Google has disclosed that the company's continued adoption of the Rust programming language in Android has resulted in the number of memory safety vulnerabilities falling below 20% of total vulnerabilities for the first time. "We adopted Rust for its security and are seeing a 1000x reduction in memory safety vulnerability density compared to Android’s C and C++ code. But the biggest surprise was Rust's impact on software delivery," Google's Jeff Vander Stoep said . "With Rust changes having a 4x lower rollback rate and spending 25% less time in code review, the safer path is now also the faster one." The development comes a little over a year after the tech giant disclosed that its transition to Rust led to a decline in memory safety vulnerabilities from 223 in 2019 to less than 50 in 2024. The company pointed out that Rust code requires fewer revisions, necessitating about 20% fewer revisions than their C++ counterparts, and has contributed to a d...

Cybersecurity researchers have discovered two new extensions on Microsoft Visual Studio Code (VS Code) Marketplace that are designed to infect developer machines with stealer malware. The VS Code extensions masquerade as a premium dark theme and an artificial intelligence (AI)-powered coding assistant, but, in actuality, harbor covert functionality to download additional payloads, take screenshots, and siphon data. The captured information is then sent to an attacker-controlled server. "Your code. Your emails. Your Slack DMs. Whatever's on your screen, they're seeing it too," Koi Security's Idan Dardikman said . "And that's just the start. It also steals your WiFi passwords, reads your clipboard, and hijacks your browser sessions." The names of the extensions are below - BigBlack.bitcoin-black (16 installs) - Removed by Microsoft on December 5, 2025  BigBlack.codo-ai (25 installs) - Removed by Microsoft on December 8, 2025 Microsoft's l...

Targets located in Azerbaijan have been singled out as part of a new campaign that's designed to deploy Rust-based malware on compromised systems. Cybersecurity firm Deep Instinct is tracking the operation under the name Operation Rusty Flag. It has not been associated with any known threat actor or group. "The operation has at least two different initial access vectors," security researchers Simon Kenin, Ron Ben Yizhak, and Mark Vaitzman  said  in an analysis published last week. "One of the lures used in the operation is a modified document that was used by the Storm-0978 group. This could be a deliberate 'false flag.'" The attack chain leverages an LNK file named 1.KARABAKH.jpg.lnk as a launchpad to retrieve a second-stage payload, an MSI installer, hosted on Dropbox. The installer file, for its part, drops an implant written in Rust, an XML file for a scheduled task to execute the implant, and a decoy image file that features watermarks of the ...

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...

Indian government entities and the defense sector have been targeted by a phishing campaign that's engineered to drop Rust-based malware for intelligence gathering. The activity, first detected in October 2023, has been codenamed  Operation RusticWeb  by enterprise security firm SEQRITE. "New Rust-based payloads and encrypted PowerShell commands have been utilized to exfiltrate confidential documents to a web-based service engine, instead of a dedicated command-and-control (C2) server," security researcher Sathwik Ram Prakki  said . Tactical overlaps have been uncovered between the cluster and those widely tracked under the monikers  Transparent Tribe  and SideCopy, both of which are assessed to be linked to Pakistan. SideCopy is also a suspected subordinate element within Transparent Tribe. Last month, SEQRITE  detailed  multiple campaigns undertaken by the threat actor targeting Indian government bodies to deliver numerous trojans such as AllaKo...

Cybersecurity researchers have discovered two malicious Rust crates impersonating a legitimate library called fast_log to steal Solana and Ethereum wallet keys from source code. The crates, named faster_log and async_println, were published by the threat actor under the alias rustguruman and dumbnbased on May 25, 2025, amassing 8,424 downloads in total, according to software supply chain security company Socket. "The crates include working logging code for cover and embed routines that scan source files for Solana and Ethereum private keys, then exfiltrate matches via HTTP POST to a hardcoded command and control (C2) endpoint," security researcher Kirill Boychenko said . Following responsible disclosure, the maintainers of crates.io have taken steps to remove the Rust packages and disable the two accounts. It has also preserved logs of the threat actor-operated users along with the malicious crates for further analysis. "The malicious code was executed at runtime...

