Signal Introduces Usernames, Allowing Users to Keep Their Phone Numbers Private

Signal Introduces Usernames, Allowing Users to Keep Their Phone Numbers Private

Feb 21, 2024 Secure Communication / Anonymity
End-to-end encrypted (E2EE) messaging app Signal said it's piloting a new feature that allows users to create unique usernames (not to be confused with profile names) and keep the phone numbers away from prying eyes. "If you use Signal, your phone number will no longer be visible to everyone you chat with by default," Signal's Randall Sarafa  said . "People who have your number saved in their phone's contacts will still see your phone number since they already know it." Setting a new username requires account holders to provide two or more numbers at the end of it (e.g., axolotl.99) in an effort to keep them "egalitarian and minimize spoofing." Usernames can be changed any number of times, but it's worth noting that they are not logins or handles. Put differently, a username is an anonymous way to initiate conversations on the chat platform without having to share phone numbers. The feature is opt-in, although Signal said it's also taking steps to hide by default users' phone numb
Patchwork Using Romance Scam Lures to Infect Android Devices with VajraSpy Malware

Patchwork Using Romance Scam Lures to Infect Android Devices with VajraSpy Malware

Feb 05, 2024 Cyber Espionage / Cyber Extortion
The threat actor known as Patchwork likely used romance scam lures to trap victims in Pakistan and India, and infect their Android devices with a remote access trojan called  VajraSpy . Slovak cybersecurity firm ESET said it uncovered 12 espionage apps, six of which were available for download from the official Google Play Store and were collectively downloaded more than 1,400 times between April 2021 and March 2023. "VajraSpy has a range of espionage functionalities that can be expanded based on the permissions granted to the app bundled with its code," security researcher Lukáš Štefanko  said . "It steals contacts, files, call logs, and SMS messages, but some of its implementations can even extract WhatsApp and Signal messages, record phone calls, and take pictures with the camera." As many as 148 devices in Pakistan and India are estimated to have been compromised in the wild. The malicious apps distributed via Google Play and elsewhere primarily masqueraded
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
Signal Debunks Zero-Day Vulnerability Reports, Finds No Evidence

Signal Debunks Zero-Day Vulnerability Reports, Finds No Evidence

Oct 16, 2023 Zero Day / Vulnerability
Encrypted messaging app Signal has pushed back against "viral reports" of an alleged zero-day flaw in its software, stating it found no evidence to support the claim. "After responsible investigation *we have no evidence that suggests this vulnerability is real* nor has any additional info been shared via our official reporting channels," it  said  in a series of messages posted in X (formerly Twitter). Signal said it also checked with the U.S. government and that it found no information to suggest "this is a valid claim." It's also urging those with legitimate information to send reports to security@signal[.]org. The development comes as  reports   circulated  over the  weekend  about a zero-day vulnerability in Signal that could be exploited to gain complete access to a targeted mobile device. As a security precaution, it's been advised to turn off  link previews  in the app. The feature can be disabled by going to Signal Settings > Chats

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
Okta Hackers Behind Twilio and Cloudflare Attacks Hit Over 130 Organizations

Okta Hackers Behind Twilio and Cloudflare Attacks Hit Over 130 Organizations

Aug 25, 2022
The threat actor behind the attacks on  Twilio  and  Cloudflare  earlier this month has been linked to a broader phishing campaign aimed at 136 organizations that resulted in a cumulative compromise of 9,931 accounts. The activity has been condemned  0ktapus  by Group-IB because the initial goal of the attacks was to "obtain Okta identity credentials and two-factor authentication (2FA) codes from users of the targeted organizations." Calling the attacks well designed and executed, the Singapore-headquartered company said the adversary singled out employees of companies that are customers of identity services provider Okta. The modus operandi involved sending targets text messages containing links to phishing sites that impersonated the Okta authentication page of the respective targeted entities. "This case is of interest because despite using low-skill methods it was able to compromise a large number of well-known organizations," Group-IB  said . "Furthe

Signal CEO Resigns, WhatsApp Co-Founder Takes Over as Interim CEO

Jan 11, 2022
Moxie Marlinspike, the founder of the popular encrypted instant messaging service Signal, has announced that he is stepping down as the chief executive of the non-profit in a move that has been underway over the last few months. "In other words, after a decade or more, it's difficult to overstate how important Signal is to me, but I now feel very comfortable replacing myself as CEO based on the team we have, and also believe that it is an important step for expanding on Signal's success," Marlinspike  said  in a blog post on Monday. Executive chairman and WhatsApp co-founder Brian Acton, who famously urged users to #DeleteFacebook in March 2018 and founded the Signal Foundation along with Marlinspike after he walked away from the social media giant in 2017 over a conflict with Facebook's plans to monetize WhatsApp, will serve as the interim CEO while the search for a replacement is on. Founded in July 2014, Signal has more than 40 million monthly users, in
