In yet another sign that developers continue to be targets of software supply chain attacks, a number of malicious packages have been discovered on the Rust programming language's crate registry. The libraries, uploaded between August 14 and 16, 2023, were published by a user named "amaperf," Phylum  said  in a report published last week. The names of the packages, now taken down, are as follows: postgress, if-cfg, xrvrv, serd, oncecell, lazystatic, and envlogger. It's not clear what the end goal of the campaign was, but the suspicious modules were found to harbor functionalities to capture the operating system information (i.e., Windows, Linux, macOS, or Unknown) and transmit the data to a hard-coded Telegram channel via the messaging platform's API. This suggests that the campaign may have been in its early stages and that the threat actor may have been casting a wide net to compromise as many developer machines as possible to deliver rogue updates with imp...

A Rust variant of a ransomware strain known as  Agenda  has been observed in the wild, making it the latest malware to adopt the cross-platform programming language after  BlackCat, Hive, Luna, and RansomExx . Agenda , attributed to an operator named Qilin, is a ransomware-as-a-service (RaaS) group that has been linked to a spate of attacks primarily targeting manufacturing and IT industries across different countries. A previous version of the ransomware, written in Go and customized for each victim, singled out healthcare and education sectors in countries like Indonesia, Saudi Arabia, South Africa, and Thailand. Agenda, like Royal ransomware , expands on the idea of partial encryption (aka intermittent encryption) by configuring parameters that are used to determine the percentage of file content to be encrypted. "This tactic is becoming more popular among ransomware actors as it lets them encrypt faster and avoid detections that heavily rely on read/write file ...

The operators of the RansomExx ransomware have become the latest to develop a new variant fully rewritten in the Rust programming language, following other strains like  BlackCat ,  Hive , and  Luna . The latest version, dubbed RansomExx2 by the threat actor known as Hive0091 (aka DefrayX), is primarily designed to run on the Linux operating system, although it's expected that a Windows version will be released in the future. RansomExx, also known as Defray777 and Ransom X, is a  ransomware   family  that's known to be active since 2018. It has since been linked to a number of attacks on government agencies, manufacturers, and other high-profile entities like Embraer and GIGABYTE. "Malware written in Rust often benefits from lower [antivirus] detection rates (compared to those written in more common languages) and this may have been the primary reason to use the language," IBM Security X-Force researcher Charlotte Hammond  said  in a report p...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...

Google on Tuesday announced that its open source version of the Android operating system will add support for Rust programming language in a bid to prevent memory safety bugs. To that end, the company has been building parts of the Android Open Source Project (AOSP) with Rust for the past 18 months, with plans in the pipeline to scale this initiative to cover more aspects of the operating system. "Managed languages like Java and Kotlin are the best option for Android app development," Google  said . "The Android OS uses Java extensively, effectively protecting large portions of the Android platform from memory bugs. Unfortunately, for the lower layers of the OS, Java and Kotlin are not an option." Stating that code written in C and C++ languages requires robust isolation when parsing untrustworthy input, Google said the technique of containing such code within a tightly constrained and unprivileged sandbox can be expensive, causing latency issues and additional...
