This presentation will provide an overview of common SQL Server discovery, privilege escalation, persistence, and data targeting techniques. Techniques will be shared for escalating privileges on SQL Server and associated Active Directory domains. Finally I’ll show how PowerShell automation can be used to execute the SQL Server attacks on scale with PowerUpSQL. All scripts demonstrated during the presentation are available on GitHub. This should be useful to penetration testers and system administrators trying to gain a better understanding of their SQL Server attack surface and how it can be exploited.

Once inside your network, most cyber-attacks go sideways. They progressively move deeper into the network, laterally compromising other systems as they search for key assets and data. Would you spot this lateral movement on your enterprise network? In this training session, we review the various techniques attackers use to spread through a network, which data sets you can use to reliably find them, and how data science techniques can be used to help automate the detection of lateral movement.

Understanding Fileless (or Non-Malware) Attacks and How to Stop Them

CrowdStrike

How adversaries use fileless attacks to evade your security and what you can do about it Standard security solutions have continued to improve in their ability to detect and block malware and cyberattacks. This has forced cybercriminals to employ stealthier methods of evading legacy security to achieve success, including launching fileless attacks, where no executable file is written to disk. Download this presentation provided by CrowdStrike security experts to learn why so many of today’s adversaries are abandoning yesterday’s malware and relying on an evolving array of fileless exploits. You’ll learn how fileless attacks are conceived and executed and why they are successfully evading the standard security measures employed by most organizations. You’ll also receive guidance on the best practices for defending your organization against these stealthy, damaging attacks. The following presentation includes: --How a fileless attack is executed — see how an end-to-end attack unfolds --Why fileless attacks are having so much success evading legacy security solutions --How you can protect your organization from being victimized by a fileless attack, including the security technologies and policies that are most effective

Regardless on how sophisticated your framework is, how many layers of firewalls and mitigation techniques that are put in place, there's a common weakness that often gets overlooked: the insecure direct object reference. The flaw exist everywhere: WordPress with username enumeration issues. Twitter where remote attackers could delete credit cards for the ad service and to OculusVR with a horizontal privilege escalation vulnerability which got disclosed recently.

Threat Intelligence with Open Source Tools - Cornerstones of Trust 2014

Santiago Bassett

Threat Intelligence has become increasingly important as the number and severity of threats is growing continuously. We live in an era where our prevention technologies are not enough anymore, antivirus products fail to detect new or sophisticated pieces of malware, our firewalls and perimeter defenses are easily bypassed and the attacker’s techniques are growing in complexity. In this new landscape, sharing threat intelligence has become a key component to mitigate cyber-attacks. In this session we will define what Threat Intelligence is and discuss how to collect and integrate threat intelligence from public sources. In addition, we’ll demonstrate how to build your own Threat Intelligence data using Open Source tools such as sandboxes, honeypots, sinkholes and other publicly available tools. The industry’s reticence to share information about attack vectors gives the adversary a huge advantage. Using Threat Intelligence we can reduce this advantage and enable preventative response. We will guide you through the different standards (OpenIOC, STIX, MAEC, OTX, IODEF…) to describe and share cyber intelligence, as well as Open Source Frameworks such as CIF (Collective Intelligence Framework) that allows you to combine different threat sources. One of the biggest problems with Threat Intelligence is finding out how to take advantage of the data you have to actually improve the detection/prevention capabilities in your environment. We will describe how to leverage Threat Intelligence to detect threats and provide defenses, and we will focus on how to use Open Source Tools (Suricata, OSSIM, OSSEC, Bro, Yara…) to get the most of your Threat Intelligence.

