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. ...

A 19-year-old vulnerability has been re-discovered in the RSA implementation from at least 8 different vendors—including F5, Citrix, and Cisco—that can give man-in-the-middle attackers access to encrypted messages. Dubbed ROBOT ( Return of Bleichenbacher's Oracle Attack ), the attack allows an attacker to perform RSA decryption and cryptographic operations using the private key configured on the vulnerable TLS servers. ROBOT attack is nothing but a couple of minor variations to the old Bleichenbacher attack on the RSA encryption protocol. First discovered in 1998 and named after Swiss cryptographer Daniel Bleichenbacher, the Bleichenbacher attack is a padding oracle attack on RSA-based PKCS#1 v1.5 encryption scheme used in SSLv2. Leveraging an adaptive chosen-ciphertext attack which occurred due to error messages by SSL servers for errors in the PKCS #1 1.5 padding, Bleichenbacher attack allows attackers to determine whether a decrypted message is correctly padded. ...

Attack surfaces are growing faster than security teams can keep up. To stay ahead, you need to know what's exposed and where attackers are most likely to strike. With cloud migration dramatically increasing the number of internal and external targets, prioritizing threats and managing your attack surface from an attacker's perspective has never been more important. Let's look at why it's growing, and how to monitor and manage it properly with tools like  Intruder . What is your attack surface? First, it's important to understand that your attack surface is the sum of your digital assets that are 'exposed' – whether the digital assets are secure or vulnerable, known or unknown, in active use or not. This attack surface changes continuously over time, and includes digital assets that are on-premises, in the cloud, in subsidiary networks, and in third-party environments. In short, it's anything that a hacker can attack.  What is attack surface managemen...

The term " attack surface management " (ASM) went from unknown to ubiquitous in the cybersecurity space over the past few years. Gartner and Forrester have both highlighted the  importance of ASM  recently, multiple solution providers have emerged in the space, and investment and acquisition activity have seen an uptick. Many concepts come and go in cybersecurity, but attack surface management promises to have staying power. As it evolves into a critical component of threat and exposure management strategies, it’s worth examining why attack surface management has grown to become a key category, and why it will continue to be a necessity for organizations worldwide. What is Attack Surface Management?  Attack surfaces are rapidly expanding. The attack surface includes any IT asset connected to the internet – applications, IoT devices, Kubernetes clusters, cloud platforms – that threat actors could infiltrate and exploit to perpetuate an attack. A company’s attack s...

Till Now the Internet was encountering the traditional Distributed Denial of Service (DDoS) attacks , where a large number of compromised systems use to flood servers with tremendous amount of bandwidth; but in past few months we have noticed massive change in the techniques of DDoS attack. Hackers are using creative, but evil DDoS techniques such as NTP and DNS Amplification DDoS attacks. Last month we have seen that how cybercriminals abused a vulnerability in one of the biggest Chinese video hosting website Sohu.com to convert their millions of visitors to participate into the Layer 7 (Application Layer) DDoS attack with 20 Million requests. According to the new report released by a US based security solutions provider Incapsula , another interesting DDoS attack activities have been noticed by the researchers in which an attacker abused two major anti-DDoS Service providers to perform massive DDoS attack on other websites. Its really EPIC that the services who should...

Minecraft, with over 500 million registered users and 166 million monthly players, faces significant risks from distributed denial-of-service (DDoS) attacks, threatening server functionality, player experience, and the game’s reputation. Despite the prevalence of DDoS attacks on the game, the majority of incidents go unreported, leaving a gap in awareness and protection. This article explains what happens to a Minecraft server during a DDoS attack and how to protect against such attacks. For an in-depth version of the article,  check out this white paper . When Creepers Breach: What Happens When an Attack Is Successful When a Minecraft server is hit with a DDoS attack, players may have problems with logging in to servers, loading worlds, navigating biomes, using tools, and chatting. They can also experience general lags, disconnections, timeouts, or server crashes. These in-game disruptions can ruin the gaming experience for players while causing financial and reputational losse...

