Most readers here have likely heard or read various prognostications about the impending doom from the proliferation of poorly-secured “Internet of Things” or IoT devices. Loosely defined as any gadget or gizmo that connects to the Internet but which most consumers probably wouldn’t begin to know how to secure, IoT encompasses everything from security cameras, routers and digital video recorders to printers, wearable devices and “smart” lightbulbs.
Throughout 2016 and 2017, attacks from massive botnets made up entirely of hacked IoT devices had many experts warning of a dire outlook for Internet security. But the future of IoT doesn’t have to be so bleak. Here’s a primer on minimizing the chances that your IoT things become a security liability for you or for the Internet at large.
A U.K. man who pleaded guilty to launching more than 2,000 cyberattacks against some of the world’s largest companies has avoided jail time for his role in the attacks. The judge in the case reportedly was moved by pleas for leniency that cited the man’s youth at the time of the attacks and a diagnosis of autism.
The U.S. Justice Department on Tuesday unsealed the guilty pleas of two men first identified in January 2017 by KrebsOnSecurity as the likely co-authors of Mirai, a malware strain that remotely enslaves so-called “Internet of Things” devices such as security cameras, routers, and digital video recorders for use in large scale attacks designed to knock Web sites and entire networks offline (including multiple major attacks against this site).
Last week we looked at reports from China and Israel about a new “Internet of Things” malware strain called “Reaper” that researchers said infected more than a million organizations by targeting newfound security weaknesses in countless Internet routers, security cameras and digital video recorders (DVRs). Now some botnet experts are calling on people to stop the “Reaper Madness,” saying the actual number of IoT devices infected with Reaper right now is much smaller.
Arbor Networks said it believes the current actual size of the Reaper botnet fluctuates between 10,000 and 20,000 bots total. Arbor notes that this can change any time.
It’s been just over a year since the world witnessed some of the world’s top online Web sites being taken down for much of the day by “Mirai,” a zombie malware strain that enslaved “Internet of Things” (IoT) devices such as wireless routers, security cameras and digital video recorders for use in large-scale online attacks.
Now, experts are sounding the alarm about the emergence of what appears to be a far more powerful strain of IoT attack malware — variously named “Reaper” and “IoTroop” — that spreads via security holes in IoT software and hardware. And there are indications that over a million organizations may be affected already.
Reaper isn’t attacking anyone yet. For the moment it is apparently content to gather gloom to itself from the darkest reaches of the Internet. But if history is any teacher, we are likely enjoying a period of false calm before another humbling IoT attack wave breaks.
A half dozen technology and security companies — some of them competitors — issued the exact same press release today. This unusual level of cross-industry collaboration caps a successful effort to dismantle ‘WireX,’ an extraordinary new crime machine comprising tens of thousands of hacked Android mobile devices that was used this month to launch a series of massive cyber attacks.
Experts involved in the takedown warn that WireX marks the emergence of a new class of attack tools that are more challenging to defend against and thus require broader industry cooperation to defeat.
Last month, KrebsOnSecurity identified U.K. citizen Daniel Kaye as the likely real-life identity behind a hacker responsible for clumsily wielding a powerful botnet built on Mirai, a malware strain that enslaves poorly secured Internet of Things (IoT) devices for use in large-scale online attacks. Today, a German court issued a suspended sentence for Kaye, who now faces related cybercrime charges in the United Kingdom.
Axis Communications — a maker of high-end security cameras whose devices can be found in many high-security areas — recently patched a dangerous coding flaw in virtually all of its products that an attacker could use to remotely seize control over or crash the devices.
The problem wasn’t specific to Axis, which seems to have reacted far more quickly than competitors to quash the bug. Rather, the vulnerability resides in open-source, third-party computer code that has been used in countless products and technologies (including a great many security cameras), meaning it may be some time before most vulnerable vendors ship out a fix — and even longer before users install it.
In February 2017, authorities in the United Kingdom arrested a 29-year-old U.K. man on suspicion of knocking more than 900,000 Germans offline in an attack tied to Mirai, a malware strain that enslaves Internet of Things (IoT) devices like security cameras and Internet routers for use in large-scale cyberattacks. Investigators haven’t yet released the man’s name, but news reports suggest he may be better known by the hacker handle “Bestbuy.” This post will follow a trail of clues back to one likely real-life identity of Bestbuy.
A 20-year-old man from the United Kingdom was sentenced to two years in prison today after admitting to operating and selling access to “Titanium Stresser,” a simple-to-use service that let paying customers launch crippling online attacks against Web sites and individual Internet users.
Adam Mudd of Herfordshire, U.K. admitted to three counts of computer misuse connected with his creating and operating the attack service, also known as a “stresser” or “booter” tool. Services like Titanium Stresser coordinate so-called “distributed denial-of-service” or DDoS attacks that hurl huge barrages of junk data at a site in a bid to make it crash or become otherwise unreachable to legitimate visitors.
