Cyberattacks Target Civil Liberties Organizations

Avatar

on

Amid global protests of police brutality, internet traffic data indicates that hackers have started to launch cyberattacks on prominent civil rights advocacy organizations in the U.S.

Protests have erupted across the U.S. in the past two weeks over the death of George Floyd, an unarmed black man who was killed in police custody on Memorial Day.

The protests call for change in the policing system, as the use of deadly force to subdue and arrest unarmed citizens comes under increased scrutiny.

In this case, the Minneapolis Police Department officer held his knee on George Floyd’s neck for nearly nine minutes, all while Floyd repeatedly stated that he couldn’t breathe. Floyd became unconscious in the final minutes of the incident, after which he was taken to the hospital and pronounced dead.protestors image 2

The incident, which was recorded by bystanders on a smartphone, sparked demands for police reform under the #BlackLivesMatter movement.

As the protests have expanded globally and intensified across all U.S. states, cybercriminals have begun targeting civil liberties organizations more than usual.

Cloudflare has reported that hackers are increasing their level of attacks against organizations that support civil liberties.

The company, which provides cybersecurity and DNS protection services, collected statistics for the past view weeks and analyzed HTTP requests that were blocked in the time frame.

Cloudflare then compared that data to a corresponding period in April. In its report, Cloudflare stated that it had blocked more than 116 billion HTTP requests that tried to perform DDoS attacks or break into various APIs (application programming interfaces), apps and websites on April 25 and April 26.blocked http image

But when Cloudflare compared that to the number on May 30 and May 31 (corresponding to the weekend after Floyd’s death), it found that hackers had launched a whopping 135 billion HTTP requests. That amounts to around a 17% increase, month to month.

Not only that, but the security provider also found that on Sunday, May 31, hackers launched 26% more cyberattacks when compared to the Sunday of April one month earlier.

Cloudflare also studied the exact categories of websites and apps that hackers targeted in the latest round of attacks.

Researchers working at the firm found that the majority of the internet properties that hackers targeted belonged under the category of advocacy groups.

This organizational demographic marked the greatest increase in the number of attacks. Cloudflare reported that advocacy group websites suffered a 1,120x increase in the number of cyberattacks.cyberattack image 1

Matthew Prince, the current CEO of Cloudflare, along with CTO John Graham-Cumming, explained that the advocacy group category went from having no cyberattacks launched against them back in April, to suffering a peak attack number of 20,000 HTTP requests every second on just one of their websites.

In addition to that, the firm also noted that one of the hackers made use of a compromised server based in France and then spent the next 24 hours attacking a website belonging to the advocacy group category.

Note

Graham-Cumming and Prince also shared additional details regarding Cloudflare’s Project Galileo initiative, which seeks to provide cybersecurity solutions to vulnerable targets that might not have online security defenses in place to prevent attacks.

Vulnerable targets include political dissent groups along with humanitarian organizations.

Cloudflare reported that over the past few weeks, hackers have started targeting organizations participating in Project Galileo whose mission is to fight racism and pursue social justice for marginalized people.protestors image 4

The benefit of Project Galileo to nonprofits and advocacy organizations is that it provides cybersecurity solutions to groups that might not have a budget for mitigating cyber threats and preventing attacks.

For the moment, it appears that Black Lives Matter and the organizations that support it are under attack by an unknown group of hackers.

Hacktivists trying to provide support for the movement might also have to bear the brunt of this new wave DDoS cyberattacks against them.

Although, groups like Anonymous have started launching their own DDoS attacks for the cause. They’ve already taken down the Minneapolis Police Department website and posted a video on Facebook threatening to expose the agency’s history of corruption to the world.

Fintechs are ransomware targets. Here are 9 ways to prevent it.

Published

Cybercriminals are clever, and they often target fintechs for two reasons. They know fintechs handle a lot of sensitive and financial information on a daily basis, and that they probably have the means to meet hackers’ demands and get back to business as usual.

Ransomware attacks are one of the most common fintech cybersecurity risks, and falling victim to one can be devastating — or disruptive at the very least. So, we asked the experts at ESET to explain how to prevent ransomware, and secure your business from the inside out.

Firstly, what is ransomware and how does it work?

