Feds Charge Two In Lizard Squad Investigation

October 6, 2016

The U.S. Justice Department has charged two 19-year-old men alleged to be core members of the hacking groups Lizard Squad and PoodleCorp. The pair are charged with credit card theft and operating so-called “booter”or “stresser” services that allowed paying customers to launch powerful attacks designed to knock Web sites offline.

Who Makes the IoT Things Under Attack?

October 3, 2016

As KrebsOnSecurity observed over the weekend, the source code that powers the “Internet of Things” (IoT) botnet responsible for launching the historically large distributed denial-of-service (DDoS) attack against KrebsOnSecurity last month has been publicly released. Here’s a look at which devices are being targeted by this malware.

Source Code for IoT Botnet ‘Mirai’ Released

October 1, 2016

The source code that powers the “Internet of Things” (IoT) botnet responsible for launching the historically large distributed denial-of-service (DDoS) attack against KrebsOnSecurity last month has been publicly released, virtually guaranteeing that the Internet will soon be flooded with attacks from many new botnets powered by insecure routers, IP cameras, DVRs and other easily hackable IoT devices.

‘Money Mule’ Gangs Turn to Bitcoin ATMs

September 29, 2016

Fraudsters who hack corporate bank accounts typically launder stolen funds by making deposits from the hacked company into accounts owned by “money mules,” willing or unwitting dupes recruited through work-at-home job scams. The mules usually are then asked to withdraw the funds in cash and wire the money to the scammers. Increasingly, however, the mules are being instructed to remit the stolen money via Bitcoin ATMs.

Inside Arizona’s Pump Skimmer Scourge

September 27, 2016

Crooks who deploy skimming devices made to steal payment card details from fuel station pumps don’t just target filling stations at random: They tend to focus on those that neglect to deploy various tools designed to minimize such scams, including security cameras, non-standard pump locks and tamper-proof security tape. But don’t take my word for it: Here’s a look at fuel station compromises in 2016 as documented by the state of Arizona, which has seen a dramatic spike in fuel skimming attacks over the past year.

The Democratization of Censorship

September 25, 2016

John Gilmore, an American entrepreneur and civil libertarian, once famously quipped that “the Internet interprets censorship as damage and routes around it”. This notion undoubtedly rings true for those who see national governments as the principal threats to free speech.

However, events of the past week have convinced me that one of the fastest-growing censorship threats on the Internet today comes not from nation-states, but from super-empowered individuals who have been quietly building extremely powerful cyber weapons with transnational reach.

KrebsOnSecurity Hit With Record DDoS

September 21, 2016

On Tuesday evening, KrebsOnSecurity.com was the target of an extremely large and unusual distributed denial-of-service (DDoS) attack designed to knock the site offline. The attack did not succeed thanks to the hard work of the engineers at Akamai, the company that protects my site from such digital sieges. But according to Akamai, it was nearly double the size of the largest attack they’ve seen previously, and was among the biggest assaults the Internet has ever witnessed.

DDoS Mitigation Firm Has History of Hijacks

September 20, 2016

Last week, KrebsOnSecurity detailed how BackConnect Inc. — a company that defends victims against large-scale distributed denial-of-service (DDoS) attacks — admitted to hijacking hundreds of Internet addresses from a European Internet service provider in order to glean information about attackers who were targeting BackConnect. According to an exhaustive analysis of historic Internet records, the BackConnect appears to have a history of such “hacking back” activity.

Ransomware Getting More Targeted, Expensive

September 15, 2016

I shared a meal not long ago with a source who works at a financial services company. The subject of ransomware came up and he told me that a server in his company had recently been infected with a particularly nasty strain that spread to several systems before the outbreak was quarantined. He said the folks in finance didn’t bat an eyelash when asked to authorize several payments of $600 to satisfy the Bitcoin ransom demanded by the intruders: After all, my source confessed, the data on one of the infected systems was worth millions — possibly tens of millions — of dollars, but for whatever reason the company didn’t have backups of it.

This anecdote has haunted me because it speaks volumes about what we can likely expect in the very near future from ransomware — malicious software that scrambles all files on an infected computer with strong encryption, and then requires payment from the victim to recover them.

Adobe, Microsoft Push Critical Updates

September 14, 2016

Adobe and Microsoft on Tuesday each issued updates to fix multiple critical security vulnerabilities in their software. Adobe pushed a patch that addresses 29 security holes in its Flash Player software. Microsoft released some 14 patch bundles to correct at least 50 flaws in Windows and associated software, including a zero-day bug in Internet Explorer.
