The U.S. Justice Department on Tuesday unsealed the guilty pleas of two men first identified in January 2017 by KrebsOnSecurity as the likely co-authors of Mirai, a malware strain that remotely enslaves so-called “Internet of Things” devices such as security cameras, routers, and digital video recorders for use in large scale attacks designed to knock Web sites and entire networks offline (including multiple major attacks against this site).

Phishers Are Upping Their Game. So Should You.

Not long ago, phishing attacks were fairly easy for the average Internet user to spot: Full of grammatical and spelling errors, and linking to phony bank or email logins at unencrypted (http:// vs. https://) Web pages. Increasingly, however, phishers are upping their game, polishing their copy and hosting scam pages over https:// connections — complete with the green lock icon in the browser address bar to make the fake sites appear more legitimate.

Anti-Skimmer Detector for Skimmer Scammers

Crooks who make and deploy ATM skimmers are constantly engaged in a cat-and-mouse game with financial institutions, which deploy a variety of technological measures designed to defeat skimming devices.

Roman Seleznev, a Russian man who is already serving a record 27-year sentence in the United States for cybercrime charges, was handed a 14-year sentence this week by a federal judge in Atlanta for his role in a credit card and identity theft conspiracy that prosecutors say netted more than $50 million.

MacOS High Sierra Users: Change Root Password Now

A newly-discovered flaw in macOS High Sierra — Apple’s latest iteration of its operating system — allows anyone with local (and, apparently in some cases, remote) access to the machine to log in as the all-powerful “root” user without supplying a password. Fortunately, there is a simple fix for this until Apple patches this inexplicable bug: Change the root account’s password now.

Who Was the NSA Contractor Arrested for Leaking the ‘Shadow Brokers’ Hacking Tools?

In August 2016, a mysterious entity calling itself “The Shadow Brokers” began releasing the first of several troves of classified documents and hacking tools purportedly stolen from “The Equation Group,” a highly advanced threat actor that is suspected of having ties to the U.S. National Security Agency. According to media reports, at least some of the information was stolen from the computer of an unidentified software developer and NSA contractor who was arrested in 2015 after taking the hacking tools home. In this post, we’ll examine clues left behind in the leaked Equation Group documents that may point to the identity of the mysterious software developer.

Name+DOB+SSN=FAFSA Data Gold Mine

KrebsOnSecurity has sought to call attention to online services which expose sensitive consumer data if the user knows a handful of static details about a person that are broadly for sale in the cybercrime underground, such as name, date of birth, and Social Security Number. Perhaps the most eye-opening example of this is on display at fafsa.ed.gov, the Web site set up by the U.S. Department of Education for anyone interested in applying for federal student financial aid.
