DISCARDED: Tales From the Threat Research Trenches

Send us fan mail!To move forward, it’s good to take a minute and reflect on what’s happened. Today’s episode focuses on insights from Daniel Blackford and Alexis Dorais-Joncas, both Senior Managers of Threat Research at Proofpoint. This is the first in our two-part series looking at what’s on the horizon for 2024.Reflecting on 2023, they discuss the use of QR codes, major technique shifts from the biggest ecrime and APT actors, and the ongoing problem of ransomware.Looking ahead to 2024, the emphasis goes to the gradual shift of attacks outside corporate-managed infrastructure, leveraging personal email accounts to bypass extensive security measures. On the cybercrime side, there’s a prediction of the continued development of as-a-service models, particularly focusing on traffic distribution services, leading to more modular and challenging-to-attribute attack chains.They also dive into:Threat actor activity during the elections and OlympicsSpecific threat actor groups that caught their attention in 2023, TA473 and TA577Living off the Land conceptsFor more information, check out our website.

Send us fan mail!How can you tell when a website (yes, a website) is compromised? These threats are pretty crafty because they aren't out to target specific individuals; they just wait for folks like you and me to innocently click on compromised websites during our regular browsing. But these threats don't stop at casual browsing. They sneak into emails, social media, search engines, and even web alerts. They're like chameleons, adapting to different situations.Our guest today is Dusty Miller, a Threat Detection Analyst at Proofpoint. He identifies four key groups: SocGholish, RogueRaticate/FakeSG, ZPHP/SmartApeSG, and ClearFake. Each has its own style and tricks, but they all love using that tempting fake browser update ruse.These threats work because they exploit our trust in websites we've visited before. Users tend to trust websites they've visited before, making them more susceptible to clicking on fake browser update prompts.Responding to these threats isn't a walk in the park for defenders. To tackle them effectively, you need to pinpoint which specific threat you're dealing with and respond accordingly. It's like playing a game with multiple rulebooks; you've got to know which one you're up against.TIMESTAMPS[1:45] Fake Browser Opportunities[5:00] Threat Actors Using Malware[9:00] Browser Malware Clusters & Tactics[18:00] Combating Fake Updates[19:00] Naming New Malware[28:00] Why These ThreatsResources mentioned:Dr. Bob Hausmann Episode“Are You Sure Your Browser is Up to Date?...” by Dusty MillerFor more information, check out our website.

Send us fan mail!Oh the days when spam was the only concern for email security!Our guest today is Chris Wakelin, a Senior Threat Researcher at Proofpoint. He recounts the era when email attachments were plain text, and the concept of malicious URLs had yet to become prevalent. Chris was a pioneer in implementing email security measures and recalled introducing Spam Assassin, an early open-source program for spam detection, at his university.Chris emphasized his belief in not shipping emails into a black hole (where emails are never seen by humans and they do not return error but instead directing them to spam folders or rejecting them at the gateway.) He stressed the importance of precision in cybersecurity, a lesson learned from his mathematical background.TIMESTAMPS[5:00] First Spam Filtering Implementation[6:00] Spam Assassin[12:15] Differences between static/dynamic detections and various signatures[14:00] Running the Sandbox[19:00] Naming New Malware[23:50] Best PracticesResources mentioned:LCG Kit BlogTA 558 BlogET Open Rule SetFor more information, check out our website.

Send us fan mail!Live from New York City, it’s your Discarded podcast team at Protect 2023! Joining Selena Larson, is our special guest, John Hultquist, Chief Analyst at Mandiant, now part of Google Cloud.They discuss various cybersecurity threats and activities of nation-states like Russia, China, and North Korea. China stands out as it hasn't executed significant destructive cyberattacks like its peers. Most of China's cyber activity involves intellectual property theft, targeting dissidents, and espionage. However, there's growing concern about their interest in critical infrastructure, particularly in times of geopolitical tension. Russia, on the other hand, has a history of destructive and disruptive attacks, such as those seen in the Middle East and South Korea.They also discuss the role of threat intelligence and information sharing in combating cyber threats, emphasizing the importance of responsible government involvement in providing leads to the cybersecurity community.Of course, the influence of AI in cyber threat creation is also covered, particularly in generating fake media and content.[4:00] China sets themselves apart[8:00] Concerns about cyber enabled kinetic impacts[14:00] Thoughts about Russia and Ukraine[20:00] Techniques that analysts would find helpful[24:00] Target anticipations for 2024Resources mentioned:https://www.mandiant.com/resources/blog/threat-actors-generative-ai-limitedhttps://www.cyberwarcon.com/https://www.goodreads.com/en/book/show/41436213https://www.reuters.com/article/us-france-election-macron-cyber-idUSKBN17Q200https://www.helpnetsecurity.com/2015/07/08/sophisticated-successful-morpho-apt-group-is-after-corporate-data/https://www.microsoft.com/en-us/security/blog/2023/05/24/volt-typhoon-targets-us-critical-infrastructure-with-living-off-the-land-techniques/https://www.mandiant.com/resources/blog/attackers-deploy-new-ics-attack-framework-tritonhttps://podcast.silverado.org/episodes/how-russian-intelligence-operatives-have-attacked-ukraine-in-cyberspace-interview-with-ukrainian-security-service For more information, check out our website.
