Finding the Location of Telegram Users
Security researcher Ahmed Hassan has shown that spoofing the Android’s “People Nearby” feature allows him to pinpoint the physical location of Telegram users:
Using readily available software and a rooted Android device, he’s able to spoof the location his device reports to Telegram servers. By using just three different locations and measuring the corresponding distance reported by People Nearby, he is able to pinpoint a user’s precise location.
[…]
A proof-of-concept video the researcher sent to Telegram showed how he could discern the address of a People Nearby user when he used a free GPS spoofing app to make his phone report just three different locations. He then drew a circle around each of the three locations with a radius of the distance reported by Telegram. The user’s precise location was where all three intersected…

On US Capitol Security — By Someone Who Manages Arena-Rock-Concert Security
Smart commentary:
…I was floored on Wednesday when, glued to my television, I saw police in some areas of the U.S. Capitol using little more than those same mobile gates I had the ones that look like bike racks that can hook together to try to keep the crowds away from sensitive areas and, later, push back people intent on accessing the grounds. (A new fence that appears to be made of sturdier material was being erected on Thursday.) That’s the same equipment and approximately the same amount of force I was able to use when a group of fans got a little feisty and tried to get backstage at a Vanilla Ice show…
Microsoft Patch Tuesday, January 2021 Edition
Microsoft today released updates to plug more than 80 security holes in its Windows operating systems and other software, including one that is actively being exploited and another which was disclosed prior to today. Ten of the flaws earned Microsoft’s most-dire “critical” rating, meaning they could be exploited by malware or miscreants to seize remote control over unpatched systems with little or no interaction from Windows users.
SolarWinds: What Hit Us Could Hit Others
New research into the malware that set the stage for the megabreach at IT vendor SolarWinds shows the perpetrators spent months inside the company’s software development labs honing their attack before inserting malicious code into updates that SolarWinds then shipped to thousands of customers. More worrisome, the research suggests the insidious methods used by the intruders to subvert the company’s software development pipeline could be repurposed against many other major software providers.
Cloning Google Titan 2FA keys
This is a clever side-channel attack:
The cloning works by using a hot air gun and a scalpel to remove the plastic key casing and expose the NXP A700X chip, which acts as a secure element that stores the cryptographic secrets. Next, an attacker connects the chip to hardware and software that take measurements as the key is being used to authenticate on an existing account. Once the measurement-taking is finished, the attacker seals the chip in a new casing and returns it to the victim.
Extracting and later resealing the chip takes about four hours. It takes another six hours to take measurements for each account the attacker wants to hack. In other words, the process would take 10 hours to clone the key for a single account, 16 hours to clone a key for two accounts, and 22 hours for three accounts…
Ubiquiti: Change Your Password, Enable 2FA
Ubiquiti, a major vendor of cloud-enabled Internet of Things (IoT) devices such as routers, network video recorders, security cameras and access control systems, is urging customers to change their passwords and enable multi-factor authentication. The company says an incident at a third-party cloud provider may have exposed customer account information and credentials used to remotely manage Ubiquiti gear.
Changes in WhatsApp’s Privacy Policy
If you’re a WhatsApp user, pay attention to the changes in the privacy policy that you’re being forced to agree with.
In 2016, WhatsApp gave users a one-time ability to opt out of having account data turned over to Facebook. Now, an updated privacy policy is changing that. Come next month, users will no longer have that choice. Some of the data that WhatsApp collects includes:
- User phone numbers
- Other people’s phone numbers stored in address books
- Profile names
- Profile pictures and
- Status message including when a user was last online
- Diagnostic data collected from app logs…
Friday Squid Blogging: Searching for Giant Squid by Collecting Environmental DNA
The idea is to collect and analyze random DNA floating around the ocean, and using that to figure out where the giant squid are. No one is sure if this will actually work.
As usual, you can also use this squid post to talk about the security stories in…
