Malware term used to describe malicious software, like spyware, viruses, ransomware, and worms. Through a vulnerability, Malware breaches a network, typically when a user clicks a dangerous link or email attachment that then installs risky software. Once inside the system, malware can do the following things:
- Blocks access to key components of the network (ransomware)
- Installs additional harmful software or malware
- By transmitting data, covertly obtains information from the hard drive (spyware)
- Renders the system inoperable and Disrupts certain components
Phishing is an increasingly common cyberthreat. Phishing is the practice of sending fraudulent communications that appear to come from a reputable source like usually through email. The goal of phishing is to steal sensitive and important data like credit card and login information or to install malware on the victim’s machine or computers.
3. Man-in-the-middle (MitM)
Man-in-the-middle (MitM) attacks, is also known as eavesdropping attacks, occur when attackers insert themselves into a two-party transaction. Once the attackers interrupt the traffic, they can filter and steal data. Two common points of entry for MitM attacks are:
1. On unsecure public Wi-Fi, attackers can insert themselves between the network and a visitor’s device. Without knowing, the visitor passes all information through the attackers.
2. Once malware has breached a device, an attacker can install software to process all the victim’s information.
4. A Denial-of-Service
A denial-of-service attack floods servers and systems, or networks with traffic to exhaust resources and bandwidth. As a result, the system is unable to fulfill legitimate requests. Attackers can also use multiple compromised devices to launch this attack. This is known as a distributed-denial-of-service (DDoS) attack.
5. SQL Injection
A Structured Query Language (SQL) injection occurs when an attacker inserts malicious code into a server that uses SQL and forces the server to reveal information, it normally would not. An attacker could carry out a SQL injection simply by submitting malicious code into a vulnerable website search box.
6. DNS Tunneling
Over port 53, DNS tunneling utilizes the DNS protocol to communicate non-DNS traffic. Over DNS, it sends HTTP and other protocol traffic. Various, legitimate reasons to utilize DNS tunneling. However, to use DNS Tunneling VPN services, there are also malicious reasons. As a DNS, they can be used to disguise outbound traffic, concealing data that is typically shared through an internet connection. For malicious use, from a compromised system to the attacker’s infrastructure, DNS requests are manipulated to exfiltrate data. To a compromised system, it can also be used for command and control callbacks from the attacker’s infrastructure.
7. Zero-Day Exploit
A zero-day exploit, before a patch or solution is implemented, hits after a network vulnerability is announced. Attackers target the disclosed vulnerability during this window of time. Zero-day vulnerability threat detection requires constant awareness.
