Security researchers have discovered not one or two, but a total of seven security vulnerabilities in the popular open source Dnsmasq network services software, three of which could allow remote code execution on a vulnerable system and hijack it. Dnsmasq is a widely used lightweight network application tool designed to provide DNS (Domain Name System) forwarder, DHCP (Dynamic Host Configuration Protocol) server, router ads and network boot services for small networks. Dnsmasq comes pre-installed on various devices and operating systems, including Linux distributions such as Ubuntu and Debian, home routers, smartphones and Internet of Things (IoT) devices. A shodan scan for "Dnsmasq" reveals around 1.1 million instances worldwide. Recently, Google's security team reviewed Dnsmasq and discovered seven security issues, including DNS-related remote code execution, information disclosure, and denial-of-service (DoS) issues that can be triggered via DNS or DHCP. &q

Equifax data breach was bigger than initially reported, exposing highly sensitive information of more Americans than previously revealed. Credit rating agency Equifax says an additional 2.5 million U.S. consumers were also impacted by the massive data breach the company disclosed last month, bringing the total possible victims to 145.5 million from 143 million. Equifax last month announced that it had suffered a massive data breach that exposed highly sensitive data of hundreds of millions of its customers, which includes names, social security numbers, dates of birth and addresses. In addition, credit card information for nearly 209,000 customers was also stolen, as well as certain documents with personally identifying information (PII) for approximately 182,000 Equifax consumers. The breach was due to a critical vulnerability ( CVE-2017-5638 ) in Apache Struts 2 framework, which Apache patched over two months earlier (on March 6) of the security incident. Equifax was e

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

Mining cryptocurrencies can be a costly investment as it takes a monstrous amount of computing power, and thus hackers have started using malware that steals computing resources of computers it hijacks to make lots of dollars in digital currency. Security researchers at security firm ESET have spotted one such malware that infected hundreds of Windows web servers with a malicious cryptocurrency miner and helped cybercriminals made more than $63,000 worth of Monero (XMR) in just three months. According to a report published by ESET today, cybercriminals only made modifications to legitimate open source Monero mining software and exploited a known vulnerability in Microsoft IIS 6.0 to secretly install the miner on unpatched Windows servers. Although ESET's investigation does not identify the attackers, it reports that the attackers have been infecting unpatched Windows web servers with the cryptocurrency miner since at least May 2017 to mine 'Monero,' a Bitcoin-like

A bug in Linux kernel that was discovered two years ago, but was not considered a security threat at that time, has now been recognised as a potential local privilege escalation flaw. Identified as CVE-2017-1000253, the bug was initially discovered by Google researcher Michael Davidson in April 2015. Since it was not recognised as a serious bug at that time, the patch for this kernel flaw was not backported to long-term Linux distributions in kernel 3.10.77. However, researchers at Qualys Research Labs has now found that this vulnerability could be exploited to escalate privileges and it affects all major Linux distributions, including Red Hat, Debian, and CentOS. The vulnerability left "all versions of CentOS 7 before 1708 (released on September 13, 2017), all versions of Red Hat Enterprise Linux 7 before 7.4 (released on August 1, 2017), and all versions of CentOS 6 and Red Hat Enterprise Linux 6 are exploitable," Qualys said in an advisory published yesterday.

It seems like Tor Browser zero-day exploits are in high demand right now—so much so that someone is ready to pay ONE MILLION dollars. Zerodium—a company that specialises in acquiring and reselling zero-day exploits—just announced that it will pay up to USD 1,000,000 for working zero-day exploits for the popular Tor Browser on Tails Linux and Windows operating system. Tor browser users should take this news an early warning, especially who use Tails OS to protect their privacy. Zero-day exploit acquisition platform has also published some rules and payout details on its website, announcing that the payout for Tor exploits with no JavaScript has been kept double than those with JavaScript enabled. The company has also clearly mentioned that the exploit must leverage remote code execution vulnerability, the initial attack vector should be a web page and it should work against the latest version of Tor Browser. Moreover, the zero-day Tor exploit must work without requiring an

Here's the list of publically known flaws and their impact: W

Adobe may kill Flash Player by the end of 2020, but until then, the company would not stop providing security updates to the buggy software . As part of its monthly security updates, Adobe has released patches for eight security vulnerabilities in its three products, including two vulnerabilities in Flash Player, four in ColdFusion, and two in RoboHelp—five of these are rated as critical. Both of the Adobe Flash Player vulnerabilities can be exploited for remote code execution on the affected device, and both have been classified as critical. None of the patched vulnerabilities has reportedly been exploited in the wild, according to the company. The critical Flash Player flaws are tracked as CVE-2017-11281 and CVE-2017-11282 and were discovered by Mateusz Jurczyk and Natalie Silvanovich of Google Project Zero, respectively. Both the security vulnerabilities are memory corruption issues that could lead to remote code execution and affect all major operating system, includi

