Microsoft: Python-based infostealers targeting macOS

⚠ Microsoft warns that information-stealing campaigns are expanding beyond Windows to target Apple macOS by leveraging cross-platform languages like Python and abusing trusted distribution platforms. Since late 2025, attackers have used malvertising and Google Ads to redirect users to fake sites that employ ClickFix lures and DMG installers to deploy families such as Atomic macOS Stealer (AMOS), MacSync, and DigitStealer. Campaigns use fileless execution, native macOS utilities, and AppleScript to harvest browser credentials, session cookies, iCloud Keychain items, and developer secrets. Organizations are urged to train users on malvertising and fake installers, monitor Terminal and iCloud Keychain access, and inspect network egress for POSTs to newly registered or suspicious domains.

AI-Driven AWS Attack: From Exposed Key to Admin in Minutes

⚠️ Sysdig researchers observed an AI-assisted intrusion in November 2025 that converted exposed AWS credentials in a public S3 bucket into full administrative control in under eight minutes. The attackers exploited an IAM user with Lambda and limited Amazon Bedrock access, injected malicious code into an existing Lambda function, and generated admin keys from the function output. They then moved laterally across multiple principals, invoked multiple foundation models (LLMjacking), disabled model-invocation logging, and attempted to provision costly GPU instances to run ML workloads. Sysdig recommends enforcing least privilege, restricting UpdateFunctionCode and PassRole, protecting S3 buckets, enabling Lambda versioning, and turning on Bedrock logging.

PDF Phishing Campaign Targets Corporate Dropbox Credentials

🔒Forcepoint X-Labs has warned of a multi-stage phishing campaign that uses short, business-themed emails and PDF attachments to harvest corporate Dropbox credentials. The PDFs contain embedded AcroForm links that limit scanning by security tools and redirect victims to a legitimate cloud-hosted portal serving a spoofed login page. By leveraging reputable cloud infrastructure, the attackers reduce suspicion and bypass many automated reputation checks. Submitted credentials are exfiltrated to a Telegram channel, enabling account takeover and follow-on abuse.

Moltbook Misconfiguration Exposes User Data and API

🔓 Security researchers at Wiz discovered a public Supabase API key in Moltbook’s client-side JavaScript that granted unauthenticated read/write access to the production database. The misconfiguration—absence of Row Level Security (RLS) policies—exposed around 1.5 million agent tokens, roughly 30,000 email addresses and thousands of private messages. With write privileges an attacker could impersonate any agent, inject malicious content or prompt-injection payloads, and deface the site. Moltbook’s developer has since remediated the issue after multiple rounds of fixes with Wiz.

Responding to Ransomware: Forensics, Triage, and Policy

🛡️ Stay calm and avoid rash moves when ransomware hits: shutting down systems can cause 'forensic suicide' by destroying volatile evidence such as RAM. Joanna Lang-Recht recommends isolating affected hosts from networks rather than powering them off, preserving forensic images, and engaging specialized incident response teams. Prioritize containment, secure offline backups, and clear crisis roles. Treat negotiation as an economic decision and rely on trained negotiators rather than emotional engagement.
