Almost Half of Malware Samples Communicate Direct to IP

Analysis of 4 million dynamic malware reports reveals that 45.32% of malware samples with command-and-control activity establish direct-to-IP (D2IP) connections, bypassing DNS entirely and evading DNS-based security defenses. D2IP traffic accounts for 23.17% of all C2 connection attempts. This behavior is observed across diverse threats including Phorpiex ransomware droppers using hard-coded IP addresses, persistent data exfiltration campaigns employing obfuscated HTTP GET requests, SectopRAT targeting educational institutions with in-browser proxy capabilities, and IoT botnets like Mozi and Boatnet propagating through P2P networks. The research introduces zero trust IP (ZT-IP), a network-level enforcement approach that verifies whether outbound connection destinations were previously sanctioned by DNS responses, effectively blocking malicious D2IP communications that traditional DNS-based security controls cannot detect.

WhatsApp account takeover scam asks you to "vote for my friend"

A sophisticated scam is spreading through WhatsApp that exploits the platform's legitimate 'Linked devices' feature to take over user accounts. Attackers compromise existing accounts and send messages to contacts asking them to vote for a friend or relative in various online contests. When victims click the provided link, they are redirected through pages appearing to be WhatsApp-related, often using the legitimate wa.me domain. The attack tricks users into authorizing a new linked session, granting attackers full access to read messages, send messages as the victim, and access contacts. The scam is particularly effective because it comes from known contacts and relies on trust and quick reactions. Once compromised, attackers can continue the scam by messaging the victim's contacts, creating a chain of account takeovers without triggering traditional security alerts.

Since I picked up programming at 8yo with BASIC, I've been a bit of a language polyglot. Over the years I've coded in C, Python, Perl, Shell, more flavors of Assembly than I care to admit, occasionally C++, Go, Java and JavaScript, and heck, even PowerShell.

Then a couple of years ago I started taking #Rust seriously, and I basically haven't touched anything else since.

Anyway, here's where that obsession led. This summer's #GitHub tour, part two:

My vulnerability-hunting toolkit built on idalib-rs 🦀 named with more classical flair than strictly necessary 
https://github.com/0xdea/rhabdomancer - finds calls to sketchy API functions in a binary
https://github.com/0xdea/haruspex - rips pseudocode straight out of the @Hex-Rays decompiler
https://github.com/0xdea/augur - pulls strings and related pseudocode from a binary

So much for being a polyglot 🤷

🛠️ Tool
===================

Buzz is a self-hostable workspace where humans and AI agents collaborate in the same channels, built on top of a Nostr relay architecture. Every message, reaction, workflow step, review approval, and git event is a signed event in a single append-only log. The identity model is uniform: agents and humans use the same keypair-based identity, the same audit trail, and the same channel membership semantics.

🔹 Key Features
• Agents as members, not bots. You add an agent to a channel the same way you add a person. The agent gets its own keypair, its own memberships, and its own audit history.
• Identity-based scoping. Agents are scoped by identity, not by permission flags. The README draws an analogy to how you would scope a human teammate.
• Full surface area for agents. Agents can open repos, send patches, review code, run workflows, edit canvases, orchestrate other agents, join voice huddles, and create channels.
• Unified search. Conversations, patches, workflow runs, and approvals are all the same event type, so they are searchable in one place.
• Feature branch as a room. A channel becomes the record of why code exists, with patches, CI results, review, and the merge decision co-located.

🔹 Technical Implementation

The backend is a Nostr relay. A Buzz community is selected by URL in the single-relay setup that ships today. Hosted operators can serve multiple communities behind multiple domains or subdomains, but all tenant-observable state is community-local. The project is written in Rust (the README jokes about a suspicious number of crates) and licensed under Apache 2.0.

🔹 Use Cases
• Asking an agent a project question and getting answers with linked thread references instead of vague summaries.
• Letting an agent triage a bug with scoped identity rather than blanket permissions.
• Running a release coordination channel where humans and agents coordinate on the plan.

🔹 Limitations

The source does not provide performance benchmarks, deployment requirements, or security threat models. The single-relay architecture may present scaling constraints for larger organizations. No independent verification of the agent capability claims.

City Explorer benchmark, round 2.

Fixed a fairness bug: axum's reqwest pools connections by default, letloop was opening a fresh TCP connection per upstream call instead. Added connection reuse to letloop, re-ran both.

Mean req/sec, 9 concurrency levels, wrk, one core each:

axum ██████████████████████ 9,419
letloop ██████████████████ 7,825

axum now leads throughput and tail latency at c=256. letloop still ~9x lower p99 at baseline (c=1).

