Three different organizations in the U.S. were targeted in August 2024 by a North Korean state-sponsored threat actor called Andariel as part of a likely financially motivated attack. "While the attackers didn't succeed in deploying ransomware on the networks of any of the organizations affected, it is likely that the attacks were financially motivated," Symantec, part of Broadcom, said in a report shared with The Hacker News. Andariel is a threat actor that's assessed to be a sub-cluster within the infamous Lazarus Group. It's also tracked as APT45, DarkSeoul, Nickel Hyatt, Onyx Sleet (formerly Plutonium), Operation Troy, Silent Chollima, and Stonefly. It's been active since at least 2009. An element within North Korea's Reconnaissance General Bureau (RGB), the hacking crew has a track record of deploying ransomware strains such as SHATTEREDGLASS and Maui , while also developing an arsenal of custom backdoors like Dtrack (aka Valefor and Preft),

Many businesses rely on the Common Vulnerability Scoring System (CVSS) to assess the severity of vulnerabilities for prioritization. While these scores provide some insight into the potential impact of a vulnerability, they don't factor in real-world threat data, such as the likelihood of exploitation. With new vulnerabilities discovered daily, teams don't have the time - or the budget - to waste on fixing vulnerabilities that won't actually reduce risk. Read on to learn more about how CVSS and EPSS compare and why using EPSS is a game changer for your vulnerability prioritization process.  What is vulnerability prioritization? Vulnerability prioritization is the process of evaluating and ranking vulnerabilities based on the potential impact they could have on an organization. The goal is to help security teams determine which vulnerabilities should be addressed, in what timeframe, or if they need to be fixed at all. This process ensures that the most critical risks are mitigated b

For years, securing a company's systems was synonymous with securing its "perimeter." There was what was safe "inside" and the unsafe outside world. We built sturdy firewalls and deployed sophisticated detection systems, confident that keeping the barbarians outside the walls kept our data and systems safe. The problem is that we no longer operate within the confines of physical on-prem installations and controlled networks. Data and applications now reside in distributed cloud environments and data centers, accessed by users and devices connecting from anywhere on the planet. The walls have crumbled, and the perimeter has dissolved, opening the door to a new battlefield: identity . Identity is at the center of what the industry has praised as the new gold standard of enterprise security: "zero trust." In this paradigm, explicit trust becomes mandatory for any interactions between systems, and no implicit trust shall subsist. Every access request, regardless of its origin,

Cybersecurity researchers have flagged the discovery of a new post-exploitation red team tool called Splinter in the wild. Palo Alto Networks Unit 42 shared its findings after it discovered the program on several customers' systems. "It has a standard set of features commonly found in penetration testing tools and its developer created it using the Rust programming language," Unit 42's Dominik Reichel said . "While Splinter is not as advanced as other well-known post-exploitation tools like Cobalt Strike, it still presents a potential threat to organizations if it is misused." Penetration testing tools are often used for red team operations to flag potential security issues in a company's network. However, such adversary simulation tools can also be weaponized by threat actors to their advantage.  Unit 42 said it has not detected any threat actor activity associated with the Splinter tool set. There is no information as yet on who developed the t

The evolution of software always catches us by surprise. I remember betting against the IBM computer Deep Blue during its chess match against the grandmaster Garry Kasparov in 1997, only to be stunned when the machine claimed victory. Fast forward to today, would we have imagined just three years ago that a chatbot could write essays, handle customer support calls, and even craft commercial artwork? We continue to be amazed by what software can achieve—tasks we once thought were strictly human domains. Such is the surprise unfolding in the sphere of cybersecurity testing. Hold tight! Demystifying Penetration Testing If someone had told me 10 years ago that computer software could one day perform the work of an ethical hacker, I would have said 'No way, Jose'. Penetration testing—PT for short—is when experts mimic hackers to test a company's defenses. It's a critical practice, mandated by major regulatory bodies like PCI DSS, HIPAA, and DORA to ensure network safety. Yet, despite

The threat actor tracked as Mustang Panda has refined its malware arsenal to include new tools in order to facilitate data exfiltration and the deployment of next-stage payloads, according to new findings from Trend Micro. The cybersecurity firm, which is monitoring the activity cluster under the name Earth Preta, said it observed "the propagation of PUBLOAD via a variant of the worm HIUPAN." PUBLOAD is a known downloader malware linked to Mustang Panda since early 2022, deployed as part of cyber attacks targeting government entities in the Asia-Pacific (APAC) region to deliver the PlugX malware . "PUBLOAD was also used to introduce supplemental tools into the targets' environment, such as FDMTP to serve as a secondary control tool, which was observed to perform similar tasks as that of PUBLOAD; and PTSOCKET, a tool used as an alternative exfiltration option," security researchers Lenart Bermejo, Sunny Lu, and Ted Lee said. Mustang Panda's use of re

