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.
French police hacked EncroChat secure phones, which are widely used by criminals:
Encrochat’s phones are essentially modified Android devices, with some models using the “BQ Aquaris X2,” an Android handset released in 2018 by a Spanish electronics company, according to the leaked documents. Encrochat took the base unit, installed its own encrypted messaging programs which route messages through the firm’s own servers, and even physically removed the GPS, camera, and microphone functionality from the phone. Encrochat’s phones also had a feature that would quickly wipe the device if the user entered a PIN, and ran two operating systems side-by-side. If a user wanted the device to appear innocuous, they booted into normal Android. If they wanted to return to their sensitive chats, they switched over to the Encrochat system. The company sold the phones on a subscription based model, costing thousands of dollars a year per device.
This allowed them and others to investigate and arrest many:
Unbeknownst to Mark, or the tens of thousands of other alleged Encrochat users, their messages weren’t really secure. French authorities had penetrated the Encrochat network, leveraged that access to install a technical tool in what appears to be a mass hacking operation, and had been quietly reading the users’ communications for months. Investigators then shared those messages with agencies around Europe.
Only now is the astonishing scale of the operation coming into focus: It represents one of the largest law enforcement infiltrations of a communications network predominantly used by criminals ever, with Encrochat users spreading beyond Europe to the Middle East and elsewhere. French, Dutch, and other European agencies monitored and investigated “more than a hundred million encrypted messages” sent between Encrochat users in real time, leading to arrests in the UK, Norway, Sweden, France, and the Netherlands, a team of international law enforcement agencies announced Thursday.
EncroChat learned about the hack, but didn’t know who was behind it.
Going into full-on emergency mode, Encrochat sent a message to its users informing them of the ongoing attack. The company also informed its SIM provider, Dutch telecommunications firm KPN, which then blocked connections to the malicious servers, the associate claimed. Encrochat cut its own SIM service; it had an update scheduled to push to the phones, but it couldn’t guarantee whether that update itself wouldn’t be carrying malware too. That, and maybe KPN was working with the authorities, Encrochat’s statement suggested (KPN declined to comment). Shortly after Encrochat restored SIM service, KPN removed the firewall, allowing the hackers’ servers to communicate with the phones once again. Encrochat was trapped.
Encrochat decided to shut itself down entirely.
Lots of details about the hack in the article. Well worth reading in full.
The UK National Crime Agency called it Operation Venetic: “46 arrests, and £54m criminal cash, 77 firearms and over two tonnes of drugs seized so far.”
EDITED TO ADD (7/14): Some people are questioning the official story. I don’t know.
I was wondering about this:
Masks that have made criminals stand apart long before bandanna-wearing robbers knocked over stagecoaches in the Old West and ski-masked bandits held up banks now allow them to blend in like concerned accountants, nurses and store clerks trying to avoid a deadly virus.
“Criminals, they’re smart and this is a perfect opportunity for them to conceal themselves and blend right in,” said Richard Bell, police chief in the tiny Pennsylvania community of Frackville. He said he knows of seven recent armed robberies in the region where every suspect wore a mask.
Just how many criminals are taking advantage of the pandemic to commit crimes is impossible to estimate, but law enforcement officials have no doubt the numbers are climbing. Reports are starting to pop up across the United States and in other parts of the world of crimes pulled off in no small part because so many of us are now wearing masks.
In March, two men walked into Aqueduct Racetrack in New York wearing the same kind of surgical masks as many racing fans there and, at gunpoint, robbed three workers of a quarter-million dollars they were moving from gaming machines to a safe. Other robberies involving suspects wearing surgical masks have occurred in North Carolina, and Washington, D.C, and elsewhere in recent weeks.
The article is all anecdote and no real data. But this is probably a trend.
This is interesting:
Facebook Inc. in 2018 beat back federal prosecutors seeking to wiretap its encrypted Messenger app. Now the American Civil Liberties Union is seeking to find out how.
The entire proceeding was confidential, with only the result leaking to the press. Lawyers for the ACLU and the Washington Post on Tuesday asked a San Francisco-based federal court of appeals to unseal the judge’s decision, arguing the public has a right to know how the law is being applied, particularly in the area of privacy.
