4 Common Types of Remote Attacks
A remote attack refers to a malicious attack that targets one or more computers on a network. Remote hackers look for vulnerable points in a network’s security to remotely compromise systems, steal data, and cause many other kinds of problems. Some of the most types of remote attacks are:
1. Domain Name System (DNS) Poisoning
The DNS server is tricked into accepting falsified traffic as authentic. Users are then redirected to fake websites where they unknowingly download malicious content like viruses which the attackers exploit further to steal data or compromise systems.
2. Port Scanning
Hackers use port scanning software to find open ports on a network host. To do this, they send packets to each port and determine which ports are open based on the response type. While the scanning itself does not cause damage, threat actors do utilize this method to exploit potential vulnerabilities on the network, and then gain access to it.
3. Password Spraying
Attackers will identify a large number of usernames (accounts), and attempt to guess the passwords for those accounts to gain unauthorized access. They usually use a single commonly-used password in a particular timed interval, e.g., one password a week, to remain undetected and avoid account lockouts.
4. Phishing
Phishing is one of the most commonly-used methods to gain remote access to corporate networks. Bad actors send emails to potential victims containing malicious links or attachments.
How Organizations Can Protect Themselves from Remote Hackers
Here are some ways remote hackers hack into remote access tools to manipulate enterprise systems, steal data, and disrupt businesses.
1. Virtual Private Network (VPN) Attacks
The problem: Many organizations rely on VPNs to enable remote access for employees. But not all VPNs provide end-to-end encryption, and many still rely on weak or outdated encryption. Remote hackers exploit these weaknesses to compromise enterprise systems.
Exploit Kits: Overview
Cybercrime was once the domain of a tiny handful of people with excellent technical skills who leveraged their abilities for malicious acts. However, cybercrime had grown now into a multibillion-dollar business, with threat actors profiting from the sale of malware, ransomware, and exploit kits on Dark Web forums – which is the hidden internet.
Exploit-Kit-as-a-Service: EKaaS
Exploit-kit-as-a-Service is a SaaS (Software as a Service) business model that allows people with less technical knowledge to buy and rent pre-developed exploit kits. This kit can compromise vulnerable systems, increase the attackers’ income, and increase the malware infection rate.
Exploit Kits: Workflow
In the first step, attackers deceive users into accessing genuine sites that have been infected with a sophisticated exploit kit.
Security Best Practices to Counter Exploit Kits
IT System administrators should ensure that all corporate systems, devices, and software are running with the latest security updates.
Conclusion
Exploit kits are more complex tools that contain many exploits and are designed to automatically exploit vulnerabilities on victims’ PCs while they surf the web. Since they are highly automated and adaptive, they have become one of hackers’ preferred strategies for large-scale malware and ransomware distribution.
