May 28, 2026 Hacking News / Cybersecurity News
Every time you think the industry has finally stopped doing some reckless, low-effort crap, somebody spins up a fresh box full of sketchy loaders, fake installers, recycled social-engineering bait, and enough exposed infrastructure to make you wonder if prod is just a public beta now - meanwhile some researcher casually drops a technique that turns a "minor" foothold into total account compromise because apparently six digits and blind trust were all that stood between your vault and getting absolutely pwned. Cool. Great. Love that for us. Then there's the supply chain mess... signed binaries, poisoned updates, legit tooling getting hijacked like it's still 2017, plus a few reports this week that feel less like advanced tradecraft and more like watching skiddies discover low-hanging fruit with enterprise branding slapped on top. The weird part isn't that it works. The weird part is how damn easy it still is. Anyway. Grab caffeine. Let's get into it. ...
ThreatsDay Bulletin: Linux Rootkits, Router 0-Day, AI Intrusions, Scam Kits and 25 New Stories

ThreatsDay Bulletin: Linux Rootkits, Router 0-Day, AI Intrusions, Scam Kits and 25 New Stories

May 21, 2026 Hacking News / Cybersecurity News
This week starts small. A token leaks. A bad package slips in. A login trick works. An old tool shows up again. At first, it feels like the usual mess. Then you see the pattern: attackers are not always breaking in. They are using the parts we already trust. That is what makes it worrying. The danger is in normal things now - updates, apps, cloud buttons, support chats, trusted accounts. AI does not make the attacks magic. It just helps people try more things, faster. Here's what showed up this week. 47 zero-days exposed 47 0-Days Discovered in Pwn2Own Berlin 2026 The Pwn2Own Berlin 2026 hacking contest has concluded, with security researchers collecting $1,298,250 in rewards after exploiting 47 zero-day flaws in various products from Windows, Linux, VMware, and NVIDIA. DEVCORE won the event with 50.5 Master of Pwn points and $505,000 in rewards throughout the three-day contest after hacking Microsoft SharePoint, Microsoft E...

May 14, 2026 Hacking News / Cybersecurity News
Everything is still on fire. This week feels dumb in the worst way — bad links, weak checks, fake help desks, shady forum posts, and people turning supply chain attacks into some cursed little game for clout and cash. Half of it feels new. Half of it feels like crap we should have fixed years ago. The mess keeps getting louder: users get tricked, boxes get popped, tools meant for normal work get used for bad stuff, and nobody seems shocked anymore. Great. Love that for us. Anyway. Let’s get into it. Exploited PAN-OS RCE Palo Alto Networks Releases Fixes for Exploited Flaw Palo Alto Networks has released the first round of fixes to address CVE-2026-0300 , a critical buffer overflow vulnerability in the User-ID Authentication Portal service of PAN-OS software that could allow an unauthenticated attacker to execute arbitrary code with root privileges by sending specially crafted packets. The company said it has observed the flaw being...

May 07, 2026 Hacking News / Cybersecurity News
Bad week. Turns out the easiest way to get hacked in 2026 is still the same old garbage: shady packages, fake apps, forgotten DNS junk, scam ads, and stolen logins getting dumped into Discord channels like it’s normal. Some of these attack chains don’t even feel sophisticated anymore. More like some tired guy with a Telegram account and too much free time. The worst part is how often this stuff still works. Meanwhile, AI tools are speeding up exploit hunting, browsers are keeping passwords sitting in memory for “performance reasons,” and even ransomware crews are pushing broken builds into the wild. Everybody’s scrambling to patch faster because attackers are automating faster. Anyway. ThreatsDay’s rough this week. Let’s get into it. Credential theft campaign New MicroStealer Spotted A new stealer called MicroStealer has been observed targeting education and telecom sectors to steal sensitive data. It was first observed in the wild in...

Apr 30, 2026 Hacking News / Cybersecurity News
The internet is noisy this week. We are seeing some wild new tactics, like people using fake cell towers to send scam texts, while some developers are accidentally downloading tools that peek into their private files during a simple install. It is definitely a busy time to be online. Security is always a moving target. Millions of servers are currently sitting online without any passwords, and old software bugs are showing up in the most unexpected places. Even with the right fixes available, staying one step ahead is a full-time job for all of us. Data is shifting in strange ways, too. Some browser tools are now legally selling user history for profit, and new kits are making it simpler for almost anyone to launch a campaign. You have to see these latest updates to believe them. Let’s look at the full list... SMS blaster phishing crackdown Canadian Authorities Arrest 3 Men for Alleged Use of SMS Blaster Canadian authorities have ar...

Apr 23, 2026 Hacking News / Cybersecurity News
You scroll past one incident and see another that feels familiar, like it should have been fixed years ago, but it still works with small changes. Same bugs. Same mistakes. The supply chain is messy. Packages you did not check are stealing data, adding backdoors, and spreading. Attacking the systems behind apps is easier than breaking the apps themselves. The exploits are simple but still work, giving attackers easy access. AI tools are also part of the problem now. They trust bad input and take real actions, which makes the damage bigger. Then there are quieter issues. Apps take data they should not. Devices behave in strange ways. Attackers keep testing what they can get away with. No noise. Just ongoing damage. Here is the list for this week’s ThreatsDay Bulletin. State-backed crypto heist North Korea Likely Behind KelpDAP $290M Crypto Heist Inter-blockchain communication protocol LayerZero has revealed that North Korean thr...

