Botnet Attack

Everything You Want to Know About a Botnet Attack


It is no secret that botnet attack have become significant security threats but what are they, exactly?

What is a Botnet Attack?

A botnet attack is performed by hackers using a collection of malware-infected devices, often termed as “zombies,” which are being controlled by the attackers. We often think of servers and computers being used in such an attack but increasingly, IoT devices like cameras, thermostats and more can help form botnet clusters.

Threat actors gain access to a device by using particular viruses to weaken the computer’s security system before executing “command and control software” to let them conduct their malicious activities on a large scale.

These activities can be automated to carry out countless simultaneous attacks, paralyzing infected devices for ransom or damage while also disguising their identity via the vast botnet network.

A botnet is used in many cybercrimes such as exploiting and making a financial gain, malware propagation, or just general disturbance of the Internet.

Botnet attacks are launched in many ways, including:

  • Spam Emails

The spamming process can be conducted by posing bots as a content server while others as SMTP servers. A spam campaign includes message templates, a senders list, and a recipient list.

  • Launching a DDOS Attack:

A Distributed Denial of Service Attack (DDoS) is another type of botnet attack launched on a website, company or government. This is conducted by sending many requests for content that overwhelms and shuts down the targeted server or website.

  • Ad Fraud

Cybercriminals can utilize the combined processing power of botnets to run fraudulent advertising schemes to attract clicks to get a percentage of ad fees.

  • Distributing Spyware, Malware, and Ransomware

Botnet attacks are also conducted to distribute spyware, ransomware, and malware.

  • Selling and Renting:

Believe it or not, botnets can be found for sale on the dark web to other cybercriminals to exploit!

HOW TO PREVENT BOTNET ATTACKS?

1. Emphasize Cybersecurity Education

For companies of all sizes, training their people is key. Employees should be trained to report unauthorized emails to the IT team, how to spot phishing emails, not to use public WiFi without using a VPN and more.

2. Keep All Software Up-to-Date

Software patches should always be applied promptly – beyond your browser and operating system, don’t forget to update antivirus protection, too!

3. Spam Filtering:

Email filtering solutions should be enabled to prevent most malicious messages from getting into the email inboxes. The more messages that are blocked, the less risk there is of your staff interacting with a phishing email.

4. Avoid Downloads from File Sharing Networks and P2P

Botnets regularly capitalize on P2P networks and file-sharing services to exploit company networks. Make sure all files are downloaded only from trusted sources and they’re scanned before and after downloading.

5. Control Access

Use multi-factor, risk-based authentication and other safe practices for access controls to prevent a successful botnet invasion on one machine from affecting the entire network.

What is Dark Web Scanning? Why It Is Important?


Why Dark Web Scanning is So Vital & Affordable?

Are your employees’ credentials – their email addresses and passwords – for sale on the dark web? With a thorough dark web scan by a trusted provider, you can find out.

Because it is often misunderstood, let’s first define exactly what is the dark web.

Essentially, the internet has 3 layers, two of which are used harmlessly every day. The surface web consists of all the websites most users visit daily — the public sites crawled, indexed and rendered easily by common search engines like Google and Bing.

The deep web, level two, is another safe layer comprised of unindexed databases not crawled by search engines, sites like browser-based email accounts or registration-required forums. The deep web is massive, comprising approximately 95% of all internet content.

The third layer, the dark web, is the one we all need to worry about and here’s why: it’s the playground of the lawless.

Dark Web Scan

It frankly doesn’t matter that the dark makes up only a tiny slice of the internet (less than a fraction of 1%), that it can only be reached through a special browser like TOR (The Onion Router) most people have never used or that up to 75% of dark web sites are actually inactive.

What matters is the fact that more than half of all active dark web sites are used for criminal activities. Thus, when a hacker manages to build a list of stolen credentials, the dark web is where he goes to sell that information.

If most internet users never visit the dark web, how can an organization know any if any of its employees’ credentials have been stolen?

Only by using a service like Dark Web ID from Cynexlink can a company discover if any of its user/password combinations can be found online – and if they’re part of the 80,000 new compromises exposed daily.

Importance of Dark Web Scanning?

  • Compromised credentials are used to conduct further criminal activity
  • 60% of employees use the same password for all services such as network login, social media and SaaS business applications, exponentially increasing the potential damage from a single compromised credential – even one that does not originate from within a company network
  • Over 75% of compromised credentials are discovered after the fact – either at the time of breach or when reported to the victim’s organization by law enforcement
  • Size does NOT matter: 43% of online attacks are aimed at small businesses and nearly 70% of SMBs experienced cyber attacks in 2018.
  • Once breached, 70% of companies with fewer than 250 employees were forced offline for a period of time, 37% experienced measurable financial loss and fully 10% were forced out of business altogether

Because over 80% of breaches begin with stolen credentials, real-time monitoring is a vital layer of protection. The good news is this: live, ongoing dark web scanning is a very inexpensive solution that even the smallest companies can afford.

Even better news: we’ll help make it even more affordable by offering one free scan with up to 100 exposed records so you can learn right away if any of your company’s credentials have been compromised.

5 Most Ignored Signs of a Malicious Bot ATTACK!


According to a 2017 survey, bot traffic has surpassed human traffic on the Internet.

