Hackers use DNS tunneling for network scanning, tracking victims

Threat actors are using Domain Name System (DNS) tunneling to track when their targets open phishing emails and click on malicious links, and to scan networks for potential vulnerabilities. DNS tunneling is the encoding of data or commands that are sent and retrieved via DNS queries, essentially turning DNS, a fundamental network communication component, into a covert communications channel. The threat actors encode the data in various ways... READ MORE...

Only one-third of firms deploy safeguards against generative AI threats, report finds

Generative AI gives attackers an edge over cyber defenders, according to a Splunk survey of security experts. Cyberattacks annually soared 26% on average from 2017 until 2023, Moody's Investors Service said last month, citing University of Maryland data. "This number is likely to be understated since organizations are often not required to report cyberattacks." As cybersecurity risks rise, generative AI will likely favor attackers over the short-to-medium term, Moody's said. READ MORE...

Heartbleed: When Is It Good to Name a Vulnerability?

Ten years have passed since Heartbleed was first identified, but the security industry is still grappling with the question of branded vulnerabilities and naming vulnerabilities appropriately. Back in April 2014, researchers uncovered a serious vulnerability in OpenSSL. There are many serious vulnerabilities, but this one was particularly bad, with security expert Bruce Schneier calling it "catastrophic." On his blog, Schneier wrote, "On the scale of 1 to 10, this is an 11." READ MORE...
