They can transform into a devastating war.
To know what the scope of an offense of this type will be, you just have to think about hospitals, finances or energy systems.
The control of these infrastructures rests on online programs and connections.
In order to prevent the ravages of a confrontation in computer networks, the United States and Taiwn carry out an unprecedented joint test between these two countries.
Taiwanese officials are receiving emails and text messages from
Phishing as part of a week-long cyber war drill.
The local government is co-host of the tests with the American Institute in Taiwn, which represents American interests on the island.
This organization explained that the focus was on the threats posed by "North Korea and other actors."
But Taiwn said earlier that most of the cyber attacks he suffers come from mainland China.
"Facing such attacks is like being in a battle every day," a Taiwanese official said last month.
The exercises are carried out until Friday and include attempts to hack government websites tricking workers into accepting emails or malicious communications.
Several private companies also participate in the drill.
"For Taiwn, mainland China is seen as one of the main sources of cyberattacks on the island," says Veerle Nouwens of the Royal Institute of Defense and Security Services in the United Kingdom.
China sees Taiwn as an inalienable part of its territory and insists that reunification is inevitable, something it is willing to defend with force if necessary, as Pekn threatened on several occasions.
"The CEO of the Taiwn Cyber Security Agency acknowledged that Taiwanese government networks receive approximately 30 million attacks a month, of which half are suspected to come from China," said Nouwens.
"However, regardless of the country of origin, strengthening cybersecurity is a growing priority for any government or private sector company," added the expert.
The most significant risk
The maneuvers officially began at an event organized by Microsoft.
The interim director of the AIT, Raymond Greene, described the evidence as a "new frontier" in cyber cooperation between Washington and Taipi.
"The greatest threats today are not the troops landing on the beach, but the efforts of evil actors to use the opening of our societies and networks against us," said Greene.
"In many ways, cyber threats are the most significant risk and affect us all."
What attackers normally seek, he adds, is to undermine democratic elections, compromise key infrastructure and paralyze financial operations.
Officials from other countries, including Australia, Indonesia and Japan, also participate in defying Taiwn's defenses.
The simulation is based on an international computer attack simulation conducted by the United States, known as "cyber storm", which takes place every two years.
According to the Global Taiwan Institute, the island had repeatedly asked to participate in the last event held in spring 2018, but was not invited.
"The announcement that the United States participate in the cyber drills of Taiwn this year reflects the deep security cooperation between the United States and the island and combines other ongoing efforts between the United States and Japan to strengthen cybersecurity cooperation," he wrote in a blog the executive director of the US-based institute, Russell Hsiao, last month.
For its part, China previously accused Taiwn of being involved in "infiltration and sabotage activities against the Chinese continent."
