Navigating ICS Security: The Value of Frameworks

Since the implementation of the General Data Protection Regulation (GDPR) on 25 May 2018, organizations and even private citizens have globally begun to re-assess what it means to ‘take security seriously’ and to better understand the massive difference between security and privacy. What you may not be familiar with is the Network and Information Systems […]… Read More

The Hidden Cost of Ransomware: Wholesale Password Theft

Organizations in the throes of cleaning up after a ransomware outbreak typically will change passwords for all user accounts that have access to any email systems, servers and desktop workstations within their network. But all too often, ransomware victims fail to grasp that the crooks behind these attacks can and frequently do siphon every single password stored on each infected endpoint. The result of this oversight may offer attackers a way back into the affected organization, access to financial and healthcare accounts, or — worse yet — key tools for attacking the victim’s various business partners and clients.

In mid-November 2019, Wisconsin-based Virtual Care Provider Inc. (VCPI) was hit by the Ryuk ransomware strain. VCPI manages the IT systems for some 110 clients that serve approximately 2,400 nursing homes in 45 U.S. states. VCPI declined to pay the multi-million dollar ransom demanded by their extortionists, and the attack cut off many of those elder care facilities from their patient records, email and telephone service for days or weeks while VCPI rebuilt its network.

Just hours after that story was published, VCPI chief executive and owner Karen Christianson reached out to say she hoped I would write a follow-up piece about how they recovered from the incident. My reply was that I’d consider doing so if there was something in their experience that I thought others could learn from their handling of the incident.

I had no inkling at the time of how much I would learn in the days ahead.

EERIE EMAILS

On December 3, I contacted Christianson to schedule a follow-up interview for the next day. On the morning of Dec. 4 (less than two hours before my scheduled call with VCPI and more than two weeks after the start of their ransomware attack) I heard via email from someone claiming to be part of the criminal group that launched the Ryuk ransomware inside VCPI.

That email was unsettling because its timing suggested that whoever sent it somehow knew I was going to speak with VCPI later that day. This person said they wanted me to reiterate a message they’d just sent to the owner of VCPI stating that their offer of a greatly reduced price for a digital key needed to unlock servers and workstations seized by the malware would expire soon if the company continued to ignore them.

“Maybe you chat to them lets see if that works,” the email suggested.

The anonymous individual behind that communication declined to provide proof that they were part of the group that held VPCI’s network for ransom, and after an increasingly combative and personally threatening exchange of messages soon stopped responding to requests for more information.

“We were bitten with releasing evidence before hence we have stopped this even in our ransoms,” the anonymous person wrote. “If you want proof we have hacked T-Systems as well. You may confirm this with them. We havent [sic] seen any Media articles on this and as such you should be the first to report it, we are sure they are just keeping it under wraps.” Security news site Bleeping Computer reported on the T-Systems Ryuk ransomware attack on Dec. 3.

In our Dec. 4 interview, VCPI’s acting chief information security officer — Mark Schafer, CISO at Wisconsin-based SVA Consulting — confirmed that the company received a nearly identical message that same morning, and that the wording seemed “very similar” to the original extortion demand the company received.

However, Schafer assured me that VCPI had indeed rebuilt its email network following the intrusion and strictly used a third-party service to discuss remediation efforts and other sensitive topics.

‘LIKE A COMPANY BATTLING A COUNTRY’

Christianson said several factors stopped the painful Ryuk ransomware attack from morphing into a company-ending event. For starters, she said, an employee spotted suspicious activity on their network in the early morning hours of Saturday, Nov. 16. She said that employee then immediately alerted higher-ups within VCPI, who ordered a complete and immediate shutdown of the entire network.

“The bottom line is at 2 a.m. on a Saturday, it was still a human being who saw a bunch of lights and had enough presence of mind to say someone else might want to take a look at this,” she said. “The other guy he called said he didn’t like it either and called the [chief information officer] at 2:30 a.m., who picked up his cell phone and said shut it off from the Internet.”

Schafer said another mitigating factor was that VCPI had contracted with a third-party roughly six months prior to the attack to establish off-site data backups that were not directly connected to the company’s infrastructure.

“The authentication for that was entirely separate, so the lateral movement [of the intruders] didn’t allow them to touch that,” Schafer said.

