Importance of Dridex Malware

The term Dridex Malware is important because it represents a dangerous and persistent form of financial cybercrime, targeting personal banking information and businesses worldwide.

This Trojan-type malware, first detected in 2011, infiltrates computer systems through phishing emails and exploits software vulnerabilities, enabling cybercriminals to manipulate online banking transactions and steal funds.

Over the years, Dridex has evolved to become increasingly sophisticated, employing advanced techniques such as incorporating encryption and evading detection by various antivirus programs.

As a result, it has become crucial for individuals and organizations to be vigilant in their cybersecurity practices and stay updated on latest developments related to Dridex in order to effectively protect their sensitive financial data.


The Dridex malware, also known as Cridex or Bugat, is a Trojan horse created to serve one primary purpose – financial gain. It is designed to steal sensitive information, such as online banking credentials and other personal information, from its target’s devices. By doing so, Dridex allows cybercriminals to conduct unauthorized transactions and transfer funds from the victim’s account to their own, or even sell the stolen data on the dark web.

Since its emergence in 2011, Dridex has been at the center of several large-scale cyberattacks, with countless individuals and organizations falling victim to this sophisticated piece of malicious software. The malware typically infiltrates a victim’s device through targeted phishing campaigns sent via emails containing seemingly legitimate documents (like invoices or order confirmations) with hidden macro scripts. Once the unsuspecting user opens the attachment and enables macros, Dridex is activated and begins to work stealthily in the background.

It leverages a vast network of infected computers, known as botnets, to boost its ability to bypass security measures and remain undetected for extended periods. Additionally, Dridex is known for its adaptive capabilities, as its creators continually update the malware to evade newer security measures and maintain its effectiveness. For these reasons, Dridex is considered one of the most notorious and dangerous pieces of malware in the cyberthreat landscape.

Examples of Dridex Malware

February 2015 – Financial Sector Attack: In one of the earliest known instances of the Dridex malware, it was reported that cybercriminals had stolen more than $10 million from various financial institutions across the United States and Europe. The malware infected victims’ computers via malicious emails, and then it proceeded to harvest banking credentials to access and transfer funds.

October 2015 – UK Arrest and Take-down: In a joint operation between the UK’s National Crime Agency (NCA) and the US Federal Bureau of Investigation (FBI), a 30-year-old Moldovan man was arrested in Cyprus. He was suspected of being the mastermind behind the Dridex malware campaign, which had stolen an estimated $100 million globally. Following the arrest, security experts from TrendMicro and other top companies assisted in significantly disrupting the malware’s infrastructure, taking control of a large number of servers associated with it.

November 2020 – Dridex Campaign Targeting Job Seekers: In this example, the Dridex malware campaign targeted people looking for job opportunities. Cybercriminals sent phishing emails masquerading as legitimate job offers. The email contained a Word document or Excel file with macros that, when activated, installed the Dridex malware on the victim’s computer. Once the victim’s system was infected, the malware stole personal and financial information, which was then used for fraudulent activities.
