Bitcoin Core Team Releases Critical Security Update to Fix DDoS Attack Vulnerability

1 min read

Recently, the Bitcoin core team released necessary updates to fix DDoS vulnerabilities in the software. If exploited, the entire network will crash.

Although blockchain and bitcoin are considered to be very secure emerging network technologies, there is no nightmare of software that can completely escape the loopholes.

The security vulnerability numbered CVE-2018-17144 has been around for three years, but it has not been discovered in the past few years.

Any miner can exploit this vulnerability to crash the Bitcoin core node of version 0.14.0 to 0.16.2. Of course, there is a price to pay for the block node to crash.

Simply put, anyone can participate in bitcoin mining and exploit vulnerabilities to create duplicate transactions, which will continue to consume block network bandwidth resources.

However, it takes about 12.5 bitcoins to use the vulnerability successfully, and 12.5 bitcoins are exchanged for $80,000 (£60,000) based on the current market price.

It may also be because of this reason that the vulnerability has only been announced until now, and it may have been noticed by hackers earlier, but it still has no return after all.

The Bitcoin core team said that all affected versions should be upgraded to version 0.16.3 immediately, which fixes other issues in addition to the DDoS vulnerability.
