Alleged ‘Satori’ IoT Botnet Operator Sought Media Spotlight, Got Indicted

A 20-year-old from Vancouver, Washington was indicted last week on federal hacking charges and for allegedly operating the “Satori” botnet, a malware strain unleashed last year that infected hundreds of thousands of wireless routers and other “Internet of Things” (IoT) devices. This outcome is hardly surprising given that the accused’s alleged alter ego has been relentless in seeking media attention for this global crime machine.

The Daily Beast‘s Kevin Poulsen broke the news last week that federal authorities in Alaska indicted Kenneth Currin Schuchman of Washington on two counts of violating the Computer Fraud and Abuse Act by using malware to damage computers between August and November 2017.

The 3-page indictment (PDF) is incredibly sparse, and includes few details about the meat of the charges against Schuchman. But according to Poulsen, the charges are related to Schuchman’s alleged authorship and use of the Satori botnet. Satori, also known as “Masuta,” is a variant of the Mirai botnet, a powerful IoT malware strain that first came online in July 2016.

“Despite the havoc he supposedly wreaked, the accused hacker doesn’t seem to have been terribly knowledgeable about hacking,” Poulsen notes.

Schuchman reportedly went by the handle “Nexus Zeta,” the nickname used by a fairly inexperienced and clumsy ne’er-do-well who has tried on multiple occasions to get KrebsOnSecurity to write about the Satori botnet. In January 2018, Nexus Zeta changed the login page for his botnet control panel that he used to remotely control his hacked routers to include a friendly backhanded reference to this author:

The login prompt for Nexus Zeta’s IoT botnet included the message “Masuta is powered and hosted on Brian Kreb’s [sic] 4head.” To be precise, it’s a 5head.

This wasn’t the first time Nexus Zeta said hello. In late November 2017, he chatted me up on on Twitter and Jabber instant message for several days. Most of the communications came from two accounts: “9gigs_ProxyPipe” on Twitter, and ogmemes123@jabber.ru (9gigs_ProxyPipe would later change its Twitter alias to Nexus Zeta, and Nexus Zeta himself admitted that 9gigs_ProxyPipe was his Twitter account.)

In each case, this person wanted to talk about a new IoT botnet that he was “researching” and that he thought deserved special attention for its size and potential disruptive impact should it be used in a massive Distributed Denial-of-Service (DDoS) attack aimed at knocking a Web site offline — something for which Satori would soon become known.

A Jabber instant message conversation with Nexus Zeta on Nov. 29, 2017.

Nexus Zeta’s Twitter nickname initially confused me because both 9gigs and ProxyPipe are names claimed by Robert Coelho, owner of ProxyPipe hosting (9gigs is a bit from one of Coelho’s Skype account names). Coelho’s sleuthing was quite instrumental in helping to unmask 21-year-old New Jersey resident Paras Jha as the author of the original Mirai IoT botnet (Jha later pleaded guilty to co-authoring and using Mirai and is due to be sentenced this month in Alaska and New Jersey). “Ogmemes” is from a nickname used by Jha and his Mirai botnet co-author.

On Nov. 28, 2017, 9gigs_ProxyPipe sent a message to the KrebsOnSecurity Twitter account:

“I have some information in regards to an incredibly dangerous IoT botnet you may find interesting,” the Twitter message read. “Let me know how you would prefer to communicate assuming you are interested.”

We connected on Jabber instant message. In our chats, Ogmemes123 said he couldn’t understand why nobody had noticed a botnet powered by a Mirai variant that had infected hundreds of thousands of IoT devices (he estimated the size of the botnet to be about 300,000-500,000 at the time). He also talked a lot about how close he was with Jha. Nexus Zeta’s Twitter account profile photo is a picture of Paras Jha. He also said he knew this new botnet was being used to attack ProxyPipe.