The Facebook case stems from a federal investigation of members of the violent MS-13 criminal gang. Prosecutors tried to hold Facebook in contempt after the company refused to help investigators wiretap its Messenger app, but the judge ruled against them. If the decision is unsealed, other tech companies will likely try to use its reasoning to ward off similar government requests in the future.
A federal court has ruled that violating a website’s terms of service is not “hacking” under the Computer Fraud and Abuse Act.
The plaintiffs wanted to investigate possible racial discrimination in online job markets by creating accounts for fake employers and job seekers. Leading job sites have terms of service prohibiting users from supplying fake information, and the researchers worried that their research could expose them to criminal liability under the CFAA, which makes it a crime to “access a computer without authorization or exceed authorized access.”
So in 2016 they sued the federal government, seeking a declaration that this part of the CFAA violated the First Amendment.
But rather than addressing that constitutional issue, Judge John Bates ruled on Friday that the plaintiffs’ proposed research wouldn’t violate the CFAA’s criminal provisions at all. Someone violates the CFAA when they bypass an access restriction like a password. But someone who logs into a website with a valid password doesn’t become a hacker simply by doing something prohibited by a website’s terms of service, the judge concluded.
“Criminalizing terms-of-service violations risks turning each website into its own criminal jurisdiction and each webmaster into his own legislature,” Bates wrote.
Bates noted that website terms of service are often long, complex, and change frequently. While some websites require a user to read through the terms and explicitly agree to them, others merely include a link to the terms somewhere on the page. As a result, most users aren’t even aware of the contractual terms that supposedly govern the site. Under those circumstances, it’s not reasonable to make violation of such terms a criminal offense, Bates concluded.
This is not the first time a court has issued a ruling in this direction. It’s also not the only way the courts have interpreted the frustratingly vague Computer Fraud and Abuse Act.
EDITED TO ADD (4/13): The actual opinion.
This isn’t a first, but I think it will be the first conviction:
The GIF set off a highly unusual court battle that is expected to equip those in similar circumstances with a new tool for battling threatening trolls and cyberbullies. On Monday, the man who sent Eichenwald the moving image, John Rayne Rivello, was set to appear in a Dallas County district court. A last-minute rescheduling delayed the proceeding until Jan. 31, but Rivello is still expected to plead guilty to aggravated assault. And he may be the first of many.
The Epilepsy Foundation announced on Monday it lodged a sweeping slate of criminal complaints against a legion of copycats who targeted people with epilepsy and sent them an onslaught of strobe GIFs — a frightening phenomenon that unfolded in a short period of time during the organization’s marking of National Epilepsy Awareness Month in November.
Rivello’s supporters — among them, neo-Nazis and white nationalists, including Richard Spencer — have also argued that the issue is about freedom of speech. But in an amicus brief to the criminal case, the First Amendment Clinic at Duke University School of Law argued Rivello’s actions were not constitutionally protected.
“A brawler who tattoos a message onto his knuckles does not throw every punch with the weight of First Amendment protection behind him,” the brief stated. “Conduct like this does not constitute speech, nor should it. A deliberate attempt to cause physical injury to someone does not come close to the expression which the First Amendment is designed to protect.”
EDITED TO ADD (1/14): There was a similar case in Germany in 2012 — that attacker was convicted.
Back in 1998, Tim May warned us of the “Four Horsemen of the Infocalypse”: “terrorists, pedophiles, drug dealers, and money launderers.” I tended to cast it slightly differently. This is me from 2005:
Beware the Four Horsemen of the Information Apocalypse: terrorists, drug dealers, kidnappers, and child pornographers. Seems like you can scare any public into allowing the government to do anything with those four.
Which particular horseman is in vogue depends on time and circumstance. Since the terrorist attacks of 9/11, the US government has been pushing the terrorist scare story. Recently, it seems to have switched to pedophiles and child exploitation. It began in September, with a long New York Times story on child sex abuse, which included this dig at encryption:
And when tech companies cooperate fully, encryption and anonymization can create digital hiding places for perpetrators. Facebook announced in March plans to encrypt Messenger, which last year was responsible for nearly 12 million of the 18.4 million worldwide reports of child sexual abuse material, according to people familiar with the reports. Reports to the authorities typically contain more than one image, and last year encompassed the record 45 million photos and videos, according to the National Center for Missing and Exploited Children.