With a ransomware attack, a cybercriminal hacks into their victim’s systems and essentially holds their data “hostage” until they pay a ransom. Since hackers know how valuable data is to a business, they tend to set ransoms in the thousands or even millions of dollars.

There are two types of attacks: crypto ransomware encrypts all the files, folders and hard drives on the infected computer, while locker ransomware locks users out of their devices. For cybercriminals, the goal is to get you to pay up so you can retrieve your files and mitigate any damage to your business.

What to do after a ransomware attack

Unfortunately, you don’t have too many options if you fall victim to a ransomware attack. You’ll need to decide to pay the ransom or not, and that involves weighing up how much your data is worth. Just keep in mind that giving in to a cybercriminal’s demands may encourage them to attack you again — and there’s no guarantee that your data will be restored.

Either way, it’s important to go into disaster recovery mode right away. Follow these steps for what to do if you get ransomware:

1. Alert your IT department. If your company has IT professionals or a Chief Information Security Officer, notify them about the attack. Hopefully, they’ll have a plan of actions for situations like these and be able to guide your team through these steps.

2. Trace the source of the attack. Most ransomware attacks have a countdown clock before all your files are deleted forever, so the sooner you find the source, the faster you can act. Typically, ransomware sneaks its way into your system through a malicious link or email attachment. The best-case scenario is the ransomware only attacks that one device, and the worst-case is it infects your entire system. Once you’ve found the culprit, ask the user if they’ve opened other suspicious emails or noticed anything weird about their computer.

3. Remove that device from your network. To stop the ransomware from spreading through your network, you’ll need to unplug the infected device.

4. Let your employees and clients know about the breach. While it’s important not to cause panic, you do need to be transparent. The truth is, most cyber breaches are the result of human error, so your employees need to know what happened and what’s expected of them. As for your clients or customers, contact them if you have proof their data has been compromised. In other words, avoid putting out a statement until you have all the information.

5. Invest in better security systems. When you’ve gotten through the aftermath, look into more sophisticated cybersecurity in fintech practices.

9 ways to prevent ransomware attacks

Ransomware is incredibly common, and as you now know, there are limited ways to deal with an attack. You need to be proactive and prepared, and implement measures to prevent an attack.

As you might have guessed, fintech cybersecurity should be a priority. These are our tips for how to protect against ransomware: 

Set up sophisticated email filters. The majority of ransomware is delivered by spam or phishing emails. To stop ransomware before it has a chance to infect your systems, employ email filters that scan all email content for spam, viruses and other forms of malware.

Run regular security audits. It’s worth assessing your security systems to identify any gaps or weaknesses. If you can, consider outsourcing your cybersecurity, reallocating resources or hiring in-house professionals to give your fintech peace of mind.

Use an up-to-date antivirus and anti-ransomware software. To protect your company devices from ransomware, malware, identity theft and more, install a third-party antivirus software designed for businesses. ESET Digital Security for Business offers the best ransomware protection and defence against a range of advanced cyber threats, and can be tailored to the size and scope of your fintech. Along with blocking persistent threats, it secures your devices with endpoint protection, which is especially handy if you have employees who work remotely.

Accept all software updates. Cybersecurity companies often release new patches to fix bugs and address vulnerabilities, which is why it’s essential to stay on top of any updates. In other words, you could have the most sophisticated antivirus ransomware software in the world, but that won’t do you any good if you ignore every notification that pops up! Updates usually take a few minutes to download and require you to restart your computer, but they make your company much less vulnerable to ransomware.

Implement multi-factor authentication. Two-factor authentication is good, but multi-factor authentication is better. This means employees will need to enter their username, password and one more piece of additional information — usually a code sent to their phone or email — before they can log into the system. It also makes it harder for hackers to break in.

Create a whitelisting program. This is effective in preventing ransomware, and it involves restricting the applications that can run within your company’s system. Think of it as the opposite of blacklisting — only applications that have passed the approval process will work.

Encrypt your company files. Ideally, all of your data should be end-to-end encrypted, and access limited to the people who need that information to do their jobs. The good news is, most computers and phones have built-in operating systems that encrypt stored data and prevent unauthorised users.

