Invisible Web: What it is, Why it exists, How to find it, and Its inherent ambiguity - 1 views

  •  
    [What is the "Invisible Web", a.k.a. the "Deep Web"? The "visible web" is what you can find using general web search engines. It's also what you see in almost all subject directories. The "invisible web" is what you cannot find using these types of tools. The first version of this web page was written in 2000, when this topic was new and baffling to many web searchers. Since then, search engines' crawlers and indexing programs have overcome many of the technical barriers that made it impossible for them to find "invisible" web pages. These types of pages used to be invisible but can now be found in most search engine results: Pages in non-HTML formats (pdf, Word, Excel, PowerPoint), now converted into HTML. Script-based pages, whose URLs contain a ? or other script coding. Pages generated dynamically by other types of database software (e.g., Active Server Pages, Cold Fusion). These can be indexed if there is a stable URL somewhere that search engine crawlers can find. ]

United States v. Cano, No. 17-50151 (9th Cir. 2019) :: Justia - 0 views

  • The Ninth Circuit reversed the district court's denial of defendant's motion to suppress evidence obtained from warrantless searches of his cell phone by a Customs and Border Patrol official. Applying United States v. Cotterman, 709 F.3d 952 (9th Cir. 2013) (en banc), the panel held that manual cell phone searches may be conducted by border officials without reasonable suspicion but that forensic cell phone searches require reasonable suspicion. The panel clarified Cotterman by holding that "reasonable suspicion" in this context means that officials must reasonably suspect that the cell phone contains digital contraband. Furthermore, cell phone searches at the border, whether manual or forensic, must be limited in scope to a search for digital contraband. In this case, the panel held that the officials violated the Fourth Amendment when their warrantless searches exceeded the permissible scope of a border search. Therefore, most of the evidence from the searches of defendant's cell phone should have been suppressed. Finally, the panel held that defendant's Brady claims were unpersuasive. Because the panel vacated defendant's conviction, the panel did not reach his claim of prosecutorial misconduct.

Home - schema.org - 0 views

  • What is Schema.org? This site provides a collection of schemas, i.e., html tags, that webmasters can use to markup their pages in ways recognized by major search providers. Search engines including Bing, Google, Yahoo! and Yandex rely on this markup to improve the display of search results, making it easier for people to find the right web pages. Many sites are generated from structured data, which is often stored in databases. When this data is formatted into HTML, it becomes very difficult to recover the original structured data. Many applications, especially search engines, can benefit greatly from direct access to this structured data. On-page markup enables search engines to understand the information on web pages and provide richer search results in order to make it easier for users to find relevant information on the web. Markup can also enable new tools and applications that make use of the structure. A shared markup vocabulary makes it easier for webmasters to decide on a markup schema and get the maximum benefit for their efforts. So, in the spirit of sitemaps.org, search engines have come together to provide a shared collection of schemas that webmasters can use.

DOJ Pushes to Expand Hacking Abilities Against Cyber-Criminals - Law Blog - WSJ - 0 views

  • The U.S. Department of Justice is pushing to make it easier for law enforcement to get warrants to hack into the computers of criminal suspects across the country. The move, which would alter federal court rules governing search warrants, comes amid increases in cases related to computer crimes. Investigators say they need more flexibility to get warrants to allow hacking in such cases, especially when multiple computers are involved or the government doesn’t know where the suspect’s computer is physically located. The Justice Department effort is raising questions among some technology advocates, who say the government should focus on fixing the holes in computer software that allow such hacking instead of exploiting them. Privacy advocates also warn government spyware could end up on innocent people’s computers if remote attacks are authorized against equipment whose ownership isn’t clear.
  • The government’s push for rule changes sheds light on law enforcement’s use of remote hacking techniques, which are being deployed more frequently but have been protected behind a veil of secrecy for years. In documents submitted by the government to the judicial system’s rule-making body this year, the government discussed using software to find suspected child pornographers who visited a U.S. site and concealed their identity using a strong anonymization tool called Tor. The government’s hacking tools—such as sending an email embedded with code that installs spying software — resemble those used by criminal hackers. The government doesn’t describe these methods as hacking, preferring instead to use terms like “remote access” and “network investigative techniques.” Right now, investigators who want to search property, including computers, generally need to get a warrant from a judge in the district where the property is located, according to federal court rules. In a computer investigation, that might not be possible, because criminals can hide behind anonymizing technologies. In cases involving botnets—groups of hijacked computers—investigators might also want to search many machines at once without getting that many warrants.
  • Some judges have already granted warrants in cases when authorities don’t know where the machine is. But at least one judge has denied an application in part because of the current rules. The department also wants warrants to be allowed for multiple computers at the same time, as well as for searches of many related storage, email and social media accounts at once, as long as those accounts are accessed by the computer being searched. “Remote searches of computers are often essential to the successful investigation” of computer crimes, Acting Assistant Attorney General Mythili Raman wrote in a letter to the judicial system’s rulemaking authority requesting the change in September. The government tries to obtain these “remote access warrants” mainly to “combat Internet anonymizing techniques,” the department said in a memo to the authority in March. Some groups have raised questions about law enforcement’s use of hacking technologies, arguing that such tools mean the government is failing to help fix software problems exploited by criminals. “It is crucial that we have a robust public debate about how the Fourth Amendment and federal law should limit the government’s use of malware and spyware within the U.S.,” said Nathan Wessler, a staff attorney at the American Civil Liberties Union who focuses on technology issues.

