Log4Shell ,  ProxyShell ,  ProxyLogon ,  ZeroLogon , and flaws in  Zoho ManageEngine AD SelfService Plus ,  Atlassian Confluence , and  VMware vSphere Client  emerged as some of the top exploited security vulnerabilities in 2021. That's according to a " Top Routinely Exploited Vulnerabilities " report released by cybersecurity authorities from the Five Eyes nations Australia, Canada, New Zealand, the U.K., and the U.S. Other frequently weaponized flaws included a remote code execution bug in Microsoft Exchange Server ( CVE-2020-0688 ), an arbitrary file read vulnerability in Pulse Secure Pulse Connect Secure ( CVE-2019-11510 ), and a path traversal defect in Fortinet FortiOS and FortiProxy ( CVE-2018-13379 ). Nine of the top 15 routinely exploited flaws were remote code execution vulnerabilities, followed by two privilege escalation weaknesses, and one each of security feature bypass, arbitrary code execution, arbitrary file read, and path traversal flaws. "G

As many as 55 zero-day vulnerabilities were exploited in the wild in 2022, with most of the flaws discovered in software from Microsoft, Google, and Apple. While this figure represents a decrease from the year before, when a staggering 81 zero-days were weaponized, it still represents a significant uptick in recent years of threat actors leveraging unknown security flaws to their advantage. The  findings  come from threat intelligence firm Mandiant, which noted that desktop operating systems (19), web browsers (11), IT and network management products (10), and mobile operating systems (six) accounted for the most exploited product types. Of the 55 zero-day bugs, 13 are estimated to have been abused by cyber espionage groups, with four others exploited by financially motivated threat actors for ransomware-related operations. Commercial spyware vendors were linked to the exploitation of three zero-days. Among state-sponsored groups, those attributed to China have emerged as the most

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

Microsoft's  Patch Tuesday update  for the month of March has been made officially available with 71 fixes spanning across its software products such as Windows, Office, Exchange, and Defender, among others. Of the total 71 patches, three are rated Critical and 68 are rated Important in severity. While none of the vulnerabilities are listed as actively exploited, three of them are publicly known at the time of release. It's worth pointing out that Microsoft separately  addressed 21 flaws  in the Chromium-based Microsoft Edge browser earlier this month. All the three critical vulnerabilities remediated this month are remote code execution flaws impacting HEVC Video Extensions ( CVE-2022-22006 ), Microsoft Exchange Server ( CVE-2022-23277 ), and VP9 Video Extensions ( CVE-2022-24501 ). The Microsoft Exchange Server vulnerability, which was reported by researcher Markus Wulftange, is also noteworthy for the fact that it requires the attacker to be authenticated to be able to

NSS Labs issued the report titled " The Known Unknowns " to explain the dynamics behind the market of zero-day exploits. Last week I discussed about the necessity to define a model for " cyber conflict " to qualify the principal issues related to the use of cyber tools and cyber weapons in an Information Warfare context, today I decided to give more info to the readers on cyber arsenals of governments. Governments consider the use of cyber weapons as a coadiuvant to conventional weapons, these malicious application could be used for sabotage or for cyber espionage, they could be used to hit a specifically designed software (e.g. SCADA within a critical infrastructure ) or they could be used for large scale operations infecting thousand of machines exploiting zero-day in common application ( e.g. Java platform, Adobe software ). The zero-day flaw are the most important component for the design of an efficient cyber weapon, governments have recently created dedic

The Department of Homeland Security and CISA ICS-CERT today issued a critical security advisory warning about over a dozen newly discovered vulnerabilities affecting billions of Internet-connected devices manufactured by many vendors across the globe. Dubbed " Ripple20 ," the set of 19 vulnerabilities resides in a low-level TCP/IP software library developed by Treck, which, if weaponized, could let remote attackers gain complete control over targeted devices—without requiring any user interaction. According to Israeli cybersecurity company JSOF—who discovered these flaws—the affected devices are in use across various industries, ranging from home/consumer devices to medical, healthcare, data centers, enterprises, telecom, oil, gas, nuclear, transportation, and many others across critical infrastructure. "Just a few examples: data could be stolen off of a printer, an infusion pump behavior changed, or industrial control devices could be made to malfunction. An

