Microsoft and CrowdStrike have announced that they are teaming up to align their individual threat actor taxonomies by publishing a new joint threat actor mapping. "By mapping where our knowledge of these actors align, we will provide security professionals with the ability to connect insights faster and make decisions with greater confidence," Vasu Jakkal, corporate vice president at Microsoft Security, said . The initiative is seen as a way to untangle the menagerie of nicknames that private cybersecurity vendors assign to various hacking groups that are broadly categorized as a nation-state, financially motivated, influence operations, private sector offensive actors, and emerging clusters. For example, the Russian state-sponsored threat actor tracked by Microsoft as Midnight Blizzard (formerly Nobelium) is also known as APT29, BlueBravo, Cloaked Ursa, Cozy Bear, Iron Hemlock, and The Dukes. Likewise, Forest Blizzard (previously Strontium) goes by other monikers such...

It's not enough to be secure. In today's legal climate, you need to prove it. Whether you're protecting a small company or managing compliance across a global enterprise, one thing is clear: cybersecurity can no longer be left to guesswork, vague frameworks, or best-effort intentions. Regulators and courts are now holding organizations accountable for how "reasonable" their security programs are—and that's not just a buzzword anymore. But what does " reasonable" even mean in cybersecurity? That's exactly what this free webinar  we hosted with the experts from Center for Internet Security (CIS) will help you answer. New privacy laws, ransomware lawsuits, and regulatory investigations are raising the bar for cybersecurity expectations. If your defense program can't show structure, strategy, and measurable maturity, you're not just at risk—you're already falling behind. This isn't about hype. It's about legal risk, operational readiness, and your reputation. In this...

In cybersecurity, confidence is a double-edged sword. Organizations often operate under a false sense of security , believing that patched vulnerabilities, up-to-date tools, polished dashboards, and glowing risk scores guarantee safety. The reality is a bit of a different story. In the real world, checking the right boxes doesn't equal being secure. As Sun Tzu warned, "Strategy without tactics is the slowest route to victory. Tactics without strategy is the noise before defeat." Two and a half millennia later, the concept still holds: your organization's cybersecurity defenses must be strategically validated under real-world conditions to ensure your business's very survival. Today, more than ever, you need Adversarial Exposure Validation (AEV) , the essential strategy that's still missing from most security frameworks. The Danger of False Confidence Conventional wisdom suggests that if you've patched known bugs, deployed a stack of well-regarded security tools, and passed the nec...

Cyber threats are growing more sophisticated, and traditional security approaches struggle to keep up. Organizations can no longer rely on periodic assessments or static vulnerability lists to stay secure. Instead, they need a dynamic approach that provides real-time insights into how attackers move through their environment. This is where attack graphs come in. By mapping potential attack paths, they offer a more strategic way to identify and mitigate risk. In this article, we'll explore the benefits, types, and practical applications of attack graphs. Understanding Attack Graphs An attack graph is a visual representation of potential attack paths within a system or network. It maps how an attacker could move through different security weaknesses - misconfigurations, vulnerabilities, and credential exposures, etc. - to reach critical assets. Attack graphs can incorporate data from various sources, continuously update as environments change, and model real-world attack scenarios. ...

Is AI really reshaping the cyber threat landscape, or is the constant drumbeat of hype drowning out actual, more tangible, real-world dangers? According to Picus Labs' Red Report 2025 which analyzed over one million malware samples, there's been no significant surge, so far, in AI-driven attacks. Yes, adversaries are definitely continuing to innovate, and while AI will certainly start playing a larger and larger role, the latest data suggests that a set of well-known tactics, techniques, and procedures (TTPs) are still dominating the field. The hype around artificial intelligence has certainly been dominating media headlines; yet the real-world data paints a far more nuanced picture of which malware threats are thriving, and why. Here's a glimpse at the most critical findings and trends shaping the year's most deployed adversarial campaigns and what steps cybersecurity teams need to take to respond to them. Why the AI Hype is Falling Short…at Least For Now While headl...

