Free Internet Access? Don’t fall for this one

• Ads are created on Google, Facebook, popular search engines and social media platforms advertising free internet hours.
• The ads look professional and show up on general searches and on social media when surfing. This offers a sense of validity.
• Once you click on the ad, you will be taken to their website, where you will be asked to perform an action, such as
1. Filling out a form with your Personally Identifiable Information (PII)
2. Sharing your credit card information, and though you will be promised that your card won’t be charged, you may end up signing up for something or subscribing to a service for which your card will be charged later.
3. Sharing a few email IDs or phone numbers–basically contacts with whom you will be asked to share the message in return for free internet service.

How to stay safe?
As always, remember no one offers something for free. Whether it is free internet access or tickets to a concert, if it is something of value, then you will be expected to provide some value in return. Steer clear of offers that seem too good to be true. If you receive a message from someone you know and trust, please let them know that their link may be a problem. No matter what, don’t open a link from anyone if you aren’t entirely sure the links are valid.

Online shopping? Watch out for these red flags

Who doesn’t like online shopping? Online shopping has opened up a whole new world to us. Get whatever you want, whenever you want, without wandering from store to store. It doesn’t matter if it is too hot to venture outside or if there’s a blizzard out there, you do your shopping from the comfort of your couch and the stuff at your doorstep. You get great deals, some are better than in-store specials. But, did you know cybercriminals love the concept of online shopping as much as you do. Cybercriminals are exploiting the growing popularity of online shopping to cheat unsuspecting buyers through techniques such as phishing, malware injection, etc. Here are a few tips that may work to keep you safe from being a target of cybercriminals as you shop online.

How to determine if the ad or shopping site is genuine?
As you browse the web, you will come across various ads targeted at your interests. Businesses engage in ‘Retargeting’ which means they use cookies to target you with very specific ads until you buy something. For example, look at a wallet and, you will see ads for wallets on various other sites you browse even if they are not shopping sites. Are those ads genuine? Before clicking on any ad you see online and making a purchase, be sure to verify if the ad is genuine. The same goes for shopping sites. Before you shop, you need to ensure the site is genuine, especially since you will be sharing your credit card details or Personally Identifiable Information (PII) such as your address. Here are a few things to check before you make that online purchase.

English: Keep an eye out for grammatical errors or spelling mistakes in the ad. Fake ads and sites may look a lot like the actual ones, but spelling mistakes or grammar errors may tell the true story. Scammers don’t have content writers to write great sales content!

Check the URL: When at a shopping site, always check the URL in the address bar to ensure it is genuine. For example, if you see www.1amazon.com or www.amazon-usa.com, you should know it is not the same as www.amazon.com. Checking the URL also lets you detect website cloning and phishing. Website cloning is one of the most popular methods used by scammers to fleece consumers. As the term suggests, the cybercriminal first creates a ‘clone’ site that looks exactly like the original one, barring a very minor change in the URL.

Don’t Get Phished!
Phishing is when you receive a message, usually through an email or a text message asking you to take an action, such as clicking on a link, filling out a form, logging into an account, etc., Such messages look as though they are genuine. But, the form fill, account login, or link will take you to a spurious site where your information will be captured for bad use. Checking the URL will help you detect phishing frauds as well.

Check before you download anything: Sometimes you may receive a link and asked to download a coupon or a gift card that entitles you to a sizable discount. It may be a fraud. In fact, it probably is.

Download only from legitimate marketplaces: With so many shopping options it is tempting to download every new app that you come across. But, only download from authorized marketplaces like Google Play Store for Android or the App Store for iOs.

At the end of the day, remember, there is no free lunch. If something seems too good to be true, it probably is.

