Your browser extension logo just became malware. Not the code. The actual image file. A PNG icon sitting in your toolbar, looking normal, hiding JavaScript that takes over your browser. Over 1 million victims through GhostPoster. Part of a larger operation hitting 8.8 million. Seven years undetected. 🧐

Last week, researchers revealed the full scope of a campaign they call GhostPoster. Koi Security published the first findings in December 2025. LayerX followed up with additional discoveries on January 15, 2026. And it is worse than anyone thought.

GootLoader is back. This week, researchers discovered their newest trick: a way to make security tools completely blind. Your antivirus scans the ZIP file. Nothing found. WinRAR tries to open it. Fails. 7-Zip tries. Also fails. Corrupted file, right? But when you double-click it, Windows opens it just fine. And now you’re infected. 🧐

The trick is simple but brilliant. They take 500 to 1000 ZIP files and glue them together into one massive file. Most analysis tools read ZIP files from the beginning. They hit the first archive, see garbage, and crash. But here is the thing about ZIP files. They are actually read from the END. The “End of Central Directory” record tells the reader where to find the actual content. Windows knows this. It skips all the junk, finds the last valid archive, and happily extracts the malware.

Netflix. Twitch. iCloud. The servers of the CIA and NSA. 30% of all cloud infrastructure worldwide runs on Amazon Web Services. Two missing characters in a regex filter nearly compromised all of it. 😬

A ^ at the start and a $ at the end. That’s what was missing from a security filter, and that’s all it would have taken for attackers to inject malicious code into the AWS JavaScript SDK.

Someone sends you an audio message. You don’t open it, you don’t play it, you don’t even look at your phone. And you’re already hacked. 😏 Google Project Zero just published a three-part series this week showing exactly how they built a working exploit chain for the Pixel 9. No clicks required and no interaction at all. Just receive a message and your phone is compromised.

CVE-2025-54957

The vulnerability sits in Dolby’s audio decoder, a component that ships on almost every Android phone sold today. Pixel, Samsung, and dozens of other brands all use it. When someone sends you an audio message through SMS or RCS (the default messaging on most Android phones), your phone automatically decodes it for transcription. Before you even see the notification, the malicious code is already running.

January 13, 2026. Microsoft patches a vulnerability in Copilot that let attackers steal personal data with a single click. The security bypass that worked for five months? Tell the AI to do everything twice. Microsoft has spent $80 billion on AI infrastructure and plans $120 billion more for 2026, but the safeguards protecting your data failed against a one-line prompt. 🤔

Varonis Threat Labs discovered a way to steal personal data from Microsoft Copilot using nothing more than a single click on a link, with no plugins required and no further user interaction needed. The attack continues running even after the victim closes the browser tab.

In January 2026, Microsoft had already patched 114 vulnerabilities! Four modem drivers deleted since October. Companies that wrote them: gone. Source code: inaccessible. Microsoft’s only option: remove them entirely. Meanwhile, ransomware groups are loading over 900 other vulnerable drivers that still ship with Windows. 😱 Hackers discovered they could use a 20-year-old telephone code to take over any Windows machine. No hardware required.

One vulnerability stood out: CVE-2023-31096. A CVE number from 2023. Fixed in 2026. Three years later.

SAP just patched four critical vulnerabilities

SAP just patched four critical vulnerabilities. CVSS scores up to 9.9. One lets attackers run code with nothing but a malicious link. 425,000 companies run SAP. Over 85% of Fortune 500. The patches dropped today, January 13, 2026. 🧐

SAP Patch Tuesday just landed with seventeen security notes. Four are HotNews - SAP’s term for patch immediately or accept the consequences.

The most severe vulnerability lets someone with a basic user account run arbitrary SQL queries against the entire financial database.

Your iPhone can be compromised by loading a webpage. No click. No download. Just visit the wrong site. Apple patched this a month ago. Only 16% of users have updated. 🤔

StatCounter data from January 2026:

→ iOS 26 (all versions): 16% of iPhones

→ iOS 18 (unpatched): over 60% of iPhones

For comparison, iOS 18 reached 63% adoption by January 2025. iOS 26 is at less than one quarter of that rate. The lowest adoption Apple has seen in years.

A 52-year-old tape just revealed a buffer overflow that looks exactly like the bugs we’re still finding today. 😏

In July 2025, someone found a magnetic tape from 1973 in a storage room at the University of Utah. Handwritten on the label: “UNIX Original From Bell Labs V4”. This turned out to be the only surviving copy of Unix v4, the 1973 version where Ken Thompson and Dennis Ritchie rewrote the entire operating system from assembly into C.

100,000 servers. One HTTP header change. Full admin access. No password required. They call it “Ni8mare.” CVSS 10.0. The patch existed for 7 weeks. The release notes mentioned nothing. 😏

CVE-2026-21858. “Ni8mare” The name says it all.

n8n is a workflow automation platform. Think Zapier, but open source and self-hosted. Over 100 million Docker pulls. Used by Vodafone, Delivery Hero, StepStone. Thousands of enterprises run their entire automation infrastructure on it, with 400+ integrations connecting everything in one central hub.