The maintainers of the Rust programming language have released a security update for a high-severity vulnerability that could be abused by a malicious party to purge files and directories from a vulnerable system in an unauthorized manner. "An attacker could use this security issue to trick a privileged program into deleting files and directories the attacker couldn't otherwise access or delete," the Rust Security Response working group (WG)  said  in an  advisory  published on January 20, 2021. Rust 1.0.0 through Rust 1.58.0 is affected by this vulnerability. The flaw, which is tracked as  CVE-2022-21658  (CVSS score: 7.3), has been credited to security researcher Hans Kratz, with the team pushing out a fix in  Rust version 1.58.1  shipped last week. Specifically, the issue stems from an improperly implemented check to prevent recursive deletion of symbolic links (aka  symlinks ) in a standard library function named "std::fs::remove_dir...

A critical security flaw in the Rust standard library could be exploited to target Windows users and stage command injection attacks. The vulnerability, tracked as  CVE-2024-24576 , has a CVSS score of 10.0, indicating maximum severity. That said, it only impacts scenarios where batch files are invoked on Windows with untrusted arguments. "The Rust standard library did not properly escape arguments when invoking batch files (with the bat and cmd extensions) on Windows using the Command API," the Rust Security Response working group  said  in an advisory released on April 9, 2024. "An attacker able to control the arguments passed to the spawned process could execute arbitrary shell commands by bypassing the escaping." The flaw impacts all versions of Rust before 1.77.2. Security researcher  RyotaK  has been credited with discovering and reporting the bug to the CERT Coordination Center ( CERT/CC ). RyotaK said the vulnerability – codenamed BatBadBut – impa...

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...

Cybersecurity researchers on Monday disclosed a new malspam campaign distributing a fresh variant of a malware loader called "Buer" written in Rust, illustrating how adversaries are constantly honing their malware toolsets to evade analysis. Dubbed "RustyBuer," the malware is propagated via emails masquerading as shipping notices from DHL Support, and is said to have affected no fewer than 200 organizations across more than 50 verticals since early April. "The new Buer variant is written in Rust, an efficient and easy-to-use programming language that is becoming increasingly popular," Proofpoint researchers  said  in a report shared with The Hacker News. "Rewriting the malware in Rust enables the threat actor to better evade existing Buer detection capabilities." First introduced in August of 2019,  Buer  is a modular malware-as-a-service offering that's sold on underground forums and used as a first-stage downloader to deliver additiona...

Cybersecurity researchers have shed light on a Rust version of a cross-platform backdoor called  SysJoker , which is assessed to have been used by a Hamas-affiliated threat actor to target Israel amid the ongoing war in the region. “Among the most prominent changes is the shift to Rust language, which indicates the malware code was entirely rewritten, while still maintaining similar functionalities,” Check Point  said  in a Wednesday analysis. “In addition, the threat actor moved to using OneDrive instead of Google Drive to store dynamic C2 (command-and-control server) URLs.” SysJoker was  publicly documented  by Intezer in January 2022, describing it as a C++ backdoor capable of gathering system information and establishing contact with an attacker-controlled server by accessing a text file hosted on Google Drive that contains a hard-coded URL. “Being cross-platform allows the malware authors to gain advantage of wide infection on all major platforms,” VMw...

Details have emerged about what's the first Rust-language-based ransomware strain spotted in the wild that has already amassed "some victims from different countries" since its launch last month. The ransomware, dubbed  BlackCat , was  disclosed  by MalwareHunterTeam. "Victims can pay with Bitcoin or Monero," the researchers said in a series of tweets detailing the file-encrypting malware. "Also looks they are giving credentials to intermediaries" for negotiations. BlackCat, akin to many other variants that have sprung before it, operates as a ransomware-as-a-service (RaaS), wherein the core developers recruit affiliates to breach corporate environments and encrypt files, but not before stealing the said documents in a double extortion scheme to pressure the targets into paying the requested amount or risk exposure of the stolen data should the companies refuse to pay up. Security researcher Michael Gillespie  called  it a "very sophisticated...

