​What is a Botnet?

Have you heard the word Botnet? Sounds scary, doesn’t it? It is a network of infected devices that cybercriminals use for their malicious purposes. In the world, there are millions of infected devices, maybe even billions, and they are just a few clicks away from attacking their next target!

​What is Botnet?

A Botnet is a network of infected devices (a.k.a. hijacked devices or zombie computers) that cybercriminals first infect and later use for various cyberattacks, including DDoS attacks, SPAM spreading, phishing attacks, and more. The term Botnet is a combination of two words. The first is “bot” short of “robot”, which means an automated machine, that can perform a specific task. The second word is “net”, and it comes from “network” because here we are talking about multiple devices that can be triggered at once.

One feature of the Botnet that makes it so dangerous is that the users of the infected devices usually have no idea that the devices have a malicious code on them. They might not see a spike in resources’ use, or they can think that the devices are experiencing a bug making them work more. Botnets are sneaky threats!

​What are Botnets used for?

  • DDoS attacks. An attacker can use its Botnet or Botnets and create a massive wave of traffic towards a particular target. The goal is to overwhelm the target (usually a server) with so many DNS queries that it won’t be able to answer any, including those coming from regular users, and cause downtime. The scenario could be many times worse if the cybercriminal uses DDoS amplification and create even heavier traffic.
  • Mining cryptocurrency. Your device might be mining cryptocurrency for somebody else, and you might not even know it. It will use your computer’s or mobile phone’s resources, to mine. That way, the attacker has many zombie devices that can bring a lot of profit without investing in hardware or paying any electricity or internet bills.
  • Phishing attacks. Phishing attacks are a tricky way to get someone’s username, password, or other valuable information. A botnet device could write messages on your behalf, asking for information from your contacts, that later the criminals could use to attack their accounts. A phishing attack could also lead your contacts to a fake site that looks a lot like a real one, and there they might input their personal data or bank data.
  • Spam spreaders. A hijacked device can be a spreader of spam messages. If your device runs a hacker’s script, you might be spreading dangerous messages all around the Internet. Those messages could be directed to your contacts on your behalf or anonymously. Either way, your device could be the “recruiter” of new devices for the Botnet, helping phishing attacks happen or spreading information around the Internet.

​How to protect ourselves from Botnet attacks?

  • Use strong passwords and 2FA. Make your passwords as complicated and large as possible. Adding a second factor in your authentication will increase your security a lot.
  • Keep your devices up to date. The latest software (OS included) will have the latest security patches that can protect you better.
  • Don’t click any link or open any attachment that looks strange, even if it comes from a trustworthy contact of yours. It might start malicious software that will infect your devices.
  • Use antivirus software for your devices. It can detect the infected file on time and save you from the infection.
  • Look for abnormal activities on your device. A sudden spike in CPU or GPU use might indicate that the computer is working for somebody else.

What is Deceptive Technology?

Cyberattacks are getting worse each day. DDoS attacks, ransomware, phishing attacks, data breaches are just a few of the biggest dangers a company can face. But can you do something to protect your business against all these ever-evolving cyber attacks? Yes, you can be smart and use the latest method of defending yourself – Deceptive technology! 

​Why deception?

Deception tactics have been in use for thousands of years. Militaries have used deception to trick their opponents on the battlefield to get leverage, direct a battle, move troops to the right place, and many more sneaky tricks. 

The deception works by fooling the attack into doing exactly what the defendant wants it to do. That way, they can negate the negative effect and even counterattack. 

​What is Deceptive Technology? 

Deceptive Technology is a strategic approach to cyber defense. The idea is to identify an attacker, trick the attacker, and diver its efforts to another place, a decoy or a trap. The decoy can be a server, acting similar to the primary server, but specially prepared for these cases, so if it takes an attack, it does not affect the organization in a bad way. 

The big advantage is that Deceptive technology can analyze the behavior of the hackers, even if they are trying to use zero-day attacks, and offer alert and protective behavior automatically, without humans intervening. 

Deceptive Technology is usually additional protection, not the only security measure an organization takes. It is like the last defense, again worse attacks. 

​How does the deception work?

The company using Deceptive Technology sets decoys, hides its main servers, and sets misleading information that attacks could find to redirect the attack. 

It does not work based on logs, and reports like a typical information and event management solution would do. 

