Removal instructions for the StripedFly malware

Also Known As: StripedFly malware framework
Type: Trojan
Damage level: Severe

What kind of malware is StripedFly?

StripedFly is a sophisticated cross-platform malware framework. It targets Windows and Linux operating systems. This software is modular, i.e., it downloads modules for additional functionality.

StripedFly utilizes extensive anti-detection capabilities that have contributed to its initial misidentification as a cryptocurrency miner. While this malware does have cryptominer abilities, its functionalities are far broader.

StripedFly first came into prominence in 2022; however, its use of an exploit known since 2017 suggests that this program might have been around for quite a lot longer.

It is noteworthy that StripedFly uses legitimate code repositories to host and retrieve content, e.g., Bitbucket, GitHub, and GitLab. Download tracking provided by Bitbucket indicated that certain files associated with this malware were downloaded in the 50-150 thousand range. The numbers from this repository alone show that StripedFly has had a wide outreach.

StripedFly malware overview

As mentioned in the introduction, StripedFly is considered to be a high-end malware due to the multitude of implemented anti-detection capabilities. This malware framework infiltrates systems in a multi-stage chain, which includes a custom-built lightweight TOR client.

StripedFly is a modular software, and as such – its infections could vary based on the combination of modules downloaded.

To elaborate on some of the noteworthy components, this framework uses a module for reconnaissance. It gathers system data and sends it back to the C&C (Command and Control) server, e.g., device name, OS version, MAC address, RAM, NetBIOS name, IP addresses (geolocations), user account name and privileges, system language and keyboard layout, installed anti-viruses, etc.

StripedFly also uses several modules to receive and execute commands successfully. Other modules give this malware the ability to find and download specific format files, such as those relating to source code, certificates, databases, archives, documents, images, audio, video, etc. StripedFly forgoes system folders but scans for files of interest in all local drives and network shares.

Additionally, the malware can gather information about active windows, and it can take screenshots. StripedFly likewise records audio via integrated/attached microphones.

Another module is used to steal credentials. It collects usernames/passwords, personally identifiable details (e.g., names, addresses, occupations, job titles, employing companies, etc.), and other credentials.

Targeted browsers include (but are not limited to) Google Chrome, Mozilla Firefox, Internet Explorer, Brave, Epic Privacy Browser, Nichrome, RockMelt, SeaMonkey, and Vivaldi. This module also gathers Wi-Fi network names and FTP, SSH, and WebDAV data for Cyberduck, FileZilla, WinSCP, and similar software.

StripedFly's cryptocurrency mining module had first led researchers to misidentify this malware as a cryptominer. This malware mines (i.e., generates) Monero cryptocurrency.

It is unclear whether this module's inclusion or retention is limited to direct financial motivations, as cryptomining is not an incredibly lucrative avenue – especially not for developers of sophisticated malware.

It is pertinent to mention that modular malware infections can differ depending on their configuration (i.e., installed modules), and malicious software developers often improve upon their creations. Furthermore, StripedFly is capable of retrieving updates; hence, potential future iterations of this malware could boast additional/different capabilities or features.

To summarize, the presence of software like StripedFly on devices can lead to decreased system performance, severe privacy issues, financial losses, and even identity theft.

Malware framework examples

We have investigated countless malicious program samples; MgBotSoul, and NetDooka are just a couple examples of malware frameworks.

It must be stressed that regardless of whether a malicious program has limited abilities and incredibly specific uses or a wide variety of functionalities with a broad application – the presence of this software on a system threatens device integrity and user safety. Therefore, it is paramount to eliminate all threats immediately upon detection.

How did StripedFly infiltrate my computer?

How StripedFly is proliferated is currently unknown. However, this malware is capable of self-spreading through local networks.

Generally, phishing and social engineering tactics are prevalent in malware distribution. Malicious software is typically disguised as or bundled with ordinary program/media files. They can be archives (ZIP, RAR, etc.), executables (.exe, .run, etc.), documents (Microsoft Office, Microsoft OneNote, PDF, etc.), JavaScript, and so forth.

The most widely used distribution methods include: drive-by (stealthy/deceptive) downloads, untrustworthy download sources (e.g., freeware and free file-hosting websites, Peer-to-Peer sharing networks, etc.), malicious attachments or links in spam emails/messages, online scams, malvertising, illegal software activation ("cracking") tools, and fake updates.

Aside from self-proliferating via local networks, some malicious programs can spread through removable storage devices (e.g., external hard drives, USB flash drives, etc.).

How to avoid installation of malware?

It is crucial to exercise caution when browsing since fraudulent and malicious online contact usually appears genuine and innocuous. Attachments or links found in suspicious/irrelevant mail (e.g., emails, PMs/DMs, SMSes, etc.) must not be opened, as they can be infectious.

Furthermore, all downloads must be performed from official and verified channels. Another recommendation is to activate and update software by using legitimate functions/tools, as those obtained from third-parties may contain malware.

We must emphasize the importance of having a reputable anti-virus installed and kept updated. Security programs must be used to run regular system scans and to remove threats and issues. 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.

Refresh Autoruns application results

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.
