Unpatched Microsoft Word DDE Exploit Being Used In Widespread Malware Attacks

Unpatched Microsoft Word DDE Exploit Being Used In Widespread Malware Attacks

October 20, 2017Swati Khandelwal
A newly discovered unpatched attacking method that exploits a built-in feature of Microsoft Office is currently being used in various widespread malware attack campaigns. Last week we reported how hackers could leveraging an old Microsoft Office feature called Dynamic Data Exchange (DDE), to perform malicious code execution on the targeted device without requiring Macros enabled or memory corruption. DDE protocol is one of the several methods that Microsoft uses to allow two running applications to share the same data. The protocol is being used by thousands of apps, including MS Excel, MS Word, Quattro Pro, and Visual Basic for one-time data transfers and for continuous exchanges for sending updates to one another. The DDE exploitation technique displays no "security" warnings to victims, except asking them if they want to execute the application specified in the command—although this popup alert could also be eliminated "with proper syntax modification.&quo
Simple Exploit Allows Attackers to Modify Email Content — Even After It's Sent!

Simple Exploit Allows Attackers to Modify Email Content — Even After It's Sent!

August 23, 2017Unknown
Security researchers are warning of a new, easy-to-exploit email trick that could allow an attacker to turn a seemingly benign email into a malicious one after it has already been delivered to your email inbox. Dubbed Ropemaker (stands for Remotely Originated Post-delivery Email Manipulation Attacks Keeping Email Risky), the trick was uncovered by Francisco Ribeiro, the researcher at email and cloud security firm Mimecast. A successful exploitation of the Ropemaker attack could allow an attacker to remotely modify the content of an email sent by the attacker itself, for example swapping a URL with the malicious one. This can be done even after the email has already been delivered to the recipient and made it through all the necessary spam and security filters, without requiring direct access to the recipient's computer or email application, exposing hundreds of millions of desktop email client users to malicious attacks. Ropemaker abuses Cascading Style Sheets (CSS) and Hyp

7-Year-Old Samba Flaw Lets Hackers Access Thousands of Linux PCs Remotely

May 25, 2017Swati Khandelwal
A 7-year-old critical remote code execution vulnerability has been discovered in Samba networking software that could allow a remote attacker to take control of an affected Linux and Unix machines. Samba is open-source software (re-implementation of SMB networking protocol) that runs on the majority of operating systems available today, including Windows, Linux, UNIX, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to share network shared folders, files, and printers with Windows operating system. The newly discovered remote code execution vulnerability ( CVE-2017-7494 ) affects all versions newer than Samba 3.5.0 that was released on March 1, 2010. "All versions of Samba from 3.5.0 onwards are vulnerable to a remote code execution vulnerability, allowing a malicious client to upload a shared library to a writable share, and then cause the server to load and execute it," Samba wrote in an advisory published Wed

18-Byte ImageMagick Hack Could Have Leaked Images From Yahoo Mail Server

May 23, 2017Swati Khandelwal
After the discovery of a critical vulnerability that could have allowed hackers to view private Yahoo Mail images, Yahoo retired the image-processing library ImageMagick. ImageMagick is an open-source image processing library that lets users resize, scale, crop, watermarking and tweak images. The tool is supported by PHP, Python, Ruby, Perl, C++, and many other programming languages. This popular image-processing library made headline last year with the discovery of the then-zero-day vulnerability, dubbed ImageTragick , which allowed hackers to execute malicious code on a Web server by uploading a maliciously-crafted image. Now, just last week, security researcher Chris Evans demonstrated an 18-byte exploit to the public that could be used to cause Yahoo servers to leak other users' private Yahoo! Mail image attachments. 'Yahoobleed' Bug Leaks Images From Server Memory The exploit abuses a security vulnerability in the ImageMagick library, which Evans dubbed

If you have visited any popular mainstream website over the past two months, your computer may have been infected — Thanks to a new exploit kit discovered by security researchers. Researchers from antivirus provider ESET released a report on Tuesday stating that they have discovered an exploit kit, dubbed Stegano , hiding malicious code in the pixels of banner advertisements that are currently in rotation on several high profile news websites. Stegano originally dates back to 2014, but since early October this year, cyber crooks had managed to get the malicious ads displayed on a variety of unnamed reputable news websites, each with Millions of daily visitors. Stegano derived from the word Steganography , which is a technique of hiding messages and content inside a digital graphic image, making the content impossible to spot with the naked eye. In this particular malvertising campaign, operators hide malicious code inside transparent PNG image's Alpha Channel, which def