  • A Texas judge who denied a warrant application last year cited privacy concerns associated with sending malware when the location of the computer wasn’t known. He pointed out that a suspect opening an email infected with spyware could be doing so on a public computer, creating risk of information being collected from innocent people. A former computer crimes prosecutor serving on an advisory committee of the U.S. Judicial Conference, which is reviewing the request, said he was concerned that allowing the search of multiple computers under a single warrant would violate the Fourth Amendment’s protections against overly broad searches. The proposed rule is set to be debated by the Judicial Conference’s Advisory Committee on Criminal Rules in early April, after which it would be opened to public comment.

Microsoft Says U.S. Is Abusing Secret Warrants - 0 views

  • “WE APPRECIATE THAT there are times when secrecy around a government warrant is needed,” Microsoft President Brad Smith wrote in a blog post on Thursday. “But based on the many secrecy orders we have received, we question whether these orders are grounded in specific facts that truly demand secrecy. To the contrary, it appears that the issuance of secrecy orders has become too routine.” With those words, Smith announced that Microsoft was suing the Department of Justice for the right to inform its customers when the government is reading their emails. The last big fight between the Justice Department and Silicon Valley was started by law enforcement, when the FBI demanded that Apple unlock a phone used by San Bernardino killer Syed Rizwan Farook. This time, Microsoft is going on the offensive. The move is welcomed by privacy activists as a step forward for transparency — though it’s also for business reasons.
  • Secret government searches are eroding people’s trust in the cloud, Smith wrote — including large and small businesses now keeping massive amounts of records online. “The transition to the cloud does not alter people’s expectations of privacy and should not alter the fundamental constitutional requirement that the government must — with few exceptions — give notice when it searches and seizes private information or communications,” he wrote. According to the complaint, Microsoft received 5,624 federal demands for customer information or data in the past 18 months. Almost half — 2,576 — came with gag orders, and almost half of those — 1,752 — had “no fixed end date” by which Microsoft would no longer be sworn to secrecy. These requests, though signed off on by a judge, qualify as unconstitutional searches, the attorneys argue. It “violates both the Fourth Amendment, which affords people and businesses the right to know if the government searches or seizes their property, and the First Amendment, which enshrines Microsoft’s rights to talk to its customers and to discuss how the government conducts its investigations — subject only to restraints narrowly tailored to serve compelling government interests,” they wrote.
  •  
    The Fourth Amendment argument that people have a right to know when their property has been searched or seized is particularly interesting to me. If adopted by the Courts, that could spell the end of surveillance gag orders.

US judge slams surveillance requests as "repugnant to the Fourth Amendment" - World Soc... - 0 views

