The major internet outage across the United States earlier this week was not due to any virus or malware or state-sponsored cyber attack, rather it was the result of a simple TYPO. Amazon on Thursday admitted that an incorrectly typed command during a routine debugging of the company's billing system caused the 5-hour-long outage of some Amazon Web Services (AWS) servers on Tuesday. The issue caused tens of thousands of websites and services to become completely unavailable, while others show broken images and links, which left online users around the world confused. The sites and services affected by the disruption include Quora, Slack, Medium, Giphy, Trello, Splitwise, Soundcloud, and IFTTT, among a ton of others. Here's What Happened: On Tuesday morning, members of Amazon Simple Storage Service (S3) team were debugging the S3 cloud-storage billing system. As part of the process, the team needed to take a few billing servers offline, but unfortunately, it end...

Bad News for privacy concerned people! It will be once again easier for Internet Service Providers (ISPs) to sell your personal data for marketing or advertisement purposes without taking your permission. Last October, the United States Federal Communications Commission (FCC) passed a set of privacy rules on ISPs that restrict them from sharing your online data with third parties without your consent and require them to adopt "reasonable measures" to protect consumers' data from hackers. However, now the FCC suspended privacy rules before they came into effect. The reason? President Donald Trump's newly appointed FCC chairman Ajit Pai, a Republican and ex-Verizon lawyer. Ajit Pai, who has openly expressed his views against net neutrality in the past, just last week said during a speech at Mobile World Congress that Net Neutrality was "a mistake" and indicated that the Commission is now moving back to internet regulations. Now, Pai suspends p...

Last year Google employees took an initiative to help thousands of Open Source Projects patch a critical remote code execution vulnerability in a widely used Apache Commons Collections (ACC) library. Dubbed Operation Rosehub , the initiative was volunteered by some 50 Google employees, who utilized 20 percent of their work time to patch over 2600 open source projects on Github, those were vulnerable to "Mad Gadget vulnerability." Mad Gadget vulnerability ( CVE-2015-6420 ) is a remote code execution bug in the Java deserialization used by the Apache Commons Collections (ACC) library that could allow an unauthenticated, remote attacker to execute arbitrary code on a system. The ACC Library is widely deployed by many Java applications to decode data passed between computers. To exploit this flaw, all an unauthorized attacker need to do is submit maliciously crafted input to an application on a targeted system that uses the ACC library. Once the vulnerable ACC libra...

I had the honor of hosting the first episode of the Xposure Podcast live from Xposure Summit 2025. And I couldn't have asked for a better kickoff panel: three cybersecurity leaders who don't just talk security, they live it. Let me introduce them. Alex Delay , CISO at IDB Bank, knows what it means to defend a highly regulated environment. Ben Mead , Director of Cybersecurity at Avidity Biosciences, brings a forward-thinking security perspective that reflects the innovation behind Avidity's targeted RNA therapeutics. Last but not least, Michael Francess , Director of Cybersecurity Advanced Threat at Wyndham Hotels and Resorts, leads the charge in protecting the franchise. Each brought a unique vantage point to a common challenge: applying Continuous Threat Exposure Management (CTEM) to complex production environments. Gartner made waves in 2023 with a bold prediction: organizations that prioritize CTEM will be three times less likely to be breached by 2026. But here's the kicker -...

Yahoo has just revealed that around 32 million user accounts were accessed by hackers in the last two years using a sophisticated cookie forging attack without any password. These compromised accounts are in addition to the Yahoo accounts affected by the two massive data breaches that the company disclosed in last few months. The former tech giant said that in a regulatory filing Wednesday that the cookie caper is likely linked to the "same state-sponsored actor" thought to be behind a separate, 2014 data breach that resulted in the theft of 500 Million user accounts . "Based on the investigation, we believe an unauthorized third party accessed the company's proprietary code to learn how to forge certain cookies," Yahoo said in its annual report filed with the US Securities and Exchange Commission (SEC). "The outside forensic experts have identified approximately 32 million user accounts for which they believe forged cookies were used or taken...

Security researchers have discovered a new variant of Dridex – one of the most nefarious banking Trojans actively targeting financial sector – with a new, sophisticated code injection technique and evasive capabilities called " AtomBombing ." On Tuesday, Magal Baz, security researcher at Trusteer IBM  disclosed new research, exposing the new Dridex version 4, which is the latest version of the infamous financial Trojan and its new capabilities. Dridex is one of the most well-known Trojans that exhibits the typical behavior of monitoring a victim's traffic to bank sites by infiltrating victim PCs using macros embedded in Microsoft documents or via web injection attacks and then stealing online banking credentials and financial data. However, by including AtomBombing capabilities, Dridex becomes the first ever malware sample to utilize such sophisticated code injection technique to evade detection. What is "AtomBombing" Technique? Code injection te...

