With a heavy heart, security researchers have early released the details of a set of vulnerabilities discovered in email clients for two widely used email encryption standards—PGP and S/MIME—after someone leaked their paper on the Internet, which was actually scheduled for tomorrow. PGP and S/MIME are popular end-to-end encryption standards used to encrypt emails in a way that no one, not even the company, government, or cyber criminals, can spy on your communication. Before explaining how the vulnerability works, it should be noted that the flaw doesn't reside in the email encryption standards itself; instead, it affects a few email clients/plugins that incorrectly implemented the technologies. Dubbed eFail by the researchers, the vulnerabilities, as described in our previous early-warning article , could allow potential attackers to decrypt the content of your end-to-end encrypted emails in plaintext, even for messages sent in the past. According to the paper released

Security researchers have discovered a severe vulnerability in the popular end-to-end encrypted Signal messaging app for Windows and Linux desktops which could allow remote attackers to execute malicious code on recipients system just by sending a message—without requiring any user interaction. Discovered by Alfredo Ortega, a software security consultant from Argentina, the vulnerability was announced on Twitter just a few hours ago with a proof-of-concept video, demonstrating how a javascript payload sent over Signal for desktop app successfully got executed on the recipient's system. Although technical details of the vulnerability have not been revealed as of now, the issue appears to be a remote code execution vulnerability in Signal or at least something very close to persistent cross-site scripting (XSS) which eventually could allow attackers to inject malicious code onto targeted Windows and Linux systems. "For the time being, we can only confirm the execution

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

It's time to gear up for the latest May 2018 Patch Tuesday. Microsoft has today released security patches for a total of 67 vulnerabilities, including two zero-days that have actively been exploited in the wild by cybercriminals, and two publicly disclosed bugs. In brief, Microsoft is addressing 21 vulnerabilities that are rated as critical, 42 rated important, and 4 rated as low severity. These patch updates address security flaws in Microsoft Windows, Internet Explorer, Microsoft Edge, Microsoft Office, Microsoft Office Exchange Server, Outlook, .NET Framework, Microsoft Hyper-V, ChakraCore, Azure IoT SDK, and more. 1) Double Kill IE 0-day Vulnerability The first zero-day vulnerability ( CVE-2018-8174 ) under active attack is a critical remote code execution vulnerability that was revealed by Chinese security firm Qihoo 360 last month and affected all supported versions of Windows operating systems. Dubbed " Double Kill " by the researchers, the vulnera

Security researchers revealed a way around that some hacking groups have been found using in the wild to bypass a security feature of Microsoft Office 365, which is originally designed to protect users from malware and phishing attacks. Dubbed Safe Links, the feature has been included in Office 365 software as part of Microsoft's Advanced Threat Protection (ATP) solution that works by replacing all URLs in an incoming email with Microsoft-owned secure URLs. So, every time a user clicks on a link provided in an email, it first sends the user to a Microsoft owned domain, where the company immediately checks the original URL for anything suspicious. If Microsoft's scanners detect any malicious element, it then warns users about it, and if not, it redirects the user to the original link. However, researchers at cloud security company Avanan have revealed how attackers have been bypassing the Safe Links feature by using a technique called, " baseStriker attack ."

Remember a young hacker who hacked jail systems in an attempt to release his prison inmate early? Well, that hacker will now be joining his inmate behind bars. Konrads Voits of Ypsilanti, Michigan, has been sentenced to seven years and three months in prison for attempting to hack the Washtenaw County Jail computer system and modifying prison records to get his friend released early. Besides spending 87 months in prison, Voits has also been ordered to pay $235,488 in fine to Washtenaw County for the cost accrued in investigating and cleaning up the infiltration that resulted in the compromise of personal information of around 1,600 employees, the US Justice Department announced last week. Between January 24th, 2017 and March 10th, 2017, Voits successfully tricked IT staff at Washtenaw County Jail into visiting a phony website at "ewashtenavv.org," which mimics the official URL, "ewashtenaw.org." The malicious website then installed malware on the IT

Earlier this month, Oracle patched a highly critical Java deserialization remote code execution vulnerability in its WebLogic Server component of Fusion Middleware that could allow attackers to easily gain complete control of a vulnerable server. However, a security researcher, who operates through the Twitter handle @pyn3rd and claims to be part of the Alibaba security team, has now found a way using which attackers can bypass the security patch and exploit the WebLogic vulnerability once again. WebLogic Server acts as a middle layer between the front end user interface and the backend database of a multi-tier enterprise application. It provides a complete set of services for all components and handles details of the application behavior automatically. Initially discovered in November last year by Liao Xinxi of NSFOCUS security team, the Oracle WebLogic Server flaw (CVE-2018-2628) can be exploited with network access over TCP port 7001. If exploited successfully, the fl

