Computer and internet are now a part of our lives. Meanwhile, malware also takes its place on the internet. One of these programs, the malware Glupteba, which Google managed to take offline about a year ago, is back and seems more resilient than before.
Glupteba seems to be back after a 1 year hiatus
Cybersecurity experts announced that they found examples of reverse engineered Glupteba as well as TLS certificate records, blockchain transactions. While the malware has been found to be active since spring, it is stated that it may again be part of a large project.
It is known that the main purpose of Glupteba is to infect as many devices as possible and use them to create a botnet. Botnets can often be used for crypto mining operations, DDoS attacks, and hiring as a service to some malicious online.
Hackers hide inside SSD with malware!
According to the data revealed by the researchers of Korea University, hackers can hide on the SSD with malware.
The malware often disguises itself as free software and finds itself on the updated list of C2 servers via the Bitcoin blockchain. Not only is it financially easy to set up a C2 server, but with the Bitcoin blockchain being immutable, it is very difficult to crash the botnet.
The fact that transactions on the Bitcoin blockchain are open to everyone makes these transactions traceable. By analyzing the transactions made, it can be found who is behind each address or transaction. So far, it has been revealed that Glupteba’s operators use 15 Bitcoin addresses. The last address is said to have been activated in June 2022.
Glupteba’s previous malicious botnet was removed by Google in December 2021. The company managed to get a court order to confiscate the botnet’s infrastructure. Although it is thought that the danger has disappeared since then, the fact that Glupteba continues to work behind the scenes has created fear.
The number of malware operating in many areas is increasing day by day. It is worth saying that you should be very careful against these software. So what do you think about Glupteba? You can share your views with us in the comments section.