If you are also searching for the answers to what skills are needed for a job in cyber security, you should know that this varies widely based upon the responsibilities of a particular role, the type of company you want to work with, and especially on it's IT architect. However, Linux is the most required skills in information technology and cyber security, as Linux are everywhere! Whether you know it or not you are already using Linux every day – when you Google, you use Linux; when you buy metro tickets, you use Linux; It powers your smart devices; most airplane or automobile entertainment systems are also running on Linux; even your Android phone is Linux. Moreover, nearly all of the hacking and penetration testing tools are developed specifically for Linux. In fact, one of the popular operating systems of hackers, KALI, is also a Linux distro that comes with over 300 tools for penetration testing, forensics, hacking and reverse engineering. So, due to the rapid growth of Li...

Is anything safe? It's 2017, and the likely answer is NO. Making sure your passwords are secure is one of the first line of defense – for your computer, email, and information – against hacking attempts, and Password Managers are the one recommended by many security experts to keep all your passwords secure in one place. Password Managers are software that creates complex passwords, stores them and organizes all your passwords for your computers, websites, applications and networks, as well as remember them on your behalf. But what if your Password Managers itself are vulnerable? Well, it's not just an imagination, as a new report has revealed that some of the most popular password managers are affected by critical vulnerabilities that can expose user credentials. The report, published on Tuesday by a group of security experts from TeamSIK of the Fraunhofer Institute for Secure Information Technology in Germany, revealed that nine of the most popular Android pass...

With the evolving hacking events around us, cyber-security skills are in high demand across all organizations and industries, because a shortage of skilled cyber security practitioners could leave an organization vulnerable to cyber attacks. But knowledge alone is not sufficient, 'certification as eligibility' also matters, which shows employers that you are serious about your career and eligible as you have demonstrated your technical ability in some form. I frequently receive emails and messages from my readers asking: Should I get certified?, Are certifications important to build up a career in IT?, What certifications can one get to start a career in information security? and more. These are some of the most frequent queries I came across, and in this article, I will attempt to answer these along with a solution on how to get started. Whether you are looking to launch your career in the IT industry, or perhaps get promoted at your current job — getting certified ...

What could be more exciting for hackers than exploiting a vulnerability in a widely used software without having to struggle too much? One such easy-to-exploit, but critical vulnerability has been discovered in ESET's antivirus software that could allow any unauthenticated attackers to remotely execute arbitrary code with root privileges on a Mac system. The critical security flaw, tracked as CVE-2016-9892, in ESET Endpoint Antivirus 6 for macOS was discovered by Google Security Team's researchers Jason Geffner and Jan Bee at the beginning of November 2016. As detailed in the full disclosure , all a hacker needs to get root-level remote code execution on a Mac computer is to intercept the ESET antivirus package's connection to its backend servers using a self-signed HTTPS certificate, put himself in as a man-in-the-middle (MITM) attacker, and exploit an XML library flaw. The actual issue was related to a service named esets_daemon, which runs as root. The service...

Every parent should think twice before handing out Internet-connected toys or smart toys to their children, as these creepy toys pose a different sort of danger: privacy and data security risks for kids who play with them. This same incident was happened over a year ago when Hong Kong toymaker VTech was hacked , which exposed personal details, including snaps of parents and children and chat logs, of about 6.4 million children around the world. Now, in the latest security failing of the internet-connected smart toys, more than 2 Million voice recordings of children and their parents have been exposed, along with email addresses and passwords for over 820,000 user accounts. And What's even Worse? The hackers locked this data and held it for Ransom. California-based Spiral Toys' line of internet-connected stuffed animal toys, CloudPets , which allow children and relatives to send recorded voicemails back and forth, reportedly left the voice messages recorded between pare...

This month has yet been kind of interesting for cyber security researchers, with Google successfully cracked SHA1 and the discovery of Cloudbleed bug in Cloudflare that caused the leakage of sensitive information across sites hosted behind Cloudflare. Besides this, Google last week disclosed an unpatched vulnerability in Windows Graphics Device Interface (GDI) library, which affects Microsoft's Windows operating systems ranging from Windows Vista Service Pack 2 to the latest Windows 10. While the Windows vulnerability has yet to be patched by the company, Google today released the details of another unpatched Windows security flaw in its browser, as Microsoft did not act within its 90-day disclosure deadline. The vulnerability (CVE-2017-0037), discovered and disclosed by Google Project Zero team's researcher Ivan Fratric, is a so-called " type confusion flaw " in a module in Microsoft Edge and Internet Explorer that potentially leads to arbitrary code exec...

Wi-Fi enabled devices — widely known as the Internet of Things (IoT) — are populating offices and homes in greater and greater numbers. From smartphones to connected printers and even coffee makers, most of these IoT devices have good intentions and can connect to your company's network without a problem. However, as the Internet of Things (IoT) devices are growing at a great pace, they continue to widen the attack surface at the same time, giving attackers a large number of entry points to affect you some or the other way. The attackers can use your smart devices to gain backdoor entry to your network, giving them the capability to steal sensitive data, such as your personal information, along with a multitude of other malicious acts. An interesting attack scenario has recently been demonstrated by one of the renowned hackers, Jayson Street , who said all it is needed is to walk around with the right device to get into someone's device. Before we jump into the te...

