The source code for the Mirai botnet has been updated to launch DDoS amplification/reflection attacks, although so far that capability hasn't been used, says Gary at Arbor Networks. Even so, DDoS defense planning remains essential.
Apache Struts 2 users are being warned to upgrade immediately, after attackers began targeting a zero-day flaw in the widely used, open source Java EE platform. Some attacks deactivate firewalls on vulnerable Linux systems and install DDoS or BillGates malware, amongst other malicious code.
When it comes to massive DDoS attacks powered by the likes of a Mirai botnet, "the sky is not falling," says ESET security researcher Cameron Camp. But organizations do need to prepare - and here's where to start.
New ransomware circulating via BitTorrent is disguised as software that purports to allow Mac users to crack popular Adobe and Microsoft applications. Separately, new ransomware calling itself Trump Locker appears to be the previously spotted VenusLocker ransomware in disguise.
At the request of German authorities, British police have arrested a suspected hacker involved in last year's disruption of 1 million Deutsche Telekom customers' routers via Mirai malware, which targets default credentials on internet-connected devices.
Responding to disruptive data breaches, dealing with Mirai botnets, hacking back and the need for enterprises to segment their backup environments were just some of the topics dominating this year's RSA Conference in San Francisco.
The uptick of ransomware and other cyberattacks in the healthcare sector has prompted healthcare provider RWJBarnabas Health to make a number of important moves to help prevent, detect and respond to breaches, says CISO Hussein Syed.
Donald Trump's inauguration has led to a call for a mass online protest of questionable legality designed to "occupy" the White House website. Separately, Anonymous has threatened Trump with "regret" and promised to unearth compromising information.
Yet another power blackout in Ukraine was the result of attackers striking via spear-phishing emails and malware, researchers have confirmed. Ukraine's president blamed the campaign on Russia and said it disrupted a number of critical infrastructure targets.
A list of "super user" passwords - and a default username - now circulating online appears to allow unauthorized access to some webcam video streams, security researchers warn. If confirmed, it would be yet another massive internet of things security failure by a device manufacturer.
Hacks sponsored by nation-states and attacks fueld by IoT-powered botnets are just some of the daunting threats we will see in 2017, says cybersecurity thought leader Tom Kellermann. What are his top predictions, and how should security leaders respond?
Over the years, HHS has released several guidance documents, but all are weak and without mandates as it relates to identity management and authentication of entities accessing protected health information. Guidance typically includes words like "may" and "should," but rarely include words like "shall" or "must."
Over the past two years, DDoS attacks have grown in strength and in purpose - they are often used now as a tool of extortion, says Richard Meeus of security vendor NSFOCUS. How should security leaders prepare to respond to these strikes?
