It's been an unfortunately busy few weeks for Android vulnerabilities. Earlier in the month, we wrote about SonicSpy, a grandiose piece of malware that could gain an incredible amount of control over your device - including, of course, being able to record your audio. Just last week, we followed-up with another story talking about the 500 apps Google obliterated from the Play Store that bundled an exploited ad network. Today, WireX is the name of the game, a piece of malware whose sole purpose is to turn our innocent mobile devices into a DDoSing bot network. On August 17, WireX hit many content...

There are lots of obvious examples of how IoT (Internet of Things) connected and smart devices can enrich our lives. However, as we've noted numerous times over the past year, there are a number of caveats that can also come with them. The glaring issue of course has to do with security, or the lack of it really. And perhaps the absolute lack of ownership certain manufacturers take with it and their products. Research firm Radware once helps underscore the glaring need for better IoT security with some hard proof about what we're dealing with. Employing a "honeypot" approach...

A full-blown Skynet situation might be the thing of science fiction (we hope, anyway), but that doesn't mean bizarre things involving machines can't happen. As proof of this, Verizon teased an entry in its upcoming 2017 Data Breach Digest that describes a recent DDoS attack on an unnamed university involving vending machines, light bulbs, and 5,000 Internet of Things (IoT) devices. As with many DDoS attacks involving IoT devices, this one is the result of system administrators being a little too lax with security on these seemingly benign devices. The university in question dismissed complaints...

Large scale distributed denial of service (DDoS) attacks powered by thousands and sometimes millions of Internet of Things (IoT) devices that have been turned into a massive botnet is something that content delivery networks (CDNs) and service providers must be prepared for in 2017. Lest anyone thinks otherwise, yet another "huge DDoS" assault was reported before the end of this year, this time from Incapsula, which fended off the largest attack to date on its network. With ten days to go before 2016 is in the rear view mirror (along with all of the celebrities it took), Incapsula found itself...

We recently witnessed a new and disturbing trend in cyber security and that is the widespread hacking of Internet connected devices to initiate DDoS attacks on an unprecedented scale. That is the method that made possible the Mirai botnet that targeted security expert Brian Krebs and his security blog with 620 gigabits per second of traffic, which at the time was a record. It is also what's causing a surge in DDoS attacks, as noted by content delivery network (CDN) Akamai. The CDN made its findings known in a recent security report compiled with data gathered from its intelligence platform. In...

On Friday, DNS provider Dyn was walloped by a massive DDoS botnet attack which slowed down or completely sidelined major websites like Amazon, Twitter, and The New York Times. The attack was carried out using improperly configured Internet of Things (IoT) devices that were zombified by Mirai malware. In this particular case, however, the majority of the IoT devices used in the botnet were webcams made by China-based XiongMai Technologies. "It’s remarkable that virtually an entire company’s product line has just been turned into a botnet that is now attacking the United States," said Flashpoint...

So here we go again, another "massive and sustained Internet attack" made possible by a large collection of hacked Internet of Things (IoT) devices, things such as CCTV video cameras, digital video records, all sorts of smart home gadgets with a connection to the Internet, KrebsOnSecurity has determined. This is not the first time it has happened and it won't be the last. The recent attack, an apparent retaliation by WikiLeak supporters after the Obama administration allegedly used its influence to push the Ecuadorian government to cut off Internet access to whistleblower Julian Assange, focused...

This past week has been rife with controversial news related to the U.S. election. Of course, there is always an inordinate amount of news during an election cycle, but this week in particular began with some big stories. First, the U.S. officially accused Russia for the infamous DNC hack that outed the Hillary Clinton campaign's manipulation of the democratic primary. That was followed by WikiLeaks tweeting out an array of cryptic hashes in preparation for its latest data dump, and later the Ecuadorian government admitting it cut WikiLeaks’ founder, Julian Assange’s, access to the Internet in...

If the internet was incredibly slow for you this morning when browsing certain websites, or if you were having trouble posting your “wakeup” tweet to Twitter, we now know the root cause. A massive distributed denial of service (DDoS) attack was carried out against Dyn, which provides DNS service to a number of big name sites including Amazon, Twitter, reddit, Spotify, The New York Times, and Airbnb (among others). The outages seemed to mainly be concentrated around the northeastern United States, with another “hot pocket” of activity centered in Texas. Dyn posted a note to its website earlier this...

Well, this isn't good. The source code for the botnet that took KrebsOnSecurity down by tapping into an unprecedented number of Internet of Things (IoT) devices has been released to the public. It's availability virtually ensures that distributed denial of service (DDoS) attacks equal in size or even larger will follow, creating financial headaches and service disruptions for companies both big and small. Brian Krebs, a renowned security expert and author of the aforementioned blog, recently found his website the target of one of the largest DDoS attacks in history. The massive attack brought in...

If you thought that the massive DDoS attack earlier this month on Brian Krebs’ security blog was record-breaking, take a look at what just happened to France-based hosting provider OVH. OVH was the victim of a wide-scale DDoS attack that was carried via network of over 152,000 IoT devices. According to OVH founder and CTO Octave Klaba, the DDoS attack reached nearly 1 Tbps at its peak. Of those IoT devices participating in the DDoS attack, they were primarily comprised of CCTV cameras and DVRs. Many of these types devices' network settings are improperly configured, which leaves them ripe...

The web is becoming the wild, wild west all over again it seems. You could argue the Internet's always been a potentially dangerous place, but with the proliferation of smart devices becoming increasingly commonplace, cybercriminals now have more points of entry into home networks than ever before. Smart home automation gadgets collectively comprise much of what's referred to as the Internet of Things (IoT), and just like your PC, they can be silently hijacked and enlisted into a botnet, a malicious network of systems under the control of a foreign party. Individually, all these smart lighting,...

Today the bad guys have won. Not the war, mind you, but a skirmish with renowned security journalist Brian Krebs, author of The New York Times bestseller "Spam Nation," a former writer for the The Washington Post, and owner of KrebsOnSecurity, a popular security blog that's no longer live after cloud service provider Akamai gave Krebs just 2 hours to pack his things and leave. Of course, there's more to the story than that. Akamai isn't some evil company secretly working for the bad guys (we hope not, anyway). But it was providing free service to Krebs for his blog. You get what you pay for. In...

Researchers from the Negev Cyber-Security Research Center at Ben-Gurion University recently released a terrifying piece of news. It explains that if a malicious entity decided to craft malware that infected only a few thousand mobile phones, it would be possible to cripple an entire 911 system. That means legitimate calls couldn't make it through, and staffers manning the lines would be inundated with fake calls. The research published last week reveals that in most states, if as few as 6,000 mobile phones were infected with malware that serves no other purpose but...
