Software Vulnerabilities in the Boeing 787

Boeing left its software unprotected, and researchers have analyzed it for vulnerabilities:

At the Black Hat security conference today in Las Vegas, Santamarta, a researcher for security firm IOActive, plans to present his findings, including the details of multiple serious security flaws in the code for a component of the 787 known as a Crew Information Service/Maintenance System. The CIS/MS is responsible for applications like maintenance systems and the so-called electronic flight bag, a collection of navigation documents and manuals used by pilots. Santamarta says he found a slew of memory corruption vulnerabilities in that CIS/MS, and he claims that a hacker could use those flaws as a foothold inside a restricted part of a plane’s network. An attacker could potentially pivot, Santamarta says, from the in-flight entertainment system to the CIS/MS to send commands to far more sensitive components that control the plane’s safety-critical systems, including its engine, brakes, and sensors. Boeing maintains that other security barriers in the 787’s network architecture would make that progression impossible.

Santamarta admits that he doesn’t have enough visibility into the 787’s internals to know if those security barriers are circumventable. But he says his research nonetheless represents a significant step toward showing the possibility of an actual plane-hacking technique. “We don’t have a 787 to test, so we can’t assess the impact,” Santamarta says. “We’re not saying it’s doomsday, or that we can take a plane down. But we can say: This shouldn’t happen.”

Boeing denies that there’s any problem:

In a statement, Boeing said it had investigated IOActive’s claims and concluded that they don’t represent any real threat of a cyberattack. “IOActive’s scenarios cannot affect any critical or essential airplane system and do not describe a way for remote attackers to access important 787 systems like the avionics system,” the company’s statement reads. “IOActive reviewed only one part of the 787 network using rudimentary tools, and had no access to the larger system or working environments. IOActive chose to ignore our verified results and limitations in its research, and instead made provocative statements as if they had access to and analyzed the working system. While we appreciate responsible engagement from independent cybersecurity researchers, we’re disappointed in IOActive’s irresponsible presentation.”

This being Black Hat and Las Vegas, I’ll say it this way: I would bet money that Boeing is wrong. I don’t have an opinion about whether or not it’s lying.

EDITED TO ADD (9/12): IOActive‘s paper has technical details. There is some belief that these are the same vulnerabilities that DHS discovered in 2016. And Boeing claims the attacks don’t work.

Bypassing Apple FaceID's Liveness Detection Feature

Apple’s FaceID has a liveness detection feature, which prevents someone from unlocking a victim’s phone by putting it in front of his face while he’s sleeping. That feature has been hacked:

Researchers on Wednesday during Black Hat USA 2019 demonstrated an attack that allowed them to bypass a victim’s FaceID and log into their phone simply by putting a pair of modified glasses on their face. By merely placing tape carefully over the lenses of a pair glasses and placing them on the victim’s face the researchers demonstrated how they could bypass Apple’s FaceID in a specific scenario. The attack itself is difficult, given the bad actor would need to figure out how to put the glasses on an unconscious victim without waking them up.

AT&T Employees Took Bribes to Unlock Smartphones

This wasn’t a small operation:

A Pakistani man bribed AT&T call-center employees to install malware and unauthorized hardware as part of a scheme to fraudulently unlock cell phones, according to the US Department of Justice. Muhammad Fahd, 34, was extradited from Hong Kong to the US on Friday and is being detained pending trial.

An indictment alleges that “Fahd recruited and paid AT&T insiders to use their computer credentials and access to disable AT&T’s proprietary locking software that prevented ineligible phones from being removed from AT&T’s network,” a DOJ announcement yesterday said. “The scheme resulted in millions of phones being removed from AT&T service and/or payment plans, costing the company millions of dollars. Fahd allegedly paid the insiders hundreds of thousands of dollars­—paying one co-conspirator $428,500 over the five-year scheme.”

In all, AT&T insiders received more than $1 million in bribes from Fahd and his co-conspirators, who fraudulently unlocked more than 2 million cell phones, the government alleged. Three former AT&T customer service reps from a call center in Bothell, Washington, already pleaded guilty and agreed to pay the money back to AT&T.

Brazilian Cell Phone Hack

I know there’s a lot of politics associated with this story, but concentrate on the cybersecurity aspect for a moment. The cell phones of a thousand Brazilians, including senior government officials, were hacked—seemingly by actors much less sophisticated than rival governments.

Brazil’s federal police arrested four people for allegedly hacking 1,000 cellphones belonging to various government officials, including that of President Jair Bolsonaro.

Police detective João Vianey Xavier Filho said the group hacked into the messaging apps of around 1,000 different cellphone numbers, but provided little additional information at a news conference in Brasilia on Wednesday. Cellphones used by Bolsonaro were among those attacked by the group, the justice ministry said in a statement on Thursday, adding that the president was informed of the security breach.

[…]

In the court order determining the arrest of the four suspects, Judge Vallisney de Souza Oliveira wrote that the hackers had accessed Moro’s Telegram messaging app, along with those of two judges and two federal police officers.

