Android malware loaded with Linux kernel privilege escalation exploit
Jun 12, 2013
Malware authors are notorious for quickly leveraging new exploits in the public domain for nefarious purposes. A recently discovered Linux kernel Local privilege escalation exploit , which allows attackers to gain complete control of infected devices, has been ported to the Android smartphone platform. The Linux kernel 2.6.x, including Red Hat Enterprise Linux 6, Ubuntu 12.04 LTS, Debian 6 and Suse Enterprise Linux 11 are vulnerable to privilege escalation flaw with CVE-2013-2094 .  CVE-2013-2094 states, " The perf_swevent_init function in kernel/events/core.c in the Linux kernel before 3.8.9 uses an incorrect integer data type, which allows local users to gain privileges via a crafted perf_event_open system call. " Exploit for Linux machines is publically available here . Privilege escalation exploits are particularly dangerous as they can allow cybercriminals to gain complete control over the compromised device.  The exploit can be used to to access d

Ruby on Rails exploit could hijack unpatched servers for botnet

Ruby on Rails exploit could hijack unpatched servers for botnet
May 31, 2013
Server Administrators are being urged to update their Ruby on Rails servers following the discovery of an active malware campaign targeting vulnerable versions of the web development framework. According to security researcher Jeff Jarmoc , Hackers are exploiting a known and patched vulnerability in coding language Ruby on Rails, which allows a remote user to edit the web server's crontab to download a file to the /tmp directory where it is compiled and executed. The exploit that is currently being used by attackers adds a custom cron job (a scheduled task on Linux machines) that executes a sequence of commands. " Functionality is limited, but includes the ability to download and execute files as commanded, as well as changing servers ," Jarmoc blogged. " There's no authentication performed, so an enterprising individual could hijack these bots fairly easily by joining the IRC server and issuing the appropriate commands ." The original fla

Network Threats: A Step-by-Step Attack Demonstration
Apr 25, 2024Endpoint Security / Cyber Security
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

Windows zero day vulnerability publicly exposed by Google engineer
May 23, 2013
A Google security engineer has not only discovered a Windows zero-day flaw, but has also stated that Microsoft has a knack of treating outside researchers with great hostility. Tavis Ormandy , a Google security engineer, exposed the flaw on Full Disclosure , that could be used to crash PCs or gain additional access rights. The issue is less critical than other flaws as it's not a remotely exploitable one. Ormandy said on Full Disclosure, " I don't have much free time to work on silly Microsoft code, so I'm looking for ideas on how to fix the final obstacle for exploitation. ". He's been working on it for months, and according to a later post, he has now a working exploit that " grants SYSTEM on all currently supported versions of Windows. "  " I have a working exploit that grants SYSTEM on all currently supported versions of Windows. Code is available on request to students from reputable schools ," Ormandy adds. Microsoft acknowledged

May 01, 2013
Distributed Denial of Service attacks have increased in scale, intensity and frequency. The wide range of motives for these attacks political , criminal, or social makes every merchant or organization with an online presence a potential target. Over the weekend Incapsula mitigated a unique DDoS attack against a large gaming website, in which they have discovered a DDoS attack using thousands of legitimate WordPress blogs without the need for them to be compromised. Incapsula released the list of approximately 2,500 WordPress sites from where the attack was originated, including some very large sites like Trendmicro.com, Gizmodo.it and Zendesk.com . In a recent report , we posted about another method for DDoS attacks using DNS amplification , where a DNS request is made to an open DNS resolver with the source IP address forged so that it is the IP address of the targeted site to which the response is thus sent, but this new method uses HTTP rather than DNS.

Chrome, Firefox, Java, IE10 exploited at Pwn2Own competition
Mar 07, 2013
During the first day of Pwn2Own competition at the CanSecWest conference in Vancouver , latest versions of all major browsers were exploited by hackers.  Chrome, Firefox and Internet Explorer 10 on Windows 8 were successfully pwned by various competitors, bringing them tens of thousands of dollars in prizes.  French vulnerability research and bug selling firm ' Vupen ' brought down IE10 running on a Windows 8 powered Surface Pro tablet by exploiting a pair of flaws. Researchers Jon Butler and Nils from MWR Labs managed to exploit Google Chrome on Windows 7 and also used a kernel bug to bypass the sandbox. " By visiting a malicious webpage, it was possible to exploit a vulnerability which allowed us to gain code execution in the context of the sandboxed renderer process. We also used a kernel vulnerability in the underlying operating system in order to gain elevated privileges and to execute arbitrary commands outside of the sandbox with system privi