Earlier last year, security researchers from Google's Project Zero outlined a way to hijack the computers running Linux by abusing a design flaw in the memory and gaining higher kernel privileges on the system. Now, the same previously found designing weakness has been exploited to gain unfettered "root" access to millions of Android smartphones, allowing potentially anyone to take control of affected devices. Researchers in the VUSec Lab at Vrije Universiteit Amsterdam have discovered a vulnerability that targets a device's dynamic random access memory (DRAM) using an attack called Rowhammer . Although we are already aware of the Rowhammer attack , this is the very first time when researchers have successfully used this attack to target mobile devices. What is DRAM Rowhammer Attack? The Rowhammer attack against mobile devices is equally dangerous because it potentially puts all critical data on millions of Android phones at risk, at least until a secu...

Ukraine's biggest telecom operator Kyivstar has  become  the victim of a " powerful hacker attack ,” disrupting customer access to mobile and internet services. "The cyberattack on Ukraine's #Kyivstar telecoms operator has impacted all regions of the country with high impact to the capital, metrics show, with knock-on impacts reported to air raid alert network and banking sector as work continues to restore connectivity," NetBlocks  said  in a series of posts on X (formerly Twitter). Kyivstar, which is owned by Dutch-domiciled multinational telecommunication services company VEON,  serves  nearly 25 million mobile subscribers and more than 1 million home internet customers. The company said the attack was "a result of" the war with Russia and that it has notified law enforcement and special state services. While Kyivstar is working to restore the services, the internet watchdog noted that the telco is largely offline. That said, Kyivstar has yet ...

Yes, you only need a single laptop with a decent internet connection, rather a massive botnet, to launch overwhelming denial of service (DoS) attacks in order to bring down major Internet servers and modern-day firewalls. Researchers at TDC Security Operations Center have discovered a new attack technique that lone attackers with limited resources (in this case, a laptop and at least 15Mbps of bandwidth) can use to knock large servers offline. Dubbed a BlackNurse attack or the low-rate " Ping of Death " attack, the technique can be used to launch several low-volume DoS attacks by sending specially formed Internet Control Message Protocol (ICMP) packets, or 'pings' that overwhelm the processors on server protected by firewalls from Cisco, Palo Alto Networks, among others. ICMP is a protocol used by routers and other networking devices to send and receive error messages. According to a technical report [ PDF ] published this week, the BlackNurse attack is mo...

Here are three of the worst breaches, attacker tactics and techniques of 2022, and the security controls that can provide effective, enterprise security protection for them. #1: 2 RaaS Attacks in 13 Months Ransomware as a service is a type of attack in which the ransomware software and infrastructure are leased out to the attackers. These ransomware services can be purchased on the dark web from other threat actors and ransomware gangs. Common purchasing plans include buying the entire tool, using the existing infrastructure while paying per infection, or letting other attackers perform the service while sharing revenue with them. In this attack, the threat actor consists of one of the most prevalent ransomware groups, specializing in access via third parties, while the targeted company is a medium-sized retailer with dozens of sites in the United States. The threat actors used ransomware as a service to breach the victim's network. They were able to exploit third-party creden...

Attack surface management (ASM) and vulnerability management (VM) are often confused, and while they overlap, they’re not the same. The main difference between attack surface management and vulnerability management is in their scope: vulnerability management checks a list of known assets, while attack surface management assumes you have unknown assets and so begins with discovery. Let’s look at both in more detail. What is vulnerability management? Vulnerability management is, at the simplest level, the use of automated tools to identify, prioritize and report on security issues and vulnerabilities in your digital infrastructure. Vulnerability management uses automated scanners to run regular, scheduled scans on assets within a known IP range to detect established and new vulnerabilities, so you can apply patches, remove vulnerabilities or mitigate any potential risks. These vulnerabilities tend to use a risk score or scale – such as CVSS – and risk calculations. Vulnerability sca...
