Credential Stuffing Attacks: How to Protect Yourself

GLOBAL INTERNET USERE 2020

 

As we look forward to the hopefully great year ahead, let’s rewind a year that seems to have more episodes than Game of Thrones. Companies all across the globe were put into a huge test followed by a rapid shift from office working to home-office prompted by the coronavirus pandemic. Nearly overnight, organizations worldwide had to enable remote workforces to support their business requirements. COVID-19 has in many ways unleashed a new set of challenges and/or accelerated existing challenges, such as ransomware, data breaches, API attacks, cyber-fraud and unemployment frauds, within global enterprises.

 

It’s clear-cut that technology and security teams struggled in 2020 to respond as quickly to the changing environment as did the cybercriminals, who took advantage of an environment of unexpected change, extraordinary shifts in employees’ working process, and technology used by governments and worldwide companies.

 

Akamai reports that global internet traffic has grown by as much as 30 percent in 2020, while Statista observed that only in October 2020, online traffic across 20 different industries increased by 1.5% compared to the reference period in January 2020. Online transactions increased by 26.7 % compared to 2019. Another report from Cisco predicted there will be 5.3 billion total Internet users (66 percent of the global population) by 2023, up from 3.9 billion (51 percent of the global population) in 2018. That’s nearly two-thirds of the global population with Internet access.

 

The internet has gained more popularity in 2020, internet users are currently growing at an annualized rate of more than 7%, equating to an average of more than 875,000 new users each day. With this massive increase in the global internet traffic, Akamai is seeing over a hundred million of these attacks every day, with a peak of nearly 300 million a day, only in its own customer base. On the one hand, the internet is serving humanity, on the other hand, it has become the best place of like phishing, fraud, identity theft, Email Spoofing, bullying, cyberstalking, Malware, computer viruses.

 

In the history of cybercrime, the global coronavirus pandemic has added the credential stuffing problem to it extend. For those who don’t know, in this attack method, a cybercriminal tries a large number of stolen credentials on multiple websites. In order to gain unauthorized access to as many user accounts as possible to carry out attacks or fraudulent activities.

 

Transactional bots are getting popularity among hackers, as they act as agents on behalf of hackers. Bots aren’t typically created to compromise just one individual computer, they’re designed to infect millions of devices. An attacker first identifies websites with valuable accounts such as credit institutions, online shops, etc. In the Darknet, he then acquires lists of stolen login data and rents a botnet to automatically check the account list on the advised website. If a credential stuffing attack is successful, the attacker either sells the new, validated access data in the darknet or uses it himself. With the stolen data, fraudsters can then, for example, log into third-party accounts and carry out financial transactions.

 

Attacks like these often have very unpleasant consequences for the concerned companies and institutions, Application failures due to impaired web performance (73%) and recovery costs (63%) are among the greatest burdens, but also lower customer satisfaction, lost sales and financial losses (all-around 40%) have a significant weight (Akamai).

 

Here below are the few possible ways to protect yourself against credential stuffing attacks.

Protecting yourself from credential stuffing is pretty simple if you use the same password security tips that security experts have been recommending for years. For effective protection against bot attacks, it is recommended in the first step not to reuse the passwords, use a password manager, enable two-factor authentication, and get your leaked password notifications.

 

By using a unique password for each online account, you can protect all of your accounts at once. Because even if one of your passwords gets leaked, it can’t be used to sign in to other websites. As remembering strong unique passwords, for each account you have, is a nearly impossible task, the use of a password manager is recommended. It can not only remember your passwords but also generate strong unique passwords. Additionally, don’t ignore the 2-factor authentication. It is much more difficult to hack your account if you’re using two-factor authentication on it. As it adds an additional layer of security to the authentication process, it harder for attackers to gain access to your devices or online accounts.

CISCO: Cloud networking trends

Essential characteristics of cloud

The annual Cisco Global Cloud Index (2016-2021) shows that data-center traffic is growing rapidly due to increasingly-used cloud applications. According to the study, global cloud traffic will reach 19.5 zettabytes (ZB) in 2021. This is an increase of 6.0 ZB compared to 2016, which is 3.3 times higher, with an annual growth rate of 27%. In three years, cloud traffic will account for 95 % of total traffic, compared to 88 % in 2016.

