What kind of malware is PureLogs?

Cybercriminals use malware of this type to steal sensitive data that can be monetized in one way or another. Typically, information-stealing malware runs silently in the background.

More about PureLogs

Threat actors use information stealers to obtain various types of data. They steal information from web browsers, installed apps (e.g., FTP and VPN clients, messengers, email clients, password managers), operating system, cryptocurrency wallets, and so forth. Also, they can be used to take capture screenshots.

The stealer possesses various features, including anti-VM, self-deletion, persistence, file grabbing, and file loading capabilities. Additionally, the malware is reported to target Chromium-based browsers, Discord data, as well as applications like FileZilla, Foxmail, InternetDownloadManager, OBS Studio, OpenVPN, Pidgin, ProtonVPN, Signal, Telegram, and WinSCP.

Furthermore, Pure Logs is capable of extracting data from Mozilla Firefox, Waterfox, K-Meleon, Thunderbird, Comodo IceDragon, and various other applications. Concerning cryptocurrency apps, Pure Logs allegedly pilfers information from a range of extensions, including:

BitApp Wallet, BitClip, BitKeep, Binance Chain Wallet, Braavos Smart Wallet, Coin98 Wallet, Coinbase Wallet, Cyano Wallet, EOS Authenticator, EQUAL Wallet, Exodus Web3, Finnie, GAuth Authenticator, Guarda Wallet, iWallet, Jaxx Liberty, Keplr, Liquality Wallet, Math Wallet, MetaMask, MOBOX WALLET, Nifty Wallet, Phantom, Rabet, Ronin Wallet, Solana Wallet, Swash, TezBox, Terra Station, Trust Wallet, Waves Keeper, Wombat, Yoroi, and ZilPay.

Most threat actors aim to steal sensitive data such as login information (usernames, passwords, etc.), autofill data, credit card details, ID card information, social security numbers, 2FA data, and more. They misuse extracted information to steal identities, online accounts, and money, to make fraudulent purchases, and for other malicious purposes.

It is important to mention that information-stealing malware like PureLogs can have a keylogger module. They can log all data typed with the keyboard (record keyboard input). Thus, having a computer infected with malware of this type can cause huge damage (mostly financial).

Examples of similar malware

Examples of different information stealers are Titan, Nosu, and Doenerium. It is common for them to be leased using the Malware-as-a-Service (MaaS) model - their creators are selling them to other cybercriminals. Computers infected with information stealers should be scanned with antivirus software as soon as possible.

How did PureLogs infiltrate my computer?

PureLogs has been observed being delivered via email. Threat actors send emails containing malicious links to trick recipients into infecting their computers. The link in these emails downloads a ZIP file containing a malicious .bat file (with the ".pdf" extension in its filename). PureLogs gets downloaded after executing that .bat file.

How to avoid installation of malware?

Download software from official websites and stores. Avoid downloads from shady pages, P2P networks (e.g., torrent clients, eMule), third-party downloaders, free file hosting websites, etc. Double-check emails that have links or files in them. Avoid opening links or attachments in irrelevant emails from unknown addresses.

Do not trust advertisements on dubious pages (e.g., illegal movie streaming and torrent sites). Keep the operating system and installed software updated. Never use unofficial/third-party tools to update or activate any software.

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.
