7zip and its vulnerabilities

Although 7zip itself is not a virus, the software application does have some vulnerabilities, especially in its older versions. Some of its vulnerabilities include: 

  • 7zip does not have ALSR protection on Windows. ASLR (Address Space Layout Randomization) is a mechanism to protect your computer memory against buffer overflow attacks.  
  • Also, the DEP (Data Execution Prevention) protection feature of Windows that protects software from malicious code for 7zip is only enabled in 64-bit Windows 7 and 32-bit Windows 10 systems. 

The newer versions after 2018 have mitigated the vulnerabilities to a large extent. So, you must always try to use the latest version of 7zip on your system. 

7zip and its encryptions

7zip uses encryption software to encrypt your files so that they remain secure during email transfers or memory transfers. 

The tool uses 256- bit AES encryption to protect its files. The 256 bit is the most advanced form of AES encryption. So, you can rest assured when trying to compress or extract files with 7zip.

7zip and viruses

The primary possibility of getting a virus from 7zip is through the executable file in the 7zip archive. When you receive a 7zip archive file from an untrusted source, you should not open it quickly as the file may be infected with malicious code. So, make sure that the executable file is from a trusted source before opening it. 

Another possibility of a 7zip file and virus is when hackers or spammers rename their file containing viruses as “7zip” and load them into your system. So, only download the 7zip file from a trustworthy source to avoid viruses on your system. 

Having an antivirus like Avast or the default Windows Defender will help you scan your system for viruses, remove them, and prevent any malicious software from entering your computer through the network by ensuring strong firewall protection.
