Security Friday: News and Pegasus – TMO Daily Observations 2021-07-23
Andrew Orr and Bryan Chaffin talk Security Friday news with host Kelly Guimont, then dig into the Pegasus story you’ve heard about this week.
Researchers Hid Malware Inside an AI’s Brain
This is straight out of a sci-fi novel. Researchers created a proof-of-concept technique that let them hide malware inside of an AI’s neurons to avoid detection.
According to the paper, in this approach the malware is “disassembled” when embedded into the network’s neurons, and assembled into functioning malware by a malicious receiver program that can also be used to download the poisoned model via an update. The malware can still be stopped if the target device verifies the model before launching it, according to the paper. It can also be detected using “traditional methods” like static and dynamic analysis.
Worried if You Were Infected by Pegasus? This Tool Can Help
This week, a strain of malware known as Pegasus from NSO Group has been making headlines. It’s used by governments to target journalists, activists, and other people deemed dissidents. But there is a tool that could detect it.
MVT will let you take an entire iPhone backup (or a full system dump if you jailbreak your phone) and feed in for any indicators of compromise (IOCs) known to be used by NSO to deliver Pegasus, such as domain names used in NSO’s infrastructure that might be sent by text message or email.
Hackers Leak ‘Humana’ Data of Over 6,000 Patients
An SQL database containing what appears to be highly sensitive health insurance data of more than 6,000 patients has been leaked on a hacker forum.
The author of the post claims that the data was acquired from US insurance giant Humana and includes detailed medical records of the company’s health plan members dating back to 2019. The leaked information includes patients’ names, IDs, email addresses, password hashes, Medicare Advantage Plan listings, medical treatment data, and more.
So What’s Up With This NSO Group Pegasus Thing Anyway?

China Allegedly Behind Microsoft Exchange Hack Revealed in March 2021
The White House has formally accused China of hacking Microsoft Exchange servers, a security campaign that was revealed in March 2021.
NSO Group’s ‘Pegasus’ Spyware Targets Journalists and Activists
Spyware known as Pegasus from NSO Group was used to hack 37 smartphones belonging to journalists, activists, and business executives around the world.
The phones appeared on a list of more than 50,000 numbers that are concentrated in countries known to engage in surveillance of their citizens and also known to have been clients of the Israeli firm, NSO Group, a worldwide leader in the growing and largely unregulated private spyware industry, the investigation found.
Security Friday: News Old and New, and Future Updates – TMO Daily Observations 2021-07-16
Andrew Orr joins host Kelly Guimont to discuss updates to previous Security Friday news, and a couple of items coming to Firefox and iOS.
Firefox 90 Update Introduces SmartBlock 2.0 for Tracking Protection
Mozilla released Firefox 90 recently and it comes with an improved version of its tracking protection called SmartBlock 2.0.
The newest version of Mozilla’s built-in SmartBlock privacy feature makes it easier for users to keep their tracking protection settings cranked up, without breaking individual websites. The updated version seems to especially target Facebook login, which is increasingly used around the web as a third-party authentication and login tool.

