How Do Hackers Easily Crack Your Strongest Passwords — Explained

►
Apart from knowing the best methods to create a strong password, one should also be aware of the techniques used by hackers to crack them. The recent torrent of massive data breaches has made the jobs of hackers even easier as they are able to access the dumped data easily. In an explainer video, YouTube channel Computerphile explains the process of password cracking and the mistakes one commits while creating a new password.

Password storage and its encryption is a common question that’s often discussed in the cyber security world. At many occasions, when people mention encrypted passwords, they really mean hashed passwords. Unlike encryption, a password that’s undergone the hashing process, can’t be reversed using the same key.

However, thanks to the leaked password hashes on the file-sharing websites and dark web, our passwords are less secure than ever. Some of the latest data breaches affected millions of LinkedIn and TalkTalk users.

For a hacker, getting access to these password hashes, extracting real passwords and using them to compromise the online accounts isn’t a tough task. Using the same technique, the hackers are now increasingly targeting the social media accounts of technology CEOs–Mark Zuckerberg, Jack Dorsey, Marissa Mayer–and Hollywood celebrities.

Well, even if you are using a super safe password that has been created using some advanced techniques, these massive breaches have made them unsafe.

This process has been explained in an exceptional manner by the YouTube channel Computerphile.

https://www.youtube.com/watch?v=7U-RbOKanYs&feature=youtu.be

This cracking video shows a deep learning beast that uses 4 NVIDIA GPUs and a password cracking tool called Hashcat. Hashcat lets you do different types of password cracking. Thanks to these GPUs, Hashcat takes billions of plain-text passwords and hashes them using MD5 at a rate of 40 billion per second.


The presenter explains the process in detail and tells you the best practices that should be adopted while creating a new password. It’s always good to avoid small combinations and dictionary words in your password. I’ll also suggest you to keep changing your passwords from time-to-time.

Teardrop Attack : What Is It And How Does It Work?

►
Teardrop attack is a type of Denial of Service (DoS) attack which exploits the fragment offset field in the IP header to produce buggy fragments which are then delivered to the target machine. Unable to rearrange the fragments, the victim keeps on accumulating the fragments until it crashes.


As the name suggests, the Teardrop Attack works gradually by sending the fragmented packets to a target machine. It’s a type of a denial-of-service (DoS) attack which overwhelms the target machine with the incomplete data so that the victim crashes down.

In Teardrop Attack, fragmented packets that are sent in the to the target machine, are buggy in nature and the victim’s machine is unable to reassemble those packets due to the bug in the TCP/IP fragmentation.

In this way, the packets keep on getting accumulated over the victim’s machine and finally due to the buffer overflow, the target machine crashes down.
How Teardrop Attack works?
Here, I am taking a reference from the Juniper’s technical publication to illustrate how does it work —

As you can see in the above figure of IP header, which operates at the network layer, there is a field called fragment offset field.

Teardrop Attack and Fragment Offset:

Understand it like this — When a large amount of data is sent across the internet, the data is broken into the smaller fragments. Each of these fragments is assigned a number. When they reach the receiving end, these fragments are rearranged to reproduce the original data or message.
To identify the sequencing of the fragments, the fragment offset field holds the necessary information using which the target machine rearranges the sequence.
However, in the Teardrop Attack, the fragment offset field is made buggy by the hacker so the victim’s machine is unable to find the relative fragments.
So, as the name suggests, the buggy packets keep on accumulating at the victim’s side like teardrops and ultimately it leads to the machine crash.
However, modern networking devices can detect this discrepancy in a fragmented packet. Once they detect the problem, they simply drop the packet.

Top 10 Common Hacking Techniques You Should Know About

►
Using simple hacks, a hacker can know about your personal unauthorized information which you might not want to reveal. Knowing about these common hacking techniques like phishing, DDoS, clickjacking etc. could come handy for your personal safety.


Unethical hacking can be called an illegal activity to get unauthorized information by modifying a system’s features and exploiting its loopholes. In this world where most of the things happen online, hacking provides wider opportunities for the hackers to gain unauthorized access to the unclassified information like credit card details, email account details, and other personal information.

So, it is also important to know some of the hacking techniques that are commonly used to get your personal information in an unauthorized way.

1. Keylogger
Keylogger is a simple software that records the key sequence and strokes of your keyboard into a log file on your machine. These log files might even contain your personal email IDs and passwords.

Keylogger is one of the main reasons why online banking sites give you an option to use their virtual keyboards.