DNS Cache poisoning: What every SMB must know

1. As discussed before, one of the most common poisoning attacks is the DNS attacks. Cybercriminals try to corrupt your DNS server using theirs. You can prevent this by bringing a trained professional onboard for your DNS server set-up. An expert will know to set up your DNS server such that it has a minimum relationship with other, external DNS servers, thus limiting your attacker’s ability to corrupt your DNS server using theirs.
2. As a best practice, ensure that your DNS servers only store data related to your domain and not any other information. It is harder to corrupt the system when it focuses on a single element.
3. Another best practice is to ensure that you are up-to-date on all DNS security mechanisms and are using the most recent version of the DNS.
4. Ensure your site has, in layman terms, an SSL certificate and make sure it is HTTPS. Using encryption, a site with HTTPS protocol allows for a more secure connection between its server and the internet and is better at keeping cybercriminals out. Having an SSL certificate also ensures your site’s name shows up alongside the URL in the address bar. This is an easy way for visitors to identify if they are on a genuine site or not, thus helping them steer clear of phishing attacks and clone sites.

Data poisoning is one of the lesser-known and hence less talked about forms of cybercrime. But, it can inflict great damage–perhaps even more damage than the other obvious threats such as viruses and ransomware, because, unlike a Denial of Service (DoS) attack or a Ransomware attack where you know the moment the malware has hit your system, in a data poisoning attack, the malware is incorrect data that slithers into your system quietly like a snake and changes its overall functioning before delivering the big blow.

Protecting yourself against poison attacks

Data poisoning by way of logic corruption, data manipulation and data injection happen when the attacker finds a way to access your data set. The kind of poison attack varies depending on the level of access the attacker is able to achieve Here’s what you can do to ensure such access is prevented.

1. The data poisoning attacks discussed above adversely affect your IT system’s machine learning capabilities. So, the first logical step would be to invest in a good machine learning malware detection tool. These tools are different from the typical anti-malware tools you get in the market and are specifically designed to prevent machine learning capability poisoning.
2. Always follow general IT security best practices such as-
1. Training your employees to identify spam, phishing attempts, and possible malware attacks
2. Following good password hygiene, which means never sharing passwords and only using passwords that meet the required security standards
3. Having a powerful IT audit process, tracking and version control tools, so as to thwart any possible insider attacks
4. Ensuring the physical security of your IT systems by way of biometric access, CCTV systems, etc.,

Whether it is data poisoning or a malware attack, you certainly don’t have the time to look into all the security aspects yourself. Even if you happen to have an in-house IT team, this 24/7 monitoring may be too much for them to handle as you grow. Consider bringing a reputed MSP on board to help you with this, so you can focus on your business, worry-free, while they ensure your data is safe.

Poison Attacks: A quick overview

Smart technology is everywhere. Not just in our offices, but even in our day-to-day lives with tools like Google Home and Alexa becoming a commonplace. With technology becoming smarter every minute, the risks are increasing by the minute as well. Cybercriminals are finding new ways to corrupt our IT networks to disrupt our businesses, hold our data hostage and even clear our personal bank accounts. Some of the more overt, commonly known acts of cybercrime include hacking, phishing, and ransomware attacks. This blog discusses a lesser-known cybercrime–Poison attacks.

What are Poison attacks
Poison attacks are attacks on the ability of the system to make smart decisions. Think about this. How do systems make intelligent decisions? Based on the training or data they receive. This data is used to hone the artificial intelligence of the system to help make smart decisions. Poison attacks mess the very base–the training data set. Poison attacks basically skew the system’s data model in such a way that the output is no longer as intended. They create a new normal for everything. Poison attacks are primarily backdoor attacks. In a backdoor poison attack, the attacker creates a loophole in the core data rule and trains the system to adhere to that rule so it can be exploited at a later time. For example, let’s say, the access control for a particular file is set such that it will allow only those beyond the VP level to view the data. If someone changes the main parameter to include manager level in there, the core data set is violated and the system will not detect an intrusion by someone at the manager level, even if they log in with their credentials.

Unlike Ransomware, poison attacks don’t make much noise but cause far more damage as they can go undetected for a longer time. Follow our blog next week as we discuss the 3 common types of poison attacks

Watch out for these poison attacks!
Poison hamper the ability of the system to make smart decisions by disturbing the very core data set that is used to make a decision. Poison attack methodologies typically fall into one of the following 3 categories.

