Watch out Apple users! The default mailing app pre-installed on millions of iPhones and iPads has been found vulnerable to two critical flaws that attackers are exploiting in the wild, at least, from the last two years to spy on high-profile victims. The flaws could eventually let remote hackers secretly take complete control over Apple devices just by sending an email to any targeted individual with his email account logged-in to the vulnerable app. According to cybersecurity researchers at ZecOps, the bugs in question are remote code execution flaws that reside in the MIME library of Apple's mail app—first, due to an out-of-bounds write bug and second, is a heap overflow issue. Though both flaws get triggered while processing the content of an email, the second flaw is more dangerous because it can be exploited with 'zero-click,' where no interaction is required from the targeted recipients. 8-Years-Old Apple Zero-Days Exploited in the Wild According to the...

Beware, If you are using S/MIME protocol over Microsoft Outlook to encrypt your email communication, you need to watch out. From at least last 6 months, your messages were being sent in both encrypted and unencrypted forms, exposing all your secret and sensitive communications to potential eavesdroppers. S/MIME, or Secure/Multipurpose Internet Mail Extensions, is an end-to-end encryption protocol—based on public-key cryptography and works just like SSL connections—that enables users to send digitally signed and encrypted messages. According to a security advisory published by SEC Consult earlier this week, a severe bug (CVE-2017-11776) in Microsoft Outlook email client causes S/MIME encrypted emails to be sent with their unencrypted versions attached. When Outlook users make use of S/MIME to encrypt their messages and format their emails as plain text, the vulnerability allows the seemingly encrypted emails to be sent in both encrypted as well as human-readable clear text f...

It's time to gear up your systems and software for the latest July 2018 Microsoft security patch updates. Microsoft today released security patch updates for 53 vulnerabilities, affecting Windows, Internet Explorer (IE), Edge, ChakraCore, .NET Framework, ASP.NET, PowerShell, Visual Studio, and Microsoft Office and Office Services, and Adobe Flash Player. Out of 53 vulnerabilities, 17 are rated critical, 34 important, one moderate and one as low in severity.

Critical Flaws Patched In Microsoft Products Most of the critical issues are memory corruption flaws in IE, Edge browser and Chakra scripting engine, which if successfully exploited, could allow an unauthenticated, remote attacker to execute arbitrary code on a targeted system in the context of the cur...

Cybersecurity researchers are warning about active exploitation attempts targeting a newly disclosed security flaw in Synacor's Zimbra Collaboration. Enterprise security firm Proofpoint said it began observing the activity starting September 28, 2024. The attacks seek to exploit CVE-2024-45519 , a severe security flaw in Zimbra's postjournal service that could enable unauthenticated attackers to execute arbitrary commands on affected installations. "The emails spoofing Gmail were sent to bogus addresses in the CC fields in an attempt for Zimbra servers to parse and execute them as commands," Proofpoint said in a series of posts on X. "The addresses contained Base64 strings that are executed with the sh utility." The critical issue was addressed by Zimbra in versions 8.8.15 Patch 46, 9.0.0 Patch 41, 10.0.9, and 10.1.1 released on September 4, 2024. A security researcher named lebr0nli (Alan Li) has been credited with discovering and reporting the short...

A zero-day flaw in the Zimbra Collaboration email software was exploited by four different groups in real-world attacks to pilfer email data, user credentials, and authentication tokens. "Most of this activity occurred after the initial fix became public on GitHub," Google Threat Analysis Group (TAG)  said  in a report shared with The Hacker News. The flaw, tracked as  CVE-2023-37580  (CVSS score: 6.1), is a  reflected cross-site scripting  (XSS) vulnerability impacting versions before 8.8.15 Patch 41. It was  addressed  by Zimbra as part of patches released on July 25, 2023. Successful exploitation of the shortcoming could allow execution of malicious scripts on the victims' web browser simply by tricking them into clicking on a specially crafted URL, effectively initiating the XSS request to Zimbra and reflecting the attack back to the user. Google TAG, whose researcher Clément Lecigne was credited with discovering and reporting the bug, s...

