Major Vulnerabilities That Hackers Are Targeting

Major Vulnerabilities That Hackers Are Targeting

Hackers are constantly on the lookout for vulnerabilities in IT services. These vulnerabilities are exploited because many organizations favor reaction to prevention. Your IT architecture will witness various changes- new applications, replaced IT members, and a new website. However, despite these changes, business continuity remains paramount. This is why it is necessary to take care of your cybersecurity space.  

A cyber intelligence agency in Canada reports that cybercriminals are exploiting several patched vulnerabilities. These vulnerabilities have been evident since 2017. The report maintains that the continued exploitation of vulnerabilities by hackers is due to the inability of many organizations to patch software appropriately.

Here are five major vulnerabilities that hackers are targeting to use against your organization. You should be aware of these so you can ensure your company isn’t at risk.

1. Vulnerability in Atlassian Confluence Server and Data Center

In recent times, a vulnerability was discovered in Atlassian Confluence Server. Confluence is a tool that enables people to collaborate and effectively share knowledge. If this vulnerability is successfully exploited, it will permit remote code execution within the account that controls the Atlassian confluence server.

If the service account is easy to manipulate, the hacker will have access to view, modify or even delete data. However, if the service account settings only permit fewer people to access the account, the effect of the exploitation of this vulnerability will be less severe. 

This vulnerability affects all supported versions of the confluence server and the confluence data server. 

2. Follina vulnerability in Microsoft support

The cybersecurity and infrastructure security agency (CISA) has released an official statement encouraging administrators to review a useful guide on the Follina vulnerability that negatively impacts Microsoft diagnostic tools. 

The vulnerability can easily allow any remote authorized user to gain complete control of a system and manipulate downloaded Microsoft documents. Thus, when a computer user downloads any malicious content, it grants ease to hackers to gain remote code execution.

To this effect, any hacker that successfully exploits this vulnerability will have the power to install any program, go through it, create accounts and even delete any data while exercising the user’s rights. 

3. Vulnerability in Cisco iOS

A significant number of Cisco routers that are running on iOS versions 12.0 and 12.1 are vulnerable to hackers’ activities. Vulnerability in Cisco will grant access to an unauthorized user to collect necessary information from any affected device. 

This vulnerability is enabled by enforcing administrative privileges on sensitive data. Hackers take advantage of this vulnerability by sending several HTTP requests to an affected device. The activities of the hacker can cause a denial of service. If the hacker is successful, it can cause the device to reload, leading to a denial of service. 

4. Vulnerability in Apache Log4j2

Apache develops Log4j. It is used to perform numerous functions in many applications, and it is also very dependable. Some of the services where it is relevant include enterprise applications and cloud services

The Log4j library is essential and has contributed to developing many notable Apache frameworks. But, in December 2021, several vulnerabilities were discovered in Log4j. These vulnerabilities permitted remote code execution and could also allow for disclosure of data if successfully exploited.

They can also affect applications when a function uses untrusted data input and transmits it to a vulnerable system version.

5. ProxyShell Vulnerabilities

ProxyShell is a popular attack chain that manipulates three vulnerabilities in Microsoft. If these vulnerabilities are successfully exploited, the hackers gain access to perform remote code execution. 

Microsoft has termed this vulnerability to be very critical. This implies that hackers can bring a lot of damage to an organization’s data when they exploit the manipulation. To successfully carry out their aims, hackers use two different methods. Such as:

  • Hackers establish web shells. This means that a command line interface can be easily created to affect a vulnerable system. A typical web shell that hackers use is the exchange mailbox. The hacker uses this by establishing a draft that contains a file within the exchange mailbox.
  • Hackers plant ransomware using proxy tools. The malware introduced by the hacker creates malicious responses to authentic emails. Interestingly, these malware attacks are not a product of the actions of a user who clicks on something that is not proper.
