For whatever reason, the majority of the phony LinkedIn profiles reviewed by this author have involved young women with profile photos that appear to be generated by artificial intelligence (AI) tools.
We’re seeing rapid advances in AI-based synthetic image generation technology and we’ve created a deep learning model to better catch profiles made with this technology. AI-based image generators can create an unlimited number of unique, high-quality profile photos that do not correspond to real people. Fake accounts sometimes use these convincing, AI-generated profile photos to make their fake LinkedIn profile appear more authentic.
On October 10, 2022, there were 576,562 LinkedIn accounts that listed their current employer as Apple Inc. The next day, half of those profiles no longer existed. A similarly dramatic drop in the number of LinkedIn profiles claiming employment at Amazon comes as LinkedIn is struggling to combat a significant uptick in the creation of fake employee accounts that pair AI-generated profile photos with text lifted from legitimate users.
Apple, Google and Microsoft announced this week they will soon support an approach to authentication that avoids passwords altogether, and instead requires users to merely unlock their smartphones to sign in to websites or online services. Experts say the changes should help defeat many types of phishing attacks and ease the overall password burden on Internet users, but caution that a true passwordless future may still be years away for most websites.
When KrebsOnSecurity last month explored how cybercriminals were using hacked email accounts at police departments worldwide to obtain warrantless Emergency Data Requests (EDRs) from social media and technology providers, many security experts called it a fundamentally unfixable problem. But don’t tell that to Matt Donahue, a former FBI agent who recently quit the agency to launch a startup that aims to help tech companies do a better job screening out phony law enforcement data requests — in part by assigning trustworthiness or “credit ratings” to law enforcement authorities worldwide.
KrebsOnSecurity recently reviewed a copy of the private chat messages between members of the LAPSUS$ cybercrime group in the week leading up to the arrest of its most active members last month. The logs show LAPSUS$ breached T-Mobile multiple times in March, stealing source code for a range of company projects. T-Mobile says no customer or government information was stolen in the intrusion.
LAPSUS$ is known for stealing data and then demanding a ransom not to publish or sell it. But the leaked chats indicate this mercenary activity was of little interest to the tyrannical teenage leader of LAPSUS$, whose obsession with stealing and leaking proprietary computer source code from the world’s largest tech companies ultimately led to the group’s undoing.
On Tuesday, KrebsOnSecurity warned that hackers increasingly are using compromised government and police department email accounts to obtain sensitive customer data from mobile providers, ISPs and social media companies. Today, one of the U.S. Senate’s most tech-savvy lawmakers said he was troubled by the report and is now asking technology companies and federal agencies for information about the frequency of such schemes.
Microsoft today issued updates to plug more than 70 security holes in its Windows operating systems and other software, including one vulnerability that is already being exploited in active attacks. This month’s Patch Tuesday also includes security fixes for the newly released Windows 11 operating system.
Microsoft today pushed software updates to plug dozens of security holes in Windows and related products, including a vulnerability that is already being exploited in active attacks. Also, Apple has issued an emergency update to fix a flaw that’s reportedly been abused to install spyware on iOS products, and Google’s got a new version of Chrome that tackles two zero-day flaws. Finally, Adobe has released critical security updates for Acrobat, Reader and a slew of other software.
Apple is rolling out a new update to its iOS operating system that addresses the location privacy issue on iPhone 11 devices that was first detailed here last month.
KrebsOnSecurity ran a story this week that puzzled over Apple’s response to inquiries about a potential privacy leak in its new iPhone 11 line, in which the devices appear to intermittently seek the user’s location even when all applications and system services are individually set never to request this data. Today, Apple disclosed that this behavior is tied to the inclusion of a new short-range technology that lets iPhone 11 users share files locally with other nearby phones that support this feature, and that a future version of its mobile operating system will allow users to disable it.
