Jupyter Infostealer

The Jupyter Infostealer, also known as Yellow Cockatoo, SolarMarker, and Polazert, is a harmful malware that has been steadily evolving since 2020. This malicious software targets Chrome and Firefox browser data, exploiting and damaging systems it infiltrates. It can infect systems through suspicious downloads, emails, or websites, often without the user's knowledge. Once inside, it can steal personal information, disrupt operations, or even hold your data hostage for ransom. This malware specifically targets sectors such as education, healthcare, and small to medium enterprises (SMEs). It is designed to extract and steal valuable information from these sectors, potentially causing significant harm and disruption. The malware has been linked to an increasing number of infections in these areas, demonstrating its effectiveness and widespread reach. In November 2023, a new, stealthier version of the Jupyter Infostealer was discovered. This updated variant was delivered through an MSI installer, showing an evolution in its delivery methods and further enhancing its stealth capabilities. The discovery of this new variant underscores the ongoing threat posed by the Jupyter Infostealer and the need for robust cybersecurity measures to combat it.
