A starting point for investigators trying to trace the bombs sent to Democratic figures and CNN this week: the postmark.But in some cases, it appears to be a missing clue.The postmark typically indicates when and where the mail was sent from and is marked over the stamps -- "canceling" them, and preventing the stamps from being reused. Unlike stamps, most of which cannot be traced, the impression left by a postmark or mail meter is distinctive and can help investigators focus their search.A postmark is visible in a photo of at least one of the packages seen by CNN. A postmark is not visible in photos of several other packages shared with CNN -- only adding to the questions about their origins.The lack of a postmark is very rare, according to Nancy Pope of the National Postal Museum.A postal inspector who spoke to CNN on the condition of anonymity indicated it would be very unusual for a piece of mail to leave the facility where it was dropped off for delivery without such a mark.That could indicate that a sender or senders were working in multiple diverse geographical areas, including New York, Washington, Florida and California.Another source told CNN it is possible some of the stamps may not have been canceled because of the package's soft sides and odd shape, which would make it difficult to stamp.The US Postal Service's website also says mail may not be postmarked if it was processed through a meter or if the postage was paid by permit or precanceled stamp. None of those appear to apply to this situation.Adding to the mystery are post office markings on one of two packages sent to former Vice President Joe Biden indicating the stamps on the package did not cover the cost of the delivery, and additional postage is due.That suggests the package was weighed at some point during the shipping process, a former postal inspector told CNN.It was unclear from the photo whether that package had been postmarked.Postmarks can be applied by machine and by hand, depending on how a piece of mail is sent, according to the Postal Service. When mail is run through an automated system at a processing distribution center, the postmark is applied, and the mailed item is screened by a biohazard detection system.It was not clear why postmarks were not visible on several of the packages, and the US Postal Inspection Service provided a statement to CNN that did not address the question."The U.S. Postal Service has developed a comprehensive approach to protecting the mailsystem by utilizing a targeted strategy of specialized technology, screening protocols and employee training," read the statement.The statement noted its Dangerous Mail Investigations Program includes law enforcement officers who "are trained to recognize the common characteristics of suspicious mail and are highly proficient in the use of state-of-the-art equipment to include portable X-ray machines." 2907

A teacher at Dickson Intermediate School in Tennessee launched an emergency lunch money fund for students after an interaction with one child inspired her to help children in need."As I was walking through the cafeteria one day, I saw a child with no tray and no drink just stopped to build those relationships as teacher do, and just asked are you not eating? Do you need something?" said sixth grade literary teacher Julie Potter. "His comment was mom said we’re out of money so I can’t eat today."Potter told the student to grab lunch, on her.But she said she realized that was a short term solution."I thought if I could just donate just a few dollars to set up an account so the next time, the next child will feel safe enough to go through the line without worrying about pride and be fed," Potter said.So Potter put out a post on Facebook, detailing her interaction with the student and a plan to help others."I share this message to say I would like to set up a special lunch account called 1 in 4," the post read. "This account would be for those students, just a handful and only as needed, we see going without food. An account where we as school staff could quietly say, 'Go through the line and it will be taken care of.'"In just 10 days, teachers and parents have donated to the fund and two students have used the emergency money to eat.And while Dickson Intermediate never turns away a hungry student, officials said this helps further break down barriers."Some are going to feel a little embarrassed or shy about asking for help," said School Nutrition Supervisor Jason Collins. "That’s why I think it’s so important that we focus on building those relationships."According to Feed America about one in four children in Dickson County are food insecure but don't qualify for federal assistance.If you'd like to donate to Dickson Intermediate's fund you can drop money off at the school's front office or mail it to the school. Please specify that your donation is for the 1 in 4 lunch account. 2063

