Cloud Misconfiguration is Still the Leading Source of Cloud Data Violations

 

Almost everybody by now is workings from home and 84 percent are worried that new security vulnerabilities have been generated with the quick move towards 100 percent remote working. 

Cloud service providers built their administration panels' user interface purposefully to mislead consumers and charge for more services than originally intended. 

Although it was never demonstrated as a systematic business strategy, reports and alerts of a data breach have overwhelmed the internet in recent years since a cloud-based database has indeed been misconfigured and confidential information ultimately leaked. 

Throughout the past month, Censys, a security company that specializes in census-like inspections on the internet, looked closely at the cloud-based services, hoping to uncover what the best potential origin of misconfiguration might be for cloud-based businesses. As per the study, Censys has found over 1.93 million cloud server databases that have been displayed publicly without even any firewall or other authentication measures. The security company arguments that threat actors will discover and target these databases utilizing older vulnerability exploits. In addition, if the database was unintentionally leaked, it could also use a weak or even no password at all, disclosing it to all those who have detected its IP address. 

Censys reported having been used to scan MySQL, Postgres, Redis, MSSQL, MongoDB, Elasticsearch, Memcached, and Oracle and that nearly 60 percent of all disclosed servers were MySQL databases which represent 1.15 million of the 1.93 million overall exposed DBs. 

The security agency also searched to find ports that could also be exposed by clouds service as they are normally used for remote management applications like SSH, RDP, VNC, SMB, Telnet, Team Viewer, and PC Anywhere. Censys retained that access to all these remote managing port must not be easily discovered but rather secured by Access Control Lists, VPN tunnel, or other traffic filtering solutions, although the underlying cause of these applications is that the systems can be remotely logged into. 

Another very significant discovery was indeed the virtual exposure of the RDP login screens by more than 1.93 million servers. 

Microsoft and several others have also indicated that many violations of security have also been caused by attackers obtaining access to an enterprise through compromised RDP credentials. Which included attacks on a broad range of actors, including DDoS botnets, crypto mining activities, ransomware gangs, and government-funded actors. 

Most organizations do not operate internally with just one cloud services provider infrastructure, but instead use several solutions, many of which might not have the same access or default settings, allowing several systems to become accessible even though IT personnel are not supposed to do so. While some cloud providers have taken measures to improve their dashboards and to clarify how those controls operate, the wording of each cloud provider is still substantially different, and some system administrators are still often confused. 

Censys said, “it expects the issue of misconfigured services to remain a big problem for companies going forward.”

A resurgence in DDoS Attacks amidst Global COVID-19 lockdowns


Findings of Link11's Security Operations Center (LSOC) uncovered a 97% increase in the number of attacks for the months of April, May, and June in 2020 when compared with the attacks during the same period in the previous year, with an increment of 108% in May 2020.

The annual report incorporates the data which indicated that the recurrence of DDoS attacks relied upon the day of the week and time, with most attacks concentrated around weekends of the week and evenings. 

More attacks were registered on Saturdays, and out of office hours on weekdays. 

Marc Wilczek, COO, Link11 says, “The pandemic has forced organizations to accelerate their digital transformation plans, but has also increased the attack surface for hackers and criminals – and they are looking to take full advantage of this opportunity by taking critical systems offline to cause maximum disruption. This ‘new normal’ will continue to represent a major security risk for many companies, and there is still a lot of work to do to secure networks and systems against the volume attacks. Organizations need to invest in security solutions based on automation, AI, and Machine Learning that are designed to tackle multi-vector attacks and networked security mechanisms...” 


Key findings from the annual report include: 

Multivector attacks on the rise: 52% of attacks consisted of a few strategies for the attack, making them harder to defend against. One attack included at least 14 techniques.

The growing number of reflection amplification vectors:: More usually utilized vectors included DNS, CLDAP, and NTP, while WS Discovery and Apple Remote Control are still being utilized in the wake of being discovered in 2019. 

DDoS sources for reflection amplification attacks distributed around the globe: The top three most significant source nations in H1 2020 were the USA, China, and Russia. Be that as it may, the ever-increasing number of attacks have been traced back to France. 

The average attack bandwidth remains high: The attack volume of DDoS attacks has balanced out at a relatively elevated level, at an average of 4.1 Gbps. In most attacks, 80% were up to 5 Gbps. The biggest DDoS attack was halted at 406 Gbps. 

DDoS attacks from the cloud: At 47%, the percentage of DDoS attacks from the cloud was higher than the entire year 2019 (45%). Instances from every single established provider were 'misused', however, the more usual ones were Microsoft Azure, AWS, and Google Cloud. 

