Critical Flaws Found in Windows NTLM Security Protocol – Patch Now

Critical Flaws Found in Windows NTLM Security Protocol – Patch Now
July 12, 2017Swati Khandelwal
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

Original Author of Petya Ransomware is Back & He Wants to Help NotPetya Victims

Original Author of Petya Ransomware is Back & He Wants to Help NotPetya Victims
June 29, 2017Swati Khandelwal
The author of original Petya ransomware is back. After 6 months of silence, the author of the now infamous Petya ransomware appeared today on Twitter to help victims unlock their files encrypted by a new version of Petya, also known as NotPetya . "We're back having a look in NotPetya," tweeted Janus, a name Petya creator previously chose for himself from a villain in James Bond. "Maybe it's crackable with our privkey. Please upload the first 1MB of an infected device, that would help." This statement made by the Petya author suggests he may have held onto a master decryption key , which if it works for the new variant of Petya infected files, the victims would be able to decrypt their files locked in the recent cyber outcry. Janus sold Petya as a Ransomware-as-a-Service (RaaS) to other hackers in March 2016, and like any regular ransomware, original Petya was designed to lock victim's computer, then return them when a ransom is paid.

Microsoft Releases Patches for 3 Remaining NSA Windows Exploits
June 14, 2017Mohit Kumar
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

Newly Found Malware Uses 7 NSA Hacking Tools, Where WannaCry Uses 2

Newly Found Malware Uses 7 NSA Hacking Tools, Where WannaCry Uses 2
May 22, 2017Swati Khandelwal
A security researcher has identified a new strain of malware that also spreads itself by exploiting flaws in Windows SMB file sharing protocol, but unlike the WannaCry Ransomware that uses only two leaked NSA hacking tools , it exploits all the seven. Last week, we warned you about multiple hacking groups exploiting leaked NSA hacking tools, but almost all of them were making use of only two tools: EternalBlue and DoublePulsar. Now, Miroslav Stampar, a security researcher who created famous 'sqlmap' tool and now a member of the Croatian Government CERT, has discovered a new network worm, dubbed EternalRocks , which is more dangerous than WannaCry and has no kill-switch in it. Unlike WannaCry, EternalRocks seems to be designed to function secretly in order to ensure that it remains undetectable on the affected system. However, Stampar learned of EternalRocks after it infected his SMB honeypot . The NSA exploits used by EternalRocks, which Stampar called " Do

May 19, 2017Mohit Kumar
Since the Shadow Brokers released the zero-day software vulnerabilities and hacking tools – allegedly belonged to the NSA's elite hacking team Equation Group – several hacking groups and individual hackers have started using them in their own way. The April's data dump was believed to be the most damaging release by the Shadow Brokers till the date, as it publicly leaked lots of Windows hacking tools , including dangerous Windows SMB exploit. After the outbreak of WannaCry last week, security researchers have identified multiple different campaigns exploiting Windows SMB vulnerability (CVE-2017-0143), called Eternalblue , which has already compromised hundreds of thousands of computers worldwide. I have been even confirmed by multiple sources in hacking and intelligence community that there are lots of groups and individuals who are actively exploiting Eternalblue for different motives.

Warning! This Cross-Platform Malware Can Hack Windows, Linux and OS X Computers
September 07, 2016Swati Khandelwal
Unlike specially crafted malware specifically developed to take advantage of Windows operating system platform, cyber attackers have started creating cross-platform malware for wider exploitation. Due to the rise in popularity of Mac OS X and other Windows desktop alternatives, hackers have begun designing cross-platform malware modularly for wide distribution. Cross-platform malware is loaded with specialized payloads and components, allowing it to run on multiple platforms. One such malware family has recently been discovered by researchers at Kaspersky Lab, which run on all the key operating systems, including Windows, Linux, and Mac OS X. Stefan Ortloff, a researcher from Kaspersky Lab's Global Research and Analysis Team, first discovered the Linux and Windows variants of this family of cross-platform backdoor, dubbed Mokes , in January this year. Now, the researcher today confirmed the existence of an OS X variant of this malware family, explaining a technical breakd

Oops! Microsoft Accidentally Leaks Backdoor Keys to Bypass UEFI Secure Boot

Oops! Microsoft Accidentally Leaks Backdoor Keys to Bypass UEFI Secure Boot
August 10, 2016Swati Khandelwal
It's True  —  There is no such backdoor that only its creator can access. Microsoft has accidentally leaked the Secret keys that allow hackers to unlock devices protected by UEFI ( Unified Extensible Firmware Interface ) Secure Boot feature. What's even worse? It will be impossible for Microsoft to undo its leak. Secure Boot is a security feature that protects your device from certain types of malware, such as a rootkit, which can hijack your system bootloader, as well as, Secure Boot restricts you from running any non-Microsoft operating system on your device. In other words, when Secure Boot is enabled, you will only be able to boot Microsoft approved ( cryptographically signature checking ) operating systems. However, the Golden Keys disclosed by two security researchers, using alias MY123 and Slipstream , can be used to install non-Windows operating systems, say GNU/Linux or Android, on the devices protected by Secure Boot. Moreover, according to the blog pos

February 24, 2015Swati Khandelwal
A critical vulnerability has been fixed in Samba — Open Source standard Windows interoperability suite of programs for Linux and Unix, that could have allowed hackers to remotely execute an arbitrary code in the Samba daemon ( smbd ). Samba is an open source implementation of the SMB/CIFS network file sharing protocol that works on the majority of operating systems available today, which allows a non-Windows server to communicate with the same networking protocol as the Windows products. Samba is supported by many operating systems including Windows 95/98/NT, OS/2, and Linux. smbd is the server daemon of Samba which provides file sharing and printing services to clients using the SMB/CIFS protocol. Samba is also sometimes installed as a component of *BSD and OS X systems. The vulnerability, designated as CVE-2015-0240 , actually resides in this smbd file server daemon.

New Variant of Emotet Banking Malware targets German Users
January 07, 2015Swati Khandelwal
A new Spam email campaign making the rounds in Germany are delivering a new variant of a powerful banking malware , a financial threat designed to steal users' online banking credentials, according to security researchers from Microsoft. The malware, identified as Emotet , was first spotted last June by security vendors at Trend Micro. The most standout features of Emotet is its network sniffing ability , which enables it to capture data sent over secured HTTPS connections by hooking into eight network APIs, according to Trend Micro. Microsoft has been monitoring a new variant of Emotet banking malware , Trojan:Win32/Emotet.C , since November last year. This new variant was sent out as part of a spam email campaign that peaked in November. Emotet has been distributed through spam messages, which either contain a link to a website hosting the malware or a PDF document icon that is actually the malware.
