Mirai, the ever-morphing malware behind devastating DDoS attacks, has also disrupted two U.K. broadband providers. The malware's framework is becoming a platform for attacks against IoT devices.
Deutsche Telekom says 900,000 customers were unable to access the internet after their routers were infected with malware. Researchers say it's a modified version of Mirai - code for building an internet-of-things botnet.
DDoS attacks apparently were directed at the small west African country of Liberia from the same botnet that struck networking services provider Dyn. Were the attacks just a test for a bigger attack to come?
The malware-infected IoT army that disrupted domain name server provider Dyn was composed of, at most, 100,000 devices, the company estimates in an after-action report. But claims that the attacks peaked at 1.2 Tbps remain unconfirmed.
Chinese manufacturer Xiongmai will recall up to 10,000 webcams in the wake of the IoT-powered DDoS attacks that pummeled DNS provider Dyn. But information security experts say that only a more resilient internet will blunt future attacks.
Massive DDoS attacks, targeting DNS provider Dyn, have triggered widespread internet disruptions. Security intelligence firm Flashpoint says the attacks have been perpetrated at least in part via a botnet of Mirai-infected internet of things devices.
A new cyberattack trend report from Europol notes that while online criminals continue to refine their capabilities, old and unsophisticated attacks too often still succeed, thanks to poor digital hygiene and a lack of security by design and user awareness.
The cybercrime sector involves a rapidly growing services economy that provides everything from bulletproof hosting and stresser/booter DDoS on demand, to ransomware-as-a-service and sites that offer to launder bitcoins via a process known as tumbling.
Despite police disrupting alleged DDoS extortion gangs such as DD4BC, inexpensive stresser/booter services have enabled copycats to continue these attacks, says Akamai's Martin McKeay. Here's how organizations can defend themselves.
The nature of sophisticated fraud is changing, argues NPCI's Bharat Panchal. He shares experiences from his sector to support this idea, and he shares insights on how this will affect the security practitioner roles.
Law enforcement agencies have scored some notable botnet-busting successes, disrupting malicious infrastructure and arresting botnet-using gangs. But cybercriminals are adapting, one top EU cybercrime investigator warns.
Cyber-extortion attacks, especially those involving DDoS gangs that threaten disruptions unless the targeted organization pays a bitcoin ransom, are on the rise. Experts describe how organizations should respond to - and resist - these attacks.
Extortion campaigns waged by cybercriminals are expected to become more damaging in 2016, putting additional pressure on CISOs to enhance protection of internal networks and educate employees about extortionists' techniques, says iSight Partner's John Miller.
Will this week's arrests of a "main target" and another suspect tied to the distributed denial-of-service extortion group known as DD4BC deter copycats from waging similar schemes? Experts weigh in.
European police have arrested a "main target" as part of a previously undisclosed law enforcement effort, dubbed Operation Pleiades, against the distributed denial-of-service attack gang called DD4BC, or "DDoS for Bitcoin."
