Shortly after Microsoft announced support for custom JavaScript functions in Excel, someone demonstrated what could possibly go wrong if this feature is abused for malicious purposes. As promised last year at Microsoft's Ignite 2017 conference, the company has now brought custom JavaScript functions to Excel to extend its capabilities for better work with data. Functions are written in JavaScript for Excel spreadsheets currently runs on various platforms, including Windows, macOS, and Excel Online, allowing developers to create their own powerful formulae. But we saw it coming: Security researcher Charles Dardaman leveraged this feature to show how easy it is to embed the infamous in-browser cryptocurrency mining script from CoinHive inside an MS Excel spreadsheet and run it in the background when opened. "In order to run Coinhive in Excel, I followed Microsoft's official documentation and just added my own function," Dardaman said . Here is an official doc

A critical remote code execution vulnerability has been discovered in CyberArk Enterprise Password Vault application that could allow an attacker to gain unauthorized access to the system with the privileges of the web application. Enterprise password manager (EPV) solutions help organizations securely manage their sensitive passwords, controlling privileged accounts passwords across a wide range of client/server and mainframe operating systems, switches, databases, and keep them safe from external attackers, as well as malicious insiders. Discovered by German cybersecurity firm RedTeam Pentesting GmbH, the vulnerability affects one of such Enterprise Password Vault apps designed by CyberArk—a password management and security tool that manages sensitive passwords and controls privileged accounts. The vulnerability (CVE-2018-9843) resides in CyberArk Password Vault Web Access, a .NET web application created by the company to help its customers access their accounts remotely.

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

The growing popularity of Bitcoin and other cryptocurrencies is generating curiosity—and concern—among security specialists. Crypto mining software has been found on user machines, often installed by botnets. Organizations need to understand the risks posed by this software and what actions, if any, should be taken. To better advise our readers, we reached out to the security researchers at Cato Networks. Cato provides a cloud-based SD-WAN that includes FireWall as a Service (FWaaS) . Its research team, Cato Research Labs, maintains the company's Cloud IPS, and today released a list of crypto mining pool addresses that you can use as a blacklist in your firewall. (To download the list, visit this page .) Cato Research Labs determined crypto mining represents a moderate threat to the organization. Immediate disruption of the organization infrastructure or loss of sensitive data is not likely to be a direct outcome of crypto mining. However, there are significant risks of i

Security researchers have discovered a potentially dangerous vulnerability in the firmware of various Hewlett Packard (HP) enterprise printer models that could be abused by attackers to run arbitrary code on affected printer models remotely. The vulnerability (CVE-2017-2750), rated as high in severity with 8.1 CVSS scale, is due to insufficiently validating parts of Dynamic Link Libraries (DLL) that allows for the potential execution of arbitrary code remotely on affected 54 printer models. The security flaw affects 54 printer models ranging from HP LaserJet Enterprise, LaserJet Managed, PageWide Enterprise and OfficeJet Enterprise printers. This remote code execution (RCE) vulnerability was discovered by researchers at FoxGlove Security when they were analyzing the security of HP's MFP-586 printer (currently sold for $2,000) and HP LaserJet Enterprise M553 printers (sold for $500). According to a technical write-up posted by FoxGlove on Monday, researchers were able to

Recent corporate breaches have taught us something important — the average enterprise user is spectacularly bad at choosing good passwords. As modern enterprise is becoming a hybrid organization with infrastructure spread across on-premises data centers as well as in the cloud, security of information, applications, and assets has become a paramount concern. Cyber security is no longer an optional strategy for businesses, where limited visibility into the password practices of employees and ineffective monitoring of privileged credentials could end up an organization with a serious security breach and identity theft. The first line of defense for any organization or company is passwords, but most organizations grossly underestimate the need to comply with corporate password policies and meet IT regulatory requirements. Large enterprises have a policy in place that requires end users to choose strong passwords that can withstand dictionary and brute-force attacks, but it come
