Cybersecurity researchers have disclosed what they say is the "first native Spectre v2 exploit" against the Linux kernel on Intel systems that could be exploited to read sensitive data from the memory. The exploit, called Native Branch History Injection (BHI), can be used to leak arbitrary kernel memory at 3.5 kB/sec by bypassing existing Spectre v2/BHI mitigations, researchers from Systems and Network Security Group (VUSec) at Vrije Universiteit Amsterdam  said  in a new study. The shortcoming is being tracked as  CVE-2024-2201 . BHI was  first disclosed  by VUSec in March 2022, describing it as a technique that can get around Spectre v2 protections in modern processors from Intel, AMD, and Arm. While the attack leveraged extended Berkeley Packet Filters (eBPFs), Intel's recommendations to address the problem, among other things, were to disable Linux's unprivileged eBPFs. "Privileged managed runtimes that can be configured to allow an unprivileged user ...

Cyber security of many organizations being attacked at an extremely high rate this month, well another alarming cyber crime report become public today. A widely unpatched and two years old critical vulnerability in JBoss Application Server (AS) that enable an attacker to remotely get a shell on a vulnerable web server. JBoss Application Server is an open-source Java EE-based application server very popular, it was designed by JBoss, now a division of Red Hat. In late 2012, JBoss AS was named as " wildFly ", since disclosure of the exploit code many products running the affected JBoss Application Server have been impacted, including some security software. Tens of thousands of enterprise data center servers are vulnerable to this attack, with at least 500 actively compromised, according to the Imperva report. Many systems administrators have yet to properly configure their servers to mitigate the threat, and the number of potential targets has increased over...

A few days ago, a friend and I were having a rather engaging conversation that sparked my excitement. We were discussing my prospects of becoming a red teamer as a natural career progression. The reason I got stirred up is not that I want to change either my job or my position, as I am a happy camper being part of Cymulate's blue team. What upset me was that my friend could not grasp the idea that I wanted to keep working as a blue teamer because, as far as he was concerned, the only natural progression is to move to the red team.  Red teams include many roles ranging from penetration testers to attackers and exploit developers. These roles attract most of the buzz, and the many certifications revolving around these roles (OSCP, OSEP, CEH) make them seem fancy. Movies usually make hackers the heroes, while typically ignoring the defending side, the complexities and challenges of blue teamers' roles are far less known. While blue teams' defending roles might not sound as...

Cisco has released security fixes to address multiple security flaws, including a critical bug, that could be exploited by a threat actor to take control of an affected system or cause a denial-of service (DoS) condition. The most severe of the issues is CVE-2023-20238, which has the maximum CVSS severity rating of 10.0. It’s described as an authentication bypass flaw in the Cisco BroadWorks Application Delivery Platform and Cisco BroadWorks Xtended Services Platform. Successful exploitation of the vulnerability -- a weakness in the single sign-on (SSO) implementation and discovered during internal testing -- could allow an unauthenticated, remote attacker to forge the credentials required to access an affected system. “This vulnerability is due to the method used to validate SSO tokens,” Cisco  said . “An attacker could exploit this vulnerability by authenticating to the application with forged credentials. A successful exploit could allow the attacker to commit toll fraud or ...

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, ...

Monday’s recap shows the same pattern in different places. A third-party tool becomes a way in, then leads to internal access. A trusted download path is briefly swapped to deliver malware. Browser extensions act normally while pulling data and running code. Even update channels are used to push payloads. It’s not breaking systems—it’s bending trust. There’s also a shift in how attacks run. Slower check-ins, multi-stage payloads, andmore code kept in memory. Attackers lean on real tools and normal workflows instead of custom builds. Some cases hint at supply-chain spread, where one weak link reaches further than expected. Go through the whole recap. The pattern across access, execution, and control only shows up when you see it all together. ⚡ Threat of the Week Vercel Discloses Data Breach —Web infrastructure provider Vercel has disclosed a security breach that allows bad actors to gain unauthorized access to "certain" internal Vercel systems. The incident originated f...

Another week in cybersecurity. Another week of "you've got to be kidding me." Attackers were busy. Defenders were busy. And somewhere in the middle, a whole lot of people had a very bad Monday morning. That's kind of just how it goes now. The good news? There were some actual wins this week. Real ones. The kind where the good guys showed up, did the work, and made a dent. It doesn't always happen, so when it does, it's worth noting. The bad news? For every win, there's a fresh headache waiting right behind it. New tricks, old tricks dressed up in new clothes, and a few things that'll make you want to go touch grass and never log back in. But you will. We all do. So here's everything that mattered this week — the wins, the warnings, and the stuff you really shouldn't ignore. ⚡ Threat of the Week Tycoon 2FA and LeakBase Operations Dismantled — The infrastructure hosting the Tycoon2FA service, which Europol said was among the largest advers...