As part of this month's Patch Tuesday, Microsoft has released security patches for a total of 55 vulnerabilities across its products, including fixes for four zero-day vulnerabilities being exploited in the wild. Just yesterday, Microsoft released an emergency out-of-band update separately to patch a remote execution bug ( CVE-2017-0290 ) in Microsoft's Antivirus Engine that comes enabled by default on Windows 7, 8.1, RT, 10 and Server 2016 operating systems. The vulnerability, reported by Google Project Zero researchers, could allow an attacker to take over your Windows PC with just an email, which you haven't even opened yet. May 2017 Patch Tuesday — Out of 55 vulnerabilities, 17 have been rated as critical and affect the company's main operating systems, along with other products like Office, Edge, Internet Explorer, and the malware protection engine used in most of the Microsoft's anti-malware products. Sysadmins all over the world should prioriti

Cybersecurity today matters so much because of everyone's dependence on technology, from collaboration, communication and collecting data to e-commerce and entertainment. Every organisation that needs to deliver services to their customers and employees must protect their IT 'network' - all the apps and connected devices from laptops and desktops to servers and smartphones. While traditionally, these would all live on one "corporate network," - networks today are often just made up of the devices themselves, and how they're connected: across the internet, sometimes via VPNs, to the homes and cafes people work from, to the cloud and data centres where services live. So what threats does this modern network face? Let's look at them in more detail. #1 Misconfiguration According to recent research by  Verizon , misconfiguration errors and misuse now make up 14% of breaches. Misconfiguration errors occur when configuring a system or application so that it&

As the business environment becomes increasingly connected, organizations' attack surfaces continue to expand, making it challenging to map and secure both known and unknown assets. In particular, unknown assets present security challenges related to shadow IT, misconfigurations, ineffective scan coverage, among others. Given attack surface sprawl and evolving threats, many organizations are embracing  attack surface management (ASM)  tools to discover and address critical exposures. Asset discovery is an important capability to have, and one that's helping to drive the adoption of attack surface management tools and services. That said, asset discovery is only one aspect of effective attack surface management. Making the attack surface as impenetrable as possible takes offensive security that goes far beyond the discovery phase. Why Asset Discovery Isn't Enough  Given the complexity and ever-expanding scale of the digital infrastructure at most companies, cataloging all the known

Microsoft Internet Information Services (IIS) is a web server software package designed for Windows Server. Organizations commonly use Microsoft IIS servers to host websites, files, and other content on the web. Threat actors increasingly target these Internet-facing resources as low-hanging fruit for finding and exploiting vulnerabilities that facilitate access to IT environments.  Recently, a slew of activity by the advanced persistent threat (APT) group Lazarus has focused on finding vulnerable Microsoft IIS servers and infecting them with malware or using them to distribute malicious code. This article describes the details of the malware attacks and offers actionable suggestions for protecting Microsoft IIS servers against them.  An Overview on Microsoft IIS Servers IIS was first introduced with Windows NT 3.51 as an optional package back in 1995. Since then, it has seen several iterations, improvements, and features added to align with the evolving Internet, including support

ChatGPT: Productivity tool, great for writing poems, and… a security risk?! In this article, we show how threat actors can exploit ChatGPT, but also how defenders can use it for leveling up their game. ChatGPT is the most swiftly growing consumer application to date. The extremely popular generative AI chatbot has the ability to generate human-like, coherent and contextually relevant responses. This makes it very valuable for applications like content creation, coding, education, customer support, and even personal assistance. However, ChatGPT also comes with security risks. ChatGPT can be used for data exfiltration, spreading misinformation, developing cyber attacks and writing phishing emails. On the flip side, it can help defenders who can use it for identifying vulnerabilities and learning about various defenses. In this article, we show numerous ways attackers can exploit ChatGPT and the OpenAI Playground. Just as importantly, we show ways that defenders can leverage ChatGPT t

The hacker group that exposed holes in McAfee's website knows it's breaking U.S. law, but vows to continue exposing vulnerabilities, especially on security vendor websites. The hacker group that exposed holes in McAfee's website knows it's breaking U.S. law, but vows to continue exposing vulnerabilities, especially on security vendor websites. "We do understand performing security testings without authorization is illegal under U.S. law," stated YGN Ethical Hacker Group, when contacted by Network World via e-mail. The outfit's own website describes YGN as a "small group of young but mature people" based in the country of Myanmar (Burma) who started working together about three years ago. Based on its website advertising, the group, which seeks to emphasize its goals are "ethical," appears to offer vulnerability-testing services while also working on security testing tools. In response to a question about why it's so secretive,
