Very Creative Phishing Attack

It all starts with a calendar invite, but there is a setup. The con is that your bank account has been compromised and you need to fix it.

The attack starts with an email titled (like) “Fraud Detection from Message Center”. This part of the attack uses a real but compromised Office 365 account, complete with legit email security like DKIM and SPF.

The invite is hosted on the real Office 365 Sharepoint.com and contains a link. Clicking on the link causes another relatively simple document to open with another link.

Since hackers are equal opportunity crooks, when the user clicks on this link, they get transferred to a phishing site hosted at Google where the user is presented with a very convincing Wells Fargo site page.

The user is then prompted for the login information, PIN, various account number details and email credentials.

Assuming the user falls for all of this, they are taken to a legitimate Wells Fargo login page designed to make the user think the account was secured, when in fact, the user just gave the hacker the keys to the cookie jar. And likely all of his or her money.

According to the security vendor (Cofence), this is not the first time that hackers have used Google’s infrastructure to host malware. Credit: SC Magazine

So what should you be doing?

Education. Education. Education.

Anti-phishing training should be a requirement at all companies and for all employees. At the low end there is free training, but for most companies, there is a moderate cost solution that is highly effective.

Some companies send the same phishing email to everyone, maybe once a quarter. That is not an effective approach to train employees. The program needs to be much more active in order to be effective.

As you can see from the sophistication of the attack above, the hackers are working overtime to steal your money.

You need to work equally hard to protect it.

Anonymous Gonna Rise Again. Question Mark?

A hacker or hackers claiming to be affiliated the non-group Anonymous has posted a million documents coming from over 200 police departments and other law enforcement agencies. While the documents do no purport to show illegal activities, they are likely both embarrassing and also confidential. The fact that the police could not protect their own information is probably not great for their reputations either. Credit: Wired

Republican Senators Create Bill to End Use of Warrant-proof Encryption

Senators Lindsey Graham, Tom Cotton and Marsha Blackburn say that they plan to introduce a bill that will require service providers and device manufacturers to insert backdoors into their software and devices so that cops can decrypt the devices when they want to.

They have not published the bill yet and we have no idea whether it will get any traction, so who knows, but the main issue is that there is nothing to stop bad actors from installing software from web sites in countries that don’t really case about what Mrs Graham and Cotton or Ms. Blackburn want. Sure you will catch stupid crooks, but we catch them anyway. Credit: ZDNet

Pentagon Creates List of Companies Controlled by Chinese PLA

There is a 1999 law that requires the Pentagon to produce a list of companies controlled by the Chinese military. Always prompt, 21 years later the Pentagon has produced that list. Huawei is one of those companies, of course. At this point it is not clear what the White House will do with that list, but we assume that it will be used to add pressure to China. Credit: Time

Feds Ask FCC to Deny China Access to New Fiber Optic Cable from US

Team Telecom, that federation of executive branch agencies that has been completely toothless in stopping China from compromising our telecom has finally decided that to feels its Wheaties. Renamed CAFPUSTSS, they say we should not drop an undersea fiber cable in Hong Kong for China to tap. The proposed cable would have a speed of 144 terabits per second, otherwise known as way fast. If the White House has its way, the cable will go from the U.S. to the Philippines and Taiwan and bypass Hong Kong. Google owns the Taiwan segment and Facebook owns the Philippines segment, but China owns the proposed Hong Kong segment. Credit: CSO Online

Hackers Use Captcha to Thwart Detection

Captcha, those annoying puzzles/questions/pictures that websites use to try and distinguish bots from humans, is now being used by the baddies. The hackers are putting their malware, like infected spreadsheets, on websites behind a captcha, likely to try and avoid detection by the good guys. If the good guys automated testing cannot complete the captcha, it won’t test the content behind it, leaving it available for victims to download and get infected. Credit: ARS Technica

Chinese Bank Forced Western Companies to Install Malware

Security firm Trustwave has discovered malware laced tax software in two of it’s western customer’s networks after they opened offices in China.

The bank said the software was required to pay local taxes. In fact the software did perform that function.

Trustwave calls this malware GoldenSpy and said that it installed a backdoor in their client’s computer. The backdoor allowed the Chinese to connect to the computer, install other malware and run Windows commands.

GoldenSpy installs two copies of itself and will automatically reinstall itself if one of the copies is discovered. It also has other self-protection measures.

It also waits two hours after the tax software is installed to silently install the backdoors.

