RDP exploit | Breaking Cybersecurity News | The Hacker News

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

A new module for TrickBot banking Trojan has recently been discovered in the wild that lets attackers leverage compromised systems to launch brute-force attacks against selected Windows systems running a Remote Desktop Protocol (RDP) connection exposed to the Internet. The module, dubbed " rdpScanDll ," was discovered on January 30 and is said to be still in development, said cybersecurity firm Bitdefender in a report shared with The Hacker news. According to the researchers, the rdpScanDll brute-forcing module has so far attempted to target 6,013 RDP servers belonging to enterprises in telecom, education, and financial sectors in the U.S. and Hong Kong. The malware authors behind TrickBot specialize in releasing new modules and versions of the Trojan in an attempt to expand and refine its capabilities. "The flexibility allowed by this modular architecture has turned TrickBot into a very complex and sophisticated malware capable of a wide range of malicious a

Streamline your zero-trust access journey with three simple steps for high-risk, remote, and hybrid users.

You've always been warned not to share remote access to your computer with any untrusted people for many reasons—it's basic cyber security advice, and common sense, right? But what if I say, you should not even trust anyone who invites or offers you full remote access to their computers? Security researchers at cybersecurity firm Check Point have discovered more than two dozen vulnerabilities in both open-source RDP clients and Microsoft's own proprietary client that could allow a malicious RDP server to compromise a client computer, reversely. RDP, or Remote Desktop Protocol, allows users to connect to remote computers. The protocol is usually used by technical users and IT administrators to remotely connect to other devices on the network. RDP was initially developed by Microsoft for its Windows operating system, but there are several open source clients for the RDP protocol that can be used on Linux as well as Unix systems. Check Point researchers recently

If you can't find it on Google, you will definitely find it on the Dark Web . Black markets on the Dark web are not known for just buying drugs, it is a massive hidden network where you can buy pretty much anything you can imagine—from pornography, weapon, and counterfeit currencies, to hacking tools, exploits, malware, and zero-days. One such type of underground marketplace on Dark Web is RDP Shop, a platform from where anyone can buy RDP access (remote desktop protocol) to thousands of hacked machines for a small fee. While investigating several underground RDP shops, security researchers from the McAfee's Advanced Threat Research team discovered that someone is selling remote access linked to security systems at a major International airport for as low as $10. Yes, that's $10, I didn't miss any zeros. Instead of buying RDP credential, researchers used the Shodan search engine to find the correct IP address of the hacked Windows Server machine, whose ad

As part of this month's Patch Tuesday , Microsoft has released security patches for a serious privilege escalation vulnerability which affect all versions of its Windows operating system for enterprises released since 2007. Researchers at behavioral firewall specialist Preempt discovered two zero-day vulnerabilities in Windows NTLM security protocols, both of which allow attackers to create a new domain administrator account and get control of the entire domain. NT LAN Manager (NTLM) is an old authentication protocol used on networks that include systems running the Windows operating system and stand-alone systems. Although NTLM was replaced by Kerberos in Windows 2000 that adds greater security to systems on a network, NTLM is still supported by Microsoft and continues to be used widely. The first vulnerability involves unprotected Lightweight Directory Access Protocol (LDAP) from NTLM relay, and the second impact Remote Desktop Protocol (RDP) Restricted-Admin mode. L

Did you know… last month's widespread WannaCry ransomware attack forced Microsoft to release security updates against EternalBlue SMB exploit for unsupported versions of Windows, but the company left other three Windows zero-day exploits unpatched? For those unaware, EternalBlue is a Windows SMB flaw that was leaked by the Shadow Brokers in April and then abused by the WannaCry ransomware to infect nearly 300,000 computers in more than 150 countries within just 72 hours on 12th of May. Shortly after WannaCry outbreak, we reported that three unpatched Windows exploits , codenamed " EsteemAudit, " " ExplodingCan ," and " EnglishmanDentist ," were also being exploited by individuals and state-sponsored hackers in the wild. Specially EsteemAudit , one of the dangerous Windows hacking tool that targets remote desktop protocol (RDP) service on Microsoft Windows Server 2003 and Windows XP machines, while ExplodingCan exploits bugs in IIS 6.0 and E

While the rest of the world engaged in cyber security conferences and Anonymous operations, an Indian patriotic hacker used the time to attack Unofficial Pakistan Intelligence agency ISI. Hacker going by name " Godzilla " today claimed to hack into one of the server belongs to ISI website ( https://isi.org.pk ) and claimed steal possible information from website database. According to the information shared by hacker with ' The Hacker News ', he claims to have access to Remote Desktop Protocol (RDP) of the server located at 173.193.110.72. He disclose that System installed with Windows 2008 server standard edition and having three derives i.e C,D,E with operating system in C and Hostname ' AHCORP ' He also claimed to hack into MSSQL server containing 3 databases, with 9 users and located at https://mssql.isi.org.pk, as shown in screenshot taken by him. Some partial tables of the database ' msdb ' as listed below: bakupfile bakup

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