If you are using a Bluetooth enabled device, be it a smartphone, laptop, smart TV or any other IoT device, you are at risk of malware attacks that can carry out remotely to take over your device even without requiring any interaction from your side. Security researchers have just discovered total 8 zero-day vulnerabilities in Bluetooth protocol that impact more than 5.3 Billion devices—from Android, iOS, Windows and Linux to the Internet of things (IoT) devices—using the short-range wireless communication technology. Using these vulnerabilities, security researchers at IoT security firm Armis have devised an attack, dubbed BlueBorne , which could allow attackers to completely take over Bluetooth-enabled devices, spread malware, or even establish a "man-in-the-middle" connection to gain access to devices' critical data and networks without requiring any victim interaction. All an attacker need is for the victim's device to have Bluetooth turned on and obvious

After Equifax massive data breach that was believed to be caused due to a vulnerability in Apache Struts , Cisco has initiated an investigation into its products that incorporate a version of the popular Apache Struts2 web application framework. Apache Struts is a free, open-source MVC framework for developing web applications in the Java programming language, and used by 65 percent of the Fortune 100 companies, including Lockheed Martin, Vodafone, Virgin Atlantic, and the IRS. However, the popular open-source software package was recently found affected by multiple vulnerabilities, including two remote code execution vulnerabilities—one discovered earlier this month, and another in March—one of which is believed to be used to breach personal data of over 143 million Equifax users . Some of Cisco products including its Digital Media Manager, MXE 3500 Series Media Experience Engines, Network Performance Analysis, Hosted Collaboration Solution for Contact Center, and Unified C

With the growing number of cyber attacks and data breaches, a number of tech companies and organisations have started Bug Bounty programs for encouraging hackers, bug hunters and researchers to find and responsibly report bugs in their services and get rewarded. Samsung is the latest in the list of tech companies to launch a bug bounty program, announcing that the South Korean electronics giant will offer rewards of up to $200,000 to anyone who discovers vulnerabilities in its mobile devices and associated software. Dubbed Mobile Security Rewards Program , the newly-launched bug bounty program will cover 38 Samsung mobile devices released from 2016 onwards which currently receive monthly or quarterly security updates from the company. So, if you want to take part in the Samsung Mobile Security Rewards Program, you have these devices as your target—the Galaxy S, Galaxy Note, Galaxy A, Galaxy J, and the Galaxy Tab series, as well as Samsung's flagship devices, the S8, S8+, a

A security researcher has discovered not one or two but a total of ten critical zero-day vulnerabilities in routers from Taiwan-based networking equipment manufacturer D-Link which leave users open to cyber attacks. D-Link DIR 850L wireless AC1200 dual-band gigabit cloud routers are vulnerable to 10 security issues, including "several trivial" cross-site scripting (XSS) flaws, lack of proper firmware protection, backdoor access, and command injection attacks resulting in root access. If successfully exploited, these vulnerabilities could allow hackers to intercept connection, upload malicious firmware, and get root privileges, enabling them to remotely hijack and control affected routers, as well as network, leaving all connected devices vulnerable to cyber attacks as well. These zero-day vulnerabilities were discovered by Pierre Kim —the same security researcher who last year discovered and reported multiple severe flaws in D-Link DWR-932B LTE router, but the company

Internet-of-things are turning every industry into the computer industry, making customers think that their lives would be much easier with smart devices. However, such devices could potentially be compromised by hackers. There are, of course, some really good reasons to connect certain devices to the Internet. But does everything need to be connected? Of course, not—especially when it comes to medical devices. Medical devices are increasingly found vulnerable to hacking. Earlier this month, the US Food and Drug Administration (FDA) recalled 465,000 pacemakers after they were found vulnerable to hackers. Now, it turns out that a syringe infusion pump used in acute care settings could be remotely accessed and manipulated by hackers to impact the intended operation of the device, ICS-CERT warned in an advisory issued on Thursday. An independent security researcher has discovered not just one or two, but eight security vulnerabilities in the Medfusion 4000 Wireless Syringe

Germany's democracy is in danger, as the upcoming federal elections in the country, where nearly 61.5 million citizens are going to vote on September 24th, could be hijacked. Hackers have disclosed how to hack the German voting software to tamper with votes and alter the outcome of an election. Yes, election hacking is no theory—it is happening. A team of researchers from German hacking group Chaos Computer Club (CCC) has discovered several critical vulnerabilities in PC-Wahl—software used to capture, tabulate and transfer the votes from local polling centres to the state level during all parliamentary elections for decades. According to the CCC analysis, vulnerabilities could lead to multiple practicable attack scenarios that eventually allow malicious agents in the electoral office to change total vote counts. Critical Flaws Found In German Voting-Software The hacker collective found that the automatic software update module of PC-Wahl downloads packages over in

