Blockchain safety agency, Halborn has detected a number of crucial and exploitable vulnerabilities impacting greater than 280 networks, together with Litecoin (LTC) and Zcash (ZEC). Code-named “Rab13s,” this vulnerability has put over $25 billion of digital belongings in danger.

This was first detected within the Dogecoin community a yr in the past, which was then fastened by the staff behind the premier memecoin.

51% Assaults and Different Points

In accordance with the official blog post, Holborn researchers found probably the most crucial vulnerability associated to peer-to-peer (p2p) communications which, if exploited, may also help attackers craft consensus messages and ship them to particular person nodes and take them offline. Ultimately, such a risk might additionally expose networks to dangers similar to 51% assaults and different extreme points.

“An attacker can crawl the community friends utilizing getaddr message and assault the unpatched nodes.”

The agency recognized one other zero-day which was uniquely associated to Dogecoin, together with an RPC (Distant Process Name) Distant code execution vulnerability impacting particular person miners.

Variants of those zero-days have been additionally found in comparable blockchain networks, similar to Litecoin and Zcash. Whereas not all of the bugs are exploitable in nature as a result of variations in codebase between the networks, not less than one in every of them may very well be exploited by attackers on every community.


Within the case of weak networks, Halborn mentioned that profitable exploitation of the related vulnerability might result in denial of service or distant code execution.

The safety platform believes that the simplicity of those Rab13s vulnerabilities will increase the potential of assault.

Upon additional investigation, Halborn researchers discovered a second vulnerability within the RPC providers that enabled an attacker to crash the node through RPC requests. However profitable exploitation would require legitimate credentials. This reduces the potential of all the community being in danger as a result of some nodes implement the cease command.

A 3rd vulnerability, then again, lets malicious entities execute code within the context of the person working the node by means of the general public interface (RPC). The chance of this exploit can be low since even this requires a sound credential to hold out a profitable assault.

Bug Exploits

In the meantime, an exploit equipment for Rab13s has been developed that features a proof of idea with configurable parameters to display the assaults on numerous different networks.

Halborn has confirmed sharing all the mandatory technical particulars with the recognized stakeholders to assist them remediate the bugs, in addition to to launch the related patches for the group and miners.
