New Powerful Nullpoint-Stealer With Extensive Capabilities Hosted on GitHub
Summary:
Nullpoint-Stealer is a newly released, sophisticated information-stealing malware toolkit hosted on GitHub by a user named monroe31s. Nullpoint-Stealer has been marketed as an educational cybersecurity tool but has raised significant concerns due to its advanced capabilities and potential for misuse. Developed in C#, Nullpoint-Stealer is designed to extract a wide array of sensitive data from compromised systems, including passwords, cookies, bookmarks, autofill data, and browsing history from Chromium-based browsers. It also captures desktop screenshots, collects files from key directories like Desktop and Documents, and scans for installed VPN clients, gaming platforms (e.g., Steam, Epic Games), and cryptocurrency wallets such as Metamask and Exodus. The stealer’s modular architecture allows for easy extension of its capabilities, while its lightweight design ensures fast, stealthy operation. It features a control panel with detailed analytics categorized by country, OS, browser, and online services, enhancing its utility for attackers. Despite being labeled as a tool for malware analysis and ethical hacking training, cybersecurity experts emphasize that its functionality mirrors that of real-world malware, blurring the line between legitimate research and malicious intent.
Security Officer Comments:
The number of new information-stealing malware continues to grow at an alarming rate, providing cybercriminals with increasingly sophisticated tools to harvest sensitive data such as login credentials, personal information, and authentication tokens. These tools often serve as the first step in cyberattacks, allowing threat actors to gain an initial foothold within organizational networks and potentially escalate access to more critical and sensitive systems. The scale of this threat is alarming: in the past year alone, information-stealing malware infected over 18 million devices, resulting in the exposure and sale of more than 2.4 billion compromised credentials on underground markets. These stolen credentials are frequently exploited by attackers to facilitate further malicious activities, including data breaches and ransomware attacks, which can have devastating consequences for businesses and individuals alike.
Suggested Corrections:
Users should always be cautious of individuals or organizations that ask for personal information. Most companies will not ask for sensitive data from their customers. If in doubt, users should verify with the company itself to avoid any potential issues.
Users should always take a close look at the sender’s display name when checking the legitimacy of an email. Most companies use a single domain for their URLs and emails, so a message that originates from a different domain is a red flag.
As a general rule, users should not click links or download files even if they come from seemingly “trustworthy” sources.
Check for mismatched URLs. While an embedded URL might seem perfectly valid, hovering above it might show a different web address. In fact, users should avoid clicking links in emails unless they are certain that it is a legitimate link.
Users should always be on the lookout for any grammatical errors and spelling mistakes. Legitimate companies will often employ proofreaders and editors who ensure that the materials they send out are error-free.
Users should not be frightened or intimidated by messages that have an alarmist tone. They should double check with the company if they are uncertain about the status of their accounts.
Phishing emails are designed to be sent to a large number of people, so they need to be as impersonal as possible. Users should check whether the message contains a generic subject and greeting, as this can be a sign of a phishing attempt.
Although not every end user has access to advanced anti-phishing software, they can still use the built-in protection of their email clients to filter messages. One example is setting the email client to block all images unless approved.
Legitimate companies will never send confirmation emails unless there are specific reasons for doing so. In fact, most companies will avoid sending unsolicited messages unless it’s for company updates, newsletters, or advertising purposes.
Users should always take the context of an email or message into account. For example, most online accounts do away with viewable member numbers, so users should be wary if they receive emails containing a “member number” for services that generally don’t use them.
It is important to take note of unusual information in the text of the message. Any mentions of operating systems and software that are not typically used by consumers can often be indicators of a phishing attempt.
If it seems suspicious, it probably is. Users should always err on the side of caution when it comes to sending out personally identifiable information through messages and emails.
