🔍 Pivot From One JA4+ Fingerprint to Related Infrastructure

JA4+ fingerprints are built into Hunt and exposed as pivots across our platform.

In the example shown here, we begin a search with a JA4+ certificate fingerprint and quickly surface matching infrastructure at scale, including IPs, ports, hosting companies, HTTP status, and last-seen dates.

From there, analysts can open an IP and keep digging into ASN data, open ports, software, pivots, and history.

A single fingerprint is enough to open a much wider investigation path.

⚠️ China-Linked TA4922 Targets Europe and Africa With Atlas RAT

https://t.co/tpCgJJzFSf

The China-linked group TA4922 is moving beyond Asia and targeting organizations in Germany, Italy, the UK, and South Africa.

The group uses localized phishing lures around payroll, VAT, taxes, invoices, HR, and government compliance.

Atlas RAT is the main payload here, giving the operators access to steal files, log keystrokes, grab screenshots, record audio or webcam feeds, pull down extra payloads, and avoid basic analysis.

TA4922 is also using RomulusLoader, SilentRunLoader, and ValleyRAT.

💡How TTP Hunting Helps Teams Catch Threats Earlier

In this entry from our glossary, we break down TTP threat hunting and why it matters.

Attackers do not move randomly: they repeat patterns, test techniques, and leave behavior behind.

Instead of waiting for alerts, analysts look for the tactics, techniques, and procedures behind real attacks: lateral movement, credential dumping, LOTL activity, suspicious infrastructure, and more.

What matters is not only finding threats faster, but also understanding how attackers operate and turning their own playbook against them.

Based on prior public research by @SentinelOne (great job!) into PCPJack, we kept digging into their infrastructure and found an open directory on one of their known C2 servers. No authentication required. Twelve files exposed on port 8444, including source code, compiled binaries, and deployment state logs.

https://t.co/PyD8VPuQWc

What those files revealed was a Sliver-integrated toolkit converting compromised Linux servers into a persistent SMTP relay network.

- 12-file toolkit sitting exposed with no authentication
- 3 generations of deployer scripts, 50 beacons to 230 in a single wave
- SMTP quality gate pre-filtering hosts by mail relay capability
- Verified proxy list syncing every 5 minutes to a downstream server

🚩 Russia-Linked Gamaredon Unleashes GammaWorm Against Ukraine

https://t.co/b9aZXSkLSS

Gamaredon, a Russia-linked APT focused mainly on Ukraine, is now using a new malware strain called GammaWorm against Ukrainian networks.

The campaign starts with a malicious XHTML file and a WinRAR flaw, then drops the worm through the Windows Startup folder.

GammaWorm hides modules in NTFS Alternate Data Streams, spreads through USB sticks and network drives, and uses Telegram and Cloudflare as dead drops for live C2 addresses.

🕵️‍♂️ Infrastructure-Level Threat Hunting With Host Radar

Hunt's Host Radar helps analysts stop treating malicious infrastructure as a pile of disconnected indicators.

It maps activity by country, company, domain, and provider, then ties together C2s, phishing sites, malicious open directories, and IOCs.

In the CN view shown here, you can quickly compare providers like China Unicom, Alibaba Group, Tencent, China Telecom, and more, then drill into their activity.

This provider-level view makes threat hunting cleaner, faster, and harder to fool.

⚠️ SideCopy Deploys XenoRAT Malware in New Afghanistan Campaign

https://t.co/SSC3mvhs63

The Pakistan-linked threat group SideCopy is back with a new campaign, this time deploying XenoRAT malware against Afghanistan’s Ministry of Finance.

The operation targeted finance officials across all 34 Afghan Mustoufiats, using a spear phishing ZIP with a malicious shortcut disguised as a PDF.

The chain abused mshta.exe, loaded payloads from a compromised Afghan education domain, and deployed XenoRAT 1.8.7 with registry and scheduled task persistence.

