Researchers at Mnemonics Labs have found a vulnerability in the server name indication, or SNI, of the TLS Client Hello extension. Exploitation could enable attackers to bypass the security protocol of many security products, leading to stealthy exfiltration of data, researchers say.
Andy Jenkinson of Cybersec Innovation Partners has found an alarming number of flaws and misconfigurations in websites and web servers run by some of the biggest players in government, healthcare and even cybersecurity. He discusses this pressing issue in the latest episode of "Cybersecurity Unplugged."
The World Bank has launched a cybersecurity fund for low- and middle-income nations to support public sector efforts to conduct cybersecurity maturity assessments, offer technical assistance and support training and staff development.
Scientists from the University of Maryland and the University of Colorado Boulder say they have discovered a new way that attackers could launch reflected denial-of-service amplification attacks over TCP by abusing middleboxes and censorship infrastructure.
Phishing attacks have come a long way from the spray-and-pray emails of just a few decades ago. Now they’re more targeted, more cunning and more dangerous. And this enormous security gap leaves you open to business email compromise, session hijacking, ransomware and more.
