A Peek into the Fake Review Marketplace

A personal account of someone who was paid to buy products on Amazon and leave fake reviews.

Fake reviews are one of the problems that everyone knows about, and no one knows what to do about -- so we all try to pretend doesn't exist.

Friday Squid Blogging: China Closing Its Squid Spawning Grounds

China is prohibiting squid fishing in two areas -- both in international waters -- for two seasons, to give squid time to recover and reproduce.

This is the first time China has voluntarily imposed a closed season on the high seas. Some experts regard it as an important step forward in China's management of distant-water fishing (DWF), and crucial for protecting the squid fishing industry. But others say the impact will be limited and that stronger oversight of fishing vessels is needed, or even a new fisheries management body specifically for squid.

As usual, you can also use this squid post to talk about the security stories in the news that I haven't covered.

Business Email Compromise (BEC) Criminal Ring

A criminal group called Cosmic Lynx seems to be based in Russia:

Dubbed Cosmic Lynx, the group has carried out more than 200 BEC campaigns since July 2019, according to researchers from the email security firm Agari, particularly targeting senior executives at large organizations and corporations in 46 countries. Cosmic Lynx specializes in topical, tailored scams related to mergers and acquisitions; the group typically requests hundreds of thousands or even millions of dollars as part of its hustles.

[...]

For example, rather than use free accounts, Cosmic Lynx will register strategic domain names for each BEC campaign to create more convincing email accounts. And the group knows how to shield these domains so they're harder to trace to the true owner. Cosmic Lynx also has a strong understanding of the email authentication protocol DMARC and does reconnaissance to assess its targets' specific system DMARC policies to most effectively circumvent them.

Cosmic Lynx also drafts unusually clean and credible-looking messages to deceive targets. The group will find a company that is about to complete an acquisition and contact one of its top executives posing as the CEO of the organization being bought. This phony CEO will then involve "external legal counsel" to facilitate the necessary payments. This is where Cosmic Lynx adds a second persona to give the process an air of legitimacy, typically impersonating a real lawyer from a well-regarded law firm in the United Kingdom. The fake lawyer will email the same executive that the "CEO" wrote to, often in a new email thread, and share logistics about completing the transaction. Unlike most BEC campaigns, in which the messages often have grammatical mistakes or awkward wording, Cosmic Lynx messages are almost always clean.

Traffic Analysis of Home Security Cameras

Interesting research on home security cameras with cloud storage. Basically, attackers can learn very basic information about what's going on in front of the camera, and infer when there is someone home.

News article.

Half a Million IoT Passwords Leaked

It is amazing that this sort of thing can still happen:

...the list was compiled by scanning the entire internet for devices that were exposing their Telnet port. The hacker then tried using (1) factory-set default usernames and passwords, or (2) custom, but easy-to-guess password combinations.

Telnet? Default passwords? In 2020?

We have a long way to go to secure the IoT.

IoT Security Principles

The BSA -- also known as the Software Alliance, formerly the Business Software Alliance (which explains the acronym) -- is an industry lobbying group. They just published "Policy Principles for Building a Secure and Trustworthy Internet of Things."

They call for:

  • Distinguishing between consumer and industrial IoT.
  • Offering incentives for integrating security.
  • Harmonizing national and international policies.
  • Establishing regularly updated baseline security requirements

As with pretty much everything else, you can assume that if an industry lobbying group is in favor of it, then it doesn't go far enough.

And if you need more security and privacy principles for the IoT, here's a list of over twenty.

ThiefQuest Ransomware for the Mac

There's a new ransomware for the Mac called ThiefQuest or EvilQuest. It's hard to get infected:

For your Mac to become infected, you would need to torrent a compromised installer and then dismiss a series of warnings from Apple in order to run it. It's a good reminder to get your software from trustworthy sources, like developers whose code is "signed" by Apple to prove its legitimacy, or from Apple's App Store itself. But if you're someone who already torrents programs and is used to ignoring Apple's flags, ThiefQuest illustrates the risks of that approach.

But it's nasty:

In addition to ransomware, ThiefQuest has a whole other set of spyware capabilities that allow it to exfiltrate files from an infected computer, search the system for passwords and cryptocurrency wallet data, and run a robust keylogger to grab passwords, credit card numbers, or other financial information as a user types it in. The spyware component also lurks persistently as a backdoor on infected devices, meaning it sticks around even after a computer reboots, and could be used as a launchpad for additional, or "second stage," attacks. Given that ransomware is so rare on Macs to begin with, this one-two punch is especially noteworthy.