Less than 24 hours after that tweet from Nexus Zeta, I heard from ProxyPipe’s Coelho. They were under attack from a new Mirai variant. Continue reading →

Twitter Bots Use Likes, RTs for Intimidation

I awoke this morning to find my account on Twitter (@briankrebs) had attracted almost 12,000 new followers overnight. Then I noticed I’d gained almost as many followers as the number of re-tweets (RTs) earned for a tweet I published on Tuesday. The tweet stated how every time I tweet something related to Russian President Vladimir Putin I get a predictable stream of replies that are in support of President Trump — even in cases when neither Trump nor the 2016 U.S. presidential campaign were mentioned.

This tweet about Putin generated more than 12,000 retweets and likes in a few hours.

This tweet about Putin generated more than 12,000 retweets and likes in a few hours.

Upon further examination, it appears that almost all of my new followers were compliments of a social media botnet that is being used to amplify fake news and to intimidate journalists, activists and researchers. The botnet or botnets appear to be targeting people who are exposing the extent to which sock puppet and bot accounts on social media platforms can be used to influence public opinion.

After tweeting about my new bounty of suspicious-looking Twitter friends I learned from my legitimate followers on Twitter that @briankrebs wasn’t alone and that several journalists and nonprofit groups that have written recently about bot-like activity on Twitter experienced something similar over the past few days.

These tweet and follow storms seem capable of tripping some kind of mechanism at Twitter that seeks to detect when accounts are suspected of artificially beefing up their follower counts by purchasing followers (for more on that dodgy industry, check out this post).

Earlier today, Daily Beast cybersecurity reporter Joseph Cox had his Twitter account suspended temporarily after the account was the beneficiary of hundreds of bot followers over a brief period on Tuesday. This likely was the goal in the campaign against my site as well.

Cox observed the same likely bot accounts that followed him following me and a short list of other users in the same order.

“Right after my Daily Beast story about suspicious activity by pro-Kremlin bots went live, my own account came under attack,” Cox wrote.

Let that sink in for a moment: A huge collection of botted accounts — the vast majority of which should be easily detectable as such — may be able to abuse Twitter’s anti-abuse tools to temporarily shutter the accounts of real people suspected of being bots!

Overnight between Aug. 28 and 29, a large Twitter botnet took aim at the account for the Digital Forensic Research Lab, a project run by the Atlantic Council, a political think-tank based in Washington, D.C. In a post about the incident, DFRLab said the attack used fake accounts to impersonate and attack its members.

Those personal attacks — which included tweets and images lamenting the supposed death of DFR senior fellow Ben Nimmo — were then amplified and re-tweeted by tens of thousands of apparently automated accounts, according to a blost post published today by DFRLab.

Suspecting that DFRLab was now being followed by many more botted accounts that might retweet or otherwise react to any further tweets mentioning bot attacks, Nimmo cleverly composed another tweet about the bot attack — only this time CC’ing the @Twitter and @Twittersupport accounts. Sure enough, that sly tweet was retweeted by bots more than 73,000 times before the tweet storm died down.

“We considered that the bots had probably been programmed to react to a relatively simple set of triggers, most likely the words ‘bot attack’ and the @DFRLab handle,” Nimmo wrote. “To test the hypothesis, we posted a tweet mentioning the same words, and were retweeted over 500 times in nine minutes — something which, admittedly, does not occur regularly with our human followers.” Read more about the DFRLab episode here.

This week’s Twitter bot drama follows similar attacks on public interest groups earlier this month. On Aug. 19, the award-winning investigative journalism site ProPublica.org published the story, Leading Tech Companies Help Extremist Sites Monetize Hate.

On the morning of Tuesday, Aug. 22, several ProPublica reporters began receiving email bombs — email list subscription attacks that can inundate a targeted inbox with dozens or even hundreds of email list subscription confirmation requests per minute. These attacks are designed to deluge the victim’s inbox with so many subscription confirmation requests that it becomes extremely time-consuming to fish out the legitimate messages amid the dross.

