A new social engineering-based malvertising campaign targeting Japan has been found to deliver a malicious application that deploys a banking trojan on compromised Windows machines to steal credentials associated with cryptocurrency accounts. The application masquerades as an animated porn game, a reward points application, or a video streaming application, Trend Micro researchers Jaromir Horejsi and Joseph C Chen  said  in an analysis published last week, attributing the operation to a threat actor it tracks as Water Kappa, which was  previously found  targeting Japanese online banking users with the Cinobi trojan by leveraging exploits in Internet Explorer browser. The switch in tactics is an indicator that the adversary is singling out users of web browsers other than Internet Explorer, the researchers added. Water Kappa's latest infection routine commences with malvertisements for either Japanese animated porn games, reward points apps, or video streaming s...

The Incident Response (IR) services market is in accelerated growth due to the rise in cyberattacks that result in breaches. More and more organizations, across all sizes and verticals, choose to outsource IR to 3rd party service providers over handling security incidents in-house. Cynet is now launching a first-of-its-kind offering, enabling any Managed Security Provider (MSP) or Security Integrator (SI) to add Incident Response to its services portfolio, without building an in-house team of incident responders, by using Cynet's IR team and technology at no cost. Managed Service providers interested to add Incident Response to their service portfolio with no investment in people or technology can apply here . As cyber threats grow in sophistication and volume, there is an increasing number of cases in which attackers succeed in compromising the environments they target. This, in turn, fuels a rapidly growing demand for IR technologies and services. Since in most cases ...

Taiwanese chip designer Realtek is warning of  four security vulnerabilities  in three software development kits (SDKs) accompanying its WiFi modules, which are used in almost 200 IoT devices made by at least 65 vendors. The flaws, which affect Realtek SDK v2.x, Realtek "Jungle" SDK v3.0/v3.1/v3.2/v3.4.x/v3.4T/v3.4T-CT, and Realtek "Luna" SDK up to version 1.3.2, could be abused by attackers to fully compromise the target device and execute arbitrary code with the highest level of privilege — CVE-2021-35392  (CVSS score: 8.1) - Heap buffer overflow vulnerability in 'WiFi Simple Config' server due to unsafe crafting of SSDP NOTIFY messages CVE-2021-35393  (CVSS score: 8.1) - Stack buffer overflow vulnerability in 'WiFi Simple Config' server due to unsafe parsing of the UPnP SUBSCRIBE/UNSUBSCRIBE Callback header CVE-2021-35394  (CVSS score: 9.8) - Multiple buffer overflow vulnerabilities and an arbitrary command injection vulnerability in 'UD...

Weaknesses in the implementation of TCP protocol in  middleboxes  and censorship infrastructure could be weaponized as a vector to stage reflected denial of service (DoS) amplification attacks against any target, surpassing many of the existing UDP-based amplification factors to date. Detailed by a group of academics from the University of Maryland and the University of Colorado Boulder at the USENIX Security Symposium, the volumetric attacks take advantage of TCP-non-compliance in-network middleboxes — such as firewalls, intrusion prevention systems, and deep packet inspection (DPI) boxes — to amplify network traffic, with hundreds of thousands of IP addresses offering  amplification factors  exceeding those from DNS, NTP, and Memcached. The research, which received a Distinguished Paper Award at the conference, is the first of its kind to describe a technique to carry out DDoS reflected amplification attacks over the TCP protocol by abusing middlebox misconfigu...

Security researchers have disclosed as many as 40 different vulnerabilities associated with an opportunistic encryption mechanism in mail clients and servers that could open the door to targeted man-in-the-middle (MitM) attacks, permitting an intruder to forge mailbox content and steal credentials. The now-patched flaws, identified in various STARTTLS implementations, were  detailed  by a group of researchers Damian Poddebniak, Fabian Ising, Hanno Böck, and Sebastian Schinzel at the 30th USENIX Security Symposium. In an Internet-wide scan conducted during the study, 320,000 email servers were found vulnerable to what's called a command injection attack. Some of the popular clients affected by the bugs include Apple Mail, Gmail, Mozilla Thunderbird, Claws Mail, Mutt, Evolution, Exim, Mail.ru, Samsung Email, Yandex, and KMail. The attacks require that the malicious party can tamper connections established between an email client and the email server of a provider and has log...

A new wave of attacks involving a notorious macOS adware family has evolved to leverage around 150 unique samples in the wild in 2021 alone, some of which have slipped past Apple's on-device malware scanner and even signed by its own notarization service, highlighting the malicious software ongoing attempts to adapt and evade detection. "AdLoad," as the malware is known, is one of several widespread adware and bundleware loaders targeting macOS since at least 2017. It's capable of backdooring an affected system to download and install adware or potentially unwanted programs (PUPs), as well as amass and transmit information about victim machines. The new iteration "continues to impact Mac users who rely solely on Apple's built-in security control XProtect for malware detection," SentinelOne threat researcher Phil Stokes  said  in an analysis published last week. "As of today, however, XProtect arguably has around 11 different signatures for AdLoa...

A novel technique leverages optical emanations from a device's power indicator LED to recover sounds from connected peripherals and spy on electronic conversations from a distance of as much as 35 meters. Dubbed the " Glowworm attack ," the findings were published by a group of academics from the Ben-Gurion University of the Negev earlier this week, describing the method as "an optical  TEMPEST  attack that can be used by eavesdroppers to recover sound by analysing optical measurements obtained via an electro-optical sensor directed at the power indicator LED of various devices." Accompanying the experimental setup is an optical-audio transformation (OAT) that allows for retrieving sound by isolating the speech from the optical measurements obtained by directing an electro-optical sensor at the device's power indicator LED. TEMPEST is the codename for unintentional intelligence-bearing emanations produced by electronic and electromechanical information-...

If you're reading this post, there is a pretty good chance you're interested in hacking. Ever thought about turning it into a career? The cybersecurity industry is booming right now, and ethical hacking is one of the most lucrative and challenging niches. It's open to anyone with the right skills. Featuring 18 courses from top-rated instructors,  The All-In-One 2021 Super-Sized Ethical Hacking Bundle  helps you acquire those skills.  If you went on a shopping spree, these courses would normally set you back $3,284 in total.  However, The Hacker News has teamed up with several education partners to offer  the full bundle for just $42.99 . That means you're paying less than $3 per course! Ethical hacking is all about finding the weaknesses in systems before they can be exploited by malicious hackers. Many people who work in this field earn six figures, and top experts often work for themselves. There are two things you need for building a career in ethical...

Facebook on Friday said it's extending end-to-end encryption (E2EE) for voice and video calls in Messenger, along with testing a new opt-in setting that will turn on end-to-end encryption for Instagram DMs. "The content of your messages and calls in an end-to-end encrypted conversation is protected from the moment it leaves your device to the moment it reaches the receiver's device," Messenger's Ruth Kricheli  said  in a post. "This means that nobody else, including Facebook, can see or listen to what's sent or said. Keep in mind, you can report an end-to-end encrypted message to us if something's wrong." The social media behemoth said E2EE is becoming the industry standard for improved privacy and security. It's worth noting that the company's flagship messaging service gained support for E2EE in text chats in 2016, when it added a " secret conversation " option to its app, while communications on its sister platform What...
