A critical vulnerability has been discovered in Systemd , the popular init system and service manager for Linux operating systems, that could allow remote attackers to potentially trigger a buffer overflow to execute malicious code on the targeted machines via a DNS response. The vulnerability, designated as CVE-2017-9445 , actually resides in the ' dns_packet_new ' function of 'systemd-resolved,' a DNS response handler component that provides network name resolution to local applications. According to an advisory published Tuesday, a specially crafted malicious DNS response can crash 'systemd-resolved' program remotely when the system tries to lookup for a hostname on an attacker-controlled DNS service. Eventually, large DNS response overflows the buffer, allowing an attacker to overwrite the memory which leads to remote code execution. This means the attackers can remotely run any malware on the targeted system or server via their evil DNS service...

What if I say the Tuesday's devastating global malware outbreak was not due to any ransomware infection? Yes, the Petya ransomware attacks that began infecting computers in several countries, including Russia, Ukraine, France, India and the United States on Tuesday and demands $300 ransom was not designed with the intention of restoring the computers at all. According to a new analysis, the virus was designed to look like ransomware but was wiper malware that wipes computers outright, destroying all records from the targeted systems. Comae Technologies Founder Matt Suiche, who closely looked the operation of the malware, said after analyzing the virus, known as Petya, his team found that it was a " Wiper malware ," not ransomware. Security experts even believe the real attack has been disguised to divert world's attention from a state-sponsored attack on Ukraine to a malware outbreak. "We believe the ransomware was, in fact, a lure to control the...

Microsoft is making every effort to make its Windows operating system more secure and advanced than ever before by beefing up its security practices and hardening it against hackers and cyber attacks in its next release. With the launch of its Windows 10 Creator Update (also known as RedStone 3), which is expected to release sometime between September and October 2017, Microsoft is planning to release lots of security features in an effort to prevent major global malware crisis. Just a few days ago, we reported about Microsoft's plan to build its EMET or Enhanced Mitigation Experience Toolkit into the kernel of the upcoming Windows 10 to boost the security of your computer against complex threats such as zero-day vulnerabilities. Also, the tech giant has planned to remove the SMBv1 (Server Message Block version 1) — a 30-year-old file sharing protocol which came to light last month after the devastating WannaCry outbreak — from the upcoming Windows 10 (1709) Redstone 3 ...

WikiLeaks has just published a new batch of the ongoing Vault 7 leak , and this time the whistleblowing website has unveiled a classified malware for that tracks geo-location of targeted PCs and laptops running the Microsoft Windows operating system. In short, the malware does it by capturing the IDs of nearby public hotspots and then matching them with the global database of public Wi-Fi hotspots' locations. Dubbed ELSA , the alleged CIA's project consists of two main elements: the processing component (Operator Terminal) and the implant (Windows Target) which is typically being deployed on a target Windows host. Here's How the CIA's ELSA Malware Works The Elsa system first installs the malware on a targeted WiFi-enabled machine using separate CIA exploits to gain persistent access on the device. The malware then uses Wi-Fi hardware of the infected computer to scan nearby visible WiFi access points (AP) and records their ESSID – stands for Extended Service Se...

The Shadow Brokers , a notorious hacking group that leaked US cyberweapons — which were also abused by the recent ransomware disasters WannaCry and Petya or NotPetya — has now threatened to unmask the identity of a former hacker who worked for the NSA. Besides this, the Shadow Brokers group has also doubled the price for its monthly subscription model of NSA's built hacking tools and zero-day exploits from 100 ZEC (Zcash) to 200 ZEC, which is around $64,400 USD. Moreover, the hacking group has also announced a VIP service for people, who will be entertained by the group for their queries on the leaked hacking tools and exploits. To subscribe to the VIP service, one has to make a one-time payment of 400 ZEC (around US$128,800). Last month, the Shadow Brokers announced to release more zero-days exploits and hacking tools  developed by the US spy agency every month from June 2017, but only to private members who will subscribe for receiving exclusive access to the futur...

A critical vulnerability has been discovered in Microsoft-owned most popular free web messaging and voice calling service Skype that could allow hackers to remotely execute malicious code and crash systems. Skype is a free online service that allows users to communicate with peers by voice, video, and instant messaging over the Internet.