Cybersecurity researchers have discovered a new critical vulnerability ( CVE-2020-7247 ) in the OpenSMTPD email server that could allow remote attackers to take complete control over BSD and many Linux based servers. OpenSMTPD is an open-source implementation of the server-side SMTP protocol that was initially developed as part of the OpenBSD project but now comes pre-installed on many UNIX-based systems. According to Qualys Research Labs, who discovered this vulnerability, the issue resides in the OpenSMTPD's sender address validation function, called smtp_mailaddr(), which can be exploited to execute arbitrary shell commands with elevated root privileges on a vulnerable server just by sending specially crafted SMTP messages to it. The flaw affects OpenBSD version 6.6 and works against the default configuration for both, the locally enabled interface as well as remotely if the daemon has been enabled to listen on all interfaces and accepts external mail. "Exploit...

British sensationalist Newspaper Daily Mail Hacked by TeaMp0isoN Yesterday Visitors to the Daily Mail's recipe pages ( https://recipes.dailymail.co.uk/index.htm )  had been confronted with a message left by hackers who defaced and disabled the site. British sensationalist newspaper the Daily Mail has been hit by hackers in support of the online movement Opcensorthis.  News of the hack spread via Twitter and it seems to have happened late afternoon on Sunday, 5 February, and lasted for a couple of hours. A mirror link posted on the TeaMp0isoN Twitter gives those that missed it a look at what the hackers were promoting. " For years you've poisoned the mainstream media with your sensationalist, ultranationalist nonsense, continuing to inject reader's minds with anti- immigration and borderline racist propaganda ," says the text on the deface web page. " Your distorted bias on news is wrongly justified by patriotism and conservatism, though we see through yo...

The bug in Microsoft Word 2002, 2003, 2007 and 2010 was patched Nov. 9 as part of Microsoft's monthly security update. Word 2008 and 2011 for the Mac have also been patched, but Microsoft has not yet issued a fix for the same flaw in the older Word 2004. The circulating attacks affect only Windows versions of the suite, however. According to the Microsoft Malware Protection Center (MMPC), the group that investigates attack code and issues signature updates for the company's antivirus software, the first in-the-wild exploits were detected last week. When Microsoft shipped the Word patch last month, it rated the bug as "1" on its exploitability index, meaning it believed a working attack would pop up within 30 days. The attack uses a malicious RTF (Rich Text Format) file to generate a stack overflow in Word on Windows, said MMPC researcher Rodel Finones. Following a successful exploit, the attack code downloads and runs a Trojan horse on the compromised computer...

A recently disclosed critical security flaw impacting the Aviatrix Controller cloud networking platform has come under active exploitation in the wild to deploy backdoors and cryptocurrency miners. Cloud security firm Wiz said it's currently responding to "multiple incidents" involving the weaponization of CVE-2024-50603 (CVSS score: 10.0), a maximum severity bug that could result in unauthenticated remote code execution. Put differently, a successful exploitation of the flaw could permit an attacker to inject malicious operating system commands owing to the fact that certain API endpoints do not adequately sanitize user-supplied input. The vulnerability has been addressed in versions 7.1.4191 and 7.2.4996. Jakub Korepta, a security researcher at Polish cybersecurity company Securing, has been credited with discovering and reporting the shortcoming. A proof-of-concept (PoC) exploit has since been made publicly available . Data gathered by the cybersecurity company...

After the discovery of a critical vulnerability that could have allowed hackers to view private Yahoo Mail images, Yahoo retired the image-processing library ImageMagick. ImageMagick is an open-source image processing library that lets users resize, scale, crop, watermarking and tweak images. The tool is supported by PHP, Python, Ruby, Perl, C++, and many other programming languages. This popular image-processing library made headline last year with the discovery of the then-zero-day vulnerability, dubbed ImageTragick , which allowed hackers to execute malicious code on a Web server by uploading a maliciously-crafted image. Now, just last week, security researcher Chris Evans demonstrated an 18-byte exploit to the public that could be used to cause Yahoo servers to leak other users' private Yahoo! Mail image attachments. 'Yahoobleed' Bug Leaks Images From Server Memory The exploit abuses a security vulnerability in the ImageMagick library, which Evans dubbed...