When the attack happens and the criminals byte the bait, the security team will receive an alert with information about the current threat. The team can see the tactics the criminals are using, exactly what vulnerability they are exploiting, and have time to prepare a way to shut down the attack. 

​Why is Deception Technology Important?

There are a few main points, why Deceptive Technology is so important:

  • Improved threat detection. The Deception Technology can serve as a periscope that can accurately see the threats and still have broad coverage. It can detect the various types of incoming troubles, not just signature-based ones, that you already have a defense. 
  • Risk awareness. Having this extra security measure, you will see what kind of risks are there for your company. You can test different scenarios like setting up a fake “new product” page and see if somebody tries to hack it and how. 
  • Low false positive. There are a lot fewer alarms set up by false signals. That way, you can save a lot of effort for your security team and not waste their time with false-positive alerts


Deceptive Technology is not for every business. It is mostly focused on the 1% that needs the best possible protection that is out there. It is an additional level of security that not all enterprises can effort, but it can be very effective and save a lot of trouble for the victims. 

What does DNSSEC mean?

DNSSEC meaning

Domain Name Security Extensions (DNSSEC) is a great way to add an extra security layer to your domains. It is an advanced DNS feature, which attaches digital signature (DS) records to the DNS information. So, that way, it can establish the authenticity of the source domain name.

The purpose of which it is designed is to protect Internet users from falsified DNS data. An example of such a case can be a misleading or malicious address rather than the actual address you wanted to visit.

Once you enable DNSSEC, the DNS lookups will have to use a digital signature to prove that the origin of the site’s DNS is accurate. It is very helpful for preventing some types of attacks. In case the digital signature does not match, the browsers will not open the site.

What is the way DNSSEC works?

The main goal of DNSSEC is to protect Internet users from forged DNS data through validating digital signatures inserted in the data. 

Whenever a user wants to enter a domain name in a browser, the resolver verifies the digital signature.

The digital signatures in the data and those that are in the master DNS server have to match. Only then is the data allowed to access the user computer, which is making the request.

These digital signatures are making sure that the user is communicating with the website that he intended to visit.

DNSSEC implements a system of public keys and digital signatures to validate the information. To alongside existing DNS records, it adds new records. These new type records are DNSKEY and RRSIG, which can be retrieved such as the more common records, like A, CNAME, and MX.

They are implemented to digitally “sign” a domain with a method named public-key cryptography.

Nameserver, which is signed, has a private and public key for every zone. Every time a user makes a request, it sends data signed with its private key. Then the recipient unlocks it with the public key. If someone attempts to send misleading information, it won’t be able to unlock appropriately with the public key, so the recipient will identify that the data is false.

What does it protect against?

The fundamental protection that DNSSEC can provide is to limit third parties from falsifying records. It also guarantees the integrity of the domain by restricting:

False zones: DNSSEC can be beneficial for protecting versus malicious DNS attacks that make unfair use of the DNS system and give imitation results for zones. They may not even exist actually, and attackers benefit from gaps between zones. DNSSEC provides mechanisms to avoid gap usage and secures the whole zone. That is also called the authenticated denial of existence. 

DNS Cache Poisoning: This is a form of man-in-the-middle attack. Criminals flood a DNS resolver with fake DNS data. In some cases, these attacks can increase to a large number and set a false end result inside the cache of the DNS resolver. As a result, the DNS resolver gives this malicious and false web address to every user that is requesting that specific website. This continues until the TTL (Time-to-Live) expires.

5 most common phishing attacks

Phishing attacks can be hard to notice. Be careful when a suspicious sender wants you to open any URLs or download a file. Let’s explain a little bit more. 

What does a phishing attack mean? 

A phishing attack is a type of cyber attack. The attackers are operating in a way to make the victim take one of the next actions:

  • Enter data. A fake site, visually alike to a popular one, asks you to fill in your information, such as emails, passwords, usernames, and bank information. 
  • Download a file. The file contains a virus, which affects your device. They could make you pay a ransom to return control over your device.

They send a message that looks traditional and makes it hard to identify a difference from any other. Usually, it is professionally written and offers something that the victim wants. Another way is to make the message sound urgent, such as changing the password in X amount of time.

Cybercriminals are using this method for a long time. The term “phish” associates the word fish and the way we lure a fish with bait. 

