Cybersecurity threats: Phishing, Ransomware, and Credential Stuffing explained

Cybersecurity threats: Phishing, Ransomware, and Credential Stuffing explained

Cybersecurity is not about compliance or trying to do damage control after a security breach has happened. It is more about being proactive and taking necessary steps, so that a breach can be prevented in the first place. Addressing online security concerns should be the first priority. In this post, we are discussing three serious cybersecurity threats in depth. 

  • Phishing

Hackers use phishing for exploiting human vulnerabilities. A typical phishing email usually contains instructions that are user is expected to follow. Since the email address looks legit, users usually fall prey to the instructions. Some emails may include scare tactics, where someone is given a limited period to furnish certain details, while in other cases, a link or download is included, which may contain malware. There is also something called spear phishing, which is very targeted to select users, and hackers usually have information in advance that’s used to their benefit. 

Phishing emails, however, are not hard to detect. Most such emails have some trick asking for information, and typically, the email address or the content will have grammatical and other spelling errors. 

  • Ransomware

A huge number of companies have suffered ransomware attacks in recent times. Ransomware is a type of malware, which is used for data and information encryption. In most cases, an unsuspecting user downloads a file that can install ransomware on a workstation, and once in place, the malware can encrypt data. The hacker will then ask for a ransom, promising a decryption key in return. 

Ransomware attacks are often related to trojan and can be even used for creating backdoors. This is the precise reason why employees must know about the risk and how they can handle downloads and links better. Just clicking a link can download a trojan, which can eventually lead to a ransomware attack.

  • Credential stuffing

Credential stuffing is a type of cyberattack, where credentials that have been obtained from a previous data breach are used by hackers to login and get access to an unrelated service or resource. Previous data breaches can contain credentials of millions of users, and hackers just try to use the same to attack businesses and users, which is the crux of credential stuffing. The best idea would be to change passwords frequently, so that old passwords or hacked credentials cannot be used. Another great step for better cybersecurity is to use multifactor authentication. 

Do not let your guard down when it comes to cybersecurity threats!
