🚨 New Java-Based NS-STEALER Malware Stealing Data via Discord Bot! πŸŒπŸ’»

Cybersecurity researchers have unearthed a sophisticated threat known as NS-STEALER. This Java-based information stealer deploys a Discord bot to slyly exfiltrate sensitive data from compromised hosts. πŸ˜±πŸ”’

πŸ•΅οΈ Propagation Tactics

Disguised within ZIP archives as cracked software, the malware unfolds through a rogue Windows shortcut file, “Loader GAYve.” This shortcut serves as the gateway to unleash a malicious JAR file, creating a folder to stash stolen data called “NS-<11-digit_random_number>.”

πŸ“ Data Harvesting

NS-STEALER goes beyond basic tricks, snagging screenshots, cookies, credentials, autofill data from various web browsers, system info, program lists, Discord tokens, Steam, and Telegram session data. The sophistication lies in its use of X509Certificate for authentication, enabling swift data theft through Java Runtime Environment.

πŸ“‘ Exfiltration Channel

The captured intel finds its way to a Discord Bot channel, making the entire operation cost-effective for the threat actors.

πŸ”„ Chaes Malware Update

Meanwhile, the Chaes (aka Chae$) malware creators roll out version 4.1, enhancing the Chronod module for pilfering login credentials and intercepting crypto transactions. The infection chains leverage Portuguese-themed email lures to trick recipients into activating Chae$ 4.1.

πŸ‘Ύ Developer Messages

In an intriguing turn, the malware developers include messages within the source code, expressing gratitude to security researcher Arnold Osipov for aiding in software improvement. 🀝

🚨 MavenGate Unveiled – Java and Android Software Supply Chain Under Threat! πŸŒπŸ’»

Who’s that knocking at the door…. A novel software supply chain attack dubbed MavenGate is targeting public Java and Android libraries, exploiting abandoned but still-used projects. πŸ˜±πŸ”’

πŸ›‘οΈ Attack Methodology

Oversecured reveals that access to projects can be hijacked through domain name purchases. Due to vulnerabilities in default build configurations, it becomes challenging to detect these attacks. Successful exploitation could empower malicious actors to infiltrate dependencies, inject harmful code into applications, and even compromise the build process via a malicious plugin.

πŸ“± Vulnerable Technologies

All Maven-based technologies, including Gradle, are susceptible to this attack. Reports have been sent to over 200 companies, including tech giants Google, Facebook, Signal, Amazon, and others.

🎯 Modus Operandi

The attacker targets expired reversed domains owned by dependency owners and gains access to groupIds. This is achieved by asserting rights through DNS TXT records in repositories where no account managing the vulnerable groupId exists. If the groupId is registered, attackers may contact the repository’s support team.

πŸ’‘ Demonstration of the Attack

Oversecured demonstrated the attack by uploading a test Android library to Maven Central and JitPack, showcasing the ease with which an attacker can manipulate the dependency resolution in Gradle build scripts.

πŸ›‘ Detection Challenges

Most applications lack robust dependency signature checks, and libraries often do not publish digital signatures. This allows attackers to remain undetected by releasing new library versions with embedded malicious code.

🌐 Scope of Vulnerability

Out of 33,938 analysed domains, 18.18% were found vulnerable to MavenGate, giving threat actors the potential to hijack dependencies and introduce their code.

πŸ”’ Response from Sonatype (Maven Central)

Sonatype contends that the outlined attack strategy is not feasible due to existing automation. It has disabled accounts associated with expired domains and GitHub projects, addressing a regression in public key validation processes. Plans are underway to collaborate with SigStore for component digital signatures.

πŸš€ Call to Action

The responsibility for security lies with end developers for both direct and transitive dependencies. Library developers should declare dependencies responsibly and include public key hashes. Vigilance is crucial!

🚨 ScarCruft Strikes Again in Targeted Campaign Against Media and Experts! 🌐

In December 2023, a new campaign orchestrated by the infamous ScarCruft targeted media organisations and North Korean affairs experts. This threat actor, also known as APT37, InkySquid, RedEyes, Ricochet Chollima, and Ruby Sleet, is suspected to be part of the Ministry of State Security (MSS), operating independently from Lazarus Group and Kimsuky. πŸ˜±πŸ’»

πŸ” Modus Operandi

ScarCruft, associated with strategic espionage, is experimenting with fresh infection chains. In a notable move, it employed a technical threat research report as a decoy, likely targeting cybersecurity professionals and consumers of threat intelligence. πŸ•΅οΈβ€β™‚οΈπŸ“

🎯 Noteworthy Targets

High-profile experts in North Korean affairs were singled out, with the attacker posing as a member of the North Korea Research Institute. The decoy involved a ZIP archive file containing presentation materials, harbouring two malicious Windows shortcut (LNK) files.

πŸ’Ό Attack Techniques

The infection sequence mirrors a multi-stage approach used in a prior campaign, employing the RokRAT backdoor. The attackers are actively planning and testing their techniques, evident from malware like “intelligence.lnk” and “news.lnk” as well as shellcode variants delivering RokRAT. πŸ›‘οΈπŸ’Ό

πŸ“… Timeline

Some individuals targeted in this campaign were also identified as victims in a previous attack around November 16, 2023, showcasing the sustained and strategic nature of these cyber-espionage efforts.

πŸ“ˆ Adaptation

ScarCruft’s adjustments in its tactics indicate an ongoing effort to evade detection, particularly following public disclosures about its methods. The threat actor remains dedicated to acquiring strategic intelligence, possibly seeking insights into non-public cyber threat intelligence and defence strategies.

πŸ€” Analysis

By targeting media and experts, ScarCruft aims to gain a deeper understanding of international perceptions of developments in North Korea, contributing to the nation’s decision-making processes.
