Hacking and targeted cyber-attacks as a result of anti-competitive practices in business 0 373

Targeted Attacks

In ongoing consultations with clients, large companies named targeted attacks and hacking as two of their biggest security challenges since they can seriously impact the continuity of business activities in an organization.

Attackers have many means to infiltrate companies. However, many attacks, don’t require a very high level of technological sophistication. Instead, techniques like targeted social engineering, i.e. spear phishing, or the use of known vulnerabilities for which, patches may have been issued but businesses have not yet deployed, can lead to damaged reputation, revenue and data breaches.

On the other hand, high levels of sophistication can also be utilized as is in the case of a Zero Day attack.  Chief among these was Stuxnet, a recorded attack where malicious code successfully deployed four zero-day vulnerabilities to impede a uranium enrichment program in Iran, and which, according to media, was a state-sponsored attack.

There are many reasons why organizations become repeat targets. Their bank accounts contain more resources than those of an average person or small business and they also have considerable amounts of interesting data that can be monetized. Attacks targeting companies can also be used as a form of competition. Most often, this concerns data hunting, i.e. obtaining interesting information or intellectual property. These attacks can be accompanied by blackmail. For example, a client database is stolen from a company and is later approached by the perpetrators and asked, “what they are going to do about their loss”.

Different ways to monetize attacks bring different consequences

Organizations often find it difficult to admit they have been breached by these types of attacks. Consequently, this may give other companies the false impression that such attacks happen only occasionally. A typical example of targeted attacks, common in recent years, are DDoS as a Service – attacks, which are sponsored by one company to attack the website of another, with the effect of disrupting business and directing customers away from the targeted company and (possibly) towards the attacker’s “employer”. These are criminal tactics, and the attackers know very well which business areas to target for maximum gain.

There are of course other approaches. Take the example of the British National Health Service, which has become a frequent target of ransomware attacks. Digitization of health services has resulted in a situation where the malicious encryption of medical data may lead to a halt in medical interventions and surgeries. Under such conditions, targeted organizations are often more inclined to pay a ransom for the “hijacked” patient data.

In Kenya attackers have been known to target their attacks to banks and financial institutions, with figures of Ksh400 million being reported stolen from an unnamed local bank and Ksh29 million from National Bank of Kenya in 2018 alone.

Innovative approaches to old tricks

In many rural areas worldwide, one quick glance at powerlines will reveal how easy it is to make illegal connections to the power grid. As of late, cyberattackers have followed a similar model, focusing their resources on illegally mining various cryptocurrencies, which have proven to be highly popular in the public’s imagination.

A more complex example was a targeted attack meant to infect StatCounter, which provides a service  very similar to Google Analytics and uses a special script legitimately placed on websites to obtain data about website visitors. In this case, attackers successfully breached StatCounter and subsequently gained access to the service’s end users by injecting JavaScript code in all websites that use Stat Counter’s service.

The problem came to light when visitors navigated to the now compromised websites which contained the infected scrip, and who’s devices then began covertly mining bitcoins for the attackers. During the second stage, the attackers proceeded to steal bitcoins directly from infected devices when they attempted to access a popular cryptocurrency exchange. To get an idea of the scale of such an operation, StatCounter can be found on more than two million websites.

Such an attack means that system resources of infected devices at the company legitimately using the service are additionally tasked to mine. This may not concern only computers, but also mobile devices and especially servers. The subsequent cryptomining accelerates wear and tear on devices and also increases electricity bills. In addition, we should not forget that malicious cryptomining code is usually capable of uploading other types of malicious script onto the network.

Investigations may take months and are looking for a needle in a haystack

When a large company falls victim to such an attack, it is necessary to carry out a complicated investigation of what happened and how the company has been affected. Research shows that it takes about 150-200 days for companies to find out they’ve been infected. Further investigation regarding the method by which the company was infected and where the malicious code originated may take even longer.

Facing such substantial risks, large companies should leverage solutions like ESET Dynamic Threat Defense to detect new, never before seen threats.

How To Easily Set Up a VPN at Home 0 207

Woman working at home

As the COVID-19 pandemic has many organizations switching employees to remote work, a virtual private network is essential for countering the increased security risks

Probably, you have been forced to work from home due to the COVID-19 outbreak (recommended to reduce the spread of the virus). However, you are wondering how you will set up your VPN to enable secure communication.

Well, don’t agonize too much; we shall first explain to you what a VPN entails. And then, provide you with a step by step procedure for setting a basic Virtual Private Network. Here we go!

First, what is a Virtual Private Network (VPN)?

Essentially, a VPN is a private channel within a wider (open) network that enables you to communicate with your peers (other nodes with similar settings) without leaking your information through the use of encryption.

Besides, you can utilize a VPN to initiate communication through any network without revealing your location. In any case, a significant number of vendors deal with clients needing such services to avoid being tracked or be able to bypass particular network filters. 

However, in our case, we shall consider a home office VPN that will create a communication tunnel for your practical and secure home office communication.

Is it necessary to set up a virtual private network?

For there to be any communication between two endpoints ─ your pc and the computer in the main office –, they must be configured.

In this case, you’ll require the services of your IT department (if you have one), who will guide you regarding the applications to install, as well as provide you with VPN credentials depending on your needs. Upon installing and configuring the said app, you can automatically establish communication through the provided link. Easy-peasy, right?

