Cisco Exploit Leaked in NSA Hack Modifies to Target Latest Version of Firewalls

Cisco Exploit Leaked in NSA Hack Modifies to Target Latest Version of Firewalls

August 24, 2016Mohit Kumar
Recently released NSA exploit from " The Shadow Brokers " leak that affects older versions of Cisco System firewalls can work against newer models as well. Dubbed ExtraBacon , the exploit was restricted to versions 8.4.(4) and earlier versions of Cisco's Adaptive Security Appliance (ASA) – a line of firewalls designed to protect corporate, government networks and data centers. However, the exploit has now been expanded to 9.2.(4) after researchers from Hungary-based security consultancy SilentSignal were able to modify the code of ExtraBacon to make it work on a much newer version of Cisco's ASA software. Both Cisco and Fortinet have confirmed their firewalls are affected by exploits listed in the Shadow Brokers cache that contained a set of " cyber weapons " stolen from the Equation Group . The Equation Group is an elite hacking group tied to the NSA's offensive Tailored Access Operations (TAO) and linked to the previous infamous Regin and S

Hackers are using Nuclear Exploit Kit to Spread Cryptowall 4.0 Ransomware

November 26, 2015Swati Khandelwal
Beware Internet Users! Cryptowall 4.0 – the newest version of the world's worst Ransomware – has surfaced in the Nuclear exploit kit , one of the most potent exploit kits available in the underground market for hacking into computers. Ransomware threat has emerged as one of the biggest threats to internet users in recent times. Typically, a Ransomware malware encrypts all files on victim's computer with a strong cryptographic algorithm, then demand a ransom to be paid in Bitcoin (range between $200 and $10,000). Cryptowall is currently among the most widespread and sophisticated family of Ransomware backed by a very robust back-end infrastructure. Also Read: Anyone can Now Create their Own Ransomware using This Hacking ToolKit The recent report dated back to last month suggested that the authors of Cryptowall 3.0 ransomware virus have managed to raise more than $325 Million in revenue in the past year alone. With the debut of Cryptowall 4.0 at the beg

Internet Explorer zero-day exploit targets U.S. nuke researchers

May 06, 2013Anonymous
Security researchers revealed that series of " Watering Hole " has been conducted exploiting a IE8 zero-day vulnerability to target U.S. Government experts working on nuclear weapons research. The news is not surprising but it is very concerning, the principal targets of the attacks are various groups of research such as the components of U.S. Department of Labor and the U.S. Department of Energy, the news has been confirmed by principal security firms and by Microsoft corporate. The flaw has been used in a series of "watering hole" attacks, let's remind that "Watering Hole" is a technique of attack realized compromising legitimate websites using a " drive-by " exploit. The attackers restrict their audience to a individuals interested to specific content proposed by targeted website, in this way when the victim visits the page a backdoor Trojan is installed on his computer. The website compromised to exploit the IE8 zero-day is the Dep
Bad Rabbit Ransomware Uses Leaked 'EternalRomance' NSA Exploit to Spread

Bad Rabbit Ransomware Uses Leaked 'EternalRomance' NSA Exploit to Spread

October 27, 2017Mohit Kumar
A new widespread ransomware worm, known as " Bad Rabbit ," that hit over 200 major organisations, primarily in Russia and Ukraine this week leverages a stolen NSA exploit released by the Shadow Brokers this April to spread across victims' networks. Earlier it was reported that this week's crypto-ransomware outbreak did not use any National Security Agency-developed exploits, neither EternalRomance nor EternalBlue , but a recent report from Cisco's Talos Security Intelligence revealed that the Bad Rabbit ransomware did use EternalRomance exploit. NotPetya ransomware (also known as ExPetr and Nyetya) that infected tens of thousands of systems back in June also leveraged the EternalRomance exploit , along with another NSA's leaked Windows hacking exploit EternalBlue, which was used in the WannaCry ransomware outbreak. Bad Rabbit Uses EternalRomance SMB RCE Exploit Bad Rabbit does not use EternalBlue but does leverage EternalRomance RCE exploit to spread
New Drammer Android Hack lets Apps take Full control (root) of your Phone

New Drammer Android Hack lets Apps take Full control (root) of your Phone

October 24, 2016Swati Khandelwal
Earlier last year, security researchers from Google's Project Zero outlined a way to hijack the computers running Linux by abusing a design flaw in the memory and gaining higher kernel privileges on the system. Now, the same previously found designing weakness has been exploited to gain unfettered "root" access to millions of Android smartphones, allowing potentially anyone to take control of affected devices. Researchers in the VUSec Lab at Vrije Universiteit Amsterdam have discovered a vulnerability that targets a device's dynamic random access memory (DRAM) using an attack called Rowhammer . Although we are already aware of the Rowhammer attack , this is the very first time when researchers have successfully used this attack to target mobile devices. What is DRAM Rowhammer Attack? The Rowhammer attack against mobile devices is equally dangerous because it potentially puts all critical data on millions of Android phones at risk, at least until a secu
FBI Used Firefox Exploit to Shutdown Illegal Site Running on Tor Network

