browser-based threat report: crypto-mining software

browser-based threat report: crypto-mining software

This URL was first detected by ConcealBrowse on March 5th, the same day other security vendors started to report it. So far, one security vendor has flagged this page as malicious. ConcealBrowse intervened with a 30% risk assessment, citing proximity.

This page has a history of hosting crypto-mining software and delivering it to unsuspecting visitors. Crypto-miners, designed to utilize computer resources to generate digital currency, can negatively affect machines by causing performance issues and leaving the device open to security risks. Kryptex has been labeled by multiple vendors as adware, malware, and riskware, further highlighting the potential harm that may come from downloading it onto a computer.

Conceal Recommends: Consider adopting a company policy that bans crypto – mining software from company devices. ConcealBrowse’s intervention prevents the download of software while a website is in isolation.

browser-based threat report: adware

This URL was first detected by ConcealBrowse on March 5th, before other security vendors began reporting on it. As of today, one other security vendor has marked this URL as containing malware. ConcealBrowse successfully intervened with a 44% risk assessment, citing proximity and malware.

Although the page that this URL leads to is now blank, the IP address leads to multiple campaigns for distributing the Turbo Ad Blocker adware. This malicious software pretends to be an ad blocker to convince the user to download it. Once installed, it hijacks browsers, forcing users to go to unwanted sites and causing multiple pop-ups to occur. This can lead the user exposed to further security risks, as the sites and pop-ups are frequently spam or malicious.

Conceal Recommends: This URL and IP address should be blocked. Consider implementing company policies that prevent the installation of untrusted software onto company machines.

browser-based threat report: phishing, credential theft

webpage phishing for Outlook credentials

This URL was first detected by ConcealBrowse on March 5th. It was detected by fourteen vendors last November, and that same number continue to report it to date. ConcealBrowse assessed the page and intervened with a 28% risk assessment, citing suspicious activity.

This webpage is a phish for Outlook credentials. Email credentials continue to be highly sought after, due to their potential for access into other accounts that belong to that same user. Two-factor authentications that only require a verification email can become easily compromised, and email messages are the most common way to reset a forgotten password. Outlook’s popularity in the workforce may also lead to the theft of sensitive or confidential information using social engineering.

Conceal Recommends: This URL and IP address should be blocked. Consider utilizing a third-party 2FA application, instead of email messages, to prevent multiple account compromises.
