Last weekend a security researcher publically disclosed a zero-day vulnerability in Windows 10, Windows 8.1 and Server editions after Microsoft failed to patch it in the past three months. The zero-day memory corruption flaw resides in the implementation of the SMB (server message block) network file sharing protocol that could allow a remote, unauthenticated attacker to crash systems with denial of service attack, which would then open them to more possible attacks. According to US-CERT, the vulnerability could also be exploited to execute arbitrary code with Windows kernel privileges on vulnerable systems, but this has not been confirmed right now by Microsoft. Without revealing the actual scope of the vulnerability and the kind of threat the exploit poses, Microsoft has just downplayed the severity of the issue, saying: "Windows is the only platform with a customer commitment to investigate reported security issues, and proactively update impacted devices as soon as

Ransomware threat has risen exponentially so much that ransomware authors have started abusing the MBR in their attacks to lock down your entire computer instead of just encrypting your important files on hard drive. Talos team at Cisco Systems has released a free, open-source tool that protects the master boot record (MBR) sector of computers from modification by bootkits, ransomware, and other malicious attacks. Master Boot Record (MBR) is the first sector (512 bytes) on your Hard drive that stores the bootloader, a piece of code that is responsible for booting the current Operating System. Technically, Bootloader is first code that gets executed after system BIOS that tells your computer what to do when it start. An advanced malware program, such as rootkit and bootkit, leverages this process to infect computers by modifying the MBR. A boot malware or bootkits has the ability to install ransomware or other malicious software into your Windows kernel, which is almost i

Identities now transcend human boundaries. Within each line of code and every API call lies a non-human identity. These entities act as programmatic access keys, enabling authentication and facilitating interactions among systems and services, which are essential for every API call, database query, or storage account access. As we depend on multi-factor authentication and passwords to safeguard human identities, a pressing question arises: How do we guarantee the security and integrity of these non-human counterparts? How do we authenticate, authorize, and regulate access for entities devoid of life but crucial for the functioning of critical systems? Let's break it down. The challenge Imagine a cloud-native application as a bustling metropolis of tiny neighborhoods known as microservices, all neatly packed into containers. These microservices function akin to diligent worker bees, each diligently performing its designated task, be it processing data, verifying credentials, or

Microsoft has released its monthly Patch Tuesday update including a total of 10 security bulletin, and you are required to apply the whole package of patches altogether, whether you like it or not. That's because the company is kicking off a controversial new all-or-nothing patch model this month by packaging all security updates into a single payload, removing your ability to pick and choose which individual patches to install. October's patch bundle includes fixes for at least 5 separate dangerous zero-day vulnerabilities in Internet Explorer, Edge, Windows and Office products that attackers were already exploiting in the wild before the patch release. The patches for these zero-day flaws are included in MS16-118, MS16-119, MS16-120, MS16-121 and MS16-126. All the zero-days are being exploited in the wild, allowing attackers to execute a remote command on victim's system. Although none of the zero-day flaws were publicly disclosed prior to Tuesday, the company wa

How much a Windows zero-day exploit that affects all versions of Windows operating system costs on the black market? It's $95,000, at least, for the one recently spotted by security researchers. Researchers from Trustwave's SpiderLabs team have uncovered a zero-day exploit on Russian underground malware forum exploit.in, affecting all versions of Microsoft Windows OS from Windows 2000 all the way up to a fully patched version of Windows 10. The zero-day exploit for the previously unknown vulnerability in " every version " of Windows is openly sold for $90,000 ( over £62,000 ). The security team originally discovered the zero-day exploit last month when the firm saw its ad on a Russian hacking forum for $95,000. However, the price has now been dropped to $90,000. The zero-day vulnerability in question claims to be a Local Privilege Escalation (LPE) bug in Windows that offers admin access to run malicious code on a victim's PC and is less dangerous th

