There are 7 key strategies we recommend to use to protect a Small and Medium Business or organization from cyber attacks. Cyber attacks can target individuals, groups, organizations, or governments. The intent might be to inflict reputational damage or harm to a business or person, or theft of valuable data. Intellectual property (IP) theft or unauthorized accessĪ cyber attack happens when cybercriminals try to gain illegal access to electronic data stored on a computer or a network.Private and public Web browser exploitsv.Denial-of-service and distributed denial-of-service attacks.Stolen hardware, such as laptops or mobile devices.Malware, phishing, spamming, spoofing, spyware, trojans and viruses.Here are some examples of common cyber attacks and types of data breaches: It can also be used for command and control callbacks from the attacker’s infrastructure to a compromised system. For malicious use, DNS requests are manipulated to exfiltrate data from a compromised system to the attacker’s infrastructure. They can be used to disguise outbound traffic as DNS, concealing data that is typically shared through an internet connection. However, there are also malicious reasons to use DNS Tunneling VPN services. ![]() There are various, legitimate reasons to utilize DNS tunneling. It sends HTTP and other protocol traffic over DNS. DNS TunnelingĭNS tunneling utilizes the DNS protocol to communicate non-DNS traffic over port 53. Zero-day vulnerability threat detection requires constant awareness. Attackers target the disclosed vulnerability during this window of time. Zero-day exploitĪ zero-day exploit hits after a network vulnerability is announced but before a patch or solution is implemented. An attacker could carry out a SQL injection simply by submitting malicious code into a vulnerable website search box. ![]() SQL injectionĪ Structured Query Language (SQL) injection happens when an attacker inserts malicious code into a server that uses SQL and forces the server to reveal information it normally would not. This is known as a distributed-denial-of-service (DDoS) attack. Attackers also use multiple compromised devices to launch this attack. That makes the system incapable to fulfill legitimate requests. Once malware has breached a device an attacker can install software to process all of the victim’s information.Ī denial-of-service attack fills systems, servers, or networks with traffic that exhaust resources and bandwidth.Without knowing, the visitor passes all information through the attacker. On unsecure public Wi-Fi, attackers can insert themselves between a visitor’s device and the network. ![]() Two common points of entry for MitM attacks: Once the attackers interrupt the traffic, they can filter and steal data. Man-in-the-middle (MitM) attacks, also called eavesdropping attacks, occur when attackers insert themselves into a two-party transaction. Phishing is an increasingly common cyberthreat. The goal is to steal or get sensitive data like credit card and login information or to install malware on the victim’s machine. Phishing is the method of sending fraudulent communications that seems to come from a reputable source, usually through email. ![]() Malware breaches a network through a vulnerability, typically when a user clicks a dangerous link or email attachment that then installs risky software. Malware is a term that describes malicious software, including spyware, ransomware, viruses, and worms. Cybercriminals use different methods to launch a cyber attack that includes malware, phishing, ransomware, man-in-the-middle attack, or other methods. A cyber attack is an attempt to disable computers, steal data, or use a breached computer system to launch additional attacks.
