Stolen Bitcoins Returned

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/stolen-bitcoins-returned.html

The US has returned $154 million in bitcoins stolen by a Sony employee.

However, on December 1, following an investigation in collaboration with Japanese law enforcement authorities, the FBI seized the 3879.16242937 BTC in Ishii’s wallet after obtaining the private key, which made it possible to transfer all the bitcoins to the FBI’s bitcoin wallet.

More on NSO Group and Cytrox: Two Cyberweapons Arms Manufacturers

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/more-on-nso-group-and-cytrox-two-cyberweapons-arms-manufacturers.html

Citizen Lab published another report on the spyware used against two Egyptian nationals. One was hacked by NSO Group’s Pegasus spyware. The other was hacked both by Pegasus and by the spyware from another cyberweapons arms manufacturer: Cytrox.

We haven’t heard a lot about Cytrox and its Predator spyware. According to Citzen Lab:

We conducted Internet scanning for Predator spyware servers and found likely Predator customers in Armenia, Egypt, Greece, Indonesia, Madagascar, Oman, Saudi Arabia, and Serbia.

Cytrox was reported to be part of Intellexa, the so-called “Star Alliance of spyware,” which was formed to compete with NSO Group, and which describes itself as “EU-based and regulated, with six sites and R&D labs throughout Europe.”

In related news, Google’s Project Zero has published a detailed analysis of NSO Group’s zero-click iMessage exploit: FORCED ENTRY.

Based on our research and findings, we assess this to be one of the most technically sophisticated exploits we’ve ever seen, further demonstrating that the capabilities NSO provides rival those previously thought to be accessible to only a handful of nation states.

By the way, this vulnerability was patched on 13 Sep 2021 in iOS 14.8.

Friday Squid Blogging: UK Recognizes Squid as Sentient Beings

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/friday-squid-blogging-uk-recognizes-squid-as-sentient-beings.html

This seems big:

The UK government has officially included decapod crustaceans–including crabs, lobsters, and crayfish–and cephalopod mollusks–including octopuses, squid, and cuttlefish–in its Animal Welfare (Sentience) Bill. This means they are now recognized as “sentient beings” in the UK.

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

More Log4j News

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/more-log4j-news.html

Log4j is being exploited by all sorts of attackers, all over the Internet:

At that point it was reported that there were over 100 attempts to exploit the vulnerability every minute. “Since we started to implement our protection we prevented over 1,272,000 attempts to allocate the vulnerability, over 46% of those attempts were made by known malicious groups,” said cybersecurity company Check Point.

And according to Check Point, attackers have now attempted to exploit the flaw on over 40% of global networks.

And a second vulnerability was found, in the patch for the first vulnerability. This is likely not to be the last.

On the Log4j Vulnerability

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/on-the-log4j-vulnerability.html

It’s serious:

The range of impacts is so broad because of the nature of the vulnerability itself. Developers use logging frameworks to keep track of what happens in a given application. To exploit Log4Shell, an attacker only needs to get the system to log a strategically crafted string of code. From there they can load arbitrary code on the targeted server and install malware or launch other attacks. Notably, hackers can introduce the snippet in seemingly benign ways, like by sending the string in an email or setting it as an account username.

Threat advisory from Cisco. Cloudflare found it in the wild before it was disclosed. CISA is very concerned, saying that hundreds of millions of devices are likely affected.

NSO Group’s Pegasus Spyware Used Against US State Department Officials

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/nso-groups-pegasus-spyware-used-against-us-state-department-officials.html

NSO Group’s descent into Internet pariah status continues. Its Pegasus spyware was used against nine US State Department employees. We don’t know which NSO Group customer trained the spyware on the US. But the company does:

NSO Group said in a statement on Thursday that it did not have any indication their tools were used but canceled access for the relevant customers and would investigate based on the Reuters inquiry.

“If our investigation shall show these actions indeed happened with NSO’s tools, such customer will be terminated permanently and legal actions will take place,” said an NSO spokesperson, who added that NSO will also “cooperate with any relevant government authority and present the full information we will have.”

Google Shuts Down Glupteba Botnet, Sues Operators

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/google-shuts-down-glupteba-botnet-sues-operators.html

Google took steps to shut down the Glupteba botnet, at least for now. (The botnet uses the bitcoin blockchain as a backup command-and-control mechanism, making it hard to get rid of it permanently.) So Google is also suing the botnet’s operators.