Last week, a group calling itself " The Shadow Brokers " published what it said was a set of NSA "cyber weapons," including some working exploits for the Internet's most crucial network infrastructure, apparently stolen from the agency's Equation Group in 2013. Well, talking about the authenticity of those exploits, The Intercept published Friday a new set of documents from the Edward Snowden archive, which confirms that the files leaked by the Shadow Brokers contain authentic NSA software and hacking tools used to secretly infect computers worldwide. As I previously mentioned , the leaked documents revealed how the NSA was systematically spying on customers of big technology companies like Cisco, Fortinet, and Juniper for at least a decade. Hacking tools from The Shadow Brokers leak named ExtraBacon, EpicBanana, and JetPlow, contain exploits that can compromise Cisco firewall products including devices from the Adaptive Security Appliance (ASA) li
Mac OS X Zero-Day Exploit Can Bypass Apple's Latest Protection Feature

Mac OS X Zero-Day Exploit Can Bypass Apple's Latest Protection Feature

March 25, 2016Swati Khandelwal
A critical zero-day vulnerability has been discovered in all versions of Apple's OS X operating system that allows hackers to exploit the company's newest protection feature and steal sensitive data from affected devices. With the release of OS X El Capitan, Apple introduced a security protection feature to the OS X kernel called System Integrity Protection ( SIP ). The feature is designed to prevent potentially malicious or bad software from modifying protected files and folders on your Mac. The purpose of SIP is to restrict the root account of OS X devices and limit the actions a root user can perform on protected parts of the system in an effort to reduce the chance of malicious code hijacking a device or performing privilege escalation. However, SentinelOne security researcher Pedro Vilaça has uncovered a critical vulnerability in both OS X and iOS that allows for local privilege escalation as well as bypasses SIP without kernel exploit, impacting all versions

You should be very careful while visiting websites on the Internet because you could be hit by a new upgrade to the World's worst Exploit Kit – Angler , which lets hackers develop and conduct their own drive-by attacks on visitors' computers with relative ease. Many poorly-secured websites are targeting Windows users with a new "Cocktail" of malware that steals users' passwords before locking them out from their machines for ransom. Yes, stealing Windows users' passwords before encrypting their data and locking their PCs for ransom makes this upgrade to the Angler Exploit Kit nastier. Here's How the New Threat Works: Once the Angler exploit kit finds a vulnerable application, such as Adobe Flash, in visitor's computer, the kit delivers its malicious payloads, according to a blog post published by Heimdal Security. The First Payload infects the victim's PC with a widely used data thief exploit known as Pony that systematic

Hackers have found a new way to hack your Android smartphone and remotely gain total control of it, even if your device is running the most up-to-date version of the Android operating system. Security researcher Guang Gong recently discovered a critical zero-day exploit in the latest version of Chrome for Android that allows an attacker to gain full administrative access to the victim's phone and works on every version of Android OS. The exploit leverages a vulnerability in JavaScript v8 engine , which comes pre-installed on almost all (Millions) modern and updated Android phones. All the attacker needs to do is tricking a victim to visit a website that contains malicious exploit code from Chrome browser. Once the victim accessed the site, the vulnerability in Chrome is exploited to install any malware application without user interaction, allowing hackers to gain remotely full control of the victim's phone.

Really a bad weekend for Internet users. Three previously unknown critical zero-day vulnerabilities were revealed in Adobe's Flash Player over the weekend, thanks to Hacking team data Breach in which 400GB of internal data were leaked over the Internet. Now, a new zero-day vulnerability has been reported in Oracle's Java that is reportedly being exploited in the wild by hackers to target government armed forces. Cybercriminals are actively exploiting the Java-based zero-day flaw in an attempt to target U.S. defense agencies and members of NATO, Trend Micro security researchers warned in a blog post published Sunday. According to researchers, the vulnerability affects only the latest version of Java, version 1.8.0.45. Though the older Java versions, Java 1.6 and 1.7 are not at all affected by this zero-day exploit. So far, there isn't many details disclosed about the Java zero-day bug, considering a patch is yet to be released by Oracle. Although hackers are exploi

The Recent Cyber Attack that exposed 400GB of corporate data belonging to surveillance software firm Hacking Team has revealed that the spyware company have already discovered an exploit for an unpatched zero-day vulnerability in Flash Player. Security researchers at Trend Micro claim that the leaked data stolen from Hacking Team , an Italian company that sells surveillance software to government agencies, contains a number of unpatched and unreported Adobe flaws. Hacking Team has Unpatched Flash Bug  While analyzing the leaked data dump, researchers discovered at least three software exploits – two for Adobe Flash Player and one for Microsoft's Windows kernel. Out of two, one of the Flash Player vulnerabilities, known as Use-after-free vulnerability with CVE-2015-0349 , has already been patched. However, the Hacking Team described the other Flash Player exploit, which is a zero-day exploit with no CVE number yet, as "the most beautiful Flash bug for
Hacker Finds a Simple Way to Bypass Google Password Alert

