As countries pursue national 5G rollouts, an unwanted security challenge has intensified: Some extremists have been vandalizing or even firebombing transmitter masts, driven by conspiracy theories suggesting not only that 5G poses a public health risk, but that it also helps cause COVID-19.
Can you "big tech" a way out of a pandemic? Many governments around the world are trying, and Australia is joining the herd with a contact tracing app. But Australia has a splotchy record of large government tech projects, including in health, that may result in low voluntary adoption of an app.
Microsoft issued patches for three zero-day vulnerabilities as part of its most recent Patch Tuesday update. The software giant had previously warned users about two vulnerabilities in the Adobe Type Manager Library that were being exploited in the wild.
The U.K. government says it's prepping a contact-tracing app in an attempt to help contain COVID-19. But a leading cybersecurity expert argues that the proposal amounts to little more than "do-something-itis" and urges a focus, instead, on expanded testing as well as ventilator production.
Gartner analyst Avivah Litan says China is attempting to leverage blockchain technology in the country's COVID-19 recovery. What are the benefits and concerns of this approach, and how should it shape the future use of blockchain?
Cybercrime groups and nation-state hacking gangs are continuing to exploit the COVID-19 pandemic to further their aims, U.K. and U.S. security agencies warn in a joint alert. While overall attack levels haven't increased, they say, "the frequency and severity of COVID-19-related cyberattacks" looks set to surge.
The operator of a newly discovered botnet dubbed "Dark Nexus" is offering cybercriminals access to an array of capabilities, include the ability to launch DDoS attacks on demand, according researchers at Bitdefender.
For nearly a decade, five hacking groups with apparent links to the Chinese government have targeted vulnerable Linux servers that make up the backend IT infrastructure of thousands of companies and organizations around the world, according to a research report from BlackBerry.
Zero-day exploits are increasingly a commodity that advanced persistent threat groups can purchase and use to wage attacks, according to a report from security firm FireEye. The report says the number of attacks leveraging such exploits grew last year.
As the COVID-19 outbreak has intensified, so too has cybercrime, including ransomware, Interpol, the international crime-fighting agency, warns. Despite some gangs claiming to no longer be targeting healthcare organizations, experts have seen "no abatement, empathy or free decryptor" from any of them.
Researchers at Boston University have written a research paper that proposes creating a smartphone app that uses short-range transmission technologies that can inform users if they have been in close proximity to a person infected with COVID-19 - while maintaining privacy.
Hackers are targeting Chinese government agencies and their employees by taking advantage of zero-day vulnerabilities in VPN servers to plant backdoors and other malware, researchers at the Chinese security firm Qihoo 360 report.
When it comes to threat hunting, what are the complementary uses of SIEM and EDR technologies? What are the unique use cases for each, and how can they coexist? Sam Curry of Cybereason shares tips in advance of a virtual roundtable discussion.
True predictive analysis is difficult - and it sometimes takes years of learning and data modeling to get it right, says Derek Manky, chief of security insights and global threat alliances at Fortiguard Labs.
As global enterprises get their arms around supporting and securing a near-total remote workforce, their digital adversaries are adapting - and so is the role of deception technology. Carolyn Crandall of Attivo Networks discusses how deception can help mitigate new risks.