The proliferation of cybersecurity tools has created an illusion of security. Organizations often believe that by deploying a firewall, antivirus software, intrusion detection systems, identity threat detection and response , and other tools, they are adequately protected. However, this approach not only fails to address the fundamental issue of the attack surface but also introduces dangerous third-party risk to the mix. The world of cybersecurity is in a constant state of flux, with cybercriminals becoming increasingly sophisticated in their tactics. In response, organizations are investing heavily in cybersecurity tools, hoping to build an impenetrable fortress around their digital assets. However, the belief that adding "just one more cybersecurity tool" will magically fix your attack surface and enhance your protection is a dangerous misconception. The limitations of cybersecurity tools Cybersecurity tools, while essential, have inherent limitations. They are designe

The FBI and CISA Issue Joint Advisory on New Threats and How to Stop Ransomware Note: on August 29, the FBI and CISA issued a joint advisory as part of their ongoing #StopRansomware effort to help organizations protect against ransomware. The latest advisory, AA24-242A , describes a new cybercriminal group and its attack methods. It also details three important actions to take today to mitigate cyber threats from ransomware – Installing updates as soon as they are released, requiring phishing-resistant MFA (i.e. non-SMS text-based), and training users. The growth in the number of victims of ransomware attacks and data breaches has become so profound that the new cyber defense challenge is just keeping up with the number of new attacks and disclosures from victims. This is the product of stunning advancements in cybercriminal attack methods combined with a too-slow response by many organizations in adjusting to new attack methods. As predicted, Generative AI has indeed been a game ch

Simply relying on traditional password security measures is no longer sufficient. When it comes to protecting your organization from credential-based attacks, it is essential to lock down the basics first. Securing your Active Directory should be a priority – it is like making sure a house has a locked front door before investing in a high-end alarm system. Once the fundamentals are covered, look at how integrating external attack surface management (EASM) can significantly augment your password security, offering a robust shield against potential cyber threats and breaches.  First Secure Your Active Directory IT administrators should not just adhere to the minimum password policy standards by including complexity mandates. To enhance Active Directory security, they should enforce a policy that prohibits users from generating feeble passwords and incorporate a tool to detect and block the use of compromised passwords. passwords and adding a solution that can check for the use of co

The China-backed threat actor known as Earth Baku has diversified its targeting footprint beyond the Indo-Pacific region to include Europe, the Middle East, and Africa starting in late 2022. Newly targeted countries as part of the activity include Italy, Germany, the U.A.E., and Qatar, with suspected attacks also detected in Georgia and Romania. Governments, media and communications, telecoms, technology, healthcare, and education are some of the sectors singled out as part of the intrusion set. "The group has updated its tools, tactics, and procedures (TTPs) in more recent campaigns, making use of public-facing applications such as IIS servers as entry points for attacks, after which they deploy sophisticated malware toolsets on the victim's environment," Trend Micro researchers Ted Lee and Theo Chen said in an analysis published last week. The findings build upon recent reports from Zscaler and Google-owned Mandiant , which also detailed the threat actor's u

Traditionally, the focus has been on defending against digital threats such as malware, ransomware, and phishing attacks by detecting them and responding. However, as cyber threats become more sophisticated. There is a growing recognition of the importance of measures that stop new attacks before they are recognized. With high-value assets, it's not good enough to have the protection, it's essential to have some assurance that the protection is effective. With software, that assurance is hard work, and this has led to a complimentary approach, called hardsec. What is Hardsec? Short for " Hardware Security ." Hardsec is about using hardware logic and electronics to implement a security defence, rather than through software alone - thereby providing a higher level of security assurance and resilience against both external and insider threats . Making it an essential component of comprehensive cybersecurity strategies. The Rise of Sophisticated Attacks When the impact of an attack ag

The last few years have seen more than a few new categories of security solutions arise in hopes of stemming a never-ending tidal wave of risks. One of these categories is Automated Security Validation (ASV), which provides the attacker's perspective of exposures and equips security teams to continuously validate exposures, security measures, and remediation at scale. ASV is an important element of any cybersecurity strategy and by providing a clearer picture of potential vulnerabilities and exposures in the organization, security teams can identify weaknesses before they can be exploited.  However, relying solely on ASV can be limiting. In this article, we'll take a look into how combining the detailed vulnerability insights from  ASV  with the broader threat landscape analysis provided by the Continuous Threat Exposure Management Framework (CTEM) can empower your security teams to make more informed decisions and allocate resources effectively.
