The U.S. Drug Enforcement Administration (DEA) says it is investigating reports that hackers gained unauthorized access to an agency portal that taps into 16 different federal law enforcement databases. KrebsOnSecurity has learned the alleged compromise is tied to a cybercrime and online harassment community that routinely impersonates police and government officials to harvest personal information on their targets.
The CEO of a South Carolina technology firm has pleaded guilty to 20 counts of wire fraud in connection with an elaborate network of phony companies set up to obtain more than 735,000 Internet Protocol (IP) addresses from the nonprofit organization that leases the digital real estate to entities in North America.
A California company that helps telemarketing firms avoid getting sued for violating a federal law that seeks to curb robocalls has leaked the phone numbers, email addresses and passwords of all its customers, as well as the mobile phone numbers and other data on people who have hired lawyers to go after telemarketers.
Federal prosecutors in California have filed criminal charges against four employees of Adconion Direct, an email advertising firm, alleging they unlawfully hijacked vast swaths of Internet addresses and used them in large-scale spam campaigns. KrebsOnSecurity has learned that the charges are likely just the opening salvo in a much larger, ongoing federal investigation into the company’s commercial email practices.
The sextortion email scam last month that invoked a real password used by each recipient and threatened to release embarrassing Webcam videos almost certainly was not the work of one criminal or even one group of criminals. Rather, it’s likely that additional spammers and scammers piled on with their own versions of the phishing email after noticing that some recipients were actually paying up. The truth is we may never find out who’s responsible, but it’s still fun to follow some promising early leads and see where they take us.
Web site names ending in new top-level domains (TLDs) like .men, .work and .click are some of the riskiest and spammy-est on the Internet, according to experts who track such concentrations of badness online. Not that there still aren’t a whole mess of nasty .com, .net and .biz domains out there, but relative to their size (i.e. overall number of domains) these newer TLDs are far dicier to visit than most online destinations.
Take care when typing a domain name into a browser address bar, because it’s far too easy to fat-finger a key and wind up somewhere you don’t want to go. For example, if you try to visit some of the most popular destinations on the Web but omit the “o” in .com (and type .cm instead), there’s a good chance your browser will be bombarded with malware alerts and other misleading messages — potentially even causing your computer to lock up completely. As it happens, many of these domains appear tied to a marketing company whose CEO is a convicted felon and once self-proclaimed “Spam King.”
For several months I’ve been poking at a decent-sized spam botnet that appears to be used mainly for promoting adult dating sites. Having hit a wall in my research, I decided it might be good to publish what I’ve unearthed so far to see if this dovetails with any other research out there.
In late October 2016, an anonymous source shared with KrebsOnSecurity.com a list of nearly 100 URLs that — when loaded into a Firefox browser — each displayed what appeared to be a crude but otherwise effective “counter” designed to report in real time how many “bots” were reporting in for duty.
Here’s a set of archived screenshots of those counters illustrating how these various botnet controllers keep a running tab of how many “activebots” — hacked servers set up to relay spam — are sitting idly by and waiting for instructions.
Authorities in Spain have arrested a Russian computer programmer thought to be one of the world’s most notorious spam kingpins.
Spanish police arrested Pyotr Levashov under an international warrant executed in the city of Barcelona, according to Reuters. Russian state-run television station RT (formerly Russia Today) reported that Levashov was arrested while vacationing in Spain with his family.
According to numerous stories here at KrebsOnSecurity, Levashov was better known as “Severa,” the hacker moniker used by a pivotal figure in many popular Russian-language cybercrime forums. Severa was the moderator for the spam subsection of multiple online communities, and in this role served as the virtual linchpin connecting virus writers with huge spam networks that Severa allegedly created and sold himself.
Michael A. Persaud, a California man profiled in a Nov. 2014 KrebsOnSecurity story about a junk email purveyor tagged as one of the World’s Top 10 Worst Spammers, was indicted this week on federal wire fraud charges tied to an alleged spamming operation.
