SHARED INTEL: Threat actors add a human touch to boost effectiveness of automated attacks

By Byron V. Acohido

Trends in fashion and entertainment come and go. The same holds true for the cyber underground.

For a long while now, criminal hackers have relied on leveraging low-cost botnet services to blast out cyber attacks as far and wide as they could, indiscriminately. Over the past 18 months or so, a fresh trend has come into vogue. It essentially involves applying hands-on human cleverness to the task of extracting highest value from assets gained in the automated sweeps.

British antimalware and network security vendor Sophos refers to this new tactic as “automated, active attacks.” Sophos Senior Security Advisor John Shier broke it down for me. We met at Black Hat 2019. For a full drill down, give a listen to the accompanying podcast. Here are the key takeaways:

Human touch

It has long been common practice to use botnets to blast out wave after wave of e-mails carrying tainted PDFs or Word docs, or a web link pointing to a booby-trapped page – and seeing who would bite. Lately, progressive criminal rings are taking a page out of the playbook of nation-state sponsored APT strikes — by adding more human nuances to their attacks.

“They may discover their targets through some sort of automated technique, which gets them a toehold into the company, or they might just simply go to Shodan (search engine) to discover open, available RDP hosts,” Shier told me. “Once they’re in the front door, now the humans get involved.”

Specialists get assigned to poke around, locate key servers and find stealthy paths to send in more malware. They’ll take more manual steps to encrypt servers, exfiltrate data – or do both.

“Cyber criminals are getting into the environment, elevating privileges as much as they can and moving laterally to other segments of the network,” Shier says. “And then, instead of encrypting one or two or ten machines, they’ll encrypt everything.”

The wave of catastrophic ransomware attacks that wrought tens of millions in recovery costs for the cities of Baltimore and Atlanta and prompted numerous small cities to pay six figure ransoms for decryption keys is a prime example of this, Shier says. …more

MY TAKE: ‘Perimeter-less’ computing requires cyber defenses to extend deeper, further forward

By Byron V. Acohido

Threat actors are opportunistic, well-funded, highly-motivated and endlessly clever.

Therefore cybersecurity innovations must take hold both deeper inside and at the leading edges of modern business networks.

Most of the promising new technologies I’ve had the chance to preview this year validate this notion. The best and brightest security innovators continue to roll out solutions designed to stop threat actors very deep – as deep as in CPU memory — or at the cutting edge, think cloud services, IoT and DevOps exposures.

Juniper Networks, the Sunnyvale, CA – based supplier of networking equipment, I discovered, is actually doing both. I came to this conclusion after meeting with Oliver Schuermann, Juniper’s senior director of enterprise marketing.

We met at Black Hat 2019 and Schuermann walked me through how Juniper’s security play pivots off the evolving infrastructure of a typical corporate network. For a full drill down, please give a listen to the accompanying podcast. Here are the key takeaways:

Deeper sharing

Wider threat intelligence sharing continues to advance apace. I was in the audience at Stanford in 2015 when President Obama signed an executive order urging the corporate sector to accelerate the sharing of threat feeds among themselves and with the federal government.

Since then, a number of threat intel sharing consortiums have either formed or expanded their activities. One recent example is how five midwestern universities – Indiana, Northwestern, Purdue, Rutgers and Nebraska – partnered to create a joint security operation center to gather, analyze and act on threat feeds.

Juniper gathers threat feeds via a security framework, called SecIntl, that runs off servers tied together by Juniper equipment deployed globally in corporate networks. …more

NEW TECH: The march begins to make mobile app security more robust than legacy PC security

By Byron V. Acohido

Is mobile technology on a course to become more secure than traditional computing?

Seven or eight years ago, that was a far-fetched notion. Today, the answer to that question is, “Yes, it must, and soon.”

I’ve been writing about organizations struggling to solve the productivity vs. security dilemma that’s part and parcel of the BYOD craze for some time now. I can recall President Obama issuing BlackBerry phones and ordering his administration to copy his personal practice of using only hardened mobile devices. Yet, many of the government-issued BlackBerry phones got used sporadically, as staffers reverted to their personally owned iPhones and Androids.

