A new distributed denial-of-service (DDoS) botnet known as Kimwolf has enlisted a massive army of no less than 1.8 million infected devices comprising Android-based TVs, set-top boxes, and tablets, and may be associated with another botnet known as AISURU, according to findings from QiAnXin XLab. "Kimwolf is a botnet compiled using the NDK [Native Development Kit]," the company said in a report

SoundCloud confirms a breach affecting an estimated 20% of users, resulting in stolen email addresses. The company is dealing with follow-up DoS attacks by unnamed attackers while media reports allege involvement of ShinyHunters.

Several builtin functions in Expr, including `flatten`, `min`, `max`, `mean`, and `median`, perform recursive traversal over user-provided data structures without enforcing a maximum recursion depth. If the evaluation environment contains **deeply nested** or **cyclic** data structures, these functions may recurse indefinitely until exceed the Go runtime stack limit. This results in a **stack overflow panic**, causing the host application to crash. While exploitability depends on whether an attacker can influence or inject cyclic or pathologically deep data into the evaluation environment, this behavior represents a denial-of-service (DoS) risk and affects overall library robustness. Instead of returning a recoverable evaluation error, the process may terminate unexpectedly. ### Impact In affected versions, evaluation of expressions that invoke certain builtin functions on untrusted or insufficiently validated data structures can lead to a **process-level crash** due to stack exhau...

### Description A nil pointer dereference vulnerability was discovered in the SIPGO library's `NewResponseFromRequest` function that affects all normal SIP operations. The vulnerability allows remote attackers to crash any SIP application by sending a single malformed SIP request without a To header. The vulnerability occurs when SIP message parsing succeeds for a request missing the To header, but the response creation code assumes the To header exists without proper nil checks. This affects routine operations like call setup, authentication, and message handling - not just error cases. > Note: This vulnerability affects all SIP applications using the sipgo library, not just specific configurations or edge cases, as long as they make use of the `NewResponseFromRequest` function. ### Technical details The vulnerability is located in `/sip/response.go` at line 242 in the `NewResponseFromRequest` function: ```go if _, ok := res.To().Params["tag"]; !ok { uuid, _ := uuid.NewRando...

> Note that this vulnerability is only present when using `experimental_caller` / `experimental_nextAppDirCaller`. ## Summary A Prototype Pollution vulnerability exists in `@trpc/server`'s `formDataToObject` function, which is used by the Next.js App Router adapter. An attacker can pollute `Object.prototype` by submitting specially crafted FormData field names, potentially leading to authorization bypass, denial of service, or other security impacts. ## Affected Versions - **Package:** `@trpc/server` - **Affected Versions:** >=10.27.0 - **Vulnerable Component:** `formDataToObject()` in `src/unstable-core-do-not-import/http/formDataToObject.ts` ## Vulnerability Details ### Root Cause The `set()` function in `formDataToObject.ts` recursively processes FormData field names containing bracket/dot notation (e.g., `user[name]`, `user.address.city`) to create nested objects. However, it does **not** validate or sanitize dangerous keys like `__proto__`, `constructor`, or `prototype`. #...

We compared three incidents that surfaced today to show why the impact of a breach depends less on who was hit and more on what was taken.

A critical vulnerability (CVE-2025-34352) found by XM Cyber in the JumpCloud Remote Assist for Windows agent allows local users to gain full SYSTEM privileges. Businesses must update to version 0.317.0 or later immediately to patch the high-severity flaw.