According to the study, both B2C and B2B applications contribute to the growth of cloud services. For consumers, video streams, social networking, and web search are among the most popular cloud-based apps. For employees, it’s ERP, collaboration and analysis solutions.

 

Security and IoT as a growth driver

Increasing IoT applications, such as smart cars, smart cities, connected healthcare and digital care, require a highly scalable server and storage solutions to meet new and expanded data center needs. In 2021, there will be 13.7 billion IoT connections, compared to 5.8 billion in 2016, the study said.

In the past, security concerns were a major barrier to cloud usage. Improvements in data center control and data control reduce the risk to businesses and better protect customer information. New security features coupled with tangible benefits from cloud computing, such as scalability and efficiency, play an important role in cloud growth.

 

Hyperscale Datacenters Growth

The increasing demand for data center and cloud capacity has led to the development of hyper-scaled public clouds based on Hyper-scale data centers. The study predicts that there will be 628hyper-scale data centers worldwide in 2021, compared to 338 in 2016, nearly the double. In three years Hyperscale data centers will have:

  • 53 % of all data center servers (2016: 27 %)
  • 69 % of the computing power of data centers (2016: 41 %)
  • 65 % of data center data stored (2016: 51 %)
  • 55 % of all datacenter traffic (2016: 39 %)

The growth of data center applications is exploding in this new multi-cloud world. The predicted increase requires further innovation, especially in the public, private and hybrid cloud sectors.

 

Virtualization of data centers and cloud computing growth

By 2021, 94 % of the workloads and server will be processed in cloud data centers, the remaining 6 % in traditional data centers. All data center workloads and server instances will more than double (2.3x) between 2016 and 2021, while cloud-based workloads and server instances will almost triple (2.7x) over the same period).

The density of workloads and server instances in cloud data centers was 8.8 in 2016, rising to 13.2 by 2021. In traditional data centers, density increases from 2.4 to 3.8 over the same period.

 

Big Data and IoT fuel data explosion

Worldwide, the amount of data stored in data centers will increase almost fivefold, from 286 Exabytes in 2016 to 1.3 ZB 2021 (4.6x, with annual growth of 36%). Big data will grow almost 8x, from 25 to 403 EB. In 2021, it will contain 30 % of all data stored in data centers compared to 18 % in 2016.

The amount of stored data in devices in 2021 will be 4.5 times higher at 5.9 ZB than data stored in data centers. Mainly due to the IoT, the total amount of generated data (which will not necessarily be saved) will reach 847 eg by 2021, in 2016 it was 218 eg. This generates more than 100 times more data than saved.

 

Applications contribute to data growth

By 2021, Big Data will account for 20% (2.5 ZB annually, 209 EB monthly) of data center traffic, compared to 12 % (593 EB annually, 49 EB monthly) in 2016, video streaming will account for 10 % of data center traffic, compared to 9 % in 2016. Video will account for 85 % of data center traffic to users, compared to 78 % in 2016, internet search will account for 20 % of data center traffic, compared to 28 % in 2016, social networks will account for 22 % of data center traffic, compared to 20 % in 2016.

 

SaaS is the most popular cloud service model by 2021

By 2021, 75 % (402 millions) of all cloud workloads and server instances will be SaaS-based, compared to 71 % (141 million) in 2016 (which represents 23 % of annual growth).

16 % (85 millions) of all cloud workloads and server instances will be IaaS-based, compared to 21 % (42 million) in 2016 (which represents 15 % annual growth).

9 % (46 millions) of all cloud workloads and server instances will be PaaS-based, compared to 8 % (16 million) in 2016 (which represents 23% annual growth rate).

 

As part of the study, cloud computing includes platforms that provide continuous, on-demand network access to configurable resources (e.g., networks, servers, storage, applications, and services). These can be quickly deployed and shared with minimal management effort or interactions with service providers. Deployment models include Private, Public, and Hybrid Clouds. Cloud data centers can be operated by both service providers and private companies.

 

The key differences between cloud data centers and traditional data centers are virtualization, standardization, automation, and security. Cloud data centers offer higher performance, higher capacity, and easier management compared to traditional data centers. Virtualization serves as promoter for the consolidation of hardware and software, greater automation and an integrated approach to security.