It’s an interesting strategy. Let’s see if it’s successful.

New German Government is Pro-Encryption and Anti-Backdoors

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/new-german-government-is-pro-encryption-and-anti-backdoors.html

I hope this is true:

According to Jens Zimmermann, the German coalition negotiations had made it “quite clear” that the incoming government of the Social Democrats (SPD), the Greens and the business-friendly liberal FDP would reject “the weakening of encryption, which is being attempted under the guise of the fight against child abuse” by the coalition partners.

Such regulations, which are already enshrined in the interim solution of the ePrivacy Regulation, for example, “diametrically contradict the character of the coalition agreement” because secure end-to-end encryption is guaranteed there, Zimmermann said.

Introducing backdoors would undermine this goal of the coalition agreement, he added.

I have written about this.

Someone Is Running Lots of Tor Relays

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/someone-is-running-lots-of-tor-relays.html

Since 2017, someone is running about a thousand — 10% of the total — Tor servers in an attempt to deanonymize the network:

Grouping these servers under the KAX17 umbrella, Nusenu says this threat actor has constantly added servers with no contact details to the Tor network in industrial quantities, operating servers in the realm of hundreds at any given point.

The actor’s servers are typically located in data centers spread all over the world and are typically configured as entry and middle points primarily, although KAX17 also operates a small number of exit points.

Nusenu said this is strange as most threat actors operating malicious Tor relays tend to focus on running exit points, which allows them to modify the user’s traffic. For example, a threat actor that Nusenu has been tracking as BTCMITM20 ran thousands of malicious Tor exit nodes in order to replace Bitcoin wallet addresses inside web traffic and hijack user payments.

KAX17’s focus on Tor entry and middle relays led Nusenu to believe that the group, which he described as “non-amateur level and persistent,” is trying to collect information on users connecting to the Tor network and attempting to map their routes inside it.

In research published this week and shared with The Record, Nusenu said that at one point, there was a 16% chance that a Tor user would connect to the Tor network through one of KAX17’s servers, a 35% chance they would pass through one of its middle relays, and up to 5% chance to exit through one.

Thieves Using AirTags to “Follow” Cars

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/thieves-using-airtags-to-follow-cars.html

From Ontario and not surprising:

Since September 2021, officers have investigated five incidents where suspects have placed small tracking devices on high-end vehicles so they can later locate and steal them. Brand name “air tags” are placed in out-of-sight areas of the target vehicles when they are parked in public places like malls or parking lots. Thieves then track the targeted vehicles to the victim’s residence, where they are stolen from the driveway.

Thieves typically use tools like screwdrivers to enter the vehicles through the driver or passenger door, while ensuring not to set off alarms. Once inside, an electronic device, typically used by mechanics to reprogram the factory setting, is connected to the onboard diagnostics port below the dashboard and programs the vehicle to accept a key the thieves have brought with them. Once the new key is programmed, the vehicle will start and the thieves drive it away.

I’m not sure if there’s anything that can be done:

When Apple first released AirTags earlier this year, concerns immediately sprung up about nefarious use cases for the covert trackers. Apple responded with a slew of anti-stalking measures, but those are more intended for keeping people safe than cars. An AirTag away from its owner will sound an alarm, letting anyone nearby know that it’s been left behind, but it can take up to 24 hours for that alarm to go off — more than enough time to nab a car in the dead of night.

Testing Faraday Cages

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/testing-faraday-cages.html

Matt Blaze tested a variety of Faraday cages for phones, both commercial and homemade.

The bottom line:

A quick and likely reliable “go/no go test” can be done with an Apple AirTag and an iPhone: drop the AirTag in the bag under test, and see if the phone can locate it and activate its alarm (beware of caching in the FindMy app when doing this).

This test won’t tell you the exact attenuation level, of course, but it will tell you if the attenuation is sufficient for most practical purposes. It can also detect whether an otherwise good bag has been damaged and compromised.

At least in the frequency ranges I tested, two commercial Faraday pouches (the EDEC OffGrid and Mission Darkness Window pouches) yielded excellent performance sufficient to provide assurance of signal isolation under most real-world circumstances. None of the makeshift solutions consistently did nearly as well, although aluminum foil can, under ideal circumstances (that are difficult to replicate) sometimes provide comparable levels of attenuation.