Tighten your cloud security. Speaking of the cloud, some cloud services don’t offer secure encryption and can’t distinguish between authorised users and other people trying to access the cloud. ESET Cloud Office Security will configure your cloud security so hackers can’t bypass your company’s policies and tap into sensitive information.

Routinely back up your data and systems. By backing up your data regularly, you’ll be able to recover any lost or corrupted data if your server crashes or if you fall victim to a ransomware attack. We recommend always having two encrypted backups: one on the cloud, and one an external hard drive.

What are Insecure Direct Object References (IDOR)?

Avatar

Published

HackerOne Hacker Noon profile picture

@hacker0x01HackerOne

HackerOne empowers the world to build a safer internet.

Insecure Direct Object References (or IDOR) is a simple bug that packs a punch. When exploited, it can provide attackers with access to sensitive data or passwords or give them the ability to modify information. On HackerOne, over 200 are found and safely reported to customers every month. 

What is an IDOR?

There are several types of IDOR attacks, including:

  • Body Manipulation, in which attackers modify the value of a checkbox, radio buttons, APIs, and form fields to access information from other users with ease.
  • URL Tampering, in which the URL is modified at the client’s end by tweaking the parameters in the HTTP request. 
  • HTTP Requests in which IDOR vulnerabilities are typically found in GET, POST, PUT, and DELETE verbs.
  • Mass Assignment, where a record pattern can be abused to modify data that the user should not be able to access. While not always a result of IDOR vulnerabilities, there are many powerful examples of this being the result of it. 

In its simplest and most common form, an IDOR vulnerability arises when the only input required to access or replace content is from the user. This vulnerability submitted to Shopify by California-based hacker Rojan Rijal (a.k.a. @rijalrojan) in 2018 is the perfect example.

By observing how file attachments were labeled when sending a query to Shopify’s Exchange Marketplace application, Rojan was able to replace documents by leveraging the same file name from different accounts. 

Figure 1: IDOR vulnerability reported by @rijalrojan to Shopify on the HackerOne platform.

For retail and ecommerce companies, IDOR vulnerabilities represent 15% of what organizations pay bounties for and represent the top vulnerability for programs across government (18%), medical technology (36%), and professional services (31%) industries. 

If they’re so simple, why are they so common? 

In short, IDORs can not be detected by tools alone. 

IDORs require creativity and manual security testing to identify them. They require you to understand the business context of the target application. While some scanners might detect activity, it takes a human eye to analyze, evaluate, and interpret. Understanding the deeper context is an innately human skill that machines cannot replicate. In traditional pentests, unless a pentester tests every possible parameter in every request endpoint, these vulnerabilities can go undetected. 

What are the implications of an IDOR vulnerability? 

Perhaps the most infamous IDOR vulnerability as of late is that found in alt-tech social media platform Parler. The company ordered their posts by number in the URL, a telltale sign of IDOR. If you add a sequential digit to a Parler post URL, you could access the next post on the platform indefinitely. Without authentication or access limits, an attacker could easily build a program to download every post, photo, video, and data from the entire site. While this was just public posts (not necessarily IDs used to verify accounts), geolocation data from posts was also downloaded, which could reveal GPS coordinates of users’ homes.  

How can you prevent IDORs from cropping up?

“Avoiding IDOR is only possible by building a robust access control mechanism, choosing the best fit methodology for your scenario, log all access and if possible do an audit with a post authorization check,” said HackerOne hacker Manoel Abreu Netto, better known online as @manoelt.

“However, if you want to reduce the impact of an IDOR, avoid using a simple pattern to reference objects in the backend, thus not using a sequential integer value but something like uuid or even a MAC (hashed ID) with a salt per user session.

This does not eliminate the IDOR, but reduces the overall impact and the ability to enumerate objects.”

To remediate IDOR vulnerabilities, below are a few best practices. 

  1. Developers should avoid displaying private object references such as keys or file names.
  2. Validation of parameters should be properly implemented.
  3. Verification of all the referenced objects should be checked.
  4. Tokens should be generated in such a way that it can only be mapped to the user and is not public.
  5. Ensure that queries are scoped to the owner of the resource. 
  6. Avoid things like using UUIDs (Universally unique identifier) over Sequential IDs as UUIDs often let IDOR vulnerabilities go undetected.
