Fraudulent Tactics on Amazon Marketplace

Fascinating article about the many ways Amazon Marketplace sellers sabotage each other and defraud customers. The opening example: framing a seller for false advertising by buying fake five-star reviews for their products.

Defacement: Sellers armed with the accounts of Amazon distributors (sometimes legitimately, sometimes through the black market) can make all manner of changes to a rival’s listings, from changing images to altering text to reclassifying a product into an irrelevant category, like “sex toys.”

Phony fires: Sellers will buy their rival’s product, light it on fire, and post a picture to the reviews, claiming it exploded. Amazon is quick to suspend sellers for safety claims.

Over the following days, Harris came to realize that someone had been targeting him for almost a year, preparing an intricate trap. While he had trademarked his watch and registered his brand, Dead End Survival, with Amazon, Harris hadn’t trademarked the name of his Amazon seller account, SharpSurvival. So the interloper did just that, submitting to the patent office as evidence that he owned the goods a photo taken from Harris’ Amazon listings, including one of Harris’ own hands lighting a fire using the clasp of his survival watch. The hijacker then took that trademark to Amazon and registered it, giving him the power to kick Harris off his own listings and commandeer his name.

There are more subtle methods of sabotage as well. Sellers will sometimes buy Google ads for their competitors for unrelated products—say, a dog food ad linking to a shampoo listing—so that Amazon’s algorithm sees the rate of clicks converting to sales drop and automatically demotes their product.

What’s also interesting is how Amazon is basically its own government—with its own rules that its suppliers have no choice but to follow. And, of course, increasingly there is no option but to sell your stuff on Amazon.

Congressional Report on the 2017 Equifax Data Breach

The US House of Representatives Committee on Oversight and Government Reform has just released a comprehensive report on the 2017 Equifax hack. It’s a great piece of writing, with a detailed timeline, root cause analysis, and lessons learned. Lance Spitzner also commented on this.

Here is my testimony before before the House Subcommittee on Digital Commerce and Consumer Protection last November.

New Shamoon Variant

A new variant of the Shamoon malware has destroyed significant amounts of data at a UAE “heavy engineering company” and the Italian oil and gas contractor Saipem.

Shamoon is the Iranian malware that was targeted against the Saudi Arabian oil company, Saudi Aramco, in 2012 and 2016. We have no idea if this new variant is also Iranian in origin, or if it is someone else entirely using the old Iranian code base.

Real-Time Attacks Against Two-Factor Authentication

Attackers are targeting two-factor authentication systems:

Attackers working on behalf of the Iranian government collected detailed information on targets and used that knowledge to write spear-phishing emails that were tailored to the targets’ level of operational security, researchers with security firm Certfa Lab said in a blog post. The emails contained a hidden image that alerted the attackers in real time when targets viewed the messages. When targets entered passwords into a fake Gmail or Yahoo security page, the attackers would almost simultaneously enter the credentials into a real login page. In the event targets’ accounts were protected by 2fa, the attackers redirected targets to a new page that requested a one-time password.

This isn’t new. I wrote about this exact attack in 2005 and 2009.

Marriott Hack Reported as Chinese State-Sponsored

The New York Times and Reuters are reporting that China was behind the recent hack of Marriott Hotels. Note that this is still uncomfirmed, but interesting if it is true.

Reuters:

Private investigators looking into the breach have found hacking tools, techniques and procedures previously used in attacks attributed to Chinese hackers, said three sources who were not authorized to discuss the company’s private probe into the attack.

That suggests that Chinese hackers may have been behind a campaign designed to collect information for use in Beijing’s espionage efforts and not for financial gain, two of the sources said.

While China has emerged as the lead suspect in the case, the sources cautioned it was possible somebody else was behind the hack because other parties had access to the same hacking tools, some of which have previously been posted online.

Identifying the culprit is further complicated by the fact that investigators suspect multiple hacking groups may have simultaneously been inside Starwood’s computer networks since 2014, said one of the sources.

I used to have opinions about whether these attributions are true or not. These days, I tend to wait and see.

New Australian Backdoor Law

Last week, Australia passed a law giving the government the ability to demand backdoors in computers and communications systems. Details are still to be defined, but it’s really bad.

Note: Many people e-mailed me to ask why I haven’t blogged this yet. One, I was busy with other things. And two, there’s nothing I can say that I haven’t said many times before.

If there are more good links or commentary, please post them in the comments.

EDITED TO ADD (12/13): The Australian government response is kind of embarrassing.
