An attacker is reportedly injecting malware into infected devices using popular VPN applications to gain remote control of the devices they are attacking. Google's Managed Defense team reported this disturbing finding, which sheds light on how malicious actors use SEO poisoning tactics to spread what is known as Playfulghost.

It has become increasingly important for individuals who prioritize the protection of their personal data and online privacy to use virtual private networks (VPNs). VPNs establish a secure, encrypted connection between users' devices and the internet, protecting their IP addresses and online activity against prying eyes. 

However, it should be noted that not all VPN applications are trustworthy. The number of fake VPN apps being distributed under the guise of legitimate services is increasing, stealing the sensitive information of unsuspecting users. Researchers have discovered that during the third quarter of 2024, fake VPN applications have become increasingly widespread globally, which is a worrying trend. In comparison to the second quarter, security analysts have reported a 2.5-fold increase in user encounters with fraudulent VPN apps.

These apps were either infected with malware or were built in such a way that they could be exploited by malicious actors. As a result of this alarming development, it is critical to be vigilant when choosing VPN services. Users should take precautionary measures when choosing VPN services and ensure that the apps they download are legitimate before downloading to safeguard their data and devices. 

As more and more home users turn to virtual private networks (VPNs) as a means to safeguard their privacy, to ensure their internet activity is secure, and to circumvent regional content blocks, these VPNs are becoming increasingly popular. Scammers and hackers are aware that the popularity of VPNs is growing, and so they intend to take advantage of that trend as much as possible. 

As an example, recently it has been found that some VPNs have been found to have security vulnerabilities that do not make them as secure as they should be. Playfulghost is a backdoor similar to Gh0st RAT, a remote administration tool that is well-known in the security community. According to Google's expert, Playfulghost is "a backdoor that shares functionality with Gh0st RAT." The latter has been around since 2008, and it is considered one of the best. 

The traffic patterns of Playfulghost can be distinguished from those of other known threats, especially in terms of encryption and traffic patterns. There are several ways hackers use phishing and SEO poisoning to trick their victims into downloading malicious software onto their computers, and according to a Google expert, one victim was tricked into opening a malicious image file for Playfulghost to run remotely from a remote location, which results in the malware being downloaded onto his computer. In the same vein, SEO poisoning techniques employed trojanized virtual private network (VPN) apps to download Playfulghost components from a remote server on the victims' devices (see GIF below). 

Infected with Payfulghost, an attacker can remotely execute a wide range of tasks on the device once it has been infected. It is particularly dangerous as a virus. Data mining is capable of capturing keystrokes, screenshots, and audio, as well as capturing screenshots. In addition to this, attackers can also perform file management activities, including opening, deleting, and writing new files. Security experts from Google have warned that a new malware threat has been detected that is very dangerous. It is known as Playfulghost and is distributed worldwide via fraudulent VPN apps. Researchers have warned that this scam uses sophisticated techniques to trick users into downloading infected VPN software, including what is called "SEO poisoning". 

There is something especially cruel about this latest cyberattack because signing up for one of the best VPN deals is usually an easy way to improve users' level of privacy and security online. Unfortunately, those who installed the fake VPN applications laced with malware in the last few days have now found themselves in the worst possible position due to the malware they have installed. As people know, the purpose of Playfulghost is to allow hackers to monitor every letter users type on their keyboard, a practice known as keylogging. 

It can also record audio from the built-in microphone on users' computers, laptops, tablets, or desktops, and it can also be used as a tool to record what they are seeing on the screen, which is often used for blackmail. The dangerous malware also enables attackers to remotely execute various file management activities, including opening, deleting, and writing new files, This can enable hackers to download and install other types of malware on machines infected with Playfulghost. Playfulghost also makes it possible for attackers to perform various file management activities remotely, such as opening, deleting, and creating files, allowing hackers to download and install other kinds of malware on computers infected with this dangerous malware. 

As it turns out, Playfulghost's functionality is quite similar to Gh0st RAT, which has wreaked havoc on PCs since 2001 and is now a public open-source tool, whose source code was released in 2008. Since this code is widely available, there have been several copies and clones created, including the latest variant. In addition to utilizing distinct traffic patterns and encryption, Google security researchers have pinpointed two methods by which the malware is being spread by hackers, according to their study. The first is using the infected computers' network cables and the second is via the Internet. 

 The first thing to know is that cybercriminals are utilizing phishing emails — unsolicited messages that entice people to download malicious software. One of the earliest examples that was spotted by Google's team involved emails with themes such as "Code of Conduct" which trick users into downloading the attached file, which turned out to be Playfulghost, a nasty infection. 

Another documented case has also been found in which a victim was tricked into opening a malicious image file and when they opened it in the background Playfulghost was automatically installed and activated on their computer from a remote server. Secondly, the malware may also be spread by bundling it with popular VPN apps in a process known as SEO poisoning. This method has been gaining popularity recently among virus creators. Search engine poisoning is the act of manipulating or hacking a search engine to make malicious downloads appear as an official import.
