Academic researchers today disclosed details of the newest class of speculative execution side-channel vulnerabilities in Intel processors that impacts all modern chips, including the chips used in Apple devices. After the discovery of Spectre and Meltdown processor vulnerabilities earlier last year that put practically every computer in the world at risk, different classes of Spectre and Meltdown variations surfaced again and again. Now, a team of security researchers from multiple universities and security firms has discovered different but more dangerous speculative execution side-channel vulnerabilities in Intel CPUs. The newly discovered flaws could allow attackers to directly steal user-level, as well as system-level secrets from CPU buffers, including user keys, passwords, and disk encryption keys. Speculative execution is a core component of modern processors design that speculatively executes instructions based on assumptions that are considered likely to be true.

It's Patch Tuesday—the day when Microsoft releases monthly security updates for its software. Microsoft has software updates to address a total of 79 CVE-listed vulnerabilities in its Windows operating systems and other products, including a critical wormable flaw that can propagate malware from computer to computer without requiring users' interaction. Out of 79 vulnerabilities, 18 issues have been rated as critical and rest Important in severity. Two of the vulnerabilities addressed this month by the tech giant are listed as publicly known, of which one is listed as under active attack at the time of release. May 2019 security updates address flaws in Windows OS, Internet Explorer, Edge, Microsoft Office, and Microsoft Office Services and Web Apps, ChakraCore, .NET Framework, and ASP.NET, Skype for Android, Azure DevOps Server, and the NuGet Package Manager. Critical Wormable RDP Vulnerability The wormable vulnerability ( CVE-2019-0708 ) resides in Remote Desktop

Follow this real-life network attack simulation, covering 6 steps from Initial Access to Data Exfiltration. See how attackers remain undetected with the simplest tools and why you need multiple choke points in your defense strategy. Surprisingly, most network attacks are not exceptionally sophisticated, technologically advanced, or reliant on zero-day tools that exploit edge-case vulnerabilities. Instead, they often use commonly available tools and exploit multiple vulnerability points. By simulating a real-world network attack, security teams can test their detection systems, ensure they have multiple choke points in place, and demonstrate the value of networking security to leadership. In this article, we demonstrate a real-life attack that could easily occur in many systems. The attack simulation was developed based on the MITRE ATT&CK framework, Atomic Red Team,  Cato Networks ' experience in the field, and public threat intel. In the end, we explain why a holistic secur

Adobe today released its monthly software updates to patch a total of 87 security vulnerabilities in its Adobe Acrobat and Reader, Flash Player and Media Encoder, most of which could lead to arbitrary code execution attacks or worse. None of the flaws patched this month in Adobe products has been found exploited in the wild. Out of 87 total flaws, a whopping number of vulnerabilities (i.e., 84 in total) affect Adobe Acrobat and Reader applications alone, where 42 of them are critical and rest 42 are important in severity. Upon successful exploitation, all critical vulnerabilities in Adobe Acrobat and Reader software lead to arbitrary code execution, allowing attackers to take complete control over targeted systems. Adobe has released updated versions of Acrobat and Reader software for Windows and macOS operating systems to address these security vulnerabilities. The update for Adobe Flash Player , which will receive security patch updates until the end of 2020, comes this

Researchers have discovered a severe vulnerability in Cisco products that could allow attackers to implant persistent backdoor on wide range devices used in enterprises and government networks, including routers, switches, and firewalls. Dubbed Thrangrycat or 😾😾😾, the vulnerability, discovered by researchers from the security firm Red Balloon and identified as CVE-2019-1649, affects multiple Cisco products that support Trust Anchor module (TAm). Trust Anchor module (TAm) is a hardware-based Secure Boot functionality implemented in almost all of Cisco enterprise devices since 2013 that ensures the firmware running on hardware platforms is authentic and unmodified. However, researchers found a series of hardware design flaws that could allow an authenticated attacker to make the persistent modification to the Trust Anchor module via FPGA bitstream modification and load the malicious bootloader. "An attacker with root privileges on the device can modify the contents of

Though once synonymous with underground networks and black hat hackers, bitcoin and other cryptocurrencies have gone mainstream over the past two years. In 2017, we saw the skyrocket of bitcoin to an all-time high of close to $20,000 followed by a significant decline the following year. But beyond the ups and downs in the market for the world's largest cryptocurrency is a much more sinister story revolving around cyber-attacks of the economy's newest asset class. In 2018, it estimated that as much as $1.7 billion worth of cryptocurrencies were swindled away from investors (likely more) through a variety of means. Whether accomplished through hacking, phishing, or other forms of scamming, it's clear that the crypto industry is facing a serious dilemma with security. For a technological movement based on decentralization and the advantages it offers for security, the number of breaches occurring is startling. Cryptocurrencies offer users a way to send money with

Whatsapp has recently patched a severe vulnerability that was being exploited by attackers to remotely install surveillance malware on a few "selected" smartphones by simply calling the targeted phone numbers over Whatsapp audio call. Discovered, weaponized and then sold by the Israeli company NSO Group that produces the most advanced mobile spyware on the planet, the WhatsApp exploit installs Pegasus spyware on to Android and iOS devices. According to an advisory published by Facebook, a buffer overflow vulnerability in WhatsApp VOIP stack allows remote attackers to execute arbitrary code on target phones by sending a specially crafted series of SRTCP packets. Apparently, the vulnerability, identified as CVE-2019-3568 , can successfully be exploited to install the spyware and steal data from a targeted Android phone or iPhone by merely placing a WhatsApp call, even when the call is not answered. Also, the victim would not be able to find out about the intrusion af

The U.S. Department of Justice today announced charges against nine individuals, 6 of which are members of a hacking group called "The Community" and other 3 are former employees of mobile phone providers who allegedly helped them steal roughly $2.5 million worth of the cryptocurrency using a method known as "SIM Swapping." According to the 15-count indictment unsealed today, five Americans and an Irishman related to The Community hacking group are charged with conspiracy to commit wire fraud, as well as wire fraud and aggravated identity theft. Another three Americans, who reportedly are the former employees of mobile phone providers, are charged in a criminal complaint with the wire fraud. SIM Swapping , or SIM Hijacking , is a type of identity theft that typically involves fraudulently porting of the same number to a new SIM card belonging to the attacker. In SIM swapping, attackers social engineer a victim's mobile phone provider by convincing it
