More about 44Caliber

Upon infiltration, 44Caliber covertly extracts a wide range of data stored within browsers, including browsing history, saved passwords, autofill data, cookies, and form inputs. This stolen information not only compromises the user's privacy but also exposes them to various forms of cyber threats, such as identity theft, financial fraud, and unauthorized access to online accounts.

In addition to its proficiency in pilfering browser data, 44Caliber exhibits a concerning capability to target cryptocurrency wallets, posing a grave threat to users' digital assets. Upon infection, the malware infiltrates the system and meticulously scans for traces of cryptocurrency wallets. Through sophisticated techniques, it extracts wallet files, private keys, and other sensitive information crucial for accessing and managing cryptocurrency funds.

The theft of crypto wallet data by 44Caliber opens the door to substantial financial losses and exposes victims to the risk of irreversible transactions and account hijacking. By compromising the security of cryptocurrency holdings, the malware enables threat actors to siphon funds from victims' wallets, manipulate transactions, and engage in fraudulent activities with impunity.

Furthermore, 44Caliber targets File Transfer Protocol (FTP) clients, extracting login credentials used for accessing remote servers and transferring files, potentially exposing sensitive corporate data to unauthorized access and manipulation. Additionally, the malware steals login credentials from Virtual Private Network (VPN) clients.

Moreover, 44Caliber demonstrates a concerning capability to target Discord session data, a popular communication platform widely used by individuals and organizations alike. By infiltrating Discord sessions, the malware can extract user login credentials, private messages, and other sensitive data exchanged within the platform.

This breach not only compromises user privacy but also poses a significant security risk, potentially enabling threat actors to impersonate users, disseminate malicious content, or gain unauthorized access to sensitive conversations and shared files.

It is crucial to note that 44Caliber might be able to access and steal additional data beyond what has been discussed. Furthermore, it is noteworthy that this information stealer is promoted under the guise of a free tool intended for educational purposes.

How did 44Caliber infiltrate my computer?

Cybercriminals employ deceptive tactics, such as disguising malicious shortcut files as innocent images like PNG or JPG files, to distribute 44Caliber. These shortcuts are crafted to download a nefarious executable file upon activation, facilitating the infiltration of systems by 44Caliber once the malicious executable is run.

Also, attackers often craft deceptive messages (emails) to trick recipients into opening malicious attachments or clicking on malicious links. Once the attachment is opened or the link is clicked, malware can be downloaded onto the victim's system. Another prevalent delivery method is malvertising, where attackers inject malicious code into online advertisements.

Simply visiting a compromised page can also be enough to trigger the malware download. Furthermore, threat actors may leverage exploit kits, which are bundles of prepackaged exploits designed to target specific vulnerabilities in software or operating systems. In other cases, computers can be infected via pirated software, downloads from P2P networks, and other dubious sources.

How to avoid installation of malware?

Ensure that your operating system and software applications receive regular updates. Install trustworthy antivirus or anti-malware software on all your devices. Exercise caution with unsolicited emails, particularly those with attachments or links from unfamiliar or suspicious sources. Steer clear of visiting untrustworthy websites and engaging with pop-ups or advertisements on them.

Download software and files exclusively from reputable sources like official app stores or the developer's website. Refrain from downloading pirated or cracked software to minimize the risk of malware attacks.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Delete malware in Autoruns

After removing the malware through the Autoruns application (this ensures that the malware will not run automatically on the next system startup), you should search for the malware name on your computer.

To keep your computer safe, install the latest operating system updates and use antivirus software. To be sure your computer is free of malware infections, we recommend scanning it with Combo Cleaner Antivirus for Windows.
