Don’t Call Us, We’ll Call Your APIs | TraderTraitor Backdoors Resurface on Victim With No Crypto Ties

Executive Summary Following disclosure of the TraderTraitor attack against LayerZero in April 2026, SentinelOne identified an additional victim with the same macOS backdoors. Our analysis explores the mechanics of these backdoors and the expanded targeting against a victim in the IT services sector with no relationship to cryptocurrency trading. We also identified more weaponized GitHub repositories from the social engineering schemes used to target job seekers in these campaigns. This report…

HEAVYGRAM: A Telegram-based Surveillance Backdoor Linked to Handala Hack

Group-IB Threat Intelligence analyzes HEAVYGRAM, a Telegram-based Windows backdoor attributed with moderate confidence to the Iran-linked threat actor Handala Hack. Active since Fall 2023, it has been used to surveil Iranian dissidents, journalists and government opponents, enabling remote command execution, data exfiltration, and persistence over Telegram command-and-control.

SPOJENO PŘES CVE We've got one word for it, and it's usually the wrong one

Welcome to this week’s edition of the Threat Source newsletter. Ask anybody in this industry what the work does to the health of the people who do it and you get one word back: burnout. It's a fine word, in and of itself. It’s easy to reach for, understandable to everyone… and it's the wrong one, most of the time. So, story time. Last year I gave an interview with the amazing Hazel Burton about VPNFilter, and my run-in with burnout. I was a manager during that time, and it took a toll on me and…

BlueMoon exploit kit turns Chrome and Windows flaws into attacks

BlueMoon, a shared Chrome and Windows exploit kit, shows why “patch later” is becoming a dangerous gamble. Security updates are easy to put off. The browser still opens, Windows still works, and choosing to relaunch your browser or restart your computer later can feel harmless. But a newly documented exploit kit called “BlueMoon” shows how quickly patching delays can become dangerous. Proofpoint Researchers found four espionage groups using the same exploit chain against Chrome browsers running…

DPRK APTs: Ted backdoor and curlRAT target South Korean media and automotive sectors

OverviewA new Linux toolkit, identified by Rapid7 Labs, has been targeting organizations across South Korea’s automotive and media industries with minimal detection. The campaign made use of a HAProxy instance named “ted backdoor”, alongside trojanized versions of crond, agetty, atd, sshd, and polkitd. This previously undocumented framework enabled threat actors to execute remote commands on compromised servers, inject malicious scripts into web traffic, perform credential harvesting, and…

Mirage Kitten targeting aviation and FinTech sectors across the Middle East and Africa with a new malware set

While monitoring Mirage Kitten activity, we uncovered a previously undocumented malware family that we dubbed NodeRabbit. We identified the first sample on a system in Afghanistan. Further threat hunting revealed two additional, more advanced, variants: one on a system in Egypt and another on a system in Ethiopia. NodeRabbit is a cross-platform remote access trojan (RAT) built with Node.js. It targets Windows, Linux, and macOS. Its operators deliver it through spear-phishing messages on…

ValleyRAT masquerading as adware

Attackers typically try to pass off malware as legitimate applications or as potentially unwanted programs that users deliberately search for and download, such as cheats or cracks. They often rely on ad and affiliate networks to deliver their creations to victims’ devices. This post examines a less conventional case: a well-known backdoor distributed under the guise of adware. The attackers may have chosen this distribution method because the adware was signed by the developer. On top of that,…

You can’t patch everything. So what do you fix first? Findings in Q2 2026 have changed traditional answers.The latest Quarterly Threat Landscape Report from Rapid7 Labs shows vulnerability disclosures still surging while attackers use automation and AI-assisted tooling to compress the time between disclosure and exploitation.

Iran War Cyber Threat Landscape | A Midyear Assessment on What Matters

In April, SentinelLABS’ Tom Hegel published an initial assessment of the first five weeks of the conflict. Three months later, the evidence supports refinement. Executive Summary The cyber risk remains quieter than the public narrative. It rests on persistent access, trusted administration, service-provider pathways, selective disruption, and personas that magnify technical effects. Iran-linked activity is not a single threat set. MOIS, the IRGC Intelligence Organization, the IRGC Cyber…

AI Security Report 2026

For years, the cyber security industry tracked AI as a force multiplier: something that made existing attack techniques faster, cheaper, and more accessible. That framing was accurate. But the Annual AI Security Report 2026 from Check Point Research documents a transition that goes further. AI has crossed from assistant to operator. Where it once helped attackers prepare, it now runs the operation. Key observed findings AI has crossed from development aid to live attack operator. It now does…
