CryptBot: A Threat to Chrome Users
Cryptbot is a malware that targets Chrome users who store or trade cryptocurrencies. It can steal your data and virtual wallets. Google says it infected 670,000 people in 2022. This article tells you how Cryptbot works, how to detect and remove it, and how to prevent future attacks.
Understanding Cryptbot Malware: A Comprehensive Guide to the Threats and Risks
Cryptbot malware is a serious concern for Chrome users, as it surreptitiously steals their confidential information and digital currencies by hiding in malicious extensions that are installed in the browser without their knowledge. Once installed, it can compromise sensitive information such as passwords, banking logins, private keys of cryptocurrencies and browsing history. Moreover, Cryptbot malware can add malicious code in the web pages to misappropriate cryptocurrencies from the users’ wallets or exchanges. Hence, the security threat posed by this malware is severe and requires immediate attention.
Cryptbot Malware: How it Steals Sensitive Data, Including Cryptocurrency Wallets, from Chrome Users
This type of Trojan malware was first detected in December 2019 and is known for disguising itself as authentic software such as Google Chrome or Google Earth Pro and can be downloaded from counterfeit websites. Upon download and installation, the computer gets infected with Cryptbot along with another Trojan, Vidar, both of which are created to identify and steal sensitive data of Chrome users like:
- Username and password that are saved in Chrome browser
- Browser cookies that may contain session or preference information
- Cryptocurrency wallet data, like Ethereum or Bitcoin
- Credit card information saved in the browser
- Desktop or window screenshots
The data that is collected can often be sold to other hackers who may use it for extortion campaigns or data breaches. Moreover, this malware is capable of taking screenshots of active windows or desktop, exposing even more confidential information. Therefore, Cryptbot malware endangers your privacy and security while putting online accounts, identity, money and personal safety at risk. It may also lead to further malware infections or phishing attempts. Hence, safeguarding against Cryptbot malware is essential, and it should be removed if detected.
CryptBot Malware: How It Spreads Through Fraudulent Websites and Phishing Campaigns, and Its Command and Control Server
CryptBot mainly spreads through fraudulent websites that offer modified or pirated versions of legitimate software such as Google Chrome or Google Earth Pro. These websites encourage users to download and run malicious files, which then install CryptBot on their computer.
This malware can also be distributed through phishing campaigns, which involve sending misleading emails to users, impersonating trusted entities such as Google or Microsoft. These emails often contain links or attachments infected.
Once installed on the victim’s computer, CryptBot connects to a command and control (C&C) server, which gives it instructions on the data to collect and send. CryptBot can automatically update itself to avoid detection and stay hidden on the victim’s computer.
Removing CryptBot Malware from Chrome
If you suspect that your Chrome browser is infected with CryptBot malware, you should take immediate action to remove it. Here are some steps you can follow to detect and remove CryptBot:
- Suspicious Extension Check: Open Chrome and click on the three dots icon on the top right corner. Go to More Tools > Extensions and look for any suspicious extensions that you do not recognize or do not remember installing. Remove them by clicking on the Remove button.
- Anti-Malware Software Use: Download and install a reputable anti-malware software such as Malwarebytes or Norton. Run a full system scan to detect and remove CryptBot malware from your computer.
- Chrome Settings Reset: Go to Chrome Settings > Advanced > Reset and clean up > Restore settings to their original defaults. This will reset your browser settings to their default state and remove any unwanted changes made by CryptBot.
- Password Change: If CryptBot has stolen your passwords, you should change them immediately for all affected accounts.
Detecting CryptBot Malware on Your Computer
It is not always easy to detect the presence of CryptBot on your computer, as it is a discreet and silent malware. However, there are some signs that can alert you:
- Your computer becomes slower or more unstable
- Your Chrome browser displays unwanted ads or redirects you to suspicious websites
- You receive security alerts or password reset requests from your online accounts
- You notice unusual or unauthorized transactions on your bank accounts or cryptocurrency wallets
If you notice any of these symptoms, it is possible that you are infected by CryptBot. In this case, it is recommended to scan your computer with a reliable and up-to-date antivirus, such as Bitdefender or Malwarebytes. If the scan detects the presence of CryptBot or other threats, follow the instructions to remove them.

Google’s Legal Action Against CryptBot Malware and Its Importance in Protecting Chrome Users
Google has successfully obtained a court order to remove current and future domains linked to the distribution of CryptBot, a malware that poses a threat to Chrome users. Google believes that legal action against such security threats, which abuse legitimate software like Chrome, can be effective. The company used a similar strategy against the alleged operators of the Russian botnet Glupteba in 2021, which resulted in a 78% reduction in Glupteba infections.
However, this court order does not mean that the danger of CryptBot is completely eliminated. The malware is constantly evolving and can still infect systems if users are not careful. It is strongly recommended to follow the advice here, including updating applications and operating systems, downloading software from reliable sources, and regularly checking for the presence of CryptBot.
If you want to review the court decision issued by Judge Valerie Figueredo of the Southern District Court of New York in response to Google LLC’s (“Google”) lawsuit against CryptBot infrastructure and distribution networks, which aimed to reduce the number of victims whose sensitive information, such as usernames, passwords, and cryptocurrencies, the malicious software steals, click on the following link to download the document.
Through this legal action, Google sought to reduce the number of victims who fall prey to CryptBot’s theft of sensitive information. This court decision is a crucial step in the fight against sophisticated and difficult-to-detect malware attacks such as CryptBot.

Malware Targeting Chrome Users: Understanding the Inner Workings of CryptBot
CryptBot is a type of malware that targets Chrome users by stealing their personal data, including cryptocurrency. But how does this malware infiltrate Chrome and avoid detection by antivirus software, and how does it communicate with its command server? Below is a brief technical explanation of CryptBot for those interested in the details:
- CryptBot is primarily spread through phishing campaigns that offer a fake Chrome update or other legitimate software that contains a hidden virus. Once installed, the virus creates four files in the %TEMP% folder and activates a disguised BAT file that injects CryptBot into Chrome’s legitimate process. This allows the malware to access and encrypt the user’s data using the AES algorithm before sending it to its command server via an HTTP POST request.
- In addition to stealing data, CryptBot can receive instructions from the command server via a JSON and AES-based communication protocol. These instructions can include downloading additional malware, updating the configuration settings, or deleting itself as needed.
- Although CryptBot is a dangerous form of malware, understanding how it works can help users protect themselves from future attacks.
In conclusion, the threat CryptBot poses to the security of your data and cryptocurrencies on Chrome is real, but there are steps you can take to protect yourself. By following the advice we have shared and using Freemindtronic’s EviVault technology embedded in cold wallets such as Keepser, you can strengthen the security of your computer and protect your cryptographic assets from hackers.