If you are a Microsoft's Windows user, you may have encountered the infamous Blue Screen of Death (BSOD) . The Blue Screen of Death generally appears when Windows encounters any critical error due to software or hardware issues, displaying a sad face and no information other than "Your PC ran into a problem." However, now the company is apparently giving its infamous Blue Screen of Death a makeover. With the Microsoft's Anniversary Update, the company is making the Blue Screen of Death a little helpful for its users. Microsoft is adding QR code to its Blue Screen of Death (BSOD) in Windows 10 that will make it easier for users to identify potential issues with their devices. The new QR codes are featured in the Redmond's latest Windows 10 Preview, Build 14316, which will debut this summer as the Windows 10 Anniversary Update. Must Read:   Step-by-Step Tutorial to Run Ubuntu on latest Windows 10 Preview Build . Now, when your operating

Do you deal with MS Word files on the daily basis? If yes, then are you aware that even opening a simple doc file could compromise your system? It is a matter to think that the virus does not directly affect you, but it is you who let the virus carry out the attack by enabling deadly "Macros" to view the doc contents that are generally on eye-catching subjects like bank invoice. How Macros are Crippling your System? The concept of Macros dates back to 1990s. You must be familiar with this message: " Warning: This document contains macros. " A Macro is a series of commands and actions that help to automate some tasks. Microsoft Office programs support Macros written in Visual Basic for Applications (VBA), but they can also be used for malicious activities like installing malware. Hackers are cleverly using this technique on the shade of social engineering by sending the malicious Macros through doc file or spreadsheet with an eye-catching subject in t

If you receive a mail masquerading as a company's invoice and containing a Microsoft Word file, think twice before clicking on it. Doing so could cripple your system and could lead to a catastrophic destruction. Hackers are believed to be carrying out social engineering hoaxes by adopting eye-catching subjects in the spam emails and compromised websites to lure the victims into installing a deadly ransomware, dubbed " Locky ," into their systems. So if you find .locky extension files on your network shares, Congratulations! You are infected and left with just two solutions: Rebuild your PC from scratch or Pay the ransom. Locky ransomware is spreading at the rate of 4000 new infections per hour , which means approximately 100,000 new infections per day . Microsoft MACROS are Back It is hard to digest the fact that, in this 2016, even a single MS Word document could compromise your system by enabling ' Macros .' This is where the poin

Microsoft's Windows 10 , the latest version of Windows Operating System, has been creating waves since it rolled out, and reached to 110 million devices within just 2 months. If you are a long-time Windows user, you may remember a trick called, ' God Mode '. God Mode is an inbuilt, but hidden feature of Windows that provides additional customization options for the operating system. With Windows 10, all the Settings of the operating system are kept under Settings App, and categorized between System, Devices, Network & Internet, Personalization, Update & Security, Privacy and more. Enabling God Mode, also known as 'Windows Master Control Panel Shortcut ', in Windows 10 essentially unlocks a backdoor of the OS to access 260+ additional settings from a single folder. How to Enable God Mode in Windows 10? Follow the steps given below to enable the God Mode in your Windows 10: Create a new folder on your Windows desktop (New > Folder) and save it with th

If you think that the patches delivered through Windows update can not be laced with malware, think again. Security researchers have shown that Hackers could intercept Windows Update to deliver and inject malware in organizations. Security researchers from UK-based security firm ' Context ' have discovered a way to exploit insecurely configured implementations of Windows Server Update Services (WSUS) for an enterprise. What is WSUS in Windows? Windows Server Update Services (WSUS) allows an administrator to deploy the Windows software update to servers and desktops throughout the organization. These updates come from the WSUS server and not Windows server. Once the updates are with the administrator on the server, he can limit the privilege for the clients in a corporate environment to download and install these updates. As the admin is the owner of the distribution of these updates. Intercepting WSUS to Inject Malware into Corporate Networks By def

In the wake of a critical Remote Code Execution vulnerability in all supported versions of its operating system platform, Microsoft has just issued an emergency fix. Yes, it's time to patch your Windows operating system against an alarming security hole that could allow remote attackers to run malicious code on your computer, thereby taking " complete control of the affected system. " The critical flaw ( CVE-2015-2426 ), which affects all the supported versions of Windows operating system, resides in the way Windows Adobe Type Manager Library handles specially crafted Microsoft's OpenType fonts. Once exploited, the vulnerability could allow hackers to execute remotely malicious code on victims' computer if they open a specially crafted document or visit an untrusted web page that contains embedded OpenType fonts. " An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights ," Microsoft s

