MY TAKE: Android users beware: Google says ‘potentially harmful apps’ on the rise

By Byron V. Acohido

Even if your company issues you a locked-down smartphone, embracing best security practices remains vital
Our smartphones. Where would we be without them?

If you’re anything like me, making a phone call is the fifth or sixth reason to reach for your Android or iPhone. Whichever OS you favor, a good portion of the key components that make up your digital life — email, texting, social media, shopping, banking, hobbies, and work duties — now route through these indispensable contraptions much of the time.

Cybercriminals know this, of course, and for some time now they have been relentlessly seeking out and exploiting the fresh attack vectors spinning out of our smartphone obsession.

Don’t look now, but evidence is mounting that the mobile threats landscape is on the threshold of getting a lot more dicey.

This is because mobile services and smartphone functionalities are rapidly expanding, and, as you might expect, cyberattacks targeting mobile devices and services are also rising sharply. Here are a few key developments everyone should know about.

Malware deliveries

Upon reviewing Android usage data for all of 2018, Google identified a rise in the number of “potentially harmful apps” that were preinstalled or delivered through over-the-air updates. Threat actors have figured out how to insinuate themselves into the processes that preinstall apps on new phones and push out OS updates.

Why did they go there? Instead of having to trick users one by one, fraudsters only have to deceive the device manufacturer, or some other party involved in the supply chain, and thereby get their malicious code delivered far and wide.

In a related development, OneSpan, a Chicago-based supplier of authentication technology to 2,000 banks worldwide, reports seeing a rise in cyber attacks targeting mobile banking patrons. “Popular forms of mobile attacks, at this point in time, include screen scrapers and screen capture mechanisms, as well as the installation of rogue keyboards,” said OneSpan security evangelist Will LaSala. …more

BEST PRACTICES: The case for ‘adaptive MFA’ in our perimeter-less digital environment

By Byron V. Acohido

One of the catch phrases I overheard at RSA 2019 that jumped out at me was this: “The internet is the new corporate network.”

Think about how far we’ve come since 1999, when the Y2K scare alarmed many, until today, with hybrid cloud networks the norm. There’s no question the benefits of accelerating digital transformation are astounding.

Yet the flip side is that legacy security approaches never envisioned perimeter-less computing. The result, not surprisingly, has been a demonstrative lag in transitioning to security systems that strike the right balance between protection and productivity.

Take authentication, for example. Threat actors are taking great advantage of the lag in upgrading authentication. The good news is that innovation to close the gap is taking place. Tel Aviv-based security vendor Silverfort is playing in this space, and has found good success pioneering a new approach for securing authentication in the perimeterless world.

Founded in 2016 by cryptography experts from the Israeli Intelligence Corps’ elite 8200 cyber unit, Silverfort is backed by leading investors in cybersecurity technologies.

I had the chance to catch up with Dana Tamir, Silverfort’s vice president of market strategy, at RSA 2019. For a full drill down of the interview, please listen to the accompanying podcast. Here are the key takeaways:

Eroding effectiveness

Compromised credentials continue to be the cause of many of today’s data breaches. The use of multi-factor authentication, or MFA, can help protect credentials, but even those solutions have lost much of their effectiveness. The problem is that most MFA solutions are designed for specific systems, rather than today’s more dynamic environments. Traditional MFA may have hit its limitations due to dissolving perimeters.

In the past, Tamir explained, you had a solid perimeter around your network, with one entry point and you added the MFA to that single entry for the extra layer of protection. But that single-entry perimeter doesn’t exist today. We don’t even have a real perimeter anymore. …more

GUEST ESSAY: How stealth, persistence allowed Wipro attacker to plunder supply chain

By Chris Gerritz

The recent network breach of Wipro, a prominent outsourcing company based in India, serves as a stunning reminder that digital transformation cuts two ways.