2. Denial of Service (DoS\DDoS)
A Denial of Service attack is a hacking technique to take down a site or server by flooding that site or server with a lot of traffic that the server is unable to process all the requests in the real time and finally crashes down.

For DDoS attacks, hackers often deploy botnets or zombie computers which have got the only work to flood your system with request packets.

3. Waterhole attacks
If you are a big fan of Discovery or National Geographic channels, you could relate easily with the waterhole attacks. To poison a place, in this case, the hacker hits the most accessible physical point of the victim.

For example, if the source of a river is poisoned, it will hit the entire stretch of animals during summer. In the same way, hackers target the most accessed physical location to attack the victim. That point could be a coffee shop, a cafeteria etc.

Once hackers are aware of your timings, they might create a fake Wi-Fi access point and modify your most visited website to redirect them to you to get your personal information.

4. Fake WAP
Even just for fun, a hacker can use software to fake a wireless access point. This WAP connects to the official public place WAP. Once you get connected the fake WAP, a hacker can access your data, just like in the above case.

5. Eavesdropping (Passive Attacks)
Unlike other attacks which are active in nature, using a passive attack, a hacker just monitors the computer systems and networks to gain some unwanted information.

The motive behind eavesdropping is not to harm the system but to get some information without being identified.

6. Phishing
Phishing is a hacking technique using which a hacker replicates the most-accessed sites and traps the victim by sending that spoofed link.

Once the victim tries to login or enter some data, the hacker gets that private information of the target victim using the trojan running on the fake site.

7. Virus, Trojan etc.
Virus or trojans are malicious software programs which get installed into the victim’s system and keeps sending the victims data to the hacker.

8. ClickJacking Attacks
ClickJacking is also known by a different name, UI Redress. In this attack, the hacker hides the actual UI where the victim is supposed to click.

In another word, the attacker hijacks the clicks of the victim that aren’t meant for the exact page, but for a page where the hacker wants you to be.

9. Cookie theft
The cookies of a browser keep our personal data such as browsing history, username, and passwords for different sites that we access. Once the hacker gets the access to your cookie, he can even authenticate himself as you on a browser.

10. Bait and switch
Using bait and switch hacking technique, the hacker runs a malicious program which the user believes to be authentic. This way, after installing the malicious program on your computer, the hacker gets unprivileged access to your computer.

How to avoid phishing attacks

►
1. Keep the network out of reach of criminals
According to the Verizon data breach investigation report published last month, phishing remains a major data breach weapon of choice. Trend Micro added that ransomware is expected to be one of the biggest threats in 2016 and that a single ransom demand will go much higher, reaching seven figures.
Remember, cyber criminals are lazy. If your organization is a tough nut to crack, they will move on to find more low hanging fruit.

2.Launch phishing simulations
Running phishing simulations followed by ad hoc, gamified training is a proven tool to increase awareness and reduce risk. Repeat the process at least once every two months - changing behavior is a process. Training is important, but continuous assessment is even better to set the right mindset.

3.Use Gamification as training methodology
Let’s admit it, people hate training. They are sick and tired of videos and training wizards with boring slides and bullets. Meanwhile, for us, the security managers, it’s not really measurable. This is why interactive training or ‘gamification’ is much more engaging. Plus, people love to get high scores to collect awards, so why not? Create fun and interactive games to deliver your messages.

4.Definitely include your senior management
They are main targets, especially for spear and whale phishing. Make no exceptions. Publicly promote their participation. It’s a good example for the rest of the company.

5.Use real-life examples
It’s best to hit your employees with emails they might actually receive. Change difficulty levels and start from the ground up. Don’t expect people to understand advanced phishing examples from day one. Teach them step by step on both phishing scenarios and training modules.

6.Enforce training, and follow employee progress
To make it effective, employees must understand this is serious. They need to be reminded if they ditched the training. It’s your job to make sure they like it. It’s all about the messaging. They need to understand that they have a critical role in protecting the company and its assets.

7.Encourage ongoing phishing reports
Make sure each and every employee knows how to report back to the security team about suspicious emails. Many people tend to believe that the technology on premise will automatically stop all malicious emails and attachments for them. Make sure they understand that they are an active line of defense.

8.Ever vigilant
Phishing is the No.1 vehicle used by cyber criminals to deliver malicious software to your organization. The level of sophistication is increasing dramatically so traditional defenses are lagging behind. Make sure people are aware of the risk and well trained to spot and report it as it happens.