• Logic corruption
• Data manipulation
• Data injection

Logic corruption
In logic corruption, the attacker changes the basic logic used to make the system arrive at the output. It essentially changes the way the system learns, applies new rules and corrupts the system to do whatever the attacker wants.

Data manipulation
In data manipulation, as the name suggests, the attacker manipulates the data to extend data boundaries that result in backdoor entries that can be exploited later. Unlike logic corruption, the attacker doesn’t have access to the logic, so they work with the existing rule and push data boundaries further with a view to accommodate them later.

Data injection
In data injection, the attacker inserts fake data into the actual data set to skew the data model and ultimately weaken the outcome. The weakened outcome then serves as an easy entryway for the attacker into the victim’s system.

Employee training & Cybersecurity

Employee training will form a big part of the cybersecurity initiative that you will take on as an organization. You need to train your employees to identify and respond correctly to cyberthreats. Here are some employee training best practices that you can make a part of your cybersecurity training program.

Create an IT policy handbook
Make sure you have a handbook of your IT policy that you share with every new employee, regardless of their position in the company. This IT policy handbook must be provided to everyone–right from the CEO to the newest intern in your organization. Also, ensure this handbook is consistently updated. IT is evolving at great speed and your handbook must keep up

Make cybersecurity training a part of your official training initiatives
Cybersecurity training should be a part of your corporate training initiatives for all new employees. You can also conduct refresher sessions once in a while to ensure your existing employees are up-to-date on the latest cyberthreats. At the end of the training session, conduct tests, mock drills, certification exams. Good training includes assessment. Provide follow up training for those who need it. This strong emphasis on training will ensure your employees take cybersecurity seriously.

Day zero alerts
As discussed, the cybercrime landscape is constantly evolving. Every day, cybercriminals are finding new vulnerabilities to exploit, and new methods to steal your data or to hack into your system. Day zero alerts are a great way to keep your employees updated. Has a new security threat been discovered or an important plug-in released for the optimal functioning of a browser? Send an email to everyone spelling out clearly what the threat is and what they can do to mitigate it. Then, follow up to verify they took the necessary steps.

Transparency

Let your employees know who to contact in the event of any IT related challenges. This is important because someone troubleshooting on the internet for a solution to something as simple as a zipping up a file could end up downloading malware accidentally.

Considering the serious ramifications brought on by cybercrime attacks, it makes sense for organizations to strengthen their first line of defense against cybercriminals–their own employees.

Strengthening your cybersecurity policies

Formulating strong IT policies and laying down the best practices for your staff to follow is one of the best ways to prevent your business from becoming a victim of cybercrime. In this blog, we explore the various areas your IT policy should ideally cover.

Passwords: Your IT policy should cover

1. Rules regarding password setting
2. Password best practices
3. The implications of password sharing
4. Corrective actions that will be taken in the event the password policy is not followed

Personal devices

1. Rules regarding the usage of personal devices at work or for work purposes. Answer questions like
1. Are all employees allowed to use personal devices for work or do you want to limit it to those handling lesser sensitive data, or to those at higher in the corporate hierarchy as you assume they will need to be available 24/7? Regardless, you should spell out the regulations that they must follow. For example, requiring a weekly or monthly check for malware and updates to anti-malware software, etc., If only certain kinds of devices, software or operating systems may be approved as they are presumed to be more secure, then that should be addressed in the policy
2. Discuss best practices and educate your employees on the risks related to connecting to open internet connections (Free WiFi) such as the ones offered at malls or airports.

Cybersecurity measures

1. Document the cybersecurity measures that you have in place for your business. This should include your digital measures such as the software you have deployed to keep malware out–like anti-virus tools, firewalls, etc., and also the physical measures such as CCTV systems, biometric access controls, etc.,
2. Another example of a good practice is how you handle employee turnover. When someone quits your organization or has changed positions, how is the access issue addressed? Spell out the rules and regulations regarding the removal of a user from the network, changing passwords, limiting access, etc.,