Email phishing

The largest number of phishing attacks are sent via email. With a fake domain, which is similar to a true company, they send thousands of requests. The fake domain usually contains letters change, for example, placing “n” and “r” next to each other to make “rn” rather than “m.” Another way is to apply the company’s name as a part of the email address.

The main rule for spotting a phishing email is always checking the email address of a message that wants you to download a file or click a link.

Spear phishing

Spear phishing involves email too. The difference is that spear phishing emails are sent to a specific person. Attackers for this attack already have some or all information about the victim like:

  • Name 
  • Job title
  • Place of employment
  • Email address 
  • Detailed information about their job role. 


Whaling attacks are even more targeted, aiming at senior managers. 

The end goal of this attack is the same, but the technique is a lot more complex.

A common variety of whaling is scams involving false tax returns. Malicious URLs and fake links are not useful in this case.

Attackers highly appreciate tax forms containing useful information: names, addresses, and bank account information. 

Smishing and vishing

Telephones replace emails as the way of communication, with bot vishing and smishing. Smishing includes attackers sending text messages. The content is similar to email phishing. Vishing, on the other hand, includes a telephone conversation.

An example of a vishing scam is when the criminal presents himself as a bank fraud investigator. The attacker is telling the victim that their account has been breached and will ask to verify their identity or provide payment card information.

Angler phishing

Angler phishing is an approximately new attack. Social media allows attackers a lot of ways to trick people. For example, fake URLs cloned websites, tweets, and posts. Also, instant messaging allows basically the same as smishing. These vectors can be implemented and applied to convince people to download malware or reveal personal information.

Furthermore, cybercriminals can benefit from the already posted information in social media to make a highly targeted attack.

DDoS attack – Everything you need to know

What does a DDoS attack mean?

Distributed Denial of Service, which is for short, called DDoS, is a cyber-attack. It’s performed to disrupt essential targets like a network, system, or server. That is achieved by overwhelming them with lots of traffic, which is coming from many devices. The word “distributed” refers to the many various sources that are used to achieve the attack. When the target is down, the DDoS attack is complete. The outcome is simply not allowing any user to access it.

The DDoS attack can be of several kinds. Techniques can modify, or they could be mixed and accomplish a stronger hit to the target. Overall, any DDoS attack operates by infecting devices. If there are more connected to the Internet, more of them are going to attack the victim. This happens even globally and from any kinds of compromised sources like computers, servers, IoT devices, wearables. The target is not able to handle the traffic. It becomes sluggish and eventually becomes completely drowned.

How does it work?

Internet-connected devices are the ones, which carry out DDoS attacks.

These networks include computers and other devices like IoT devices that are infected with malware. This way, for the attacker, it is possible to take control of them and operate remotely. Every one of these devices is referred to as zombies or bots. In addition, a group of them is called a botnet.

When a botnet is built, the attacker can proceed to perform the attack. Each bot receives instructions remotely.

The victim’s network or server, which is affected by the botnet, sends with each bot request to the IP address of the target. Like that, the network or server likely gets flooded. The result is a denial of service to accessing regular traffic.

The reason for which separating regular traffic and attack traffic is so difficult is simple. Every bot is presented as a legitimate Internet device.

The motive for DDoS attacks

DDoS attacks are gaining more popularity and becoming the most common kind of cyber threat. The number of attacks performed is growing rapidly. 

The motives that are behind the attack are mainly:

  • Shakedown – The ones that apply DDoS attacks or using them as a threat and like a method for forcing their target to pay them. 
  • Business disputes – Companies strategically can use DDoS attacks to take down the site of an opponent.
  • Philosophy – These people are called “hacktivists”. Their targets are usually sites that implement an ideology, which the attackers disagree with.
  • Boredom – These are cyber vandals who are searching for an adrenaline rush. They typically use pre written scripts to start DDoS attacks. 

Keep yourself safe from DDoS attack. 

If you want, there is a method to defend yourself from DDoS attacks. In case your name servers are the main target of the DDoS attack, there is a way to protect them. What you are going to need is a DDoS protected DNS. The essential of it is that it is a network, which contains a strategically located in various places servers. So they are able to balance the load intelligently. So providers of DDoS protected DNS can mitigate the traffic successfully. 

Also, if one server completely goes down, your domain will continue to resolve, thanks to the other servers.
