A high-severity vulnerability has been reported in Linux that could be exploited by a low privilege attacker to gain full root access on an affected system. The vulnerability, identified as CVE-2017-1000367, was discovered by researchers at Qualys Security in Sudo's "get_process_ttyname()" function for Linux that could allow a user with Sudo privileges to run commands as root or elevate privileges to root. Sudo, stands for "superuser do!," is a program for Linux and UNIX operating systems that lets standard users run specific commands as a superuser (aka root user), such as adding users or performing system updates. The flaw actually resides in the way Sudo parsed "tty" information from the process status file in the proc filesystem. On Linux machines, sudo parses the /proc/[pid]/stat file in order to determine the device number of the process's tty from field 7 (tty_nr), Qualys Security explains in its advisory . Although the fields in t

Sensitive files linked to the United States intelligence agency were reportedly left on a public Amazon server by one of the nation's top intelligence contractor without a password, according to a new report. UpGuard cyber risk analyst Chris Vickery discovered  a cache of 60,000 documents from a US military project for the National Geospatial-Intelligence Agency (NGA) left unsecured on Amazon cloud storage server for anyone to access. The documents included passwords to a US government system containing sensitive information, and the security credentials of a senior employee of Booz Allen Hamilton, one of the country's top defense contractors. Although there wasn't any top secret file in the cache Vickery discovered, the documents included credentials to log into code repositories that could contain classified files and other credentials. Master Credentials to a Highly-Protected Pentagon System were Exposed Roughly 28GB of exposed documents included the privat

Follow this real-life network attack simulation, covering 6 steps from Initial Access to Data Exfiltration. See how attackers remain undetected with the simplest tools and why you need multiple choke points in your defense strategy. Surprisingly, most network attacks are not exceptionally sophisticated, technologically advanced, or reliant on zero-day tools that exploit edge-case vulnerabilities. Instead, they often use commonly available tools and exploit multiple vulnerability points. By simulating a real-world network attack, security teams can test their detection systems, ensure they have multiple choke points in place, and demonstrate the value of networking security to leadership. In this article, we demonstrate a real-life attack that could easily occur in many systems. The attack simulation was developed based on the MITRE ATT&CK framework, Atomic Red Team,  Cato Networks ' experience in the field, and public threat intel. In the end, we explain why a holistic secur

The alleged Russian hacker, who was arrested by the Czech police in Prague last October on suspicion of massive 2012 data breach at LinkedIn, can be extradited to either the United States or Russia, a Czech court ruled on Tuesday. Yevgeniy Aleksandrovich Nikulin , a 29-years-old Russian national, is accused of allegedly hacking not just LinkedIn , but also the online cloud storage platform Dropbox , and now-defunct social-networking company Formspring. However, he has repeatedly denied all accusations. Nikulin was arrested in Prague on October 5 by the Czech police after Interpol issued an international arrest warrant against him. Nikulin appeared at a court hearing held inside a high-security prison in Prague on Tuesday and emaciated after eight months in solitary confinement. The court ruling, pending appeals, left the final decision in the hands of Czech Justice Minister Robert Pelikan, who can approve extradition to one of the countries and block the other. The United

What if your laptop is listening to everything that is being said during your phone calls or other people near your laptop and even recording video of your surrounding without your knowledge? Sounds really scary! Isn't it? But this scenario is not only possible but is hell easy to accomplish. A UX design flaw in the Google's Chrome browser could allow malicious websites to record audio or video without alerting the user or giving any visual indication that the user is being spied on. AOL developer Ran Bar-Zik reported the vulnerability to Google on April 10, 2017, but the tech giant declined to consider this vulnerability a valid security issue, which means that there is no official patch on the way. How Browsers Works With Camera & Microphone Before jumping onto vulnerability details, you first need to know that web browser based audio-video communication relies on WebRTC (Web Real-Time Communications) protocol – a collection of communications protocols th

As promised to release more zero-days exploits and hacking tools for various platforms starting from June 2017, the infamous hacking group Shadow Brokers is back with more information on how to subscribe and become a private member for receiving exclusive access to the future leaks. The Shadow Brokers is the same hacking group who leaked NSA's built Windows hacking tools and zero-day exploits in public that led to the WannaCry menace . When the Shadow Brokers promised its June 2017 release two weeks ago, the group announced that it would sell new zero-day exploits and hacking tools only to the private members with paid monthly subscription, instead of making them public for everyone. How to Become Member of the 'Wine of Month' Club? Now, just a few minutes ago, the hacking collective has released details about how to participate in the monthly subscription model – or the "Wine of Month Club," as the group called it – to get exclusive access to the

