Last Updated :
17 Jul, 2024
Clampi Virus is a Trojan virus, like many banking trojans, has evolved in its behavior and techniques over time. It takes control of browser settings without the user's knowledge or agreement, redirects the browser to malicious websites, or disables security settings. Windows PCs can be affected by the Clampi virus when a user clicks on a corrupted Web page, even if it appears legitimate and has been hacked.
What is the Clampi Virus?
The Clampi Virus (klaempʹee vīʹrəs) is a man-in-the-browser Trojan that steals login credentials and primarily targets banking and financial information. This Trojan, first discovered in the mid-2000s, is frequently concealed in trusted websites. It became a severe threat in 2009 and still lurks deep within computer systems today. The Trojan is specifically designed to target Microsoft operating systems. Another form of Clampi is used to steal money by using scareware as a scam technique. Clampi poses as a virus removal service in this situation and informs you that your machine is infected. The website encourages you to buy and download software to repair your computer.
Clampi's Rebirth
Clampi, like many banking trojans, has evolved in its behavior and techniques over time. Today, it takes control of browser settings without the user's knowledge or agreement, redirecting the browser to malicious websites or disabling security settings.
It disables your firewall's functionality, slows down your computer and internet connection, and changes the registry. Like the original Clampi, it takes information from you and sends it to hackers via remote servers.
How Does the Clampi Virus Work?
- Once downloaded to your computer, Clampi (also known as Ligats and Ilomo) awaits you to sign in to complete a financial transaction, such as accessing online banking or inputting credit card information for an online purchase.
- The virus is clever enough to hide behind firewalls and remain undiscovered for an extended period.
- Cybercriminals use an open-back channel to connect with malware via Control and Command servers.
- As you enter your username and password, Clampi saves this information and delivers it to the crooks who manage the virus.
- Clampi does not spread by itself but instead downloads a module that spreads it over network shares. The module is a dropper for PsExec, a tool for copying and executing processes on remote shares. The module drops two files.
- psexec.exe is a command-line program for executing processes locally or remotely, located in the %Temp% folder.
- The %Windir% folder contains psexesvc.exe, a wrapper for Service Manager.
How Clampi Virus Target Companies' Financial Accounts?
- Clampi virus is like racing to contain a rapidly spreading computer virus that targets financial accounts used by organizations worldwide.
- Clampi has been found to infect PCs through drive-by downloads.
- Users visit a website that has been hacked with an exploit that allows arbitrary executables to be silently installed on the computer.
- Anti-virus software can detect and stop Clampi, but the attackers are skilled at altering it so that it passes through, according to Stewart.
- Clampi is one of over a dozen "banking Trojans" that target online financial transactions.
How to Minimize the Effects of Clampi Computer Virus Attacks?
- Regular software update: Hackers can look for vulnerabilities, unpatched security flaws, and out-of-date systems. As a result, a defective computer is a perfect target for these hackers as such systems contain several security flaws that they can exploit to access your system and steal your data.
- Improve Network Security: While the Clampi virus does not work outside of Windows, other digital dangers may, and authentication software will be ineffective because hackers can gain access to your other devices, such as phones.
- Clean and Isolate Systems: The majority of Windows users do not clean their computers regularly. Once they have installed the operating system, such users continue to add applications, making it extremely difficult to keep track of which apps perform what.
How to Detect and Remove the Clampi Virus?
- Install antivirus or antimalware software: It can seem obvious, but many home PCs lack this safeguard. It's critical to maintain your PC virus-free. To get away from Clampi Virus, you need to install a good antivirus for your PC.
- Email attachments: Email attachments can be harmful as Cybercriminals seeking to propagate a virus may resort to sending spam emails containing a virus concealed in an attachment.
- Protect your network: Many personal computers use Wi-Fi to connect to files, printers, and the Internet. You have to ensure the network requires a secure password and avoid browsing on open networks.
- Run antivirus scans regularly: This might go without saying, but we frequently forget to do it. Change the settings so that scans occur at regular intervals (such as once a week). Using the smartphone when the antivirus software is active can be difficult. Try running it at night while the computer is dormant.
Malicious Effects of the Clampi Virus
- The Clampi virus enters your Windows computer and waits for your input, primarily looking for financial information.
- It hides deep within the computer system, waiting for you to sign onto an e-banking website or make an online transaction that requires you to enter your credit or debit card information, including the expiration date and CVV.
- The virus is well-equipped to distinguish financial information from the myriad of other words and messages you enter or transmit.
- It then logs your private data as soon as you input your username and password, transmitting it to the hackers who originally infected your computer via the trojan's control and command servers and multiple open backchannels.
