Supply-Chain Attack against the Electron Development Platform

Electron is a cross-platform development system for many popular communications apps, including Skype, Slack, and WhatsApp. Security vulnerabilities in the update system allows someone to silently inject malicious code into applications. From a news article:

At the BSides LV security conference on Tuesday, Pavel Tsakalidis demonstrated a tool he created called BEEMKA, a Python-based tool that allows someone to unpack Electron ASAR archive files and inject new code into Electron’s JavaScript libraries and built-in Chrome browser extensions. The vulnerability is not part of the applications themselves but of the underlying Electron framework — and that vulnerability allows malicious activities to be hidden within processes that appear to be benign. Tsakalidis said that he had contacted Electron about the vulnerability but that he had gotten no response — and the vulnerability remains.

While making these changes required administrator access on Linux and MacOS, it only requires local access on Windows. Those modifications can create new event-based “features” that can access the file system, activate a Web cam, and exfiltrate information from systems using the functionality of trusted applications — including user credentials and sensitive data. In his demonstration, Tsakalidis showed a backdoored version of Microsoft Visual Studio Code that sent the contents of every code tab opened to a remote website.

Basically, the Electron ASAR files aren’t signed or encrypted, so modifying them is easy.

Note that this attack requires local access to the computer, which means that an attacker that could do this could do much more damaging things as well. But once an app has been modified, it can be distributed to other users. It’s not a big deal attack, but it’s a vulnerability that should be closed.

Backdoor Built into Android Firmware

In 2017, some Android phones came with a backdoor pre-installed:

Criminals in 2017 managed to get an advanced backdoor preinstalled on Android devices before they left the factories of manufacturers, Google researchers confirmed on Thursday.

Triada first came to light in 2016 in articles published by Kaspersky here and here, the first of which said the malware was “one of the most advanced mobile Trojans” the security firm’s analysts had ever encountered. Once installed, Triada’s chief purpose was to install apps that could be used to send spam and display ads. It employed an impressive kit of tools, including rooting exploits that bypassed security protections built into Android and the means to modify the Android OS’ all-powerful Zygote process. That meant the malware could directly tamper with every installed app. Triada also connected to no fewer than 17 command and control servers.

In July 2017, security firm Dr. Web reported that its researchers had found Triada built into the firmware of several Android devices, including the Leagoo M5 Plus, Leagoo M8, Nomu S10, and Nomu S20. The attackers used the backdoor to surreptitiously download and install modules. Because the backdoor was embedded into one of the OS libraries and located in the system section, it couldn’t be deleted using standard methods, the report said.

On Thursday, Google confirmed the Dr. Web report, although it stopped short of naming the manufacturers. Thursday’s report also said the supply chain attack was pulled off by one or more partners the manufacturers used in preparing the final firmware image used in the affected devices.

This is a supply chain attack. It seems to be the work of criminals, but it could just as easily have been a nation-state.

More Attacks against Computer Automatic Update Systems

Last month, Kaspersky discovered that Asus’s live update system was infected with malware, an operation it called Operation Shadowhammer. Now we learn that six other companies were targeted in the same operation.

As we mentioned before, ASUS was not the only company used by the attackers. Studying this case, our experts found other samples that used similar algorithms. As in the ASUS case, the samples were using digitally signed binaries from three other Asian vendors:

Electronics Extreme, authors of the zombie survival game called Infestation: Survivor Stories,

Innovative Extremist, a company that provides Web and IT infrastructure services but also used to work in game development,

Zepetto, the South Korean company that developed the video game Point Blank.

According to our researchers, the attackers either had access to the source code of the victims’ projects or they injected malware at the time of project compilation, meaning they were in the networks of those companies. And this reminds us of an attack that we reported on a year ago: the CCleaner incident.

Also, our experts identified three additional victims: another video gaming company, a conglomerate holding company and a pharmaceutical company, all in South Korea. For now we cannot share additional details about those victims, because we are in the process of notifying them about the attack.

Me on supply chain security.

China Spying on Undersea Internet Cables

Supply chain security is an insurmountably hard problem. The recent focus is on Chinese 5G equipment, but the problem is much broader. This opinion piece looks at undersea communications cables:

But now the Chinese conglomerate Huawei Technologies, the leading firm working to deliver 5G telephony networks globally, has gone to sea. Under its Huawei Marine Networks component, it is constructing or improving nearly 100 submarine cables around the world. Last year it completed a cable stretching nearly 4,000 miles from Brazil to Cameroon. (The cable is partly owned by China Unicom, a state-controlled telecom operator.) Rivals claim that Chinese firms are able to lowball the bidding because they receive subsidies from Beijing.

Just as the experts are justifiably concerned about the inclusion of espionage “back doors” in Huawei’s 5G technology, Western intelligence professionals oppose the company’s engagement in the undersea version, which provides a much bigger bang for the buck because so much data rides on so few cables.

This shouldn’t surprise anyone. For years, the US and the Five Eyes have had a monopoly on spying on the Internet around the globe. Other countries want in.

As I have repeatedly said, we need to decide if we are going to build our future Internet systems for security or surveillance. Either everyone gets to spy, or no one gets to spy. And I believe we must choose security over surveillance, and implement a defense-dominant strategy.

Malware Installed in Asus Computers through Hacked Update Process

Kaspersky Labs is reporting on a new supply chain attack they call “Shadowhammer.”

In January 2019, we discovered a sophisticated supply chain attack involving the ASUS Live Update Utility. The attack took place between June and November 2018 and according to our telemetry, it affected a large number of users.

[…]

The goal of the attack was to surgically target an unknown pool of users, which were identified by their network adapters’ MAC addresses. To achieve this, the attackers had hardcoded a list of MAC addresses in the trojanized samples and this list was used to identify the actual intended targets of this massive operation. We were able to extract more than 600 unique MAC addresses from over 200 samples used in this attack. Of course, there might be other samples out there with different MAC addresses in their list.

We believe this to be a very sophisticated supply chain attack, which matches or even surpasses the Shadowpad and the CCleaner incidents in complexity and techniques. The reason that it stayed undetected for so long is partly due to the fact that the trojanized updaters were signed with legitimate certificates (eg: “ASUSTeK Computer Inc.”). The malicious updaters were hosted on the official liveupdate01s.asus[.]com and liveupdate01.asus[.]com ASUS update servers.

The sophistication of the attack leads to the speculation that a nation-state — and one of the cyber powers — is responsible.

As I have previously written, supply chain security is “an incredibly complex problem.” These attacks co-opt the very mechanisms we need to trust for our security. And the international nature of our industry results in an array of vulnerabilities that are very hard to secure.

Kim Zetter has a really good article on this. Check if your computer is infected here, or use this diagnostic tool from Asus.

That Bloomberg Supply-Chain-Hack Story

Back in October, Bloomberg reported that China has managed to install backdoors into server equipment that ended up in networks belonging to — among others — Apple and Amazon. Pretty much everybody has denied it (including the US DHS and the UK NCSC). Bloomberg has stood by its story — and is still standing by it.

I don’t think it’s real. Yes, it’s plausible. But first of all, if someone actually surreptitiously put malicious chips onto motherboards en masse, we would have seen a photo of the alleged chip already. And second, there are easier, more effective, and less obvious ways of adding backdoors to networking equipment.

Friday Squid Blogging: Squid Falsely Labeled as Octopus

Two New Yorkers have been charged with importing squid from Peru and then reselling it as octopus.

Yet another problem that a blockchain-enabled supply-chain system won’t solve.

As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.
