Cybersecurity researchers are warning about an increase in phishing attacks that are capable of draining cryptocurrency wallets. "These threats are unique in their approach, targeting a wide range of blockchain networks, from Ethereum and Binance Smart Chain to Polygon, Avalanche, and almost 20 other networks by using a crypto wallet-draining technique," Check Point researchers Oded Vanunu, Dikla Barda, and Roman Zaikin  said . A prominent contributor to this troubling trend is a notorious phishing group called Angel Drainer, which advertises a "scam-as-a-service" offering by charging a percentage of the stolen amount,  typically 20% or 30% , from its collaborators in return for providing wallet-draining scripts and other services. In late November 2023, a similar wallet-draining service known as Inferno Drainer announced that it was  shutting down its operations  for good after helping scammers plunder over $70 million worth of crypto from 103,676 victims sinc

A group of academics from the University of California, Santa Barbara, has demonstrated what it calls a "scalable technique" to vet smart contracts and mitigate state-inconsistency bugs, discovering 47 zero-day vulnerabilities on the Ethereum blockchain in the process. Smart contracts are  programs  stored on the blockchain that are automatically executed when predetermined conditions are met based on the encoded terms of the agreement. They allow trusted transactions and agreements to be carried out between anonymous parties without the need for a central authority. In other words, the code itself is meant to be the final arbiter of "the deal" it represents, with the program controlling all aspects of the execution, and providing an immutable evidentiary audit trail of transactions that are both trackable and irreversible. This also means that vulnerabilities in the code could result in hefty losses, as evidenced by hacks aimed at  the DAO  and more recently, 

As a vCISO, you are responsible for your client's cybersecurity strategy and risk governance. This incorporates multiple disciplines, from research to execution to reporting. Recently, we published a comprehensive playbook for vCISOs, "Your First 100 Days as a vCISO – 5 Steps to Success" , which covers all the phases entailed in launching a successful vCISO engagement, along with recommended actions to take, and step-by-step examples.  Following the success of the playbook and the requests that have come in from the MSP/MSSP community, we decided to drill down into specific parts of vCISO reporting and provide more color and examples. In this article, we focus on how to create compelling narratives within a report, which has a significant impact on the overall MSP/MSSP value proposition.  This article brings the highlights of a recent guided workshop we held, covering what makes a successful report and how it can be used to enhance engagement with your cyber security clients.

Security researchers have discovered a series of new vulnerabilities in EOS blockchain platform, one of which could allow remote hackers to take complete control over the node servers running the critical blockchain-based applications. EOS is an open source smart contract platform, known as 'Blockchain 3.0,' that allows developers to build decentralized applications over blockchain infrastructure, just like Ethereum. Discovered by Chinese security researchers at Qihoo 360 —Yuki Chen of Vulcan team and Zhiniang Peng of Core security team—the vulnerability is a buffer out-of-bounds write issue which resides in the function used by nodes server to parse contracts. To achieve remote code execution on a targeted node, all an attacker needs to do is upload a maliciously crafted WASM file (a smart contract) written in WebAssembly to the server. As soon as the vulnerable process parser reads the WASM file, the malicious payload gets executed on the node, which could then al
