The report says that Chinese hackers from the Hafnium group are allegedly behind the attack, and their targets are government and commercial enterprises, including banks, power plants, educational institutions, etc. It is assumed that in the final stages of the malicious campaign, the hackers managed to automate the process due to which, in the shortest possible time, thousands of other companies around the world were hacked.

«We are responding to assess and remediate the consequences. The threat persists and evolves, so we urge internet operators to take it very seriously.“, – the White House spokesman commented on this issue, thereby confirming the concern of the American authorities about the current situation.

A spokesman for information security company Volexity reported that the hafnium hacker group has been using a vulnerability in Exchange Server for several months to hack various organizations and companies. Initially, the number of victims was small, as the attackers did not want to attract attention to themselves, but later the campaign took on a different scale. It’s worth noting that the so-called cybersecurity crisis came just months after another massive campaign in which hackers injected malware into updates to SolarWinds’ products. As a result of that attack, attackers managed to break into nine US federal agencies and at least 100 companies.
