A Company Offers $500,000 For Secure Messaging Apps Zero-Day Exploits

A Company Offers $500,000 For Secure Messaging Apps Zero-Day Exploits
August 24, 2017Swati Khandelwal
How much does your privacy cost? It will soon be sold for half a Million US dollars. A controversial company specialises in acquiring and reselling zero-day exploits is ready to pay up to US$500,000 for working zero-day vulnerabilities targeting popular secure messenger applications, such as Signal, Telegram and WhatsApp. Zerodium announced a new pricing structure on Wednesday, paying out $500,000 for fully functional remote code execution (RCE) and local privilege escalation (LPE) vulnerabilities in Signal, WhatsApp, iMessage, Viber, Facebook Messenger, WeChat, and Telegram. The payouts for all these secure messengers have been increased after tech companies introduced end-to-end encryption in their apps, making it more difficult for anyone to compromise their messaging platforms. The same payout is offered for remote code execution and local privilege escalation security flaws in default mobile email applications. Launched in 2015, Zerodium is a Washington, DC-based p

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

Shadow Brokers Launches 0-Day Exploit Subscriptions for $21,000 Per Month

Shadow Brokers Launches 0-Day Exploit Subscriptions for $21,000 Per Month
May 30, 2017Swati Khandelwal
As promised to release more zero-days exploits and hacking tools for various platforms starting from June 2017, the infamous hacking group Shadow Brokers is back with more information on how to subscribe and become a private member for receiving exclusive access to the future leaks. The Shadow Brokers is the same hacking group who leaked NSA's built Windows hacking tools and zero-day exploits in public that led to the WannaCry menace . When the Shadow Brokers promised its June 2017 release two weeks ago, the group announced that it would sell new zero-day exploits and hacking tools only to the private members with paid monthly subscription, instead of making them public for everyone. How to Become Member of the 'Wine of Month' Club? Now, just a few minutes ago, the hacking collective has released details about how to participate in the monthly subscription model – or the "Wine of Month Club," as the group called it – to get exclusive access to the

Brace yourselves for a possible 'second wave' of massive global cyber attack, as SMB ( Server Message Block) was not the only network protocol whose zero-day exploits created by NSA were exposed in the Shadow Brokers dump last month. Although Microsoft released patches for SMB flaws for supported versions in March and unsupported versions immediately after the outbreak of the WannaCry ransomware, the company ignored to patch other three NSA hacking tools, dubbed " EnglishmanDentist ," " EsteemAudit ," and " ExplodingCan ." It has been almost two weeks since WannaCry ransomware began to spread, which infected nearly 300,000 computers in more than 150 countries within just 72 hours, though now it has been slowed down. For those unaware, WannaCry exploited a Windows zero-day SMB bug that allowed remote hackers to hijack PCs running on unpatched Windows OS and then spread itself to other unpatched systems using its wormable capability.

Shadow Brokers, Who Leaked WannaCry SMB Exploit, Are Back With More 0-Days

Shadow Brokers, Who Leaked WannaCry SMB Exploit, Are Back With More 0-Days
May 16, 2017Swati Khandelwal
The infamous hacking collective Shadow Brokers – the one who leaked the Windows SMB exploit in public that led to last weekend's WannaCrypt menace – are back, this time, to cause more damage. In typically broken English, the Shadow Brokers published a fresh statement (with full of frustration) a few hours ago, promising to release more zero-day bugs and exploits for various desktop and mobile platforms starting from June 2017. However, this time the Shadow Brokers leaks will not be available for everybody, as the hacking collective said: "TheShadowBrokers is launching new monthly subscription model. Is being like [the] wine of month club. Each month peoples can be paying membership fee, then getting members only data dump each month." To some extent, this is good news, but it is terrible news too. Good because now all these upcoming alleged unpatched vulnerabilities will be patched after being disclosed and terrible because the group will sell new zero-day e

