Super Cryptography : The Next Generation Encryption The next generation of encryption technologies meets this need by using Elliptic Curve Cryptography (ECC) to replace RSA and DH, and using Galois/Counter Mode (GCM) of the Advanced Encryption Standard (AES) block cipher for high-speed authenticated encryption. Elliptic curve cryptography (ECC) is an approach to public-key cryptography based on the algebraic structure of elliptic curves over finite fields. The use of elliptic curves in cryptography was suggested independently by Neal Koblitz and Victor S. Miller in 1985. According to Cisco ," New algorithms for encryption, authentication, digital signatures, and key exchange are needed to meet escalating security and performance requirements ". A 244-bit ECC key has the equivalent strength of a 2048-bit RSA key for security; a 384-bit ECC key matches a 7680-bit RSA key. Greater strength for any given key length enables the use of shorter keys, resulting in significantly l

A Palestinian Web Developer and Hacker, ' Khalil Shreateh ' found an interesting  vulnerability in Facebook, that allows hacker to bypass the Privacy settings to make a post on anyone's Timeline / Wall. He was forced to post vulnerability details on Mark Zuckerberg (Facebook Founder) Timeline to prove his point, after the Facebook Security Team failed to recognize his critical vulnerability three times. The flaw even working for those victims, who is not included in the attacker friend list.  According to Facebook's Bug Bounty program, a researcher has to submit the flaw details via email to Facebook Security Team without disclosing the details in Public. In order to get the minimum reward of US$500, the flaw should be valid. The reported vulnerability is in " composer.php " file on Facebook mechanism. First Khalil made a post on the timeline of a girl, " Sarah Gooden " who studied at the same college as Facebook CEO Mark Zuckerbe

Super Low RPO with Continuous Data Protection: Dial Back to Just Seconds Before an Attack Zerto , a Hewlett Packard Enterprise company, can help you detect and recover from ransomware in near real-time. This solution leverages continuous data protection (CDP) to ensure all workloads have the lowest recovery point objective (RPO) possible. The most valuable thing about CDP is that it does not use snapshots, agents, or any other periodic data protection methodology. Zerto has no impact on production workloads and can achieve RPOs in the region of 5-15 seconds across thousands of virtual machines simultaneously. For example, the environment in the image below has nearly 1,000 VMs being protected with an average RPO of just six seconds! Application-Centric Protection: Group Your VMs to Gain Application-Level Control   You can protect your VMs with the Zerto application-centric approach using Virtual Protection Groups (VPGs). This logical grouping of VMs ensures that your whole applica

In any organization, there are certain accounts that are designated as being privileged. These privileged accounts differ from standard user accounts in that they have permission to perform actions that go beyond what standard users can do. The actions vary based on the nature of the account but can include anything from setting up new user accounts to shutting down mission-critical systems. Privileged accounts are essential tools. Without these accounts, the IT staff would be unable to do its job. At the same time, privileged accounts can pose a serious threat to an organization's security. Added risk of a privileged account  Imagine for a moment that a hacker manages to steal a standard user's password and is able to log in as that user. Even though the hacker would have access to certain resources at that point, they would be constrained by the user's privileges (or lack thereof). In other words, the hacker would be able to browse the Internet, open some applications, and access

Microsoft today released security updates to fix a total of 115 new security vulnerabilities in various versions of its Windows operating system and related software—making March 2020 edition the biggest ever Patch Tuesday in the company's history. Of the 115 bugs spanning its various products — Microsoft Windows, Edge browser, Internet Explorer, Exchange Server, Office, Azure, Windows Defender, and Visual Studio — that received new patches, 26 have been rated as critical, 88 received a severity of important, and one is moderate in severity. However, unlike last month , none of the vulnerabilities the tech giant patched this month are listed as being publicly known or under active attack at the time of release. It's worth highlighting that the patch addresses critical flaws that could be potentially exploited by bad actors to execute malicious code by specially crafted LNK files and word documents. Titled "LNK Remote Code Execution Vulnerability" ( CVE-2020

Google has released its monthly security updates for the Android operating system, addressing 46 new software vulnerabilities. Among these, three vulnerabilities have been identified as actively exploited in targeted attacks. One of the vulnerabilities tracked as CVE-2023-26083 is a memory leak flaw affecting the Arm Mali GPU driver for Bifrost, Avalon, and Valhall chips. This particular vulnerability was exploited in a previous attack that enabled spyware infiltration on Samsung devices in December 2022. This vulnerability was regarded as serious enough to prompt the Cybersecurity and Infrastructure Security Agency (CISA) to issue a patching order for federal agencies in April 2023. Another significant vulnerability, identified as CVE-2021-29256, is a high-severity issue that affects specific versions of the Bifrost and Midgard Arm Mali GPU kernel drivers. This flaw permits an unprivileged user to gain unauthorized access to sensitive data and escalate privileges to the root lev

