Active Directory has a number of different components to keep track of user and resource information in an organization…. If one piece starts to fail and a recovery effort falters, it could mean it’s time for a rebuilding process. The system volume (SYSVOL) is a shared folder found on domain controllers in an Active Directory
Remember the Simjacker vulnerability? Earlier this month, we reported about a critical unpatched weakness in a wide range of SIM cards, which an unnamed surveillance company has actively been exploiting in the wild to remotely compromise targeted mobile phones just by sending a specially crafted SMS to their phone numbers. If you can recall, the
Malware or computer virus can infect your computer in several different ways, but one of the most common methods of its delivery is through malicious file attachments over emails that execute the malware when you open them. Therefore, to protect its users from malicious scripts and executable, Microsoft is planning to blacklist 38 additional file
A distributed denial of service, or DDoS, attack is a method to bring down a service by sending a flood of legitimate or illegitimate requests from multiple source devices. The goal is to overwhelm the target device so that it can no longer operate normally. Let’s examine two: network layer and application layer DDoS attacks.
A team of Canadian cybersecurity researchers has uncovered a sophisticated and targeted mobile hacking campaign that is targeting high-profile members of various Tibetan groups with one-click exploits for iOS and Android devices. Dubbed Poison Carp by University of Toronto’s Citizen Lab, the hacking group behind this campaign sent tailored malicious web links to its targets
Data is at the heart of AI, fueling machine learning models to help companies obtain more accurate predictions, gain better insights and increase sales. Recently, the way companies are acquiring and using the data that powers those models is being evaluated. For many years, companies have been complacent toward how their third parties obtain critical
An anonymous hacker today publicly revealed details and proof-of-concept exploit code for an unpatched, critical zero-day remote code execution vulnerability in vBulletin—one of the widely used internet forum software. One of the reasons why the vulnerability should be viewed as a severe issue is not just because it is remotely exploitable, but also doesn’t require
Advanced Persistent Threats groups were once considered a problem that concerns Fortune 100 companies only. However, the threat landscape of the recent years tells otherwise—in fact, every organization, regardless of vertical and size is at risk, whether as a direct target, supply chain or collateral damage. The vast majority of security decision-makers acknowledge they need
Among its other capabilities, the 5G network supports slicing, a technique that divides a single physical network infrastructure into multiple virtual networks. Compared to existing 4G and LTE (Long Term Evolution) networks, 5G promises significant improvements in bandwidth and latency, making virtual network slices a possibility. Each virtual network instance created by 5G network slicing
A cybersecurity researcher recently published details and proof-of-concept for an unpatched zero-day vulnerability in phpMyAdmin—one of the most popular applications for managing the MySQL and MariaDB databases. phpMyAdmin is a free and open source administration tool for MySQL and MariaDB that’s widely used to manage the database for websites created with WordPress, Joomla, and many
Encrypting web content is nothing new: It’s been nearly 20 years since the publication of the specification for encrypting web content by running HTTP over the Transport Layer Security protocol. However, running a secure encrypted web server has gone from an option to a virtual necessity in recent years. Attackers continue to seek — and
Ecuador officials have arrested the general manager of IT consulting firm Novaestrat after the personal details of almost the entire population of the Republic of Ecuador left exposed online in what seems to be the most significant data breach in the country’s history. Personal records of more than 20 million adults and children, both dead
Two widely used Adblocker Google Chrome extensions mimicking as — AdBlock and uBlock Origin — have been caught stuffing cookies in the web browser of millions of users to generate affiliate income from referral schemes fraudulently. There’s no doubt web extensions add a lot of useful features to web browsers, making your online experience great
Whether organizations truly need a cybersecurity framework is one of the biggest questions that’s never really asked in information security. This is because some vendors focus on selling spot security products, an approach that doesn’t lend itself to encouraging enterprises to step back and look at security in the overall context of what they are
Google has released an urgent software update for its Chrome web browser and is urging Windows, Mac, and Linux users to upgrade the application to the latest available version immediately. Started rolling out to users worldwide this Wednesday, the Chrome 77.0.3865.90 version contains security patches for 1 critical and 3 high-risk security vulnerabilities, the most
It’s relatively easy to manage device encryption when there are only iOS devices in a mobile fleet. Apple provides a single encryption standard across all of the iOS devices it manufactures. Android device encryption, however, depends on the version of Android the devices run, the OEM and device model, the hardware architecture and other factors.