What has happened over the past couple of years is that mobile computing has become the cornerstone of our work and personal lives. Meanwhile, threat actors, as you might expect, are increasingly probing for, regularly discovering and enthusiastically exploiting mobile security flaws.

The good news is that cybersecurity vendors continue to innovate, as they have all along. And they appear to be closing in on fresh approaches that should translate into solutions for the longer haul. It is early still, but it looks like we may not have to carry two smartphones, after all, a locked-down company phone, as well as our favorite personal device.

I had the chance to discuss this with Jonas Gyllensvaan and Brian Egenrieder, Chief Executive Officer and Chief Revenue Officer, respectively, of mobile security vendor SyncDog. We spoke at Black Hat 2019. For a full drill down, give a listen to the accompanying podcast. Here are key takeaways:

Securing provisioned devices

From the very start of the smartphone era, employees demonstrated that they did not mind paying for the latest, coolest device and use it for both home and work tasks. By 2011 or so, it was clear the BYOD trend was unstoppable, and companies began to impose much tighter security constraints.

Along came MDMs (mobile device management) services to handle the inventorying and provisioning of these new endpoints. MDMs gave companies the ability to micromanage company-issued devices, adding password protection and remote wiping capabilities. A security staffer could remotely “brick” a company device gone temporarily missing, even if it had just slipped under a couch cushion. The employer could even block access to apps stores, disable phone cameras or use the device’s GPS function to monitor where an employee spends work and personal hours.

Employee’s bristled – and companies responded by exerting even more granular control by embedding EMM (enterprise mobility management,) MAM (mobile application management) and UEM (unified endpoint management) systems on provisioned devices. …more

MY TAKE: Local government can do more to repel ransomware, dilute disinformation campaigns

By Byron V. Acohido

Local government agencies remain acutely exposed to being hacked. That’s long been true. However, at this moment in history, two particularly worrisome types of cyber attacks are cycling up and hitting local government entities hard: ransomware sieges and election tampering.

I had a deep discussion about this with Todd Weller, chief strategy officer at Bandura Cyber. We spoke at Black Hat USA 2019. Bandura Cyber is a 6-year-old supplier of threat intelligence gateway technologies. It helps organizations of all sizes but has a solution that is well suited to enable more resource constrained SMBs, tap into the myriad threat feeds being collected by a wide variety of entities and extract actionable intelligence.

Weller observed that local governments are under pressure to more proactively detect and deter threat actors, which means they must figure out how to redirect a bigger chunk of limited resources toward mitigating cyber threats. Current attack trends add urgency, and catching up on doing basic security best practices isn’t enough. For a drill down on my interview with Weller, give a listen to the accompanying podcast. Here are key takeaways:

Ransomware run

We’ve recently learned just how easy it is for ransomware purveyors to either extract huge extortion payments from local agencies, or worse, cause tens of millions of dollars of damage.

Baltimore city officials declined to pay $76,000 for a ransomware decryption key – and the city ended up absorbing an estimated $18 million in recovery costs. Atlanta refused to pay a $51,000 ransom, and ate $17 million in damage.

Meanwhile, officials from Riviera Beach, Fla., population 35,000, saw fit to cough up a $600,000 payment, and Lake City, Fla., population 12,046, paid $460,000, respectively, for ransomware decryption keys. In each case, after weeks of having city services disrupted, and facing pressure from constituents, city leaders viewed paying a six-figure ransom as the least painful, quickest resolution. …more

MY TAKE: What everyone should know about the promise and pitfalls of the Internet of Things

By Byron V. Acohido

The city of Portland, Ore. has set out to fully leverage the Internet of Things and emerge as a model “smart” city.

Portland recently shelled out $1 million to launch its Traffic Sensor Safety Project, which tracks cyclists as they traverse the Rose City’s innumerable bike paths. That’s just step one of a grand plan to closely study – and proactively manage – traffic behaviors of cyclists, vehicles, pedestrians and joggers. This is all in pursuit of the high-minded goal of eliminating all accidents that result in death or serious injury.

Portland is shooting high, and it is by no means alone. Companies in utilities, transportation and manufacturing sectors are moving forward with the …more

SHARED INTEL: Mobile apps are riddled with security flaws, many of which go unremediated

By Byron V. Acohido

The convergence of DevOps and SecOps is steadily gaining traction in the global marketplace. Some fresh evidence of this encouraging trend comes to us by way of shared intelligence from WhiteHat Security.

