Google researcher has discovered a severe vulnerability in modern web browsers that could have allowed websites you visit to steal the sensitive content of your online accounts from other websites that you have logged-in the same browser. Discovered by Jake Archibald, developer advocate for Google Chrome, the vulnerability resides in the way browsers handle cross-origin requests to video and audio files, which if exploited, could allow remote attackers to even read the content of your Gmail or private Facebook messages. For security reasons, modern web browsers don't allow websites to make cross-origin requests to a different domain unless any domain explicitly allows it. That means, if you visit a website on your browser, it can only request data from the same origin the site was loaded from, preventing it from making any unauthorized request on your behalf in an attempt to steal your data from other sites. However, web browsers do not respond in the same way while fetc...

One of the world's most popular flight tracking services Flightradar24 , which shows real-time aircraft flight information on a map, has suffered a massive data breach that may have compromised email addresses and hashed passwords for more than 230,000 customers. Without revealing any information about the breach publically via their blog or social media accounts, Flightradar24 started sending out emails earlier this week with a password reset link, asking them to change their passwords. The incomplete reference to suddenly announced data breach incident via emails and providing a unique password reset link to each user caused some customers to suspect that they have been a target of a phishing attack. However, later the company confirmed the breach while responding to its customers' queries on the official forum and Twitter , saying that the breach notifications they have received via emails are legitimate and that neither payment nor personal information has been compr...

Security-oriented BSD operating system OpenBSD has decided to disable support for Intel's hyper-threading performance-boosting feature, citing security concerns over Spectre-style timing attacks . Introduced in 2002, Hyper-threading is Intel's implementation of Simultaneous Multi-Threading (SMT) that allows the operating system to use a virtual core for each physical core present in processors in order to improve performance. The Hyper-threading feature comes enabled on computers by default for performance boosting, but in a detailed post published Tuesday, OpenBSD maintainer Mark Kettenis said such processor implementations could lead to Spectre-style timing attacks. "SMT (Simultaneous multithreading) implementations typically share TLBs and L1 caches between threads," Kettenis wrote. "This can make cache timing attacks a lot easier, and we strongly suspect that this will make several Spectre-class bugs exploitable." In cryptography, side-channe...

Security researchers have been warning of a new trick that cybercriminals are leveraging to hide their malicious code designed to re-introduce the infection to steal confidential information from Magento based online e-commerce websites. So, if you have already cleaned up your hacked Magento website, there are chances your website is still leaking login credentials and credit card details of your customers to hackers. More than 250,000 online stores use open-source Magento e-commerce platform, which makes them an enticing target for hackers, and therefore the security of both your data and your customer data is of the utmost importance. According to the researchers at Sucuri , who have previously spotted several Magento malware campaigns in the wild, cybercriminals are currently using a simple yet effective method to ensure that their malicious code is added back to a hacked website after it has been removed. To achieve this, criminals are hiding their 'credit card stea...

Security researchers have been warning about a simple technique that cyber criminals and email scammers are using in the wild to bypass most AI-powered phishing detection mechanisms implemented by widely used email services and web security scanners. Dubbed ZeroFont , the technique involves inserting hidden words with a font size of zero within the actual content of a phishing email, keeping its visual appearance same, but at the same time, making it non-malicious in the eyes of email security scanners. According to cloud security company Avanan , Microsoft Office 365 also fails to detect such emails as malicious crafted using ZeroFont technique. Like Microsoft Office 365, many emails and web security services use natural language processing and other artificial intelligence-based machine learning techniques to identify malicious or phishing emails faster. The technology helps security companies to analyze, understand and derive meaning from unstructured text embedded in an...

Remember the ' Olympic Destroyer ' cyber attack? The group behind it is still alive, kicking and has now been found targeting biological and chemical threat prevention laboratories in Europe and Ukraine, and a few financial organisation in Russia. Earlier this year, an unknown group of notorious hackers targeted Winter Olympic Games 2018 , held in South Korea, using a destructive malware that purposely planted sophisticated false flags to trick researchers into mis-attributing the campaign. Unfortunately, the destructive malware was successful to some extent, at least for a next few days, as immediately after the attack various security researchers postmortem the Olympic Destroyer malware and started attributing the attack to different nation-state hacking groups from North Korea, Russia, and China. Later researchers from Russian antivirus vendor Kaspersky Labs uncovered more details about the attack, including the evidence of false attribution artifacts, and conclud...

