Your Phone May Soon Replace Many of Your Passwords

May 7, 2022

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.

Fighting Fake EDRs With ‘Credit Ratings’ for Police

April 27, 2022

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.

Leaked Chats Show LAPSUS$ Stole T-Mobile Source Code

April 22, 2022

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.

Conti’s Ransomware Toll on the Healthcare Industry

April 18, 2022

Conti — one of the most ruthless and successful Russian ransomware groups — publicly declared during the height of the COVID-19 pandemic that it would refrain from targeting healthcare providers. But new information confirms this pledge was always a lie, and that Conti has launched more than 200 attacks against hospitals and other healthcare facilities since first surfacing in 2018 under the name “Ryuk.”

The Original APT: Advanced Persistent Teenagers

April 6, 2022

Many organizations are already struggling to combat cybersecurity threats from ransomware purveyors and state-sponsored hacking groups, both of which tend to take days or weeks to pivot from an opportunistic malware infection to a full blown data breach. But few organizations have a playbook for responding to the kinds of virtual “smash and grab” attacks we’ve seen recently from LAPSUS$, a juvenile data extortion group whose short-lived, low-tech and remarkably effective tactics are putting some of the world’s biggest corporations on edge.

Hackers Gaining Power of Subpoena Via Fake “Emergency Data Requests”

March 29, 2022

There is a terrifying and highly effective “method” that criminal hackers are now using to harvest sensitive customer data from Internet service providers, phone companies and social media firms. It involves compromising email accounts and websites tied to police departments and government agencies, and then sending unauthorized demands for subscriber data while claiming the information being requested can’t wait for a court order because it relates to an urgent matter of life and death.

A Closer Look at the LAPSUS$ Data Extortion Group

March 23, 2022

Microsoft and identity management platform Okta both disclosed this week breaches involving LAPSUS$, a relatively new cybercrime group that specializes in stealing data from big companies and threatening to publish the information unless a ransom demand is paid. Here’s a closer look at LAPSUS$, and some of the low-tech but high-impact methods the group uses to gain access to targeted organizations.

How Phishers Are Slinking Their Links Into LinkedIn

February 3, 2022

If you received a link to LinkedIn.com via email, SMS or instant message, would you click it? Spammers, phishers and other ne’er-do-wells are hoping you will, because they’ve long taken advantage of a marketing feature on the business networking site which lets them create a LinkedIn.com link that bounces your browser to other websites, such as phishing pages that mimic top online brands (but chiefly Linkedin’s parent firm Microsoft).

Microsoft Patch Tuesday, December 2021 Edition

December 14, 2021

Microsoft, Adobe, and Google all issued security updates to their products today. The Microsoft patches include six previously disclosed security flaws, and one that that is already being actively exploited. But this month’s Patch Tuesday is being overshadowed by the “Log4Shell” 0-day exploit in a popular Java library that web server administrators are now racing to find and patch amid widespread exploitation of the flaw.

Microsoft Corp. warned Tuesday that attackers are exploiting a previously unknown vulnerability in Windows 10 and many Windows Server versions to seize control over PCs when users open a malicious document or visit a booby-trapped website. There is currently no official patch for the flaw, but Microsoft has released recommendations for mitigating the threat.
