セキュアアクセスサービスエッジ（SASE）の理解

09/19/2023 Secure access service edge (SASE – pronounced “sassy”) is a modern architectural framework that combines network security and wide area networking (WAN) capabilities into a unified cloud-based service. It is designed to provide secure and optimized access to network resources for users, regardless of their location or the devices they use. Secure access service edge represents a shift from the traditional approach of backhauling network traffic to centralized data centers for security inspection. Instead, it adopts a cloud-native model where security services are delivered from the cloud and applied directly at the network edge, close to the user and the resources they are accessing. Acronyms to Know Before we get […]

秘密の保護：コード難読化技術の洞察

06/29/2023 Once a threat actor gains access to a network or tricks a user into downloading a malicious attachment. The next step is to download their payload, this could be a toolset or malware. Code obfuscation has become an important step for threat actors to accomplish this task.  Whether it is a webshell, or a utility program code obfuscation is often utilized during part of the command execution phase.  In this post we are going to review a recently observed phishing attack where the threat actor delivered the remote access tool known as “asyncrat”   through several different variations of code obfuscation.  As we have all seen many many times the […]

NetWitness OrchestratorでSecOpsを効率化する方法

06/07/2023 Security operations (SecOps) teams are battling a complex and ever-evolving challenge: Keeping an organization secure against cyberattacks from faceless, remote users in a technologically advanced world. With the rise of threats, new technologies, and increasingly sophisticated scams, staying ahead of the bad guys is more important than ever. That’s where security orchestration, automation, and response (SOAR) platform comes in to make your SecOps team more effective against attacks. A security orchestration, automation, and response (SOAR) platform system automates what would be a manual process of identifying cyberattacks and making it easier to respond to those attacks. However, not all SOAR solutions are created equal. NetWitness Orchestrator, a security orchestration automation […]

ランサムウェアの標的としてのUSMSと法執行機関への広範な影響

03/02/2023   The mission of the U.S. Marshals Service (USMS) is “to enforce federal laws and provide support to virtually all elements of the federal justice system” through multiple disciplines. Its law enforcement (LE) focus, reach and scope make this week’s report of a recent cyberattack involving both ransomware and data exfiltration especially concerning. While this news is fresh, and the incident ongoing, it’s a good time for us all to reflect on why LE entities can be especially attractive targets to bad actors. As with all important things in life, it always pays off to understand motivations and incentives, and how they can drive behaviors and actions. Low-hanging fruit of […]

ハイブのテイクダウンに関する5つの考察

02/03/2023   The takedown of the Hive ransomware-as-a-service group has been in the news over the past week, and it’s good news indeed. Beyond the obvious benefits of disrupting this criminal enterprise, there are some other discrete takeaways which are particularly important to note. Cross-jurisdictional cooperation and coordination can be done, and done effectively. Any of us who have served on committees know about Parkinson’s Law, which correlates a group’s size to the amount of time needed to accomplish its goals: the bigger the group, the longer the time taken, even without a change in scope. The fact that this global law enforcement effort was a success is even more impressive […]

犠牲を払え：脅威となる行為者のコストを引き上げて抑止する方法

09/30/2022 Introduction Many years ago, I spoke at a @suitsandspooks panel in Washington, D.C. with some of the cybersecurity industry’s best and brightest minds. One of the topics addressed was the concept of active defense strategy in the commercial (private sector) world versus the public world. In those days the idea of ‘hacking back’ against a hostile, adversarial threat actor or group was discussed frequently, with some organizations and their leaders taking a more vocal stance (in both public and private sectors). The panel was fantastic: Dmitri Alperovitch (CrowdStrike), Greg Hoglund, Jeff Carr, me, and moderated by Anup Ghosh. A smart group of guys all with strong opinions on the subject […]

UPDATE：ロシアとウクライナの紛争について我々が知っていることと、サイバーセキュリティ能力をどのように準備すべきか

03/25/2022 UPDATED March 25, 2022: The Biden Administration released a statement on March 21 urging companies to strengthen their cybersecurity capabilities and protections in the face of potentially damaging cyber activity perpetrated by threat actors as part of the ongoing conflict. The Administration also urged organizations to execute a number of best practices for bolstering cyber defense capabilities. Additionally, the Cybersecurity & Infrastructure Security Agency (CISA) website’s Shields Up page is an excellent resource to help prepare for disruptive cyber incidents. The NetWitness Incident Response team is available to assist organizations with enacting these recommendations, as well as several other services, and does not require organizations to be existing NetWitness customers […]

あなたのコラボレーションツールはハッカーフレンドリー？

11/19/2021 It’s back to the future. Companies and their employees are slowly returning to in-person work, with many organizations maintaining their hybrid workforce model. And this shift to remote work has resulted in an increasing reliance on web-based collaborative tools. In fact, a Gartner study found that usage of collaboration tools has nearly doubled over the last two years, going from 55% to 80% among workers. Many of these tools, such as Microsoft Teams, Slack, and Zoom, have been integral components of organizational productivity for years, but the change to a highly remote workforce has more deeply embedded these types of applications into business operating procedures. Realizing this opportunity, hackers and […]

検証可能なクレデンシャル：次のウェブにおける信頼の鍵

07/14/2021 RSA once again secures the open web In 1994 the World Wide Web was at a crossroads. The technology that today we simply call “the web,” invented five years earlier by Tim Berners-Lee, was poised to become the de facto interface to the internet. Its document-based, human-centric, point-and-click model was wildly popular among the technologists of the day, and was beginning to see rapid uptake among the broader population of desktop software users. But something was missing: trust. Because the web was inherently open, any use case requiring trust between parties was impossible. All web traffic at that point traveled in clear text where it could be intercepted, and potentially […]