It's been almost four weeks since the outcry of WannaCry ransomware , but the hackers behind the self-spread ransomware threat have not been identified yet. However, two weeks ago researchers at Google, Kaspersky Lab, Intezer and Symantec linked WannaCry to 'Lazarus Group,' a state-sponsored hacking group believed to work for the North Korean government. Now, new research from dark web intelligence firm Flashpoint indicates the perpetrators may be Chinese, based on its own linguistic analysis. Flashpoint researchers Jon Condra and John Costello analyzed each of WannaCry's localized ransom notes, which is available in 28 languages, for content, accuracy, and style, and discovered that all the notes, except English and Chinese versions (Simplified and Traditional), had been translated via Google Translate. According to the research, Chinese and English versions of the ransomware notes were most likely written by a human. On further analysis, researchers discovered that

Security researchers have claimed to have discovered possibly the largest malware campaign on Google Play Store that has already infected around 36.5 million Android devices with malicious ad-click software. The security firm Checkpoint on Thursday published a blog post revealing more than 41 Android applications from a Korean company on Google Play Store that make money for its creators by creating fake advertisement clicks from the infected devices. All the malicious apps, developed by Korea-based Kiniwini and published under the moniker ENISTUDIO Corp, contained an adware program, dubbed Judy, that is being used to generate fraudulent clicks to generate revenue from advertisements. Moreover, the researchers also uncovered a few more apps, published by other developers on Play Store, inexplicably containing the same the malware in them. The connection between the two campaigns remains unclear, though researchers believe it is possible that one developer borrowed code from

We came across so many revelations of sensitive government and corporate data on the Internet these days, but what's the accuracy of that information leaked by unknown actors? Security researchers have discovered new evidence of one such sophisticated global espionage and disinformation campaign with suspected ties to the Russian government that's been aimed to discredit enemies of the state. Although there is no definitive proof of Russian government's involvement in the campaign, there is "overlap" with previously reported cyber espionage activities tied to a Russia-backed hacking group well known as APT28 . APT28 — also known as Fancy Bear, Sofacy, Sednit, and Pawn Storm — is the same group which was responsible for the Democratic National Committee (DNC) breach. The group has been operating since at least 2007 and has alleged tied to the Russian government. A new report, titled Tainted Leaks , published this week by the Citizen Lab at the Univers

You may have heard of hilarious Nigerian scams. My all time favourite is this one: A Nigerian astronaut has been trapped in space for the past 25 years and needs $3 million to get back to Earth, Can you help? Moreover, Nigerians are also good at promising true love and happiness. But You know, Love hurts. Those looking for true love and happiness lost tens of millions of dollars over the Nigerian dating and romance scams. These criminals spend their whole day trolling the online dating sites for contact emails and then send off hundreds of thousands of fraudulent emails awaiting the victim's response. A US federal district court in Mississippi has sentenced such three Nigerian scammers to a collective 235 years in prison for their roles in a large-scale international fraud network that duped people out of tens of millions of dollars. The three Nigerian nationals were part of a 21-member gang of cyber criminals, of which six, including Ayelotan, Raheem, and Mewase,

Researchers have discovered a new attack, dubbed 'Cloak and Dagger', that works against all versions of Android, up to version 7.1.2. Cloak and Dagger attack allows hackers to silently take full control of your device and steal private data, including keystrokes, chats, device PIN, online account passwords, OTP passcode, and contacts. What's interesting about Cloak and Dagger attack? The attack doesn't exploit any vulnerability in Android ecosystem; instead, it abuses a pair of legitimate app permissions that is being widely used in popular applications to access certain features on an Android device. Researchers at Georgia Institute of Technology have discovered this attack, who successfully performed it on 20 people and none of them were able to detect any malicious activity. Cloak and Dagger attacks utilise two basic Android permissions: SYSTEM_ALERT_WINDOW ("draw on top") BIND_ACCESSIBILITY_SERVICE ("a11y") The first permissi

Brace yourselves for a possible 'second wave' of massive global cyber attack, as SMB ( Server Message Block) was not the only network protocol whose zero-day exploits created by NSA were exposed in the Shadow Brokers dump last month. Although Microsoft released patches for SMB flaws for supported versions in March and unsupported versions immediately after the outbreak of the WannaCry ransomware, the company ignored to patch other three NSA hacking tools, dubbed " EnglishmanDentist ," " EsteemAudit ," and " ExplodingCan ." It has been almost two weeks since WannaCry ransomware began to spread, which infected nearly 300,000 computers in more than 150 countries within just 72 hours, though now it has been slowed down. For those unaware, WannaCry exploited a Windows zero-day SMB bug that allowed remote hackers to hijack PCs running on unpatched Windows OS and then spread itself to other unpatched systems using its wormable capability.

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
