You have always been warned not to share remote access to your computer with untrusted people for any reason—it's a basic cybersecurity advice, and common sense, right? But what if, I say you should not even trust anyone who invites or offer you full remote access to their computers. A critical vulnerability has been discovered in Microsoft's Windows Remote Assistanc e (Quick Assist) feature that affects all versions of Windows to date, including Windows 10, 8.1, RT 8.1, and 7, and allows remote attackers to steal sensitive files on the targeted machine. Windows Remote Assistance is a built-in tool that allows someone you trust to take over your PC (or you to take remote control of others) so they can help you fix a problem from anywhere around the world. The feature relies on the Remote Desktop Protocol (RDP) to establish a secure connection with the person in need. However, Nabeel Ahmed of Trend Micro Zero Day Initiative discovered and reported an information di

The notorious Lazarus Group actors exploited a recently patched privilege escalation flaw in the Windows Kernel as a zero-day to obtain kernel-level access and disable security software on compromised hosts. The vulnerability in question is  CVE-2024-21338  (CVSS score: 7.8), which can permit an attacker to gain SYSTEM privileges. It was resolved by Microsoft earlier this month as part of  Patch Tuesday updates . "To exploit this vulnerability, an attacker would first have to log on to the system," Microsoft  said . "An attacker could then run a specially crafted application that could exploit the vulnerability and take control of an affected system." While there were no indications of active exploitation of CVE-2024-21338 at the time of the release of the updates, Redmond on Wednesday revised its "Exploitability assessment" for the flaw to "Exploitation Detected."  It's currently not clear when the attacks took place, but the vulnerability

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

Ransomware is an emerging threat in the evolution of cybercriminals techniques to part you from your money. Typically, the malicious software either lock victim's computer system or encrypt the documents and files on it, in order to extort money from the victims. Though earlier we saw the samples of Ransomware tended to be simple with dogged determinations to extort money from victims. But with the exponential rise in the samples of Ransomware malwares, the recent ones are more subtle in design, including Cryptolocker , Icepole , PrisonLocker , CryptoDefense and its variants. Now, the ransomware dubbed as Crytowall , a latest variant of the infamous ransomware Cryptolocker is targeting users by forcing them to download the malicious software by through advertising on the high profile domains belonging to Disney, Facebook, The Guardian newspaper and others. Cryptolocker is designed by the same malware developer who created the sophisticated CryptoDefense ( Trojan.Crypt

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 to e

Microsoft is urging customers to keep their Exchange servers updated as well as take steps to bolster the environment, such as enabling  Windows Extended Protection  and configuring  certificate-based signing  of PowerShell serialization payloads. "Attackers looking to exploit unpatched Exchange servers are not going to go away," the tech giant's Exchange Team  said  in a post. "There are too many aspects of unpatched on-premises Exchange environments that are valuable to bad actors looking to exfiltrate data or commit other malicious acts." Microsoft also emphasized mitigations issued by the company are only a stopgap solution and that they can "become insufficient to protect against all variations of an attack," necessitating that users install necessary security updates to secure the servers. Exchange Server has been proven to be a lucrative attack vector in recent years, what with a number of security flaws in the software weaponized as zero-d

PSB.org was hacked with 0day exploit for MoveableType ! Yesterday  Public Broadcasting Service (PBS) was Hacked by Lulzsec, Users data & Database Leaked.  Lulzsec hackers today expose that, how exactly they hack all these database, site and Server. They Use 0day exploit for MoveableType, Using the vulnerability they uploaded php shell on ftp and Then root the server using localroot exploit for kernel 27 2.4.21-37.ELsmp 2005 i686 . Kevin Mitnick (World top hacker) says : " Yeah, they claim it's a bug in mt4... but I doubt they would reveal the vector until much later. " The /etc/passwd file of server is as shown below: They use  Havij 1.14 Pro - Sql injection tool, just to make hack faster and extract whole database. On Tuesday,  LulzSec tweeted on their twitter profile &  included messages directed to both Manning and Wikileaks." @WikiLeaks We hope our hacking gave Bradley Manning a smile. That man deserves something nice ,"  a

