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...