Our rising dependence on business systems that leverage cloud services and the gig economy to accomplish high-velocity innovation has led to a rise in productivity. However, the flip side is that we’ve also created fresh attack vectors at a rapid rate – exposures that are not being adequately addressed.

We now know, thanks to reporting from cybersecurity blogger Brian Krebs, that the Wipro hack was a multi-month intrusion and likely the work of a nation-state backed threat actor. What’s more, the attackers reportedly were able to use Wipro as a jumping off point to infiltrate the networks of at least a dozen of Wipro’s customers.

Wipro issued a media statement, via its Economic Times division, acknowledging “potentially abnormal activity in a few employee accounts on our network due to an advanced phishing campaign . . . Upon learning of the incident, we promptly began an investigation, identified the affected users and took remedial steps to contain and mitigate any potential impact.”

Wipro did not provide many additional details. However, one has to wonder whether, beyond its customers, …more

Q&A: Here’s why Android users must remain vigilant about malicious apps, more so than ever

By Byron V. Acohido

Android users – and I’m one – are well-advised to be constantly vigilant about the types of cyberthreats directed, at any given time, at the world’s most popular mobile device operating system.

Attacks won’t relent anytime soon, and awareness will help you avoid becoming a victim. It’s well worth it to stay abreast of news about defensive actions Google is forced to take to protect Android users. Just recently, for instance, the search giant removed 50 malicious apps, installed 30 million times, from the official Google Play Store, including fitness, photo-editing, and gaming apps.

And earlier this year, three popular “selfie beauty apps”– Pro Selfie Beauty Camera, Selfie Beauty Camera Pro and Pretty Beauty Camera 2019 – accessible in Google Play Store were revealed to actually be tools to spread adware and spyware. Each app had at least 500,000 installs, with Pretty Beauty Camera 2019 logging over 1 million installs, mainly by Android users in India.

Instructive details about both of these malicious campaigns come from malware analysts working on apklab.io, which officially launched in February. Apklab.io is Avast’s mobile threat intelligence platform designed to share intelligence gathered by analyzing samples collected from 145 million Android mobile devices in use worldwide.

I had the chance to sit down with Nikolaos Chrysaidos (pictured), head of mobile threat intelligence and security at Avast, to drill down on the wider context of the helpful findings apklabl.io has begun delivering. Here are excerpts of our discussion, edited for clarity and length:

Acohido: What was distinctive about the 50 malicious Android apps your analysts recently discovered?

Chrysaidos: The installations ranged from 5,000 to 5 million installs, and included adware that persistently displayed full screen ads, and in some cases, tried to convince the user to install further apps. The adware applications were linked together by the use of third-party Android libraries, which bypass the background service restrictions present in newer Android versions.

The bypassing itself is not explicitly forbidden on Play Store. However, our analysts were able to detect it because apps using these libraries waste the user’s battery and make the device slower. In this instance, the libraries kept displaying more and more ads, which does violate the Google Play Store rules. …more

NEW TECH: DataLocker extends products, services to encrypt data on portable storage devices

By Byron V. Acohido

No matter how reliant we ultimately become on cloud storage and streaming media, it’s hard to image consumers ever fully abandoning removable storage devices.

There’s just something about putting your own two hands on a physical device, whether it’s magnetic tape, or a floppy disk, or a CD. Today, it’s more likely to be an external drive, a thumb drive or a flash memory card.

Ever thought about encrypting the data held on a portable storage device? Jay Kim, co-founder and CEO DataLocker, did.

Launched as a one-man operation in 2007, DataLocker has grown into a leading manufacturer of encrypted external drives, thumb drives, flash drives and self-encrypting, recordable CDs and DVDs.

