All the work presented in this blog post is open source and available as part of our Splunk Connect for Ethereum repository examples, including the instrumentation of Besu as a Docker container, the configuration of Splunk, and two applications showing how to monitor Besu syncing to the chain.

Identified as targeting cryptocurrency users through nefarious cross-platform applications, a remote access trojan (RAT) dubbed 'ElectroRAT' has recently been in the headlines following an investigation into the threat by researchers at Intezer.

With many financially-motivated threat actors targeting cryptocurrency, it comes as no surprise that users of 'Stellar', an opensource blockchain payment network, have recently been targeted in a somewhat convincing attack in an attempt to steal their holdings of Lumen (XLM), an 'altcoin' cryptocurrency.

In part two of this series, learn how to create a data model for the Bitcoin network protocol and use the Defensics SDK to perform fuzzing on bitcoind. In the previous article, you saw how to set up a test bed for bitcoind. We created two containers, fleur and viktor, and set up communication between the two bitcoind instances. In this article, learn how to create a data model for the Bitcoin network protocol, and then use this model in the Defensics® SDK to perform fuzzing on bitcoind.

This is the first part of a two-part advanced technical tutorial that describes how you can use the Defensics SDK to set up your own Bitcoin network. This is the first of two articles that describe how to use the Defensics® software development kit (SDK) to fuzz Bitcoin software. Specifically, you’ll learn how to model one of the Bitcoin network protocol messages and use the Defensics SDK to perform fuzzing on the bitcoind process.

European cryptocurrency exchange platform Eterbase has announced that it has suffered a security breach which saw malicious hackers access its network and steal funds worth US $5.4 million. In a message posted on Telegram, the Slovakian cryptocurrency exchange listed the six hot wallets plundered by cybercriminals for their Ether, Tezos, Bitcoin, ALGO, Ripple, and TRON riches.

The healthcare industry is transforming with the integration of ground-breaking technologies capable of storing patient records electronically. The shift to the digitization of systems makes a variety of healthcare solutions possible that never could have been imagined — but it also puts healthcare data at risk to hackers and cyber attacks. In answer to this problem, blockchain technologies are emerging as a viable option for the storage and updating of electronic health records (EHRs).

A couple of years ago, I wrote about why you don’t need a blockchain. Blockchain is one long transaction log that always gets written to and is never backed up. It’s a ledger, more or less, with some math. And while distributed ledgers can be useful for some scenarios, I’m here today to say you still don’t need a blockchain. What turns a distributed ledger into a blockchain is cryptography for creating a digital signature to reduce the risk of data tampering.

We recently published a blog post - the first of a nine-part series - on the Kubernetes attack matrix and the representative threat vectors that organizations must consider to adequately secure their Kubernetes environments.
