More Than One Thousand Researchers and Threat Hunters First to Preview Newly Published YARA Rules for Detecting Top Windows and Linux Malware Families
CAMBRIDGE, Mass. - June 30, 2020 – ReversingLabs, the leading provider of explainable threat intelligence solutions, made a sizable contribution to the open source community today, publishing 128 of its rigorously tested YARA rules to GitHub for the first time. Announced at ReversingLabs inaugural threat hunter summit REVERSING 2020, these now publicly available rules enable threat defenders to detect a multitude of prominent and prevalent malware downloaders, viruses, trojans, exploits, and ransomware, including WannaCry, Ryuk, GandCrab, TrickBot and others. With free access to these rules that generate precise and accurate results and attribution, threat defenders now have the ability to more quickly pivot from a malware detection event to threat response.
“Knowing that a YARA rule has detected ransomware with high degree of precision can mean the difference between a prevented attack and the one that slips by because it was left waiting for investigation to elevate its importance,” said Tomislav Pericin, Chief Software Architect and Co-Founder, ReversingLabs. “Threat hunters can confidently add these YARA rules to their toolkit. They are built to provide zero false-positive detections. Only those that pass rigorous testing against our 10 billion unique binaries get published, ensuring quality and efficacy.”
Leveraging ReversingLabs extensive repository of 10 billion goodware and malware samples, deep understanding of destructive objects, and its analysts’ nearly two decades of threat hunting experience, these malware detection rules help threat hunters and other threat defenders attribute malware by type and family or variety to expedite threat response processes and reduce malware infection risk for their organizations. The rules can also be used to upskill threat defenders by showcasing high quality malware detection rules that consist of patterns that identify malicious code blocks.
In its first release of open source YARA rules, ReversingLabs focused on those that would help close detection gaps for deployed security solutions by focusing on the most destructive malware types, including: WannaCry, Multigrain, MedusaLocker, Kovter, Ryuk, GandCrab, Crysis, TrickBot, Emotet, Dridex, and CurveBall (CVE-2020-0601).
Availability & Support
The initial list of YARA rules can be accessed immediately via ReversingLabs GitHub repository. ReversingLabs will be responsible for maintaining the repository, providing regular updates, and adding new rules over time for detecting the latest threats. For questions, suggestions and guidance, threat hunters can contact ReversingLabs at email@example.com or open an issue on the GitHub repository.
ReversingLabs first 100 open source YARA rules were announced in a presentation by Pericin during REVERSING 2020, a free virtual summit that brought together more than 1,300 threat hunters, thought leaders, and security practitioners to discuss YARA best practices to assist in hunting, identifying, and classifying malware samples. Keynote speaker Vitali Kremez discussed “Evolution of Cybercrime Intent & Hunting with YARA for Malware Developers” and was joined by a host of other presenters discussing best practices, free tools, and new strategies for effectively using YARA. A full agenda from the event as well as presentation recordings from the REVERSING 2020 summit will be available on ReversingLabs YouTube channel and website starting the week of July 6.
