What is a cyber attack?
As the emergence of the Internet has increased the risk of cyber attacks, new techniques have emerged and others that seemed forgotten have been increasing over the years, these cyber attacks have affected millions of users.
There are no defined boundaries for unauthorized access, illegal access to information has been scaled directly in proportion to threats that are increasingly diverse and complex.
The objectives of the attacks have expanded and include not only government institutions, but also critical infrastructure, very specific companies and industries.
This requires stronger measures, even when most government institutions and large corporations have created tools to keep information secure, this is not enough because the methods of the attacks have become increasingly evasive and this results in great difficulties in detecting them .
Cyber attacks go through different stages: espionage , intrusion , internal diffusion , attack and elimination of tractions of activity . It is becoming increasingly difficult to detect these stages. These attacks are already one of the main threats to the security of companies worldwide, because one of the multiple consequences they generate is the loss of information.
In 2017, data loss from these attacks caused an approximate loss of 3.62 million. Cybercriminal attacks and malicious code attacks are the most expensive and can generate losses of an average of $ 156 per business record. The five countries that suffered the most attacks were the United States, with 55.9% of the attacks; United Kingdom with 11%; Holland with 6.5%; Japan with 6.4% and Canada with 2.6% of the attacks. The five countries from which most attacks occurred were: China, with 64.1% of the attacks; South Korea, with 8.1% of attacks; Vietnam with 5.9%, United States 3.5% and Taiwan with 2.6% of the attacks.
What is Hotmail and what is Outlook?
Hotmail is the name of an email account provider that is free and paid for, it was founded in 1995 by Bhatia and Smith, it was the first webmail system , later in 1997 it was acquired by Microsoft for a value of four hundred million US dollars (US $ 400,000,000.00) and added to the MSN network , adding more than 30 million users, making it the largest webmail service in the world.
Then it switched to Live and is now called Outlook.com . This Outlook works under the Windows platform and was developed by Microsoft to help people, whether individuals, governments, public or private companies who needed an email manager. Microsoft migrated accounts automatically, including users who have maintained them since 1996. The role of Outlook is to receive and send e-mails, as well as to store incoming and outgoing messages.
The Hotmail e-mail service has been providing its work for over twenty years and has been adapted to the needs of users.
Cyber attacks against Hotmail and Outlook
When the Internet became popular, Microsoft suffered an attack that thousands of users were affected, this attack consisted of a virus that made users believe that some known contact was who was sending the attachment. The virus was automatically sent to 15 contacts and was therefore spreading at an impressive rate. In May 2011, Microsoft discovered that strangers accessed some accounts.
A security company called Trend Micro confirmed that the attackers were using a hidden program in an email. This program took advantage of a bug on Microsoft websites to redirect copies of all emails received by the owner to an account controlled by the attacker.
This was detected in more than a thousand accounts and immediately Microsoft solved the problem before Trend Micro published the discovery. When Microsoft conducted the relevant investigations, it noted that this scheme had been in use since July 2009 and had affected the Uighur ethnic group and Tibetan leaders. The attackers were also able to access emails from human rights defenders, African and Japanese diplomats and many others.
Microsoft is said to have been aware of these attacks and acknowledged that it did not warn users that they suffered email theft. However they announced after everything happened, they will always notify that they know that a government has illegally accessed a user’s data.
