Brazil has noticed an increase in cyberattacks through brute force due to the accumulation of remote work, according to a new report on security threats in the first six months of 2020.
More than 2. 6 billion cyberattacks were recorded through the Fortinet cybersecurity company from January to June, out of a total of 15 billion in Latin America and the Caribbean.
According to the report, there has been a “significant increase” in brute force attacks: the practice of continuously guessing imaginable combinations of login data through automated means, until the correct type of access data is discovered.
The increase in the adoption of remote paints has revived the interest of cybercriminals in this type of attack, according to Alexandre Bonatti, engineering director of Fortinet Brazil: “[Attackers] a giant number of misconfigured Remote Desktop Protocol servers, which facilitate invasions,” he noted.
An example of those attacks discussed through the cybersecurity company in the report is SSH. Connection. Brute. Force, which consists of several Secure Shell (SSH) queries designed to perform a brute force SSH connection, was introduced about 20 hundred times in 10 seconds.
For other types of cyberattacks, Covid-19-related phishing campaigns are not yet unusual in Brazil, but they do not occur as intensely as the pandemic began: those attacks peaked in April, according to Fortinet’s report.
According to another phishing report, published through Kaspersky in April 2020, there was a 124% increase in this type of scam in Brazil at the beginning of the pandemic.
This month’s phishing expansion was due to an accumulation of malicious messages sent via WhatsApp taking credit for the Covid-19 situation: cybercriminals would send messages intended to steal the user’s non-public knowledge to be used in other attacks, or force them. patients to download valid applications, so they can be paid for through associated programs.
Another report published in March 2020 through Trend Micro placed Brazil third in the global ranking of cyberthreat of email and ransomware, the United States and China, and ranked Brazil as the third largest country in the world with the highest number of ransomware attacks. in 2019 the United States and India.
