Dairy cows fed industrial hemp produced milk with detectable levels of the buzz-inducing molecular compound THC, according to a new study from Germany that could influence the potential uses of hemp as an ingredient in animal feed. The dairy cows also showed behavioral changes — yawning and salivating a lot, moving a little unsteadily on their hoofs, standing in one place for a protracted period, and having a “somnolent appearance.” The Washington Post reports: The peer-reviewed study, conducted on Holstein cows in Berlin and published Monday in the journal Nature Food, is one of the first major investigations of the use of industrial hemp as a potential supplement in animal feed. For now, such use is illegal under U.S. law, which does not allow THC in the food chain. But the new research comes as hemp, which has many industrial uses, continues to emerge from an agricultural exile that dates to the “reefer madness” hysteria of the 1930s. […]

The researchers at the German Federal Institute for Risk Assessment found no behavioral change in cows given the entire hemp plant, which contained very low levels of THC. Only when fed solely the portions of the hemp plant with higher THC concentrations — including the flowers and leaves — did the behavioral effects appear, according to the study. Those effects included slower heart rate and respiration, “pronounced tongue play, increased yawning, salivation, nasal secretion formation,” and reddening of a portion of the eyes, the report states. Some animals “displayed careful, occasionally unsteady gait, unusually long standing and abnormal posture.” The animals also ate less and produced less milk, according to Robert Pieper, head of the department of food chain safety for the institute and co-author of the new paper. “That is a strong effect on animal health. Not a positive effect,” he said. But he did not predict how it would play out in the policy world.

An anonymous reader quotes a report from Ars Technica: Privacy-focused search site DuckDuckGo has added yet another way to prevent more of your data from going to advertisers, opening its App Tracking Protection for Android to beta testers. DuckDuckGo is positioning App Tracking Protection as something like Apple’s App Tracking Transparency for iOS devices, but “even more powerful.” Enabling the service in the DuckDuckGo app for Android (under the “More from DuckDuckGo” section) installs a local VPN service on your phone, which can then start automatically blocking trackers on DDG’s public blocklist. DuckDuckGo says this happens “without sending app data to DuckDuckGo or other remote servers.”

Google recently gave Android users some native tools to prevent wanton tracking, including app-by-app location-tracking approval and a limited native ad-tracking opt-out. Apple’s App Tracking Transparency asks if users want to block apps from accessing the Identifier for Advertisers (IDFA), but apps can still use the largest tracking networks across many apps to better profile app users. Allison Goodman, senior communications manager for DuckDuckGo, told Ars Technica that App Tracking Protection needs Android’s VPN permission so it can monitor network traffic. When it recognizes a tracker from its blocklist, it “looks at the destination domain for any outbound request and blocks them if they are in our blocklist and the requesting app is not owned by the same company that owns the domain.” Goodman added that “much of the data collected by trackers is not controlled by [Android] permissions,” making App Tracking Protection a complementary offering.

Researchers have developed a fentanyl vaccine that could eliminate the drug’s “high” by blocking its ability to enter the brain — which could be a major step forward in the ongoing opioid crisis. Yahoo News reports: The study, conducted by a research team led by the University of Houston and funded by the Department of Defense through the Alcohol and Substance Abuse Disorder Research Program, was published in the journal Pharmaceutics at the end of October. Colin Haile, a research associate professor of psychology and lead author of the study, said in a news release that the vaccine “is able to generate anti-fentanyl antibodies that bind to the consumed fentanyl and prevent it from entering the brain, allowing it to be eliminated out of the body via the kidneys. “Thus, the individual will not feel the euphoric effects and can “get back on the wagon’ to sobriety.”

Haile added that the anti-fentanyl antibodies didn’t cross-react with other opioids, meaning a vaccinated person could still be treated for pain relief with other opioids. The vaccine did not cause any adverse side effects in rats involved in lab studies, and clinical trials in humans are planned “soon,” with manufacturing of clinical-grade vaccine to begin in the coming months.

An anonymous reader quotes a report from BleepingComputer: The FBI and CISA revealed in a joint advisory published today that an unnamed Iranian-backed threat group hacked a Federal Civilian Executive Branch (FCEB) organization to deploy XMRig cryptomining malware. The attackers compromised the federal network after hacking into an unpatched VMware Horizon server using an exploit targeting the Log4Shell (CVE-2021-44228) remote code execution vulnerability. After deploying the cryptocurrency miner, the Iranian threat actors also set up reverse proxies on compromised servers to maintain persistence within the FCEB agency’s network.

“In the course of incident response activities, CISA determined that cyber threat actors exploited the Log4Shell vulnerability in an unpatched VMware Horizon server, installed XMRig crypto mining software, moved laterally to the domain controller (DC), compromised credentials, and then implanted Ngrok reverse proxies on several hosts to maintain persistence,” the joint advisory reads. The two U.S. federal agencies added that all organizations who haven’t yet patched their VMware systems against Log4Shell should assume that they’ve already been breached and advise them to start hunting for malicious activity within their networks.

CISA warned in June that VMware Horizon and Unified Access Gateway (UAG) servers are still being preyed upon by multiple threat actors, including state-sponsored hacking groups, using Log4Shell exploits. Log4Shell can be exploited remotely to target vulnerable servers exposed to local or Internet access to move laterally across breached networks to access internal systems that store sensitive data.
