The information war started simultaneously, and the Ukrainian military received a large number of heart war messages and was attacked by DDoS

The second is to confuse cognitive types, such as pretending that Ukrainian officers and soldiers say “The commander of Kramatrosk has run away, the situation is very bad, and many of us have to dodge.” or “Derba Debaltseve’s troops and volunteers have been killed, we should flee!” Such messages try to confuse the morale of Ukrainian troops on the front lines.

There was also a text message pretending to be the central government of Kiev, which read, “Your account balance has been adjusted to 10 hryvnia (approximately TWD 9.50), and the country thanks you for your contribution to the anti-terrorist mission in the east.”

Because Russia has more advanced electronic warfare equipment, it can quickly locate and send text messages from the mobile phones of Ukrainian soldiers, and use the methods commonly used by fraud groups.

For example, first send “Leave, or you will die!” to the mobile phone of the Ukrainian army officer and soldier, and then send a message to the soldier’s family, telling them that “your son (husband) is dead,” and then call the soldier’s mobile phone when the line is busy, or immediately shelling The location of the mobile phone signal makes it impossible for the family to contact their relatives on the front line at the moment, causing panic in the rear.

Since yesterday, the Russian cyber army has carried out DDoS attacks on the Ukrainian government and military networks. With the influx of large-scale traffic in an instant, the network has been paralyzed. In the past few days, the Ukrainian Ministry of Foreign Affairs, the Ministry of Defense and many enterprises, banks website, often unavailable.

The UK’s National Cyber ​​Security Centre (NCSC) has warned that the Sandworm threat actor, a hacker group controlled by Russia’s military intelligence agency GRU (GRU), is focusing its cyberattacks on Ukraine.

Sandworm has used VPNFilter malware many times before, targeting unsuspecting routers or cloud hard drives on the corporate network. After hacking, the files are locked. Many European and American companies have been hit before, and were only recovered after being extorted by Sandworm for ransom. material.

NATO, to assist Ukraine in resisting the Russian cyber offensive, has dispatched a cyber army to Kiev consisting of experts from Poland, the Netherlands, Lithuania, Estonia, Croatia and Romania.

Although Ukraine itself is not as strong as Russia in electronic and information warfare, it has learned to use some techniques to confuse the enemy on the front line over the years.

For example, many Ukrainian front-line bunkers will hang the American flag, or deliberately use English for radio communication, pretending to be a member of the U.S. Navy SEAL or a member of the Green Flat Cap Special Forces, commanding operations on the front line, etc., to confuse the Ukrainian separatist forces or the Russian army. members, so that the other party does not dare to attack rashly.

At present, the Russian-Ukrainian war has officially started. It is expected that the Russian army will greatly increase the intensity of information warfare. The combat effect has yet to be confirmed by follow-up observation.
