Mobile is the new frontier for malicious bots

Distil Networks analyzed over 100 million mobile devices on its networks. The findings suggest that sophisticated cybercriminals and bot operators now implement a new technique—leveraging mobile devices – to avoid detection and execute a number of nefarious acts. At this time, 5.8 percent of all mobile devices across six major cellular networks are used in such automated attacks and represent eight percent of all bad bot traffic.

This bad bot traffic is purposefully deployed against any business with a web presence to carry out acts that include web scraping, brute force attacks, competitive data mining, online fraud, account hijacking, data theft, spam and digital ad fraud.

Uncovered by the Distil Research Lab, the data reveals a new method by which perpetrators connect through cellular gateways to target a large variety of websites and apps simultaneously. Cellular gateways handle a huge volume of requests per minute, many of which are legitimate, making it difficult to identify and block criminal ones.

Within some cellular carriers, a single IP address can cater to more than 4,000 devices per day, making cellular traffic an ideal location for bots to remain undetectable. As mobile devices move through different gateways, (based on device owners changing location throughout the day,) bots effectively change identities to make detection even more difficult.

Mobile bots by the numbers:

  • Sample size: Over 100 million devices
  • Number of mobile carriers researched: Six
  • Percentage of mobile ISP gateways used in bad bot attacks: 44 percent
  • Percentage of total bad bot traffic deriving from mobile devices on cellular networks: 8 percent
  • Percentage of mobile devices making bad bot requests on cellular networks: 5.8 percent
  • Average number of bad bot requests by each device per day: 50.

Mobile is the new frontier for bot operators, as they can perform highly advanced attacks while remaining hidden in plain sight,” said Rami Essaid, chief product and strategy officer at Distil Networks. “Whether inadvertently downloaded through an email attachment, or embedded in a seemingly legitimate app, millions of consumers unknowingly carry malware on their devices that allows cybercriminals to conduct bot attacks, abuse and fraud. We have seen bot operators develop and enhance their techniques throughout the years, but the threat to mobile devices is real and growing, and can have detrimental consequences.

Twitter gets physical – with support for hardware security keys

Twitter has given millions of users a way of making their accounts even harder to hack, with the introduction of support for physical keys.

Most Twitter users protect their accounts in the traditional way: username and password. As with any other internet account, such security is vulnerable to a number of threats including phishing or a user unwisely choosing the same password that they use elsewhere on the internet.

This is the primary reason that so many Twitter accounts have been compromised by hackers over the years.

High profile victims have included FC Barcelona, CNN, Burger King, Google CEO Sundar Pichai, Wikipedia’s Jimmy Wales, and Mark Zuckerberg.

One of the most notorious hijackings of a Twitter account occurred in 2013, when the Syrian Electronic Army managed to gain control of Associated Press’s Twitter account and posted a message saying that there had been an explosion at the White House and Barack Obama had been injured.

That bogus report knocked 61 billion dollars (briefly) off the Dow Jones Index.

If you’re sensible you have taken better steps than just a password to protect your Twitter account, and enabled two-step verification in the form of “Login Verification”.That adds an extra hurdle to the login process by asking for a code generated by a third-party app such as Google Authenticator and Authy to be be entered.

For most people, this level of protection is probably enough.

But what if you want to go even further, and wish to ensure an even high level of physical security to your Twitter account?

If that’s you then you’ll be interested to read news inside a blog post detailing Twitter’s latest steps to combat spam and abuse on the site.

Twitter has revealed that you can now use a physical USB security key which supports the universal two-factor (U2F) standard when signing in for login verification.

The small keyfobs require the logging-in user to physically press a button to confirm the identity, and because it will only work on the real Twitter website it provides a high level of protection against phishing sites.

Other websites which support FIDO U2F hardware keys – which are the same size and shape as a typical USB thumb drive – include Google, Facebook, Dropbox, GitHub, and SalesForce.

Cisco plugs critical flaws in many switches, security appliances.

Cisco has released security updates to address a bucketload of vulnerabilities affecting multiple products, including 24 critical and high-severity flaws found in many of its switches, next generation firewalls and security appliances.

Cisco switches critical flaws

Those vulnerabilities are present in the Cisco NX-OS Software, which enables network automation and programmatical provisioning and configuration of the devices via APIs, and Cisco FXOS (Firepower eXtensible Operating System).

“Successful exploitation of the vulnerabilities could allow an attacker to gain unauthorized access to an affected device, gain elevated privileges for an affected device, execute arbitrary code, execute arbitrary commands, gain access to sensitive information, or cause a denial of service (DoS) condition on an affected device,” the company explained.

They can be exploited via specially crafted packets (HTTP or HTTPS, Cisco Fabric Services, SNMP, IGMP) and messages (Cisco Discovery Protocol and BGP update messages).

Twelve of the vulnerabilities affect both Cisco FXOS Software and Cisco NX-OS Software and the remaining vulnerabilities affect only Cisco NX-OS Software. None of the vulnerabilities affect Cisco IOS Software or Cisco IOS XE Software.

There are no workarounds for the vulnerabilities, so administrators should implement the offered updates.

The Key IoT Security Questions You Need To Ask

Microsoft IoT Security

An Internet of Things (IoT) solution offers a multitude of business benefits from decreased operational costs to new revenue streams. But it also comes with a host of security considerations, including an ever-changing array of regulatory compliance requirements, demanding expert navigation and acute attention to detail.

Below I’ve listed some of the critical questions to ask when deploying a secure IoT solution. To learn more about IoT security, be sure to register for the IoT in Action event in San Francisco on February 13.

How secure are your things?