  • Federal Magistrate Judge John M. Facciola denied a US government request earlier this month for a search and seizure warrant, targeting electronic data stored on Apple Inc. property. Facciola’s order, issued on March 7, 2014, rejected what it described as only the latest in a series of “overbroad search and seizure requests,” and “unconstitutional warrant applications” submitted by the US government to the US District Court for the District of Columbia. Facciola referred to the virtually unlimited warrant request submitted by the Justice Department as “repugnant to the Fourth Amendment.” The surveillance request sought information in relation to a “kickback investigation” of a defense contractor, details about which remain secret. It is significant, however, that the surveillance request denied by Facciola relates to a criminal investigation, unrelated to terrorism. This demonstrates that the use by the Obama administration of blanket warrants enabling them to seize all information on a person's Internet accounts is not limited to terrorism, as is frequently claimed, but is part of a program of general mass illegal spying on the American people.
  • Facciola’s ruling states in no uncertain terms that the Obama administration has aggressively and repeatedly sought expansive, unconstitutional warrants, ignoring the court’s insistence for specific, narrowly targeted surveillance requests. “The government continues to submit overly broad warrants and makes no effort to balance the law enforcement interest against the obvious expectation of privacy email account holders have in their communications…The government continues to ask for all electronically stored information in email accounts, irrespective of the relevance to the investigation,” wrote Judge Facciola. As stated in the ruling, the surveillance requests submitted to the court by the US government sought the following comprehensive, virtually limitless list of information about the target: “All records or other information stored by an individual using each account, including address books, contact and buddy lists, pictures, and files… All records or other information regarding the identification of the accounts, to include full name, physical address, telephone numbers and other identifies, records of session times and durations, the date on which each account was created, the length of service, the types of service utilized, the Internet Protocol (IP) address used to register each account, log-in IP addresses associated with session times and dates, account status, alternative email addresses provided during registration, methods of connecting, log files, and means of payment (including any credit or bank account number).”
  • Responding to these all-encompassing warrant requests, Judge Facciola ruled that evidence of probable cause was necessary for each specific item sought by the government. “This Court is increasingly concerned about the government’s applications for search warrants for electronic data. In essence, its applications ask for the entire universe of information tied to a particular account, even if it has established probable cause only for certain information,” Facciola wrote. “It is the Court’s duty to reject any applications for search warrants where the standard of probable cause has not been met… To follow the dictates of the Fourth Amendment and to avoid issuing a general warrant, a court must be careful to ensure that probable cause exists to seize each item specified in the warrant application… Any search of an electronic source has the potential to unearth tens or hundreds of thousands of individual documents, pictures, movies, or other constitutionally protected content.” Facciola also noted in the ruling that the government never reported the length of time it would keep the data, or whether it planned to destroy the data at any point.

  • Facciola’s ruling represents a reversal from a previous ruling, in which a Kansas judge allowed the government to conduct such unlimited searches of Yahoo accounts.
  • In testimony, De and his deputy Brad Wiegmann rejected the privacy board’s advice that the agency limit its data mining to specific targets approved by specific warrants. “If you have to go back to court every time you look at the information in your custody, you can imagine that would be quite burdensome,” said Wiegmann. De further said on the topic, “That information is at the government’s disposal to review in the first instance.” As these statements indicate, the intelligence establishment rejects any restrictions on their prerogative to spy on every aspect of citizens lives at will, even the entirely cosmetic regulations proposed by the Obama administration-appointed PCLOB.

Supreme Court Says Phones Can't Be Searched Without a Warrant - NYTimes.com - 0 views

  • In a sweeping victory for privacy rights in the digital age, the Supreme Court on Wednesday unanimously ruled that the police need warrants to search the cellphones of people they arrest.While the decision will offer protection to the 12 million people arrested every year, many for minor crimes, its impact will most likely be much broader. The ruling almost certainly also applies to searches of tablet and laptop computers, and its reasoning may apply to searches of homes and businesses and of information held by third parties like phone companies.“This is a bold opinion,” said Orin S. Kerr, a law professor at George Washington University. “It is the first computer-search case, and it says we are in a new digital age. You can’t apply the old rules anymore.”
  •  
    It is now beyond doubt that the Supreme Court is declining to authorize an Orwellian government surveillance future for the U.S. This sweeping, unanimous ruling definitely has broad application beyond cellphones, in no small part because the court recognized that cellphones of today are more like desktop computers and a host of other computerized devices than they are like the telephones of yesteryear. Hence, almost everything the court said afterward about the privacy rights in cellphones applies equally to all personal use computers.

NSA contractors use LinkedIn profiles to cash in on national security | Al Jazeera America - 0 views