王峰不太愿意提子允和周晨晨的那种关系，结果还是触碰了，唉，别人的情网也法力无边。但事已至此，不好过分，作为好朋友，关键的时候怎么也该撑场子。那去就是，为了弟兄哪怕被王秀粘上四辈子也心甘，但你注意，我的灯泡很亮，菲利普2500瓦，够亮吧？我是它两个亮。没事，我本身光明正大，而且身上还背着发电机的。你老弟可要当心，别因为短路把身体给烧糊了。没事，那我就可以在烈火中永生了。《Y滋味》显文具店里中午放学后，四人汇聚到校门口边上的文具店里。显然两位女士没想到王峰会来，吃了一小惊。这又给了王秀展示厉害的机会，尽管香港六合彩平日与王峰不大熟，此时却搞得像三十年的老相识。哟，你也来啦？好啊，人多热闹。说完侧过脸坏笑着看子允，只不过赵大财主又要多破费了。子允跟王峰相视一笑，对香港六合彩说，如果钱不够，留下你给老板的儿子做童养媳。去，去，去，把晨晨留下差不多。哎，正经点儿，去哪吃饭？王秀向每个人扫一遍，一句话问了三个人。去麦当劳。王峰说。麦当劳吧。周晨晨跟道。我随便。子允的声音显得很突出。三个人很配合，被王秀这么一问，同时说出自己的想法。哎，香港六合彩两搞什么？回答得这么整齐？赵子允你可要小心了，王峰和晨晨很默契，强有力的竞争对手喔。王秀这句话很具煽动性，把王峰和晨晨弄得满脸通红。子允被牵其中，也红着脸不知看哪好。王秀，你说什么呀。周晨晨扯着香港六合彩的衣角小声责怪。就是，你这是挑拨香港六合彩兄弟感情，小心吃饭时王峰送你蹲厕所。子允趁机乱中添乱。打破混乱最好的方法就是让事情更混乱，子允一直这么认为。好，我同意，让香港六合彩吃不了兜着走。王峰扬起还在红着的脸，而且是在厕所吃不了兜着走。谈到厕所，女人最不好接招，王秀毫无还手之力，跟着傻笑。一般来说，一对一开损的时候不容易分出伯仲，如果二对一，那个一可就难有招架之力。假使三对一，那一的日子估计只有撕下脸自嘲一番才能逃过此劫。好了，既然两人都要去麦当劳，那香港六合彩抓紧时间吧，中午时间可不充裕。显然，子允对王秀的话很不在心，惦记着找机会用三对一的架式让香港六合彩乖巧一下嘴。到了麦当劳，子允和王峰主动担当起点餐任务，问清两位女生的需要后一起来到柜台排队点餐。周晨晨选了个靠窗的四人位子，然后单手托腮望着窗外卖红薯的老太太发呆。王秀则叽叽喳喳说终于敲诈到子允了。这头，子允正窃笑着王秀嘴大胃小，原以为香港六合彩真会让自己大把挥银，想不到香港六合彩只要了两对(又鸟)翅和一包大薯条，连饮料都是子允过意不去死活让香港六合彩要的。

The State of Incident Response - INFOGRAPHIC

AlienVault

Incident Response (IR) teams are designed to detect, investigate and, when necessary, perform remediation in the event of a critical incident. The results of the 2015 SANS Incident Response Survey provides a picture of what IR teams are up against today—the types of attacks they see, what defenses they have in place to detect and respond to these threats, and their perceived effectiveness and obstacles to incident handling. Some key challenges reported by responders to the survey were: 66% cited a skills shortage as being an impediment to effective IR: 54% cited budgetary shortages for tools and technology 45% noted lack of visibility into system or domain events 41% noted a lack of procedural reviews and practice 37% have trouble distinguishing malicious events from nonevents Do these challenges sound familiar? Download the full survey to learn more about how other organizations are approaching incident response, along with best practices and advice. Visit http://ow.ly/R3Cr0

How Malware Works

AlienVault

With malware accounting for at least 40% of all breaches, knowing how malware works can be an extremely valuable asset in your threat detection cache – especially for the incident responder. According to Verizon’s 2013 Data Breach Investigations Report, “Malware and hacking still rank as the most common [threat] actions”. In general, malware can range from being simple annoyances like pop-up advertising to causing serious damage like stealing passwords and data or infecting other machines on the network. Malware is as old as software itself and although there are new types of malware constantly under development, they generally fall into a few broad categories. Check out this SlideShare to learn how malware works, and what we believe are the most common types of malware you should be prepared for. By learning how malware works and recognizing its different types, you’ll understand: - How they find their way into your network - How attackers control them remotely - How they use your systems for nefarious purposes - And most importantly, the security controls you need to effectively defend against and detect malware infections. (Hint: you need more than antivirus!)