When I say that smartphone security equals national security, this is the kind of thing I am talking about.

Insider Logic Bombs

Add to the “not very smart criminals” file:

According to court documents, Tinley provided software services for Siemens’ Monroeville, PA offices for nearly ten years. Among the work he was asked to perform was the creation of spreadsheets that the company was using to manage equipment orders.

The spreadsheets included custom scripts that would update the content of the file based on current orders stored in other, remote documents, allowing the company to automate inventory and order management.

But while Tinley’s files worked for years, they started malfunctioning around 2014. According to court documents, Tinley planted so-called “logic bombs” that would trigger after a certain date, and crash the files.

Every time the scripts would crash, Siemens would call Tinley, who’d fix the files for a fee.

Hackers Expose Russian FSB Cyberattack Projects

More nation-state activity in cyberspace, this time from Russia:

Per the different reports in Russian media, the files indicate that SyTech had worked since 2009 on a multitude of projects since 2009 for FSB unit 71330 and for fellow contractor Quantum. Projects include:

  • Nautilus—a project for collecting data about social media users (such as Facebook, MySpace, and LinkedIn).
  • Nautilus-S—a project for deanonymizing Tor traffic with the help of rogue Tor servers.
  • Reward—a project to covertly penetrate P2P networks, like the one used for torrents.
  • Mentor—a project to monitor and search email communications on the servers of Russian companies.
  • Hope—a project to investigate the topology of the Russian internet and how it connects to other countries’ network.
  • Tax-3—a project for the creation of a closed intranet to store the information of highly-sensitive state figures, judges, and local administration officials, separate from the rest of the state’s IT networks.

BBC Russia, who received the full trove of documents, claims there were other older projects for researching other network protocols such as Jabber (instant messaging), ED2K (eDonkey), and OpenFT (enterprise file transfer).

Other files posted on the Digital Revolution Twitter account claimed that the FSB was also tracking students and pensioners.

Details of the Cloud Hopper Attacks

Reuters has a long article on the Chinese government APT attack called Cloud Hopper. It was much bigger than originally reported.

The hacking campaign, known as “Cloud Hopper,” was the subject of a U.S. indictment in December that accused two Chinese nationals of identity theft and fraud. Prosecutors described an elaborate operation that victimized multiple Western companies but stopped short of naming them. A Reuters report at the time identified two: Hewlett Packard Enterprise and IBM.

Yet the campaign ensnared at least six more major technology firms, touching five of the world’s 10 biggest tech service providers.

Also compromised by Cloud Hopper, Reuters has found: Fujitsu, Tata Consultancy Services, NTT Data, Dimension Data, Computer Sciences Corporation and DXC Technology. HPE spun-off its services arm in a merger with Computer Sciences Corporation in 2017 to create DXC.

Waves of hacking victims emanate from those six plus HPE and IBM: their clients. Ericsson, which competes with Chinese firms in the strategically critical mobile telecoms business, is one. Others include travel reservation system Sabre, the American leader in managing plane bookings, and the largest shipbuilder for the U.S. Navy, Huntington Ingalls Industries, which builds America’s nuclear submarines at a Virginia shipyard.

Cell Networks Hacked by (Probable) Nation-State Attackers

A sophisticated attacker has successfuly infiltrated cell providers to collect information on specific users:

The hackers have systematically broken in to more than 10 cell networks around the world to date over the past seven years to obtain massive amounts of call records—including times and dates of calls, and their cell-based locations—on at least 20 individuals.

[…]

Cybereason researchers said they first detected the attacks about a year ago. Before and since then, the hackers broke into one cell provider after the other to gain continued and persistent access to the networks. Their goal, the researchers believe, is to obtain and download rolling records on the target from the cell provider’s database without having to deploy malware on each target’s device.

[…]

The researchers found the hackers got into one of the cell networks by exploiting a vulnerability on an internet-connected web server to gain a foothold onto the provider’s internal network. From there, the hackers continued to exploit each machine they found by stealing credentials to gain deeper access.

Who did it?

Cybereason did say it was with “very high probability” that the hackers were backed by a nation state but the researchers were reluctant to definitively pin the blame.

The tools and the techniques ­- such as the malware used by the hackers ­- appeared to be “textbook APT 10,” referring to a hacker group believed to be backed by China, but Div said it was either APT 10, “or someone that wants us to go public and say it’s [APT 10].”

Original report:

Based on the data available to us, Operation Soft Cell has been active since at least 2012, though some evidence suggests even earlier activity by the threat actor against telecommunications providers.

The attack was aiming to obtain CDR records of a large telecommunications provider.

The threat actor was attempting to steal all data stored in the active directory, compromising every single username and password in the organization, along with other personally identifiable information, billing data, call detail records, credentials, email servers, geo-location of users, and more.

The tools and TTPs used are commonly associated with Chinese threat actors.

During the persistent attack, the attackers worked in waves—abandoning one thread of attack when it was detected and stopped, only to return months later with new tools and techniques.

Boing Boing post.
