PUA:Win32/PassShow is an unwanted program that attacks passwords on a computer and poses serious security risks. It undermines the security of private information, as passwords are often the entrance to personal and financial data. PUA:Win32/PassShow infection can lead to illegal access, allowing cyber criminals to access personal accounts, potentially resulting in identity theft or fraudulent financial transactions.

The exposure of passwords may stretch beyond individual accounts to impact linked systems, leading to a cascading effect of security breaches. As a result, the long-term effects may include social damage, financial losses, and the possibility of continued abuse of hacked accounts.

How does it infect the computer?

When computer users are careless on the internet, PUA:Win32/PassShow can infiltrate computers through various vectors. Clicking on malicious links in phishing emails or on dubious websites is a common method. These links may lead to drive-by downloads, where malware is automatically downloaded and installed on the user’s system without their knowledge or consent. Additionally, downloading files from untrusted sources, such as pirated software or suspicious attachments, can introduce PUA:Win32/PassShow or other malware onto the computer.

Another avenue for infiltration is through outdated software and operating systems. Cybercriminals often exploit known vulnerabilities in outdated software to gain unauthorized access. Neglecting software updates leaves these vulnerabilities open for exploitation. Social engineering tactics, like fake pop-ups or alerts, can also trick users into installing PUA:Win32/PassShow. For instance, a deceptive message may prompt the user to click on a link or download a file by posing as a legitimate system update or antivirus software.

How does this malware operate?

The payload of PUA:Win32/PassShow targeting passwords on a computer typically involves various malicious activities aimed at compromising sensitive information. Initially, this threat often incorporates keyloggers, which covertly record keystrokes, capturing usernames and passwords entered by the computer user. Additionally, PUA:Win32/PassShow may deploy credential-stealing techniques, such as intercepting login credentials transmitted over unsecured connections or exploiting vulnerabilities in authentication processes.

Furthermore, PUA:Win32/PassShow utilizes methods like screen scraping, where they capture and transmit screenshots of login pages to gather sensitive information visually. In more advanced cases, the payload may include the deployment of remote access tools, allowing cybercriminals to gain control of the infected system and directly extract stored passwords or manipulate user sessions. The overall objective is to surreptitiously harvest passwords and authentication data, enabling unauthorized access to personal accounts, financial information, and other confidential resources on the compromised computer.


A computer may show several signs if compromised by PUA:Win32/PassShow. Users may notice a major drop in system speed, as this threat often takes resources in the background. Moreover, unexpected pop-ups, ads, or browser changes may occur, interrupting normal online activities. Also, unexpected changes in system settings, such as a changed site or preferred search engine, may indicate unwanted tweaks by the program. Finally, the appearance of new, unknown software or toolbars, especially those claiming to improve the online browsing experience, can be a clear sign of a PUA:Win32/PassShow infection.

How to protect the computer from PUA:Win32/PassShow?

The initial defense that comes to mind for any computer user is to install an anti-virus or anti-malware program. This move is sensible and probably the most practical way to protect the computer against a PUA:Win32/PassShow attack. Hence, keep in mind that having security software does not guarantee full protection. The majority of the prevention still lies in being cautious of users, and therefore, we are providing the following information as guidelines to protect the computer from virus infection.

Avoid Malicious Websites

There are enormous numbers of websites that were made for the primary purpose of spreading PUA:Win32/PassShow. Normally, these sites are involved in integrating malicious pop-up and browser hijacker, that will eventually cause further virus infections. Avoid such websites.

Ignore and Delete Phishing Emails

The mass-mailing of computer viruses gives the attackers the luxury of spreading their malicious code in just one send-off. This will arrive in the inbox as an email that appears to be from a legitimate organization. So, if you receive an unexpected email with a link or an attached file, better delete it immediately.

Do Not Click a Suspicious Link

Links from social media, forums, and blog sites are sometimes being utilized by attackers to drive web users to a malicious page that contains malicious code. Therefore, do not just click on any link, especially if it looks suspicious. Accidental access to the destination site may lead to a PUA:Win32/PassShow infection.

Be Careful When Downloading Files

Cracked software, serial key generators, and several freeware are seen as another method that spreads the PUA:Win32/PassShow virus. Avoid acquiring these types of applications, and if there is a need to download freeware or shareware, be sure to obtain it from the official website or trusted providers.