FBI Used Firefox Exploit to Shutdown Illegal Site Running on Tor Network

August 05, 2013Mohit Kumar
TOR is the dark side of the Internet, the so-called dark web, which provides a safe haven to privacy advocates but is also where drugs, assassins for hire and other weird and illegal activities can allegedly be traded. A claimed zero-day vulnerability in Firefox 17 was used by the FBI to identify some users of the privacy-protecting Tor anonymity network. The FBI did not compromise the TOR network itself and The complex multi-layers of encryption still stand. Instead the FBI compromised the TOR browser only using a zero-day JavaScript exploit and used this to implant a cookie which fingerprinted users through a specific external server. Eric Eoin Marques , 28 year-old man in Ireland believed to be behind Freedom Hosting , the biggest service provider for sites on the encrypted Tor network , is awaiting extradition on p*rno charges. It is understood the FBI had spent a year trying to locate Mr Marques. Marques was arrested on a Maryland warrant that includes charges
Google Researcher Releases iOS Exploit—Could Enable iOS 11 Jailbreak

Google Researcher Releases iOS Exploit—Could Enable iOS 11 Jailbreak

December 11, 2017Swati Khandelwal
As promised last week , Google's Project Zero researcher Ian Beer now publicly disclosed an exploit that works on almost all 64-bit Apple devices running iOS 11.1.2 or earlier, which can be used to build an iOS jailbreak, allowing users to run apps from non-Apple sources. On Monday morning, Beer shared the details on the exploit, dubbed "tfp0," which leveraged double-free memory corruption vulnerabilities in the kernel, the core of the operating system. Here, " tfp0 " stands for " task for pid 0 " or the kernel task port—which gives users full control over the core of the operating system. The Project Zero researcher responsibly reported these vulnerabilities to Apple in October, which were patched by the company with the release of iOS 11.2 on 2nd December. While Beer says he has successfully tested his proof of concept exploit on the iPhone 6s and 7, and iPod Touch 6G, he believes that his exploit should work on all 64-bit Apple devices.

Hackers Use New Flash Zero-Day Exploit to Distribute FinFisher Spyware

October 16, 2017Mohit Kumar
FinSpy —the infamous surveillance malware is back and infecting high-profile targets using a new Adobe Flash zero-day exploit delivered through Microsoft Office documents. Security researchers from Kaspersky Labs have discovered a new zero-day remote code execution vulnerability in Adobe Flash, which was being actively exploited in the wild by a group of advanced persistent threat actors, known as BlackOasis . The critical type confusion vulnerability, tracked as CVE-2017-11292 , could lead to code execution and affects Flash Player 21.0.0.226 for major operating systems including Windows, Macintosh, Linux and Chrome OS. Researchers say BlackOasis is the same group of attackers which were also responsible for exploiting another zero-day vulnerability ( CVE-2017-8759 ) discovered by FireEye researchers in September 2017. Also, the final FinSpy payload in the current attacks exploiting Flash zero-day (CVE-2017-11292) shares the same command and control (C&C) server as the
Critical GHOST vulnerability affects most Linux Systems

Critical GHOST vulnerability affects most Linux Systems

January 28, 2015Swati Khandelwal
A highly critical vulnerability has been unearthed in the GNU C Library (glibc) , a widely used component of most Linux distributions, that could allow attackers to execute malicious code on servers and remotely gain control of Linux machines. The vulnerability, dubbed " GHOST " and assigned CVE-2015-0235 , was discovered and disclosed by the security researchers from Redwood Shores, California-based security firm Qualys on Tuesday. CRITICAL AS HEARTBLEED AND SHELLSHOCK GHOST is considered to be critical because hackers could exploit it to silently gain complete control of a targeted Linux system without having any prior knowledge of system credentials (i.e. administrative passwords). Also Read:  Top Best Password Managers . The flaw represents an immense Internet threat, in some ways similar to the Heartbleed ,   Shellshock   and Poodle   bugs that came to light last year. WHY GHOST ? The vulnerability in the GNU C Library (glibc) is dubbed GHOST b
New RIG Exploit Kit Campaign Infecting Victims' PCs with RedLine Stealer

New RIG Exploit Kit Campaign Infecting Victims' PCs with RedLine Stealer

April 28, 2022Ravie Lakshmanan
A new campaign leveraging an exploit kit has been observed abusing an Internet Explorer flaw patched by Microsoft last year to deliver the RedLine Stealer trojan. "When executed, RedLine Stealer performs recon against the target system (including username, hardware, browsers installed, anti-virus software) and then exfiltrates data (including passwords, saved credit cards, crypto wallets, VPN logins) to a remote command and control server," Bitdefender  said  in a new report shared with The Hacker News. Most of the infections are located in Brazil and Germany, followed by the U.S., Egypt, Canada, China, and Poland, among others. Exploit kits or exploit packs are comprehensive tools that contain a collection of exploits designed to take advantage of vulnerabilities in commonly-used software by scanning infected systems for different kinds of flaws and deploying additional malware. The primary infection method used by attackers to distribute exploit kits, in this case the
Hacker Discloses New Windows Zero-Day Exploit On Twitter

