Australia is reporting that a BlackBerry device has been cracked after five years:
An encrypted BlackBerry device that was cracked five years after it was first seized by police is poised to be the key piece of evidence in one of the state’s longest-running drug importation investigations.
In April, new technology “capabilities” allowed authorities to probe the encrypted device….
No details about those capabilities.

Makes sense; there’s room inside a squid’s body cavity:
Latin American drug lords have sent bumper shipments of cocaine to Europe in recent weeks, including one in a cargo of squid, even though the coronavirus epidemic has stifled legitimate transatlantic trade, senior anti-narcotics officials say.
As usual, you can also use this squid post to talk about the security stories in the news that I haven’t covered.

German investigators said Friday they have shut down a data processing center installed in a former NATO bunker that hosted sites dealing in drugs and other illegal activities. Seven people were arrested.
Thirteen people aged 20 to 59 are under investigation in all, including three German and seven Dutch citizens, Brauer said.
Authorities arrested seven of them, citing the danger of flight and collusion. They are suspected of membership in a criminal organization because of a tax offense, as well as being accessories to hundreds of thousands of offenses involving drugs, counterfeit money and forged documents, and accessories to the distribution of child pornography. Authorities didn’t name any of the suspects.
The data center was set up as what investigators described as a “bulletproof hoster,” meant to conceal illicit activities from authorities’ eyes.
Investigators say the platforms it hosted included “Cannabis Road,” a drug-dealing portal; the “Wall Street Market,” which was one of the world’s largest online criminal marketplaces for drugs, hacking tools and financial-theft wares until it was taken down earlier this year; and sites such as “Orange Chemicals” that dealt in synthetic drugs. A botnet attack on German telecommunications company Deutsche Telekom in late 2016 that knocked out about 1 million customers’ routers also appears to have come from the data center in Traben-Trarbach, Brauer said.

Impressive police work:
In a daring move that placed his life in danger, the I.T. consultant eventually gave the F.B.I. his system’s secret encryption keys in 2011 after he had moved the network’s servers from Canada to the Netherlands during what he told the cartel’s leaders was a routine upgrade.
A Dutch article says that it’s a BlackBerry system.
El Chapo had his IT person install “…spyware called FlexiSPY on the ‘special phones’ he had given to his wife, Emma Coronel Aispuro, as well as to two of his lovers, including one who was a former Mexican lawmaker.” That same software was used by the FBI when his IT person turned over the keys. Yet again we learn the lesson that a backdoor can be used against you.
And it doesn’t have to be with the IT person’s permission. A good intelligence agency can use the IT person’s authorizations without his knowledge or consent. This is why the NSA hunts sysadmins.

New research: “Leaving on a jet plane: the trade in fraudulently obtained airline tickets:”
Abstract: Every day, hundreds of people fly on airline tickets that have been obtained fraudulently. This crime script analysis provides an overview of the trade in these tickets, drawing on interviews with industry and law enforcement, and an analysis of an online blackmarket. Tickets are purchased by complicit travellers or resellers from the online blackmarket. Victim travellers obtain tickets from fake travel agencies or malicious insiders. Compromised credit cards used to be the main method to purchase tickets illegitimately. However, as fraud detection systems improved, offenders displaced to other methods, including compromised loyalty point accounts, phishing, and compromised business accounts. In addition to complicit and victim travellers, fraudulently obtained tickets are used for transporting mules, and for trafficking and smuggling. This research details current prevention approaches, and identifies additional interventions, aimed at the act, the actor, and the marketplace.

Police in the UK were able to read a fingerprint from a photo of a hand:
Staff from the unit’s specialist imaging team were able to enhance a picture of a hand holding a number of tablets, which was taken from a mobile phone, before fingerprint experts were able to positively identify that the hand was that of Elliott Morris.
Speaking about the pioneering techniques used in the case, Dave Thomas, forensic operations manager at the Scientific Support Unit, added: “Specialist staff within the JSIU fully utilised their expert image-enhancing skills which enabled them to provide something that the unit’s fingerprint identification experts could work. Despite being provided with only a very small section of the fingerprint which was visible in the photograph, the team were able to successfully identify the individual.”

News from Australia:
Under the law, internet companies would have the same obligations telephone companies do to help law enforcement agencies, Prime Minister Malcolm Turnbull said. Law enforcement agencies would need warrants to access the communications.
“We’ve got a real problem in that the law enforcement agencies are increasingly unable to find out what terrorists and drug traffickers and pedophile rings are up to because of the very high levels of encryption,” Turnbull told reporters.
“Where we can compel it, we will, but we will need the cooperation from the tech companies,” he added.
Never mind that the law 1) would not achieve the desired results because all the smart “terrorists and drug traffickers and pedophile rings” will simply use a third-party encryption app, and 2) would make everyone else in Australia less secure. But that’s all ground I’ve covered before.
I found this bit amusing:
Asked whether the laws of mathematics behind encryption would trump any new legislation, Mr Turnbull said: “The laws of Australia prevail in Australia, I can assure you of that.
“The laws of mathematics are very commendable but the only law that applies in Australia is the law of Australia.”
Next Turnbull is going to try to legislate that pi = 3.2.

