WordPress vulnerability allows attacker to gain full remote access of server
On February 19, 2019 security researchers at RIPS Technologies found a vulnerability in WordPress that allowed an attacker who had author privileges to execute arbitrary hypertext preprocessor (PHP) code to gain full remote access of the server.
What is WordPress?
WordPress is a free service/software that allows a user to host a website. Currently, it has over 33% market share in the context of content managers–services that allow users to manage content on a website.
The Vulnerability
The vulnerability exists through the exploitation of a Path Traversal and Local File Inclusion vulnerability. To understand the exploitation, there must be discussion about the image management of WordPress.
Impact
The vulnerability has been present in WordPress for over 6 years. While there are no reports of the vulnerability being exploited, the possible impact is wide. By controlling a WordPress site, a malicious person could alter existing links and references to identical spoofed sites as a phishing attack for credentials.
Mitigation
Current versions of WordPress, 4.9.9 and 5.0.1 have implemented patches to the vulnerability found by RIPS Technologies. If possible, update your WordPress to the latest version. If this is not possible, scrutinize the accounts who have author permissions to the WordPress page.

How are Remote Access Trojans Useful to Hackers?
Attackers using remote control malware cut power to 80,000 people by remotely accessing a computer authenticated into SCADA (supervisor y control and data acquisition) machines that controlled the country’s utility infrastructure. RAT software made it possible for the attacker to access sensitive resources through bypassing the authenticated user's elevated privileges on the network. Having access to critical machines that control city resources and infrastructure is one of the biggest dangers of RAT malware.
Why do attackers use RATs?
RATs have the same remote-control functionality as RDPs, but are used for malicious purposes. Attackers always code software to avoid detection, but attackers who use a RAT risk being caught when the user is in front of the device and the mouse moves across the screen. Therefore, RAT authors must create a hidden program and use it when the user is not in front of the device. To avoid detection, a RAT author will hide the program from view in Task Manager, a Windows tool that lists all the programs and processes running in memory. Attackers aim to stay hidden from detection because it gives them more time to extract data and explore network resources for critical components that could be used in future attacks.
What happens if you don't see malware in Task Manager?
If you don’t see any potential malware in Task Manager, you could still have a RAT that an author programmed to avoid detection. Good anti-malware applications detect most of the common RATs in the wild. Any zero-day malware remains undetected until the user updates their anti-malware software, so it’s important to keep your anti-malware and antivirus software updated. Vendors for these programs publish updates frequently as new malware is found in the wild.
What is remote control software?
Legitimate remote-control software exists to enable an administrator to control a device remotely. For example, administrators use Remote Desktop Protocol (RDP) configured on a Windows server to remotely manage a system physically located at another site such as a data center. Physical access to the data center isn’t available to administrators, so RDP gives them access to configure the server and manage it for corporate productivity.
What happens if you remove the internet from your computer?
Removing the Internet connection from the device disables remote access to your system by an attacker. After the device can no longer connect to the Internet, use your installed anti-malware program to remove it from local storage and memory. Unless you have monitoring configured on your computer, you won't know which data and files transferred to an attacker. You should always change passwords across all accounts, especially financial accounts, after removing malware from your system.
Can malware writers name processes?
For most applications and processes, you can identify any suspicious content in this window, but malware writers name processes to make them look official. If you find any suspicious executables and processes, search online to determine if the process could be a RAT or other type of malware.

The best defense is to keep your users educated. Once you’ve educated your users, take precautions in ways that protect your network without interfering with their productivity. Antivirus software and firewalls are just a given in any network design, but you have several other options available to you.

What is an attack surface?
Wired defines an attack surface as the total number of points or vectors through which an attacker can try to enter an environment or network. In terms of cybersecurity, this means how a bad actor could gain access to your network to either send, extract, or encrypt data through the holes they find in a network. TechTarget adds that every network interaction point allows for a potential network attack surface. In other words, an attack on a surface occurs when bad actors are able to find holes in a network which then allows them to cause disruption. This disruption can come in the forms of data breaches, ransomware, and more.
What was the most notable ransomware attack?
One of the most notable ransomware attacks was the infamous City of Atlanta fiasco. According to Data Breach Today, whoever attacked Atlanta gained access to their system through a surface that led them to getting a hold of administration credentials. From there, the attacker was able to spread malware onto a server. In the Data Breach Today article, information security researcher Kevin Beaumont notes that Atlanta left RDP port 3389 and block port 445 open to the Internet.
