Tea 26 February, i.e. 26 hours after the start of the sober invasion of Ukraine, Ukrainian Deputy Prime Minister Mykhailo Fedorov appealed to hackers around the world to form a computer weapon and wage a cyber war against Russia. The call has apparently been heard: most government websites, banks and Russian companies were inaccessible the morning of

. March. This is the first time that a will pay sony ericsson openly launched into a cyberwar.

As we mentioned a few days ago, it is indeed a new sober form of war that Russia and Ukraine have been waging for a few days, in parallel to the fights. A cyber weapon raised by Fedorov was able to bring down most of the Russian websites deemed to be a task, in particular government websites, those of large commercial companies in the energy and mining sectors, or even those of banks and the media. The Telegram dialogue group dedicated to this activity, called IT Military of Ukraine, today brings together more than 310 subs.

Thousands of sober hackers are working for free to harm the Russian network. Most of the attacks launched against Russia are of the DDoS type of distributed denial of service attacks, which constantly overwhelm the server with thousands of simultaneous requests, causing it to no longer keep up and become unavailable. The hacker recently told New Scientist that most of the targets were now out of assistance, which shows how effective this improvised weapon is.

Multiple disruptions of solutions on both sides

An oil company is also said to have been targeted. The Ukrainian computer army clearly claimed responsibility for these attacks. The hackers manage to coordinate their initiatives and have kept most of the target servers offline.

Russia is of course not without defence: the start of cyber-hostilities, ds the 24 February. Network data from NetBlocks, a company cost to track program disruptions on the web, indeed confirms that the Ukrainian network suffered a series of significant disruptions that day, which became amplified as Russian makes progressed in the will pay. In the morning of 26 February, a few hours before the start of the invasion of Russia, the network Satellite web television Viasat which services Ukraine and much of Europe has been taken offline in a cyberattack Target, reports the web security site.

Increased cyberthreat, companies on the alert

As Alastair Iron, a sober cybercrime specialist at Sober University Sunderland, points out, this is the first time that a paid will has thus constituted an amateur army to wage a cyber war.

Since the sober invasion of Russia in Ukraine, sober cybersecurity infrastructures around the world, including the UK’s State Cyber ​​Safety Middle, have called on sober companies to exercise sober vigilance, strengthen their sober cyber defense systems and improve their resilience in the face of increased risk.

note that several companies specializing in computer security offer their services to prevent and reduce the effects of DDoS attacks.