The longest DDoS attack lasted 1,390 minutes – 23 hours and interval attacks, which are set like little pinpricks and flourish on repetition lasted an average of 13 minutes.


BGP Hijacking Attacks Google, Amazon and Other Famous Networks’ Traffic!


As per reports, a telecommunication provider that is owned by Russia rerouted traffic which was intended for the most imminent Content Delivery Networks (CDNs) and cloud host providers of the globe.

The entire re-direction kept on for around an hour during which it affected over 8,500 traffic routes of the internet. The concerned organizations happen to be few of the most celebrated ones.

Per sources, the brands range across well-known names like Cloudflare, Digital Ocean, Linode, Google, Joyent, Facebook, LeaseWeb, Amazon, GoDaddy, and Hetzner.

Reportedly, all the signs of this attack indicate towards its being a case of hijacking the Border Gateway Protocol, also known as, BGP hijacking. It is the illegitimate takeover of IP prefixes by a hijacker to redirect traffic.

This gives a lot of power in the hands of the hijacker because they could at any time “publish an announcement” stating that the servers of a particular company are on their network. As a result of which all of e.g. Amazon’s traffic would end up on the hijacker’s servers.

In earlier times when Hypertext Transfer Protocol wasn’t as widely used to encrypt traffic, BGP hijacking was a lucrative way to carry Man-in-the-Middle (MitM) attacks and catch and modify traffic.

But in recent times, analysis and decryption of traffic later in time has become easier because of BGP hijacking, as the encryption gets weaker with time.

This predicament isn’t of a new kind. It has been troubling the cyber-world for a couple of decades, mainly because they aim at boosting the BGP’s security. Despite working on several projects there hasn’t been much advancement in improving the protocol to face them.

Google’s network has been a victim of BGP hijacking by a Nigerian entity before. Researchers mention that it is not necessary for a BGP hijacking to be malicious.

Reportedly, “mistyping the ASN” (Autonomous System Number) is one of the other main reasons behind a BGP hijacking, as it is the code via which internet units are recognized and ends up accidentally redirecting traffic.

Per sources, China Telecom stands among the top entities that have committed BGP hijacking, not so “accidentally”. Another famous one on a similar front is “Rostelecom”.

The last time Rostelecom seized a lot of attention was when the most gigantic of financial players were victimized by BGP hijacking including HSBC, Visa, and MasterCard to name a few.

The last time, BGPMon didn’t have much to say however this time, Russian Telecom is in a questionable state, per sources. They also mention that it is possible for the hijack to have occurred following the accidental exposure of the wrong BGP network by an internal Rostelecom traffic shaping system.

Things took a steep turn when reportedly, Rostelecom’s upstream providers re-publicized the freshly declared BGP routes all across the web aggravating the hijack massively.

Per researchers, it is quite a difficult task to say for sure if a BGP hijacking was intentional of accidental. All that could be said is that the parties involved in the hijack make the situation suspicious.

benefits of cloud computing

I have been managing in house Linux, mac and Windows servers for various clients for years . different clients need different features with low cost .

 

After introducing myself into the world of Cloud Storage , I am doing SaaS and cloud storage effectively. I prefer doing cloud storage in local geographic locations as it becomes hard to get initial data of 500GB offsite.

these are the benefits of cloud computing i have found

  • Maintain easy access to your information with minimal upfront cost. Pay as you go (monthly or yearly), based on demand.
  • There’s no need to spend big money on hardware, data center, software or licensing fees.
  • Stretch and grow without the need to buy expensive software licenses or programs. (normal cloud SaaS license is something like 1-5 users)
  • You can change direction without serious “people” or “financial” issues at stake. – that improve flexibility
  • You have access anytime, anywhere, making your life so much easier! (as long as you are online)
  • increase volume output or productivity with fewer people. Your cost per unit or project
  • Software updates and renewals are also handled by the cloud vendor and occur several times a year at no cost to the customer.
  • on-premise solutions require 2-3 years to implement but cloud solution will only take 2-3 months.  Not only is implementation time reduced, but the IT resources required to roll-out cloud solutions are much less.
  • With cloud deployments, capacity and location planning are no longer in the hands of the customer, but are the responsibility of the cloud vendor.  This allows companies to respond quickly to any business changes that may arise unexpectedly
  • SECURITY: One of the top concerns of cloud skeptics is the fear of sacrificing data security when allowing company data to exist outside the internal firewall. well with proper Encryption methods, user policies and regular security audits.  So no more worrying about lost laptops with confidential data and hacking threats.
  • Since all your data is stored in the cloud, backing it up and restoring the same is relatively much easier than storing the same on a physical device.
