Hacking and targeted cyber-attacks as a result of anti-competitive practices in business 0 93

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.

Play it safe during FIFA 2018 0 960

We do realize that you’ve been caught up in the hurly-burly of the FIFA World Cup, but surely you have a few minutes to spare and peruse our roster of tips to stay safe online not only during the soccer spectacle. While you’re at it, recognize that no single player, no matter how stellar, is enough to put you on a path to success. In fact, being even one player short can be enough to trip you up. What should the pillars of your cybersecurity game plan be, then?

#1 A stitch in time saves nine

Last year went down in history for two serious cyber-incidents – the WannaCryptoroutbreak and the Equifax hack – that served up powerful reminders of the merits of swiftly squashing security bugs. 2017 also saw the highest number of  vulnerabilities reported.

So the number one player in you security team is updates. In your home settings, making sure that automatic updates are enabled for your operating system and software is an easy step to take to keep attackers away.

 

#2 Prune your team

Get rid of that disgruntled bench-warmer who ends up sapping your team’s morale. Software that you hardly ever use can become a liability simply by increasing your attack surface. To further reduce the possible entry points for cybercriminals, you may also want to disable unused services and ports, and ditch programs that have a track record of vulnerabilities.

For your browser, consider blocking ads and removing all but the most necessary of browser add-ons and plugins. While you’re at it, shut down the accounts that you no longer need and use your high-privilege, or admin, account only for administrative tasks.

#3 Practice strong password hygiene

One of the easiest ways to protect your online identities consists in using a long, strong and unique password or better still, passphrase, for each of your online accounts. It may well come in handy if your login credentials leak, for example due to a breach at your service provider – which, in fact, is far too common a scenario. Further, just as you’d never share your teams tactics with your opponents, you should never share your password with anybody.

If you’re like most people and find the need to remember many username/password combinations overwhelming, consider using a password manager, which is intended to store your passwords in a “vault”.

#4 Look before you leap

Even if you have the most complex of passwords or passphrases, be aware of where you input them.

Online, everything is just a click away, and scammers are keenly aware of that. In their pursuit of your personal information, they use social engineering methods to sucker you into clicking a link or opening a malware-laden attachment.

5 questions to ask yourself before clicking on a link are:

  1. Do you trust the sender of the link?
  2. Do you trust the platform?
  3. Do you trust the destination?
  4. Does the link coincide with a major world event like the FIFA worldcup? (Cyber criminals tend to be opportunistic this way)
  5. Is it a shortened link?

#5 Add a factor

When aiming for secure accounts, you need to up your ante by using two-factor authentication, particularly for accounts that contain Personally Identifiable Information (PII) or other important data. The extra factor will require you to take an extra step to prove your identity when you attempt to log in or conduct a transaction. That way, even if your credentials leak or your password proves inadequate, there is another barrier between your account and the attacker.

#6 Use secure connections

When you connect to the internet, an attacker can sometimes place himself between your device and the connection point. To reduce the risk that such a man-in-the-middle attack will intercept your sensitive data while they are in motion, use only web connections secured by HTTPS (particularly for your most valued accounts) and use trusted networks such as your home connection or mobile data when performing the most sensitive of online operations, such as mobile banking. Needless to say, secure Wi-Fi connections should be underpinned by at least WPA2 encryption (or, ideally, WPA3as soon as it becomes available) – even at home – together with a strong and non-default administrator password and up-to-date firmware on your router.

Be very wary of public Wi-Fi hotspots. If you need to use such a connection, avoid sending personal data or use a reputable virtual private network (VPN) service, which keeps your data private via the use of an encrypted “tunnel”. Once you’re done, log out of your account and turn off Wi-Fi.

#7 Hide behind a firewall

A firewall is one of your key defensive players. Indeed, it is often thought of as the very first line of defense. It can typically be a piece of software in your computer, perhaps as part of anti-malware software, or it can be built into your router – or you can actually use both a network- and a host-based firewall. Regardless of its implementation, a firewall acts as a brawny bouncer that, based on predetermined rules, allows or denies traffic from the internet into an internal network or computer system.

#8 Back up

A backup is the kind of player who doesn’t get much time on the pitch, but when he does get the nod, he can “steal the show”. True, we might have spoken ill of bench warmers earlier, but a reliable backup is definitely not the kind of player to spoil your team’s chemistry.

Your system cannot usually be too – or completely – safe from harm. Beyond a cyber-incident, your data could be compromised by something as unpredictable as a storage medium failure. A backup is an example of a measure that is corrective in nature, but that is fully dependent on how hard you “practiced”. Or, as Benjamin Franklin put it, “by failing to prepare, you are preparing to fail”. It will cost you some time and possibly money to create (time and time again) your backups, but when it comes to averting (data) loss, this player may very well save the day for you.

#9 Select security software

Even if you use your common sense and take all kinds of “behavior-centered” precautions, you need another essential addition to your roster. At a time when you’re pitted against attackers who are ever more skilled, organized and persistent, dedicated security software is one of the easiest and most effective ways to protect your digital assets.

A reliable anti-malware solution uses many and various detection techniques and deploys multiple layers of defense that kick in at different stages of the attack process. That way, you’re provided with multiple opportunities to stymie a threat, including the latest threats, as attackers constantly come up with new malicious tools. This underscores the importance of always downloading the latest updates to your anti-malware software, which ideally are released several times a day. Top-quality security software automates this process, so you needn’t worry about installing the updates.

#10 Mobiles are computers, too!

Much of this article’s guidance also applies to smartphones and tablets. Due to their mobility, however, these devices are more prone to being misplaced or stolen. It is also of little help that users tend to view security software as belonging in the realm of laptops and desktops. But mobile devices have evolved to become powerful handheld computers and attackers have been shifting their focus to them.

There’s a number of measures you can take to reduce risks associated with mobile devices. They include relying on a secure authentication method to unlock your device’s screen, backing up the device, downloading system and app updates as soon as they’re available (preferably automatically, if possible), installing only reputable apps and only from legitimate stores, and making sure to use device encryption if it’s not turned on by default.

A dedicated mobile security solution will also go a long way towards enhancing your protection from mobile threats. This includes a scenario whereby your device goes missing, so you are then able to use the suite’s anti-theft and remote-wipe functionalities.

#11 Be aware

The final team member is, in fact, you – the keeper. Stay vigilant and cyber-aware and educate yourself on safe online habits. Don’t ever say, “it won’t/can’t happen to me”, because everyone is a potential target and victim. Recognize that one click is enough to inflict major damage on yourself and others, and that breaking good security practices for the sake of convenience may come back to bite you worse than Luis Suárez did in 2014. After all, how secure we are is largely dependent on how we use the technology.

So there you have it. You may want to enjoy the soccer now.