A massive scam related to COVID-19 that targeted millions of Office 365 users in 62 countries was stopped by Microsoft's digital crimes unit.The department is almost like a police department. There's even an evidence room. It's an office that is only known to the people whose job it is to investigate attacks on Microsoft customers. They're a small group, but they're mighty.Tom Burt, the Corporate Vice President for Customer Security and Trust, said the team is comprised of "lawyers, forensic investigators data analysts, business people."Burt is in charge of the cybersecurity team that goes after cybercriminals. Their job is to find, intercept and then help law enforcement stop the scam artists in their tracks."(We're) looking for things that we shouldn't be seeing in the data relevant to how Office 365 was being used by our costumers," Burt said. "When we see that we can dive deeper, look at the metadata and look at the information that's streaming through our Office 365 global network — to try to find indicators of people doing bad things."The team often uses social media to alert people to the hacks they're seeing.Cybercriminals often target people's fears and anxiety. So, these days, the coronavirus pandemic is a good hook.One of the recent lures was a "cure for coronavirus" or "COVID-19 safety tips" from the Red Cross. The hackers were hoping Officer 365 users would take the bait and click."They're able to get control of users' Office 365 accounts," Burt said. "They can then see what's going on in that account. They can act as if they're you — they can send email in your name and look to find things in your email account like passwords and other information."Burt says the hackers are good. They do research and figure out how companies are structured and who does what. They'll look at social sites and figure out exactly who to target.Some of the scams people were getting involved co-workers asking others to transfer money to an account."They're sophisticated criminals," Burt said. 'They do this work to make sure the requests look legitimate so they can be successful in stealing money."Burt says there's an easy way to prevent phishing attacks."The number one thing by far is to utilize two factor authentication on all of your accounts," he said. "If you're a business,s make sure you're doing that for your business email if you're an individual, make sure you're doing it for your individual email and financial accounts."Burt is referencing the separate codes a user gets when logging on to a website. The site will give a prompt so they can prove that they are.The cybersecurity team says two-fact authentication will eliminate 98-99 percent of attacks.The challenge has always been to find the cybercriminals. So, this time around, the digital unit went around them."We're saying, let's stop them in a different way," Burt said. "Let's take the internet tools that they're using to conduct their crime, and let's go legally take those tools away from them."Court documents from the civil case filed in Federal Court say that Microsoft has the authority to take away the tools the hackers need to conduct their scams."Basically, websites, locations on the internet from which they can conduct their fraudulent activities — whether it's launching their efforts or the place where they want you to ultimately go — we go with the court order to those registrars and transfer those domains to Microsoft control," Burt said.Doing that strips hackers' access and gives Microsoft the ability to block them."We took down the criminal infrastructure that was being used to defraud people in 62 countries," Burt said. "We're going to keep doing that work. We're committed. Its fun, it's fascinating and, most importantly, it protects our customers." 3791

A Southwest Airlines flight from Chicago to Newark, New Jersey, made an unplanned landing Wednesday after a window cracked, the Federal Aviation Administration and passengers said.Flight 957 was diverted to Cleveland after a report of an issue with a window aboard the aircraft, FAA spokeswoman Elizabeth Cory said. It landed safely at Cleveland Hopkins International Airport, she said.Passenger Linda Holley texted her son Ryan with a picture of the damaged window."Window on plane cracked during flight. Landing in Cleveland to be safe. Everything ok but scary," one of her texts read.In another, she said: "Yes Southwest. Just heard loud noise. Very large crack with piece of window missing at bottom. Just landed. Everything ok. Don't know plan yet"The FAA said it will investigate what caused the window to crack. So far, the cause is not known.There was no depressurization in the cabin, and therefore the oxygen masks were not deployed, FAA spokesman Greg Martin said. He said the pilot did not declare an emergency but did ask to divert to a nearby airport.This is the second high-profile flight diversion by a Southwest Airlines plane in less than three weeks.On April 17, Southwest Flight 1380 made an emergency landing after an engine was damaged mid-flight.One person died after being partially sucked out a window. But passengers and even the President lauded Captain Tammie Jo Shults for safely landing the plane. 1435
