3CX Attack - What Happened?

This blog covers the 3cx attack, what happened and what we leant from the huge impact of this attack. For more depth, listen to our consultants discuss this in our ThreatBite.

3CX Attack - What Happened?

On the 2nd of March 2020, a security breach was detected in 3CX Phone System. Millions of businesses worldwide use this open-source VoIP solution for Windows, Linux, and Mac OS. Attackers could gain access to the 3CX central database and stole customer information such as names, and email addresses.


The attackers also accessed the 3CX server’s administrative panel, changing some settings and deploying malicious code. The attackers then used this malicious code to launch an attack on the vulnerable systems to gain further access. This allowed them to gain control of customer accounts, which resulted in potentially damaging data being stolen.


The 3CX team immediately took action to protect their customers by disabling the vulnerable server and deploying a patch to fix the vulnerability. They also requested customers to reset their passwords as an additional security measure.


What is the Aftermath of the Attack?

3CX quickly released a statement confirming that no customer's financial information was compromised, but it is yet unclear what other data was affected.


The attack has caused a number of issues for customers, including disruption to business operations and the potential risk of further cyberattacks. Many businesses have also had to take additional security measures in order to protect their systems from similar attacks in the future.


What Have We Learnt From this Attack?


The attack on 3CX highlights the importance of taking proactive security measures to protect against potential cyber threats. Businesses need to take all necessary steps to ensure their systems are secure, including implementing strong authentication and encryption protocols.


It also demonstrates the importance of regularly updating your systems and software. By staying up-to-date with the latest security patches, businesses can protect their systems from new vulnerabilities.


Finally, businesses need to have a response plan in place to minimize any disruption caused by an attack and ensure that customers are informed of any data breaches quickly. This will help mitigate any damage and potentially prevent future attacks.

Conclusion

Overall, this incident serves as an important reminder that all businesses need to stay vigilant and take extra steps to protect themselves from cyberattacks. It is important to be aware of any potential vulnerabilities in your software or hardware and ensure that all access control measures are up-to-date. Additionally, regular backups are essential in order to restore data if it's ever compromised quickly.