For starters, the actual devices must be secure. In the next few years, a new wave of innovation will drive down costs and inundate the market with internet-connected devices in every price range, from electronic toys to manufacturing sensors. In anticipation of this, my Microsoft colleagues have identified The seven properties of highly secure devices. I have listed out each of these properties below, along with the fundamental questions you must ask:

  1. The hardware-based root of trust: Does each device have a unique identity that is inseparable from the hardware?
  2. Small trusted computing base: Is most of the device’s software outside its trusted computing base?
  3. Defense in depth: Does your device software have multiple layers of protection built-in?
  4. Compartmentalization: Are you using hardware-enforced barriers to stop failures from propagating to other components?
  5. Certificates-based authentication: Do your devices use certificates (vs. passwords)?
  6. Renewable security: Can the device’s software be updated automatically to a more secure state?
  7. Failure reporting: Do you have a solution in place to report software failures to the manufacturer?

How secure are your connections? 

More to the point, when you’ve got a bunch of devices talking to each other over the internet, how will you safeguard data confidentiality and integrity? When choosing an IoT monitoring and connection solution, make sure that it is using industry-proven data encryption. Solutions like the Azure IoT Suite secure the internet connection between the IoT device and IoT hub using the Transport Layer Security (TLS) standard.

Another question to ask is how you will prevent unsolicited inbound connections from wreaking havoc on your devices? Make sure that only devices are allowed to initiate connections and not the IoT hub. And speaking of the IoT hub: make sure that the one you’re using has the capability of maintaining a per-device queue – meaning that it can store messages for devices and wait for the devices to connect. For more on this topic, be sure to read IoT security from the ground up.

How secure is your cloud solution?

Is your cloud provider following rigorous security best practices? When choosing a cloud provider, make sure you pay careful attention to how they are handling the following areas.

  1. Network traffic segregation: Is IoT traffic segregated from other network traffic using an IoT gateway or other means?
  2. Monitoring: How is network traffic being monitored? How will you know if any credentials are compromised or if unmanaged devices are accessing your cloud services?
  3. Security controls: How well do you know your cloud provider’s SLA (service-level agreement)? Which security controls are being maintained by your provider and which will you need to address internally?
  4. Encryption and security key management: Does your IoT solution allow you to define access control policies for each security key? Is data in the cloud encrypted?

ATM ‘jackpotting’ hacks reach the US

For some ATM thieves, swiping card data involves too much patience — they’d rather just take the money and run. The US Secret Service has warned ATM makers Diebold Nixdorf and NCR that "jackpotting" hacks, where crooks force machine to cough up large sums of cash, have reached the US after years of creating problems in Asia, Europe and Mexico. The attacks have focused largely on Diebold’s front-loading Opteva ATMs in stand-alone locations, such as retail stores and drive-thrus, and have relied on an combination of malware and hardware to pull off heists.

In previous attacks, the thieves disguised themselves as technicians to avoid drawing attention. After that, they hooked up a laptop with a mirror image of the ATM’s operating system and malware (Diebold also mentioned replacing the hard drive outright). Security researcher Brian Krebs understands American ATMs have been hit with Ploutus.D, a variant of "jackpotting" malware that first launched in 2013. The mirror image needs to be paired with the ATM to work, but that’s not as difficult as you might think — the intruders used endoscopes to find and press the necessary reset button inside the machine. Once done, they attached keyboards and used activation codes to clean out ATMs within a matter of minutes.

NCR hasn’t been explicitly targeted in these attacks, but it warned that this was an "industry-wide issue" and urged caution from companies using its ATMs.

It’s definitely possible to thwart attacks like this. The Secret Service warned that ATMs still using Windows XP were particularly easy targets, and that updating to Windows 7 (let alone Windows 10) would protect against these specific attacks. Diebold also recommended updating to newer firmware and using the most secure configurations possible. And both organizations recommended physical security changes, such as using rear-loading ATMs, locking down physical access and closely watching for suspicious activity like opening the machine’s top.

The catch, of course, is that ATM operators either haven’t been diligent or may have a hard time justifying the updates. It’s telling that victim machines have been running XP, a 16-year-old platform whose official support ended in 2014 — the odds aren’t high that companies will keep their ATMs up to date, let alone replace them with more secure models or institute advanced defenses. You may not see a widespread attempt to combat jackpotting in the US until the problem becomes too large to ignore.

Google X Is Launching a Cybersecurity Company Called Chronicle

Google’s parent company Alphabet today announced the launch of Chronicle, a new cybersecurity company that aims to give companies a better chance at detecting and fighting off hackers. "Chronicle is graduating out of Alphabet’s X moonshot group and is now a standalone company under the Alphabet umbrella, just like Google," TechCrunch reports. From the report: Stephen Gillett, who joined X from Google Ventures and was previously the COO of Symantec, will be the new company’s CEO. To get started, Chronicle will offer two services: a security intelligence and analytics platform for enterprises, and VirusTotal, the online malware and virus scanner that Google acquired in 2012. Gillett writes that the general idea behind Chronicle is to eliminate a company’s security blind spots and allow businesses to get a better picture of their security posture. "We want to 10x the speed and impact of security teams’ work by making it much easier, faster and more cost-effective for them to capture and analyze security signals that have previously been too difficult and expensive to find," writes Gillett. "We are building our intelligence and analytics platform to solve this problem." What exactly this new platform will look like remains to be seen, though. Gillett notes that it will run on Alphabet’s infrastructure and use machine learning and advanced search capabilities to help businesses analyze their security data. Chronicle also says that it will offer its services in the cloud so that they can "grow with an organization’s needs and don’t add yet another piece of security software to implement and manage."