Organizations that are all-in leveraging microservices to speed-up application development, on the DevOps side of the house, have begun acknowledging the importance of incorporating SecOps along the way. The most forward-thinking among them are increasingly checking for vulnerabilities in new apps – and finding them, big time.

That’s one of the key revelations in the 2019 WhiteHat Application Security Statistics Report, which I’d place in the category of reports that bear close scrutiny because it is based on the actual in-the-field experiences of WhiteHat’s global customer base. Also, WhiteHat has been generating this report annually since 2006.

Based on 17 million application security scans carried out in 2018, WhiteHat found a 20% increase in vulnerabilities found in the applications that organizations tested for security flaws.

What’s more, based on WhiteHat’s partner, NowSecure’s insight, some 70% of mobile apps were found to leak sensitive data.

The fact that more companies are participating in the hunt for security flaws in new apps is a good thing. However, WhiteHat also found many app vulnerabilities are, today, going unaddressed. Remediation rates actually fell in 2018, as compared to 2017. At the moment, the effort required to secure existing and new apps appears to be overwhelming already short-staffed security teams.

The Dawn of DevSecOps

This field report tells us that, yes, SecOps is gaining traction, with more and more security teams beginning to contribute to the delivery of secure apps. However, many security teams lack the skills, and/or have not yet won corporate backing to bring in the engineering support needed to mitigate the vulnerabilities.

These applications flaws were always there, mind you – WhiteHat found that more than one-third of all application security risks are inherited rather than written – but now they are being flushed out as DevOps and SecOps merge into DevSecOps.

The more progressive security teams are, indeed, tackling remediation. For those teams, the benefits associated with paying a bit of attention to security, up front, have sunk in. Not only can they take pride in contributing to a better experience for end users, they’re also reducing the headaches that go along with having to patch vulnerabilities that turn up, post production. …more

MY TAKE: Here’s how ‘bulletproof proxies’ help criminals put compromised IoT devices to work

By Byron V. Acohido

Between Q1 2019 and Q2 2019, malicious communications emanating from residential IP addresses in the U.S. – namely smart refrigerators, garage doors, home routers and the like – nearly quadrupled for the retail and financial services sectors.

To put it plainly, this represented a spike in cyber attacks bouncing through ordinary Internet-connected devices humming away in homes across America. These attacks were carried out by cyber criminals leveraging an insidious new attack tool: bulletproof proxies.

What were they up to? IoT devices are proving to be an integral element for cyber criminals to launch automated attack campaigns to manipulate social media likes, create fake accounts, take over existing accounts, execute credential stuffing, content scraping, click fraud and carry out other cyber villainy.

This stunning intel comes in a study from Cequence Security, a Sunnyvale, CA-based vendor focused on helping companies defend against such attacks. These findings have huge implications, not just highlighting what a huge drain botnets have become to our Internet-centric economy, but also underscoring how botnets have become a disruptive force in political discourse, globally.

I had a deep discussion about this with Cequence’s Will Glazier, head of research, and Matt Keil, director of product marketing, at Black Hat USA 2019. For a full drill down, give a listen to the accompanying podcast. My big takeaways:

Bulletproof weaponry

Back in 2007, a noted fellow journalist, Brian Krebs, exposed how the Russian Business Network had pioneered something called “bulletproof hosting.” RBN provided web hosting services to one-and-all, and then looked the other way as spammers, fraudsters and even child pornography distributors did their thing, operating their botnets with impunity.

Just the other day, Krebs broke another story about what he’s calling “bulletproof residential VPN services.” And Cequence has done deep analysis on “bulletproof proxies” — the latest, greatest iteration of bulletproof hosting. Instead of building out and hosting a server farm that can be isolated and potentially shut down by law enforcement, bulletproof proxy providers today assemble millions of globally distributed IP addresses and make those available to one-and-all.

Crucially, the availability of an endless supply of IP addresses reinforces the viability of botnets. (A bot is a computing nodule, and a botnet is a network of nodules under control of the botnet master.) The fact that botnet nodules today increasingly spin out of residential IP addresses is significant for two reasons: …more
