Aeternum C2 Botnet Stores Encrypted Commands on Polygon Blockchain to Evade Takedown

Aeternum C2 Botnet Stores Encrypted Commands on Polygon Blockchain to Evade Takedown

Feb 26, 2026 Malware / Blockchain
Cybersecurity researchers have disclosed details of a new botnet loader called Aeternum C2 that uses a blockchain-based command-and-control (C2) infrastructure to make it resilient to takedown efforts. "Instead of relying on traditional servers or domains for command-and-control, Aeternum stores its instructions on the public Polygon blockchain," Qrator Labs said in a report shared with The Hacker News. "This network is widely used by decentralized applications, including Polymarket, the world's largest prediction market. This approach makes Aeternum's C2 infrastructure effectively permanent and resistant to traditional takedown methods." This is not the first time botnets have been found relying on blockchain for C2. In 2021, Google said it took steps to disrupt a botnet known as Glupteba that uses the Bitcoin blockchain as a backup C2 mechanism to fetch the actual C2 server address. Details of Aeternum C2 first emerged in December 2025, when Outpos...
Bad Rabbit: New Ransomware Attack Rapidly Spreading Across Europe

Bad Rabbit: New Ransomware Attack Rapidly Spreading Across Europe

Oct 24, 2017
A new widespread ransomware attack is spreading like wildfire around Europe and has already affected over 200 major organisations, primarily in Russia, Ukraine, Turkey and Germany, in the past few hours. Dubbed " Bad Rabbit ," is reportedly a new Petya-like targeted ransomware attack against corporate networks, demanding 0.05 bitcoin (~ $285) as ransom from victims to unlock their systems. According to an initial analysis provided by the Kaspersky, the ransomware was distributed via drive-by download attacks, using fake Adobe Flash players installer to lure victims' in to install malware unwittingly. "No exploits were used, so the victim would have to manually execute the malware dropper, which pretends to be an Adobe Flash installer. We’ve detected a number of compromised websites, all of which were news or media websites." Kaspersky Lab said . However, security researchers at ESET have detected Bad Rabbit malware as ' Win32/Diskcoder.D ' —...

⚡ Weekly Recap — SharePoint Breach, Spyware, IoT Hijacks, DPRK Fraud, Crypto Drains and More

Jul 28, 2025
Some risks don’t breach the perimeter—they arrive through signed software, clean resumes, or sanctioned vendors still hiding in plain sight. This week, the clearest threats weren’t the loudest—they were the most legitimate-looking. In an environment where identity, trust, and tooling are all interlinked, the strongest attack path is often the one that looks like it belongs. Security teams are now challenged to defend systems not just from intrusions—but from trust itself being turned into a weapon. ⚡ Threat of the Week Microsoft SharePoint Attacks Traced to China — The fallout from an attack spree targeting defects in on-premises Microsoft SharePoint servers continues to spread a week after the discovery of the zero-day exploits, with more than 400 organizations globally compromised. The attacks have been attributed to two known Chinese hacking groups tracked as Linen Typhoon (aka APT27), Violet Typhoon (aka APT31), and a suspected China-based threat actor codenamed Storm-2603 t...

Behind every click, there’s a risk waiting to be tested. A simple ad, email, or link can now hide something dangerous. Hackers are getting smarter, using new tools to sneak past filters and turn trusted systems against us. But security teams are fighting back. They’re building faster defenses, better ways to spot attacks, and stronger systems to keep people safe. It’s a constant race — every move by attackers sparks a new response from defenders. In this week’s ThreatsDay Bulletin, we look at the latest moves in that race — from new malware and data leaks to AI tools, government actions, and major security updates shaping the digital world right now. U.K. moves to tighten cyber rules for key sectors U.K. Debuts Cyber Security and Resilience Bill The U.K. government has proposed a new Cyber Security and Resilience Bill that aims to strengthen national security and secure public services like healthcare, drinking wat...

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...

Welcome to this week’s Cybersecurity News Recap. Discover how cyber attackers are using clever tricks like fake codes and sneaky emails to gain access to sensitive data. We cover everything from device code phishing to cloud exploits, breaking down the technical details into simple, easy-to-follow insights. ⚡ Threat of the Week Russian Threat Actors Leverage Device Code Phishing to Hack Microsoft Accounts — Microsoft and Volexity have revealed that threat actors with ties to Russia are leveraging a technique known as device code phishing to gain unauthorized access to victim accounts, and use that access to get hold of sensitive data and enable persistent access to the victim environment. At least three different Russia-linked clusters have been identified abusing the technique to date. The attacks entail sending phishing emails that masquerade as Microsoft Teams meeting invitations, which, when clicked, urge the message recipients to authenticate using a threat actor-generated dev...

Another week, another reminder that the internet is still a mess. Systems people thought were secure are being broken in simple ways, showing many still ignore basic advisories. This edition covers a mix of issues: supply chain attacks hitting CI/CD setups, long-abused IoT devices being shut down, and exploits moving quickly from disclosure to real attacks. There are also new malware tricks showing attackers are becoming more patient and creative. It’s a mix of old problems that never go away and new methods that are harder to detect. There are quiet state-backed activities, exposed data from open directories, growing mobile threats, and a steady stream of zero-days and rushed patches. Grab a coffee, and at least skim the CVE list. Some of these are the kind you don’t want to discover after the damage is done. ⚡ Threat of the Week Trivy Vulnerability Scanner Breached in for Supply Chain Attack — Attackers have backdoored the widely used open-source Trivy vulnerability scanner, ...
