Trickbot Infects over 140,000 machines of customers from Amazon, Microsoft, Google, others worldwide

Check Point Research (CPR) discovers sophisticated details of the implementation of Trickbot, learning that the notorious banking trojan has infected over 140,000 machines of customers from Amazon, Microsoft, Google and 57 other corporations world-wide, since November 2020. Trickbot’s authors are selectively going after high-profile targets to steal and compromise their sensitive data. Additional, Trickbot’s infrastructure can be utilized by various malware families to cause more damage on infected machines. CPR urges the public to only open documents from trusted sources, as Trickbots authors are leveraging anti-analysis and anti-obfuscation techniques to persist on machines.

• CPR provides a list of 60 corporations whose customers have been infected by Trickbot
• Most infected regions in order: APAC, Latin America, Europe, Africa, North America
• CPR recommends three security and safety tips from Trickbot

Check Point Research (CPR) has discovered new and sophisticated details of the implementation of Trickbot. A well-known banking Trojan, Trickbot steals and compromises the data of its victims, targeting high-profile victims. CPR counts over 140,000 machines infected by Trickbot since November 2020, many of which are customers of well-known corporations, such as Amazon, Microsoft, Google and PayPal. In total, CPR documented 60 corporations whose customers have fallen victim to Trickbot throughout the past 14 months.

Key Implementation Details of Trickbot

• Malware is very selective in how it chooses its targets
• Various tricks – including anti-analysis and anti-Deobfuscation – implemented inside the modules show the authors’ highly technical background
• Trickbots infrastructure can be utilized by various malware families to cause more damage on infected machines
• Sophisticated and versatile malware with more than 20 modules that can be downloaded and executed on demand

How Trickbot Works:

1. Threat actors receive a database of stolen emails and send malicious documents to the chosen addresses
2. The user downloads and opens such a document, allowing macro execution in the process
3. The first stage of malware is executed, and the main Trickbot payload is downloaded
4. The main Trickbot payload is executed and establishes its persistence on the infected machine.
5. Auxiliary Trickbot modules can be uploaded to the infected machine on demand by the threat actors, the functionality of such modules may vary: it may be spreading via compromised corporate network, stealing corporate credentials, grabbing login details to banking sites, etc.

Quote: Alexander Chailytko, Cyber Security, Research & Innovation Manager at Check Point Software Technologies,

“Trickbot’s numbers have been staggering. We’ve documented over 140,000 machines targeting the customers of some of the biggest and most reputable companies in the world. We went onto observe that the Trickbot authors have the skills to approach malware development from a very low-level and pay attention to small details. Trickbot attacks high-profile victims to steal the credentials and provide its operators access to the portals with sensitive data where they can cause even more damage. At the same time, we know that the operators behind the infrastructure are very experienced with malware development on a high-level as well. The combination of these two factors is what allows Trickbot to remain a dangerous threat for more than 5 years already. I strongly urge people to only open documents from trusted sources and to use different passwords on different web-sites.”

Security Tips

1. Only open documents you receive from trusted sources. Do not enable macro execution inside the documents.
   2. Make sure you have the latest operating system and anti-virus updates up and running.
   3. Use different passwords on different web-sites.
