BitDefender bit trip slaps 'valid' on revoked certs

Patch for security suites inbound


Bitdefender is set to fix a security flaw in its products that meant revoked certificates for potentially malicious sites could be replaced with legitimate ones.

The problem, which the security vendor considered a low-level threat, arose when revoked certificates were replaced with a BitDefender certificate for the purpose of scanning HTTPS traffic.

That meant admins of potentially dodgy sites could be given a means of attacking users.

The Chief Research Officer of Risk Based Security, Carsten Eiram, reported the flaws in BitDefender's Antivirus Plus, Internet Security, and Total Security lines which are set to be fixed this week.

“HTTPS scanning issues are something that a lot of people are focusing on,” Eiram told the IDG News Service.

“Someone is bound to download and check certificate validation in various security products including BitDefender.

“It’s just a matter of downloading the product and then visiting a site with a revoked certificate to see the unsafe behaviour.”

BitDefender's slip was light years from the dangers posed by the privacy-annihilating SuperFish interception kit or the borked PrivDog HTTPS fondler which prompted anger from privacy and security types over the last fortnight.

Its platforms replace HTTPS certificates to ensure a given site is legitimate. It first checks that a certificate is listed for the correct site and that is not expired, but failed to look for revocation status.

Eiram said feasible attacks include ARP spoofing, DNS hijacking, and evil twin WiFi attacks which can allow attackers to steal a victim's authentication tokens.

He says it it would be easy for attackers to test if other security platforms were meddling with certificate revocation checking using online services.

In July researcher Stefan Viehbock found since fixed holes in BitDefender's Gravity end-point protection platform that allow hackers to target corporate infrastructure allowing attackers to move laterally through a network. ®

    In-brief Governments around the world should pass intellectual property laws that grant rights to AI systems, two academics at the University of New South Wales in Australia argued.

    Alexandra George, and Toby Walsh, professors of law and AI, respectively, believe failing to recognize machines as inventors could have long-lasting impacts on economies and societies. 

    "If courts and governments decide that AI-made inventions cannot be patented, the implications could be huge," they wrote in a comment article published in Nature. "Funders and businesses would be less incentivized to pursue useful research using AI inventors when a return on their investment could be limited. Society could miss out on the development of worthwhile and life-saving inventions."

    More papers describing the orders and messages the US President can issue in the event of apocalyptic crises, such as a devastating nuclear attack, have been declassified and released for all to see.

    These government files are part of a larger collection of records that discuss the nature, reach, and use of secret Presidential Emergency Action Documents: these are executive orders, announcements, and statements to Congress that are all ready to sign and send out as soon as a doomsday scenario occurs. PEADs are supposed to give America's commander-in-chief immediate extraordinary powers to overcome extraordinary events.

    PEADs have never been declassified or revealed before. They remain hush-hush, and their exact details are not publicly known.

  • Stolen university credentials up for sale by Russian crooks, FBI warns
    Forget dark-web souks, thousands of these are already being traded on public bazaars

    Russian crooks are selling network credentials and virtual private network access for a "multitude" of US universities and colleges on criminal marketplaces, according to the FBI.

    According to a warning issued on Thursday, these stolen credentials sell for thousands of dollars on both dark web and public internet forums, and could lead to subsequent cyberattacks against individual employees or the schools themselves.

    "The exposure of usernames and passwords can lead to brute force credential stuffing computer network attacks, whereby attackers attempt logins across various internet sites or exploit them for subsequent cyber attacks as criminal actors take advantage of users recycling the same credentials across multiple accounts, internet sites, and services," the Feds' alert [PDF] said.
