Former New York City Mayor Rudolph W. Giuliani has been appointed as a cyber security advisor for the President-elect Donald Trump, but it appears that he never actually checked the security defenses of his own company's website. Giuliani is going to head a new Cybersecurity Working group for the President-elect, and "will be sharing his expertise and insight as a trusted friend concerning private sector cyber security problems and emerging solutions developing in the private sector," the Trump's Transition Team announced Thursday. Trump administration has appointed Giuliani after citing his 16 years of experience "providing security solutions in the private sector," but the news met online criticism with many users on Twitter asking: 'What does the former New York mayor know about cyber security?' As the news broke, online users started scanning his website " www.giulianisecurity.com " and found that the site for Giuliani Sec...

With just two days before the presidential election, WikiLeaks late Sunday night published a new trove of emails apparently hacked from the Democratic National Committee (DNC). The most recent dump of more than 8,000 emails came after the whistleblowing site, on a daily basis over last four weeks, has already leaked over 50,000 emails stolen from the key figure in the DNC – Hillary Clinton's campaign chairman John Podesta. However, this time, not everything went as planned by WikiLeaks. WikiLeaks early Monday morning announced on Twitter that shortly after the release of hacked DNC emails the organization was the target of a major Distributed Denial of Service (DDoS) attack. What's more?  Soon after WikiLeaks reported the DDoS attack on its email publication servers, Twitter also went down, and the outage lasts for at least 30 minutes. According to a status monitor, the Twitter outage began at around 6.45am GMT and continued for nearly half an hour, though report...

The hacker, known as Guccifer , targeted several e-mail accounts and exposed personal photos and sensitive correspondence from members of the former US President Bush family, including both former U.S. presidents. Hacked Emails includes the AOL account of his daughter Dorothy Bush Koch; family friends Willard Hemingway and Jim Nantz; former First Lady Barbara Bush's brother; and George H W Bush's sister-in-law. Some of the e-mails contain catty comments about another former president, Bill Clinton. The photos and e-mails were uploaded yesterday to an online account that appears to have been hacked for the purpose of hosting the material including confidential October 2012 list of home addresses, cell phone numbers, and e-mails for dozens of Bush family members, including both former presidents, their siblings, and their children. The hacker also intercepted photos that George W. Bush e-mailed two months ago to his sister showing paintings that he was working o...

If you invite guest users into your Entra ID tenant, you may be opening yourself up to a surprising risk.  A gap in access control in Microsoft Entra's subscription handling is allowing guest users to create and transfer subscriptions into the tenant they are invited into, while maintaining full ownership of them.  All the guest user needs are the permissions to create subscriptions in their home tenant, and an invitation as a guest user into an external tenant. Once inside, the guest user can create subscriptions in their home tenant, transfer them into the external tenant, and retain full ownership rights. This stealthy privilege escalation tactic allows a guest user to gain a privileged foothold in an environment where they should only have limited access. Many organizations treat guest accounts as low-risk based on their temporary, limited access, but this behavior, which works as designed, opens the door to known attack paths and lateral movement within the resource t...
