For the latest WannaCry information as it relates to Trend Micro products, please read this support article. The WannaCry ransomware variant of May has been engineered to take advantage of the most common security challenges facing large organizations today.

Check out this NYT post, they made a really cool time based map with my data https: One of the biggest challenges facing the security community today is effectively communicating cybersecurity within the larger context of the business.

A common refrain in the security community is that patching is your first line of defence. But the reason can be boiled down roughly to the fact that IT is critical to the business.

Interruptions are frustrating and costly. The constant barrage of updates is tiring and gets in the way of work. Making matters worse is the unpredictable nature of application behaviour post-patch. At this time, the primary motivator was patch quality. Patches can change the landscape rendering critical business applications unusable until they too can be patched. This cycle is why most businesses stick to traditional practices of testing patches, which significantly delays their deployment.

Investing in automated testing to reduce deployment time is expensive and a difficult cost to justify given the long list of areas that need attention within the IT infrastructure. This unrelenting river of patches makes it difficult for organizations to truly evaluate the risks and challenges of deploying critical security patches.

The argument around patching assumes—of course—that a patch is actually available to resolve the issue. This is the zero-day. While the threat of zero-days is real, long patch cycles mean the day, day, and the forever-day are far more likely to be used in an attack. The Verizon Data Breach Investigations Report consistently highlights how many organizations are breached using exploits of patchable vulnerabilities.

The WannaCry campaign used a vulnerability that was publicly known for 59 days. Making matters worse, MS was only patched on supported platforms. A position that Microsoft has since reversed and issued a patch for all affected platforms kudos to them for making that call.

There are third party security solutions some from Trend Micro that can help address the issue, these legacy systems are a weight on forward progress. Security teams need to help the rest of the IT teams explain the need to invest in updating legacy infrastructure. After all, the business processes have adapted to these systems and from a workflow process, they are reliable.

The challenge is quantifying the risk they pose maintenance and security-wise or at least putting this risk in the proper perspective in order to make an informed business decision. All too frequently, vulnerabilities are flagged as critical. This is where organizations tend to falter. In theory, you should take the cost of downtime when deploying the patch and compare it to the cost of a breach. This is where it gets really complicated and highly individualized. The debate on how to properly evaluate this decision rages on in the IT community, but specific to WannaCry, the equation was actually pretty straight forward.

Microsoft issued MS in March, and flagged it as critical. A month later, there was a very high profile and very public data dump that contained an easy to understand and execute exploit for the vulnerabilities patched by MS At this point, the security team can guarantee that their organization will see attacks taking advantage of this vulnerability.

That puts the probability of attack at percent. Un-patchable systems still need to be protected. With WannaCry, all affected systems are patchable now—again, thanks to a generous move by Microsoft.

This is where mitigations come into play. These mitigations also buy time for patches to be deployed. WannaCry is a solid example of a new variant that caused significant damage before traditional anti-malware scanning could be implemented.

This is where machine learning models and behavioural analysis running on the endpoint is critical. These techniques provide continuous and immediate protection for new threats. In the case of WannaCry, systems with this type of endpoint protection were not impacted. After deeper analysis by the security community, traditional controls were able to detect and prevent the latest variant of WannaCry from taking root. When in place, strong network controls like intrusion prevention were able to block WannaCry from spreading indiscriminately throughout corporate networks.

This is another argument for microsegmentation within the network. Finally, phishing emails continue to be the most effective method of malware distribution—even though it might not be the case with WannaCry.

Aggressively scanning emails for threats and implementing strong web gateways are a must. Patching is a critical issue and it needs the entire IT organization working with the rest of the business to be effective. Year after year, the majority of attacks take advantage of patchable vulnerabilities. This means that most cyberattacks are currently preventable. Rapid patching combined with reasonable security controls for mitigating new and existing threats are the one-two punch your organization needs to reduce its risk of operating in the digital world.

While the problem and solutions are technical in nature, getting the work done starts with communications. How are you tackling these issues in your organizations?