A team of security researchers has discovered another serious side-channel vulnerability in Intel CPUs that could allow an attacker to sniff out sensitive protected data, like passwords and cryptographic keys, from other processes running in the same CPU core with simultaneous multi-threading feature enabled. The vulnerability, codenamed PortSmash (CVE-2018-5407), has joined the list of other dangerous side-channel vulnerabilities discovered in the past year, including Meltdown and Spectre , TLBleed , and Foreshadow . Discovered by a team of security researchers from the Tampere University of Technology in Finland and Technical University of Havana, Cuba, the new side-channel vulnerability resides in Intel's Hyper-Threading technology, the company's implementation of Simultaneous MultiThreading (SMT). Simultaneous MultiThreading is a performance feature that works by splitting up each physical core of a processor into virtual cores, known as threads, allowing each core to

Security researchers have discovered a nasty security vulnerability that is said to affect almost every version of Windows and Samba and will be patched on April 12, 2016, the Samba development team announced Tuesday. So, Save the Date if you are a Windows or Samba file server administrator. Samba is a free, open source implementation of the SMB/CIFS network file sharing protocol that runs on the majority of operating systems available today, including Windows, UNIX, Linux, IBM System 390, and OpenVMS. Samba allows non-Windows operating systems, like GNU/Linux or Mac OS X, to communicate with the same networking protocol as the Windows products, thus enabling users to access network shared folders and files from Windows OS. Dubbed Badlock , the vulnerability has been discovered by Stefan Metzmacher, a developer of Samba Core Team. Details about the Badlock vulnerability will be disclosed on April 12, when the developers of Microsoft and Samba release security p

Developers of phpMyAdmin, one of the most popular and widely used MySQL database management systems, today released an updated version 4.8.4 of its software to patch several important vulnerabilities that could eventually allow remote attackers to take control of the affected web servers. The phpMyAdmin project last Sunday gave an early heads-up about the latest security update through its blog, probably the first time, as an experiment to find if pre-announcements can help website admins, hosting providers and package managers better prepare for the security release. "We are inspired by the workflow of other projects (such as Mediawiki and others) which often announce any security release in advance to allow package maintainers and hosting providers to prepare. We are experimenting to see if such a workflow is suitable for our project," phpMyAdmin release manager Isaac Bennetch told The Hacker News. phpMyAdmin is a free, open-source administration tool for managing

After exposing private tweets , plaintext passwords , and personal information for hundreds of thousands of its users, here is a new security blunder social networking company Twitter admitted today. Twitter announced that the phone numbers and email addresses of some users provided for two-factor authentication (2FA) protection had been used for targeted advertising purposes—though the company said it was 'unintentional.' In a blog post, the company said an 'error' in its 'Tailored Audiences and Partner Audiences advertising system' inadvertently used the information provided by users for security reasons to run targeted ads based on the advertisers' own marketing lists. "When an advertiser uploaded their marketing list, we may have matched people on Twitter to their list based on the email or phone number the Twitter account holder provided for safety and security purposes. This was an error and we apologize," Twitter said in a blog po

Startups and scales-ups are often cloud-first organizations and rarely have sprawling legacy on-prem environments. Likewise, knowing the agility and flexibility that cloud environments provide, the mid-market is predominantly running in a hybrid state, partly in the cloud but with some on-prem assets. While there has been a bit of a backswing against the pricing and lock-in presented when using cloud infrastructure, cloud is still the preferred provider for the majority of SMBs. As a result, external attack surfaces are increasingly complex and distributed and, therefore, harder to monitor and secure. This expanded attack surface gives hackers plenty of blind spots and gaps to exploit. Security teams are on the back, reacting, often too slowly, to changes in their own attack surface as engineering teams continuously spin up and expose new systems, services, and data to the internet. This is compounded by the fact that the threat landscape is always changing. Thousands of new vulne

