# Summary The CoreDNS etcd plugin contains a TTL confusion vulnerability where lease IDs are incorrectly used as TTL values, enabling cache pinning for very long periods. This can effectively cause a denial of service for DNS updates/changes to affected services. # Details In `plugin/etcd/etcd.go`, the `TTL()` function casts the 64-bit etcd lease ID to a uint32 and uses it as the TTL: ```go func (e *Etcd) TTL(kv *mvccpb.KeyValue, serv *msg.Service) uint32 { etcdTTL := uint32(kv.Lease) // BUG: Lease ID != TTL duration // ... rest of function uses etcdTTL as actual TTL } ``` Lease IDs are identifiers, not durations. Large lease IDs can produce very large TTLs after truncation, causing downstream resolvers and clients to cache answers for years. This enables cache pinning attacks, such as: 1. Attacker has etcd write access (compromised service account, misconfigured RBAC/TLS, exposed etcd, insider). 2. Attacker writes/updates a key and attaches any lease (the actual lease ...

Cybersecurity researchers have disclosed details of a phishing campaign that delivers a stealthy banking malware-turned-remote access trojan called MostereRAT. The phishing attack incorporates a number of advanced evasion techniques to gain complete control over compromised systems, siphon sensitive data, and extend its functionality by serving secondary plugins, Fortinet FortiGuard Labs said.

# Summary pREST provides a simple way for users to expose access their database via a REST-full API. The project is implemented using the Go programming language and is designed to expose access to Postgres database tables. During an independent review of the project, Doyensec engineers found that SQL injection is a systemic problem in the current implementation (version `v2.0.0-rc2`). Even though there are several instances of attempts to sanitize user input and mitigate injection attempts, we have found that on most code-paths, the protection is faulty or non-existent. ## Core Endpoints The main functionality providing REST operations on the data stored in the Postgres database is exposed via the following endpoints: - `GET /{database}/{schema}/{table}` - `POST /{database}/{schema}/{table}` - `PUT|PATCH /{database}/{schema}/{table}` - `DELETE /{database}/{schema}/{table}` Handlers for the above endpoints execute very similar logic. At a high-level they: 1. Perform authenticati...

Cybersecurity never slows down. Every week brings new threats, new vulnerabilities, and new lessons for defenders. For security and IT teams, the challenge is not just keeping up with the news—it’s knowing which risks matter most right now. That’s what this digest is here for: a clear, simple briefing to help you focus where it counts. This week, one story stands out above the rest: the

When Attackers Get Hired: Today’s New Identity Crisis What if the star engineer you just hired isn’t actually an employee, but an attacker in disguise? This isn’t phishing; it’s infiltration by onboarding. Meet “Jordan from Colorado,” who has a strong resume, convincing references, a clean background check, even a digital footprint that checks out. On day one, Jordan logs into email and attends

### Impact When establishing a TLS session using `fs2-io` on the JVM using the `fs2.io.net.tls` package, if one side of the connection shuts down write while the peer side is awaiting more data to progress the TLS handshake, the peer side will spin loop on the socket read, fully utilizing a CPU. This CPU is consumed until the overall connection is closed. This could be used as a denial of service attack on an fs2-io powered server -- for example, by opening many connections and putting them in a half-shutdown state. Note: this issue impacts ember backed http4s servers with HTTPS as a result of ember using fs2's TLS support. ### Patches Fixed in fs2 3.12.2 and 3.13.0-M7. ### Workarounds No workarounds. ### For more information If you have any questions or comments about this advisory: [Open an issue.](https://github.com/typelevel/fs2/issues/new/choose) Contact the [Typelevel Security Team](https://github.com/typelevel/.github/blob/main/SECURITY.md).

Cybersecurity researchers have flagged a Ukrainian IP network for engaging in massive brute-force and password spraying campaigns targeting SSL VPN and RDP devices between June and July 2025. The activity originated from a Ukraine-based autonomous system FDN3 (AS211736), per French cybersecurity company Intrinsec. "We believe with a high level of confidence that FDN3 is part of a wider abusive