On Wednesday ProPublica author Jeff Larson saw a tweet he sent about the email attacks get re-tweeted 1,200 times. Later that evening, senior reporting fellow Lauren Kirchner noticed a similar sized response to her tweet about how the subscription attack was affecting her ability to respond to messages.

On top of that, several ProPublica staffers suddenly gained about 500 new followers. On Thursday, ProPublica’s managing editor Eric Umansky noticed that a tweet accusing ProPublica of being an “alt-left #HateGroup and #FakeNews site funded by Soros” had received more than 23,000 re-tweets.

DNI: Putin Led Cyber, Propaganda Effort to Elect Trump, Denigrate Clinton

Russian President Vladimir Putin directed a massive propaganda and cyber operation aimed at discrediting Hillary Clinton and getting Donald Trump elected, the top U.S. intelligence agencies said in a remarkable yet unshocking report released on Friday.

The 25-page dossier from the Office of the Director of National Intelligence stopped short of saying the Russians succeeded at influencing the outcome of the election, noting that the report did not attempt to make an assessment on that front. But it makes the case that “Russia’s intelligence services conducted cyber operations against targets associated with the 2016 US presidential election, including targets associated with both major US political parties.”

“We assess with high confidence that Russian military intelligence (General Staff Main Intelligence Directorate or GRU) used the Guccifer 2.0 persona and DCLeaks.com to release US victim data obtained in cyber operations publicly and in exclusives to media outlets and relayed material to WikiLeaks,” the DNI report reads.

The report is a quick and fascinating read. One example: It includes a fairly detailed appendix which concludes that the U.S.-based but Kremlin-financed media outlet RT (formerly Russia Today) is little more than a propaganda machine controlled by Russian intelligence agencies.

“Moscow’s influence campaign followed a Russian messaging strategy that blends covert intelligence operations—such as cyber activity—with overt efforts by Russian Government agencies, state-funded media, third-party intermediaries, and paid social media users or ‘trolls,'” reads the report.

The DNI report is remarkable for several reasons. First, it publicly accuses Russia’s President of trying to meddle with the U.S. election and to hack both political parties. Also, as The New York Times observed, it offers “a virtually unheard-of, real-time revelation by the American intelligence agencies that undermined the legitimacy of the president who is about to direct them.”

However, those who’ve been clamoring for more technical evidence to support a conclusion that Russian intelligence agencies were behind the phishing, malware attacks and email leaks at The Democratic National Committee (DNC) and Clinton campaign likely will be unmoved by this report. Those details will remain safely hidden from public view in the classified version of the report.

Last week, the FBI and Department of Homeland Security issued a joint report (PDF) on some of the malware and Internet resources used in the DNC intrusion. But many experts criticized it as a poorly-written, jumbled collection of threat indicators and digital clues that didn’t all quite lead where they should.

Others were perplexed by the high confidence level the agencies assigned to the findings in their unclassified report, noting that neither the FBI nor DHS examined the DNC hard drives that were compromised in the break-in (that work was done by private security firm Crowdstrike).

Former black-hat hacker turned Wired and Daily Beast contributing editor Kevin Poulsen slammed the FBI/DHS report as “so aimless that it muddies the clear public evidence that Russia hacked the Democratic Party to affect the election, and so wrong it enables the Trump-friendly conspiracy theorists trying to explain away that evidence.”

Granted, trying to reconstruct a digital crime scene absent some of the most important pieces of evidence is a bit like attempting to assemble a jigsaw puzzle with only half of the pieces. But as digital forensics and security expert Jonanthan Zdziarksi noted via Twitter last night, good old fashioned spying and human intelligence seems to have played a bigger role in pinning the DNC hack on the Russians.

“The DNI report subtly implied that more weight was put on our intelligence coming from espionage operations than on cyber warfare,” Zdziarski wrote. “As someone who’s publicly called out the FBI over misleading the public and the court system, I believe the DNI report to be reliable. I also believe @CrowdStrike’s findings to be reliable based on the people there and their experience with threat intelligence.”
