Marked by the rise of the infamous Chimera, 2015 is officially proclaimed the year of the ransomware – over 700,000 new ransomware strains and 300$ million disbursed to malicious actors.Ĭonsidering the (exponential) growth rate, the pervasiveness, and the mutational factor (hundreds of new strains were engineered every single day by committing minute modifications to an existing strain). The number of novel ransomware strains would have increased by a factor of three, reaching 200,000 by the end of Q3 2011. A Varonis report reveals that in Q3 2011, approximately 60,000 new ransomware strains have been detected. Embracing the Endpoint Detection and Response Modelįull-scale adoption and deployment of the Endpoint Detection and Response model have been the primary goal of many businesses and institutions since 2011 – most cybersecurity analysts and researchers regard this year as a turning point (or boiling point) in malware evolution.

Feel free to consult her article for more information on how EDR changed the rules of the threat-hunting game. My colleague covered all of the forensics parts of EDR and other technicalities in a recently published material. There are other aspects worth taking into consideration – under EDR, digital/computer forensics become the ‘backbone’ of threat detection.Įven the terminology expedites the same conclusion – I.O.A (Indicator of Attack), I.O.C (Indicator of Compromise), HIPS (Host- Intrusion Prevention System), and HIDS (Host-Intrusion Detection System).
(Canonical AV-Centric Detection-Mediation methodology) is causality antivirus-centric detection-mediation systems ‘deal’ with the e-threat after it has successfully infiltrated the endpoint and/or network, while EDR focuses on D&M before malware infiltration. From these statements, we can infer the following – the epistemological distinction between EDR and C.A.V.C.D.M. infiltrating your endpoint and/or network). Most ‘modern’ malicious content is specifically engineered to ‘do’ as much damage as possible after establishing a beachhead (i.e. cleaning, quarantining, deletion, etc.) based on how the potentially-malicious file or element behaves while interacting with various processes. In other words, AV engines can only recommend security actions (i.e. It’s undoubtedly a huge leap from the classical detection and remediation methodology, based on post-intrusion behaviorism. Chuvakin reaffirmed the need for a new malware-hunting methodology and tools capable of “detecting and investigating suspicious activities (and traces of such) other problems on host/endpoints.”ĮDR is a strategical approach to malware, emphasizing digital prophylaxis (prevention), screening, and detection over mitigation (‘damage control’). The term ‘EDR’ was first brought to the public attention in 2013 by Anton Chuvakin, Gartner’s Research Director for Technical Professionals, and the head of the Security and Risk Management Strategies team. Deconstructing Endpoint Detection and Response Endpoint Detection and Response (EDR) was born. This game-changing modus operandi would have needed an appropriate retort, on the Defenders’ side. Leaving aside the marketing implications, AVs are simply too ill-equipped to deal with sophisticated, high-end e-threats that are engineered to avoid rudimentary, behavioral-based detection.

In cybersecurity, there’s this well-trodden saying: “antivirus software is not enough”. Viruses and worms have survived their own extinction, taking more virulent forms – ransomware, spyware, adware, fileless malware, and many other ‘ware’ that are bound to make you question your digital life etiquette. However, ‘old’ habits die hard (or don’t). Today, viruses like the Creeper System, The Form, Ghostball, or Father Christmas belong behind a digital display case, being no longer able to harm our systems. It was to be the first mention of a ‘self-replicating computer virus’ in history.e Half a century ago, the Creeper System was released into the wild. We, the digital denizens of the Internet, are faced with such intricately-crafted malware, that makes us ponder whether ‘tis better to abandon all hope and disconnect or search for better ways to protect our endpoints and personal information.
