A recently disclosed critical security flaw impacting CrushFTP has been added by the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to its Known Exploited Vulnerabilities ( KEV ) catalog after reports emerged of active exploitation in the wild. The vulnerability is a case of authentication bypass that could permit an unauthenticated attacker to take over susceptible instances. It has been fixed in versions 10.8.4 and 11.3.1. "CrushFTP contains an authentication bypass vulnerability in the HTTP authorization header that allows a remote unauthenticated attacker to authenticate to any known or guessable user account (e.g., crushadmin), potentially leading to a full compromise," CISA said in an advisory. The shortcoming has been assigned the CVE identifier CVE-2025-31161 (CVSS score: 9.8). It bears noting that the same vulnerability was previously tracked as CVE-2025-2825 , which has now been marked Rejected in the CVE list. The development comes after th...

Google has shipped patches for 62 vulnerabilities, two of which it said have been exploited in the wild. The two high-severity vulnerabilities are listed below - CVE-2024-53150 (CVSS score: 7.8) - An out-of-bounds flaw in the USB sub-component of Kernel that could result in information disclosure CVE-2024-53197 (CVSS score: 7.8) - A privilege escalation flaw in the USB sub-component of Kernel "The most severe of these issues is a critical security vulnerability in the System component that could lead to remote escalation of privilege with no additional execution privileges needed," Google said in its monthly security bulletin for April 2025. "User interaction is not needed for exploitation." The tech giant also acknowledged that both the shortcomings may have come under "limited, targeted exploitation." It's worth noting that CVE-2024-53197 is rooted in the Linux kernel and was patched last year, alongside CVE-2024-53104 and CVE-2024-50302...

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) records associated with a single domain name," the agencies said . "This threat exploits a gap commonly found in network defenses, making the tracking and blocking of malicious fast flux activities difficult." The advisory comes courtesy of the U.S. Cybersecurity and Infrastructure Security Agency (CISA), National Security Agency (NSA), Federal Bureau of Investigation (FBI), Australian Signals Directorate's Australian Cyber Security Centre, Canadian Centre for Cyber Security, and New Zealand's National Cyber Security Centre. Fast flux has been embraced by many...

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, we trace how simple oversights turn into major breaches — and the silent threats most companies still underestimate. Let's dive in. ⚡ Threat of the Week UNC5221 Exploits New Ivanti Flaw to Drop Malware — The China-nexus cyber espionage group tracked as UNC5221 exploited a now-patched flaw in Ivanti Connect Secure, CVE-2025-22457 (CVSS score: 9.0), to deliver an in-memory dropper called TRAILBLAZE, a passive backdoor codenamed BRUSHFIRE, and the SPAWN malware suite. The vulnerability was originally patched by Ivanti on February 11, 2025, indicating that the threat actors studied the patch a...

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 responded - but often vulnerability management metrics get associated with operational metrics because traditional approaches to measuring and implementing vulnerability management does not actually reduce risk. So, we resort to various ways of reporting on how many patches were applied under the traditional 30/60/90-day patching method . I call these vanity metrics : numbers that look impressive in reports but lack real-world impact. They offer reassurance, but not insights. Meanwhile, threats continue to grow more sophisticated, and attackers exploit the blind spots we're not measuring. I've se...

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 analysis. "As part of the attack, PoisonSeed provides security seed phrases to get potential victims to copy and paste them into new cryptocurrency wallets for future compromising." Targets of PoisonSeed include enterprise organizations and individuals outside the cryptocurrency industry. Crypto companies like Coinbase and Ledger, and bulk email providers such as Mailchimp, SendGrid, Hubspot, Mailgun, and Zoho are among the targeted crypto companies. The activity is assessed to be distinct from two loosely aligned threat actors Scattered Spider and CryptoChameleon , whi...

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 cybercriminal, who, about 10 years ago, fled his hometown in Kharkov, Ukraine, to a new place somewhere near the Romanian coast. The vulnerabilities were credited by Microsoft to a party named "SkorikARI with SkorikARI," which has been assessed to be another username used by EncryptHub. The flaws in question, both of which were fixed by Redmond as part of its Patch Tuesday update last month, are below - CVE-2025-24061 (CVSS score: 7.8) - Microsoft Windows Mark-of-the-Web (MotW) Security Feature Bypass Vulnerability CVE-2025-24071 (CVSS score: 6.5) - Microsoft Windo...

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. "These latest samples employ hexadecimal string encoding to evade automated detection systems and manual code audits, signaling a variation in the threat actors' obfuscation techniques," Socket security researcher Kirill Boychenko said in a report. The packages in question, which were collectively downloaded more than 5,600 times prior to their removal, are listed below - empty-array-validator twitterapis dev-debugger-vite snore-log core-pino events-utils icloud-cod cln-logger node-clog consolidate-log consolidate-logger The disclosure comes nearly a month after a set of six npm packages were discovered distributing BeaverTail , a JavaScript stealer that's also capable of delivering a Python-b...

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 by Socket, disgrasya, contained a fully automated carding script targeting WooCommerce stores. The packages attracted hundreds of downloads before being taken down, according to statistics from pepy.tech - bitcoinlibdbfix - 1,101 downloads bitcoinlib-dev - 735 downloads disgrasya - 37,217 downloads "The malicious libraries both attempt a similar attack, overwriting the legitimate 'clw cli' command with malicious code that attempts to exfiltrate sensitive database files," ReversingLabs said. In an interesting twist, the authors of the counterfeit libraries are s...

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. "The attackers obtained initial access by taking advantage of the GitHub Actions workflow of SpotBugs, a popular open-source tool for static analysis of bugs in code," Palo Alto Networks Unit 42 said in an update this week. "This enabled the attackers to move laterally between SpotBugs repositories, until obtaining access to reviewdog." There is evidence to suggest that the malicious activity began as far back as late November 2024, although the attack against Coinbase did not take place until March 2025. Unit 42 said its investigation began with the knowledge that reviewdog's GitHub Action was compromised due to a leaked PAT associated with the project's maintainer. This subsequen...

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 the innovation, and in turn, a new wave of innovators create the next generation of use cases, driving further advancements. Containerization has become the foundation of modern, cloud-native software development, supporting new use cases and approaches to building resilient, scalable, and portable applications. It also holds the keys to the next software delivery innovation, simultaneously necessitating the evolution to secure-by-design, continuously-updated software and serving as the means to get there. Below, I'll talk through some of the innovations that led to our containerized r...
