How to Remove Odyssey Information Stealer

Odyssey is a sophisticated piece of malware that falls under the category of information stealers, specifically targeting macOS users. As a variant of the well-known AMOS (Atomic) Stealer, Odyssey has gained notoriety for its ability to quietly infiltrate Apple systems and extract a wide array of sensitive data—ranging from login credentials and browser data to cryptocurrency wallet contents and keychain-stored information.

Odyssey’s emergence highlights an increasing trend: macOS is no longer a safe haven from malware. Cybercriminals have evolved, and so have their tools. Odyssey is proof that even Apple users are now under siege from high-level information theft.

What Does Odyssey Do?

Once installed, Odyssey begins by harvesting technical device data—such as model name, UUID, OS version, CPU details, and RAM. This initial profiling helps the malware tailor its actions depending on the system environment.

Next, it seeks permission to access key user folders like Desktop and Documents, enabling it to download files directly from the system. One of its most dangerous capabilities is its access to macOS Keychain, a vault containing sensitive information like saved Wi-Fi credentials, website logins, and even credit card data.

Odyssey is designed to infiltrate and extract data from multiple popular web browsers, including:

• Google Chrome
• Brave
• Mozilla Firefox
• Microsoft Edge
• Opera & OperaGX
• Vivaldi
• Yandex

In addition to credentials and autofill data, Odyssey can tap into browser-based cryptocurrency wallets and extensions, making it a serious threat to crypto holders.

Why Odyssey Is So Dangerous

What makes Odyssey especially threatening is its silent operation. Most users will not detect its presence until after damage is done. It hides in plain sight, requiring no user interaction after its deceptive installation, and proceeds to loot the victim’s digital life with precision.

Cybercriminals use the stolen data to:

• Hijack email, social media, banking, and gaming accounts
• Commit identity fraud
• Conduct unauthorized purchases
• Send phishing or scam messages using compromised accounts
• Sell stolen data on the dark web