DataLocker today has 40 employees and last year moved into a larger facility in Overland Park, Kansas, with room to grow. I had the chance at RSA 2019 to visit with Shauna Park, channel manager at DataLocker, to discuss what’s new in the encrypted portable drive space. For a full drill down please listen to the accompanying podcast. Key takeaways:

Protected backup

Even with increased adoption of cloud computing, external storage devices, like USB thumb drives and external hard drives, still have a major role in organizations of all sizes. These drives still serve a purpose, such as transporting data from one computer to another, accessing presentations outside of the office, or as an additional backup solution. …more

NEW TECH: SlashNext dynamically inspects web page contents to detect latest phishing attacks

By Byron V. Acohido

Humans are fallible. Cyber criminals get this.

Human fallibility is the reason social engineering has proven to be so effective – and why phishing persists. Consider these metrics from messaging security firm Proofpoint:

•Email-based corporate credential phishing attacks quadrupled in Q3 2018 vs. the previous quarter.

•Web-based social engineering attacks jumped 233% vs. the previous quarter.

•99% of the most highly targeted email addresses in the quarter didn’t rank as such in the previous report, suggesting that attackers are constantly shifting targets.

What’s more, a study by antivirus vendor Webroot informs that more than 46,000 new phishing sites go live each day, with most disappearing in a few hours. And a recent survey conducted by SlashNext, a Pleasanton, CA-based supplier of advanced antiphishing systems, revealed that 95% of IT professionals underestimate phishing attack risks. This holds true even though nearly half the respondents reported their organizations experience 50 or more phishing attacks per month, with 14% experiencing 500 phishing attacks per month.

It’s not as if companies and cybersecurity vendors have been sitting on their hands. Vast resources have been directed at filtering emails – the traditional delivery vehicle for phishing campaigns – and at identifying and blacklisting webpages that serve as landing pages and payload delivery venues.

So quite naturally, cyber criminals have shifted their attack strategies. They are pursuing fresh vectors and honing innovative payload delivery tactics. The bad guys are taking full advantage of the fact that many companies continue to rely on legacy defenses geared to stop tactics elite phishing rings are no longer using.

I recently had an eye-opening discussion about this with Jan Liband, SlashNext’s chief marketing officer. Here are the key takeaways from that interview:

Unguarded vectors

By now, most mid-sized and large enterprises have a secure email gateway that’s highly effective at filtering out 80%-95% of phishing emails. So phishers have moved on to comparatively unguarded vectors: social media channels, SMS (text), ads, pop-ups, chat apps, IM, malvertising and rogue browser extensions, Liband told me.

Platforms like Facebook, Twitter and Instagram are wide open for intelligence gathering. With knowledge of our friends, families and preferences, phishers are able to craft postings and messages targeting groups of victims, or specific individuals. The end game is to funnel victims to landing pages. …more

Q&A: The drivers behind the stark rise — and security implications — of ‘memory attacks’

By Byron V. Acohido

A distinctive class of hacking is rising to the fore and is being leveraged by threat actors to carry out deep, highly resilient intrusions of well-defended company networks.

These attacks are referred to in the security community as “fileless attacks” or “memory attacks.” The latter conveys a more precise picture: memory hacking refers to a broad set of practices, which can include fileless attacks, that constitute this go-deep form of network break-ins.

I had the chance at RSA 2019 to discuss memory hacking with Willy Leichter, vice president of marketing, and Shauntinez Jakab, director of product marketing, at Virsec, a San Jose-based supplier of advanced application security and memory protection technologies.

They walked me through how threat actors are cleverly slipping snippets of malicious code past perimeter defenses and then executing their payloads – undetected while applications are live, running in process memory.

For a long time, memory hacking was the exclusive province of nation-state backed operatives. But over the past couple of years, memory attacks have come into regular use by common cybercriminals. Garden-variety threat actors are now leveraging memory hacking tools and techniques to gain footholds, move laterally and achieve persistence deep inside well-defended networks.

For a comprehensive drill down, please view the accompanying YouTube video of my full interview with Leichter and Jakab at RSA 2019’s broadcast alley. Here are excerpts, edited for clarity and length:
