Salt Typhoon didn't use some mysterious zero-day exploit to breach major telecom networks. They exploited CVE-2018-0171—a Cisco vulnerability that's been publicly documented for six years. They also targeted Microsoft Exchange flaws that 91% of organizations still haven't patched, despite having patches available for years.
Your security team probably knew about every single vulnerability Salt Typhoon used. They might have even flagged them in risk assessments or mentioned them in security briefings. But knowing about a threat and actually defending against it are completely different skills.
This gap between security awareness and practical defense capability is exactly why sophisticated attackers like Salt Typhoon continue to succeed. They understand something most organizations don't: having a team that can read CVE reports doesn't mean you have a team that can stop real attacks.
What Salt Typhoon Actually Did
Salt Typhoon's attack methods weren't particularly innovative—they were systematic. They exploited CVE-2018-0171, a six-year-old authentication bypass vulnerability in Cisco Smart Install that allows attackers to execute commands remotely without credentials. They also targeted CVE-2023-46805 and CVE-2024-21887 in Ivanti Connect Secure VPN systems—flaws that let attackers bypass authentication entirely and chain together for remote code execution.
The group frequently exploited Microsoft Exchange vulnerabilities like CVE-2021-26855, part of the ProxyLogon attack chain that enables attackers to authenticate as Exchange servers and steal email data. In many cases, they didn't even need to exploit vulnerabilities at all—they simply used stolen credentials to walk through the front door.
Once inside networks, Salt Typhoon used "living off the land" tactics with PowerShell and Windows Management Instrumentation (WMIC)—administrative tools that come pre-installed on Windows systems. This approach helped them blend in with normal IT activity while conducting reconnaissance, stealing more credentials, and moving laterally through networks.
What made Salt Typhoon effective wasn't sophisticated technology, but their systematic approach to chaining these known vulnerabilities together. They understood how to exploit trust relationships between network devices and leverage compromised systems to access high-value targets like government communications and law enforcement wiretapping systems.
The uncomfortable reality is that everything Salt Typhoon did was preventable using existing security controls and proper system architecture.

The Knowledge Gap That's Costing Organizations
Your security team can probably recite CVE numbers from memory and explain exactly how each Salt Typhoon vulnerability works. But can they design network architectures that actually contain these attacks? There's a massive difference between understanding that CVE-2018-0171 allows remote code execution and knowing how to segment your Cisco devices so that compromise doesn't lead to lateral movement across your entire infrastructure.
Most security training focuses on threat identification rather than defensive implementation. Your team learns to spot vulnerabilities during penetration tests, but they don't learn how to build systems that fail safely when those vulnerabilities are inevitably exploited. They can tell you that Ivanti Connect Secure has authentication bypass flaws, but do they know how to architect VPN access controls that limit blast radius when that bypass occurs?
This knowledge gap becomes critical when attackers start chaining vulnerabilities systematically. Salt Typhoon didn't just exploit individual flaws—they leveraged each compromised system as a stepping stone to higher-value targets. Your team might understand each vulnerability in isolation, but understanding how to design defenses that break these attack chains requires a completely different skill set.
The result is organizations with security-aware teams that remain fundamentally vulnerable to systematic attacks. Knowledge without practical defensive capability is just expensive documentation of your weaknesses.
Why "Awareness" Training Fails in Real Attacks
These weren't sophisticated attacks—they were basic techniques applied systematically across specific environments. Salt Typhoon succeeded because they understood the operational realities of telecom networks: how routing protocols create trust relationships, where wiretapping systems connect to core infrastructure, and which administrative accounts provide the broadest network access.
Your organization likely has similar exposure right now. You probably have network devices running older firmware, VPN appliances with known authentication issues, and administrative credentials vulnerable to social engineering. The question isn't whether these weaknesses exist—it's whether your team can actually prevent attackers from exploiting them in your specific environment.
This is why generic security training often fails in practice. Knowing that credential stuffing is a threat doesn't help when you need to decide which service accounts to disable during an active breach without breaking critical business processes.
The Real-World Application Problem
These weren't sophisticated attacks—they were basic techniques applied systematically across specific environments. Salt Typhoon used six-year-old Cisco vulnerabilities and stolen passwords, yet they successfully compromised telecommunications infrastructure that handles sensitive government communications. The sophistication wasn't in their tools; it was in their understanding of how telecom networks actually operate.
Your organization likely has similar exposure right now. You probably have network devices running older firmware, VPN appliances with known authentication issues, and administrative credentials that could be compromised through social engineering or password reuse. The question isn't whether these weaknesses exist—it's whether your team can actually prevent attackers from exploiting them in your specific environment.
Salt Typhoon succeeded because they understood the operational realities of telecom networks: how routing protocols create trust relationships, where CALEA wiretapping systems connect to core infrastructure, and which administrative accounts provide the broadest network access. Your security team might know these vulnerabilities exist in theory, but do they understand how they manifest in your particular network topology?
This is why generic security training often fails in practice. Knowing that credential stuffing is a threat doesn't help when you need to decide which service accounts to disable during an active breach without breaking critical business processes. Real defense requires understanding both the attack techniques and your specific operational environment.

Building Teams That Actually Defend
This is exactly why professional cybersecurity certifications have become so critical for organizations facing sophisticated threats. When Salt Typhoon strikes your industry, you need team members who don't just recognize the attack—they know exactly how to stop it before it spreads through your network.
The problem with most security training is that it focuses on awareness rather than capability. Professional certifications, however, are designed to bridge that gap by teaching practical defensive skills that work under real-world pressure. They move beyond theoretical knowledge to hands-on application of security principles.
For instance, Security+ (CompTIA Security+) certification builds the foundational skills your team needs to understand how attacks work and how to implement basic security controls effectively. Security+ certified professionals grasp the fundamentals of network defense, risk assessment, and incident response that prevent simple vulnerabilities from becoming major breaches.
If you're working with cloud infrastructure, the Certified Cloud Security Professional (CCSP) certification becomes essential. CCSP-certified professionals learn how to architect cloud environments that isolate compromised workloads, design identity and access management systems that prevent credential-based lateral movement, and implement monitoring that detects systematic exploitation patterns across hybrid infrastructure.
For those managing security teams, both the Certified Information Security Manager (CISM) and Certified Information Systems Security Professional (CISSP) certifications provide the leadership and architectural skills needed to build resilient security programs. CISSP focuses on designing defensive architectures that contain attacks, while CISM emphasizes the governance and risk management aspects of building security programs that can withstand systematic threats like Salt Typhoon.
These certifications emphasize practical application over theoretical knowledge, developing the skills to translate security awareness into operational security capability.
