Ethical Hacking News
A new threat has emerged, with North Korean hackers using a Linux-based FASTCash malware to steal millions from ATMs. The attack tool, previously used to target Windows and IBM AIX systems, has now been adapted for Linux distributions, posing an even greater challenge to security professionals in the fight against cybercrime.
The FASTCash malware has been updated with a new Linux variant that bears striking similarities to its Windows and AIX predecessors. The threat actors behind the malware are state-backed North Korean hacking group 'Hidden Cobra,' linked to several high-profile cyberattacks. The malware operates by intercepting and manipulating ISO8583 transaction messages, allowing hackers to initiate unauthorized cash withdrawals from ATMs. Financial institutions and individuals must remain vigilant and take proactive measures to protect themselves from these types of attacks. Implementing robust security protocols and staying informed about emerging threats is essential for maintaining a strong defense against sophisticated attacks.
In a shocking revelation, security researcher HaxRob has uncovered a new variant of the FASTCash malware, a notorious Linux-based attack tool used by North Korean hackers to steal millions of dollars from ATMs across multiple countries. The latest variant, recently discovered on VirusTotal in June 2023, bears striking similarities to its Windows and AIX predecessors but boasts several key improvements that make it even more formidable.
The FASTCash malware has been a thorn in the side of financial institutions and governments alike for over seven years, with its origins dating back to at least 2016. According to various reports, including those from the US Cyber Command and CISA (Cybersecurity and Infrastructure Security Agency), the threat actors responsible for the malware are none other than the state-backed North Korean hacking group known as 'Hidden Cobra.' The group's activities have been linked to several high-profile cyberattacks, with one notable incident involving the theft of over $1.3 billion from financial institutes worldwide.
The FASTCash malware operates by intercepting and manipulating ISO8583 transaction messages used in the financial industry for debit and credit card processing. Specifically, it targets messages related to declines of transactions due to insufficient funds in the cardholder's account. The malicious code replaces the "decline" response with "approve," allowing the hackers to initiate unauthorized cash withdrawals from ATMs.
In a typical scenario, money mules acting on behalf of the hackers would withdraw the stolen cash from an ATM after receiving approval codes (DE38, DE39) and amounts (DE54) transmitted back to the bank's central systems. The manipulation of these transaction messages enables the attackers to bypass traditional security measures and carry out their nefarious plans.
The discovery of this new Linux variant of FASTCash marks a significant escalation in the threat landscape, as it highlights the North Korean hackers' ability to adapt and evolve their tactics to evade detection. This latest development comes on the heels of a recent report by HaxRob revealing a previously undetected Windows version of the malware submitted to VirusTotal in September 2024. It appears that the hackers are actively working on refining their toolset, making it even more challenging for security professionals to detect and mitigate these threats.
In light of this new information, financial institutions and individuals must remain vigilant and take proactive measures to protect themselves from these types of attacks. Implementing robust security protocols, such as regular software updates, patch management, and network monitoring, can help minimize the risk of infection by malware like FASTCash. Furthermore, staying informed about emerging threats and adjusting their security strategies accordingly is essential for maintaining a strong defense against these sophisticated attacks.
The revelation of this new Linux variant serves as a stark reminder that cybersecurity threats are constantly evolving, and it is crucial to stay ahead of the curve in order to protect oneself and one's organization from such nefarious activities.
