Tourists Give Themselves Away by Looking Up. So Do Most Network Intruders.

By BrianKrebs

In large metropolitan areas, tourists are often easy to spot because they’re far more inclined than locals to gaze upward at the surrounding skyscrapers. Security experts say this same tourist dynamic is a dead giveaway in virtually all computer intrusions that lead to devastating attacks like data theft and ransomware, and that more organizations should set simple virtual tripwires that sound the alarm when authorized users and devices are spotted exhibiting this behavior.

In a blog post published last month, Cisco Talos said it was seeing a worrisome “increase in the rate of high-sophistication attacks on network infrastructure.” Cisco’s warning comes amid a flurry of successful data ransom and state-sponsored cyber espionage attacks targeting some of the most well-defended networks on the planet.

But despite their increasing complexity, a great many initial intrusions that lead to data theft could be nipped in the bud if more organizations started looking for the telltale signs of newly-arrived cybercriminals behaving like network tourists, Cisco says.

“One of the most important things to talk about here is that in each of the cases we’ve seen, the threat actors are taking the type of ‘first steps’ that someone who wants to understand (and control) your environment would take,” Cisco’s Hazel Burton wrote. “Examples we have observed include threat actors performing a ‘show config,’ ‘show interface,’ ‘show route,’ ‘show arp table’ and a ‘show CDP neighbor.’ All these actions give the attackers a picture of a router’s perspective of the network, and an understanding of what foothold they have.”

Cisco’s alert concerned espionage attacks from China and Russia that abused vulnerabilities in aging, end-of-life network routers. But at a very important level, it doesn’t matter how or why the attackers got that initial foothold on your network.

It might be zero-day vulnerabilities in your network firewall or file-transfer appliance. Your more immediate and primary concern has to be: How quickly can you detect and detach that initial foothold?

The same tourist behavior that Cisco described attackers exhibiting vis-a-vis older routers is also incredibly common early on in ransomware and data ransom attacks — which often unfurl in secret over days or weeks as attackers methodically identify and compromise a victim’s key network assets.

These virtual hostage situations usually begin with the intruders purchasing access to the target’s network from dark web brokers who resell access to stolen credentials and compromised computers. As a result, when those stolen resources first get used by would-be data thieves, almost invariably the attackers will run a series of basic commands asking the local system to confirm exactly who and where they are on the victim’s network.

This fundamental reality about modern cyberattacks — that cybercriminals almost always orient themselves by “looking up” who and where they are upon entering a foreign network for the first time — forms the business model of an innovative security company called Thinkst, which gives away easy-to-use tripwires or “canaries” that can fire off an alert whenever all sorts of suspicious activity is witnessed.

“Many people have pointed out that there are a handful of commands that are overwhelmingly run by attackers on compromised hosts (and seldom ever by regular users/usage),” the Thinkst website explains. “Reliably alerting when a user on your code-sign server runs whoami.exe can mean the difference between catching a compromise in week-1 (before the attackers dig in) and learning about the attack on CNN.”

These canaries — or “canary tokens” — are meant to be embedded inside regular files, acting much like a web beacon or web bug that tracks when someone opens an email.

The Canary Tokens website from Thinkst Canary lists nearly two-dozen free customizable canaries.

“Imagine doing that, but for file reads, database queries, process executions or patterns in log files,” the Canary Tokens documentation explains. “Canarytokens does all this and more, letting you implant traps in your production systems rather than setting up separate honeypots.”

Thinkst operates alongside a burgeoning industry offering so-called “deception” or “honeypot” services — those designed to confuse, disrupt and entangle network intruders. But in an interview with KrebsOnSecurity, Thinkst founder and CEO Haroon Meer said most deception techniques involve some degree of hubris.

“Meaning, you’ll have deception teams in your network playing spy versus spy with people trying to break in, and it becomes this whole counterintelligence thing,” Meer said. “Nobody really has time for that. Instead, we are saying literally the opposite: That you’ve probably got all these [security improvement] projects that are going to take forever. But while you’re doing all that, just drop these 10 canaries, because everything else is going to take a long time to do.”

The idea here is to lay traps in sensitive areas of your network or web applications where few authorized users should ever trod. Importantly, the canary tokens themselves are useless to an attacker. For example, that AWS canary token sure looks like the digital keys to your cloud, but the token itself offers no access. It’s just a lure for the bad guys, and you get an alert when and if it is ever touched.

