Twitter has announced that it's limiting the use of SMS-based two-factor authentication (2FA) to its Blue subscribers. "While historically a popular form of 2FA, unfortunately we have seen phone-number based 2FA be used – and abused – by bad actors," the company  said . "We will no longer allow accounts to enroll in the text message/SMS method of 2FA unless they are Twitter Blue subscribers." Twitter users who have not subscribed to Blue that have enrolled for SMS-based 2FA have time till March 20, 2023, to switch to an alternative method such as an authenticator app or a hardware security key. After this cutoff date, non-Twitter Blue subscribers will have their option disabled. The alternative methods "require you to have physical possession of the authentication method and are a great way to ensure your account is secure," Twitter noted. Given that SMS has been the  least secure form of 2FA , the latest enforcement is likely to force people

A group of Chinese hackers carrying out political espionage for Beijing has been found targeting telecommunications companies with a new piece of malware designed to spy on text messages sent or received by highly targeted individuals. Dubbed " MessageTap ," the backdoor malware is a 64-bit ELF data miner that has recently been discovered installed on a Linux-based Short Message Service Center (SMSC) server of an unnamed telecommunications company. According to a recent report published by FireEye's Mandiant firm, MessageTap has been created and used by APT41 , a prolific Chinese hacking group that carries out state-sponsored espionage operations and has also been found involved in financially motivated attacks. In mobile telephone networks, SMSC servers act as a middle-man service responsible for handling the SMS operations by routing messages between senders and recipients. Since SMSes are not designed to be encrypted, neither on transmitting nor on the telec

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.

Mobile carriers in the United States will finally offer a universal cross-carrier communication standard for the next-generation RCS messaging service that is meant to replace SMS and has the potential to change the way consumers interact with brands for years to come. All major United States mobile phone carriers, including AT&T, Verizon, T-Mobile, and Sprint, have joined forces to launch a new initiative that will replace SMS with RCS mobile messaging standard . What's more? The initiative is also working with its carrier ownership group and other companies to develop and deploy the new RCS standard in a new text messaging app for Android phones that is expected to be launched in 2020. The goal of this joint venture , dubbed the Cross Carrier Messaging Initiative (CCMI) , is to deliver the GSMA's Rich Communications Service (RCS) industry standard to consumers and businesses on each of the four carriers, both in the United States and globally.