Google Adds Tool to Quickly Delete Your Last 15 Minutes of Searches
Google is adding new protections for your search history like quick deletion, requiring verification to access the My Activity section, and more.
You can also try out a new way to quickly delete your last 15 minutes of saved Search history with the single tap of a button. This feature is available in the Google app for iOS, and is coming to the Android Google app later this year.
You could also just turn disable your search history altogether, too.
‘SolarWinds’ Hackers Used iOS Zero Day Against Government Officials
The Russian hackers behind the SolarWinds attack used an iOS zero day to steal credentials from Western European governments.
Attacks targeting CVE-2021-1879, as the zero-day is tracked, redirected users to domains that installed malicious payloads on fully updated iPhones. The attacks coincided with a campaign by the same hackers who delivered malware to Windows users, the researchers said.
Google published a blog post about zero-days here, and you can read coverage from Ars Technica at the link below.
iOS 15: How to Add Two-Factor Authentication Codes to Passwords
A welcome feature in iOS 15 is the ability to add two-factor authentication codes to your passwords. Here’s how to set it up.
Security Friday: News on Data Privacy and a Practical PDF Tip – TMO Daily Observations 2021-07-09
Andrew Orr joins host Kelly Guimont to discuss Security Friday news and updates, including data privacy and how to encrypt a pdf on your Mac.
Over 170 Android Cryptocurrency Apps are Scams
A recent report shows that Android has a cryptocurrency scam problem. These apps claim to help you mine Bitcoin “in the cloud.”
The apps work by offering a virtual dashboard that lets you monitor the cryptocurrency mining rate. The same dashboard shows you how much virtual coin has been generated. However, Lookout examined the computer code in the apps along with the network traffic, and found the coin balance displayed was actually fictitious.
Kaspersky’s Password Manager Created Weak Passwords
Kaspersky Password Manager was caught creating weak passwords that were easy to brute force attack.
We will first see an example of a good password generation method, to explain after why the method used by Kaspersky was flawed, and how we exploited it. As we will see, passwords generated by this tool can be bruteforced in seconds.
After a bit less than two years, this vulnerability has been patched on all versions of KPM. Vulnerability has been assigned CVE-2020-27020.
New Ransomware ‘Tsunami’ Destroying Supply Chains
The REvil hacking team is back with new malware. Brand new, still developing, but their ransomware called “Tsunami” is wreaking havoc.
The software in question, Kaseya VSA, is popular among so-called managed service providers, which provide IT infrastructure for companies that would rather outsource that sort of thing than run it themselves. Which means that if you successfully hack an MSP, you suddenly have access to its customers. It’s the difference between cracking safety deposit boxes one at a time and stealing the bank manager’s skeleton key.
Europe Chief Tells Apple Not to Use Privacy to Limit Competition
Margrethe Vestager, the European Commission’s VP for technology, says that Apple shouldn’t use privacy and security to limit competitors.
Russian Spies Abuse VPNs to Target Organizations
On Thursday, U.S. and British authorities said that Russia’s military spy agency is using VPNs and Tor to attack governments and private sector targets.
The advisory did not identify any of the targets by name, saying only that they were mainly in the United States and Europe and included government offices, political parties, energy companies, law firms and media organizations.
The Russian Embassy in Washington did not immediately return a message seeking comment. Russian officials routinely reject allegations that they employ hackers to spy on rival nations.
Twitter Lets You Use a Security Key as Only 2FA Option
Twitter announced on Wednesday that it will let people use a security key as their only form of two-factor authentication.
Today, we’re adding the option to use security keys as your sole 2FA method — meaning you can enroll one or more security keys as the only form of 2FA on your Twitter account without a backup 2FA method. We know this is important to people because not everyone is able to have a backup 2FA method or wants to share their phone number with us.
Cryptomator’s Major 2.0 Upgrade is Available in TestFlight, Now Open Source
File encryption app Cryptomator is readying a major 2.0 upgrade and interested users can test the beta within Apple’s TestFlight app on iOS.

Security Friday: Data Breaches and Password Migration – TMO Daily Observations 2021-06-25
Andrew Orr joins host Kelly Guimont for Security Friday news and updates, including a massive data breach, and how to import/export passwords.
Web Hosting Service 'DreamHost' Leaked 814 Million Records of Customer Data
A database owned by Dreamhost was found unsecured and publicly accessible online. It contained 814 million entries of exposed usernames, display names, and emails for WordPress accounts.
The exposed log files contained what appears to be 3 years of records that range from 3/24/2018 to 4/16/2021 and each contained information about WordPress accounts hosted or installed on DreamHost’s server and their users. On May 4th a DreamHost representative acknowledged the discovery and informed us that the finding was being passed on to their legal team.
Update: DreamHost reached out to say that none of those records contain data that would have allowed access to DreamHost accounts. They consist entirely of entries that include object update records, error reports, and log entries. Data from just 21 individual websites were involved. More information can be found on its website.
