Live Coronavirus Map Used to Spread Malware

March 12, 2020

Cybercriminals constantly latch on to news items that captivate the public’s attention, but usually they do so by sensationalizing the topic or spreading misinformation about it. Recently, however, cybercrooks have started disseminating real-time, accurate information about global infection rates tied to the Coronavirus/COVID-19 pandemic in a bid to infect computers with malicious software. 

Crafty Web Skimming Domain Spoofs “https”

March 11, 2020

Earlier today, KrebsOnSecurity alerted the 10th largest food distributor in the United States that one of its Web sites had been hacked and retrofitted with code that steals credit card and login data. While such Web site card skimming attacks are not new, this intrusion leveraged a sneaky new domain that hides quite easily in a hacked site’s source code: “http[.]ps” (the actual malicious domain does not include the brackets, which are there to keep readers from being able to click on it).

FBI Arrests Alleged Owner of Deer.io, a Top Broker of Stolen Accounts

March 10, 2020

FBI officials last week arrested a Russian computer security researcher on suspicion of operating deer.io, a vast marketplace for buying and selling stolen account credentials for thousands of popular online services and stores.

Kirill V. Firsov was arrested Mar. 7 after arriving at New York’s John F. Kennedy Airport, according to court documents unsealed Monday. Prosecutors with the U.S. District Court for the Southern District of California allege Firsov was the administrator of deer.io, an online platform that hosted more than 24,000 shops for selling stolen and/or hacked usernames and passwords for a variety of top online destinations.

U.S. Govt. Makes it Harder to Get .Gov Domains

March 7, 2020

The federal agency in charge of issuing .gov domain names is enacting new requirements for validating the identity of people requesting them. The additional measures come less than four months after KrebsOnSecurity published research suggesting it was relatively easy for just about anyone to get their very own .gov domain.

In November’s piece It’s Way Too Easy to Get a .gov Domain Name, an anonymous source detailed how he obtained one by impersonating an official at a small town in Rhode Island that didn’t already have its own .gov.

The Case for Limiting Your Browser Extensions

March 3, 2020

Last week, KrebsOnSecurity reported to health insurance provider Blue Shield of California that its Web site was flagged by multiple security products as serving malicious content. Blue Shield quickly removed the unauthorized code. An investigation determined it was injected by a browser extension installed on the computer of a Blue Shield employee who’d edited the Web site in the past month.

The incident is a reminder that browser extensions — however useful or fun they may seem when you install them — typically have a great deal of power and can effectively read and/or write all data in your browsing sessions. And as we’ll see, it’s not uncommon for extension makers to sell or lease their user base to shady advertising firms, or in some cases abandon them to outright cybercriminals.

French Firms Rocked by Kasbah Hacker?

March 2, 2020

A large number of French critical infrastructure firms were hacked as part of an extended malware campaign that appears to have been orchestrated by at least one attacker based in Morocco, KrebsOnSecurity has learned. The individual thought to be involved has earned accolades from the likes of Apple, Dell, and Microsoft for helping to find and fix security vulnerabilities in their products.

FCC Proposes to Fine Wireless Carriers $200M for Selling Customer Location Data

February 28, 2020

The U.S. Federal Communications Commission (FCC) today proposed fines of more than $200 million against the nation’s four largest wireless carriers for selling access to their customers’ location information without taking adequate precautions to prevent unauthorized access to that data. While the fines would be among the largest the FCC has ever levied, critics say the penalties don’t go far enough to deter wireless carriers from continuing to sell customer location data.

Zyxel Fixes 0day in Network Storage Devices

February 24, 2020

Networking hardware vendor Zyxel today released an update to fix a critical flaw in many of its network attached storage (NAS) devices that can be used to remotely commandeer them. The patch comes 12 days after KrebsOnSecurity alerted the company that precise instructions for exploiting the vulnerability were being sold for $20,000 in the cybercrime underground.

Based in Taiwan, Zyxel Communications Corp. (a.k.a “ZyXEL”) is a maker of networking devices, including Wi-Fi routers, NAS products and hardware firewalls. The company has roughly 1,500 employees and boasts some 100 million devices deployed worldwide. While in many respects the class of vulnerability addressed in this story is depressingly common among Internet of Things (IoT) devices, the flaw is notable because it has attracted the interest of groups specializing in deploying ransomware at scale.