Hacker Finds a Simple Way to Bypass Google Password Alert

May 02, 2015Mohit Kumar
Less than 24 hours after Google launched the new Phishing alert extension Password Alert , a security researcher was able to bypass the feature using deadly simple exploits. On Wednesday, the search engine giant launched a new Password Alert Chrome extension to alert its users whenever they accidentally enter their Google password on a carefully crafted phishing website that aimed at hijacking users' account. However, security expert Paul Moore easily circumvented the technology using just seven lines of simple JavaScript code that kills phishing alerts as soon as they started to appear, defeating Google's new Password Alert extension. Google shortly fixed the issue and released a new update to Password Alert extension that blocked the Moore's exploit. However, Moore discovered another way to block the new version of Password Alert, as well. The first proof of concept exploit by Moore relied on a JavaScript that looks for instances of warning screen every five mil

More Hacking Groups Found Exploiting SMB Flaw Weeks Before WannaCry

May 19, 2017Mohit Kumar
Since the Shadow Brokers released the zero-day software vulnerabilities and hacking tools – allegedly belonged to the NSA's elite hacking team Equation Group – several hacking groups and individual hackers have started using them in their own way. The April's data dump was believed to be the most damaging release by the Shadow Brokers till the date, as it publicly leaked lots of Windows hacking tools , including dangerous Windows SMB exploit. After the outbreak of WannaCry last week, security researchers have identified multiple different campaigns exploiting Windows SMB vulnerability (CVE-2017-0143), called Eternalblue , which has already compromised hundreds of thousands of computers worldwide. I have been even confirmed by multiple sources in hacking and intelligence community that there are lots of groups and individuals who are actively exploiting Eternalblue for different motives. Moreover, the Eternalblue SMB exploit ( MS17-010 ) has now been ported to  Met

A New vBulletin 0-Day RCE Vulnerability and Exploit Disclosed Publicly

August 11, 2020Swati Khandelwal
A security researcher earlier today publicly revealed details and proof-of-concept exploit code for an unpatched, critical zero-day remote code execution vulnerability affecting the widely used internet forum software vBulletin that's already under active exploitation in the wild. vBulletin is a widely used proprietary Internet forum software package based on PHP and MySQL database server that powers over 100,000 websites on the Internet, including Fortune 500 and Alexa Top 1 million companies websites and forums. In September last year, a separate anonymous security researcher publicly disclosed a then-zero-day RCE vulnerability in vBulletin , identified as CVE-2019-16759 , and received a critical severity rating of 9.8, allowing attackers to execute malicious commands on the remote server without requiring any authentication to log into the forum. A day after the disclosure of CVE-2019-16759, the vBulletin team released security patches that resolved the issue, but it t

Latest Microsoft Update Patches New Windows 0-Day Under Active Attack

December 10, 2019Swati Khandelwal
With its latest and last Patch Tuesday for 2019, Microsoft is warning billions of its users of a new Windows zero-day vulnerability that attackers are actively exploiting in the wild in combination with a Chrome exploit to take remote control over vulnerable computers. Microsoft's December security updates include patches for a total of 36 vulnerabilities, where 7 are critical, 27 important, 1 moderate, and one is low in severity—brief information on which you can find later in this article. Tracked as CVE-2019-1458 and rated as Important, the newly patched zero-day Win32k privilege escalation vulnerability, reported by Kaspersky, was used in Operation WizardOpium attacks to gain higher privileges on targeted systems by escaping the Chrome sandbox. Although Google addressed the flaw in Chrome 78.0.3904.87 with the release of an emergency update last month after Kaspersky disclosed it to the tech giant, hackers are still targeting users who are using vulnerable versions of th
First Cyber Attack 'Mass Exploiting' BlueKeep RDP Flaw Spotted in the Wild

First Cyber Attack 'Mass Exploiting' BlueKeep RDP Flaw Spotted in the Wild

November 03, 2019Mohit Kumar
Cybersecurity researchers have spotted a new cyberattack that is believed to be the very first but an amateur attempt to weaponize the infamous BlueKeep RDP vulnerability in the wild to mass compromise vulnerable systems for cryptocurrency mining. In May this year, Microsoft released a patch for a highly-critical remote code execution flaw, dubbed  BlueKeep , in its Windows Remote Desktop Services that could be exploited remotely to take full control over vulnerable systems just by sending specially crafted requests over RDP. BlueKeep, tracked as CVE-2019-0708 , is a wormable vulnerability because it can be weaponized by potential malware to propagate itself from one vulnerable computer to another automatically without requiring victims' interaction. BlueKeep has been considered to be such a serious threat that since its discovery, Microsoft and even government agencies [ NSA and GCHQ ] had continuously been encouraging Windows users and admins to apply security patches bef
