WASHINGTON (AP) – U.S. authorities on Thursday issued an additional alarm about intrusion into computer systems around the world, with officials suspecting the nation’s civil cyber security agency has been warned by Russian hackers that it poses a “serious” threat to government and private networks. .
The Cybersecurity and Infrastructure Security Agency said in its most detailed comments so far that the intrusion had tampered with government agencies, as well as “complex structures” that were difficult to detect in a sophisticated attack and would be difficult to undo.
The CIS did not say which agencies or infrastructure were breached or what information was taken in the attack which it said earlier appeared to have started in March.
“This threatening actor has demonstrated sophistication and intricate tradecraft in these intruders,” the agency said in an unusual warning. “CISA expects that removing the warner from the intrusive environment will be very complex and challenging.”
The agency had previously said that the criminals used network management software from Solarwinds T, based in Texas. o Intrusion into a computer network. His new warning said attackers could also use other methods.
A U.S. official has previously told the Associated Press that Russia-based hackers are suspected, but neither the CISA nor the FBI has publicly stated who is responsible.
Other U.S. The official, speaking on condition of anonymity to discuss the topic of conversation Thursday, said the hack was serious and extremely damaging although the Trump administration is not yet willing to publicly blame anyone for it.
This seems to be the worst hacking case in US history, the official said. “They got into everything.”
The administration is working on the assumption that most, if not all, were compromised with government agencies, but the extent of the damage is not yet known, the official said.
Asked if Russia was behind the attack, the official said: “We believe so. We haven’t said that publicly yet because it’s not 100% confirmed. “

Officials raising alarm about intrusion into computer systems around the world suspect it was carried out by Russia.
The Homeland Security Department’s Cyber Security Unit said Thursday that the hack “poses a serious threat to the federal government and state, local, tribal, and regional governments, as well as critical infrastructure organizations and other private sector organizations.”
These were highly detailed comments from the Cybersecurity and Infrastructure Agency, as reports emerged this week that government agencies, including the Treasury and Commerce Department, were among those whose secure data and emails were hacked by sophisticated hacks.
The CISA also warned that it would be difficult to remove the malware introduced by the network software. “Removing this threatening actor from the warning environment will be very complex and challenging for organizations,” the agency said.