There is no way to prove how the malware got there, but given they are in China and a western company, you can draw your own conclusions. Credit: ZDNet

Okay, so what does this mean?

It is not completely clear, but certainly it raises some questions.

Assuming you are not doing business in China, should you worry?

There is nothing special about the technique used and, in fact, the NSA is reported to have used it against folks that they want to monitor.

The technique could be used by

  • Competitors
  • Hackers
  • Nation state actors
  • and probably a host of others

Since *you* installed the software voluntarily, most of the security controls in your system will not detect it.

We have seen a number of attacks like this over the years. Sometimes hackers compromise a developer’s computer and insert the malware there. That way, when it gets checked in and compiled, it is not detected.

But that is only one way the malware can get there.

Traditional anti-virus/anti-malware software will not detect this.

What will detect this is software similar to Trustwave. They do managed security services (we offer a similar product that is well suited to small businesses).

What the software needs to do is detect unusual behavior like accessing data that it should not, connecting to web sites that it should not, installing software etc.

Generally interpreting what the alerts mean requires an expert.

What is less clear is how frequently this happens because most companies do not have software/services like these companies did. There also are no laws requiring companies to report these types of attacks unless the company is publicly traded and the attack materially affects the company’s balance sheet.

Assuming that the software doesn’t break anything, it likely would go undetected. Forever!

If you do not have anything in place to detect this type of malware, you should definitely consider it.

Historically, these types of attacks are designed to steal intellectual property. IP Theft is more difficult to detect because there are no systems in place nationally to detect these types of theft like there is for credit card fraud. In addition, IP theft has a long shelf life. If you steal information about a company’s business processes, for example, that information will be valuable until the company no longer uses those business processes, which could be decades later.

If the IP theft is controlled by a competitor, then that competitor could use that information to unfairly compete with the company who’s information was stolen.

The New Normal – Not So Secure

Facebook says that 50% of its employees could be working remotely in 5 years.

My guess is that this could be the new normal, which is not so good if you own a lot of expensive commercial real estate in a big down town.

Zuck also says that employees that move from say San Francisco or New York and work remotely from Kansas may have the pay “adjusted”. Likely downward, which is another motivation for companies – lower payroll, which means lower payroll taxes and less rent.

I think that is going to be the new normal. Companies have figured out over the last 3 months that people can be productive without sitting in a cube. In some cases, more productive. And, if you remove the distractions of kids at home and the economy in the toilet, they might be a lot more productive.

Which brings me to today’s story.

IBM released a study on work from home security. IBM is not some fly-by-night company. Sure everyone can be wrong sometimes, but this report aligns with a lot of other information I have seen. Here are some of the details.

  • Over half of the people they asked are not aware or unsure of any company security policies around the following areas with slightly lower percents for other policies-
    • Mobile device management (53%)
    • Password managers (51%)
    • Collaboration tools (52%)
  • 45% said that their employer had not provided any special training on protecting the security of devices while working from home
  • 93% said they are confident of their company’s ability to keep information secure even though 52% are using their personal computers for work, often with no new security tools.
  • More than 50% of new work from home employees are using their home computers for work but 61% said that their employer had not given them any tools to secure those devices.

So what does this mean?

It means that if some percentage of employees will be permanently working from home, what do you need to do regarding security?

We already know that hackers are taking advantage of the current situation. If that remains “profitable” (which means money or information), they will continue.

Money, such as business email compromise attacks, spear phishing and whale phishing will likely be detected soon after the attack is launched.

Attacks which only seek to stay inside your system undetected, well, those will work hard to remain, undetected. The longest such attack I am familiar with remained undetected for 12 years. The company eventually filed for bankruptcy and was sold for spare change.

So, as managers, it is your call. Do you beef up your security program? Or, do you collect spare change?

Your choice.

Ripple20 Vulnerability Affects 100s of Millions of IoT/IIoT and Medical Devices

If that headline doesn’t scare you, it should.

Ripple20 is a family of 19 vulnerabilities that are part of a library that is used in medical devices, home automation devices, oil & gas controls, networking devices and other industrial control devices.

The bugs are in a library that was developed in the 1990s and is integrated into all kinds of devices.

The problem is that these libraries are not something that a user – consumer or business – can do anything about. They are completely dependent on the manufacturer to fix it.

Likely many of these devices don’t even have a mechanism to update it.

