Samba maintainers have just released new versions of their networking software to patch two critical vulnerabilities that could allow unprivileged remote attackers to launch DoS attacks against servers and change any other users' passwords, including admin's. 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 denial of service vulnerability, assigned CVE-2018-1050 , affects all versions of Samba from 4.0.0 onwards and could be exploited "when the RPC spoolss service is configured to be run as an external daemon." "Missing input sanitization checks on some of the input parameters to spoolss RPC calls could cause the print spooler service to crash.

Nothing comes for free, especially online. Would you be okay with allowing a few paid services to mine cryptocurrencies using your system instead of paying the subscription fee? Most free websites and services often rely on advertising revenue to survive, but now there is a new way to make money—using customers' computer to generate virtual currencies. It was found that a scheduling app, dubbed Calendar 2, was embracing cryptocurrency mining in exchange for free access to its app premium features, but the developer has to take it down from the Apple App Store following reports that it's not working as intended. Cryptocurrency mining is not a new concept, but the technology has recently exploded after hackers found it a great way to make millions of dollars by hijacking computers to secretly perform cryptocurrency mining in the background without users' knowledge or consent. Due to this cryptocurrency mining has emerged as one of the biggest threats in recent mon

Over the past two years, a shocking  51% of organizations surveyed in a leading industry report have been compromised by a cyberattack.  Yes, over half.  And this, in a world where enterprises deploy  an average of 53 different security solutions  to safeguard their digital domain.  Alarming? Absolutely. A recent survey of CISOs and CIOs, commissioned by Pentera and conducted by Global Surveyz Research, offers a quantifiable glimpse into this evolving battlefield, revealing a stark contrast between the growing risks and the tightening budget constraints under which cybersecurity professionals operate. With this report, Pentera has once again taken a magnifying glass to the state of pentesting to release its annual report about today's pentesting practices. Engaging with 450 security executives from North America, LATAM, APAC, and EMEA—all in VP or C-level positions at organizations with over 1,000 employees—the report paints a current picture of modern security validation prac

The team of security researchers—who last month demonstrated how attackers could steal data from air-gapped computers protected inside a Faraday cage—are back with its new research showing how two (or more) air-gapped PCs placed in the same room can covertly exchange data via ultrasonic waves. Air-gapped computers are believed to be the most secure setup wherein the systems remain isolated from the Internet and local networks, requiring physical access to access data via a USB flash drive or other removable media. Dubbed MOSQUITO , the new technique, discovered by a team of researchers at Israel's Ben Gurion University, works by reversing connected speakers (passive speakers, headphones, or earphones) into microphones by exploiting a specific audio chip feature. Two years ago, the same team of researchers demonstrated how attackers could covertly listen to private conversations in your room just by reversing your headphones (connected to the infected computer) into a micr

Security researchers at Kaspersky have identified a sophisticated APT hacking group that has been operating since at least 2012 without being noticed due to their complex and clever hacking techniques. The hacking group used a piece of advanced malware—dubbed Slingshot —to infect hundreds of thousands of victims in the Middle East and Africa by hacking into their routers. According to a 25-page report published [ PDF ] by Kaspersky Labs, the group exploited unknown vulnerabilities in routers from a Latvian network hardware provider Mikrotik as its first-stage infection vector in order to covertly plant its spyware into victims' computers. Although it is unclear how the group managed to compromise the routers at the first place, Kaspersky pointed towards WikiLeaks Vault 7 CIA Leaks , which revealed the ChimayRed exploit , now available on GitHub , to compromise Mikrotik routers. Once the router is compromised, the attackers replace one of its DDL (dynamic link libraries)

Governments in Turkey and Syria have been caught hijacking local internet users' connections to secretly inject surveillance malware, while the same mass interception technology has been found secretly injecting browser-based cryptocurrency mining scripts into users' web traffic in Egypt. Governments, or agencies linked to it, and ISPs in the three countries are using Deep Packet Inspection technology from Sandvine (which merged with Procera Networks last year), to intercept and alter Internet users' web traffic. Deep packet inspection technology allows ISPs to prioritize, degrade, block, inject, and log various types of Internet traffic, in other words, they can analyze each packet in order to see what you are doing online. According to a new report by Citizen Lab, Turkey's Telecom network was using Sandvine PacketLogic devices to redirect hundreds of targeted users (journalists, lawyers, and human rights defenders) to malicious versions of legitimate progra

Memcached reflections that recently fueled two most largest amplification DDoS attacks in the history have also helped other cybercriminals launch nearly 15,000 cyber attacks against 7,131 unique targets in last ten days, a new report revealed. Chinese Qihoo 360's Netlab, whose global DDoS monitoring service ' DDosMon ' initially spotted the Memcached-based DDoS attacks, has published a blog post detailing some new statistics about the victims and sources of these attacks. The list of famous online services and websites which were hit by massive DDoS attacks since 24th February includes Google, Amazon, QQ.com, 360.com, PlayStation, OVH Hosting, VirusTotal, Comodo, GitHub ( 1.35 Tbps attack ), Royal Bank, Minecraft and RockStar games, Avast, Kaspersky, PornHub, Epoch Times newspaper, and Pinterest. Overall, the victims are mainly based in the United States, China, Hong Kong, South Korea, Brazil, France, Germany, the United Kingdom, Canada, and the Netherlands.

Microsoft has confirmed that the company is planning to convert Windows 10 S from a dedicated operating system to a special " S Mode " that will be available in all versions of Windows. Windows 10 S, a new operating system designed for simplicity, security, and speed, was released by Microsoft last year. It locks a computer down to run applications only downloaded from official Windows Store, but the slimmed-down and restricted flavor of Windows did not exactly turn out to be a success. Therefore, the company has now decided Windows 10 S be offered as an optional mode rather than a dedicated operating system. Windows 10 S was developed to simplify administration for school or business sysadmins that want the 'low-hassle' guaranteed performance version. It has been designed to deliver predictable performance and quality through Microsoft-verified apps via the Microsoft Store. However, in a blog post published Wednesday, the corporate VP of Microsoft's

Two days ago, Microsoft encountered a rapidly spreading cryptocurrency-mining malware that infected almost 500,000 computers within just 12 hours and successfully blocked it to a large extent. Dubbed Dofoil , aka Smoke Loader , the malware was found dropping a cryptocurrency miner program as payload on infected Windows computers that mines Electroneum coins, yet another cryptocurrency, for attackers using victims' CPUs. On March 6, Windows Defender suddenly detected more than 80,000 instances of several variants of Dofoil that raised the alarm at Microsoft Windows Defender research department, and within the next 12 hours, over 400,000 instances were recorded. The research team found that all these instances, rapidly spreading across Russia, Turkey, and Ukraine, were carrying a digital coin-mining payload, which masqueraded as a legitimate Windows binary to evade detection. However, Microsoft has not mentioned how these instances were delivered to such a massive audienc
