Ransomeware is quite possibly the most damaging online threat. Although there are numerous defences against it, DREW VAN VUUREN, data protection officer at ESET South Africa, believes the best is user education.
Ransomware is a very real threat to businesses and individuals alike, and when it comes to online security, it is arguably the most damaging threat. Yet, many people still don’t know what ransomware is, even though this type of cyber threat has been aggressively spreading over the internet, with results that can impact both a company’s finance and reputation.
And the threat is only going to get more hostile.
The simple fact is that there is limited protection against ransomware, with no antivirus or end-point security solution technology able to protect you. Protection comes down to user-education and good business practice, and for any business, it is a must have that disaster recovery is in place if they hope to come out of a ransomware breach relatively unscathed.
Ransomware is a malware that infects a computer and encrypts all its files. Cybercriminals then offer an ultimatum to their victim: pay the demanded ransom or lose your data forever. If you are susceptible and become a target you have no choice, either you pay or rebuild your system – there is no third option. However, if you take option number one and you pay the ransom, the chances are you will again be targeted and you end up perpetuating the cycle of infection and victimization.
There are two different types of ransomware – opportunistic and targeted. The principle is that targeted ransomware will look for individuals who have access to critical and valuable information, for example, a CEO or CFO of an organization.
If you are a business that has mitigating controls in place, and you are targeted by a successful attack, then it will be a matter of invoking the disaster recovery process. This will be based on the the businesses information classification criteria and management principles.
Every organisation will have information that is deemed to be valuable – and without access to this information, a business could suffer inadvertent loss and eventually begin losing money. Therefore, the disaster recovery controls around the businesses critical information will need to allow for that data to be readily available within a certain timeframe, for business to continue.
So, what is best practice for Ransomware attacks?
- Back Up is key
The best defense against ransomware is to reduce your vulnerability in the first place. This means backing up the company’s critical and valuable information on a regular basis. Hence, if your businesses become a target of a ransomware attack, having to pay the ransom may not bear consideration as the business will have access to its valuable information that has been backed up. It is important that the companies maintain offline back-ups so that the back-ups are not readily accessible to an attacker.
- Trusted sources
Businesses should exercise good email and website safety practices – ensuring that individuals download attachments, click URLs or execute programs only from trusted sources.
- Trust warnings
When you get a security message from a web browser, take heed of it.
- Administrator Rights
Manage administrator rights accordingly. Many businesses still use the default administrator account on their network. Instead you should delete or rename the administrator account or create an account with administrator privileges.
- Educate! Educate! Educate
It should be an executive management imperative for businesses to educate their employees about the challenges around ransomware making staff aware of any security issue that arises, or is currently topical – this could be ransomware, PoPI, encryption – your people need to be aware of it.
In summary, organisations should prepare themselves for the likelihood that they may be targeted by a ransomware attacker by implementing the mitigating controls of back-up and more especially user awareness. If they maintain the vigilance outlined above they will be able to reduce the impact of the ransomware as recently evidenced by the WannaCry attack that was so effective.
Notre Dame, Scoop Makhathini, GoT, top week in search
From fire disaster to social media disaster, the top Google searches this week covered a wide gamut of themes.

5G smartphones to hit 5M sales in 2019
According to the latest research from Strategy Analytics, global smartphone shipments will reach a modest 5 million units in 2019. Early 5G smartphone models will be expensive and available in limited volumes. Samsung, LG and Huawei will be the early 5G smartphone leaders this year, followed by Apple next year.
Ken Hyers, Director at Strategy Analytics, said, “We forecast global 5G smartphone shipments will reach a modest 5 million units in 2019. Less than 1 percent of all smartphones shipped worldwide will be 5G-enabled this year. Global 5G smartphone shipments are tiny for now, due to expensive device pricing, component bottlenecks, and restricted availability of active 5G networks.”
Ville Petteri-Ukonaho, senior analyst at Strategy Analytics, added, “Samsung will be the early 5G smartphone leader in the first half of 2019, due to initial launches across South Korea and the United States. We predict LG, Huawei, Xiaomi, Motorola and others will follow later in the year, followed by Apple iPhone with its first 5G model during the second half of 2020. The iPhone looks set to be at least a year behind Samsung in the 5G smartphone race and Apple must be careful not to fall too far behind.”
Neil Mawston, executive director at Strategy Analytics, added, “The short-term outlook for 5G smartphones is weak, but the long-term opportunity remains huge. We forecast 1 billion 5G smartphones to ship worldwide per year by 2025. The introduction of 5G networks, by carriers like Verizon or China Mobile, opens up high-speed, ultra-low-latency services such as 8K video, streaming games, and augmented reality for business. The next big question for the mobile industry is how much extra consumers are really willing to pay, if anything, for those emerging 5G smartphones and services.”
