Silent Swap clipper exploits browser extensions

🛡️ McAfee Labs uncovered an active campaign, dubbed Silent Swap, that deploys malicious Chromium extensions masquerading as a 'Google Notes' utility to intercept and replace cryptocurrency wallet addresses copied to the clipboard. The installers, observed in .NET and Golang variants, inject the extension into Chromium-based browsers by modifying protected preferences and recalculating security hashes to bypass store installation. The threat uses an EtherHiding technique to resolve C2 domains via the blockchain and performs dynamic, server-side wallet mappings to redirect funds to attacker-controlled addresses. Telemetry shows global infections, with higher concentration in India.

Critical SimpleHelp RMM authentication bypass exploited

đź”’ A critical authentication bypass in SimpleHelp's RMM software was exploited to forge a technician login token and deliver two previously unseen malware families. Researchers at Blackpoint Cyber found the flaw (CVE-2026-48558) allowed unauthenticated token forgery by skipping cryptographic signature checks in OpenID Connect. Attackers abused built-in file transfer and remote execution to deploy a Node.js loader named TaskWeaver and a cross-platform stealer called Djinn Stealer. The vulnerability received a CVSS score of 10 and was patched in late May; CISA added it to KEV on June 29.

GuardFall bypasses safety in open-source AI agents

đź”’ New research from Adversa AI, dubbed GuardFall, shows a decades-old shell trick can bypass simple blocklist checks in open-source AI coding agents, letting hidden destructive commands run. The flaw arises because filters inspect the command as plain text while shells like bash rewrite and expand that text before execution. Ten of eleven tested agents were vulnerable; only Continue defended by parsing commands the same way the shell does.

Lessons from underground: combating BEC threats

📣 Flare researchers examined underground forum discussions and tools used to orchestrate Business Email Compromise (BEC) campaigns, finding that attacks extend beyond email to include remote access, cash-out networks, and call centers. Actors target finance and leadership SaaS accounts, increasingly using AI to craft realistic messages and scale operations. Defenders should monitor exposed credentials, enforce MFA, train high-risk staff, and treat multi-channel contacts cautiously.

Study: 282 iOS Apps Expose LLM API Keys in Traffic

🔍 Researchers tested 444 iPhone AI chatbot apps and found 282 leaking paid AI access via network traffic, often as plaintext keys, reusable tokens, or unsecured backend relays. The team used a tool called LLMKeyLens to capture credentials without jailbreaking. Only 28% of affected apps were fixed after three months; many tokens remained valid and susceptible to costly misuse.

AI Transforms Capabilities of Video Surveillance

🛰️ The Financial Times reports on how AI is transforming video surveillance, drawing on examples from Israel, Iran and Russia. These AI tools let analysts ask natural-language questions of video streams rather than rely on limited preset searches. Analysts can now search for behaviors—such as two people exchanging a bag, repeated vehicle movements, or changes in appearance—creating new investigative possibilities. Officials call this shift a major advancement in surveillance capability.

ClickFix Emerges as Dominant Malware Delivery Method

đź”’ Analysis by ReliaQuest shows the ClickFix social engineering technique dominated malware delivery from March to May 2026. ClickFix tricks users into pasting attacker-supplied commands into trusted dialogs like Run, Terminal, or Script Editor, allowing payloads such as infostealers to execute while evading many defenses. The method has been used to deliver Windows malware and, notably, to deploy AMOS/Atomic Stealer to macOS via Script Editor. ReliaQuest urges equal monitoring for macOS and recommends user training and administrative restrictions to mitigate ClickFix risks.
