Summary

Intezer discovered a campaign targeting cryptocurrency users that they estimate began in early 2020. A new RAT associated with the campaign has been named ElectroRAT by Intezer. It is written in Golang and can run on Linux, MacOS, and Windows.

Threat Type

  • Malware

Overview

A campaign that targets cryptocurrency users was discovered by Intezer in late 2020. Intezer estimates the campaign began around January 2020. Three Trojanized applications (DaoPoker, eTrade, and Jamm) built using the Electron framework are used in the campaign to deliver a RAT that has been named ElectroRAT by Intezer. The applications have been promoted through fake user accounts on social media and online forums that focus on cryptocurrency, and are hosted on websites created for the campaign. ElectroRAT uses raw Pastebin pages to determine its C&C address and Intezer estimates, from the number of pages views, that there may be several thousand victims. While ElectroRAT can log keystrokes, take screenshots, upload and download files, and execute commands, its primary goal is to obtain access to the victim’s crypto wallets. Further information is available from the link in the Reference section below.

"collectionWikiContent": "Summary\nIntezer discovered a campaign targeting cryptocurrency users that they estimate began in early 2020. A new RAT associated with the campaign has been named ElectroRAT by Intezer. It is written in Golang and can run on Linux, MacOS, and Windows.\nThreat Type\nMalware\nOverview\nA campaign that targets cryptocurrency users was discovered by Intezer in late 2020. Intezer estimates the campaign began around January 2020. Three Trojanized applications (DaoPoker, eTrade, and Jamm) built using the Electron framework are used in the campaign to deliver a RAT that has been named ElectroRAT by Intezer. The applications have been promoted through fake user accounts on social media and online forums that focus on cryptocurrency, and are hosted on websites created for the campaign. ElectroRAT uses raw Pastebin pages to determine its C&C address and Intezer estimates, from the number of pages views, that there may be several thousand victims. While ElectroRAT can log keystrokes, take screenshots, upload and download files, and execute commands, its primary goal is to obtain access to the victim's crypto wallets. Further information is available from the link in the Reference section below.\nIndicators of Compromise\nA complete list of IoCs can be found in the Reports section to the right.\nRecommendations\nEnsure anti-virus software and associated files are up to date.\nSearch for existing signs of the indicated IoCs in your environment.\nConsider blocking and or setting up detection for all URL and IP based IoCs.\nKeep applications and operating systems running at the current released patch level.\nExercise caution with attachments and links in emails.\nReference\nhttps://www.intezer.com/blog/research/operation-electrorat-attacker-creates-fake-companies-to-drain-your-crypto-wallets/ ",
