This massive security flaw has the internet freaked out
BOSTON (AP) — Security pros say it’s one of the worst computer vulnerabilities they’ve ever seen. They say state-backed Chinese and Iranian hackers and rogue cryptocurrency miners have already seized on it.
The Department of Homeland Security is sounding a dire alarm, ordering federal agencies to urgently eliminate the bug because it’s so easily exploitable — and telling those with public-facing networks to put up firewalls if they can’t be sure. The affected software is small and often undocumented.
Detected in an extensively used utility called Log4j, the flaw lets internet-based attackers easily seize control of everything from industrial control systems to web servers and consumer electronics. Simply identifying which systems use the utility is a prodigious challenge; it is often hidden under layers of other software.
The top U.S. cybersecurity defense official, Jen Easterly, deemed the flaw “one of the most serious I’ve seen in my entire career, if not the most serious” in a call Monday with state and local officials and partners in the private sector. Publicly disclosed last Thursday, it’s catnip for cybercriminals and digital spies because it allows easy, password-free entry.
The Cybersecurity and Infrastructure Security Agency, or CISA, which Easterly runs, stood up a resource page Tuesday to help erase a flaw it says is present in hundreds of millions of devices. Other heavily computerized countries were taking it just as seriously, with Germany activating its national IT crisis center.
A wide swath of critical industries, including electric power, water, food and beverage, manufacturing, and transportation, were exposed, said Dragos, a leading industrial control cybersecurity firm. “I think we won’t see a single major software vendor in the world — at least on the industrial side — not have a problem with this,” said Sergio Caltagirone, the company’s vice president of threat intelligence.
Eric Goldstein, who heads CISA’s cybersecurity division, said Washington was leading a global response. He said no federal agencies were known to have been compromised….