In a post shared on LinkedIn, Charles Carmakal, CTO of Mandiant at Google Cloud, said "Cl0p exploited multiple vulnerabilities in Ora...

U.S. cybersecurity and intelligence agencies have issued a joint advisory warning of potential cyber attacks from Iranian state-sponsored or affiliated threat actors.  "Over the past several months, there has been increasing activity from hacktivists and Iranian government-affiliated actors, which is expected to escalate due to recent events," the agencies said . "These cyber actors often exploit targets of opportunity based on the use of unpatched or outdated software with known Common Vulnerabilities and Exposures or the use of default or common passwords on internet-connected accounts and devices." There is currently no evidence of a coordinated campaign of malicious cyber activity in the U.S. that can be attributed to Iran, the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), the Department of Defense Cyber Crime Center (DC3), and the National Security Agency (NSA) noted. Emphasizing the need for "incr...

Security news rarely moves in a straight line. This week, it feels more like a series of sharp turns, some happening quietly in the background, others playing out in public view. The details are different, but the pressure points are familiar. Across devices, cloud services, research labs, and even everyday apps, the line between normal behavior and hidden risk keeps getting thinner. Tools meant to protect, update, or improve systems are also becoming pathways when something goes wrong. This recap gathers the signals in one place. Quick reads, real impact, and developments that deserve a closer look before they become next week’s bigger problem. ⚡ Threat of the Week Dell RecoverPoint for VMs Zero-Day Exploited — A maximum severity security vulnerability in Dell RecoverPoint for Virtual Machines has been exploited as a zero-day by a suspected China-nexus threat cluster dubbed UNC6201 since mid-2024.

You wouldn’t run your blue team once a year, so why accept this substandard schedule for your offensive side? Your cybersecurity teams are under intense pressure to be proactive and to find your network’s weaknesses before adversaries do. But in many organizations, offensive security is still treated as a one-time event: an annual pentest, a quarterly red team engagement, maybe an audit sprint before a compliance deadline . That’s not defense. It's a theater. In the real world, adversaries don’t operate in bursts. Their recon is continuous, their tools and tactics are always evolving, and new vulnerabilities are often reverse-engineered into working exploits within hours of a patch release.  So, if your offensive validation isn’t just as dynamic, you’re not just lagging, you’re exposed. It’s time to move beyond the once a year pentest. It’s time to build an Offensive Security Operations Center . Why annual pentesting falls short Point-in-time penetration tests still serv...

What if attackers aren't breaking in—they're already inside, watching, and adapting? This week showed a sharp rise in stealth tactics built for long-term access and silent control. AI is being used to shape opinions. Malware is hiding inside software we trust. And old threats are returning under new names. The real danger isn’t just the breach—it’s not knowing who’s still lurking in your systems. If your defenses can’t adapt quickly, you're already at risk. Here are the key cyber events you need to pay attention to this week. ⚡ Threat of the Week Lemon Sandstorm Targets Middle East Critical Infra — The Iranian state-sponsored threat group tracked as Lemon Sandstorm targeted an unnamed critical national infrastructure (CNI) in the Middle East and maintained long-term access that lasted for nearly two years using custom backdoors like HanifNet, HXLibrary, and NeoExpressRAT. The activity, which lasted from at least May 2023 to February 2025, entailed "extensive es...

In cybersecurity, precision matters—and there’s little room for error. A small mistake, missed setting, or quiet misconfiguration can quickly lead to much bigger problems. The signs we’re seeing this week highlight deeper issues behind what might look like routine incidents: outdated tools, slow response to risks, and the ongoing gap between compliance and real security. For anyone responsible for protecting systems, the key isn’t just reacting to alerts—it’s recognizing the larger patterns and hidden weak spots they reveal. Here’s a breakdown of what’s unfolding across the cybersecurity world this week. ⚡ Threat of the Week NCA Arrests for Alleged Scattered Spider Members — The U.K. National Crime Agency (NCA) announced that four people have been arrested in connection with cyber attacks targeting major retailers Marks & Spencer, Co-op, and Harrods.