Apr 16, 2026 Hacking News / Cybersecurity News
You know that feeling when you open your feed on a Thursday morning and it's just... a lot? Yeah. This week delivered. We've got hackers getting creative in ways that are almost impressive if you ignore the whole "crime" part, ancient vulnerabilities somehow still ruining people's days, and enough supply chain drama to fill a season of television nobody asked for. Not all bad though. Some threat actors got exposed with receipts, a few platforms finally tightened things up, and there's research in here that's genuinely worth your time. Grab your coffee and keep scrolling. Targeted wallet breach Zerion Hack Likely Linked to North Korea Cryptocurrency wallet service Zerion has disclosed that one of its team member's devices was compromised, resulting in the theft of approximately $100K in stolen funds from internal company hot wallets. The company noted that user funds, Zerion apps, or infrastructure were...

Apr 09, 2026 Hacking News / Cybersecurity News
Thursday. Another week, another batch of things that probably should've been caught sooner but weren't. This one's got some range — old vulnerabilities getting new life, a few "why was that even possible" moments, attackers leaning on platforms and tools you'd normally trust without thinking twice. Quiet escalations more than loud zero-days, but the kind that matter more in practice anyway. Mix of malware, infrastructure exposure, AI-adjacent weirdness, and some supply chain stuff that's... not great. Let's get into it. Resilient hybrid botnet surge Phorpiex Botnet Detailed A new variant of the botnet known as Phorpiex (aka Trik) has been observed, using a hybrid communication model that combines traditional C2 HTTP polling with a peer-to-peer (P2P) protocol over both TCP and UDP to ensure operational continuity in the face of server takedowns. The malware acts as a conduit for encrypted payloads, ma...

ThreatsDay Bulletin: Pre-Auth Chains, Android Rootkits, CloudTrail Evasion & 10 More Stories

Apr 02, 2026 Cybersecurity / Hacking News
The latest ThreatsDay Bulletin is basically a cheat sheet for everything breaking on the internet right now. No corporate fluff or boring lectures here, just a quick and honest look at the messy reality of keeping systems safe this week. Things are moving fast. The list includes researchers chaining small bugs together to create massive backdoors, old software flaws coming back to haunt us, and some very clever new tricks that let attackers bypass security logs entirely without leaving a trace. We are also seeing sketchier traffic on the underground and the usual supply chain mess, where one bad piece of code threatens thousands of apps. It is definitely worth a quick scan before you log off for the day, if only to make sure none of this is sitting in your own network. Let's get into it.

ThreatsDay Bulletin: PQC Push, AI Vuln Hunting, Pirated Traps, Phishing Kits & 20 More Stories

Mar 26, 2026 Cybersecurity / Hacking News
Some weeks in security feel loud. This one feels sneaky. Less big dramatic fireworks, more of that slow creeping sense that too many people are getting way too comfortable abusing things they probably shouldn’t even be touching. There’s a little bit of everything in this one, too. Weird delivery tricks, old problems coming back in slightly worse forms, shady infrastructure doing shady infrastructure things, and the usual reminder that if criminals find a workflow annoying, they’ll just make a new one by Friday. Efficient little parasites. You almost have to respect the commitment. A few of these updates have that nasty “yeah, that tracks” energy. Stuff that sounds niche right up until you picture it landing in a real environment with real users clicking real nonsense because they’re busy and tired and just trying to get through the day. Then it stops being abstract pretty fast. So yeah, this week’s ThreatsDay Bulletin is a solid scroll-befor...

ThreatsDay Bulletin: FortiGate RaaS, Citrix Exploits, MCP Abuse, LiveChat Phish & More

Mar 19, 2026 Cybersecurity / Hacking News
ThreatsDay Bulletin is back on The Hacker News, and this week feels off in a familiar way. Nothing loud, nothing breaking everything at once. Just a lot of small things that shouldn’t work anymore but still do. Some of it looks simple, almost sloppy, until you see how well it lands. Other bits feel a little too practical, like they’re already closer to real-world use than anyone wants to admit. And the background noise is getting louder again, the kind people usually ignore. A few stories are clever in a bad way. Others are just frustratingly avoidable. Overall, it feels like quiet pressure is building in places that matter. Skim it or read it properly, but don’t skip this one. Emerging RaaS exploiting FortiGate flaws The Gentlemen RaaS Detailed Group-IB has shed light on the various tactics adopted by The Gentlemen, a nascent Ransomware-as-a-Service (RaaS) operation that consists of about 20 members. It originated f...

Mar 12, 2026 Cybersecurity / Hacking News
Another Thursday, another pile of weird security stuff that somehow happened in just seven days. Some of it is clever. Some of it is lazy. A few bits fall into that uncomfortable category of “yeah… this is probably going to show up in real incidents sooner than we’d like.” The pattern this week feels familiar in a slightly annoying way. Old tricks are getting polished. New research shows how flimsy certain assumptions really are. A couple of things that make you stop mid-scroll and think, “wait… people are actually pulling this off?” There’s also the usual mix of strange corners of the ecosystem doing strange things — infrastructure behaving a little too professionally for comfort, tools showing up where they absolutely shouldn’t, and a few cases where the weakest link is still just… people clicking stuff they probably shouldn’t. Anyway. If you’ve got five minutes and a mild curiosity about what attackers, researchers, and the broader internet gremlins were up to lately, this week’...
