Researchers Uncover Wiretapping of XMPP-Based Instant Messaging Service

Researchers Uncover Wiretapping of XMPP-Based Instant Messaging Service

Oct 28, 2023 Privacy / Data Security
New findings have shed light on what's said to be a lawful attempt to covertly intercept traffic originating from jabber[.]ru (aka xmpp[.]ru), an  XMPP -based instant messaging service, via servers hosted on Hetzner and Linode (a subsidiary of Akamai) in Germany. "The attacker has issued several new TLS certificates using Let's Encrypt service which were used to hijack encrypted  STARTTLS connections  on port 5222 using transparent [man-in-the-middle] proxy," a security researcher who goes by the alias ValdikSS  said  earlier this week. "The attack was discovered due to the expiration of one of the MiTM certificates, which haven't been reissued." Evidence gathered so far points to the traffic redirection being configured on the hosting provider network, ruling out other possibilities, such as a server breach or a spoofing attack. The wiretapping is estimated to have lasted for as long as six months, from April 18, 2023, although it's been confi

Act Now: VMware Releases Patch for Critical vCenter Server RCE Vulnerability

Oct 25, 2023 Vulnerability / Cyber Threat
VMware has released security updates to address a critical flaw in the vCenter Server that could result in remote code execution on affected systems. The issue, tracked as  CVE-2023-34048  (CVSS score: 9.8), has been described as an out-of-bounds write vulnerability in the implementation of the  DCE/RPC protocol . "A malicious actor with network access to vCenter Server may trigger an out-of-bounds write potentially leading to remote code execution," VMware  said  in an advisory published today. Credited with discovering and reporting the flaw is Grigory Dorodnov of Trend Micro Zero Day Initiative. VMware said that there are no workarounds to mitigate the shortcoming and that security updates have been made available in the following versions of the software - VMware vCenter Server 8.0 (8.0U1d or 8.0U2) VMware vCenter Server 7.0 (7.0U3o) VMware Cloud Foundation 5.x and 4.x Given the criticality of the flaw and the lack of temporary mitigations, the virtualization
How to Increase Engagement with Your Cybersecurity Clients Through vCISO Reporting

How to Increase Engagement with Your Cybersecurity Clients Through vCISO Reporting

Jul 22, 2024vCISO / Business Security
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.
Make API Management Less Scary for Your Organization

Make API Management Less Scary for Your Organization

Oct 24, 2023 API Management / Cybersecurity
While application development has evolved rapidly, the API management suites used to access these services remain a spooky reminder of a different era. Introducing new API management infrastructure with these legacy models still poses challenges for organizations as they modernize. Transitioning from monolithic architectures to agile microservices empowers developers to make quick changes. Using serverless technologies and containers enables rapid scalability. Adopting cloud-native API management further enhances developer productivity and leaves the ghosts of outdated operations behind. This blog uncovers the risks of neglecting API modernization and highlights how Gloo Gateway enhances upstream projects like Envoy with essential enterprise features like security, observability, and API controls. What's more, as a Kubernetes-native solution, Gloo Gateway seamlessly integrates with the Kubernetes API for easy deployment. Gloo Gateway adds enterprise capabilities to upstream open sou

Signal Messenger Introduces PQXDH Quantum-Resistant Encryption

Signal Messenger Introduces PQXDH Quantum-Resistant Encryption

Sep 20, 2023 Encryption / Privacy
Encrypted messaging app Signal has announced an update to the Signal Protocol to add support for quantum resistance by upgrading the Extended Triple Diffie-Hellman ( X3DH ) specification to Post-Quantum Extended Diffie-Hellman ( PQXDH ). "With this upgrade, we are adding a layer of protection against the threat of a quantum computer being built in the future that is powerful enough to break current encryption standards," Signal's Ehren Kret  said . The development comes weeks after Google added support for  quantum-resistant encryption algorithms  in its Chrome web browser and announced a  quantum-resilient FIDO2 security key implementation  as part of its OpenSK security keys initiative last month. The  Signal Protocol  is a set of cryptographic specifications that provides end-to-end encryption (E2EE) for private text and voice communications. It's used in various messaging apps like WhatsApp and Google's encrypted RCS messages for Android. While quantum c

Meta Set to Enable Default End-to-End Encryption on Messenger by Year End

Aug 23, 2023 Encryption / Privacy
Meta has once again reaffirmed its plans to roll out support for end-to-end encryption ( E2EE ) by default for one-to-one friends and family chats on Messenger by the end of the year. As part of that effort, the social media giant said it's upgrading "millions more people's chats" effective August 22, 2023, exactly seven months after it  started gradually expanding the feature  to more users in January 2023. The changes are part of CEO Mark Zuckerberg's "privacy-focused vision for social networking" that was announced in 2019, although it has since encountered significant technical challenges, causing it to  delay its plans  by a year. "Like many messaging services, Messenger and Instagram DMs were originally designed to function via servers," Timothy Buck, product manager for Messenger,  said . "Meta's servers act as the gateway between the message sender and receiver, what we call the clients." However, the addition of an
