New “Chameleon” Attack Can Secretly Modify Content on Facebook, Twitter. or LinkedIn: That video or picture you “liked” on social media of a cute dog, your favorite team or political candidate can actually be altered in a cyberattack to something completely different, detrimental and potentially criminal.

The Department of Homeland Security (DHS) said that on Thursday it started processing migrants for return to Mexico under the Migrant Protection Protocols (MPP) at the Nogales Port of Entry south of Tucson, Arizona. This brings the total number of ports of entry where MPP returns will be made to seven.

Beginning in May, the State Department has required almost every applicant for a U.S. visa—more than fourteen million people each year—to register every social media handle they’ve used over the past five years on any of twenty platforms. “There is no evidence that the social media registration requirement serves the government’s professed goals” of “strengthen” the processes for “vetting applicants and confirming their identity,” Carrie DeCell and Harsha Panduranga write, adding: “The registration requirement chills the free speech of millions of prospective visitors to the United States, to their detriment and to ours,” they write.

In 2018, following a series of violent incidents in Mjolnerparken, a sprawling housing projects on the outskirts of Copemhagen which is home mostly to Muslim immigrants, the Danish government drafted, and the Danish parliament approved, a new “ghetto” law, aimed at dealing more effectively with the ills of ethnic enclaves. “Denmark’s ghetto law reflects growing European discomfort with districts dominated by ethnic-minority groups,” the Economist notes. “From Oslo to Milan, grumpy natives complain of districts that no longer feel like the country they grew up in.”

The Department of Homeland Security lacked a technology system to efficiently track separated migrant families during the execution of the zero tolerance immigration policy in 2018, a report released Wednesday by the agency’s inspector general found.

It may not be just location, location, location that influences where people move to in the United States, but also politics, politics, politics, according to a team of researchers. In a study of county-to-county migration patterns in the U.S., the researchers found that when people migrate, they tend to move to other counties that reflect their political preferences. They added that the pattern also suggests that people moving from moderate partisan counties are just as likely to move to extreme partisan counties as they are to move to other moderate counties.

The efforts to foster America’s development of artificial intelligence, including for military use, typically overlook how the U.S. current advantage depends on immigrants. “Without immigration reforms, this country’s days as the world’s AI leader may be numbered,” Zachary Arnold writes. “Immigration reform of any sort may be a tall order nowadays, but the dawn of the AI age is reason enough to redouble those efforts,” he adds.

The Trump administration wants to make people fleeing persecution in their home countries pay for something they’ve long gotten for free: the right to apply for asylum in the United States. At present, only Iran, Australia and Fiji charge fees to would-be asylum-seekers. 

Russian President Vladimir Putin suggested to the West last month that the widening chaos in Libya after almost a decade of war should have been obvious: “A flow of migrants went through Libya to Europe,” he said in an interview, recalling the displacement of refugees that has reached crisis levels in recent years. “They have what they were warned about.” This week, the New York Times documented the deployment into Libya of Russian mercenaries. “The Russian leader’s warning about Libya, many analysts believe, reflects an ambition to intervene in the conflict at least in part to control refugee flows into Europe, indicating a broad understanding of the disruptive power that the movement of immigrants has had on the Western world,” Paul Shinkman writes.
