Florida homecoming queen faces up to 16 years after alleged scheme to hack high school contest

A teenager accused of gaining unauthorized access to school computer systems in order to rig a homecoming queen contest with her mother will stand trial as an adult, and could spend 16 years in prison if convicted. Emily Grover, who turned 18 in April but who was arrested in March, when she was 17, faces four charges alongside her mother, Laura Carroll. Carroll was an assistant principal at Bellview Elementary School, while her daughter attended Tate High School. The pair allegedly schemed to cast hundreds of fraudulent votes in the homecoming contest, an election that Grover ultimately won. A Florida State Department of Law Enforcement investigation concluded that phones and computers from their Pensacola suburb household were used to access student records. “The primary reason for the decision is, she was almost 18 years of age and would age out of the juvenile system in a very short period of […] The post Florida homecoming queen faces up to 16 years after alleged scheme to hack high school contest appeared first on CyberScoop.

Twitter restricts account of Intrusion Truth, which doxxes suspected Chinese hackers

Twitter on Tuesday moved to restrict the account of a mysterious group that has published details on suspected state-sponsored hackers from China. The group, Intrusion Truth, had spent recent days hinting that it would go public with new allegations against possible hackers, teasing followers with messages like “Watch this space” and “Who’s excited? We are.” The identity of the person or group behind Intrusion Truth has remained elusive since it started publishing information in 2017, including missives about how Chinese technology companies allegedly supported espionage on Beijing’s behalf. Intrusion Truth’s Twitter account suggested it would publish new information on Wednesday about “hackers based in Chengdu,” a city in southwestern China. Twitter, though, plastered a warning on the account, saying that the account was “temporarily restricted” because “there has been some unusual activity.” Users still could access the page at press time Tuesday, though they would need to click through to […] The post Twitter restricts account of Intrusion Truth, which doxxes suspected Chinese hackers appeared first on CyberScoop.

Qualys researchers uncover 21 bugs in Exim mail servers

Researchers have found 21 unique vulnerabilities in Exim, a popular mail transfer agent, some of which would allow hackers to run full remote unauthenticated code execution against targets, the Qualys Research Team announced Tuesday. If used properly, attackers could execute commands to install programs, manipulate data, create new accounts or change settings on the mail servers, according to the research. CVE-2020-28017, one of the vulnerabilities, dates as far back as 2004, according to the findings. Qualys and Exim recommend users apply the patches immediately. The Exim Mail Transfer Agent (MTA) vulnerabilities, which Qualys is referring to collectively as 21Nails, affect all versions before Exim-4.94.1. Ten of the flaws can be executed to gain root privileges, while 11 of them can be used to exploit victim systems locally. Hackers could link several of the vulnerabilities together in an attack to run full remote unauthenticated code execution against vulnerable mail servers, Qualys […] The post Qualys researchers uncover 21 bugs in Exim mail servers appeared first on CyberScoop.

Hackers disrupt networks at San Diego medical provider, Kansas organ transplant facilitator

A pair of hacks at health care organizations revealed in recent days highlights the enduring cybercriminal threat to the sector as the U.S. makes progress in fighting the coronavirus pandemic. Scripps Health, a San Diego-based nonprofit system with five hospital campuses, on May 1 said that it had suspended access to IT applications that support its health care facilities following a “security incident.” The incident forced Scripps to reschedule some patient appointments for Saturday and Monday, but “patient care continues to be delivered safely and effectively at our facilities,” the nonprofit said in a statement on its Facebook page. (Scripps’ website was still down by press time on Tuesday morning.) Meanwhile, Midwest Transplant Network, a Kansas-based organization that connects organ donors with recipients, said it had been working to determine if patients’ personal health data had been affected by a recent breach. NPR affiliate KCUR reported that some 17,000 people […] The post Hackers disrupt networks at San Diego medical provider, Kansas organ transplant facilitator appeared first on CyberScoop.

After more than a decade, SentinelOne researchers weed out Dell vulnerabilities

Since 2009, vulnerabilities have lurked in Dell drivers that potentially affect hundreds of millions of machines, SentinelOne researchers said on Tuesday. Hackers could use the vulnerabilities to instigate a range of attacks, from ransomware to wipers that can erase hard drives, said J.A. Guerrero-Saade, principle threat researcher at the security firm. “They can basically do whatever they want,” Guerrero-Saade told CyberScoop. Dell released mitigation steps on Tuesday in advance of SentinelOne publishing its research. Those flaws sitting undiscovered for 12 years is not unheard of, despite a whole industry of security researchers dedicated to weeding out bugs that could abet cyberattacks. A 2017 study found that a quarter of zero-day vulnerabilities remain hidden for more than nine and a half years. In the case of the Dell flaws, Guerrero-Saade said their dormant nature reflects a “target-rich environment,” especially as it pertains to drivers that allow computers to communicate with hardware.

How Should the Service Desk Reset Passwords?