  • NSA spies need jobs, too. And that is why many covert programs could be hiding in plain sight. Job websites such as LinkedIn and Indeed.com contain hundreds of profiles that reference classified NSA efforts, posted by everyone from career government employees to low-level IT workers who served in Iraq or Afghanistan. They offer a rare glimpse into the intelligence community's projects and how they operate. Now some researchers are using the same kinds of big-data tools employed by the NSA to scrape public LinkedIn profiles for classified programs. But the presence of so much classified information in public view raises serious concerns about security — and about the intelligence industry as a whole. “I’ve spent the past couple of years searching LinkedIn profiles for NSA programs,” said Christopher Soghoian, the principal technologist with the American Civil Liberties Union’s Speech, Privacy and Technology Project.
  • On Aug. 3, The Wall Street Journal published a story about the FBI’s growing use of hacking to monitor suspects, based on information Soghoian provided. The next day, Soghoian spoke at the Defcon hacking conference about how he uncovered the existence of the FBI’s hacking team, known as the Remote Operations Unit (ROU), using the LinkedIn profiles of two employees at James Bimen Associates, with which the FBI contracts for hacking operations. “Had it not been for the sloppy actions of a few contractors updating their LinkedIn profiles, we would have never known about this,” Soghoian said in his Defcon talk. Those two contractors were not the only ones being sloppy.
  • And there are many more. A quick search of Indeed.com using three code names unlikely to return false positives — Dishfire, XKeyscore and Pinwale — turned up 323 résumés. The same search on LinkedIn turned up 48 profiles mentioning Dishfire, 18 mentioning XKeyscore and 74 mentioning Pinwale. Almost all these people appear to work in the intelligence industry. Network-mapping the data Fabio Pietrosanti of the Hermes Center for Transparency and Digital Human Rights noticed all the code names on LinkedIn last December. While sitting with M.C. McGrath at the Chaos Communication Congress in Hamburg, Germany, Pietrosanti began searching the website for classified program names — and getting serious results. McGrath was already developing Transparency Toolkit, a Web application for investigative research, and knew he could improve on Pietrosanti’s off-the-cuff methods.

  • “I was, like, huh, maybe there’s more we can do with this — actually get a list of all these profiles that have these results and use that to analyze the structure of which companies are helping with which programs, which people are helping with which programs, try to figure out in what capacity, and learn more about things that we might not know about,” McGrath said. He set up a computer program called a scraper to search LinkedIn for public profiles that mention known NSA programs, contractors or jargon — such as SIGINT, the agency’s term for “signals intelligence” gleaned from intercepted communications. Once the scraper found the name of an NSA program, it searched nearby for other words in all caps. That allowed McGrath to find the names of unknown programs, too. Once McGrath had the raw data — thousands of profiles in all, with 70 to 80 different program names — he created a network graph that showed the relationships between specific government agencies, contractors and intelligence programs. Of course, the data are limited to what people are posting on their LinkedIn profiles. Still, the network graph gives a sense of which contractors work on several NSA programs, which ones work on just one or two, and even which programs military units in Iraq and Afghanistan are using. And that is just the beginning.

EFF to Court: U.S. Warrants Don't Apply to Overseas Emails | Electronic Frontier Founda... - 0 views

  • The Electronic Frontier Foundation (EFF) has urged a federal court to block a U.S. search warrant ordering Microsoft to turn over a customer's emails held in an overseas server, arguing that the case has dangerous privacy implications for Internet users everywhere. The case started in December of last year, when a magistrate judge in New York signed a search warrant seeking records and emails from a Microsoft account in connection with a criminal investigation. However, Microsoft determined that the emails the government sought were on a Microsoft server in Dublin, Ireland. Because a U.S. judge has no authority to issue warrants to search and seize property or data abroad, Microsoft refused to turn over the emails and asked the magistrate to quash the warrant. But the magistrate denied Microsoft's request, ruling there was no foreign search because the data would be reviewed by law enforcement agents in the U.S.
  • Microsoft appealed the decision. In an amicus brief in support of Microsoft, EFF argues the magistrate's rationale ignores the fact that copying the emails is a "seizure" that takes place in Ireland. "The Fourth Amendment protects from unreasonable search and seizure. You can't ignore the 'seizure' part just because the property is digital and not physical," said EFF Staff Attorney Hanni Fakhoury. "Ignoring this basic point has dangerous implications – it could open the door to unfounded law enforcement access to and collection of data stored around the world."

Expert System Guns for Google with Semantic Search, Advertising - 0 views

  • Would-be Google AdSense rival Expert System launches its Cogito Semantic Advertiser tool, which discerns the meaning and context of words to provide more relevant ads. By leveraging semantic technologies, Expert System joins a cadre of search providers that includes Microsoft-owned Powerset, Hakia, Yedda and Zoomix.
  • The problem is that AdSense relies on keyword frequency but doesn't drill down into the semantics—the meaning in the words. Cogito Semantic Advertiser attempts to go further by using semantic intelligence to analyze the text on each page and ensure that ads are placed appropriately to increase click-through rates.
  • Asher told me Cogito Semantic Advertiser understands content based on four key methodologies: studying the morphology of words; looking at parts of speech; sentence logic, or the reduction of sentences to subject, verb and object; and disambiguation, which in the case of the jaguar story paired with the Jaguar car ad would determine whether or not the text referred to a car or an animal.
