Amazon Web Services (AWS), Cloudflare, and Google on Tuesday said they took steps to mitigate record-breaking distributed denial-of-service (DDoS) attacks that relied on a novel technique called HTTP/2 Rapid Reset. The  layer 7 attacks  were detected in late August 2023, the companies said in a coordinated disclosure. The cumulative susceptibility to this attack is being tracked as  CVE-2023-44487 , and carries a CVSS score of 7.5 out of a maximum of 10. While the attacks aimed at Google's cloud infrastructure peaked at  398 million requests per second  (RPS), the ones that struck AWS and Cloudflare exceeded a volume of 155 million and 201 million RPS, respectively. HTTP/2 Rapid Reset refers to a zero-day flaw in the HTTP/2 protocol that can be exploited to carry out DDoS attacks. A significant feature of HTTP/2 is multiplexing requests over a single TCP connection, which manifests in the form of concurrent streams. What's more, a client that wants to abort a request can

GitHub has  announced  an improvement to its secret scanning feature that extends validity checks to popular services such as Amazon Web Services (AWS), Microsoft, Google, and Slack. Validity checks,  introduced  by the Microsoft subsidiary earlier this year, alert users whether exposed tokens found by  secret scanning  are active, thereby allowing for effective remediation measures. It was first enabled for GitHub tokens. The cloud-based code hosting and version control service said it intends to support more tokens in the future. To toggle the setting, enterprise or organization owners and repository administrators can head to Settings > Code security and analysis > Secret scanning and check the option "Automatically verify if a secret is valid by sending it to the relevant partner." Earlier this year, GitHub also  expanded  secret scanning alerts for all public repositories and announced the  availability of push protection  to help developers and maintainers pr

Cloud environments continue to be at the receiving end of an ongoing advanced attack campaign dubbed SCARLETEEL, with the threat actors now setting their sights on Amazon Web Services (AWS) Fargate. "Cloud environments are still their primary target, but the tools and techniques used have adapted to bypass new security measures, along with a more resilient and stealthy command and control architecture," Sysdig security researcher Alessandro Brucato said in a new report shared with The Hacker News. SCARLETEEL was  first exposed  by the cybersecurity company in February 2023, detailing a sophisticated attack chain that culminated in the theft of proprietary data from AWS infrastructure and the deployment of cryptocurrency miners to profit off the compromised systems' resources illegally. A follow-up analysis by Cado Security  uncovered  potential links to a prolific cryptojacking group known as  TeamTNT , although Sysdig told The Hacker News that it "could be some

An updated version of the commodity malware called Legion comes with expanded features to compromise SSH servers and Amazon Web Services (AWS) credentials associated with DynamoDB and CloudWatch. "This recent update demonstrates a widening of scope, with new capabilities such the ability to compromise SSH servers and retrieve additional AWS-specific credentials from Laravel web applications," Cado Labs researcher Matt Muir  said  in a report shared with The Hacker News. "It's clear that the developer's targeting of cloud services is advancing with each iteration." Legion, a Python-based hack tool, was  first documented  last month by the cloud security firm, detailing its ability to breach vulnerable SMTP servers in order to harvest credentials. It's also known to exploit web servers running content management systems (CMS), leverage Telegram as a data exfiltration point, and send spam SMS messages to a list of dynamically-generated U.S. mobile num

A new attack method can be used to circumvent web application firewalls (WAFs) of various vendors and infiltrate systems, potentially enabling attackers to gain access to sensitive business and customer information. Web application firewalls are a  key line of defense  to help filter, monitor, and block HTTP(S) traffic to and from a web application, and safeguard against attacks such as cross-site forgery, cross-site-scripting (XSS), file inclusion, and SQL injection (SQLi). The generic bypass "involves appending  JSON syntax  to SQL injection payloads that a WAF is unable to parse," Claroty researcher Noam Moshe  said . "Most WAFs will easily detect SQLi attacks, but prepending JSON to SQL syntax left the WAF blind to these attacks." The industrial and IoT cybersecurity company said its technique successfully worked against WAFs from vendors like Amazon Web Services (AWS), Cloudflare, F5, Imperva, and Palo Alto Networks, all of whom have since released updates

Amazon Web Services (AWS) has resolved a cross-tenant vulnerability in its platform that could be weaponized by an attacker to gain unauthorized access to resources. The issue relates to a  confused deputy problem , a type of privilege escalation where a program that doesn't have permission to perform an action can coerce a more-privileged entity to perform the action. The shortcoming was reported by Datadog to AWS on September 1, 2022, following which a patch was shipped on September 6. "This attack abuses the AppSync service to assume [identity and access management]  roles  in other AWS accounts, which allows an attacker to pivot into a victim organization and access resources in those accounts," Datadog researcher Nick Frichette  said  in a report published last week. In a coordinated disclosure, Amazon  said  that no customers were affected by the vulnerability and that no customer action is required. It described it as a "case-sensitivity parsing issue w

Want to take advantage of excellent cloud services? Amazon Web Services may be the perfect solution, but don't forget about AWS security. Whether you want to use AWS for a few things or everything, you need to protect access to it. Then you can make sure your business can run smoothly. Read on to learn some important AWS security tips. Use Multi-Factor authentication When setting up your AWS security settings or adding new users, you should implement multi-factor authentication (MFA). MFA relies on more than one login factor to grant you access to your account. For example, when you log in to your account, the program might send a code to your mobile phone. Then you must verify that you have that phone and enter the code to access your account. MFA is an excellent way to protect your data if someone figures out your username and password. This way, you can still have a layer of protection against the hacker. Create strong passwords Even with MFA, you should use strong, uni