A zero-day software vulnerability discovered deep in the firmware of many Apple computers could allows an attacker to modify the system's BIOS and install a rootkit , potentially gaining complete control of the victim's Mac. The critical vulnerability, discovered by well-known OS X security researcher Pedro Vilaca, affects Mac computers shipped before mid-2014 that are allowed to go into sleep mode. While studying Mac security, Vilaca found that it's possible to tamper with Apple computer's UEFI (unified extensible firmware interface) code. UEFI is a low-level firmware designed to improve upon computer's BIOS, which links a computer's hardware and operating system at startup and is typically not accessible to users. But… Vilaca found that the machine's UEFI code can be unlocked after a computer is put to sleep and then brought back up. " And you ask, what the hell does this mean? " Vilaca wrote in a blog post published Friday. " It means th

The infamous hacking collective Shadow Brokers – the one who leaked the Windows SMB exploit in public that led to last weekend's WannaCrypt menace – are back, this time, to cause more damage. In typically broken English, the Shadow Brokers published a fresh statement (with full of frustration) a few hours ago, promising to release more zero-day bugs and exploits for various desktop and mobile platforms starting from June 2017. However, this time the Shadow Brokers leaks will not be available for everybody, as the hacking collective said: "TheShadowBrokers is launching new monthly subscription model. Is being like [the] wine of month club. Each month peoples can be paying membership fee, then getting members only data dump each month." To some extent, this is good news, but it is terrible news too. Good because now all these upcoming alleged unpatched vulnerabilities will be patched after being disclosed and terrible because the group will sell new zero-day e

A set of 38 security vulnerabilities has been uncovered in wireless industrial internet of things (IIoT) devices from four different vendors that could pose a significant attack surface for threat actors looking to exploit operational technology (OT) environments. "Threat actors can exploit vulnerabilities in Wireless IIoT devices to gain initial access to internal OT networks," Israeli industrial cybersecurity company Otorio  said . "They can use these vulnerabilities to bypass security layers and infiltrate target networks, putting critical infrastructure at risk or interrupting manufacturing." The flaws, in a nutshell, offer a remote entry point for attack, enabling unauthenticated adversaries to gain a foothold and subsequently use it as leverage to spread to other hosts, thereby causing serious damage. Some of the identified shortcomings could be chained to give an external actor direct access to thousands of internal OT networks over the internet, security

If the connectivity and security of your organization rely on Cisco RV320 or RV325 Dual Gigabit WAN VPN routers, then you need to immediately install the latest firmware update released by the vendor last week. Cyber attackers have actively been exploiting two newly patched high-severity router vulnerabilities in the wild after a security researcher released their proof-of-concept exploit code on the Internet last weekend. The vulnerabilities in question are a command injection flaw (assigned CVE-2019-1652) and an information disclosure flaw (assigned CVE-2019-1653), a combination of which could allow a remote attacker to take full control of an affected Cisco router. The first issue exists in RV320 and RV325 dual gigabit WAN VPN routers running firmware versions 1.4.2.15 through 1.4.2.19, and the second affects firmware versions 1.4.2.15 and 1.4.2.17, according to the Cisco's advisory . Both the vulnerabilities, discovered and responsibly reported to the company by German s

In its April slate of patches, Microsoft rolled out fixes for a total of  114 security flaws , including an actively exploited zero-day and four remote code execution bugs in Exchange Server. Of the  114 flaws , 19 are rated as Critical, 88 are rated Important, and one is rated Moderate in severity. Chief among them is  CVE-2021-28310 , a privilege escalation vulnerability in Win32k that's said to be under active exploitation, allowing attackers to elevate privileges by running malicious code on a target system.  Cybersecurity firm Kaspersky, which discovered and reported the flaw to Microsoft in February, linked the zero-day exploit to a threat actor named Bitter APT, which was found exploiting a similar flaw ( CVE-2021-1732 ) in attacks late last year. "It is an escalation of privilege (EoP) exploit that is likely used together with other browser exploits to escape sandboxes or get system privileges for further access," Kaspersky researcher Boris Larin  said .