Smart Contract Bug Results in $31 Million Loss

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/12/smart-contract-bug-results-in-31-million-loss.html

A hacker stole $31 million from the blockchain company MonoX Finance , by exploiting a bug in software the service uses to draft smart contracts.

Specifically, the hack used the same token as both the tokenIn and tokenOut, which are methods for exchanging the value of one token for another. MonoX updates prices after each swap by calculating new prices for both tokens. When the swap is completed, the price of tokenIn­that is, the token sent by the user­decreases and the price of tokenOut­or the token received by the user­increases.

By using the same token for both tokenIn and tokenOut, the hacker greatly inflated the price of the MONO token because the updating of the tokenOut overwrote the price update of the tokenIn. The hacker then exchanged the token for $31 million worth of tokens on the Ethereum and Polygon blockchains.

The article goes on to talk about how common these sorts of attacks are. The basic problem is that the code is the ultimate authority — there is no adjudication protocol — so if there’s a vulnerability in the code, there is no recourse. And, of course, there are lots of vulnerabilities in code.

To me, this is reason enough never to use smart contracts for anything important. Human-based adjudication systems are not useless pre-Internet human baggage, they’re vital.

Intel Is Maintaining Legacy Technology for Security Research

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/11/intel-is-maintaining-legacy-technology-for-security-research.html

Interesting:

Intel’s issue reflects a wider concern: Legacy technology can introduce cybersecurity weaknesses. Tech makers constantly improve their products to take advantage of speed and power increases, but customers don’t always upgrade at the same pace. This creates a long tail of old products that remain in widespread use, vulnerable to attacks.

Intel’s answer to this conundrum was to create a warehouse and laboratory in Costa Rica, where the company already had a research-and-development lab, to store the breadth of its technology and make the devices available for remote testing. After planning began in mid-2018, the Long-Term Retention Lab was up and running in the second half of 2019.

The warehouse stores around 3,000 pieces of hardware and software, going back about a decade. Intel plans to expand next year, nearly doubling the space to 27,000 square feet from 14,000, allowing the facility to house 6,000 pieces of computer equipment.

Intel engineers can request a specific machine in a configuration of their choice. It is then assembled by a technician and accessible through cloud services. The lab runs 24 hours a day, seven days a week, typically with about 25 engineers working any given shift.

Apple Sues NSO Group

Post Syndicated from Bruce Schneier original https://www.schneier.com/blog/archives/2021/11/apple-sues-nso-group.html

Piling more on NSO Group’s legal troubles, Apple is suing it:

The complaint provides new information on how NSO Group infected victims’ devices with its Pegasus spyware. To prevent further abuse and harm to its users, Apple is also seeking a permanent injunction to ban NSO Group from using any Apple software, services, or devices.

NSO Group’s Pegasus spyware is favored by totalitarian governments around the world, who use it to hack Apple phones and computers.

More news:

Apple’s legal complaint provides new information on NSO Group’s FORCEDENTRY, an exploit for a now-patched vulnerability previously used to break into a victim’s Apple device and install the latest version of NSO Group’s spyware product, Pegasus. The exploit was originally identified by the Citizen Lab, a research group at the University of Toronto.

The spyware was used to attack a small number of Apple users worldwide with dangerous malware and spyware. Apple’s lawsuit seeks to ban NSO Group from further harming individuals by using Apple’s products and services. The lawsuit also seeks redress for NSO Group’s flagrant violations of US federal and state law, arising out of its efforts to target and attack Apple and its users.

NSO Group and its clients devote the immense resources and capabilities of nation-states to conduct highly targeted cyberattacks, allowing them to access the microphone, camera, and other sensitive data on Apple and Android devices. To deliver FORCEDENTRY to Apple devices, attackers created Apple IDs to send malicious data to a victim’s device — allowing NSO Group or its clients to deliver and install Pegasus spyware without a victim’s knowledge. Though misused to deliver FORCEDENTRY, Apple servers were not hacked or compromised in the attacks.

This follows in the footsteps of Facebook, which is also suing NSO Group and demanding a similar prohibition. And while the idea of the intermediary suing the attacker, and not the victim, is somewhat novel, I think it makes a lot of sense. I have a law journal article about to be published with Jon Penney on the Facebook case.