One nice thing about canary tokens is that Thinkst gives them away for free. Head over to canarytokens.org, and choose from a drop-down menu of available tokens, including:

-a web bug / URL token, designed to alert when a particular URL is visited;
-a DNS token, which alerts when a hostname is requested;
-an AWS token, which alerts when a specific Amazon Web Services key is used;
-a “custom exe” token, to alert when a specific Windows executable file or DLL is run;
-a “sensitive command” token, to alert when a suspicious Windows command is run.
-a Microsoft Excel/Word token, which alerts when a specific Excel or Word file is accessed.

Much like a “wet paint” sign often encourages people to touch a freshly painted surface anyway, attackers often can’t help themselves when they enter a foreign network and stumble upon what appear to be key digital assets, Meer says.

“If an attacker lands on your server and finds a key to your cloud environment, it’s really hard for them not to try it once,” Meer said. “Also, when these sorts of actors do land in a network, they have to orient themselves, and while doing that they are going to trip canaries.”

Meer says canary tokens are as likely to trip up attackers as they are “red teams,” security experts hired or employed by companies seeking to continuously probe their own computer systems and networks for security weaknesses.

“The concept and use of canary tokens has made me very hesitant to use credentials gained during an engagement, versus finding alternative means to an end goal,” wrote Shubham Shah, a penetration tester and co-founder of the security firm Assetnote. “If the aim is to increase the time taken for attackers, canary tokens work well.”

Thinkst makes money by selling Canary Tools, which are honeypots that emulate full blown systems like Windows servers or IBM mainframes. They deploy in minutes and include a personalized, private Canarytoken server.

“If you’ve got a sophisticated defense team, you can start putting these things in really interesting places,” Meer said. “Everyone says their stuff is simple, but we obsess over it. It’s really got to be so simple that people can’t mess it up. And if it works, it’s the best bang for your security buck you’re going to get.”

A Serial Tech Investment Scammer Takes Up Coding?

By BrianKrebs

John Clifton Davies, a 60-year-old con man from the United Kingdom who fled the country in 2015 before being sentenced to 12 years in prison for fraud, has enjoyed a successful life abroad swindling technology startups by pretending to be a billionaire investor. Davies’ newest invention appears to be “CodesToYou,” which purports to be a “full cycle software development company” based in the U.K.

The scam artist John Bernard a.k.a. Alan John Mykailov (left) in a recent Zoom call, and a mugshot of John Clifton Davies from nearly a decade earlier.

Several articles here have delved into the history of John Bernard, the pseudonym used by a fake billionaire technology investor who tricked dozens of startups into giving him tens of millions of dollars.

John Bernard’s real name is John Clifton Davies, a convicted fraudster from the United Kingdom who is currently a fugitive from justice. For several years until reinventing himself again quite recently, Bernard pretended to be a billionaire Swiss investor who made his fortunes in the dot-com boom 20 years ago.

The Private Office of John Bernard” let it be known to investment brokers that he had tens of millions of dollars to invest in tech startups, and he attracted a stream of new victims by offering extraordinarily generous finder’s fees to brokers who helped him secure new clients. But those brokers would eventually get stiffed because Bernard’s company would never consummate a deal.

John Bernard’s former website, where he pretended to be a billionaire tech investor.

Bernard would promise to invest millions in tech startups, and then insist that companies pay tens of thousands of dollars worth of due diligence fees up front. However, the due diligence company he insisted on using — another Swiss firm called The Inside Knowledge GmbH — also was secretly owned by Bernard, who would invariably pull out of the deal after receiving the due diligence money.

A variety of clues suggest Davies has recently adopted at least one other identity — Alan John Mykhailov — who is listed as chairman of a British concern called CodesToYou LTD, incorporated in May 2022. The CodesToYou website says the company employs talented coders in several countries, and that its programmers offer “your ultimate balance between speed, cost and quality.”

The team from CodesToYou.

In response to questions from KrebsOnSecurity, CodesToYou’s marketing manager — who gave their name only as “Zhena” — said the company was not affiliated with any John Bernard or John Clifton Davies, and maintained that CodesToYou is a legitimate enterprise.

But publicly available information about this company and its leadership suggests otherwise. Official incorporation documents from the U.K.’s Companies House represent that CodesToYou is headed by an Alan John Mykhailov, a British citizen born in March 1958.

Companies House says Mykhailov is an officer in three other companies, including one called Blackstone Corporate Alliance Ltd. According to the Swiss business tracking service business-monitor.ch, Blackstone Corporate Alliance Ltd. is currently the entity holding a decision-making role in John Bernard’s fake due diligence company — The Inside Knowledge GmbH — which is now in liquidation.

