Three Threat Groups Target Russian Enterprises With Backdoors, Ransomware, and Wipers

Kaspersky details NightEagle, Hacking Cat, and Toy Ghouls targeting Russian enterprises with Exchange backdoors, Gorilla RAT, and destructive Monkey ransomware.

Kaspersky reports three threat clusters targeting Russian enterprises: NightEagle (APT-Q-95), the pro-Ukrainian hacktivist group Hacking Cat, and Toy Ghouls. NightEagle uses compromised VPN credentials and the GhostContainer modular backdoor to fully compromise Microsoft Exchange servers, chaining CVE-2020-0688 exploitation, BlueKeep (CVE-2019-0708), Active Directory vulnerabilities, and DCSync to seize domain controllers. Hacking Cat exploits Exchange flaws including CVE-2021-26855 and CVE-2026-42897 to deliver the Gorilla RAT and multiple Monkey ransomware variants written in Rust, .NET, C++, and Golang targeting Windows, Linux, and VMware ESXi, with some variants acting as wipers that never store the encryption key.

A heap overflow and SSO misconfiguration to compromise OpenAI internal repos

Hacktron researchers chained a libheif heap overflow in Discourse with an OpenAI SSO flaw to take over employee ChatGPT/Codex accounts and access internal repositories.

On July 25, 2026, Hacktron researchers chained a heap buffer overflow in libheif 1.19.7/1.19.8 (missing Debian security backports, upstream fix never assigned a CVE), reached through Discourse image uploads processed by ImageMagick, to gain remote code execution on community.openai.com. Combined with an SSO identity misconfiguration in the 'Sign in with OpenAI' flow, they took over employees' ChatGPT/Codex accounts with connected GitHub, Slack, and email access, and proved it by opening PR #1186742 in OpenAI's internal openai/openai monorepo. They reported the issues for coordinated patching, received a $6,500 bounty from OpenAI, and Debian shipped fixed libheif packages on August 8, 2026. The team used Claude Opus 4.8 and Claude Opus 5 to locate the missing backport and autonomously develop working x86-64/ARM64 exploits.

America's Driver's License Breach Is a National Security Disaster

Dark web service Nexus sells 153 million US/Canadian driver's licenses linked to a breach of identity verifier IDScan.

Krebs on Security revealed a dark web service, Nexus, selling access to 153 million driver's licenses and 3 million travel documents from US and Canadian citizens, roughly 63 percent of all US licenses. Circumstantial evidence links the data to identity verification firm IDScan, which confirmed it is investigating a breach, and the FBI is probing the incident. Licenses belonging to senior US officials, including Pete Hegseth, an FBI assistant director, and Krebs's own contacts were verified as genuine. The exfiltration appears ongoing, with the database growing by nearly 400,000 licenses in a single day, and the data carries significant national security value for foreign intelligence services.

Strong fundamentals make next-gen security possible

A former CISO for Hyatt and United Airlines argues foundational controls—asset inventory, identity, resilience—outperform repeatedly buying new security tools.

The author, a former security leader at Hyatt and United Airlines, argues that mastering foundational controls delivers more impact than cycling through expensive new tools. The piece highlights asset discovery with a single source of truth, identity hardening via MFA and passkeys, and risk-based prioritization using frameworks like CIS CSC. It also stresses resilience and recovery planning, including secure backups and regularly practiced incident processes.

“Zero-Code Cloaking”: Attackers Weaponize Google Search and Hacked .ac.th Domain to Bypass Ad Moderation

Attackers chain Google search results, a hacked Thai .ac.th domain, and redirects to push illegal casino ads past moderation, at industrialized scale across gov/edu sites.

ADEX researchers documented a 'zero-code cloaking' technique in which an ad's destination URL loads a Google search results page whose poisoned top result is a casino page planted on the compromised Thai university domain km.chpc.ac.th, which then redirects users to illegal gambling sites. Because every visitor receives identical content, ad-verification tools that inspect only the declared landing URL detect nothing malicious. ADEX cites data showing roughly 30 million gambling URLs across about 1,000 Thai public-sector sites, hundreds of blocked gov/edu domains in Indonesia, and underground markets selling access to more than 15,000 compromised .gov and .edu domains. Google's site reputation abuse policy offers little coverage because hacked site owners are victims rather than willing participants.

CISA Releases Guidance on Deploying Cyber Decoys

CISA issued guidance on deploying honeypots, honeytokens, and decoy systems to detect adversaries and gather threat intelligence in critical infrastructure.

CISA released guidance on deploying cyber decoys, including lures, tripwires, decoy artifacts, honeytokens, and honeypots, within critical infrastructure organizations to complement Zero Trust models. The guidance outlines a three-phase operational process of preparation, execution, and understanding, advising decoys be placed where users rarely interact and configured to produce high-fidelity alerts. It aims to help defenders detect adversaries who use legitimate credentials, native tools, and living-off-the-land techniques, while enabling cost-effective threat intelligence collection.

Critical ScreenConnect flaw now actively exploited in attacks

CISA confirms active exploitation of critical ConnectWise ScreenConnect flaw CVE-2026-84869, ordering federal agencies to mitigate within three days.