Schafer said the move to third-party data backups coincided with a comprehensive internal review that identified multiple areas where VCPI could harden its security, but that the attack hit before the company could complete work on some of those action items.

“We did a risk assessment which was pretty much spot-on, we just needed more time to work on it before we got hit,” he said. “We were doing the right things, just not fast enough. If we’d had more time to prepare, it would have gone better. I feel like we were a company battling a country. It’s not a fair fight, and once you’re targeted it’s pretty tough to defend.”

WHOLESALE PASSWORD THEFT

Just after receiving a tip from a reader about the ongoing Ryuk infestation at VCPI, KrebsOnSecurity contacted Milwaukee-based Hold Security to see if its owner Alex Holden had any more information about the attack. Holden and his team had previously intercepted online traffic between and among multiple ransomware gangs and their victims, and I was curious to know if that held true in the VCPI attack as well.

Sure enough, Holden quickly sent over several logs of data suggesting the attackers had breached VCPI’s network on multiple occasions over the previous 14 months.

“While it is clear that the initial breach occurred 14 months ago, the escalation of the compromise didn’t start until around November 15th of this year,” Holden said at the time. “When we looked at this in retrospect, during these three days the cybercriminals slowly compromised the entire network, disabling antivirus, running customized scripts, and deploying ransomware. They didn’t even succeed at first, but they kept trying.”

Holden said it appears the intruders laid the groundwork for the VPCI using Emotet, a powerful malware tool typically disseminated via spam.

“Emotet continues to be among the most costly and destructive malware,” reads a July 2018 alert on the malware from the U.S. Department of Homeland Security. “Its worm-like features result in rapidly spreading network-wide infection, which are difficult to combat.”

According to Holden, after using Emotet to prime VCPI’s servers and endpoints for the ransomware attack, the intruders deployed a module of Emotet called Trickbot, which is a banking trojan often used to download other malware and harvest passwords from infected systems.

Indeed, Holden shared records of communications from VCPI’s tormentors suggesting they’d unleashed Trickbot to steal passwords from infected VCPI endpoints that the company used to log in at more than 300 Web sites and services, including:

-Identity and password management platforms Auth0 and LastPass
-Multiple personal and business banking portals;
-Microsoft Office365 accounts
-Direct deposit and Medicaid billing portals
-Cloud-based health insurance management portals
-Numerous online payment processing services
-Cloud-based payroll management services
-Prescription management services
-Commercial phone, Internet and power services
-Medical supply services
-State and local government competitive bidding portals
-Online content distribution networks
-Shipping and postage accounts
-Amazon, Facebook, LinkedIn, Microsoft, Twitter accounts

Toward the end of my follow-up interview with Schafer and VCPI’s Christianson, I shared Holden’s list of sites for which the attackers had apparently stolen internal company credentials. At that point, Christianson abruptly ended the interview and got off the line, saying she had personal matters to attend to. Schafer thanked me for sharing the list, noting that it looked like VCPI probably now had a “few more notifications to do.”

Moral of the story: Companies that experience a ransomware attack — or for that matter any type of equally invasive malware infestation — should assume that all credentials stored anywhere on the local network (including those saved inside Web browsers and password managers) are compromised and need to be changed.

Out of an abundance of caution, this process should be done from a pristine (preferably non-Windows-based) system that does not reside within the network compromised by the attackers. In addition, full use should be made of the strongest method available for securing these passwords with multi-factor authentication.

The Everyday Cyber Threat Landscape: Trends from 2019 to 2020

The past 12 months have been another bumper year for cybercrime affecting everyday users of digital technology. Trend Micro blocked more than 26.8 billion of these threats in the first half of 2019 alone. The bad news is that there are many more out there waiting to steal your personal data for identity fraud, access your bank account, hold your computer to ransom, or extort you in other ways.

To help you stay safe over the coming year we’ve listed some of the biggest threats from 2019 and some trends to keep an eye on as we hit the new decade. As you’ll see, many of the most dangerous attacks will look a lot like the ones we warned about in 2019.

As we enter 2020 the same rules apply: stay alert, stay sceptical, and stay safe by staying protected.

