Services offered by an obscure Iranian company known as Cloudzy are being leveraged by multiple threat actors, including cybercrime groups and nation-state crews. "Although Cloudzy is incorporated in the United States, it almost certainly operates out of Tehran, Iran – in possible violation of U.S. sanctions – under the direction of someone going by the name  Hassan Nozari ," Halcyon  said  in a new report published Tuesday. The Texas-based cybersecurity firm said the company acts as a command-and-control provider (C2P), which provides attackers with Remote Desktop Protocol (RDP) virtual private servers and other anonymized services that ransomware affiliates and others use to pull off the cybercriminal endeavors. "[C2Ps] enjoy a liability loophole that does not require them to ensure that the infrastructure they provide is not being used for illegal operations," Halcyon said in a statement shared with The Hacker News. The ransomware-as-a-service (RaaS) busine

If it seems like Remote Desktop Protocol (RDP) has been around forever, it's because it has (at least compared to the many technologies that rise and fall within just a few years.) The initial version, known as "Remote Desktop Protocol 4.0," was released in 1996 as part of the Windows NT 4.0 Terminal Server edition and allowed users to remotely access and control Windows-based computers over a network connection.  In the intervening decades, RDP has become a widely used protocol for remote access and administration of Windows-based systems. RDP plays a crucial role in enabling remote work, IT support, and system management and has served as the foundation for various remote desktop and virtual desktop infrastructure (VDI) solutions.  The downside of RDP's widespread use is that a Remote Code Execution (RCE) vulnerability in an RDP gateway can have severe consequences, potentially leading to significant damage and compromising the security and integrity of the affec

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

Microsoft is now taking steps to prevent Remote Desktop Protocol (RDP) brute-force attacks as part of the latest builds for the Windows 11 operating system in an attempt to raise the  security baseline  to meet the evolving threat landscape. To that end, the default policy for Windows 11 builds – particularly, Insider Preview builds 22528.1000 and newer – will automatically lock accounts for 10 minutes after 10 invalid sign-in attempts. "Win11 builds now have a DEFAULT account lockout policy to mitigate RDP and other brute-force password vectors," David Weston, Microsoft's vice president for OS security and enterprise,  said  in a series of tweets last week. "This technique is very commonly used in Human Operated Ransomware and other attacks -- this control will make brute forcing much harder which is awesome!" It's worth pointing out that while this  account lockout setting  is already incorporated in Windows 10, it's not enabled by default. The f

A new research has uncovered multiple critical reverse RDP vulnerabilities in Apache Guacamole , a popular remote desktop application used by system administrators to access and manage Windows and Linux machines remotely. The reported flaws could potentially let bad actors achieve full control over the Guacamole server, intercept, and control all other connected sessions. According to a report published by Check Point Research and shared with The Hacker News, the flaws grant "an attacker, who has already successfully compromised a computer inside the organization, to launch an attack on the Guacamole gateway when an unsuspecting worker tries to connect to an infected machine." After the cybersecurity firm responsibly disclosed its findings to Apache, the maintainers of Guacamole, on March 31, the company released a patched version in June 2020. Apache Guacamole is a popular open-source clientless remote desktop gateways solution. When installed on a company'

Remember the Reverse RDP Attack —wherein a client system vulnerable to a path traversal vulnerability could get compromised when remotely accessing a server over Microsoft's Remote Desktop Protocol? Though Microsoft had patched the vulnerability (CVE-2019-0887) as part of its July 2019 Patch Tuesday update, it turns out researchers were able to bypass the patch just by replacing the backward slashes in paths with forward slashes. Microsoft acknowledged the improper fix and re-patched the flaw in its February 2020 Patch Tuesday update earlier this year, now tracked as CVE-2020-0655. In the latest report shared with The Hacker News, Check Point researcher disclosed that Microsoft addressed the issue by adding a separate workaround in Windows while leaving the root of the bypass issue, an API function "PathCchCanonicalize," unchanged. Apparently, the workaround works fine for the built-in RDP client in Windows operating systems, but the patch is not fool-proof en

