Techniques used by Plurox virus to infiltrate the system

As mentioned earlier, Plurox virus is capable to spread on its own to the same local network. It means – one infected system is enough to infect every connected system on the local network. Apart from this, developers use spam campaigns to infiltrate your system by malicious Plurox malware. An e-mail is send with catchy subject line to trick the users into believing that the e-mail is legitimate. As soon as the user opens the attached file in the e-mail, their system is exposed to the destructive Plurox Trojan.

Another deceptive method used is bundling. Hackers, hide the malicious files in the ‘Advanced Setting’ in installation process of regular software. Users generally rush through these steps and end up getting their computer infected with malware or ransomware.

Hence, beware of the suspicious e-mails and file attachments. Furthermore, never rush the installation process while downloading any software/application. The careless behavior of the users is the biggest reason for the attack of the malicious malwares.

 

Threat behavior

The SMB and UPnP plugins, which is used by Plurox to proliferate itself, gives it dangerous wormable capabilities. It then quickly exploits the vulnerabilities after getting initial hold into the network. The SMB plugin used is similar to the one used in Trickster malware. Hence, it is expected that the creators of Plurox and Trickster malwares may be linked.

It is of no surprise that, the malicious plugin used by Plurox is identical to the NSA – leaked EternalBlue exploit. The actual code is not used, instead they created their own version. Currently, the port used by Plurox gang to gain the initial hold on the network is still unknown.

To conclude with, we advise you to be careful with the suspicious e-mail attachments or links. Avoid using questionable sources to download applications/software. On the top of it, have a reputable antivirus installed and scan your system regularly.
