⚡ Weekly Recap: Vercel Hack, Push Fraud, QEMU Abused, New Android RATs Emerge & More

Monday’s recap shows the same pattern in different places. A third-party tool becomes a way in, then leads to internal access. A trusted download path is briefly swapped to deliver malware. Browser extensions act normally while pulling data and running code. Even update channels are used to push payloads. It’s not breaking systems—it’s bending trust.…

iPhone forensics expose Signal messages after app removal in U.S. case

An FBI case in Texas shows Signal messages can still be recovered from iPhones even after app uninstall, via system artifacts, challenging privacy assumptions. The recent revelations about FBI forensic access to Signal messages on an iPhone have reignited a long-standing misunderstanding about mobile privacy: the belief that disappearing messages and encrypted apps guarantee that…

Axios npm Attack Deploys Cross-Platform RAT

A brief compromise of the popular Axios npm package shows how quickly a trusted dependency can become a widespread threat.  Attackers hijacked a maintainer account and published malicious versions that silently installed a remote access trojan (RAT) during routine package installs, putting developer environments and CI/CD pipelines at risk. “While traditional risks like manual dependency…

Inside the ChatGPT DNS Exfiltration Flaw The issue…

Faster attacks and ‘recovery denial’ ransomware reshape threat landscape

Mandiant’s M-Trends 2026 report, released today at the RSA Conference, shows that attackers are moving faster, operating more collaboratively, and increasingly focusing on the systems organizations rely on to recover from breaches. The report, based on more than 500,000 hours of incident response engagements in 2025, finds that attackers are compressing key phases of the…

The ransomware economy is shifting toward straight-up data extortion

Ransomware remains a scourge that shows some signs of relenting, but incident responders and threat hunters are busier than ever as more financially-motivated attackers lean exclusively on data theft for extortion. Attacks that only involve data theft for extortion may not be more prevalent than traditional ransomware when attackers encrypt systems, but momentum is moving…

Perplexity Comet Browser Bug Leaks Local Files via AI Prompt Injection

A newly disclosed attack against Perplexity’s AI-powered Comet browser shows how agentic browsers can be manipulated into leaking sensitive data directly from a user’s machine.  Zenity Labs researchers demonstrated a zero-click attack that tricks the browser’s AI agent into reading local files and sending their contents to an attacker-controlled server. The attack “… results in…

Weekly Recap: Outlook Add-Ins Hijack, 0-Day Patches, Wormable Botnet & AI Malware

This week’s recap shows how small gaps are turning into big entry points. Not always through new exploits, often through tools, add-ons, cloud setups, or workflows that people already trust and rarely question. Another signal: attackers are mixing old and new methods. Legacy botnet tactics, modern cloud abuse, AI assistance, and supply-chain exposure are being…

ThreatsDay Bulletin: AI Prompt RCE, Claude 0-Click, RenEngine Loader, Auto 0-Days & 25+ Stories

Threat activity this week shows one consistent signal — attackers are leaning harder on what already works. Instead of flashy new exploits, many operations are built around quiet misuse of trusted tools, familiar workflows, and overlooked exposures that sit in plain sight. Another shift is how access is gained versus how it’s used. Initial entry…

Picus Red Report 2026 Shows Attackers Favor Stealth Over Disruption

Cyber attackers are quietly changing how they operate — and the latest Picus Red Report shows that disruption is no longer the goal.  Rather than encrypting systems or triggering immediate disruption, Picus Security found that adversaries are prioritizing stealth, persistence, and long-term access within enterprise environments.  “The 2026 Red Report confirms that the era of…