Insecure Internet-connected devices have aided different types of cybercrime for years, most common being DDoS and spam campaigns. But cybercriminals have now shifted toward a profitable scheme where botnets do not just launch DDoS or spam—they mine cryptocurrencies as well. Smominru, an infamous cryptocurrency-mining and credential-stealing botnet, has become one of the rapidly spreading computer
The United States government today filed a lawsuit against Edward Snowden, a former employee of the CIA and NSA government agencies who made headlines worldwide in 2013 when he fled the country and leaked top-secret information about NSA’s global and domestic surveillance activities. And you would be more surprised to know the reason for this
After nine years running, DerbyCon held its ninth and final show, and attendees and a co-founder looked back on the conference and discussed plans to continue the community with smaller groups around the world. DerbyCon was one of the more popular small-scale hacker conferences held in the U.S., but organizers surprised the infosec community in
The massive data breach at Capital One – America’s seventh-largest bank, according to revenue – has challenged many common assumptions about cloud computing for the first time. Ironically, the incident, which exposed some 106 million Capital One customers’ accounts, has only reinforced the belief that the cloud remains the safest way to store sensitive data.
Estonian based web security startup WebARX, the company who is also behind open-source plugin vulnerability scanner WPBullet and soon-to-be-released bug bounty platform plugbounty.com, has a big vision for a safer web. It built a defensive core for websites which is embedded deep inside the company’s DNA as even ARX in their name refers to the
The United States Treasury Department on Friday announced sanctions against three state-sponsored North Korean hacking groups for conducting several destructive cyberattacks on US critical infrastructure. Besides this, the hacking groups have also been accused of stealing possibly hundreds of millions of dollars from financial institutions around the world to ultimately fund the North Korean government’s
Network bridges and switches are distinctly different, serving separate functions. A bridge is a point-to-point… connection joining two LANs using the same protocol, such as Ethernet. A switch is a multiport bridge that connects multiple clients and chooses the packet path on the network. Every switch is a bridge, but bridges are not truly switches.
Good news… next week, on September 19, Apple will roll out iOS 13, the latest version of its mobile operating system. Yes, we’re excited about, but here comes the bad news… iOS 13 contains a vulnerability that could allow anyone to bypass the lockscreen protection on your iPhone and access some sensitive information. Jose Rodriguez,
It’s time for two important disciplines — business continuity and its related initiatives and cybersecurity — to collaborate better. Typically, cybersecurity and business continuity operate in different silos, but I’m keen to move them closer together, as they are both important elements of an organization’s resilience. For example, a cybersecurity event, which is initially addressed
Cybersecurity researchers today revealed the existence of a new and previously undetected critical vulnerability in SIM cards that could allow remote attackers to compromise targeted mobile phones and spy on victims just by sending an SMS. Dubbed “SimJacker,” the vulnerability resides in a particular piece of software, called the S@T Browser, a dynamic SIM toolkit
CISOs and CIOs need to know better than anyone the security pulse of their organizations. On the other hand, they cannot be flooded with every changing detail. Finding the right balance that enables them to clearly grasp the big picture required in making sound decisions is a task many security executives find challenging. Threat actors
Keeping a unified communications environment secure is no small task as the different communications tools that comprise a UC system have their own security needs. And organizations can’t push all the security responsibilities onto their UC vendor. Organizations must take steps to lock down their networks to support unified communications security. Learn how to build
Get your update caps on. Microsoft today released its monthly Patch Tuesday update for September 2019, patching a total of 79 security vulnerabilities in its software, of which 17 are rated critical, 61 as important, and one moderate in severity. Two of the security vulnerabilities patched by the tech giant this month are listed as
In many ways, biometric authentication is superior to a traditional password due to its convenience and resistance to common attack vectors. But biometric authentication still faces its fair share of threats. If a hacker gains access to a user’s biometric data, that user can’t reset their biometrics the way they might reset a compromised password.