Immich deployment is an exercise in a needless dependency tree walking.

By itself, Immich is a Node.js application, you might just run it with a node, using some knowledge bits from the official dockerfiles and scripts.

On the other hand, it is intended to be controlled by the `mise` tool (runtime polyglot manager), so I making some detours.

`mise` isn't in pkgsrc, so you'd need to build it in on illumos from sources on your own.

It is a Rust app, where its requirements `rattler`/`rattler_pty` (of Python/Conda) and `libdbus-rs`/`dbus-native-channel` fail to be built on illumos.

The fix for the first one was just submitted to the upstream, the second would require me to work in its requirement -`libc` crate.

I guess it's not going to go deeper than that (but it is three layers removed from the root already).

🛠️ Tool
===================

dnsglobe is a Rust-based terminal UI for checking DNS propagation across 34 public resolvers worldwide. It queries each resolver directly (no cache, EDNS0, TCP fallback for truncated responses) and presents results on an adaptive world map or rotating 3D globe, depending on terminal width.

🔹 Key Features

The tool supports a watch mode that re-polls until a record has propagated across all resolvers. Answers sharing any record are grouped together, so round-robin DNS configurations (where each resolver caches a different subset of an IP pool) count as one consistent answer rather than conflicting results. Outliers are flagged as ≠ DIFFERS once all results arrive.

EDNS Client Subnet support (RFC 7871) is built in via the --ecs flag, allowing you to query GeoDNS zones as a specific client network would. Multiple subnets can be specified, producing one table per subnet plus a convergence summary.

Anycast detection is a notable feature. For networks like Quad9, Cloudflare, Google, OpenDNS, CleanBrowsing, and Neustar UltraDNS, dnsglobe asks which site is actually answering. It uses TXT id.server.on.quad9.net for Quad9, CH TXT id.server for Cloudflare, egress subnet via TXT o-o.myaddr.l.google.com for Google, and TXT debug.opendns.com for OpenDNS. The discovered site appears in the Loc column as IATA-style codes (e.g., →YUL), and the resolver's map dot moves to the POP serving your queries.

🔹 Technical Implementation

The visual rendering adapts to terminal width: terminals with 157+ columns get a flat world map, narrower ones (131+) get a spinning 3D globe. Resizing across the threshold morphs one into the other. Ctrl+O toggles manually, and --view auto|map|globe forces a style.

Installation is available via Homebrew, cargo, AUR (source and prebuilt), and Nix flakes.

🔹 Use Cases

Verifying DNS changes have propagated globally, validating GeoDNS behavior from specific client subnets, and detecting resolver inconsistencies across regions.

🔹 Limitations

Limited to 34 predefined public resolvers. No custom resolver list mentioned in the source. The tool is focused on propagation visibility rather than performance benchmarking.

Toy Ghouls’ new toy: the GenieLocker ransomware

GenieLocker is a new ransomware family active since March 2026, targeting organizations in the Russian Federation, primarily in manufacturing. Attributed to the financially motivated Toy Ghouls group (also known as Bearlyfy, Labubu, and Laboo.boo), this custom-designed ransomware marks a shift from their previous reliance on third-party encryption tools like RedAlert, LockBit, and Babuk. GenieLocker exists in two variants: PE builds for Windows and ELF builds for Linux and ESXi. The Windows version features sophisticated capabilities including process termination, service shutdown, anti-debugging techniques, and advanced encryption using the libsodium library with XChaCha20-Poly1305 algorithm. Initial access typically occurs through compromised VPN credentials from trusted partners, followed by deployment of tools like Mimikatz, SoftPerfect Network Scanner, and SSH utilities for lateral movement before deploying ransomware using PsExec and PAExec.

XMRig Covert Ops: The Cryptomining Campaign That Abuses Trusted Access and Deploys Forensic Smokescreens

In May 2026, a sophisticated Monero cryptomining campaign was identified targeting Linux environments. Attackers gained initial access through trusted third-party relationships, then escalated to root privileges. Rather than operating openly as root, they weaponized Linux Pluggable Authentication Modules (PAM) to impersonate multiple low-privileged users, creating a forensic smokescreen and establishing redundant persistence through cronjobs. The operators suppressed system logging and deployed a customized XMRig 6.25.0 implant that self-unlinks after execution, running entirely in memory. The binary uses XOR encryption for configuration obfuscation and employs process masquerading to blend with legitimate processes. Campaign tracking revealed operations linked to the V25 Generation 26 family, connecting to the domain unable.download for mining pool communication.