Security researchers have unearthed a serious security flaw in all supported versions of Windows that could let hackers steal users' credentials from computers, tablets or servers running any version of Windows operating system, including the as-yet-released Windows 10. This vulnerability in Windows was first discovered 20 Years ago : The critical bug, dubbed " Redirect to SMB ," is a variant of a vulnerability found in Windows by researcher Aaron Spangler nearly 18 years ago that caused Windows to expose a user's Windows username and password automatically. However, according to researchers at security firm Cylance who discovered the flaw, this weakness in Windows was never patched by Microsoft, as Microsoft says that this flaw is not worth focusing on, and, therefore... ...This results in a new hack that targets the SMB file sharing protocol . But, What is SMB? SMB, or Server Message Block, is a protocol that allows users to share files o

Among several vulnerabilities, Microsoft on Tuesday patched a critical vulnerability that could be exploited by hackers to bypass security measures on all versions of Windows operating systems from XP to Windows 10, just by modifying a single bit. The local privilege escalation vulnerability ( CVE-2015-0057 ) could give attackers total control of the victims' machines, explains Udi Yavo, the chief technology officer at the security firm enSilo. " A threat actor that gains access to a Windows machine can exploit this vulnerability to bypass all Windows security measures, defeating mitigation measures such as sandboxing, kernel segregation and memory randomization ," said Yavo. INTERESTING PART OF THE FLAW Yavo continued, " Interestingly, the exploit requires modifying only a single bit of the Windows operating system. " The flaw existed in the graphical user interface (GUI) component of the Win32k.sys module within the Windows Kernel which, amon

A new dangerous variant of ZeuS Banking Trojan has been identified by Comodo AV labs which is signed by stolen Digital Certificate which belongs to Microsoft Developer to avoid detection from Web browsers and anti-virus systems. Every Windows PC in the world is set to accept software " signed " with Microsoft's digital certificates of authenticity, an extremely sensitive cryptography seal. Cyber Criminals somehow managed to hack valid Microsoft digital certificate, used it to trick users and admins into trusting the file. Since the executable is digitally signed by the Microsoft developer no antivirus tool could find it as malicious. Digitally signed malware received a lot of media attention last year. Reportedly, more than 200,000 unique malware binaries were discovered in past two years signed with valid digital signatures. A Comodo User submitted a sample of the malicious software that attempts to trick user by masquerading itself as file of Intern

Last week, the Researchers at the German security company G Data Software have reported about the most complex and sophisticated rootkit  malware, Uroburos which is designed to steal data from secure facilities and has ability to take control of an infected machine, execute arbitrary commands and hide system activities. Recently, British cyber specialist BAE  has disclosed the parent Russian malware campaign dubbed as ' SNAKE ' that remained almost undetected for least eight years while penetrating highly secured systems. Uroburos rootkit was one of the components of this campaign. In a separate Investigation, Western intelligence officers have found another piece of spyware , infecting hundreds of government computers across Europe and the United States, known as ' Turla '. Researchers believed that  Turla  campaign is linked to a previously known campaign ' Red October ', a massive global cyber spying operation targeting diplomatic, military and nuclear

Cyber criminals are taking advantage of the widespread popularity of the mobile messaging app ' WhatsApp '. A malware expert at the Kaspersky Lab revealed a large-scale spamming campaign, advertising a fake PC version of the WhatsApp , to spread a banking trojan. According to the report, unaware users have received an email written in Portuguese language , it also tries to deceive the recipient with a social engineering tactic in which cyber criminals composed the malicious email informing that victims already have 11 pending friend invitations.  If users click on the " Baixar Agora " (Download Now) link in the spam email, they will be redirected to a Hightail.com URL to download the Trojan. Hightail is a cloud storage service, the malicious component deployed on it then downloads the malware via a server in Brazil. The file stored on Hightail server looks like a 64-bit installation file bundled with 2.5 megabyte MP3 file. According to Virus Total engine, onl