Most of the time, we have reported about WordPress vulnerabilities involving vulnerable plugins, but this time a Finnish security researcher has discovered a critical zero-day vulnerability in the core engine of the WordPress content management system. Yes, you heard it right. The WordPress CMS used by Millions of website is vulnerable to a zero-day flaw that could allow hackers to remote code execution on the Web server in order to take full control of it. The vulnerability, found by Jouko Pynnönen of Finland-based security firm Klikki Oy, is a Cross-Site Scripting (XSS) flaw buried deep into the WordPress' comments system. The vulnerability affects the WordPress versions 3.9.3, 4.1.1, 4.1.2, and the latest WordPress version 4.2. Pynnönen disclosed the details of the zero-day flaw, along with a video and a proof-of-concept code for an exploit of the bug, on his blog post on Sunday before the WordPress team could manage to release a patch. Why the researcher m

Microsoft on Tuesday released security update (KB 4010250) to patch flaws in Adobe Flash Player for its customers using Internet Explorer on Windows 8.1 and later, as well as Edge for Windows 10, but two already disclosed flaws remain unpatched. Just last week, Microsoft announced that its February patches would be delayed until March due to a last minute issue, a move that led to Google publishing details of an unpatched Windows bug . However, the software giant emailed a handful of big business to alert them to the incoming patches on Monday, advising them to update their systems as soon as possible. The security patches are now available to all Windows customers over Windows Update, and " No other security updates are scheduled for release until the next scheduled monthly update release on March 14, 2017 ," Microsoft says. Bulletin MS17-005 for Adobe Flash Player addresses remote code execution (RCE) vulnerabilities for some currently supported Windows systems.

Cybersecurity researchers today uncovered a new critical vulnerability affecting the Server Message Block (SMB) protocol that could allow attackers to leak kernel memory remotely, and when combined with a previously disclosed "wormable" bug, the flaw can be exploited to achieve remote code execution attacks. Dubbed " SMBleed " ( CVE-2020-1206 ) by cybersecurity firm ZecOps, the flaw resides in SMB's decompression function — the same function as with SMBGhost or EternalDarkness bug ( CVE-2020-0796 ), which came to light three months ago, potentially opening vulnerable Windows systems to malware attacks that can propagate across networks. The newly discovered vulnerability impacts Windows 10 versions 1903 and 1909, for which Microsoft today released security patches as part of its monthly Patch Tuesday updates for June . The development comes as the US Cybersecurity and Infrastructure Security Agency (CISA) issued an advisory last week warning Windows 10

The infamous eGobbler hacking group that surfaced online earlier this year with massive malvertising campaigns has now been caught running a new campaign exploiting two browser vulnerabilities to show intrusive pop-up ads and forcefully redirect users to malicious websites. To be noted, hackers haven't found any way to run ads for free; instead, the modus operandi of eGobbler attackers involves high budgets to display billions of ad impressions on high profile websites through legit ad networks. But rather than relying on visitors' willful interaction with advertisements online, eGobbler uses browser (Chrome and Safari) exploits to achieve maximum click rate and successfully hijack as many users' sessions as possible. In its previous malvertising campaign, eGobbler group was exploiting a then-zero-day vulnerability (CVE-2019-5840) in Chrome for iOS back in April , which allowed them to successfully bypass browser's built-in pop-up blocker on iOS devices and hij

Romanian cybersecurity technology company Bitdefender on Monday revealed that attempts are being made to target Windows machines with a novel ransomware family called  Khonsari  as well as a remote access Trojan named  Orcus  by exploiting the recently disclosed critical Log4j vulnerability . The attack leverages the remote code execution (RCE) flaw to download an additional payload, a .NET binary, from a remote server that encrypts all the files with the extension ".khonsari" and displays a ransom note that urges the victims to make a Bitcoin payment in exchange for recovering access to the files. Tracked as CVE-2021-44228 , the RCE vulnerability is also known by the monikers "Log4Shell" or "Logjam" and impacts versions 2.0-beta9 to 2.14.1 of the software library. In simple terms, the bug could force an affected system to download malicious software, giving the attackers a digital beachhead on servers located within corporate networks. Log4j is an op
