Be careful when resting at home

You get home after work. Tired of an arduous day of work, you’re going to relax and watch your favorite series. Before that, you verify that your router is not one that is full of holes. Relieved by that fact, you connect the wifi willing to see your mail. However, the fear that you open a file that you should not, or click on an unfortunate link will overwhelm you. The danger is just around the corner and any missteps can be fatal.

But what threat is more likely to catch me off guard? Vulnerabilities are everywhere and although we must be alert to all kinds of attacks, there are some of them that are more willing to take our data. For example: phishing. According to the latest study by Helpness Security, three out of four malware attacks are caused by phishing.

These phishing attacks have as main objectives the governments (65%) and the professional services (25%) above the rest of sectors. As for the countries most affected by this threat, we would find the United States first, followed by the Netherlands and France.

The report also reveals that just 25 passwords accounted for nearly 33% of all authentication attempts against NTT Security honeypots last year. Over 76% of log on attempts included a password known to be implemented in the Mirai botnet – a botnet comprised of IoT devices, which was used to conduct, what were at the time, the largest ever distributed denial of service (DDoS) attacks. Thus, it is curious to note that DDoS attacks accounted for less than 6% of attacks worldwide, although in Asia and Australia are more popular than in other countries.

"We identified more than six billion attempted attacks during the 12 months, which means around 16 million attacks a day," said Steven Bullitt, Vice President Threat Intelligence & Incident Response, GTIC, NTT Security. On the other hand, the finance sector turns out to be the most attacked at the global level, since it always appeared on the podium of all geographic regions analyzed. In second position we would have the governmental sector (14%) and finally, the bronze of more attacked sector would belong to the one of the manufacture.

Besides, the study leaves us other interesting data:

  • Top attack source countries: United States (63%), United Kingdom (4%), China (3%).
  • 32% of organizations had a formal incident response plan up from an average of 23% in previous years.
  • 59% of all incident response engagements were in the top four industries – health care (17%), finance (16%), business and professional services (14%), and retail (12%).
  • Over 60% of incident response engagements were related to phishing attacks.
  • Incident engagements related to ransomware were the most common incidents (22%).
  • 56% of all incidents in finance organizations were related to malware.
  • 50% of all incidents in health care organizations were related to ransomware incidents.
With the visibility of 40 percent of global Internet traffic, NTT Security summarizes data for more than 3.5 billion records and 6.2 billion attacks for the 2017 Global Threat Intelligence Report (GTIR). The analysis is based on log data, events, attacks, incidents and vulnerabilities.

At home we find our place of comfort and security, but that does not mean that we have to raise our guard. The attacks are constant and if we do not worry, we can get affected. Anyway, do not be paranoid. Check and secure your passwords, be careful where you click and keep your software updated. Doing that, you will not make the cybercriminals work so easy.