If you are using any supported version of the Windows operating system, stop everything and install the latest security updates from Microsoft immediately. Windows operating system contains four new critical wormable, remote code execution vulnerabilities in Remote Desktop Services, similar to the recently patched ' BlueKeep ' RDP vulnerability. Discovered by Microsoft's security team itself, all four vulnerabilities, CVE-2019-1181 , CVE-2019-1182 , CVE-2019-1222 , and CVE-2019-1226 , can be exploited by unauthenticated, remote attackers to take control of an affected computer system without requiring any user interaction. Just like BlueKeep RDP flaw , all four newly discovered vulnerabilities are also wormable and could be exploited by potential malware to propagate itself from one vulnerable computer to another automatically. "An attacker can get code execution at the system level by sending a specially crafted pre-authentication RDP packet to an affected RD

You have always been warned not to share remote access to your computer with untrusted people for any reason—it's a basic cybersecurity advice, and common sense, right? But what if, I say you should not even trust anyone who invites or offer you full remote access to their computers. A critical vulnerability has been discovered in Microsoft's Windows Remote Assistanc e (Quick Assist) feature that affects all versions of Windows to date, including Windows 10, 8.1, RT 8.1, and 7, and allows remote attackers to steal sensitive files on the targeted machine. Windows Remote Assistance is a built-in tool that allows someone you trust to take over your PC (or you to take remote control of others) so they can help you fix a problem from anywhere around the world. The feature relies on the Remote Desktop Protocol (RDP) to establish a secure connection with the person in need. However, Nabeel Ahmed of Trend Micro Zero Day Initiative discovered and reported an information di

Do you have remote login software TeamViewer installed on your desktop? If Yes, then it could be possible that your system can be accessed by attackers to steal your personal details, including your bank and PayPal accounts, as several reports on Reddit and Twitter suggests. According to recent reports, the popular TeamViewer software that is used to remotely control PCs appears to have been HACKED ! Over the past few days, a number of users headed on to the Internet forums to report that unknown attackers are taking control of their computers through their TeamViewer accounts and, in some cases, trying to steal money through services like eBay or PayPal. This same behavior has also been reported by the IBM security researcher Nick Bradley, who said: "In the middle of my gaming session, I lose control of my mouse, and the TeamViewer window pops up in the bottom right corner of my screen. As soon as I realize what is happening, I kill the application. Then it dawns

Security researchers have developed a more practical and feasible attack technique against the RC4 cryptographic algorithm that is still widely used to encrypt communications on the Internet. Despite being very old, RC4 (Rivest Cipher 4) is still the most widely used cryptographic cipher implemented in many popular protocols, including: SSL (Secure Socket Layer) TLS (Transport Layer Security) WEP (Wired Equivalent Privacy) WPA (Wi-Fi Protected Access) Microsoft's RDP (Remote Desktop Protocol) BitTorrent and many more However, weaknesses in the algorithm have been found over the years, indicating that the RC4 needs to be wiped from the Internet. But, yet about 50% of all TLS traffic is currently protected using the RC4 encryption algorithm. Now, the situation got even worse, when two Belgian security researchers demonstrated a more practical attack against RC4, allowing an attacker to subsequently expose encrypted information in a much shorter amount of time t

We have already seen vulnerability in Remote Desktop Protocol (RDP) is a potential dangers of desktop remote-access tools commonly used by IT departments to handle help-desk issues and by administrators to manage virtualized machines. According to reports from krebsonsecurity, A Russian company called " dedicated express " ( Dedicatexpress.com ) is selling access to private company servers for as little as $4. Cyber criminals have hacked around 17,000 computers worldwide using such insecure applications in server and selling them in underground markets. Although almost 300,000 compromised systems have passed through this service since its inception in early 2010. New customers who contact the service's owner via instant message and pay a $20 registration fee via WebMoney, a virtual currency. The price of any hacked server is calculated based on several qualities, including the speed of its processor and the number of processor cores, the machine's download and up