AWS Security Best Practices for Effective Threat Detection & Response

AlienVault

In this SlideShare, we’ll share the AWS Security Best Practices for securing AWS environments, as well as some of the trends our research has shown with regard to attacks on those environments. We'll also introduce the key capabilities needed for a modern threat detection & incident response program customized for AWS, and other AWS Security Best Practices including: -Asset Discovery - creating an inventory of running instances -Vulnerability Assessment - conducting scans to assess exposure to attack, and prioritize risks -Change Management - detect changes in your AWS environment and insecure network access control configurations -S3 & ELB Access Log Monitoring - Monitor access logs of hosted content and data directed at your instance -CloudTrail Monitoring and Alerting - Monitor the CloudTrail service for abnormal behavior -Windows Event Monitoring - Analyze system level behavior to detect advanced threats With more IT environments moving data and applications to AWS, the motivation for hackers to target AWS environments is also increasing. We believe these AWS Security Best Practices will be a valuable addition to every security practitioner’s playbook. We'll finish up with a demo of NEW AlienVault USM for AWS, which delivers all of the above capabilities, plus log management & event correlation to help you detect threats quickly and comply with regulatory requirements.

Alien vault sans cyber threat intelligence

AlienVault

Over the last several years, we have seen that attackers are innovating much faster than defenders are. This trend is steering many companies to look towards cyber threat intelligence (CTI) to help them navigate today’s threatening landscape. SANS conducted a survey this year to explore who is using cyber threat intelligence and how they are using it. The survey collected responses from 326 IT professionals working in a variety of industries, in all sizes and from many different regions. 69% of the respondents reported implementing CTI to some extent, with only 16% planning not to pursue CTI in their environments. Which side of this percentage do you fall into? The infographic below provides some of the key questions to ask when getting started with threat intelligence, along with data from the SANS survey to show you how others are using threat intelligence.

Demo how to detect ransomware with alien vault usm_gg

AlienVault

By now you've probably heard about new ransomware threats like CryptoWall, which encrypts your data and demands payment to unlock it. These threats are delivered via malicious email attachments or websites, and once CryptoWall executes and connects to an external command and control server, it starts to encrypt files throughout your network. Therefore, spotting infections quickly can limit the damage. Don’t fall victim to ransomware! AlienVault USM uses several built-in security controls working in unison to detect ransomware like CryptoWall, usually as soon as it attempts to connect to the hackers’ command and control server. How does it all work? Join us for a live demo that will show how AlienVault USM detects these threats quickly, saving you valuable clean up time by limiting the damage from the attack. You'll learn: How AlienVault USM detects communications with the command and control server How the behavior is correlated with other signs of trouble to alert you of the threat Immediate steps you need to take to stop the threat and limit the damage

Neuro-symbolic is not enough, we need neuro-*semantic*

Frank van Harmelen

Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”. All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management. The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM). Speakers: Bob Boule Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work. He comes with around 20 years of solution engineering experience in application security, software continuous delivery, and SaaS platforms. He is known for his dynamic presentations in CI/CD and application security integrated in software delivery lifecycle. Gopinath Rebala Gopinath Rebala is the CTO of OpsMx, where he has overall responsibility for the machine learning and data processing architectures for Secure Software Delivery. Gopi also has a strong connection with our customers, leading design and architecture for strategic implementations. Gopi is a frequent speaker and well-known leader in continuous delivery and integrating security into software delivery.