Not Just Criminals, But Governments Were Also Using MS Word 0-Day Exploit

Not Just Criminals, But Governments Were Also Using MS Word 0-Day Exploit
April 13, 2017Swati Khandelwal
Recently we reported about a critical code execution vulnerability in Microsoft Word that was being exploited in the wild by cyber criminal groups to distribute malware like Dridex banking trojans and Latentbot. Now, it turns out that the same previously undisclosed vulnerability in Word (CVE-2017-0199) was also actively being exploited by the government-sponsored hackers to spy on Russian targets since at least this January. The news comes after security firm FireEye, that independently discovered this flaw last month, published a blog post , revealing that FinSpy spyware was installed as early as January using the same vulnerability in Word that was patched on Tuesday by Microsoft. For those unaware, the vulnerability (CVE-2017-0199) is a code execution flaw in Word that could allow an attacker to take over a fully patched and up to date computer when the victim opens a Word document containing a booby-trapped OLE2link object, which downloads a malicious HTML app from a

Beware of an Unpatched Microsoft Word 0-Day Flaw being Exploited in the Wild

Beware of an Unpatched Microsoft Word 0-Day Flaw being Exploited in the Wild
April 09, 2017Swati Khandelwal
It's 2017, and opening a simple MS Word file could compromise your system. Security researchers are warning of a new in-the-wild attack that silently installs malware on fully-patched computers by exploiting a serious — and yet unpatched — zero-day vulnerability in all current versions of Microsoft Office. The Microsoft Office zero-day attack, uncovered by researchers from security firms McAfee and FireEye, starts simply with an email that attaches a malicious Word file containing a booby-trapped OLE2link object. When opened, the exploit code gets executed and makes a connection to a remote server controlled by the attacker, from where it downloads a malicious HTML application file (HTA) that's disguised as a document created in Microsoft's RTF (Rich Text Format). The HTA file then gets executed automatically with attackers gaining full code execution on the victim's machine, downloading additional payloads from "different well-known malware families"

Shadow Brokers Group Releases More Stolen NSA Hacking Tools & Exploits

Shadow Brokers Group Releases More Stolen NSA Hacking Tools & Exploits
April 08, 2017Mohit Kumar
Remember The Shadow Brokers ? They are back. A hackers group that previously claimed to have stolen a bunch of hacking tools (malware, zero-day exploits, and implants) created by the NSA and gained popularity last year for leaking a portion of those tools is back. Today, The Shadow Brokers group released more alleged hacking tools and exploits that, the group claims, belonged to " Equation Group " – an elite cyber attack unit linked to the NSA. Besides dumping some NSA's hacking tools back in August 2016, the Shadow Brokers also released an encrypted cache of files containing more NSA's hacking tools and exploits in an auction, asking for 1 Million Bitcoins (around $568 Million). However, after failed auction , the group put up those hacking tools and exploits for direct sale on an underground website, categorizing them into a type — like "exploits," "Trojans," and "implant" — each of which ranged from 1 to 100 Bitcoins (fr

New Apache Struts Zero-Day Vulnerability Being Exploited in the Wild
March 09, 2017Swati Khandelwal
Security researchers have discovered a Zero-Day vulnerability in the popular Apache Struts web application framework, which is being actively exploited in the wild. Apache Struts is a free, open-source, Model-View-Controller (MVC) framework for creating elegant, modern Java web applications, which supports REST, AJAX, and JSON. In a blog post published Monday, Cisco's Threat intelligence firm Talos announced the team observed a number of active attacks against the zero-day vulnerability (CVE-2017-5638) in Apache Struts. According to the researchers, the issue is a remote code execution vulnerability in the Jakarta Multipart parser of Apache Struts that could allow an attacker to execute malicious commands on the server when uploading files based on the parser. "It is possible to perform an RCE attack with a malicious Content-Type value," warned Apache. "If the Content-Type value isn't valid an exception is thrown which is then used to display an erro