A severe security vulnerability has been discovered in the CloudFlare content delivery network that has caused big-name websites to expose private session keys and other sensitive data. CloudFlare, a content delivery network (CDN) and web security provider that helps optimize safety and performance of over 5.5 Million websites on the Internet, is warning its customers of the critical bug that could have exposed a range of sensitive information, including passwords, and cookies and tokens used to authenticate users. Dubbed Cloudbleed , the nasty flaw is named after the Heartbleed bug that was discovered in 2014, but believed to be worse than Heartbleed. The vulnerability is so severe that it not only affects websites on the CloudFlare network but affects mobile apps as well. What exactly is "Cloudbleed," how it works, how are you affected by this bug, and how you can protect yourself? Let's figure it out. What is Cloudbleed? Discovered by Google Project Ze...

British police have arrested a suspect in connection with the massive attack on Deutsche Telekom that hit nearly 1 Million routers last November. Late last year, someone knocked down more than 900,000 broadband routers belonging to Deutsche Telekom users in Germany, which affected the telephony, television, and internet service in the country. Now, Germany's federal criminal police force (BKA) revealed today that the UK's National Crime Agency (NCA) reportedly arrested a 29-year-old British suspect at Luton airport in London on Wednesday, who is accused of being the mastermind behind the last year's attack. In a statement , the German police said the last year's attack was especially severe and was carried out to compromise the home routers to enroll them in a network of hijacked machines popularly known as Botnet, and then offer the DDoS services for sale on dark web markets. But ultimately, the attack created a denial-of-service situation, which resulted i...

SHA-1, Secure Hash Algorithm 1, a very popular cryptographic hashing function designed in 1995 by the NSA, is officially dead after a team of researchers from Google and the CWI Institute in Amsterdam announced today submitted the first ever successful SHA-1 collision attack. SHA-1 was designed in 1995 by the National Security Agency (NSA) as a part of the Digital Signature Algorithm. Like other hashes, SHA-1 also converts any input message to a long string of numbers and letters that serve as a cryptographic fingerprint for that particular message. Collision attacks appear when the same hash value (fingerprint) is produced for two different messages, which then can be exploited to forge digital signatures, allowing attackers to break communications encoded with SHA-1. The explanation is technologically tricky, but you can think of it as attackers who surgically alters their fingerprints in order to match yours, and then uses that to unlock your smartphone. The researchers h...

Another privilege-escalation vulnerability has been discovered in Linux kernel that dates back to 2005 and affects major distro of the Linux operating system, including Redhat, Debian, OpenSUSE, and Ubuntu. Over a decade old Linux Kernel bug ( CVE-2017-6074 ) has been discovered by security researcher Andrey Konovalov in the DCCP (Datagram Congestion Control Protocol) implementation using Syzkaller , a kernel fuzzing tool released by Google. The vulnerability is a use-after-free flaw in the way the Linux kernel's "DCCP protocol implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the IPV6_RECVPKTINFO option is set on the socket." The DCCP double-free vulnerability could allow a local unprivileged user to alter the Linux kernel memory, enabling them to cause a denial of service ( system crash ) or escalate privileges to gain administrative access on a system. "An attacker can control what object that would be and overwrite...

Next time when you accidentally or curiously land up on a website with jumbled content prompting you to download a missing font to read the blog by updating the Chrome font pack… …Just Don't Download and Install It. It's a Trap! Scammers and hackers are targeting Google Chrome users with this new hacking scam that's incredibly easy to fall for, prompting users to download a fake Google Chrome font pack update just to trick them into installing malware on their systems. Here's What the Scam is and How it works: It's a "The 'HoeflerText' font wasn't found" scam. Security firm NeoSmart Technologies recently identified the malicious campaign while browsing an unnamed WordPress website that had allegedly already been compromised, possibly due to failing to apply timely security updates.

Microsoft on Tuesday released security update (KB 4010250) to patch flaws in Adobe Flash Player for its customers using Internet Explorer on Windows 8.1 and later, as well as Edge for Windows 10, but two already disclosed flaws remain unpatched. Just last week, Microsoft announced that its February patches would be delayed until March due to a last minute issue, a move that led to Google publishing details of an unpatched Windows bug . However, the software giant emailed a handful of big business to alert them to the incoming patches on Monday, advising them to update their systems as soon as possible. The security patches are now available to all Windows customers over Windows Update, and " No other security updates are scheduled for release until the next scheduled monthly update release on March 14, 2017 ," Microsoft says. Bulletin MS17-005 for Adobe Flash Player addresses remote code execution (RCE) vulnerabilities for some currently supported Windows systems....
