BOSTON (AP) — Researchers at a cybersecurity firm say they have identified vulnerabilities in software widely used by millions of connected devices — flaws that could be exploited by hackers to penetrate business and home computer networks and disrupt them.
There is no evidence of any intrusions that made use of these vulnerabilities. But their existence in data-communications software central to internet-connected devices prompted the U.S. Cybersecurity and Infrastructure Security Agency to flag the issue in a bulletin.
Potentially affected devices from an estimated 150 manufacturers range from networked thermometers to “smart” plugs and printers to office routers and healthcare appliances to components of industrial control systems, the cybersecurity firm Forescout Technologies said in a report released Tuesday. Most affected are consumer devices including remote-controlled temperature sensors and cameras, it said.
In the worst case, control systems that drive “critical services to society” such as water, power and automated building management could be crippled, said Awais Rashid, a computer scientist at Bristol University in Britain who reviewed the Forescout findings.
In its advisory, CISA recommended that users take defensive measures to minimize the risk of hacking. In particular, it suggested cutting off industrial control systems from the internet and isolated from corporate networks.
The discovery highlights the dangers that cybersecurity experts often find in internet-linked appliances designed without much attention to security. Sloppy programming by developers is the main issue in this case, Rashid said.
Fixing the problems, which could afflict millions of impacted devices, is particularly complicated because they reside in so-called open-source software, code freely distributed for use and further modification. In this case, the issue involves fundamental internet software that manages communication between internet devices via a technology called TCP/IP. Read more from US News and World Report.