That was followed up by a conference by the US Department of Justice: “Lawless Spaces: Warrant Proof Encryption and its Impact on Child Exploitation Cases.” US Attorney General William Barr gave a speech on the subject. Then came an open letter to Facebook from Barr and others from the UK and Australia, using “protecting children” as the basis for their demand that the company not implement strong end-to-end encryption. (I signed on to another another open letter in response.) Then, the FBI tried to get Interpol to publish a statement denouncing end-to-end encryption.
This week, the Senate Judiciary Committee held a hearing on backdoors: “Encryption and Lawful Access: Evaluating Benefits and Risks to Public Safety and Privacy.” Video, and written testimonies, are available at the link. Eric Neuenschwander from Apple was there to support strong encryption, but the other witnesses were all against it. New York District Attorney Cyrus Vance was true to form:
In fact, we were never able to view the contents of his phone because of this gift to sex traffickers that came, not from God, but from Apple.
It was a disturbing hearing. The Senators asked technical questions to people who couldn’t answer them. The result was that an adjunct law professor was able to frame the issue of strong encryption as an externality caused by corporate liability dumping, and another example of Silicon Valley’s anti-regulation stance.
Let me be clear. None of us who favor strong encryption is saying that child exploitation isn’t a serious crime, or a worldwide problem. We’re not saying that about kidnapping, international drug cartels, money laundering, or terrorism. We are saying three things. One, that strong encryption is necessary for personal and national security. Two, that weakening encryption does more harm than good. And three, law enforcement has other avenues for criminal investigation than eavesdropping on communications and stored devices. This is one example, where people unraveled a dark-web website and arrested hundreds by analyzing Bitcoin transactions. This is another, where policy arrested members of a WhatsApp group.
So let’s have reasoned policy debates about encryption — debates that are informed by technology. And let’s stop it with the scare stories.
EDITED TO ADD (12/13): The DoD just said that strong encryption is essential for national security.
All DoD issued unclassified mobile devices are required to be password protected using strong passwords. The Department also requires that data-in-transit, on DoD issued mobile devices, be encrypted (e.g. VPN) to protect DoD information and resources. The importance of strong encryption and VPNs for our mobile workforce is imperative. Last October, the Department outlined its layered cybersecurity approach to protect DoD information and resources, including service men and women, when using mobile communications capabilities.
As the use of mobile devices continues to expand, it is imperative that innovative security techniques, such as advanced encryption algorithms, are constantly maintained and improved to protect DoD information and resources. The Department believes maintaining a domestic climate for state of the art security and encryption is critical to the protection of our national security.
This is interesting research:
In a BGP hijack, a malicious actor convinces nearby networks that the best path to reach a specific IP address is through their network. That’s unfortunately not very hard to do, since BGP itself doesn’t have any security procedures for validating that a message is actually coming from the place it says it’s coming from.
To better pinpoint serial attacks, the group first pulled data from several years’ worth of network operator mailing lists, as well as historical BGP data taken every five minutes from the global routing table. From that, they observed particular qualities of malicious actors and then trained a machine-learning model to automatically identify such behaviors.
The system flagged networks that had several key characteristics, particularly with respect to the nature of the specific blocks of IP addresses they use:
- Volatile changes in activity: Hijackers’ address blocks seem to disappear much faster than those of legitimate networks. The average duration of a flagged network’s prefix was under 50 days, compared to almost two years for legitimate networks.
- Multiple address blocks: Serial hijackers tend to advertise many more blocks of IP addresses, also known as “network prefixes.”
- IP addresses in multiple countries: Most networks don’t have foreign IP addresses. In contrast, for the networks that serial hijackers advertised that they had, they were much more likely to be registered in different countries and continents.
Note that this is much more likely to detect criminal attacks than nation-state activities. But it’s still good work.
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.
