While this is recognized as an older kit, it resurfaced in Magnitude targets select Asian countries and delivers a specific payload. It has been around for a long time, but has changed its form. It used to include exploits for Flash Player but has been adapted to solely attack Internet Explorer vulnerabilities. The Magnitude EK version targets South Korea by checking IP address and language, among other things and delivers a special ransomware called Magniber. They would use a control panel in which they could upload malware and track their results.
Considering the attackers are using known vulnerabilities, you may wonder how these weaknesses remain exposed, allowing attacks to be successful. Oftentimes, due to the volume of vulnerabilities and the competing priority of keeping the network available, they need to make practical tradeoffs by assigning importance to certain vulnerabilities and leaving open patches to other vulnerabilities to a later time. Essentially, there is simply too much to fix all in one go.
They have to prioritize which updates need to happen first and hope that they make the right decisions, as cybercriminals wait to take advantage of every weakness. A couple of other factors lend to the success of exploit kits, one being that initial contact is easily made, for example, by someone clicking on a rogue advertisement or a link in an email.

Description : This is an Adobe Flash Player buffer overflow vulnerability that allows remote attackers to execute arbitrary code via unknown vectors.
Affected software : Adobe Flash Player before Description : This is an Adobe Flash Player memory corruption vulnerability that allows an attacker to execute arbitrary code in the context of the user running the affected application. Failed exploit attempts will likely result in denial-of-service conditions. Related attacks : Attack on compromised US-based ad network. Description : This is an Adobe Flash Player buffer overflow vulnerability that occurs when parsing a compiled shader in a Flash object.
It allows attackers to run some processes and run an arbitrary shellcode. Related attacks: Malicious YouTube ads. Description : This is an Adobe Flash Player remote integer overflow vulnerability that allows attackers to execute arbitrary code via unspecified vectors.
Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support. Exploits take advantage of vulnerabilities in software. A vulnerability is like a hole in your software that malware can use to get onto your device. Malware exploits these vulnerabilities to bypass your computer's security safeguards to infect your device.
Exploits are often the first part of a larger attack. Hackers scan for outdated systems that contain critical vulnerabilities, which they then exploit by deploying targeted malware.
Exploits often include shellcode, which is a small malware payload used to download additional malware from attacker-controlled networks. Shellcode allows hackers to infect devices and infiltrate organizations. Exploit kits are more comprehensive tools that contain a collection of exploits.
The compromised page will discreetly divert web traffic to another landing page. If the device is fully patched and up-to-date, the exploit kit traffic will cease. If there are any vulnerabilities, the compromised website discreetly diverts network traffic to the exploit.
The exploit uses a vulnerable application to secretly run malware on a host. If and when an exploit is successful, the exploit kit sends a payload to infect the host. The payload can be a file downloader that retrieves other malware or the intended malware itself. While the most common payload is ransomware, there are many others, including botnet malware, information stealers and banking Trojans. A recent example of this is the utilization of the Neutrino exploit kit to deliver Locky ransomware in the Afraidgate campaign.
Pages from the compromised site contain an injected script that redirects visitors to the Afraidgate domain.
