The developers of Rspack have revealed that two of their npm packages, @rspack/core and @rspack/cli , were compromised in a software supply chain attack that allowed a malicious actor to publish malicious versions to the official package registry with cryptocurrency mining malware. Following the discovery , versions 1.1.7 of both libraries have been unpublished from the npm registry. The latest safe version is 1.1.8. "They were released by an attacker who gained unauthorized npm publishing access, and contain malicious scripts," software supply chain security firm Socket said in an analysis. Rspack is billed as an alternative to the webpack , offering a "high performance JavaScript bundler written in Rust." Originally developed by ByteDance, it has since been adopted by several companies such as Alibaba, Amazon, Discord, and Microsoft, among others. The npm packages in question, @rspack/core, and @rspack/cli, attract weekly downloads of over 300,000 and 145...

Juniper Networks is warning that Session Smart Router (SSR) products with default passwords are being targeted as part of a malicious campaign that deploys the Mirai botnet malware. The company said it's issuing the advisory after "several customers" reported anomalous behavior on their Session Smart Network (SSN) platforms on December 11, 2024. "These systems have been infected with the Mirai malware and were subsequently used as a DDoS attack source to other devices accessible by their network," it said . "The impacted systems were all using default passwords." Mirai , which has had its source code leaked in 2016, has spawned several variants over the years. The malware is capable of scanning for known vulnerabilities as well as default credentials to infiltrate devices and enlist them into a botnet for mounting distributed denial-of-service (DDoS) attacks. To mitigate such threats, organizations are recommended to change their passwords with i...

Cybersecurity researchers have discovered a new PHP-based backdoor called Glutton that has been put to use in cyber attacks targeting China, the United States, Cambodia, Pakistan, and South Africa. QiAnXin XLab, which discovered the malicious activity in late April 2024, attributed the previously unknown malware with moderate confidence to the prolific Chinese nation-state group tracked Winnti (aka APT41). "Interestingly, our investigation revealed that Glutton's creators deliberately targeted systems within the cybercrime market," the company said . "By poisoning operations, they aimed to turn the tools of cybercriminals against them – a classic 'no honor among thieves' scenario." Glutton is designed to harvest sensitive system information, drop an ELF backdoor component, and perform code injection against popular PHP frameworks like Baota (BT), ThinkPHP, Yii, and Laravel. The ELF malware also shares "near-complete similarity" with a know...

A now-removed GitHub repository that advertised a WordPress tool to publish posts to the online content management system (CMS) is estimated to have enabled the exfiltration of over 390,000 credentials. The malicious activity is part of a broader attack campaign undertaken by a threat actor, dubbed MUT-1244 (where MUT refers to "mysterious unattributed threat") by Datadog Security Labs, that involves phishing and several trojanized GitHub repositories hosting proof-of-concept (PoC) code for exploiting known security flaws. "Victims are believed to be offensive actors – including pentesters and security researchers, as well as malicious threat actors – and had sensitive data such as SSH private keys and AWS access keys exfiltrated," researchers Christophe Tafani-Dereeper, Matt Muir, and Adrian Korn said in an analysis shared with The Hacker News. It's no surprise that security researchers have been an attractive target for threat actors, including nation-sta...

A security flaw has been disclosed in OpenWrt 's Attended Sysupgrade ( ASU ) feature that, if successfully exploited, could have been abused to distribute malicious firmware packages. The vulnerability, tracked as CVE-2024-54143 , carries a CVSS score of 9.3 out of a maximum of 10, indicating critical severity. Flatt Security researcher RyotaK has been credited with discovering and reporting the flaw on December 4, 2024. The issue has been patched in ASU version 920c8a1 . "Due to the combination of the command injection in the imagebuilder image and the truncated SHA-256 hash included in the build request hash, an attacker can pollute the legitimate image by providing a package list that causes the hash collision," the project maintainers said in an alert. OpenWrt is a popular open-source Linux-based operating system for routers, residential gateways, and other embedded devices that route network traffic. Successful exploitation of the shortcoming could essentiall...

Cybersecurity researchers have uncovered a new Linux rootkit called PUMAKIT that comes with capabilities to escalate privileges, hide files and directories, and conceal itself from system tools, while simultaneously evading detection. "PUMAKIT is a sophisticated loadable kernel module (LKM) rootkit that employs advanced stealth mechanisms to hide its presence and maintain communication with command-and-control servers," Elastic Security Lab researchers Remco Sprooten and Ruben Groenewoud said in a technical report published Thursday. The company's analysis comes from artifacts uploaded to the VirusTotal malware scanning platform earlier this September. The internals of the malware is based on a multi-stage architecture that comprises a dropper component named "cron," two memory-resident executables ("/memfd:tgt" and "/memfd:wpn"), an LKM rootkit ("puma.ko"), and a shared object (SO) userland rootkit called Kitsune ("li...
