    sudo had a bug: Potential bypass of Runas user restrictions (CVE-2019-14287) on Linux or Unix-like system. Patch your systems. One can get root access by running:

    sudo -u#-1 /bin/sh
    sudo -u#4294967295 /bin/sh

    Experts discovered a security policy bypass issue in the Sudo utility that is installed as a command on almost every Linux and Unix system.

    The Sudo utility that is installed as a command on almost every Linux and Unix system is affected by a security policy bypass issue tracked as CVE-2019-14287.

    The vulnerability could be exploited by an ill-intentioned user or a malicious program to execute arbitrary commands as root on a targeted Linux system, even if the “sudoers configuration” disallows the root access.

    “When sudo is configured to allow a user to run commands as an arbitrary user via the ALL keyword in a Runas specification, it is possible to run commands as root by specifying the user ID -1 or 4294967295.” reads the security advisory.

    More than 350 ethical hackers got together in cities across Australia on Friday for a hackathon in which they worked to “cyber trace a missing face”, in the first-ever capture the flag event devoted to finding missing persons.

    Organizers called the results “astounding,” ABC News reports.

    During the six hours the competing teams hammered away at the task of searching for clues that could potentially solve 12 of the country’s most frustrating cold cases. 100 leads were generated every 10 minutes.

    Invisible mask: practical attacks on face recognition with infrared

    As a result, the adversary masquerading as someone else will be able to walk on the street, without any noticeable anomaly to other individuals but appearing to be a completely different person to the FR (facial recognition) system behind surveillance cameras.

    There are two levels of invisible mask attacks: subverting surveillance systems such that your face will not be recognised, and deliberately impersonating another individual to pass authentication tests. The authors achieved a 100% success rate at avoiding recognition, and a 70% success rate in impersonating a target individual!

    When Trump Phones Friends, the Chinese and the Russians Listen and Learn

    President Trump has two official iPhones that have limited abilities and a third that is no different from hundreds of millions of iPhones in use around the world.

    When President Trump calls old friends on one of his iPhones to gossip, gripe or solicit their latest take on how he is doing, American intelligence reports indicate that Chinese spies are often listening — and putting to use invaluable insights into how to best work the president and affect administration policy, current and former American officials said.

    Mum Discovers eBay Samsung Screen Protector Lets Anyone Open Her Phone

    Lisa Neilson, 34, said she bought a £2.70 screen protector online to cover her new Samsung Galaxy S10.

    However, later she found that her left thumb print also unlocked the phone – and soon discovered any print could do so, worryingly.

    Samsung has now launched an investigation into what happened, having advised that people should only use authorised screen protectors.

    Lisa, from Castleford, West Yorkshire, said: “Anyone can access it and could get into the financial apps and transfer funds.”