Two new Java zero-day vulnerabilities reported to Oracle

Two new Java zero-day vulnerabilities reported to Oracle
Feb 26, 2013
A Polish security firm ' Security Explorations' reported two new Java zero-day vulnerabilities , as " issue 54 " and "issue 55 ," with proof of concept code to Oracle. Oracle's security team is currently investigating the issue, but the status flaws not yet confirmed by Oracle. Less than a week after Oracle released its latest Java critical patch update, Researcher and Security Explorations's CEO Adam Gowdiak  have found two previously unknown security issues affecting Java 7. Security experts generally advise users to disable the Java browser plugin, which was exploited in recent targeted attacks on developers at Facebook , Apple and Microsoft. Java has faced an increasing number of zero-day vulnerabilities, bugs that are exploited by criminals before those flaws are patched, or even known by the vendor. Gowdiak confirmed that these newest vulnerabilities can be combined to circumvent Java's anti-exploit sandbox technology and used to attack

BlackBerry Enterprise Servers vulnerable to TIFF Image based Exploit

BlackBerry Enterprise Servers vulnerable to TIFF Image based Exploit
Feb 19, 2013
If you are a BlackBerry Enterprise Network user, here is something you need to be careful about. BlackBerry Enterprise Server (BES) users have been warned that an image-based exploit could allow hackers to access and execute code on the servers used to support corporate users of BlackBerry smartphones.  The flaw that been rated as high severity and actual vulnerability in BlackBerry Enterprise Servers resulted from how the server processes image files. Scenario to Exploit Vulnerability :  A malicious person writes a special code and then embeds it in a TIFF image file. The person then convinces a Blackberry smart phone user (whose phone is connected to a corporate BES) to view the TIFF file. As soon as the image file loads on the phone, the code runs on the Blackberry Enterprise server and either opens up a back door in the network or causes the network to crash altogether as instructed in the basic code. " RIM is not aware of any attacks on or specifically target

Distributed Red Team Operations with Cobalt Strike

Distributed Red Team Operations with Cobalt Strike
Feb 12, 2013
What if you could easily host malicious websites, send phishing emails, and manage compromised hosts across diverse internet addresses? This week's Cobalt Strike adds the ability to manage multiple attack servers at once. Here's how it works: When you connect to two or more servers, Cobalt Strike will show a switch bar with buttons for each server at the bottom of your window. Click a button to make that server active. It's a lot like using tabs to switch between pages in a web browser. To make use of multiple servers, designate a role for each one. Assign names to each server's button to easily remember its role. Dumbly connecting to multiple servers isn't very exciting. The fun comes when you seamlessly use Cobalt Strike features between servers. For example: Designate one server for phishing and another for reconnaissance. Go to the reconnaissance server, setup the system profiler website. Use the phishing tool to deliver the reconnaissance website through

Remote Root access vulnerability in Routers with Broadcom chipsets
Feb 02, 2013
DefenseCode researchers have discovered a critical security vulnerability that allows remote unauthenticated attacker to remotely execute arbitrary code under root privileges in the UPnP (Universal Plug and Play) implementation developed by Broadcom and used by many routers with Broadcom chipsets. Routers with vulnerable Broadcom UPnP stack are mostly based on Broadcom chipset. " We have found that, in fact, same vulnerable firmware component is also used in at least two other Cisco Linksys models - WRT54G3G and probably WRT310N. Could be others. " researchers said . The vulnerability is located within the wanipc and wanppp modules of the Broadcom UPnP stack, which is used by manufacturers that deliver routers based on the Broadcom chipset. The UPnP service is intended to be used on local networks, but Rapid7 found that there are over 80 million devices on the Internet that respond to UPnP discovery requests, making them vulnerable to remote attacks. The vul

Nov 14, 2012
Yesterday we have reported that How Bug Bounty programs can play unfair with hackers and researchers, where hackers are submitting their legitimate findings to companies and no surprise if they are getting replies that " Someone else already reported this, you are not eligible for Bounty ". But the main issue is, if companies are really aware about the issue , then why they have not fixed it yet ?  Today we are going to Talk about Google, that How a ignored vulnerability can be brilliantly crafted and exploited by Hackers for phishing users. On 11th September this year, I have reported a persistent XSS vulnerability in Google and reply from Google Security Team was," It seems the XSS you reported actually executes on one of our sandboxed domains (googleusercontent.com). The sandboxed domain does not contain any session cookies for google services, nor does it have access to any Google.com data " I said its okay if they are sure about it that it

Adobe Reader zero-day vulnerability with modified Blackhole Exploit-Kit
Nov 08, 2012
Group-IB , a Russian cybercrime investigation company has discovered a zero-day vulnerability, affects Adobe Reader X and Adobe Reader XI. The vulnerability is also included in new modified version of Blackhole Exploit-Kit , which is used for the distributing the banking Trojans (Zeus, Spyeye, Carberp, Citadel) with the help of exploitation different vulnerabilities in client-side software. The particular exploit is available in underground forums for as much as $50,000 and bug is dangerous because it permits cybercriminals to run arbitrary shellcode by bypassing the sandbox feature integrated into the more recent versions of Adobe Reader. For now this flaw is distributed only in only small circles of the underground but it has the potential for much larger post-exploitation methods. The exploit is limited to  Microsoft Windows installations of Adobe Reader and it can't be fully executed until the user closes his Web browser (or Reader). Adobe representatives said that