Across small-to-medium enterprises (SMEs) and managed service providers (MSPs), the top priority for cybersecurity leaders is to keep IT environments up and running. To guard against cyber threats and prevent data breaches, it's vital to understand the current cybersecurity vendor landscape and continually assess the effectiveness of available solutions. Luckily, the 2024 MITRE ATT&CK Evaluation — the most widely trusted resource to track which solutions are effective — is now available. This practical guide distills key takeaways and advice to interpret the results. Cynet was the only vendor to achieve 100% Visibility and 100% Protection in the 2024 Evaluation. That means the All-in-One Cybersecurity Platform detected 100% of the threats tested in the Detection Phase and blocked 100% of the attacks simulated in the Protection Phase of the Evaluation. Moreover, Cynet achieved the 100% detection with no false positives. "These 2024 MITRE ATT&CK Evaluation results reflect o...

A joint advisory issued by Australia, Canada, New Zealand, and the U.S. has warned of a broad cyber espionage campaign undertaken by People's Republic of China (PRC)-affiliated threat actors targeting telecommunications providers. "Identified exploitations or compromises associated with these threat actors' activity align with existing weaknesses associated with victim infrastructure; no novel activity has been observed," government agencies said . U.S. officials told Tuesday that the threat actors are still lurking inside U.S. telecommunications networks about six months after an investigation into the intrusions commenced. The attacks have been attributed to a nation-state group from China referred to as Salt Typhoon, which overlaps with activities tracked as Earth Estries, FamousSparrow, GhostEmperor, and UNC2286. The group is known to be active since at least 2020, with some of the artifacts developed as early as 2019. Last week, T-Mobile acknowledged that...

Multi-stage cyber attacks, characterized by their complex execution chains, are designed to avoid detection and trick victims into a false sense of security. Knowing how they operate is the first step to building a solid defense strategy against them. Let's examine real-world examples of some of the most common multi-stage attack scenarios that are active right now. URLs and Other Embedded Content in Documents Attackers frequently hide malicious links within seemingly legitimate documents, such as PDFs or Word files. Upon opening the document and clicking the embedded link, users are directed to a malicious website. These sites often employ deceptive tactics to get the victim to download malware onto their computer or share their passwords. Another popular type of embedded content is QR codes. Attackers conceal malicious URLs within QR codes and insert them into documents. This strategy forces users to turn to their mobile devices to scan the code, which then directs them to ph...

As a relatively new security category, many security operators and executives I've met have asked us "What are these Automated Security Validation (ASV) tools?" We've covered that pretty extensively in the past, so today, instead of covering the " What is ASV?" I wanted to address the " Why ASV?" question. In this article, we'll cover some common use cases and misconceptions of how people misuse and misunderstand ASV tools daily (because that's a lot more fun). To kick things off, there's no place to start like the beginning. Automated security validation tools are designed to provide continuous, real-time assessment of an organization's cybersecurity defenses. These tools are continuous and use exploitation to validate defenses like EDR, NDR, and WAFs. They're more in-depth than vulnerability scanners because they use tactics and techniques that you'll see in manual penetration tests. Vulnerability scanners won't relay hashes or combine vulnerabilities to further attacks, whic...

Budget season is upon us, and everyone in your organization is vying for their slice of the pie. Every year, every department has a pet project that they present as absolutely essential to profitability, business continuity, and quite possibly the future of humanity itself. And no doubt that some of these actually may be mission critical. But as cybersecurity professionals, we understand that the rollout of a viable CTEM ( Continuous Threat Exposure Management ) program actually is . In any year, cybersecurity investments are tough budgetary sells – they're hard to quantify and don't always clearly drive revenues or cut costs. In today's belt-tightening climate, all the more so. Even though cybersecurity budgets will likely grow this year according to Forrester, it's still important to make sure today that CTEM doesn't slip down the budget priority list.  In this article, we'll discuss how to keep CTEM on the budgetary radar. But First – Here are Some Reasons Why CTEM is Obje...

Cybersecurity researchers have discovered a new version of a well-known Android malware family dubbed FakeCall that employs voice phishing (aka vishing) techniques to trick users into parting with their personal information. "FakeCall is an extremely sophisticated Vishing attack that leverages malware to take almost complete control of the mobile device, including the interception of incoming and outgoing calls," Zimperium researcher Fernando Ortega said in a report published last week. "Victims are tricked into calling fraudulent phone numbers controlled by the attacker and mimicking the normal user experience on the device." FakeCall, also tracked under the names FakeCalls and Letscall, has been the subject of multiple analyses by Kaspersky, Check Point , and ThreatFabric since its emergence in April 2022. Previous attack waves have primarily targeted mobile users in South Korea. The names of the malicious package names, i.e., dropper apps, bearing the ma...