In a US SEC (Securities and Exchange Commission)  8-K filing , Omnicell, the healthcare technology provider, revealed that some of its products, services, and internal systems were affected by ransomware.  Upon detecting the incident, the medication management systems provider took immediate action to contain the attack and ensure continued operation. In its  10-Q form  filing, Omnicell disclosed that cyber-attacks or data breaches disrupted its business.  Will you be the next victim? If you overlook the importance of data protection, attackers can get you in no time.  Explore the  impact of the data breach  on the healthcare sector and what preventive measures can be taken against such attacks. Omnicell Announced Data Breach  Founded in 1992, Omnicell is a leading provider of medication management solutions for hospitals, long-term care facilities, and retail pharmacies.  On May 4, 2022 , Omnicell's IT systems and third-party cloud services were affected by ransomware attac

Research in Motion has found a security flaw and recommended that user disable JavaScript in browsers on certain phones, threatening the BlackBerry maker's iron-clad reputation for security. "The issue could result in remote code execution on affected BlackBerry smartphones," the Waterloo, Ontario-based company said. "Successful exploitation of the vulnerability requires the user to browse to a website that the attacker has maliciously designed." The flaw is in the WebKit browser that RIM includes in version 6 of its BlackBerry OS. RIM said hackers can steal data from users' memory cards on some BlackBerry devices. They can also install malware by exploiting the hole, but the company said that even if attacked, the phone's emails and contacts would be safe. The publicity is particularly bad for the company who stakes its reputation on the security and privacy of its service. RIM, which has been forced to use more third-party software to compete w

More than a dozen security flaws have been disclosed in E11, a smart intercom product made by Chinese company Akuvox . "The vulnerabilities could allow attackers to execute code remotely in order to activate and control the device's camera and microphone, steal video and images, or gain a network foothold," Claroty security researcher Vera Mens  said  in a technical write-up. Akuvox E11 is described by the company on its website as a " SIP  [Session Initiation Protocol] video doorphone specially designed for villas, houses, and apartments." The  product listing , however, has been taken down from the website, displaying an error message: "Page does not exist." A  snapshot  captured by Google shows that the page was live as recently as March 12, 2023, 05:59:51 GMT. The attacks can manifest either through remote code execution within the local area network (LAN) or remote activation of the E11's camera and microphone, allowing the adversary to c

An ongoing crypto mining campaign has upgraded its arsenal while evolving its defense evasion tactics that enable the threat actors to conceal the intrusions and fly under the radar, new research published today has revealed. Since first detected in 2019, a total of 84 attacks against its honeypot servers have been recorded to date, four of which transpired in 2021, according to researchers from DevSecOps and cloud security firm Aqua Security, who have been tracking the malware operation for the past three years. That said, 125 attacks have been spotted in the wild in the third quarter of 2021 alone, signaling that the attacks have not slowed down. Initial attacks involved executing a malicious command upon running a vanilla image named "alpine:latest" that resulted in the download of a shell script named "autom.sh." "Adversaries commonly use vanilla images along with malicious commands to perform their attacks, because most organizations trust the official

If you applied for financing from T-Mobile anytime between 1 September 2013 and 16 September 2015, you have been HACKED! – even if you never had T-Mobile service. T-Mobile's credit application processor Experian was hacked, potentially exposing the highly personal information of more than 15 million people in the United States. The stolen information includes names, addresses, phone numbers and – most unfortunately – Social Security numbers . The massive data breach was first discovered in mid-September and has now been confirmed by T-Mobile CEO John Legere . According to Legere, Hackers successfully obtained Millions of people's private information through Experian, one of the world's largest credit check companies that process T-Mobile's credit applications. Both customers and people who submitted to a T-Mobile credit check ( but either canceled or never activated their T-Mobile service ) between September 1, 2013, and September 16, 2015, are most at ris

Last week, application security company ImmuniWeb released a new free tool  to monitor and measure an organization's exposure on the Dark Web. To improve the decision-making process for cybersecurity professionals, the free tool crawls Dark Web marketplaces, hacking forums, and Surface Web resources such as Pastebin or GitHub to provide you with a classified schema of your data being offered for sale or leaked. All you need to launch a Dark Web search is to enter your domain name. The volume of stolen credentials on the Dark Web is booming This week, over 26 million user records, including plaintext passwords, stolen from LiveJournal appeared on a Dark Web marketplace for as low as $35. The present week is likewise sadly marked with a compromise of 31 SQL databases (with 1.6 million rows of client data) from webshop owners. There were 7,098 breaches reported in 2019, exposing over 15.1 billion records, a new worst year on record according to Risk Based Security report
