Hackers Increasingly Using WebAssembly Coded Cryptominers to Evade Detection

Hackers Increasingly Using WebAssembly Coded Cryptominers to Evade Detection
Jul 26, 2022
As many as 207 websites have been infected with malicious code designed to launch a cryptocurrency miner by leveraging WebAssembly (Wasm) on the browser. Web security company Sucuri, which published details of the campaign, said it launched an investigation after one of its clients had their computer slowed down significantly every time upon navigating to their own WordPress portal. This uncovered a compromise of a theme file to inject malicious JavaScript code from a remote server -- hxxps://wm.bmwebm[.]org/auto.js -- that's loaded whenever the website's page is accessed. "Once decoded, the contents of auto.js immediately reveal the functionality of a cryptominer which starts mining when a visitor lands on the compromised site," Sucuri malware researcher Cesar Anjos  said . What's more, the deobfuscated auto.js code makes use of WebAssembly to run low-level binary code directly on the browser. WebAssembly , which is supported by all major browsers, is a  b

Critical RCE Flaw Discovered in Blockchain-Based EOS Smart Contract System

Critical RCE Flaw Discovered in Blockchain-Based EOS Smart Contract System
May 29, 2018
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

6 Ways to Simplify SaaS Identity Governance

6 Ways to Simplify SaaS Identity Governance
Feb 21, 2024SaaS Security / Identity Management
With SaaS applications now making up the vast majority of technology used by employees in most organizations, tasks related to identity governance need to happen across a myriad of individual SaaS apps. This presents a huge challenge for centralized IT teams who are ultimately held responsible for managing and securing app access, but can't possibly become experts in the nuances of the native security settings and access controls for hundreds (or thousands) of apps. And, even if they could, the sheer volume of tasks would easily bury them. Modern IT teams need a way to orchestrate and govern SaaS identity governance by engaging the application owners in the business who are most familiar with how the tool is used, and who needs what type of access.  Nudge Security is a  SaaS security and governance solution  that can help you do just that, with automated workflows to save time and make the process manageable at scale. Read on to learn how it works. 1 . Discover all SaaS apps used b

WebAssembly — New Standard for Powerful and Faster Web Apps

WebAssembly — New Standard for Powerful and Faster Web Apps
Jun 23, 2015
Google, Apple, Microsoft , and Mozilla have joined hands to create code for use in the future web browsers that promises up to 20 times faster performance. Dubbed WebAssembly (or wasm for short), a project to create a new portable bytecode for the Web that will be more efficient for both desktop as well as mobile web browsers to parse than the complete source code of a Web page or an application. Bytecode is actually a machine-readable instruction set that is faster for web browsers to load than high-level languages. WebAssembly — A New File Format to Compile Code At the moment, browsers use JavaScript to interpret the code and allow functionality on websites such as dynamic content and forms. By default, JavaScript files are downloaded from the server and then compiled by the JavaScript engine in the web browser. However, improvements have been made to load times via Asm.js — the stripped-down JavaScript dialect described as an "assembly language for
