A computer vulnerability discovered last year in a ubiquitous piece of software is an "endemic" problem that will pose security risks for potentially a decade or more, according to a new cybersecurity panel created by President Joe Biden.
The Cyber Safety Review Board said in a report Thursday that while there hasn't been a sign of any major cyberattack due to the Log4j flaw, it will still "be exploited for years to come."
"Log4j is one of the most serious software vulnerabilities in history," the board's chairman, Department of Homeland Security Under Secretary Rob Silvers, told reporters Wednesday.
The Log4j flaw, made public late last year, lets internet-based attackers easily seize control of everything from industrial control systems to web servers and consumer electronics. The first obvious signs of the flaw's exploitation appeared in Minecraft, a hugely popular online game owned by Microsoft.
The flaw's discovery prompted urgent warnings by government officials and massive efforts by cybersecurity professionals to patch vulnerable systems.
The board said Thursday that "somewhat surprisingly" the exploitation of the Log4j bug had occurred at lower levels than experts predicted. The board also said that it was unaware of any "significant" Log4j attacks on critical infrastructure systems but noted that some cyberattacks go unreported.
The board said future attacks are likely in large part because Log4j is routinely embedded with other software and can be hard for organizations to find running in their systems.
"This event is not over," Silvers said.
Log4j, written in the Java programming language, logs user activity on computers. Developed and maintained by a handful of volunteers under the auspices of the open-source Apache Software Foundation, it is extremely popular with commercial software developers.
A security researcher at the Chinese tech giant Alibaba notified the foundation on Nov. 24. It took two weeks to develop and release a fix. Chinese media reported that the government punished Alibaba for not reporting the flaw earlier to state officials.
The board said Thursday it found "troubling elements" with the Chinese government's policy toward vulnerability disclosures, saying it could give Chinese state hackers an early look at computer flaws they could use for nefarious means like stealing trade secrets or spying on dissidents. The Chinese government has long denied wrongdoing in cyberspace and told the board that it encourages improved information sharing on software vulnerabilities.
The board offered a number of recommendations on mitigating the fallout of the Log4j flaw as well as improving cybersecurity generally. That includes the suggestion that universities and community colleges make cybersecurity training a required part of computer science degree and certification programs.
The Cyber Safety Review Board is modeled after the National Transportation Safety Board, which reviews plane crashes and other major accidents, and was mandated by an executive order Biden signed last May. The 15-member board is made up of FBI, National Security Agency and other government officials as well as people from the private sector. Some supporters of the new board criticized DHS for taking so long to get it up and running.
Biden's executive order directed the board to conduct its first review on the massive Russian cyber espionage campaign known as SolarWinds. Russian hackers were able to breach several federal agencies, including accounts belonging to top cybersecurity officials at DHS, though the full fallout from that campaign is still unclear.
Silvers said DHS and the White House agreed that reviewing the Log4j flaw was a better use of the new board's expertise and time.

Statements by DHS/CSRB Officials
At this critical juncture in our nation's cybersecurity, when our ability to handle risk is not keeping pace with advances in the digital space, the Cyber Safety Review Board is a new and transformational institution that will advance our cyber resilience in unprecedented ways. The CSRB's first-of-its-kind review has provided us — government and industry alike — with clear, actionable recommendations that DHS will help implement to strengthen our cyber resilience and advance the public-private partnership that is so vital to our collective security. —Secretary of Homeland Security Alejandro Mayorkas
The Cyber Safety Review Board has established itself as a new, innovative, and enduring institution in the cybersecurity ecosystem. Never before have industry and government cyber leaders come together in this way to review serious incidents, identify what happened, and advise the entire community on how we can do better in the future. Our review of Log4j produced recommendations that we are confident can drive change and improve cybersecurity. —CSRB Chair and DHS Under Secretary for Policy Robert Silvers
Cybersecurity is a shared responsibility, which is why it is so critical that the CSRB is a private-public partnership. We hope that the independent fact-finding, analysis, and conclusions reached, as well as the recommendations, are taken in earnest as lessons-learned and instructive actions for both the near and long-term. —CSRB Deputy Chair Heather Adkins
The CSRB is a remarkable public-private initiative that has produced an important blueprint for CISA — our nation's civilian cyber defense agency — to meaningfully increase cybersecurity resilience and preparedness across our country. I look forward to implementing the CSRB's impactful recommendations and thank the members for their time and thoughtful counsel. —Cybersecurity and Infrastructure Security Agency Director Jen Easterly
