An exploit in computer security refers to a piece of code, software, or technique that takes advantage of vulnerabilities within a system, application, or network. Cybercriminals use exploits to perform unauthorized actions to intercept sensitive business data.
Types of exploits
Exploits come in a variety of forms that IT security professionals should be aware of.
-
Remote exploits
Remote exploits allow attackers to manipulate a system from afar.
-
Local exploits
Local exploits require physical access to the targeted endpoint device. Cybercriminals escalate user privileges or abuse systems internally, such as privilege escalation attacks.
-
Zero-day exploits
Zero-day exploits usually have lesser-known vulnerabilities unknown to the vendor or the public. Without available patches, attackers weaponize such loopholes to gain an advantage before they’re addressed.
-
Browser exploits
Browsers exploit target vulnerabilities within web browsers or plugins, such as Flash and Java, which are targeted to install malware or steal information.
-
Denial-of-Service (DoS) exploits
By abusing system vulnerabilities, DoS attack exploits make resources or services unreachable to legitimate users, causing disruptions.
What is an exploit kit?
An exploit kit is a pre-packaged set of tools used by hackers to streamline exploit-based cyberattacks. These kits often target specific vulnerabilities and automate the exploitation process, making cyberattacks more accessible to less-skilled attackers. Exploit kits are typically distributed through malicious websites or ads, tricking users into unintentionally initiating the attack process.
How to tell if there’s an exploit attack
Recognizing the symptoms of an exploit attack allows IT teams to resolve issues and safeguard data from unauthorized parties quickly.
Unusual network traffic
Sudden spikes or irregular patterns in network traffic mean that exploit attempts.
Unstable performance
Applications affected by an exploit attack often behave unpredictably, leading to error messages, restarts, or system crashes.
Suspicious files and modifications
Files that have been moved to unexpected locations or system files that enact sweeping modifications to system configurations could sometimes indicate an exploit attack.
How to protect devices from exploits
-
Consistent patch distribution
Software left unpatched is one of the most common exploit vectors. Organizations should invest in patch management software to ensure that their software always has the latest security patches installed. With NinjaOne’s patch management software, users can automate all the necessary tasks, from scanning items,
-
Vulnerability scanning
Regular scans help identify missing patches or patches that failed to install, allowing users to address the patching schedule before the exploit attack.
-
Security awareness training
Educating IT teams and organizations on common vectors for attack, such as phishing, and safe browsing practices helps reduce error-based exploits.
Deploying endpoint security to prevent exploits
Exploit attacks target weaknesses in software, systems, or processes, and the impact can range from data theft to complete operational shutdowns. IT experts can stay ahead with vulnerability management like NinjaOne.
With NinjaOne, you can protect all their Windows, macOS, Linux, Android, iOS, and iPadOS devices from any exploit attacks. NinjaOne centralizes IT operations with its all-in-one tools that consolidate RMM, vulnerability management, and endpoint security tools into a single, easy-to-use dashboard.
