Microsoft Warns of Node.js Abuse for Malware Delivery
Microsoft Warns of Node.js Abuse for Malware Delivery
In the past months Microsoft has seen multiple campaigns involving Node.js to deliver malware and other malicious payloads. Microsoft on Tuesday issued a warning over the increasing use of Node.js for the delivery of malware and other malicious payloads. The tech giant has been seeing such attacks aimed at its customers since October 2024 and some of the observed campaigns are still active in April 2025.

Outlaw Linux Malware: Persistent, Unsophisticated, and Surprisingly Effective — Elastic Security Labs
Outlaw Linux Malware: Persistent, Unsophisticated, and Surprisingly Effective — Elastic Security Labs
OUTLAW is a persistent yet unsophisticated auto-propagating coinminer package observed across multiple versions over the past few years [1], [2], [3], [4]. Despite lacking stealth and advanced evasion techniques, it remains active and effective by leveraging simple but impactful tactics such as SSH brute-forcing, SSH key and cron-based persistence, and manually modified commodity miners and IRC channels. This persistence highlights how botnet operators can achieve widespread impact without relying on sophisticated techniques.

New TorNet backdoor seen in widespread campaign
New TorNet backdoor seen in widespread campaign
Cisco Talos discovered an ongoing malicious campaign operated by a financially motivated threat actor targeting users, predominantly in Poland and Germany. The actor has delivered different payloads, including Agent Tesla, Snake Keylogger, and a new undocumented backdoor we are calling TorNet, dropped by PureCrypter malware. The actor is running a Windows scheduled task on victim machines—including on endpoints with a low battery—to achieve persistence. The actor also disconnects the victim machine from the network before dropping the payload and then connects it back to the network, allowing them to evade detection by cloud antimalware solutions. We also found that the actor connects the victim’s machine to the TOR network using the TorNet backdoor for stealthy command and control (C2) communications and detection evasion.

Inside FireScam : An Information Stealer with Spyware Capabilities
Inside FireScam : An Information Stealer with Spyware Capabilities
  • FireScam is an information stealing malware with spyware capabilities. It is distributed as a fake ‘Telegram Premium’ APK via a phishing website hosted on the GitHub.io domain, mimicking the RuStore app store. The phishing website delivers a dropper that installs the FireScam malware disguised as the Telegram Premium application. The malware exfiltrates sensitive data, including notifications, messages, and other app data, to a Firebase Realtime Database endpoint. FireScam monitors device activities such as screen state changes, e-commerce transactions, clipboard activity, and user engagement to gather valuable information covertly. Captures notifications across various apps, including system apps, to potentially steal sensitive information and track user activities. It employs obfuscation techniques to hide its intent and evade detection by security tools and researchers. FireScam performs checks to identify if it is running in an analysis or virtualized environment. The malware leverages Firebase for command-and-control communication, data storage, and to deliver additional malicious payloads. Exfiltrated data is temporarily stored in the Firebase Realtime Database, filtered for valuable content, and later removed. The Firebase database reveals potential Telegram IDs linked to the threat actors and contains URLs to other malware specimens hosted on the phishing site. By exploiting the popularity of messaging apps and other widely used applications, FireScam poses a significant threat to individuals and organizations worldwide.

Information Stealer Masquerades as LDAPNightmare (CVE-2024-49113) PoC Exploit
Information Stealer Masquerades as LDAPNightmare (CVE-2024-49113) PoC Exploit
In December 2024, two critical vulnerabilities in Microsoft's Windows Lightweight Directory Access Protocol (LDAP) were addressed via Microsoft’s monthly Patch Tuesday release. Both vulnerabilities were deemed as highly significant due to the widespread use of LDAP in Windows environments: CVE-2024-49112: A remote code execution (RCE) bug that attackers can exploit by sending specially crafted LDAP requests, allowing them to execute arbitrary code on the target system. CVE-2024-49113: A denial-of-service (DoS) vulnerability that can be exploited to crash the LDAP service, leading to service disruptions. In this blog entry, we discuss a fake proof-of-concept (PoC) exploit for CVE-2024-49113 (aka LDAPNightmare) designed to lure security researchers into downloading and executing information-stealing malware.