A critical vulnerability has been discovered in the Google Apps for Work that allows hackers to abuse any website's domain name based email addresses, which could then be used to send phishing emails on company's behalf in order to target users. If you wish to have an email address named on your brand that reads like admin@yourdomain.com instead of myemail@gmail.com , then you can register an account with Google Apps for Work. The Google Apps for Work service allows you to use Gmail, Drive storage, Calendar, online documents, video Hangouts, and other collaborative services with your team or organization. To get a custom domain name based email service from Google, one just need to sign up like a normal Gmail account. Once created, you can access your domain's admin console panel on Google app interface, but can not be able to use any service until you get your domain verified from Google.

Bulletien second will address a Remote Code Execution flaw in Microsoft Office that can be triggered simply by previewing an email in Outlook, even without explicitly opening the e-mail. The problem for users is that Outlook automatically displays the content of each email it previews. The remaining 10 bulletins are all rated important by Microsoft, four of them patch remote code execution flaws in Office, while three other privilege esc...

A security researcher has discovered and publicly disclosed two critical vulnerabilities in the popular Internet mail message transfer agent Exim , one of which could allow a remote attacker to execute malicious code on the targeted server. Exim is an open source mail transfer agent (MTA) developed for Unix-like operating systems such as Linux, Mac OSX or Solaris, which is responsible for routing, delivering and receiving email messages. The first vulnerability, identified as CVE-2017-16943 , is a use-after-free bug which could be exploited to remotely execute arbitrary code in the SMTP server by crafting a sequence of BDAT commands. "To trigger this bug, BDAT command is necessary to perform an allocation by raising an error," the researcher said. "Through our research, we confirm that this vulnerability can be exploited to remote code execution if the binary is not compiled with PIE." The researcher ( mehqq_ ) has also published a Proof-of-Concept (PoC) ...

Cybersecurity researchers have discovered multiple security vulnerabilities in Zimbra email collaboration software that could be potentially exploited to compromise email accounts by sending a malicious message and even achieve a full takeover of the mail server when hosted on a cloud infrastructure. The flaws — tracked as CVE-2021-35208 and CVE-2021-35208 — were discovered and reported in Zimbra 8.8.15 by researchers from code quality and security solutions provider SonarSource in May 2021. Mitigations have since been  released  in Zimbra versions 8.8.15 Patch 23 and 9.0.0 Patch 16. CVE-2021-35208  (CVSS score: 5.4) - Stored XSS Vulnerability in ZmMailMsgView.java CVE-2021-35209  (CVSS score: 6.1) - Proxy Servlet Open Redirect Vulnerability "A combination of these vulnerabilities could enable an unauthenticated attacker to compromise a complete Zimbra webmail server of a targeted organization,"  said  SonarSource vulnerability researcher, Simon Sc...

Oh Microsoft, How could you do this to your own Internet Explorer? Microsoft had kept hidden a critical Zero-Day vulnerability of Internet explorer 8 from all of us, since October 2013. A Critical zero-day Internet Explorer vulnerability ( CVE-2014-1770 ), which was discovered by Peter 'corelanc0d3r' Van Eeckhoutte in October 2013 just goes public today by the Zero Day Initiative (ZDI) website . Zero Day Initiative is a program for rewarding security researchers for responsibly disclosing vulnerabilities. ZDI reportedly disclosed the vulnerability to Microsoft when it was first identified by one of its researchers, on which Microsoft responded 4 month later on February 2014 and confirmed the flaw, but neither the Microsoft patch the vulnerability nor it disclosed any details about it. But due to ZDI's 180 days public notification policy, they are obligated to publicly disclosed the details of a Zero-Day vulnerability. ZDI warned Microsoft several days ago ab...

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" ...

Equifax, one of the three largest credit-reporting firms in the United States, has to pay up to $700 million in fines to settle a series of state and federal investigations into the massive 2017 data breach that exposed the personal and financial data of nearly 150 million Americans—that's almost half the country. According to an official announcement by the U.S. Federal Trade Commission (FTC) today, Equifax has agreed to pay at least $575 million in fines, but this penalty could rise to up to $700 million depending on the amount of compensation people claim. Up to $425 million of the fines will go to a fund that will provide credit monitoring services to affected customers and compensate anyone who bought such services from the company and paid other related expenses as a result of the breach . Rest $175 million and $100 million will go to civil penalties across 50 states and to the Consumer Financial Protection Bureau (CFPB), respectively. Besides the penalty, the co...