Hacker Discloses New Windows Zero-Day Exploit On Twitter

October 24, 2018Swati Khandelwal
A security researcher with Twitter alias SandboxEscaper—who two months ago publicly dropped a zero-day exploit for Microsoft Windows Task Scheduler—has yesterday released another proof-of-concept exploit for a new Windows zero-day vulnerability. SandboxEscaper posted a link to a Github page hosting a proof-of-concept (PoC) exploit for the vulnerability that appears to be a privilege escalation flaw residing in Microsoft Data Sharing (dssvc.dll). The Data Sharing Service is a local service that runs as LocalSystem account with extensive privileges and provides data brokering between applications. The flaw could allow a low-privileged attacker to elevate their privileges on a target system, though the PoC exploit code (deletebug.exe) released by the researcher only allows a low privileged user to delete critical system files—that otherwise would only be possible via admin level privileges. "Not the same bug I posted a while back, this doesn't write garbage to files
Cisco finds new Zero-Day Exploit linked to NSA Hackers

Cisco finds new Zero-Day Exploit linked to NSA Hackers

September 20, 2016Mohit Kumar
Network equipment vendor Cisco is finally warning its customers of another zero-day vulnerability the company discovered in the trove of NSA's hacking exploits and implants leaked by the group calling itself " The Shadow Brokers ." Last month, the Shadow Brokers published firewall exploits, implants, and hacking tools allegedly stolen from the NSA's Equation Group, which was designed to target major vendors including, Cisco, Juniper, and Fortinet. A hacking exploit, dubbed ExtraBacon , leveraged a zero-day vulnerability (CVE-2016-6366) resided in the Simple Network Management Protocol (SNMP) code of Cisco ASA software that could allow remote attackers to cause a reload of the affected system or execute malicious code. Now Cisco has found another zero-day exploit , dubbed "Benigncertain," which targets PIX firewalls. Cisco analyzed the exploit and noted that it had not identified any new flaws related to this exploit in its current products. But,
First Android Malware Found Exploiting Dirty COW Linux Flaw to Gain Root Privileges

First Android Malware Found Exploiting Dirty COW Linux Flaw to Gain Root Privileges

September 26, 2017Swati Khandelwal
Nearly a year after the disclosure of the Dirty COW vulnerability that affected the Linux kernel, cybercriminals have started exploiting the vulnerability against Android users, researchers have warned. Publicly disclosed last year in October, Dirty COW was present in a section of the Linux kernel—a part of virtually every Linux distribution, including Red Hat, Debian, and Ubuntu—for years and was actively exploited in the wild. The vulnerability allows an unprivileged local attacker to gain root access through a race condition issue, gain access to read-only root-owned executable files, and permit remote attacks. However, security researchers from Trend Micro published a blog post on Monday disclosing that the privilege escalation vulnerability (CVE-2016-5195), known as Dirty COW, has now been actively exploited by a malware sample of ZNIU, detected as AndroidOS_ZNIU. This is the first time we have seen a malware sample to contain an exploit for the vulnerability designed
Two Zero-Day Exploits Found After Someone Uploaded 'Unarmed' PoC to VirusTotal

Two Zero-Day Exploits Found After Someone Uploaded 'Unarmed' PoC to VirusTotal

July 02, 2018Swati Khandelwal
Security researchers at Microsoft have unveiled details of two critical and important zero-day vulnerabilities that had recently been discovered after someone uploaded a malicious PDF file to VirusTotal, and get patched before being used in the wild . In late March, researchers at ESET found a malicious PDF file on VirusTotal, which they shared with the security team at Microsoft "as a potential exploit for an unknown Windows kernel vulnerability." After analyzing the malicious PDF file, the Microsoft team found that the same file includes two different zero-day exploits—one for Adobe Acrobat and Reader, and the other targeting Microsoft Windows. Since the patches for both the vulnerabilities were released in the second week of May, Microsoft released details of both the vulnerabilities today, after giving users enough time to update their vulnerable operating systems and Adobe software. According to the researchers, the malicious PDF including both the zero-days e
Warning! Update Mozilla Firefox to Patch Critical File Stealing Vulnerability

Warning! Update Mozilla Firefox to Patch Critical File Stealing Vulnerability

August 07, 2015Swati Khandelwal
Earlier this week, Mozilla Security researcher Cody Crews discovered a malicious advertisement on a Russian news site that steals local files from a system and upload them to a Ukrainian server without the user ever knowing. The malicious advertisement was exploiting a serious vulnerability in Firefox's PDF Viewer and the JavaScript context in order to inject a script capable of searching sensitive files on user's local file systems . Mozilla versions of Firefox that do not contain the PDF Viewer, such as Firefox for Android, are not affected by the " Same origin violation and local file stealing via PDF reader " vulnerability. The exploit does not execute any arbitrary code but injects a JavaScript payload into the local file context, allowing the script to search for and upload potentially user's sensitive local files. All an attacker need to do is load the page with this exploit and sit back and relax. The exploit will silently steal files in t