I saw two related stories today. The first is about high-denomination currency. The EU is considering dropping its 500-euro note, on the grounds that only criminals need to move around that much cash. In response, Switzerland said that it is not dropping its 1,000-Swiss franc note. Of course, the US leads the way in small money here; its biggest banknote is $100.
This probably matters. Moving and laundering cash is at least as big a logistical and legal problem as moving and selling drugs. On the other hand, countries make a profit from their cash in circulation: it’s called seigniorage.
The second story is about the risks associated with legal marijuana dispensaries in the US not being able to write checks, have a bank account, and so on. There’s the physical risk of theft and violence, and the logistical nightmare of having to pay a $100K tax bill with marijuana-smelling paper currency.

I’ve already written about Sean Penn’s opsec while communicating with El Chapo. Here’s the technique of mirroring, explained:
El chapo then switched to a complex system of using BBM (Blackberry’s Instant Messaging) and Proxies. The way it worked was if you needed to contact The Boss, you would send a BBM text to an intermediary (who would spend his days at a public place with Wi-Fi) this intermediary (or “mirror”) would then transcribe the text to an I-Pad and then send that over a Wi-Fi network (not cellular networks which were monitored constantly by law enforcement). This WiFi text was then sent to another cut-out who would finally transcribe the message into a Blackberry BBM text and transmit it to Guzman. Although Guzman continued to use his Blackberry, it was almost impossible to analyze the traffic because it now only communicated with one other device. This “mirror” system is difficult to crack because the intermediaries or proxies, can constantly change their location by moving to new WiFi spots.
This article claims he was caught because of a large food order:
After construction was complete, the safehouse was quiet. Until 7 January 2016, when a car arrives carrying unknown passengers. Security forces suspected that this was Guzman. There was one final indicator that someone important enough to require an entourage was inside. A white van went off, at midnight, to fetch enough tacos to feed a large group of people. The police raided the house 4 hours later.
Here’s more detail about El Chapo’s opsec at the time of his previous capture.

This article talks about the opsec used by Sean Penn surrounding his meeting with El Chapo.
Security experts say there aren’t enough public details to fully analyze Penn’s operational security (opsec). But they described the paragraph above as “incomprehensible” and “gibberish.” Let’s try to break it down:
- Penn describes using “TracPhones,” by which he likely means TracFones, which are cheap phones that take calling cards so they’re not linked to a credit card or account. They’re often called burners, but you don’t actually throw it in the trash after a call; instead you might swap out the SIM card or use different calling cards for different people. Hollywood loves these! Katie Holmes reportedly used one to plan her divorce from Tom Cruise. They’re a reasonable security measure, but it still creates phone records that live with, and can be requested from, cell phone carriers.
- Penn says he “mirror[ed] through Blackphones,” which are relatively expensive phones sold by Silent Circle that offer a more secure operating system than a typical off-the-shelf phone. It runs Internet through a VPN (to shield the user’s IP address and encrypt their Web traffic) and end-to-end encrypts calls and messages sent to other Blackphones. Unlike with the TracFone, Penn would have a credit card tied to the account on this phone. It’s unclear what Penn means when he says he “mirrored” through the phone; the phrase “mirrored” typically means to duplicate something. As he wrote it, it sounds like he duplicated messages on the secure Blackphone that were being sent some other, potentially less secure, way, which would be dumb, if true. “I’m not sure what he means.” said Silent Circle CEO Mike Janke via email. “It’s a strange term and most likely he doesn’t know what he is saying.”
- Penn says he used “anonymous” email addresses and that he and his companions accessed messages left as drafts in a shared email account. That likely means the emails were stored unencrypted, a bad security practice. If he were sharing the account with a person using an IP address that was the target of an investigation, i.e. any IP address associated with El Chapo’s crew, then all messages shared this way would be monitored. For the record, that did not work out very well for former CIA director David Petraeus, who used draft messages to communicate with his mistress and got busted when her IP address was targeted in an online harassment investigation.
- Elsewhere in the article, Penn says Guzman corresponded with Mexican actress Kate del Castillo via BBMs (Blackberry messages). Those only have unique end-to-end encryption if a user has opted for BBM Protected. Law enforcement has been able to intercept BBMs in the past. And Mexican officials have told the media that they were monitoring del Castillo for months, following a meeting she had last summer with El Chapo’s lawyers, before she had reached out to Penn. Law enforcement even reportedly got photos of Penn’s arrival at the airport in Mexico.
- In the most impressive operational, if not personal, security on display, Sean Penn says that when he traveled to Mexico, he left all of his electronics in Los Angeles, knowing that El Chapo’s crew would force him to leave them behind.
There has been lots of speculation about whether this was enough, or whether Mexican officials tracked El Chapo down because of his meeting with Penn.
