Group-IB detailed ClickLock, a macOS infostealer that coerces victims into handing over their login password. It arrives when a user is tricked into pasting a command into Terminal from a fake verification page, then shows a fake system dialog asking for the password. If the victim refuses, ClickLock begins killing core apps like Finder, the Dock, and browsers every 210 milliseconds, leaving only a password box on an unusable desktop, while also suppressing security notifications. Once the password is entered, it steals the Keychain, browser credentials, and cryptocurrency wallets and sends them to a Telegram bot. Group-IB counted at least 100 targets across 33 countries, over half in Europe.
Researchers described Agent Data Injection, a new twist on prompt-injection attacks against AI agents. Rather than smuggling in fake instructions, it exploits the weak separation between trusted and untrusted data so that attacker-supplied content is mistaken for the agent's own trusted data, using deliberately ambiguous delimiters the model misreads. In tests against web and coding agents, this let an attacker steer an agent's clicks or actions, succeeding up to half the time even against defenses that block ordinary instruction injection. Some approaches helped: tagging page elements with random, unguessable identifiers roughly halved success, while strict tracking of where data came from stopped it but sharply reduced how many tasks agents completed.
Cisco Talos detailed a financially motivated Russian group, tracked as UAT-11795, that spreads a new backdoor called Starland RAT through trojanized installers for legitimate software including WebEx, Zoom, MobaXterm, DBeaver, and FaceIT. Active since at least mid-2025 and mainly hitting US victims, the campaign likely uses fake verification lures to deliver the installers. Once run, the malware sets up persistence, tries to escalate privileges, and detects sandboxes, then steals browser data and more than 40 kinds of cryptocurrency wallets, profiles the machine, and maps Active Directory. It can take screenshots, run shell commands, inject shellcode, and pull down further payloads, giving the operator broad control.
Trend Micro documented a Russian-speaking attacker who used Google's open-source Gemini CLI as a hands-on hacking assistant to build and run a small botnet. Across more than 200 sessions, a jailbroken Gemini took the role of an "authorized pen tester," saved stolen credentials, and even suggested improvements dozens of times. Working from a roughly 5KB set of plain-text files holding a jailbreak prompt and a command-and-control playbook, the AI handled the operation through natural-language requests: at one point it migrated the entire command server to a new host with a Cloudflare tunnel in about six minutes and debugged its own errors. The malware itself was crude; the AI was the force multiplier.
Attackers backdoored several widely used @asyncapi npm packages, together drawing around three million weekly downloads, by hijacking the project's GitHub Actions build pipeline rather than stealing a maintainer's npm token. Because the project's own release workflow published the malicious versions, they carried valid provenance signatures, which prove where a package came from but not that the code was trustworthy. The payload was hidden in normal runtime files behind trailing whitespace and ran when the module was imported, not on install, so defenses aimed at install scripts missed it. Once loaded, it fetched an encrypted second stage, stole credentials and cloud and registry tokens, and planted persistence, even in developer tool configuration files.
Kaspersky detailed OkoBot, a Windows malware framework active since 2025 whose standout module, SeedHunter, tricks hardware-wallet owners into giving up their recovery phrase. On an infected PC, the malware waits for wallet software like Ledger Live, Ledger Wallet, or Trezor Suite, sometimes until the device is plugged in, then displays a malicious page asking for the seed phrase from inside the wallet's own genuine app. Because the surrounding application is the real one the victim installed, the request looks legitimate, but anyone who types in the phrase hands over full control of their funds. Kaspersky counted hundreds of victims across more than 25 countries, and the framework remains active.
Researchers at JFrog found 148 npm packages that abused the registry not to attack developers but as free hosting for a booby-trapped web proxy aimed at students trying to bypass school filters. Anyone who opened one of the proxy sites had their browser quietly conscripted into a distributed denial-of-service botnet, flooding target servers with HTTP and WebSocket traffic, alongside injected ads and tracking. Crucially, the packages contained no install-time scripts and were never meant to be added to a project, so dependency scanners and install sandboxes, which watch what runs on install, would not catch them. The operators can re-arm the dormant attack code with a single commit.
Researchers at Blackpoint Cyber detailed LabubaRAT, a previously undocumented Rust-based remote access trojan that disguises itself as NVIDIA software to blend into target systems. It arrives as an executable impersonating NVIDIA's container runtime, then profiles the host, identifying installed browsers and security products such as Microsoft Defender, CrowdStrike, and SentinelOne. From there it can run commands and scripts, capture screenshots, move files, and proxy traffic, and it communicates over multiple channels, including HTTPS, WebView2, and DNS tunneling, so access survives if one path is blocked. Its command server details are supplied at runtime, letting attackers reuse the same binary across campaigns, and there are signs it is sold as a service.
LastPass is warning that attackers are impersonating it and Bitwarden with fake security alerts to lure password-manager users to phishing sites. The emails, sent from look-alike domains rather than the real services, mimic corporate notices about updated security policies and push recipients to a page impersonating DocuSign. LastPass stresses its systems were not breached and the messages did not come from its infrastructure. Password managers are attractive phishing targets because compromising one can unlock every stored credential, and users often trust vendor-branded alerts. Related campaigns have pushed fake more-secure desktop apps that actually install remote-access tools, and similar lures have impersonated other password managers.
Researchers demonstrated MemGhost, an attack that uses one email to plant a false, persistent memory in an AI personal assistant with inbox access. Because these assistants keep notes about the user and reload them every session, a crafted message can trick the agent into saving a fabricated fact while keeping its reply innocuous, so the tampering goes unnoticed and steers later answers. The team trained an attacker model to write such emails automatically, reporting high success against open-source and commercial agents and showing it transfers across memory backends and survives several defenses. Unlike earlier one-shot injection that leaked data only in the moment, MemGhost's memory persists long after the email is gone.