ConnectWise's ScreenConnect flaw CVE-2026-84869, an improper privilege management and missing authorization bug, lets attackers with basic privileges transfer or execute files through active remote sessions in low-complexity attacks without user interaction. It is patched in ScreenConnect 26.6.5; CISA added it to the KEV catalog and ordered US federal agencies to secure systems within three days. Shadowserver tracks over 1,000 unpatched exposed instances, mostly in North America (758) and Europe (180). This is the fourth actively exploited ScreenConnect flaw since 2024; earlier issues were abused by Kimsuky and ransomware gangs.

SilkParasite Infrastructure Links SpiceRAT to Central Asian Targets

Hunt.io linked SpiceRAT, NodeEdgeRAT, and NomadRAT C2 servers to the SilkParasite campaign targeting Central Asian governments since mid-2022.

Hunt.io and researcher Guy Yasur mapped C2 infrastructure tying three of seven RAT families from Bitdefender's SilkParasite report through shared TLS certificates, parent domains, and a cloned RTX Corporation homepage. One certificate spoofing Uzbekistan's state railway was issued by TLC, a CA funded by China's CAICT, and domains impersonate state entities in Turkmenistan, Uzbekistan, Tajikistan, and Kyrgyzstan. Passive DNS pushes the campaign back to mid-2022, and the infrastructure overlaps China-nexus activity including FamousSparrow and IndigoZebra.

Phishing Research Challenges Conventional Security Awareness Testing

Pistachio's 2.47 million phishing simulations across 1,200 organizations show click rates alone mislead, with 30% of IT staff clicking and leak rates more predictive.

Between June 2025 and May 2026, Pistachio sent 2.47 million simulated phishing attempts to more than 123,000 employees at over 1,200 organizations, analyzing click, credential-leak and reporting behavior. Click rates ranged from 26% in Design to 41% in Construction; 30% of tech development and IT staff clicked at least once, while financial services were the most resilient sector. The report argues that click rate alone creates a false sense of security and that combined click, leak and report trends are better resilience indicators.

Security through obscurity is dead, and AI delivered the fatal blow

AI agents are killing security through obscurity, accelerating vulnerability discovery and patch-gap exploitation, experts warn, with OT/ICS systems most at risk.

An opinion/analysis piece arguing AI has made security through obscurity obsolete, citing record vulnerability disclosure volumes after Microsoft's Patch Tuesday addressed 974 CVEs. FBI Cyber Division assistant director Brett Leatherman said latest AI models found significant vulnerabilities in open source libraries running on most web servers. The article cites at least four espionage crews (most suspected China-linked) exploiting Chromium's patch-gap window with a rapid exploit kit, and a five-agency advisory on AI-generated exploitation scripts breaching internet-exposed Siemens S7 Series PLCs at water, manufacturing, and energy facilities. Experts including John Hultquist, Chris Inglis, and Katie Moussouris warn AI erodes the expertise barrier protecting obscure OT/ICS systems while defensive AI patching lags, with studies showing AI-generated patches fail more than half the time.

Flock cameras are riddled with security vulnerabilities and hardcoded creds

Leaked Flock ALPR camera firmware reveals EOL Android 8.1, a 2017 Linux kernel, and hardcoded API keys granting access to production credentials.

DDoSecrets published filesystem images from an in-use Flock ALPR camera, obtained by the hacker collective stegan0gram and investigated by 404 Media and Wired. Micah Lee's analysis shows the camera runs Android 8.1 with a security patch level of 2018-06-05 and Linux kernel 3.18.71, missing roughly eight years of Android fixes. The firmware exposes a hardcoded API key for Flock's hpnotiq backend that can retrieve Auth0 client credentials for any camera by MAC address, with credentials stored in plaintext. Likely unpatched flaws include CVE-2021-1905 (Qualcomm Adreno use-after-free) and CVE-2018-9568 (WrongZone kernel socket type confusion); Flock says it received no reports via its disclosure policy.

Should you care about an “AI slowdown?”

Cisco Talos argues an AI slowdown would barely affect cybersecurity, urging focus on fundamentals and Qilin ransomware trends in Japan.

Cisco Talos' newsletter opines that an AI development slowdown would have limited security impact since current models already uncover substantial vulnerabilities. It highlights Talos findings that Japan's ransomware incidents rose nearly 5 percent in H1 2026, driven by The Gentlemen RaaS group and Qilin, which uses LLMs to generate destructive scripts and targets SMBs with double extortion. The newsletter also recaps headlines including an Android app-cloning campaign, Apple's 200-patch release, ClickFix lures, and VectraRAT.

Chosen Brick, Iran’s Surveillance Malware

UK, US, and Dutch agencies warn Iranian CHOSEN BRICK malware targets dissidents and journalists via Telegram, harvesting contacts, emails, and messages since 2025.

The UK NCSC, FBI, and Dutch AIVD jointly attributed the CHOSEN BRICK Windows malware family to Iranian intelligence services, used since at least 2025 against dissidents, journalists, and activists worldwide, including in the UK, US, and Netherlands. Operators build rapport over WhatsApp or Telegram, impersonating known contacts or platform support, then deliver lures disguised as installers for Pictory, RunwayML, Norton Antivirus, Telegram, Adobe Flash Player, or KeePass, or fake MRI results. The malware persists via registry Run keys, adds Microsoft Defender exclusions, and uses per-victim Telegram bot IDs for C2, with newer versions adding HTTPS or SOCKS5 proxies. Some victims' data appeared on pro-Iranian leak sites, raising harassment and physical-safety risks.