On the other hand, if you don’t have an IT department behind your back, then you may have to do it yourself. These shouldn’t; however, scare you at all; it’s not as tough as you might imagine.

But before we explore the nitty-gritty of setting up the VPN, we first need to identify the options we have. In our case, we shall examine two options:

  • Open VPN: standard in small office/home office and business-class routers
  • IP Sec: Is Built-in and commonly used by desktops, smartphones, and laptops

The Open Virtual Private Network

This type of VPN has been around for a long time and has proved itself secure and reliable. It is ideal for small office/ house offices, as well as business-class routers, thanks to its open-source nature.

Procedure for installation

  1. On a contemporary device, go to the router’s configuration screen and click the relevant buttons to access your office network
  2. Download the configuration file generated by the router
  3. Use this file to configure/setup the OpenVPN in your pc, smartphone, or desktop that you want to use to access the Network behind that particular router. In case you get stuck somewhere, you can download or follow an online tutorial for your specific router.
  4. Download the required apps that will enable you to access your new home office VPN from this website.
  5. Install the downloaded applications and then configure them using the files generated when setting up the Open VPN on your office router.

In the event you find the going tough, you can always consult with an online tutorial or IT personnel.

Internet Protocol Security

IPsec is also another technology that has been in use for an extended period to provide reasonable security. It utilizes the same working principles as the OpenVPN; however, it is mostly used on lower-cost routers. Besides, it is a built-in technology in most desktops, laptops, and smartphones; therefore, it eliminates the need for installing another application on your device.

The installation process is similar to that one of OpenVPN. However, implementing a particular router IPsec can sometimes be a little more complicated compared to installing an open VPN.

Fortunately, with the use of native tools on your remote endpoints, you can offset this by just typing in a few things, such as the required IP address and credentials.

Final thoughts

Conclusively, these are some of the simplest virtual net protection options you can install on your home system without requiring massive/no input from IT experts.

Importantly, you will need a beefier than standard broadband for quick communication over the VPN. Also, you may experience slower connections due to the much horsepower required to keep the connection encrypted and tunneled. Nevertheless, this is a small price to pay in exchange for a secure home office communication.

In case you required any advice regarding VPN options or installation services, then ESET has been here for you for over 30 years. We want to assure you that we will be here to protect your online activities during these uncertain times, too.

How To Improve Communication Security with MFA 0 603

Person working on two factor authentication

Remote work can be much safer with the basic cyber-hygiene practices in place – multi-factor authentication is one of them

If you are working from home due to the coronavirus pandemic, it is essential to integrate two-factor authentication (2FA) or multi-factor authentication in your daily login routine. That way, you can beat fraudsters at their own game, since the security of your essentials isn’t wholly dependent on passwords alone.

The interesting bit with this technology is that you may have already seen it in action; for instance, when requesting access to your bank account via your smartphone. In this case, you must enter the one-time code sent to you in addition to your password to gain access.

See, enabling such double authentication processes on all your logins can make it difficult for scammers to access your accounts even if they compromise your passwords.

That said, you may now want to know which MFA option to use? Well, we take a look at some of the ways you can utilize MFA to bolster the security of your connections when working remotely.

  1. First, the use of a physical token

To implement this technique, you will require a physical device such as a security USB key, a key fob, or a similar item that will generate a secure code for verification purposes.

You’ll mostly be required to integrate this method if you need access to your cloud-based applications, online office applications, or corporate office technology. The YubiKey or Thetis is an example of such a device that you can purchase with less than US$50.

For convenience purposes, most of these devices are designed tiny; you can carry them in your pant pocket or hang them on a keychain for safety purposes. 

2. Use of a mobile phone

Most likely, you own a smartphone, right?

If yes, you can use it to boost your MFA security capabilities. For instance, you can download an authentication app such as Google Authenticator, ESET Secure Authentication, or Authy for your use.

The only caveat here is to ensure your source has a reputable security background. This is informed by the fact that the app is going to reside inside your smartphone, which is also vulnerable to security threats; therefore, robust security is required to avoid pre-emptying your security efforts.

Importantly, be on the lookout for spam messages when using your phone as they can trick you into compromising your accounts.

Fortunately, if you download applications from reputable sources, you can be offered a solution in case you have an issue with the platform itself.

3. Use of Biometrics

Factually, no single human being shares a fingerprint or retinal scan with another. This unique feature has been conveniently utilized overtime to provide robust multi-factor Authentication. 

You can also utilize the same to secure your connections.  For instance, you can take a picture of your face or scan your fingerprint using a biometric reader – currently, a common feature in smartphones or other devices ─, and then integrate it in your login procedure. These will prevent any other user from accessing your accounts or private information.

On the flip side, some folks feel that the technique is somehow creepy; therefore, give it a wide bath. Besides, it can present a challenge when you need to reset your bio features if your service provider is hacked.

Final thoughts

When scouting for a suitable MFA option for your needs, it is vital to consider one that can easily fit your routine. This stems from the fact that without proper utilization, an MFA option can’t protect you.

Similarly, an MFA technique can allow some side benefits as well. For instance, in the event of a security breach, you will be notified that your password has been interfered with; this can enable you to implement mitigation measures. Not only that, but you also get protected from the would-be attack since the fraudsters wouldn’t have access to your other factors.

In case you require a secure authentication application or consultation regarding MFA options, then ESET has been here for you for over 30 years. We want to assure you that we will be here to protect your online activities during these uncertain times, too.