⚙️ Turn IP Addresses Into Threat Hunting Leads Using Hunt's API

An IP can tell you more than just "where."

With Hunt’s IP Enrichment API, a single request can return observed activity across certificates, malware C2, JARM, HTTP data, protocols, SSH, honeypots, phishing, and open directories.

That means faster context for investigation workflows, without jumping between separate datasets.

The attached image shows an example of this enrichment through an API request, with the response trimmed to fit the visual, turning one IP into investigation-ready data.

🚩 Iran-Linked Black Shadow Targets IT and Recovery Systems

https://t.co/6Xi9fZS1F7

The Iran-linked threat group Black Shadow has launched a new campaign against Middle Eastern organizations, and it goes beyond data theft.

The operation combines exfiltration with deliberate destruction across IT and recovery systems: VMware vCenter, Windows volumes, SQL Server databases, application servers, and Veeam backup chains.

The goal is not just to break systems but to make recovery much harder.

🚨 Russia-Linked APT GREYVIBE Targets Ukraine With AI-Assisted Malware

https://t.co/MPwcLTe1oZ

GREYVIBE is a Russia-linked APT active since at least August 2025, targeting Ukraine and Ukrainian-related organizations.

The group has used five attack chains across spear-phishing emails, fake CAPTCHA pages, fraudulent Ukrainian adult-club sites, fake charity pages, and Android spyware lures.

AI seems to be built into several parts of the operation, from code and obfuscation to backend work and image generation.

The upside: the group has made several mistakes, from exposed backend functions and VirusTotal test uploads to slangy artifact names.

🚩 ShinyHunters Claims Charter Leak With 42M Records

https://t.co/nFGRT9GNGz

ShinyHunters is making headlines again, this time with a claimed Charter Communications leak.

The group published data it says was stolen in April, including over 42 million customer records. The breach could impact nearly 4.9 million people, with the dataset reportedly including names, addresses, phone numbers, and 85,000 employee-related records with job titles.

Charter says only sales tools for business customers were impacted, and that no CPNI or sensitive PI was released.

📌 Looking Back at the Iranian-Nexus Operation Against Oman's Government

A few weeks ago, we published a report on an Iranian-nexus operation targeting Oman’s government.

One exposed open directory revealed a working C2 environment, exploit scripts, webshells, session logs, and exfiltrated data tied to government systems.

The campaign hit 12 ministries and exposed over 26,000 citizen and Ministry of Justice records.

⚠️ HTTPSpy, HelloDoor, and VS Code Tunnels Enter Kimsuky’s Playbook

https://t.co/iQIEBRydpZ

Kimsuky, a North Korea-linked threat actor, is changing tactics.

Recent campaigns used fake South Korean security software pages, a fake Webex page built around a real meeting schedule, and payloads leading to HTTPSpy.

Their toolkit also keeps expanding: HelloDoor, HttpMalice, HttpTroy, AppleSeed, HappyDoor, VS Code tunnels, Cloudflare Quick Tunnels, and DWAgent. It’s a mix of custom malware and legitimate remote access tooling.

🚨 Government Data Becomes a Bigger Target Across Latin America

https://t.co/M2yBgJfuOP

Latin American cybercriminal groups are putting government data under heavy pressure.

This is not just one country or one incident. La Pampa Leaks claimed access to 5.8 million Uruguayan citizen records, Chronus Group claimed data from 25 Mexican government agencies and groups, and Colombia’s health ministry reportedly faced 23 million attempted attacks in March.

The playbook is not always classic ransomware. In many cases, attackers skip encryption and focus on siphoning databases, monetizing citizen records, or using leak claims to pressure victims in public.

Carnival has confirmed a breach affecting nearly 6 million people after attackers used social engineering to access part of its IT systems.

The stolen data reportedly included names, dates of birth, email addresses, genders, locations, and loyalty program details tied to Holland America’s Mariner Society.

ShinyHunters claimed the attack back in April.