Magecart strikes again! Cybersecurity researchers have identified yet another supply-chain attack carried out by payment card hackers against more than 17,000 web domains, which also include websites in the top 2,000 of Alexa rankings. Since Magecart is neither a single group nor a specific malware instead an umbrella term given to all those cyber criminal groups and individuals who inject digital card skimmers on compromised websites, it is not necessary for every one of them to use similar techniques with the same sophistication. A new report shared with The Hacker News prior to its release details a new supply-chain attack campaign wherein hackers are using shotgun approach instead of targeted attacks to infect a wide range of websites, preferring larger infection reach as possible over accuracy. Almost two months ago, security researchers from RiskIQ discovered supply-chain attacks involving credit card skimmers placed on several web-based suppliers, including AdMaxi

A security researcher has discovered several critical vulnerabilities in one of the most popular embedded real-time operating systems—called FreeRTOS—and its other variants, exposing a wide range of IoT devices and critical infrastructure systems to hackers. What is FreeRTOS (Amazon, WHIS OpenRTOS, SafeRTOS)? FreeRTOS is a leading open source real-time operating system (RTOS) for embedded systems that has been ported to over 40 microcontrollers, which are being used in IoT, aerospace, medical, automotive industries, and more. RTOS has specifically been designed to carefully run applications with very precise timing and a high degree of reliability, every time. A pacemaker is an excellent example of the real-time embedded system that contracts heart muscle at the right time, a process that can't afford delays, to keep a person alive. Since late last year, FreeRTOS project is being managed by Amazon, who created Amazon FreeRTOS (a:FreeRTOS) IoT operating system for mic

Viacom—the popular entertainment and media company that owns Paramount Pictures, Comedy Central, MTV, and hundreds of other properties—has exposed the keys to its kingdom on an unsecured Amazon S3 server. A security researcher working for California-based cyber resiliency firm UpGuard has recently discovered a wide-open, public-facing misconfigured Amazon Web Server S3 cloud storage bucket containing roughly a gigabyte's worth of credentials and configuration files for the backend of dozens of Viacom properties. These exposed credentials discovered by UpGuard researcher Chris Vickery would have been enough for hackers to take down Viacom's internal IT infrastructure and internet presence, allowing them to access cloud servers belonging to MTV, Paramount Pictures and Nickelodeon. Among the data exposed in the leak was Viacom's master key to its Amazon Web Services account, and the credentials required to build and maintain Viacom servers across its many subsidiarie

Verizon, the major telecommunications provider, has suffered a data security breach with over 14 million US customers' personal details exposed on the Internet after NICE Systems , a third-party vendor, mistakenly left the sensitive users' details open on a server. Chris Vickery, researcher and director of cyber risk research at security firm UpGuard, discovered the exposed data on an unprotected Amazon S3 cloud server that was fully downloadable and configured to allow public access. The exposed data includes sensitive information of millions of customers, including their names, phone numbers, and account PINs (personal identification numbers), which is enough for anyone to access an individual's account, even if the account is protected by two-factor authentication . "The exposure of Verizon account PIN codes used to verify customers, listed alongside their associated phone numbers, is particularly concerning," explained UpGuard's Dan O'Sullivan in

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

With providing easy accessibility, the battle is not won! Server-side Vulnerabilities have been reported by a security researcher in the popular Pocket add-on that comes attached with the Firefox browser. The security flaws could have allowed hackers to exfiltrate data from the company's servers as well as populate reading lists with malicious links. The Pocket button in the Firefox browser allows you to save links, videos, web pages, or articles to your Pocket account with just a click, making it easier for you to read them later, usually offline. However, the vulnerabilities discovered by security researcher Clint Ruoho was such that it could allow hackers to get an unrestricted root access to the server hosting the application, the researcher wrote in his blog post . For this to be done, a hacker only needs: A browser The Pocket Mobile app Access to an Amazon EC2 Server which costs 2 cents an hour The researcher, with the goal of exploiting the service's main functionality

Security in the Amazon EC2 environment is a responsibility shared by both the end user and Amazon. This is because within this environment there are specific parts that Amazon has control of and specific parts that are controlled by the end user. For the end user, they are responsible for securing the operating systems running on their instances, as well as the applications running on those operating systems. On the other hand, physical security and security of the hypervisor is Amazon's responsibility. When it comes to the network, security of that layer is a shared responsibility between the user and Amazon. Implications of the Shared Security Model Huge operational efficiencies can be gained in a shared security model, however this comes at the cost of the flexibility to have total control over an environment. In the past, significant security issues have occurred as organizations move to the shared model. During this transition, it's key that organizations under

" The Interview ", the controversial North Korean-baiting film which appeared to be the root cause of the cyber mishap occurred at Sony Pictures Entertainment that threatened terror attack at theaters showing the movie, now threatens to expose users of Android phones to a malware attack. Since its release, everyone is talking about "The Interview" — the Seth Rogen and James Franco-starring comedy centered around a TV host and his producer assassinating North Korean dictator Kim Jong Un. Because cybercriminals are known to take advantage of major events where there is a high level of public interest, The Interview became their target. In a joint investigation, Security researchers of McAfee and Technische Universität Darmstadt and the Center for Advanced Security Research Darmstadt (CASED) has discovered an Android app claiming to download 'The Interview' comedy on their smartphone devices actually infects users' devices with banking trojan in
