Meta Platforms on Monday announced that it has started to expand global testing of end-to-end encryption ( E2EE ) in Messenger chats by default. "Over the next few months, more people will continue to see some of their chats gradually being upgraded with an extra layer of protection provided by end-to-end encryption," Meta's Melissa Miranda  said . The social media behemoth said it intends to notify users in select individual chat threads as the security feature is enabled, while emphasizing that the process of choosing and upgrading the conversations to support E2EE is random. "It's designed to be random so that there isn't a negative impact on our infrastructure and people's chat experience," Miranda further explained. Along with flipping the switch on E2EE, Meta has also added more features into its encrypted chat experience, including support for themes, custom emojis and reactions, group profile photos, link previews, and active status.

Two security flaws have been disclosed in Samsung's Galaxy Store app for Android that could be exploited by a local attacker to stealthily install arbitrary apps or direct prospective victims to fraudulent landing pages on the web. The issues, tracked as  CVE-2023-21433 and CVE-2023-21434 , were  discovered  by NCC Group and notified to the South Korean chaebol in November and December 2022. Samsung  classified  the bugs as moderate risk and released fixes in version 4.5.49.8 shipped earlier this month. Samsung Galaxy Store, previously known as Samsung Apps and Galaxy Apps, is a dedicated app store used for Android devices manufactured by Samsung. It was launched in September 2009. The first of the two vulnerabilities is CVE-2023-21433, which could enable an already installed rogue Android app on a Samsung device to install any application available on the Galaxy Store. Samsung described it as a case of improper access control that it said has been patched...

The move to SaaS and other cloud tools has put an emphasis on Identity & Access Management (IAM). After all, user identity is one of the only barriers standing between sensitive corporate data and any unauthorized access.  The tools used to define IAM make up its identity fabric. The stronger the fabric, the more resistant identities are to pressure from threat actors. However, those pressures are only increasing. Decentralized IT, evolving threats, and zero-trust tools are pushing many IAM tools to their limits.  To maintain their effectiveness, IAM are shifting to operating as an agile, interconnected identity fabric rather than just siloed IAM tools. The demands of today’s IT operating environment are forcing IAM to support decentralized IT environments while still providing centralized management and governance for its users. Interestingly, many of the identity fabric principles they define are currently found in leading SSPM tools. It’s important to note that iden...

The legitimate command-and-control (C2) framework known as Sliver is  gaining   more traction  from threat actors as it emerges as an open source alternative to  Cobalt Strike  and Metasploit. The findings come from Cybereason, which  detailed  its inner workings in an exhaustive analysis last week. Sliver, developed by cybersecurity company BishopFox, is a Golang-based cross-platform post-exploitation framework that's designed to be used by security professionals in their red team operations. Its myriad features for adversary simulation – including dynamic code generation, in-memory payload execution, and process injection – have also made it an appealing tool for threat actors looking to gain elevated access to the target system upon gaining an initial foothold. In other words, the software is used as a second-stage to conduct next steps of the attack chain after already compromising a machine using one of the initial intrusion vectors such as...

Researchers have shut down an "expansive" ad fraud scheme that spoofed more than 1,700 applications from 120 publishers and impacted roughly 11 million devices.  "VASTFLUX was a malvertising attack that injected malicious JavaScript code into digital ad creatives, allowing the fraudsters to stack numerous invisible video ad players behind one another and register ad views," fraud prevention firm HUMAN  said . The operation gets its name from the use of a DNS evasion technique called  Fast Flux  and  VAST , a Digital Video Ad Serving Template that's employed to serve ads to video players. The sophisticated operation particularly exploited the restricted in-app environments that run ads on iOS to place bids for displaying ad banners. Should the auction be won, the hijacked ad slot is leveraged to inject rogue JavaScript that establishes contact with a remote server to retrieve the list of apps to be targeted. This includes the  bundle IDs  that bel...

Threat actors associated with the Roaming Mantis attack campaign have been observed delivering an updated variant of their patent mobile malware known as Wroba to infiltrate Wi-Fi routers and undertake Domain Name System ( DNS ) hijacking. Kaspersky, which carried out an  analysis  of the malicious artifact, said the feature is designed to target specific Wi-Fi routers located in South Korea. Roaming Mantis, also known as Shaoye, is a long-running financially motivated operation that singles out Android smartphone users with malware capable of stealing bank account credentials as well as harvesting other kinds of sensitive information. Although primarily  targeting the Asian region  since 2018, the hacking crew was detected  expanding  its  victim range  to include France and Germany for the first time in early 2022 by camouflaging the malware as the Google Chrome web browser application. The attacks leverage smishing messages as the initial...