BitTorrent, the company which owns the popular file-sharing client uTorrent, has quietly been sold for $140 million in cash to Justin Sun, the founder of blockchain-focused startup TRON. TRON is a decentralized entertainment and content-sharing platform that uses blockchain and distributed storage technology. It allows users to publish content without having to use third-party platforms such as YouTube or Facebook, and trades in Tronix (TRX) cryptocurrency. Since BitTorrent is one of the most recognizable brands in the world for decentralized computing and peer-to-peer (P2P) networking, and TRON aims to establish a truly decentralized Internet, BitTorrent would be of great use for Sun to help achieve that goal. There were reports that the two were in negotiations for at least a month, and just yesterday, Variety reported that BitTorrent Inc. was sold to Sun last week, but the report did not disclose the deal price. Now, TechCrunch is reporting that TRON's founder has ...

A 29-year-old former CIA computer programmer who was charged with possession of child pornography last year has now been charged with masterminding the largest leak of classified information in the agency's history. Joshua Adam Schulte , who once created malware for both the CIA and NSA to break into adversaries computers, was indicted Monday by the Department of Justice on 13 charges of allegedly stealing and transmitting thousands of classified CIA documents , software projects , and hacking utilities . Schulte has also been suspected of leaking the stolen archive of documents to anti-secrecy organization WikiLeaks, who then began publishing the classified information in March 2017 in a series of leaks under the name " Vault 7 ." It is yet unconfirmed whether Schulte leaked documents to WikiLeaks and if yes, then when, but he had already been a suspect since January 2017 of stealing classified national defense information from the CIA in 2016. According to ...

Security researchers are warning of almost a decade old issue with one of the Apple's macOS feature which was designed for users' convenience but is potentially exposing the contents of files stored on password-protected encrypted drives. Earlier this month, security researcher Wojciech Regula from SecuRing published a blog post , about the "Quick Look" feature in macOS that helps users preview photos, documents files, or a folder without opening them. Regula explained that Quick Look feature generates thumbnails for each file/folder, giving users a convenient way to evaluate files before they open them. However, these cached thumbnails are stored on the computer's non-encrypted hard drive, at a known and unprotected location, even if those files/folders belong to an encrypted container, eventually revealing some of the content stored on encrypted drives. Patrick Wardle, chief research officer at Digital Security, equally shared the concern, saying tha...

A security researcher has discovered a critical vulnerability in some of the world's most popular and widely used email encryption clients that use OpenPGP standard and rely on GnuPG for encrypting and digitally signing messages. The disclosure comes almost a month after researchers revealed a series of flaws, dubbed eFail , in PGP and S/Mime encryption tools that could allow attackers to reveal encrypted emails in plaintext , affecting a variety of email programs, including Thunderbird, Apple Mail, and Outlook. Software developer Marcus Brinkmann discovered that an input sanitization vulnerability, which he dubbed SigSpoof , makes it possible for attackers to fake digital signatures with someone's public key or key ID, without requiring any of the private or public keys involved. The vulnerability, tracked as CVE-2018-12020 , affects popular email applications including GnuPG, Enigmail, GPGTools and python-gnupg, and have now been patched in their latest available so...

Cybersecurity researchers have uncovered an espionage campaign that has targeted a national data center of an unnamed central Asian country in order to conduct watering hole attacks. The campaign is believed to be active covertly since fall 2017 but was spotted in March by security researchers from Kaspersky Labs, who have attributed these attacks to a Chinese-speaking threat actor group called LuckyMouse . LuckyMouse, also known as Iron Tiger, EmissaryPanda, APT 27 and Threat Group-3390, is the same group of Chinese hackers who was found targeting Asian countries with Bitcoin mining malware early this year. The group has been active since at least 2010 and was behind many previous attack campaigns resulting in the theft of massive amounts of data from the directors and managers of US-based defense contractors. This time the group chose a national data center as its target from an unnamed country in Central Asia in an attempt to gain "access to a wide range of government ...
