Opportunistic attack

Opportunistic attack is a type of cyber attack against computers, networks, and other information systems that takes advantage of unintended gaps or weaknesses in computer security systems to maliciously breach or access data within a system. Opportunistic attacks often involve techniques such as exploiting misconfigurations, taking advantage of poor security practices, and utilizing available loophole or vulnerabilities.

Opportunistic attacks are an attractive avenue for enemies attempting to gain access to a computer systems because it can be done with ease and without detection. Attackers can take advantage of the vulnerabilities left by existing processes, systems, and procedures. During an opportunistic attack, the attacker leverages the gaps or weaknesses in a system by exploiting them to gain unauthorized access to data or other information within the system. This type of attack is most frequently seen in targeted attacks where attackers are searching for data that can give them an advantage in some way, either in the form of financial gain, or simply by gaining access to private information.

There are various methods used in opportunistic attacks. These can range from exploiting improper permissions to exploiting misconfigurations in servers or software to looking for weak passwords or other authentication credentials. Other methods include exploiting software or system vulnerabilities, cross-site scripting, malicious websites, and unsecured network connections. Attacks are usually launched remotely as well using automated tools and scripts to collect data from different systems.

The best way to ensure that an opportunistic attack cannot be used against a system is to ensure securely configured hardware, software, and policies. It is also important to regularly patch and update systems and software, ensure that strong passwords are set, and that systems are regularly scanned for malicious activity.
