A security researcher has discovered a code injection vulnerability in the thumbnail handler component of GNOME Files file manager that could allow hackers to execute malicious code on targeted Linux machines. Dubbed Bad Taste , the vulnerability ( CVE-2017-11421 ) was discovered by German researcher Nils Dagsson Moskopp, who also released proof-of-concept code on his blog to demonstrate the vulnerability. The code injection vulnerability resides in "gnome-exe-thumbnailer"  — a tool to generate thumbnails from Windows executable files (.exe/.msi/.dll/.lnk) for GNOME, which requires users to have Wine application installed on their systems to open it. Those who are unaware, Wine is a free and open-source software that allows Windows applications to run on the Linux operating system. Moskopp discovered that while navigating to a directory containing the .msi file, GNOME Files takes the filename as an executable input and run it in order to create an image thumbna

An unknown hacker has just stolen nearly $32 million worth of Ethereum – one of the most popular and increasingly valuable cryptocurrencies – from Ethereum wallet accounts linked to at least three companies that seem to have been hacked. This is the third Ethereum cryptocurrency heist that came out two days after an alleged hacker stole $7.4 million worth of Ether from trading platform CoinDash, and two weeks after an unknown attacker hacked into South Korean cryptocurrency exchange Bithumb and stole more than $1 Million in Ether and Bitcoins from user accounts. On Wednesday, Smart contract coding company Parity issued a security alert , warning of a critical vulnerability in Parity's Ethereum Wallet software, which is described as "the fastest and most secure way of interacting with the Ethereum network." Exploiting the vulnerability allowed attackers to compromise at least three accounts and steal nearly 153,000 units of Ether worth just almost US$32 million

It comes as no surprise that today's cyber threats are orders of magnitude more complex than those of the past. And the ever-evolving tactics that attackers use demand the adoption of better, more holistic and consolidated ways to meet this non-stop challenge. Security teams constantly look for ways to reduce risk while improving security posture, but many approaches offer piecemeal solutions – zeroing in on one particular element of the evolving threat landscape challenge – missing the forest for the trees.  In the last few years, Exposure Management has become known as a comprehensive way of reigning in the chaos, giving organizations a true fighting chance to reduce risk and improve posture. In this article I'll cover what Exposure Management is, how it stacks up against some alternative approaches and why building an Exposure Management program should be on  your 2024 to-do list. What is Exposure Management?  Exposure Management is the systematic identification, evaluation,

If you are hoverboard rider, you should be concerned about yourself. Thomas Kilbride, a security researcher from security firm IOActive, have discovered several critical vulnerabilities in Segway Ninebot miniPRO that could be exploited by hackers to remotely take "full control" over the hoverboard within range and leave riders out-of-control. Segway Ninebot miniPRO is a high-speed, self-balancing, two-wheel, hands-free electric scooter, also known as SUV of hoverboards, which also allows it riders to control the hoverboard by a Ninebot smartphone app remotely. Ninebot smartphone app allows riders to adjust light colours, modify safety features, run vehicle diagnostics, set anti-theft alarms, and even remotely commanding the miniPRO scooter to move. But the security of powerful miniPRO was so sick that Thomas hardly took 20 seconds to hack it and hijack remote control of it. In a blog post published today, Thomas has disclosed a series of critical security vul

As part of its ongoing Vault 7 leaks , the whistleblower organisation WikiLeaks today revealed about a CIA contractor responsible for analysing advanced malware and hacking techniques being used in the wild by cyber criminals. According to the documents leaked by WikiLeaks, Raytheon Blackbird Technologies, the Central Intelligence Agency (CIA) contractor, submitted nearly five such reports to CIA as part of UMBRAGE Component Library (UCL) project between November 2014 and September 2015. These reports contain brief analysis about proof-of-concept ideas and malware attack vectors — publically presented by security researchers and secretly developed by cyber espionage hacking groups. Reports submitted by Raytheon were allegedly helping CIA's Remote Development Branch (RDB) to collect ideas for developing their own advanced malware projects. It was also revealed in previous Vault 7 leaks that CIA's UMBRAGE malware development teams also borrow codes from publicly avail

Remember SambaCry ? Almost two months ago, we reported about a 7-year-old critical remote code execution vulnerability in Samba networking software, allowing a hacker to remotely take full control of a vulnerable Linux and Unix machines. We dubbed the vulnerability as SambaCry, because of its similarities to the Windows SMB vulnerability exploited by the WannaCry ransomware that wreaked havoc across the world over two months ago. Despite being patched in late May, the vulnerability is currently being leveraged by a new piece of malware to target the Internet of Things (IoT) devices, particularly Network Attached Storage (NAS) appliances, researchers at Trend Micro warned . For those unfamiliar: Samba is open-source software (re-implementation of SMB/CIFS networking protocol), which offers Linux/Unix servers with Windows-based file and print services and runs on the majority of operating systems, including Linux, UNIX, IBM System 390, and OpenVMS. Shortly after the publi

Security researchers have discovered a critical remotely exploitable vulnerability in an open-source software development library used by major manufacturers of the Internet-of-Thing devices that eventually left millions of devices vulnerable to hacking. The vulnerability (CVE-2017-9765), discovered by researchers at the IoT-focused security firm Senrio, resides in the software development library called gSOAP toolkit (Simple Object Access Protocol) — an advanced C/C++ auto-coding tool for developing XML Web services and XML application. Dubbed " Devil's Ivy ," the stack buffer overflow vulnerability allows a remote attacker to crash the SOAP WebServices daemon and could be exploited to execute arbitrary code on the vulnerable devices. The Devil's Ivy vulnerability was discovered by researchers while analysing an Internet-connected security camera manufactured by Axis Communications. "When exploited, it allows an attacker to remotely access a video

Nothing in this world is fully secure, from our borders to cyberspace. I know vulnerabilities are bad, but the worst part comes in when people just don't care to apply patches on time. Late last year, Cisco's Talos intelligence and research group discovered three critical remote code execution (RCE) vulnerabilities in Memcached that exposed major websites including Facebook, Twitter, YouTube, Reddit, to hackers. Memcached is a popular open-source and easily deployable distributed caching system that allows objects to be stored in memory. The Memcached application has been designed to speed up dynamic web applications ( for example php-based websites) by reducing stress on the database that helps administrators to increase performance and scale web applications. It's been almost eight months since the Memcached developers have released patches for three critical RCE vulnerabilities (CVE-2016-8704, CVE-2016-8705 and CVE-2016-8706) but tens of thousands of servers
