How to remove Latrodectus malware from the operating system

Also Known As: Latrodectus malware loader
Type: Trojan
Damage level: Severe

What kind of malware is Latrodectus?

Latrodectus is a type of malware categorized as a loader. Loaders are a class of malicious software designed to infiltrate a target system and execute additional payloads. Once infiltrated, Latrodectus acts as a gateway for more harmful malware to be deployed onto the infected system, thereby exacerbating the potential damage and threat to the victim's privacy and security.

More about Latrodectus

Latrodectus, a loader malware, is capable of executing various types of malicious payloads, including ransomware, Remote Access Trojans (RATs), banking Trojans, information stealers, keyloggers, and other forms of malware. It is known that one of the payloads distributed via Latrodectus is a stealer called Lumma.

Ransomware encrypts data on the victim's system and demands payment for the decryption key, effectively barring users from accessing their own files until the ransom is paid. RATs grant cybercriminals access to infected systems, enabling them to remotely manipulate the victim's computer, pilfer sensitive information, or execute malicious actions without the user's awareness or consent.

Banking Trojans target sensitive financial information, including login credentials and credit card details, on victims' devices. Designed to steal such data, they pose a significant risk to users' financial security and privacy.

Information stealers are designed to clandestinely collect and exfiltrate sensitive information from infected systems, including login credentials, personal documents, and browsing history. They can compromise users' privacy and facilitate identity theft or other forms of cybercrime.

Keyloggers secretly record and log all keystrokes entered by the user, including usernames, passwords, and other sensitive information. They can covertly capture valuable data without the user's knowledge, posing a significant threat to privacy and security.

How did Latrodectus infiltrate my computer?

Latrodectus is commonly distributed through phishing emails, which deceive recipients into visiting websites hosting the malware. These emails often employ social engineering tactics to lure users into clicking on malicious links or downloading infected attachments.

One known example of how the malware is distributed involves a chain of interconnected steps. It starts with a website's contact form email containing a link leading to a counterfeit Azure login page. Once the page is accessed, a JavaScript (JS) file is automatically downloaded onto the user's device.

The JS file then retrieves an installer MSI, which, upon execution, implants a Latrodectus Dynamic Link Library (DLL) onto the system. This DLL is configured for persistence, ensuring its continued presence even after system reboots. Finally, the Latrodectus malware establishes communication with its command-and-control (C2) server, allowing malicious actors remote access to the infected device.

How to avoid installation of malware?

Exercise caution when dealing with unsolicited emails, particularly those containing suspicious links or attachments. Opt for official sources when downloading software and files, avoiding peer-to-peer networks, third-party downloaders, or unofficial websites.

Do not interact with pop-ups, ads, and links (or buttons) while visiting shady pages. Ensure that all your programs, including your operating system, are regularly updated. Additionally, maintain proactive protection by conducting routine malware scans using reliable antivirus software to detect and remove any threats.

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.

manual malware removal step 5Check the list provided by the Autoruns application and locate the malware file that you want to eliminate.

You should write down its full path and name. Note that some malware hides process names under legitimate Windows process names. At this stage, it is very important to avoid removing system files. After you locate the suspicious program you wish to remove, right click your mouse over its name and choose "Delete".

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. Be sure to enable hidden files and folders before proceeding. If you find the filename of the malware, be sure to remove it.

Search for malware and delete it

Reboot your computer in normal mode. Following these steps should remove any malware from your computer. Note that manual threat removal requires advanced computer skills. If you do not have these skills, leave malware removal to antivirus and anti-malware programs.

These steps might not work with advanced malware infections. As always it is best to prevent infection than try to remove malware later. 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.
