The  NuGet  repository is the target of a new "sophisticated and highly-malicious attack" aiming to infect .NET developer systems with cryptocurrency stealer malware. The 13 rogue packages, which were downloaded more than 160,000 times over the past month, have since been taken down. "The packages contained a PowerShell script that would execute upon installation and trigger a download of a 'second stage' payload, which could be remotely executed," JFrog researchers Natan Nehorai and Brian Moussalli  said . While NuGet packages have been in the past found to  contain vulnerabilities  and be abused to  propagate phishing links , the development marks the first-ever discovery of packages with malicious code. Three of the most downloaded packages – Coinbase.Core, Anarchy.Wrapper.Net, and DiscordRichPresence.API – alone accounted for 166,000 downloads, although it's also possible that the threat actors artificially inflated the download counts using bo

New findings from cybersecurity firm JFrog show that malware targeting the npm ecosystem can evade security checks by taking advantage of an "unexpected behavior" in the npm command line interface (CLI) tool. npm CLI's  install  and  audit   commands  have built-in capabilities to check a package and all of its dependencies for known vulnerabilities, effectively acting as a warning mechanism for developers by highlighting the flaws. But as JFrog established, the security advisories are not displayed when the packages follow certain version formats, creating a scenario where critical flaws could be introduced into their systems either directly or via the package's dependencies. Specifically, the problem arises only when the installed package version contains a hyphen (e.g., 1.2.3-a), which is included to denote a  pre-release version  of an npm module. While the project maintainers treat the discrepancy between regular npm package versions and pre-release version

Cybersecurity researchers have detailed a recently patched high-severity security vulnerability in the popular Fastjson library that could be potentially exploited to achieve remote code execution. Tracked as  CVE-2022-25845  (CVSS score: 8.1), the  issue  relates to a case of  deserialization of untrusted data  in a supported feature called "AutoType." It was patched by the project maintainers in  version 1.2.83  released on May 23, 2022. "This vulnerability affects all Java applications that rely on Fastjson versions 1.2.80 or earlier and that pass user-controlled data to either the JSON.parse or JSON.parseObject APIs without specifying a specific  class  to deserialize," JFrog's Uriya Yavnieli  said  in a write-up. Fastjson  is a Java library that's used to convert Java Objects into their  JSON  representation and vice versa.  AutoType , the function vulnerable to the flaw, is enabled by default and is designed to specify a custom type when parsing

Cybersecurity researchers have discovered a number of malicious packages in the NPM registry specifically targeting a number of prominent media, logistics, and industrial firms based in Germany to carry out  supply chain attacks . "Compared with most malware found in the NPM repository, this payload seems particularly dangerous: a highly-sophisticated, obfuscated piece of malware that acts as a backdoor and allows the attacker to take total control over the infected machine," researchers from JFrog  said  in a new report. The DevOps company said that evidence points to it being either the work of a sophisticated threat actor or a "very aggressive" penetration test. All the rogue packages, most of which have since been removed from the repository, have been traced to four "maintainers" - bertelsmannnpm, boschnodemodules, stihlnodemodules, and dbschenkernpm — indicating an attempt to impersonate legitimate firms like Bertelsmann, Bosch, Stihl, and DB Sc

Cybersecurity researchers on Tuesday disclosed 14 critical vulnerabilities in the BusyBox Linux utility that could be exploited to result in a denial-of-service (DoS) condition and, in select cases, even lead to information leaks and remote code execution. The security weaknesses, tracked from CVE-2021-42373 through CVE-2021-42386, affect multiple versions of the tool ranging from 1.16-1.33.1, DevOps company JFrog and industrial cybersecurity company Claroty  said  in a joint report. Dubbed "the Swiss Army Knife of Embedded Linux,"  BusyBox  is a widely used software suite combining a variety of common Unix utilities or applets (e.g.,  cp ,  ls ,  grep ) into a single executable file that can run on Linux systems such as programmable logic controllers (PLCs), human-machine interfaces (HMIs), and remote terminal units (RTUs). A quick list of the flaws and the applets they impact is below — man  - CVE-2021-42373 lzma/unlzma  - CVE-2021-42374 ash  - CVE-2021-42375 hus