What is Modern botnet and why they are dangerous?

Modern botnet

The modern botnet is one of the sophisticated cybercrime techniques. A botnet is a collection of internet-connected devices infected by malware that lets cybercriminals control them. The botnet attack is commonly used to get unauthorized access, data theft, DDoS attacks, and credentials leak.

Because of their complicated size and the challenges involved in detecting them, botnets can be operated secretly so that victims can’t sense them. Some software updates are also bots. Simply put, our digital technologies are surrounded by unavoidable bots.

But that doesn’t mean your network is destined to be attacked by bots. You can protect your network by identifying these malicious robots and you don’t have to be a skilled data scientist.

So How to Identify Malicious bots on your network?

All you need to do is follow the steps given below.

  • Keep an Eye on the Uniformity of Communications:

First, try to distinguish between bots (both bad and good) and humans. You can do this by identifying those machines that continuously communicates with a victim.

Bots communicate with their targets because they require commands, signals, and data. You need to find out the hosts that stay in touch with their targets periodically and continuously. Weekly traffic is sufficient to figure out client-target communication. Uniform communications are likely to be generated by a bot.

  • The Rate of Failed Login Attempts is Quite High:

One of the popular uses of bots is to steal passwords—a practice that is also known as ATO attack. A botnet will try to take control of user accounts by testing user-password combinations obtained from other sites. This way, botnets might attempt to legalize millions of accounts per day. If you’re struggling with your passwords, it might be the sign of a bot attack. You can use analytic tools like Google Analytics and your access logs to track those failed login attempts over time.

  • Identify Malicious Bots within Browsers:

Another way to identify malicious bots is to look at particular information contained in HTTP headers. Internet browsers generally have clear headers’ image. In normal browsing, the link within a browser will generate a “referrer” header that will be included in the next request for that URL.

However, traffic generated by a bot might not have a “referrer” header or it will look “fake”. The bots that look the same in every traffic flow are likely to be highly malicious.

  • Failing of Gift Card Numbers:

Botnets are also used to steal the value from genuine gift cards. It is easy to target gift card accounts with bots.

This is because companies don’t ask for a billing address, account name or personal info when attackers get their hand on gift cards account. That’s why attackers can use several combinations to get valid pairs of card numbers and pin codes. When an invalid pair is made, it generates a failed validation notification. If your gift card validation fails several times, consider it a solid signal that bots are attempting to steal your customer’s gift card balances to resell them on the dark web.

  • Increase in Irregular Page Viewing Patterns:

A human customer is likely to check the things that appeal to them. They look for their desired items and check out. What if they check every single product page on your website—or even half of those pages?

Scraper bots are used for this purpose as they are only aimed at the product pages. Those bots also visit the search page numerous times during a session. Unusual sessions generally include ridiculous searches and can be a sign of a bot attack. Besides, those sessions could be longer as it takes bot time to copy content in large volumes.

So these are the things to look for in your network to keep the risk of malicious bots at a bay. Plus, you can install effective anti-malware software to add extra layers to your cybersecurity.

DARK WEB EMAIL MONITORING


Dark web email monitoring is just gaining popularity in the cyber world. Talk about second chances, the dark web is one of such rare opportunities. When Hackers steal personal information like credit card numbers, bank account passwords, postal/IP addresses or even social security numbers. The process doesn’t end at stealing, hackers make transactions with the stolen data.

WHAT DOES DARK WEB EMAIL MONITORING DO?

Whenever there is a hack, the dark web creates awareness for its users. Dark Web Monitoring helps scan the web for any leaked personal data so the owner of such data can act promptly to protect their accounts.

Below are a few steps you can take as an additional line of defense against further threats:

  1. SCAN YOUR COMPUTER

There is a possibility that your passwords and keystrokes were monitored and exposed as a result of viruses on your computer. Therefore, scanning your computer for possible malware when your email is found on the dark web is a smart and safe thing to do.

  1. BOOST YOUR PASSWORD STRENGTH

Emails found on the dark web is often as a result of a successful phishing scam. To strengthen your password to make it more secure, ensure:

  • Your password is lengthy (up to 15 characters)
  • Use a mixture of uppercase and lowercase letters
  • Add numbers and symbols
  • Avoid using your name or common words
  1. CREATE AN EMAIL FOR JUNK MAIL

Most often than not, many recent sites require intending users to sign-up using their email addresses. Therefore, it is important to have a side email for unnecessary profiles. This is because when any of these insignificant sites are hacked, your primary email will not be found on the dark web. This means there will be less damage to your vital information due to less exposure.

  1. VERIFY YOUR ACCOUNTS

On receiving a breach alert through dark web email monitoring, check your bank accounts to ensure no money is missing and that no strange activity has occurred. Carry out these checks regularly because occasionally hackers don’t defraud your account(s) immediately after gaining illegitimate access. They tend to wait a while and allow you to lose guard.

  1. USE TWO-STEP AUTHENTICATION

Don’t limit access to your account through the conventional email and password. Rather, add another vital step to the process by having to verify your login attempt typically through a text message containing a randomly generated code. This helps add further security and reduces exposure to hackers.