Top five threats of 2019

Cybercrime is a chaotic, volatile world. So to make sense of the madness of the past 12 months, we’ve broken down the main type of threats consumers encountered into five key areas:

Home network threats: Our homes are increasingly powered by online technologies. Over two-thirds (69%) of US households now own at least one smart home device: everything from voice assistant-powered smart speakers to home security systems and connected baby monitors. But gaps in protection can expose them to hackers. As the gateway to our home networks, routers are particularly at risk. It’s a concern that 83% are vulnerable to attack. There were an estimated 105m smart home attacks in the first half of 2019 alone.

Endpoint threats: These are attacks aimed squarely at you the user, usually via the email channel. Trend Micro detected and blocked more than 26 billion such email threats in the first half of 2019, nearly 91% of the total number of cyber-threats. These included phishing attacks designed to trick you into clicking on a malicious link to steal your personal data and log-ins or begin a ransomware download. Or they could be designed to con you into handing over your personal details, by taking you to legit-looking but spoofed sites. Endpoint threats sometimes include social media phishing messages or even legitimate websites that have been booby-trapped with malware.

Mobile security threats: Hackers are also targeting our smartphones and tablets with greater gusto. Malware is often unwittingly downloaded by users, since it’s hidden in normal-looking Android apps, like the Agent Smith adware that infected over 25 million handsets globally this year. Users are also extra-exposed to social media attacks and those leveraging unsecured public Wi-Fi when using their devices. Once again, the end goal for the hackers is to make money: either by stealing your personal data and log-ins; flooding your screen with adverts; downloading ransomware; or forcing your device to contact expensive premium rate phone numbers that they own.

Online accounts under attack: Increasingly, hackers are after our log-ins: the virtual keys that unlock our digital lives. From Netflix to Uber, webmail to online banking, access to these accounts can be sold on the dark web or they can be raided for our personal identity data. Individual phishing attacks is one way to get these log-ins. But an increasingly popular method in 2019 was to use automated tools that try tens of thousands of previously breached log-ins to see if any of them work on your accounts. From November 2017 through the end of March 2019, over 55 billion such attacks were detected.

Breaches are everywhere: The raw materials needed to unlock your online accounts and help scammers commit identity fraud are stored by the organizations you interact with online. Unfortunately, these companies continued to be successfully targeted by data thieves in 2019. As of November 2019, there were over 1,200 recorded breaches in the US, exposing more than 163 million customer records. Even worse, hackers are now stealing card data direct from the websites you shop with as they are entered in, via “digital skimming” malware.

What to look out for in 2020

Smart homes under siege: As we invest more money in smart gadgets for our families, expect hackers to double down on network attacks. There’s a rich bounty for those that do: they can use an exposed smart endpoint as a means to sneak into your network and rifle through your personal data and online accounts. Or they could monitor your house via hacked security cameras to understand the best time to break in. Your hacked devices could even be recruited into botnets to help the bad guys attack others.

Social engineering online and by phone: Attacks that target user credulity are some of the most successful. Expect them to continue in 2020: both traditional phishing emails and a growing number of phone-based scams. Americans are bombarded by 200 million automated “robocalls” each day, 30% of which are potentially fraudulent. Sometimes phone fraud can shift quickly online; for example, tech support scams that convince the user there’s something wrong with their PC. Social engineering can also be used to extort money, such as in sextortion scams designed to persuade victims that the hacker has and is about to release a webcam image of them in a “compromising position.” Trend Micro detected a 319% increase in these attacks from 2H 2018 to the first half of 2019.

Threats on the move: Look out for more mobile threats in 2020. Many of these will come from unsecured public Wi-Fi which can let hackers eavesdrop on your web sessions and steal identity data and log-ins. Even public charging points can be loaded with malware, something LA County recently warned about. This comes on top of the escalating threat from malicious mobile apps.

All online accounts are fair game: Be warned that almost any online account you open and store personal data in today will be a target for hackers tomorrow. For 2020, this means of course you will need to be extra careful about online banking. But also watch out for attacks on gaming accounts.  Not only your personal identity data and log-ins but also lucrative in-game tokens will become highly sought after. Twelve billion of those recorded 55 billion credential stuffing attacks were directed at the gaming industry.

