On the Fuzzing Hook - Exploring Deeper Program States

Coverage-guided fuzzers, like Jazzer, maximize the amount of executed code during fuzzing. This has proven to produce interesting findings deep inside the codebase. Only checking validation rules on the first application layer isn’t providing great benefits, whereas verifying logic in and interactions of deeply embedded components is. To extend the amount of covered code, the fuzzer tries to mutate its input in such a way that it passes existing checks and reaches yet unknown code paths.

How and why you should secure APIs

APIs are a crucial tool in today’s business environment. Allowing applications to interact and exchange data and services means that companies can provide an ever-greater range of features and functionalities to their clients quickly and easily. So, it is no wonder that a quarter of businesses report that APIs account for at least 10% of their total revenue - a number that will only increase in coming years.

CVE-2022-23648: Kubernetes Container Escape Using Containerd CRI Plugin and Mitigation

CVE-2022-23648, reported by Google’s Project Zero in November 2021, is a Kubernetes runtime vulnerability found in Containerd, a popular Kubernetes runtime. It lies in Containerd’s CRI plugin that handles OCI image specs containing “Volumes.” The attacker can add Volume containing path traversal to the image and use it to copy arbitrary files from the host to container mounted path. The vulnerability was reported by Felix Wilhelm on Nov.

Compromising Read-Only Containers with Fileless Malware

Containers provide a number of security features that are not simply available on a normal host. One of those is the ability to make the container’s root filesystem read-only. By making the file system unable to be altered, it prevents an attacker from writing their malware executable to disk. Most attacks rely on writing files in order to work, but sophisticated cases use fileless malware as part of their malicious behavior.

Ransomware Response and Remediation With a Data Observability Engine for Data Security

Ransomware can be expensive—in 2021, the average cost of a ransomware attack was $4.62million, and that doesn’t include the ransom itself. Beyond financial costs, the cost of time, data, and brand reputation can also be astronomical. According to the IST Ransomware Task Force, the average downtime can be 21 days, with full recovery taking on average 287 days from the initial ransomware incident response. And cyber criminals are getting more sophisticated every year.

Ignoring vulnerabilities with Snyk

Ignore a vulnerability? That sounds like a paradox. Why would anyone want to ignore a vulnerability? While ignoring security issues should not be your default practice, it is still sometimes necessary. Development and security teams today face vulnerability backlogs consisting of thousands of issues. To maintain rapid development, they must be able to effectively prioritize their work.

Wi-Fi and its relationship with the zero-trust model

Zero-trust network architecture (ZTNA) provides a holistic view of business cybersecurity that secures your applications and environment when accessed by any user, device, or location. A comprehensive zero-trust model enables you to mitigate, detect and respond to threats.