Google has revealed that its transition to memory-safe languages such as Rust as part of its secure-by-design approach has led to the percentage of memory-safe vulnerabilities discovered in Android dropping from 76% to 24% over a period of six years. The tech giant said focusing on Safe Coding for new features not only reduces the overall security risk of a codebase, but also makes the switch more "scalable and cost-effective." Eventually, this leads to a drop in memory safety vulnerabilities as new memory unsafe development slows down after a certain period of time, and new memory safe development takes over, Google's Jeff Vander Stoep and Alex Rebert said in a post shared with The Hacker News. Perhaps even more interestingly, the number of memory safety vulnerabilities tends to register a drop notwithstanding an increase in the quantity of new memory unsafe code. The paradox is explained by the fact that vulnerabilities decay exponentially, with a study finding ...

A new malware campaign is distributing a novel Rust-based information stealer dubbed EDDIESTEALER using the popular ClickFix social engineering tactic initiated via fake CAPTCHA verification pages. "This campaign leverages deceptive CAPTCHA verification pages that trick users into executing a malicious PowerShell script, which ultimately deploys the infostealer, harvesting sensitive data such as credentials, browser information, and cryptocurrency wallet details," Elastic Security Labs researcher Jia Yu Chan said in an analysis. The attack chains begin with threat actors compromising legitimate websites with malicious JavaScript payloads that serve bogus CAPTCHA check pages, which prompt site visitors to "prove you are not [a] robot" by following a three-step process, a prevalent tactic called ClickFix . This involves instructing the potential victim to open the Windows Run dialog prompt, paste an already copied command into the "verification window"...

Cybersecurity researchers have disclosed details of a new banking malware targeting Brazilian users that's written in Rust, marking a significant departure from other known Delphi-based malware families associated with the Latin American cybercrime ecosystem. The malware, which is designed to infect Windows systems and was first discovered last month, has been codenamed VENON by Brazilian cybersecurity company ZenoX. What makes VENON notable is that it shares behaviors that are consistent with established banking trojans targeting the region, such as Grandoreiro, Mekotio, and Coyote, specifically when it comes to features like banking overlay logic, active window monitoring, and a shortcut (LNK) hijacking mechanism. The malware has not been attributed to any previously documented group or campaign. However, an earlier version of the artifact, dating back to January 2026, has been found to expose full paths from the malware author's development environment. The paths repea...

Threat actors are increasingly shifting to "exotic" programming languages such as Go, Rust, Nim, and Dlang that can better circumvent conventional security protections, evade analysis, and hamper reverse engineering efforts. "Malware authors are known for their ability to adapt and modify their skills and behaviors to take advantage of newer technologies,"  said  Eric Milam, Vice President of threat research at BlackBerry. "That tactic has multiple benefits from the development cycle and inherent lack of coverage from protective products." On the one hand, languages like Rust are more secure as they offer guarantees like  memory-safe programming , but they can also be a double-edged sword when malware engineers abuse the same features designed to offer increased safeguards to their advantage, thereby making malware less susceptible to exploitation and thwart attempts to  activate a kill-switch  and render them powerless. Noting that binaries written i...

Cybersecurity researchers have disclosed details of a high-severity flaw impacting the popular async-tar Rust library and its forks, including tokio-tar, that could result in remote code execution under certain conditions. The vulnerability, tracked as CVE-2025-62518 (CVSS score: 8.1), has been codenamed TARmageddon by Edera, which discovered the issue in late August 2025. It impacts several widely-used projects, such as testcontainers and wasmCloud. "In the worst-case scenario, this vulnerability has a severity of 8.1 (High) and can lead to Remote Code Execution (RCE) through file overwriting attacks, such as replacing configuration files or hijacking build backends," the Seattle-based security company said . The problem is compounded by the fact that tokio-tar is essentially abandonware despite attracting thousands of downloads via crates.io. Tokio-tar is a Rust library for asynchronously reading and writing TAR archives built atop the Tokio runtime for the programmi...

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 ...