Damn! You have to update your Drupal websites. Yes, of course once again—literally it's the third time in last 30 days. As notified in advance two days back, Drupal has now released new versions of its software to patch yet another critical remote code execution (RCE) vulnerability, affecting its Drupal 7 and 8 core. Drupal is a popular open-source content management system software that powers millions of websites, and unfortunately, the CMS has been under active attacks since after the disclosure of a highly critical remote code execution vulnerability. The new vulnerability was discovered while exploring the previously disclosed RCE vulnerability, dubbed Drupalgeddon2 (CVE-2018-7600) that was patched on March 28, forcing the Drupal team to release this follow-up patch update. According to a new advisory released by the team, the new remote code execution vulnerability (CVE-2018-7602) could also allow attackers to take over vulnerable websites completely. How to Pa

In a major hit against international cybercriminals, the Dutch police have taken down the world's biggest DDoS-for-hire service that helped cyber criminals launch over 4 million attacks and arrested its administrators. An operation led by the UK's National Crime Agency (NCA) and the Dutch Police, dubbed " Power Off, " with the support of Europol and a dozen other law enforcement agencies, resulted in the arrest of 6 members of the group behind the " webstresser.org " website in Scotland, Croatia, Canada and Serbia on Tuesday. With over 136,000 registered users, Webstresser website lets its customers rent the service for about £10 to launch Distributed Denial of Service (DDoS) attacks against their targets with little or no technical knowledge. "With webstresser.org, any registered user could pay a nominal fee using online payment systems or cryptocurrencies to rent out the use of stressers and booters," Europol said. The service was also

Security researchers have uncovered a new hacking group that is aggressively targeting healthcare organizations and related sectors across the globe to conduct corporate espionage. Dubbed " Orangeworm ," the hacking group has been found installing a wormable trojan on machines hosting software used for controlling high-tech imaging devices, such as X-Ray and MRI machines, as well as machines used to assist patients in completing consent forms. According to a new report  published by Symantec on Monday, the Orangeworm hacking group has been active since early 2015 and targeting systems of major international corporations based in the United States, Europe, and Asia with a primary focus on the healthcare sector. "We believe that these industries have also been targeted as part of a larger supply-chain attack in order for Orangeworm to get access to their intended victims related to healthcare," Symantec said. After getting into the victim's network, atta

The British teenager who managed to hack into the online accounts of several high-profile US government employees sentenced to two years in prison on Friday. Kane Gamble , now 18, hacked into email accounts of former CIA director  John Brennan , former Director of National Intelligence James Clapper , former FBI Deputy Director Mark Giuliano , and other senior FBI officials—all from his parent's home in Leicestershire. Gamble, who went by the online alias Cracka, was just 15 at the time of carrying out those attacks and was the alleged founder of a hacking group calling themselves Crackas With Attitude (CWA). The notorious pro-Palestinian hacking group carried out a series of embarrassing attacks against U.S. intelligence officials and leaked personal details of 20,000 FBI agents , 9,000 officers from Department of Homeland Security, and some number of DoJ staffers in 2015. The teenager was arrested in February 2016 at his home in Coalville and pleaded guilty to 8 charg

The Drupal vulnerability (CVE-2018-7600), dubbed Drupalgeddon2 that could allow attackers to completely take over vulnerable websites has now been exploited in the wild to deliver malware backdoors and cryptocurrency miners. Drupalgeddon2, a highly critical remote code execution vulnerability discovered two weeks ago in Drupal content management system software, was recently patched by the company without releasing its technical details. However, just a day after security researchers at Check Point and Dofinity published complete details, a Drupalgeddon2 proof-of-concept (PoC) exploit code was made widely available, and large-scale Internet scanning and exploitation attempts followed. At the time, no incident of targets being hacked was reported, but over the weekend, several security firms noticed that attackers have now started exploiting the vulnerability to install cryptocurrency miner and other malware on vulnerable websites. The SANS Internet Storm Center spotted so

Last year, the popular system cleanup software CCleaner suffered a massive supply-chain malware attack of all times, wherein hackers compromised the company's servers for more than a month and replaced the original version of the software with the malicious one. The malware attack infected over 2.3 million users who downloaded or updated their CCleaner app between August and September last year from the official website with the backdoored version of the software. Now, it turns out that the hackers managed to infiltrate the company's network almost five months before they first replaced the official CCleaner build with the backdoored version, revealed Avast executive VP and CTO Ondrej Vlcek at the RSA security conference in San Francisco on Tuesday. 6-Months Timeline of CCleaner Supply Chain Attack Vlcek shared a brief timeline of the last year's incident that came out to be the worst nightmare for the company, detailing how and when unknown hackers breached Pi