Watch out, readers! It is ransomware, another WannaCry, another wide-spread attack. The WannaCry ransomware is not dead yet and another large scale ransomware attack is making chaos worldwide, shutting down computers at corporates, power supplies, and banks across Russia, Ukraine, Spain, France, UK, India, and Europe and demanding $300 in bitcoins. According to multiple sources, a new variant of Petya ransomware , also known as Petwrap, is spreading rapidly with the help of same Windows SMBv1 vulnerability that the WannaCry ransomware abused to infect 300,000 systems and servers worldwide in just 72 hours last month. Apart from this, many victims have also informed that Petya ransomware has also infected their patch systems. "Petya uses the NSA Eternalblue exploit but also spreads in internal networks with WMIC and PSEXEC. That's why patched systems can get hit." Mikko Hypponen  confirms , Chief Research Officer at F-Secure. Petya is a nasty piece of rans...

Google has just lost its biggest regulatory battle! Google has been hit with a record-breaking $2.7 billion (€2.42 billion) fine by the European antitrust officials for unfairly manipulating search results since 2008. After a lengthy seven-year investigation that was launched in 2010 after several rivals complaint, the European Commission on Tuesday imposed this 'biggest even financial penalty' against the internet tech giant for breaking EU competition law. by using its search dominance to distort search-engine results to promote own shopping comparison service at the top of all search results. "Comparison shopping services rely to a large extent on traffic to be competitive." European Commission says in a press release . "The evidence shows that consumers click far more often on results that are more visible, i.e. the results appearing higher up in Google's search results. More traffic leads to more clicks and generates revenue." The Comm...

Russia has threatened to ban Telegram end-to-end encrypted messaging app, after Pavel Durov, its founder, refused to sign up to the country's new data protection laws. Russian intelligence service, the FSB, said on Monday that the terrorists that killed 15 people in Saint Petersburg in April had used the Telegram encrypted messaging service to plot their attacks. According to the new Russian Data Protection Laws, as of January 1, all foreign tech companies have been required to store the past six months' of the personal data of its citizens and encryption keys within the country; which the company has to share with the authorities on demand.

A massive archive of Microsoft's top-secret Windows 10 builds, and the source codes for private software has been reportedly leaked online, which could lead to a nasty wave of Windows 10 exploits, journalist at the Reg claims. The Leaked files – uploaded on BetaArchive website – contains more than 32 terabytes of data, which includes many non-public Windows 10 and Windows Server 2016 builds created by Microsoft engineers for testing purpose. Interestingly, Windows 10 internal builds include private debugging symbols defined by the engineers usually to help other in-house developers understand how some specific codes in the operating system works and what functions it calls, the Register reports . Private debugging symbols reveal some sensitive in-depth knowledge about the operating system that could be used by exploit writers to find vulnerabilities. Moreover, the dump also contains Microsoft's Shared Source Kit , which includes source code for Windows 10 hardware ...

British police have arrested two men in the UK conspiring to hack into the computer networks of US tech giant Microsoft with plans to steal customers' data from the software giant. The suspects — 22-year-old from Sleaford and a 25-year-old from Bracknell — were arrested by the detectives from the Britain's South East Regional Organised Crime Unit (SEROCU) Thursday morning (22 June 2017). The UK authorities arrested them from their home in Lincolnshire and Bracknell and seized a number of devices after searching their home. While it is still unclear what systems were targeted, SEROCU believes the suspects are part of a larger international group that involved breaking into the Microsoft's network between January 2017 and March 2017 to scoop up the customer information. "This group is spread around the world and therefore the investigation is being coordinated with our various partners," Rob Bryant, detective sergeant SEROCU's Cyber Crime Unit said while ...

Vulnerabilities discovered in Microsoft PatchGuard kernel protection could allow hackers to plant rootkits on computers running the company's latest and secure operating system, Windows 10. Researchers at CyberArk Labs have developed a new attack technique which could allow hackers to completely bypass PatchGuard, and hook a malicious kernel code (rootkits) at the kernel level. PatchGuard, or (or Kernel Patch Protection) is a software tool that has been designed to forbid the kernel of 64-bit versions of Windows OS from being patched, preventing hackers from running rootkits or executing malicious code at the kernel level. Dubbed GhostHook , the attack is what the CyberArk Labs researchers call the first attack technique that thwarts the defensive technology to bypass PatchGuard, though it requires a hacker to already be present on a compromised system and running code in the kernel. So, basically, this is a post-exploitation attack. "[GhostHook] is neither an ...
