The Hacker News

Cybersecurity agencies from Australia, Canada, New Zealand, and the United States have published a joint advisory about the risks associated with a technique called fast flux that has been adopted by threat actors to obscure a command-and-control (C2) channel. "'Fast flux' is a technique used to obfuscate the locations of malicious servers through rapidly changing Domain Name System (DNS) Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

Today, every unpatched system, leaked password, and overlooked plugin is a doorway for attackers. Supply chains stretch deep into the code we trust, and malware hides not just in shady apps — but in job offers, hardware, and cloud services we rely on every day. Hackers don’t need sophisticated exploits anymore. Sometimes, your credentials and a little social engineering are enough. This week, Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

After more than 25 years of mitigating risks, ensuring compliance, and building robust security programs for Fortune 500 companies, I’ve learned that looking busy isn’t the same as being secure.  It’s an easy trap for busy cybersecurity leaders to fall into. We rely on metrics that tell a story of the tremendous efforts we’re expending - how many vulnerabilities we patched, how fast we [email protected]

A malicious campaign dubbed PoisonSeed is leveraging compromised credentials associated with customer relationship management (CRM) tools and bulk email providers to send spam messages containing cryptocurrency seed phrases in an attempt to drain victims' digital wallets. "Recipients of the bulk spam are targeted with a cryptocurrency seed phrase poisoning attack," Silent Push said in an Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

A likely lone wolf actor behind the EncryptHub persona was acknowledged by Microsoft for discovering and reporting two security flaws in Windows last month, painting a picture of a "conflicted" individual straddling a legitimate career in cybersecurity and pursuing cybercrime. In a new extensive analysis published by Outpost24 KrakenLabs, the Swedish security company unmasked the up-and-coming Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

The North Korean threat actors behind the ongoing Contagious Interview campaign are spreading their tentacles on the npm ecosystem by publishing more malicious packages that deliver the BeaverTail malware, as well as a new remote access trojan (RAT) loader.

Cybersecurity researchers have uncovered malicious libraries in the Python Package Index (PyPI) repository that are designed to steal sensitive information and test stolen credit card data. Two of the packages, bitcoinlibdbfix and bitcoinlib-dev, masquerade as fixes for recent issues detected in a legitimate Python module called bitcoinlib, according to ReversingLabs. A third package discovered Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

The cascading supply chain attack that initially targeted Coinbase before becoming more widespread to single out users of the "tj-actions/changed-files" GitHub Action has been traced further back to the theft of a personal access token (PAT) related to SpotBugs.

There’s a virtuous cycle in technology that pushes the boundaries of what’s being built and how it’s being used. A new technology development emerges and captures the world's attention. People start experimenting and discover novel applications, use cases, and approaches to maximize the innovation's potential. These use cases generate significant value, fueling demand for the next iteration of [email protected]

Ivanti has disclosed details of a now-patched critical security vulnerability impacting its Connect Secure product that has come under active exploitation in the wild. The vulnerability, tracked as CVE-2025-22457 (CVSS score: 9.0), concerns a case of a stack-based buffer overflow that could be exploited to execute arbitrary code on affected systems.

A novice cybercrime actor has been observed leveraging the services of a Russian bulletproof hosting (BPH) provider called Proton66 to facilitate their operations. The findings come from DomainTools, which detected the activity after it discovered a phony website named cybersecureprotect[.]com hosted on Proton66 that masqueraded as an antivirus service. The threat intelligence firm said it Ravie Lakshmananhttp://www.blogger.com/profile/[email protected]

The Computer Emergency Response Team of Ukraine (CERT-UA) has revealed that no less than three cyber attacks were recorded against state administration bodies and critical infrastructure facilities in the country with an aim to steal sensitive data.

The rules have changed. Again. Artificial intelligence is bringing powerful new tools to businesses. But it's also giving cybercriminals smarter ways to attack. They’re moving quicker, targeting more precisely, and slipping past old defenses without being noticed. And here's the harsh truth: If your security strategy hasn’t evolved with AI in mind, you’re already behind. But you’re not alone—[email protected]

AI holds the promise to revolutionize all sectors of enterpriseーfrom fraud detection and content personalization to customer service and security operations. Yet, despite its potential, implementation often stalls behind a wall of security, legal, and compliance hurdles.