To make things even more troubling, many times the buggy software was integrated into modules that then got integrated into products that then got sold to you and me. The software vendor has no idea where it got used and the integrator might not even know that the affected modules are in their product.

The product is a TCP/IP communications library – something that any device that is somehow connected to the Internet has in it.

So why were 19 vulnerabilities called Ripple20? Because, they say, of the ripple effect they will have in 2020. That is a bit of an understatement.

Some of the vulnerabilities have a risk rating of 10 out of 10 and others 9.8 out of 10.

While the software vendor has released patches for the current version of the software, what about products that were built 10 years ago for example? Those companies may not even be in business and even if they are, they likely don’t support a (pick a number) 10 year old, 15 year old or whatever age product. Assuming they know about the library.

Vendors that have released alerts include Intel, HP, Schneider Electric, Caterpillar, B.Braun, Green Hills, Rockwell Automation and Cisco.

Expect more alerts over the coming months.

The industry is still working through the impact of the Urgent/11 family of similar bugs that were released about a year ago.

The government is working on some voluntary guidance for Software Bill of Materials standards that I am watching, but that is going to take years to gain any traction.

Businesses need to keep pushing vendors and vendors need to keep pushing their vendors for a Software Bill of Materials to be a standard part of all deliverables. Software developers need to step up their game too.

Until then, we are making it very easy for the hackers. They know what the vulnerabilities are. They know at least some of the vendors that are affected and, more importantly, they know that most of these products will never be patched. Likely in a matter of days or maybe a week then entire Internet will be scanned looking for vulnerable devices. Then hackers have years to exploit it.

While a hacker turning off your smart light bulb might be annoying, changing the settings on an insulin pump – well that could have more life altering effects.

Ponder this: Software vendors have zero liability for these bugs. Congress is considering changing that (it is a recommendation of the Cyberspace Solarium Report). Until that happens, don’t expect that to change.

Singapore Updates Contact Tracing App

Singapore is not exactly a democracy, so this isn’t a complete surprise. They are updating their contact tracing app to include foreigner’s passport number and scanning of barcodes to facilitate tracking when someone enters a store or mall or restaurant. They would like the program to run in the background, but Apple does not allow Bluetooth to be active in the background, so the software doesn’t work right on iPhones. So, for iPhone users, people who don’t have smartphones and people who won’t install the app, they are working on building a wearable device to perform the same function and possibly issuing a device to everyone in the country.

Indian IT Company Ran Hack for Hire Operation

BellTroX, a small Indian IT company based in Delhi, ran (allegedly) a hack-for-hire operation that targeted thousands of high profile politicians, investors and journalists on six continents over the last 7 years. Initially thought to be state sponsored, investigators now think they were just in it for the money. The group is known as Dark Basin by researchers, who have begun to unravel their work and notify hacked individuals. Credit: The Hacker News

Thanos Ransomware as a Service Weaponizes RIPlace Vulnerability

Thanos Ransomware as a Service tool weaponizes the Windows RIPlace attack tactic. RIPlace is a technique that uses a legacy API to bypass enpoint protection (AKA anti-virus) tools. That that Thanos is available as a service to any wanna hacker, expect to see even more ransomware attacks. The Thanos developer continues to add features including a light version (as in less features) and a company (full featured) version. Credit: Threatpost

Copy Protection Comes in Many Flavors

GE has, apparently, “copy protected” the water filters for their refrigerators so that you cannot use a $13 filter that is physically the same and have to pay GE $55 for their filter.

One customer was sufficiently annoyed that he bought a domain, www.GEFilterGate.com and explained how to “hack” GE’s refrigerator. All you have to do it take GE’s RFID tag off a legit filter and put it in the right place on the fake GE filter. I am not sure if it is legal, but that was one ticked off user. Credit: Vice

Federal Agencies Spending Millions on Crossbow

Crossbow, AKA Stingray, version 2, has been purchased by multiple federal agencies including ICE. Stingray is a device made by Harris to intercept cell phone traffic and is used by the military. They are also being used by federal, state and local governments, including during protests. Think of it as a cell tower in a small suitcase. Whether version 1 or version 2, they can be used to track down fugitives or surveil anyone, anywhere. We have reports of finding many Stingrays around Washington, DC, likely placed there by UNfriendly countries. Harris was so keen to keep information about the Stingray quiet that police regularly dropped charges rather than reveal information. Assume that Crossbow will be the same. Credit: Vice
