How do hackers hack? How do they gain access to a network? ANVEE ALDERTON, channel manager at Trend Micro Southern Africa, helps us understand cyber-attacks.
Our idea of hackers is that of sinister individuals, all working alone, hunkered over computers in a darkened room. This is actually a far cry from the truth. Hackers, these days, are sophisticated, organised and look a lot like you and me.
Investigation and security company Nuix recently published The Black Report, in which it surveyed hackers and penetration testers. The survey showed that cyber criminals can access a network within six to 24 hours in order to extract data. The report also revealed that 75% of companies that have been penetrated don’t do more than peripheral reinforcement of security.
What does this tell us? Attacks are getting far more complex in nature, with many hackers working in groups, or syndicates. Spread out through the globe, and with access to a relative amount of funds, these groups are able to perform in-depth attacks. More than that, they are regularly developing new malicious software.
I am often asked why hackers launch attacks. There are three primary reasons:
- For the challenge. Some hackers like to test their skills or choose difficult targets to improve their skills.
- For financial gain. Information can be bought and sold as with anything else. Scammers, rival companies and even nation states pay highly for sensitive data.
- To disrupt and cause chaos for businesses – usually as a statement or as a form of activism.
There are several ways that a hacker can access your network. The first, is using a method called “social engineering”. This means that the hacker interacts with someone in the target business and cons them out of the information that they need.
Hackers also use more sophisticated means of gaining access by exploiting vulnerabilities, using backdoor controls and going as far as stealing and using valid credentials. They may also employ stealth, using methods undetectable to standard security systems. This is the kind of thing that is regularly portrayed in film and TV.
Once the hacker has what he needs, he is able to target network and leave behind malware, leaving him free to move around the network as he pleases. The information, or data, that has been deemed valuable, is then extracted.
This would logically mean that this specific cyber-attack is completed, that the hacker has moved on, and there is no longer a threat. This, however, is not the case. Most companies don’t detect the hacker’s presence for days or even months. This means that they can continue to remove valuable new data on a regular basis.
The institutions that they target are financial institutions, healthcare organisations, major retailers and more. This means that your personal information is exposed and fair game to the hackers involved.
The threats that a company can face can include ransomware, where malware is used to block the company’s access to their own data. The hacker then demands a sum of money in order to release the data – effectively, they hold your information to ransom. There is no guarantee, however, that once the ransom is paid that the data would be released.
Phishing and whaling is also a popular means of sending malicious links. Convincing subject lines, coupled with legitimate seeming addresses, means that people click through and inadvertently are exposed to malware.
Most common of all are scams. We all know to avoid sending R 1 000.00 to a fictitious foreign businessman, however, scams are not always that easy to spot. Information can be gained by scammers posing as a person from a bank or a service provider, and in that way, obtain personal information which they can use to access accounts.
A holistic approach to security is preferred, with a multi-level approach that relies on endpoint security, employee education and detection systems in addition to the traditional use of firewalls and antivirus.
Hackers not only cost a business money, but credibility as well. It is vital to have the right kind of security and education on all levels.
What does that mean? Prevention is the first place to start with an integrated approach. Vulnerabilities and potential threats need to be assessed and endpoints, servers and applications need to be proactively secured. Prevention also involves a human component: staff need to be educated about not opening suspicious links or clicking through to suspect sites.
It’s also important to be able to detect the more advanced forms of malware that managed to slip through the first stage. Risk assessment and analysis provides insight into the impact of threats.
Finally, if there is a threat present, it is important to respond immediately with creating a real-time signature which is shared with all endpoints and gateway security. This is how you avoid future attacks.
It’s not enough to just do one thing, for example, protection. An integrated approach to cyber security is more effective and can not only save a company money, but their reputation as well.

How we use phones to avoid human contact
A recent study by Kaspersky Lab has found that 75% of people pick up their connected device to avoid conversing with another human being.
Connected devices are becoming essential to keeping people in contact with each other, but for many they are also a much-needed comfort blanket in a variety of social situations when they do not want to interact with others. A recent survey from Kaspersky Lab has confirmed this trend in behaviour after three-quarters of people (75%) admitted they use a device to pretend to be busy when they don’t want to talk to someone else, showing the importance of keeping connected devices protected under all circumstances.
Imagine you’ve arrived at a bar and you’re waiting for your date. The bar is busy, and people are chatting all around you. What do you do now? Strike up a conversation with someone you don’t know? Grab your phone from your pocket or handbag until your date arrives to keep yourself busy? Why talk to humans or even make eye-contact with someone else when you can stare at your connected device instead?
The truth is, our use of devices is making it much easier to avoid small talk or even be polite to those around us, and new Kaspersky Lab research has found that 72% of people use one when they do not know what to do in a social situation. They are also the ‘go-to’ distraction for people even when they aren’t trying to look busy or avoid someone’s eye. 46% of people admit to using a device just to kill time every day and 44% use it as a daily distraction.
In addition to just being a distraction, devices are also a lifeline to those who would rather not talk directly to another person in day-to-day situations, to complete essential tasks. In fact, nearly a third (31%) of people would prefer to carry out tasks such as ordering a taxi or finding directions to where they need to go via a website and an app, because they find it an easier experience than speaking with another person.
Whether they are helping us avoid direct contact or filling a void in our daily lives, our constant reliance on devices has become a cause for panic when they become unusable. A third (34%) of people worry that they will not be able to entertain themselves if they cannot access a connected device. 12% are even concerned that they won’t be able to pretend to be busy if their device is out of action.
Dmitry Aleshin, VP for Product Marketing, Kaspersky Lab said, “The reliance on connected devices is impacting us in more ways than we could have ever expected. There is no doubt that being connected gives us the freedom to make modern life easier, but devices are also vital to help people get through different and difficult social situations. No matter what your ‘connection crutch’ is, it is essential to make sure your device is online and available when you need it most.”
