It’s no surprise that 2018 continued to bring an increase in fraud attacks and data security breaches, including those of Facebook and now Marriott. In the past two years, the average number of overall daily searches for keywords such as “personal information disclosure” and “hacker” have been fluctuating at a very high level. This indicates that cybersecurity and information security are no longer just a technical issue, but one that affects people’s livelihood.

With the general public’s focus shifting towards cyber security at an increasing rate, the onus is on security vendors to make their customers feel safe and secure moving forward into 2019 by being aware of what has passed, and what is to come. In 2019, we can expect to see the following emergences in security technology and trends:

Malicious Email Attacks are On the Rise

In recent years, malicious emails have become an important infection path for various malicious codes. Malicious mails use social engineering methods to trick users into opening a malicious attachment file or clicking a malicious website link, in a bid to infect the users with various viruses (such as encrypted ransomware or trojan software), thereby causing direct economic losses. In addition, malicious mail-based attacks against enterprises have become quite common and can bring great profits. Some attackers directly trick users into disclosing key information or performing transfer operations, resulting in serious economic losses. According to the statistics, Business Email Compromise (BEC) attacks have caused greater economic losses even than ransomware. We should expect to see this trajectory continue into 2019.

Expect Cryptominers to Spread

Various malicious cryptominers, represented by WannaMine, have started to be spread extensively – since the end of March, the number of cryptomining activities has risen sharply compared to the beginning of the year. In 2019, we should expect cryptominers to continue their trajectory of becoming increasingly active as they did in 2018. Among all cryptominers, WannaMine was the most active in 2017, responsible for more than 70% of all detected cryptomining activities. This virus was first detected at the beginning of 2018 by CrowdStrike and was named so because it is spread via the EternalBlue vulnerability like the notorious WannaCry.