Update — Hacker Claims to Have Hacked the FBI, But It Wasn't
January 05, 2017Mohit Kumar
Update: A hacker yesterday claimed to have hacked the FBI's website running on Plone CMS, but it seems it wasn't hacked using any zero-day vulnerability in Plone. We contacted Plone security team and updated this story (see below) with official statements. A hacker, using Twitter handle CyberZeist , has claimed to have hacked the FBI's website (fbi.gov) and leaked personal account information of several FBI agents publically. CyberZeist had initially exposed the flaw on 22 December, giving the FBI time to patch the vulnerability in its website's code before making the data public. The hacker exploited a zero-day vulnerability in the Plone CMS , an Open Source Content Management software used by FBI to host its website, and leaked personal data of 155 FBI officials to Pastebin , including their names, passwords, and email accounts. CyberZeist tweeted multiple screenshots as proof of his claims, showing his unauthorized access to server and database files usi

Ex-NSA Contractor Stole 50 TB of Classified Data; Includes Top-Secret Hacking Tools
October 21, 2016Swati Khandelwal
Almost two months ago, the FBI quietly arrested NSA contractor Harold Thomas Martin III for stealing an enormous number of top secret documents from the intelligence agency. Now, according to a court document filed Thursday, the FBI seized at least 50 terabytes of data from 51-year-old Martin that he siphoned from government computers over two decades. The stolen data that are at least 500 million pages of government records includes top-secret information about "national defense." If all data stolen by Martin found indeed classified, it would be the largest NSA heist, far bigger than Edward Snowden leaks. According to the new filing, Martin also took "six full bankers' boxes" worth of documents, many of which were marked "Secret" and "Top Secret." The stolen data also include the personal information of government employees. The stolen documents date from between 1996 through 2016. "The document appears to have been printed by the

Zerodium Offers $1.5 Million Bounty For iOS Zero-Day Exploits
September 30, 2016Mohit Kumar
Well, there's some good news for Hackers and Bug hunters, though a terrible news for Apple! Exploit vendor Zerodium has tripled its bug bounty for an Apple's iOS 10 zero-day exploit, offering a maximum payout of $US1.5 Million. Yes, $1,500,000.00 Reward. That's more than seven times what Apple is offering (up to $200,000) for iOS zero-days via its private, invite-only bug bounty program. Zerodium, a startup by the infamous French-based company Vupen that buys and sells zero-day exploits to government agencies around the world, previously offered US$500,000 for remote iOS 9 jailbreaks, which was temporarily increased to $1 Million for a competition help by the company last year. The company paid out $1 million contest reward for the first three iOS 9 zero-days in November to an unnamed hacker group, then lowered the price again to $500,000. With the recent release of iOS 10, Zerodium has agreed to pay $1.5 Million to anyone who can pull off a remote jail

Leaked NSA Hacking Tools Were 'Mistakenly' Left By An Agent On A Remote Server
September 23, 2016Swati Khandelwal
If you are a hacker, you might have enjoyed the NSA's private zero-day exploits , malware and hacking tools that were leaked last month. But the question is: How these hacking tools ended up into the hands of hackers? It has been found that the NSA itself was not directly hacked, but a former NSA employee carelessly left those hacking tools on a remote server three years ago after an operation and a group of Russian hackers found them, sources close to the investigation told Reuters . The leaked hacking tools, which enable hackers to exploit vulnerabilities in systems from big vendors like Cisco Systems, Juniper, and Fortinet, were dumped publicly online by the group calling itself " The Shadow Brokers ." NSA officials have also admitted to the FBI that their careless employee acknowledged the error shortly afterward, and hence the agency was aware of its operative's mistake from last three years. But instead of warning the affected companies that their c

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,

Blackhat Firm Offers $500,000 for Zero-day iOS Exploit; Double Than Apple’s Highest Bounty
August 11, 2016Mohit Kumar
Last week, Apple finally announced a bug bounty program for researchers and white hat hackers to find and get paid for reporting details of zero-day vulnerabilities in its software and devices. The company offers the biggest payout of $200,000, which is 10 times the maximum reward that Google offers and double the highest bounty paid by Microsoft. But now Apple is going to face competition from a blackhat company named, Exodus Intelligence.