Security researchers have discovered several severe zero-day vulnerabilities in the mobile bootloaders from at least four popular device manufacturers that could allow an attacker to gain persistent root access on the device. A team of nine security researchers from the University of California Santa Barbara created a special static binary tool called BootStomp that automatically detects security vulnerabilities in bootloaders. Since bootloaders are usually closed source and hard to reverse-engineer, performing analysis on them is difficult, especially because hardware dependencies hinder dynamic analysis. Therefore, the researchers created BootStomp, which "uses a novel combination of static analysis techniques and underconstrained symbolic execution to build a multi-tag taint analysis capable of identifying bootloader vulnerabilities." The tool helped the researchers discover six previously-unknown critical security bugs across bootloaders from HiSilicon (Huawe

Security researchers have discovered a critical remote code execution vulnerability in the popular Apache Struts web application framework, allowing a remote attacker to run malicious code on the affected servers. Apache Struts is a free, open-source, Model-View-Controller (MVC) framework for developing web applications in the Java programming language, which supports REST, AJAX, and JSON. The vulnerability (CVE-2017-9805) is a programming blunder that resides in the way Struts processes data from an untrusted source. Specifically, Struts REST plugin fails to handle XML payloads while deserializing them properly. All versions of Apache Struts since 2008 (Struts 2.1.2 - Struts 2.3.33, Struts 2.5 - Struts 2.5.12) are affected, leaving all web applications using the framework's REST plugin vulnerable to remote attackers. According to one of the security researchers at LGTM, who discovered this flaw, the Struts framework is being used by "an incredibly large number and va

Are you using Foxit PDF Reader? If yes, then you need to watch your back. Security researchers have discovered two critical zero-day security vulnerabilities in Foxit Reader software that could allow attackers to execute arbitrary code on a targeted computer, if not configured to open files in the Safe Reading Mode. The first vulnerability (CVE-2017-10951) is a command injection bug discovered by researcher Ariele Caltabiano working with Trend Micro's Zero Day Initiative (ZDI), while the second bug (CVE-2017-10952) is a file write issue found by Offensive Security researcher Steven Seeley. An attacker can exploit these bugs by sending a specially crafted PDF file to a Foxit user and enticing them to open it. Foxit refused to patch both the vulnerabilities because they would not work with the "safe reading mode" feature that fortunately comes enabled by default in Foxit Reader. "Foxit Reader & PhantomPDF has a Safe Reading Mode which is enabled by d

Today, many automobiles companies are offering vehicles that run on the mostly drive-by-wire system, which means a majority of car's functions—from instrument cluster to steering, brakes, and accelerator—are electronically controlled. No doubt these auto-control systems make your driving experience much better, but at the same time, they also increase the risk of getting hacked. Car Hacking is a hot topic, though it is not new for security researchers who hack cars. A few of them have already demonstrated how to hijack a car remotely , how to disable car's crucial functions like airbags, and even how to remotely steal cars . Now, security researchers have discovered a new hacking trick that can allow attackers to disable airbags and other safety systems of the connected cars, affecting a large number of vendors and vehicle models. A team of researchers from Trend Micro's Forward-looking Threat Research (FTR) team, in collaboration with Politecnico di Milano and

Do you know — 1 Gram of DNA Can Store 1,000,000,000 Terabyte of Data for 1000+ Years? Even in March this year, a team of researchers successfully stored digital data — an entire operating system, a movie, an Amazon gift card, a study and a computer virus — in the strands of DNA. But what if someone stores a malicious program into the DNA, just like an infected USB storage, to hijack the computer that reads it. A team of researchers from the University of Washington in Seattle have demonstrated the first successful DNA-based exploit of a computer system that executes the malicious code written into the synthesised DNA strands while reading it. To carry out the hack, the researchers created biological malware and encoded it in a short stretch of DNA, which allowed them to gain "full control" of a computer that tried to process the genetic data when read by a DNA sequencing machine. The DNA-based hack becomes possible due to lack of security in multiple DNA proces

A Dutch security researcher has uncovered a slew of security vulnerabilities in an essential component of solar panels which could be exploited to cause widespread outages in European power grids. Willem Westerhof, a cybersecurity researcher at Dutch security firm ITsec, discovered 21 security vulnerabilities in the Internet-connected inverters – an essential component of solar panel that turns direct current (DC) into alternating current (AC). According to Westerhof, the vulnerabilities leave thousands of Internet-connected power inverters installed across Europe vulnerable. Westerhof demonstrates that it is possible for hackers to gain control of a large number of inverters and switch them OFF simultaneously, causing an imbalance in the power grid that could result in power outages in different parts of Europe. The vulnerabilities affect solar panel electricity systems, also known as photovoltaics (PV), made by German solar equipment company SMA, which if exploited in mass
