Senators Prod FCC to Act on SIM Swapping

Crooks have stolen tens of millions of dollars and other valuable commodities from thousands of consumers via “SIM swapping,” a particularly invasive form of fraud that involves tricking a target’s mobile carrier into transferring someone’s wireless service to a device they control. But the U.S. Federal Communications Commission (FCC), the entity responsible for overseeing wireless industry practices, has so far remained largely silent on the matter. Now, a cadre of Senate lawmakers is demanding to know what, if anything, the agency might be doing to track and combat SIM swapping.

New SHA-1 Attack

There’s a new, practical, collision attack against SHA-1: In this paper, we report the first practical implementation of this attack, and its impact on real-world security with a PGP/GnuPG impersonation attack. We managed to significantly reduce the complexity of collisions attack against SHA-1: on an Nvidia GTX 970, identical-prefix collisions can now be computed with a complexity of 261.2rather than264.7,…

Tricky Phish Angles for Persistence, Not Passwords

Late last year saw the re-emergence of a nasty phishing tactic that allows the attacker to gain full access to a user’s data stored in the cloud without actually stealing the account password. The phishing lure starts with a link that leads to the real login page for a cloud email and/or file storage service. Anyone who takes the bait will inadvertently forward a digital token to the attackers that gives them indefinite access to the victim’s email, files and contacts — even after the victim has changed their password.

USB Cable Kill Switch for Laptops

BusKill is designed to wipe your laptop (Linux only) if it is snatched from you in a public place: The idea is to connect the BusKill cable to your Linux laptop on one end, and to your belt, on the other end. When someone yanks your laptop from your lap or table, the USB cable disconnects from the laptop and…

The Hidden Cost of Ransomware: Wholesale Password Theft

Organizations in the throes of cleaning up after a ransomware outbreak typically will change passwords for all user accounts that have access to any email systems, servers and desktop workstations within their network. But all too often, ransomware victims fail to grasp that the crooks behind these attacks can and frequently do siphon every single password stored on each infected endpoint. The result of this oversight may offer attackers a way back into the affected organization, access to financial and healthcare accounts, or — worse yet — key tools for attacking the victim’s various business partners and clients.

Mailbox Master Keys

Here’s a physical-world example of why master keys are a bad idea. It’s a video of two postal thieves using a master key to open apartment building mailboxes. Changing the master key for physical mailboxes is a logistical nightmare, which is why this problem won’t be fixed anytime soon….

Friday Squid Blogging: Giant Squid Video from the Gulf of Mexico

Fantastic video: Scientists had used a specialized camera system developed by Widder called the Medusa, which uses red light undetectable to deep sea creatures and has allowed scientists to discover species and observe elusive ones. The probe was outfitted with a fake jellyfish that mimicked the invertebrates’ bioluminescent defense mechanism, which can signal to larger predators that a meal may…