Security researchers have been warning about an ongoing malware campaign hijacking Internet routers to distribute Android banking malware that steals users' sensitive information, login credentials and the secret code for two-factor authentication. In order to trick victims into installing the Android malware, dubbed Roaming Mantis , hackers have been hijacking DNS settings on vulnerable and poorly secured routers . DNS hijacking attack allows hackers to intercept traffic, inject rogue ads on web-pages and redirect users to phishing pages designed to trick them into sharing their sensitive information like login credentials, bank account details, and more. Hijacking routers' DNS for a malicious purpose is not new. Previously we reported about widespread DNSChanger and Switcher —both the malware worked by changing the DNS settings of the wireless routers to redirect traffic to malicious websites controlled by attackers. Discovered by security researchers at Kaspersk

Internet-connected technology, also known as the Internet of Things (IoT), is now part of daily life, with smart assistants like Siri and Alexa to cars, watches, toasters, fridges, thermostats, lights, and the list goes on and on. But of much greater concern, enterprises are unable to secure each and every device on their network, giving cybercriminals hold on their network hostage with just one insecure device. Since IoT is a double-edged sword, it not only poses huge risks to enterprises worldwide but also has the potential to severely disrupt other organisations, or the Internet itself . There's no better example than Mirai , the botnet malware that knocked the world's biggest and most popular websites offline for few hours over a year ago. We have another great example that showcases how one innocent looking insecure IoT device connected to your network can cause security nightmares. Nicole Eagan, the CEO of cybersecurity company Darktrace, told attendees at

Android ecosystem is highly broken when it comes to security, and device manufacturers (better known as OEMs) make it even worse by not providing critical patches in time. According to a new study, most Android vendors have been lying to users about security updates and telling customers that their smartphones are running the latest updates. In other words, most smartphone manufacturers including big players like Samsung, Xiaomi, OnePlus, Sony, HTC, LG, and Huawei are not delivering you every critical security patch they're supposed to, a study by Karsten Nohl and Jakob Lell of German security firm Security Research Labs (SRL) revealed. Nohl and Lell examined the firmware of 1,200 smartphones from over a dozen vendors, for every Android patch released last year, and found that many devices have a "patch gap," leaving parts of the Android ecosystem exposed to hackers. "Sometimes these guys just change the date without installing any patches. Probably for m

A serious vulnerability has been exposed in "emergency alert systems" that could be exploited remotely via radio frequencies to activate all the sirens, allowing hackers to trigger false alarms. The emergency alert sirens are used worldwide to alert citizens about natural disasters, man-made disasters, and emergency situations, such as dangerous weather conditions, severe storms, tornadoes and terrorist attacks. False alarms can create panic and chaos across the city, as witnessed in Dallas last year , when 156 emergency sirens were turned on for about two hours, waking up residents and sparking fears of a disaster. Dubbed " SirenJack Attack ," the vulnerability discovered by a researcher at Bastille security firm affects warning sirens manufactured by Boston-based ATI Systems, which are being used across major towns and cities, as well as Universities, military facilities, and industrial sites. According to Balint Seeber, director of threat research at

Since last week, a new hacking group, calling itself ' JHT ,' hijacked a significant number of Cisco devices belonging to organizations in Russia and Iran, and left a message that reads—" Do not mess with our elections " with an American flag (in ASCII art). MJ Azari Jahromi, Iranian Communication and Information Technology Minister, said the campaign impacted approximately 3,500 network switches in Iran, though a majority of them were already restored. The hacking group is reportedly targeting vulnerable installations of Cisco Smart Install Client, a legacy plug-and-play utility designed to help administrators configure and deploy Cisco equipments remotely, which is enabled by default on Cisco IOS and IOS XE switches and runs over TCP port 4786. Some researchers believe the attack involves a recently disclosed remote code execution vulnerability ( CVE-2018-0171 ) in Cisco Smart Install Client that could allow attackers to take full control of the network

Over 130,000 Finnish citizens have had their credentials compromised in what appears to be third largest data breach ever faced by the country, local media reports . Finnish Communications Regulatory Authority (FICORA) is warning users of a large-scale data breach in a website maintained by the New Business Center in Helsinki ("Helsingin Uusyrityskeskus"), a company that provides business advice to entrepreneurs and help them create right business plans. Unknown attackers managed to hack the website ( https://liiketoimintasuunnitelma.com ) and stole over 130,000 users' login usernames and passwords, which were stored on the site in plain-text without using any cryptographic hash. Right after knowing of the breach on 3rd April, the company took down the affected website, which is currently showing "under maintenance" notice with a press release about the incident on its homepage. "We are very sorry for all the people who have been subjected to crime a
