“The Shocking Truth: How N.K. Hackers Used Matryoshka Doll-Style Attack on 3CX – Are You Next?”
North Korean hackers are upping their game with a new technique called “Matryoshka doll-style”. The term refers to the technique of hiding malicious code within legitimate code layers, making it more difficult to detect and prevent cyber attacks.
This method was used recently in attacks against banks in Russia and the United States. The hackers would first send an email with an attached document containing a benign-looking macro. Once downloaded, the macro would extract a hidden file with malicious code, allowing the hackers access to the victim’s information.
The hackers’ use of this technique highlights the sophistication and creativity of their attacks. It is yet another reminder of the need for individuals and organizations to remain vigilant in protecting themselves against cyber attacks.
Cybersecurity experts advise taking measures such as using strong passwords, regularly backing up data, and being cautious when opening email attachments or clicking on links from unknown sources.
In addition to these measures, it is important to stay informed about emerging threats and to stay up to date on the latest software updates and security patches. By remaining vigilant and taking proactive steps to protect against cyber attacks, individuals and organizations can prevent or minimize the impact of these incidents.
