their company.
- Denial-of-service attacks: These attacks can have devastating consequences on a business. The most common variants of such attacks include TCP SYN flood attack, ping-of-death, botnets, and teardrop attacks. Such attacks basically damage a business by flooding target web servers with requests, thereby stopping the regular user connection. This results in website downtime, subsequently leading to disappointed customer and reputation damage. They can even result in data losses and compensation payouts.
- Malware: Malware breaches a network with the help a vulnerability. These breaches usually happen when a user clicks a dangerous link or email attachment that then installs risky software.
There are several other types of cyber attacks that one may face today, in addition to the ones mentioned above.
