Security researchers have discovered a new class of security vulnerabilities that impacts all major operating systems, including Microsoft Windows, Apple macOS, Linux, and FreeBSD, allowing attackers to bypass protection mechanisms introduced to defend against DMA attacks. Known for years, Direct memory access (DMA)-based attacks let an attacker compromise a targeted computer in a matter of seconds by plugging-in a malicious hot plug device—such as an external network card, mouse, keyboard, printer, storage, and graphics card—into Thunderbolt 3 port or the latest USB-C port . The DMA-based attacks are possible because Thunderbolt port allows connected peripherals to bypass operating system security policies and directly read/write system memory that contains sensitive information including your passwords, banking logins, private files, and browser activity. That means, simply plugging in an infected device, created using tools like Interception , can manipulate the contents o...

It's not just the critical Drupal vulnerability that is being exploited by in the wild  cybercriminals to attack vulnerable websites that have not yet applied patches already available by its developers, but hackers are also exploiting a critical WinRAR vulnerability that was also revealed last week. A few days ago, The Hacker News reported about a 19-year-old remote code execution vulnerability disclosed by Check Point in the UNACEV2.dll library of WinRAR that could allow a maliciously-crafted ACE archive file to execute arbitrary code on a targeted system. WinRAR is a popular Windows file compression application with 500 million users worldwide, but a critical "Absolute Path Traversal" bug (CVE-2018-20250) in its old third-party library, called UNACEV2.DLL, could allow attackers to extract a compressed executable file from the ACE archive to one of the Windows Startup folders, where the file would automatically run on the next reboot. To successfully exploit the...

Cybercriminals have actively started exploiting an already patched security vulnerability in the wild to install cryptocurrency miners on vulnerable Drupal websites that have not yet applied patches and are still vulnerable. Last week, developers of the popular open-source content management system Drupal patched a critical remote code execution (RCE) vulnerability (CVE-2019-6340) in Drupal Core that could allow attackers to hack affected websites. Despite releasing no technical details of the security vulnerability, the proof-of-concept (PoC) exploit code for the vulnerability was made publicly available on the Internet just two days after the Drupal security team rolled out the patched version of its software. Now, security researchers at data center security vendor Imperva discovered a series of attacks—that began just a day after the exploit code went public—against its customers' websites using an exploit that leverages the CVE-2019-6340 security flaw. The attacks or...

Great news. If you have already installed the latest update of Google Play Services released earlier today, and your Android device is running Android version 7.0 Nougat or above—Congratulations! Your device is now FIDO2 Certified. Are you thinking… what the heck that actually means? It means, instead of remembering complex passwords for your online accounts, you can now actually use your Android's built-in fingerprint sensor or FIDO security keys for secure password-less access to log into apps and websites that support the FIDO2 protocols, Google and the FIDO Alliance—a consortium that develops open source authentication standards—announced Monday. FIDO2 (Fast Identity Online) protocol offers strong passwordless authentication based on standard public key cryptography using hardware FIDO authenticators like security keys, mobile phones, and other built-in devices. FIDO2 protocol is a combination of W3C's WebAuthn API that allows developers to integrate FIDO aut...

At NDSS Symposium 2019, a group of university researchers yesterday revealed newly discovered cellular network vulnerabilities that impact both 4G and 5G LTE protocols. According to a paper published by the researchers, " Privacy Attacks to the 4G and 5G Cellular Paging Protocols Using Side Channel Information, " the new attacks could allow remote attackers to bypass security protections implemented in 4G and 5G, re-enabling IMSI catching devices like " Stingrays " to intercept users' phone calls and track their location. Here below, we have described all the three attacks, how they work, what are their impacts, and why you should be concerned about these attacks. ToRPEDO Attack — Location Verification, DoS, Inject Fake Alerts Short for "TRacking via Paging mEssage DistributiOn," TorPEDO is the most concerning attack that leverages paging protocol, allowing remote attackers to verify a victim device's location, inject fabricated paging mess...
