Different nature of attacks in cybersecurity

 1.The Persirai botnet

In 2017, an Internet of Things (IoT) botnet, Persirai, targeted over 1,000 different models of Internet Protocol (IP) cameras, accessing open ports to inject a command that forced the cameras to connect to a site which installed malware on them. Once the malware was downloaded and executed, it deleted itself and was therefore able to run in memory to avoid detection.

Over 122,000 of these cameras from several different manufacturers were hijacked and used to carry out distributed denial-of-service (DDoS) attacks, without the knowledge of their owners. A DDoS attack occurs when multiple devices infected with malware flood the resources of a targeted system.

The IoT is connecting more and more devices, creating more opportunities for cybercriminals to attack.

2.Equifax Inc.

In September 2017, Equifax, a consumer credit reporting agency in the United States, publicly announced a data breach event: Attackers had been able to exploit a vulnerability in its web application software to gain access to the sensitive personal data of millions of customers.

In response to this breach, Equifax established a dedicated website that allowed Equifax customers to determine if their information was compromised. However, instead of using a subdomain of equifax.com, the company set up a new domain name, which allowed cybercriminals to create unauthorized websites with similar names. These websites were used to try and trick customers into providing personal information.

Attackers could use this information to assume a customer’s identity. In such cases, it would be very difficult for the customer to prove otherwise, given that the hacker is also privy to their personal information.

Redis installation in Red Hat Linux

 In this post we will see step by step installation of Redis service in Redhat/CentOS operation system. To install Redis, run this command in terminal -dnf install redis This command will install the redis service in your machine. Verify installation -systemctl status redis -systemctl start redis -systemctl enable redis Note: Before start redis service set Linux Kernal overcommit memory to 1 by adding vm.overcommit_memory = 1 to /etc/sysctl.conf file. Why we should do that: As we know redis is in memory data store. It primarily uses RAM to store data. Redis and other processes use RAM memory. We set vm.overcommit_memory = 1 to make sure Kernal not overcommit the memory by allocating memory to new program which required more memory than available memory. In this scenario OOM (Out Of Memory) killer terminate the rest of processes. We also restricting Kernal not to terminate the important services running and also stop swapping redis and other importance service to device i/o device,...