Worms make a comeback: Computer worms are dangerous because they self-replicate, allowing hackers to spread attacks without user interaction. This is what happened with the WannaCry ransomware attacks of 2017. A Microsoft flaw known as Bluekeep offers a new opportunity to cause havoc in 2020. There may be more out there.

How to stay safe

Given the sheer range of online threats facing computer users in 2020, you’ll need to cover all bases to keep your systems and data safe. That means:

Protecting the smart home with network monitoring solutions, regular checks for security updates on gadgets/router, changing the factory default logins to strong passwords, and putting all gadgets onto a guest network.

Tackling data-stealing malware, ransomware and other worm-style threats with strong AV from a reputable vendor, regular patching of your PC/mobile device, and strong password security (as given below).

Staying safe on the move by always using VPNs with public Wi-Fi, installing AV on your device, only frequenting official app stores, and ensuring you’re always on the latest device OS version. And steer clear of public USB charging points.

Keeping accounts secure by using a password manager for creating and storing strong passwords and/or switching on two-factor authentication where available. This will stop credential stuffing in its tracks and mitigate the impact of a third-party breach of your log-ins. Also, never log-in to webmail or other accounts on shared computers.

Taking on social engineering by never clicking on links or opening attachments in unsolicited emails, texts or social media messages and never giving out personal info over the phone.

Defending businesses from the perils of Cryptojacking

Estimated reading time: 2 minutes

The last few years have given rise to a new & dangerous cyberthreat known as cryptojacking which is unlike typical malware — it does not demand ransom, spy or cripple enterprise systems or cause loss of data. We introduced the subject earlier and are re-iterating on the same with few additional pointers.

Enterprises should take this threat very seriously!

Increase in Cryptojacking attacks

In 2018, an Economic Times report observed that hackers were mining a fortune by running cryptocurrency scripts on Indian government websites, including the director of municipal administration of Andhra Pradesh, Tirupati Municipal Corporation and Macherla municipality. Seqrite’s Threat Report Q2 2019 also detected 19k cryptojacking attacks as against 17K in Q1, 2019 illustrating how this threat is seeing a rapid upsurge.

Since we already shared insights on the functionality of cryptojacking, here is some information on why cryptojacking is getting popular among the hacker community.

Why is Cryptojacking popular?

Less risk! Hackers love Cryptojacking because it is way less risky than planting ransomware in enterprise systems. In businesses worldwide, awareness of ransomware has grown. Hence, stakeholders are applying better and advanced solutions to protect against the same. This is not the same with Cryptojacking as this technique of infecting business machines is new.

While hackers can convince, say 4-5 businesses to pay, out of a 100 that they attack via ransomware, in cryptojacking they can ensure that all 100 machines that they attack work at full capacity to mine for cryptocurrency. This hacking technique is also very simple and does not require high technical skills. Cryptojacking kits can be easily picked up from the dark web for as less as $30.

For enterprises, cryptojacking attacks can lead to server outages and high costs of consumption. To prevent these attacks, they need to take the below-mentioned measures –

Ensure endpoint protection can detect these threats

As a threat which is on the rise, it is important for enterprises to update the endpoint protection solution they are using so they are able to detect and block cryptojacking threats. While like all other cyber threats, where the methods may constantly change, an updated security solution, such as Seqrite’s Endpoint Security, can detect and prevent cryptojacking attacks from happening.

Browser protection is key

Cryptojacking spreads by getting users to click on malicious links on websites which lead to the miner being installed on a system. The way to prevent this from happening is ensuring that browsers in the enterprise have strong protection installed which can prevent these scripts from running.

Use web filtering to block suspicious websites

Along with browser protection, it can be a good idea for enterprises to go one step further and use their web filtering solutions to block websites suspected of malicious activities such as cryptojacking from being accessed.

A strong MDM solution is important

Mobile Device Management (MDM) solutions like the Seqrite mSuite can prevent mobile devices from being infected by cryptojacking software offering cybersecurity for businesses that are also on-the-go.

Seqrite’s Unified Threat Management (UTM) solution offers ease of use and brings key security features such as network security, management, backup and recovery of data and other critical network services together under a single unified umbrella, preventing cryptojacking attacks at the source.
