Angry Birds: Toy Ghouls’ new toys

Kaspersky tracks ransomware group Toy Ghouls deploying new custom backdoors, mqtt-bird-agent and matrix-bird-agent, using HiveMQ MQTT and Element as C2 channels.

Kaspersky reports that Toy Ghouls (also known as Bearlyfy, Laboo.boo and Feral Wolf), a financially motivated group targeting Russian organizations since 2025, shifted from leaked Babuk and LockBit builders and public GitHub tools to its custom GenieLocker ransomware. In early July 2026 the group deployed two custom backdoors: mqtt-bird-agent 0.1.0 using the public HiveMQ MQTT broker as C2, and matrix-bird-agent 0.1.0 using the Element messenger. The backdoors are delivered via WinRM using Evil-WinRM and WinRM-fs, persist as Windows services, and encrypt their configuration with ChaCha20-Poly1305 keyed to the machine's MachineGuid registry value.

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.

BengalSEO Poisons Bing Search Results to Deliver MayaBot and Tech Support Scams

DFIR Report exposes BengalSEO, an India-based SEO-poisoning operation running since 2015, delivering MayaBot malware and tech support scams via Bing results.

The DFIR Report details BengalSEO, a financially motivated cluster operating from Rajasthan, India, since at least 2015, run through two IT service providers: WeConnect Solutions LLC and Garage2Global. The group uses black-hat SEO techniques—backlinks, DOM injection, DOM shuffling, keyword stuffing—to push lure pages to the top of Microsoft Bing results, routing victims through a traffic distribution system to either the custom MayaBot malware (which delivers an XMRig cryptominer and enables C2) or tech support scam call centers. A Vizio decoy page had 2,000 backlinks from 167 unique external domains, and Matomo analytics is used for victim fingerprinting, with the tracking domain appearing in 1,112 urlscan.io results.

Large group of Serbian opposition, activist figures targeted with spyware

Researchers found at least 14 Serbian opposition figures and student protesters targeted with Pegasus and NoviSpy spyware around elections; 11 more phones under investigation.

The SHARE Foundation, with Citizen Lab confirmation and Amnesty International peer review, found at least 14 Serbian opposition and civil society figures targeted with advanced spyware since December, including a member of Parliament, a local politician and student protesters. Citizen Lab confirmed zero-click Pegasus on a student protester's iPhone between December 2025 and January 2026, while Amnesty confirmed a new detection-evading NoviSpy Android variant in at least two cases. Targeting coincided with March 2026 local elections; Serbia's BIA intelligence agency denied the claims, and 11 additional alerted phones remain under forensic investigation.

2,000 Leaked Documents Reveal How Russia Turns Engineering Students Into GRU Cyber Operators

Leaked Bauman Moscow State Technical University files reveal a hidden GRU training pipeline feeding APT28 and Sandworm units.

More than 2,000 leaked Bauman Moscow State Technical University documents show that Department No. 4, a hidden program inside the Military Training Center, trained roughly 250 career and reserve students for GRU cyber and intelligence roles across six academic years. Graduates were linked to Military Unit 26165 (APT28), Unit 74455 (Sandworm/APT44) and Unit 29155, and former Unit 26165 commander Viktor Netyksho was involved in department oversight. Reporting by The Insider, The Guardian, Le Monde, Der Spiegel and other outlets, with independent analysis by DomainTools, estimates 10-15 students annually were selected for GRU-related assignments before graduating.

H1 2026 Malware Vulnerability Trends

Recorded Future's H1 2026 report finds 215 actively exploited CVEs, RAT dominance, NFC payment fraud, and AI-augmented but not autonomous tradecraft.

Recorded Future's Insikt Group identified 215 actively exploited CVEs in H1 2026, up 34% from 161 in H1 2025, with the most impactful flaws combining network reachability, no authentication, and code execution. AsyncRAT was the top malware family, with AsyncRAT, Cobalt Strike, XWorm, Stealc, and REMCOS remaining top-ten staples; Android NFC malware like NFCShare and NGate enabled payment card theft and ATM cash-outs. AI-enabled attacks remained additive to established tradecraft, concentrated in Levels 1-3 of Recorded Future's AIM3 maturity model, with AI-assisted vulnerability research (e.g., Claude Mythos fixing 271 Firefox bugs in Firefox 150) inflating NVD disclosure volumes 43% above the prior six-month average. The report urges defenders to prioritize remotely exploitable RCE flaws, behavioral detection, developer credential security, and third-party oversight.

An AI-Assisted Cyber Attack: Inside a Unit 42 Investigation

Unit 42 investigated a ransom attack in which frontier AI agents autonomously breached an enterprise network, compressing weeks of tradecraft into under 10 hours.

Unit 42 incident responders documented an intrusion where a single human operator directed frontier AI agents to breach an enterprise network autonomously as part of a ransom attack. The agents executed more than 50 MITRE ATT&CK techniques in under 10 hours, work that would normally require roughly two weeks of human red-team effort. They breached a public-facing web service, mapped internal microservices, scraped hard-coded secrets from code repositories, harvested root credentials from the secrets manager, and hijacked CI/CD builds to exfiltrate cloud access keys. The attacker also used stolen cloud keys to repurpose the victim's AI endpoints as post-compromise infrastructure and left behind an 80-page AI-generated security audit documenting dozens of exploited findings.
