Notorious ‘Hijack Factory’ Shunned from Web

Score one for the good guys: Bitcanal, a Portuguese Web hosting firm long accused of helping spammers hijack large swaths of dormant Internet address space over the years, was summarily kicked off the Internet this week after a half-dozen of the company’s bandwidth providers chose to sever ties with the company.

Dell Lost Control of Key Customer Support Domain for a Month in 2017

A Web site set up by PC maker Dell Inc. to help customers recover from malicious software and other computer maladies may have been hijacked for a few weeks this summer by people who specialize in deploying said malware, KrebsOnSecurity has learned.

There is a program installed on virtually all Dell computers called “Dell Backup and Recovery Application.” It’s designed to help customers restore their data and computers to their pristine, factory default state should a problem occur with the device. That backup and recovery program periodically checks a rather catchy domain name — DellBackupandRecoveryCloudStorage.com — which until recently was central to PC maker Dell’s customer data backup, recovery and cloud storage solutions.

Sometime this summer, DellBackupandRecoveryCloudStorage.com was suddenly snatched away from a longtime Dell contractor for a month and exposed to some questionable content. More worryingly, there are signs the domain may have been pushing malware before Dell’s contractor regained control over it.

Reaper: Calm Before the IoT Security Storm?

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.

DDoS, IoT Top Cybersecurity Priorities for 45th President

Addressing distributed denial-of-service (DDoS) attacks designed to knock Web services offline and security concerns introduced by the so-called “Internet of Things” (IoT) should be top cybersecurity priorities for the 45th President of the United States, according to a newly released blue-ribbon report commissioned by President Obama.

Chinese IoT Firm Siphoned Text Messages, Call Records

A Chinese technology firm has been siphoning text messages and call records from cheap Android-based mobile smart phones and secretly sending the data to servers in China, researchers revealed this week. The revelations came the same day the White House and the U.S. Department of Homeland Security issued sweeping guidelines aimed at building security into Internet-connected devices, and just hours before a key congressional panel sought recommendations from industry in regulating basic security standards for so-called “Internet of Things” devices.

Did the Mirai Botnet Really Take Liberia Offline?

KrebsOnSecurity received many a missive over the past 24 hours from readers who wanted to know why I’d not written about widespread media reports that Mirai — a malware strain made from hacked “Internet of Things” (IoT) devices such as poorly secured routers and IP cameras — was used to knock the entire country of Liberia offline. The trouble is, as far as I can tell no such nationwide outage actually occurred.

Hackforums Shutters Booter Service Bazaar

Perhaps the most bustling marketplace on the Internet where people can compare and purchase so-called “booter” and “stresser” subscriptions — attack-for-hire services designed to knock Web sites offline — announced last week that it has permanently banned the sale and advertising of these services.

Are the Days of “Booter” Services Numbered?

It may soon become easier for Internet service providers to anticipate and block certain types of online assaults launched by Web-based attack-for-hire services known as “booter” or “stresser” services, new research released today suggests.

IoT Device Maker Vows Product Recall, Legal Action Against Western Accusers

A Chinese electronics firm pegged by experts as responsible for making many of the components leveraged in last week’s massive attack that disrupted Twitter and dozens of popular Web sites has vowed to recall some of its vulnerable products, even as it threatened legal action against this publication and others for allegedly defaming the company’s brand.

Hacked Cameras, DVRs Powered Today’s Massive Internet Outage

A massive and sustained Internet attack that has caused outages and network congestion today for a large number of Web sites was launched with the help of hacked “Internet of Things” (IoT) devices, such as CCTV video cameras and digital video recorders, new data suggests.