Also listed as a partner in Blackstone Corporate Alliance Limited is Igor Hubskyi (a.k.a. Igor Gubskyi), a Ukrainian man who was previously president of The Inside Knowledge GmbH.

The CodesToYou website says the company’s marketing team lead is Maria Yakovleva, and the photo of this employee matches the profile for the LinkedIn account name “Maria Y.” That same LinkedIn profile and photo previously listed Maria by a different first and last name — Mariya Kulikova; back then, Ms. Kulikova’s LinkedIn profile said she was an executive assistant in The Private Office of Mr. John Bernard.

Companies House lists Alan John Mykhailov as a current officer in two other companies, including Frisor Limited, and Ardelis Solutions Limited. A cached copy of the now-defunct Ardelis Solutions website says it was a private equity firm.

CodesToYou’s Maria also included Ardelis Solutions in the work history section of her LinkedIn resume. That is, until being contacted by this author on LinkedIn, after which Maria’s profile picture and any mention of Ardelis Solutions were deleted.

Listed as head of business development at CodesToYou is David Bruno, a Canadian man whose LinkedIn profile says he is founder of an organization called “World Privacy Resource.” As KrebsOnSecurity reported in 2020, Bruno was at the time promoting himself as the co-CEO of a company called SafeSwiss Secure Communication AG, and the founder of another tech startup called Secure Swiss Data.

Secure Swiss Data’s domain — secureswissdata.com — is a Swiss concern that sells encrypted email and data services. According to DomainTools.com, that website name was registered in 2015 by The Inside Knowledge GmbH. In February 2020, a press release announced that Secure Swiss Data was purchased in an “undisclosed multimillion buyout” by SafeSwiss Secure Communication AG.

When reached in 2020 and asked about his relationship to Mr. Bernard, Mr. Bruno said the two were business partners and that he couldn’t imagine that Mr. Bernard would be involved in anything improper. To this day Mr. Bruno is the only person I’ve spoken to who has had anything positive to say about Mr. Bernard.

Mr. Bruno did not respond to requests for comment this time around, but his LinkedIn profile no longer makes any mention of Secure Swiss Data or SafeSwiss — both companies he claimed to run for many years. Nor does it mention CodesToYou. However, Mr. Bruno’s former company SafeSwiss is listed as one of the six “portfolio” companies whose services are promoted on the CodesToYou website.

In mid-2021, Bruno announced he was running for public office in Ontario.

“The Kenora resident is no stranger to the government as he contributed to Canada’s new Digital Charter, Bill C-11, which is a new Cyber Security policy,” reported Drydennow.com, a news website that covers Northwestern Ontario. Drydennow says the next federal election is expected to be held on or before Oct. 16, 2023.

John Clifton Davies was convicted in 2015 of swindling businesses throughout the U.K. that were struggling financially and seeking to restructure their debt. For roughly six years, Davies ran a series of firms that pretended to offer insolvency services, but instead simply siphoned what little remaining money these companies had.

The very first entity mentioned in the technology portfolio advertised on the CodesToYou website is called “MySolve,” and it purports to offer a “multi-feature platform for insolvency practitioners.”

Mr. Davies’ fourth wife, Iryna Davies, is listed as a director of one of the insolvency consulting businesses in the U.K. that was part of John Davies’ 2015 fraud conviction. Prior to his trial for fraud, Davies served 16 months in jail before being cleared of murdering his third wife on their honeymoon in India: Colette Davies, 39, died after falling 80 feet from a viewing point at a steep gorge in the Himachal Pradesh region of India.

Mr. Davies was charged with murder and fraud after he attempted to collect GBP 132,000 in her life insurance payout, but British prosecutors ultimately conceded they did not have enough evidence to convict him.

The scams favored by Davies and his alter egos are smart because he never approaches investors directly; rather, investors are incentivized to put his portfolio in front of tech firms seeking financial backing. And all the best cons begin as an idea or possibility planted in the target’s mind.

It’s also a reliable scam because companies bilked by small-time investment schemes rarely pursue legal action, mainly because the legal fees involved can quickly surpass the losses. On top of that, many victims will likely be too ashamed to admit their duping. Victims who do press their case in court and win then face the daunting challenge of collecting damages from a slew of ephemeral shell corporations.

The latest Bernard victim to speak publicly — a Norwegian company hoping to build a fleet of environmentally friendly shipping vessels — is now embroiled in a lawsuit over a deal gone bad. As part of that scam, Bernard falsely claimed to have secured $100 million from six other wealthy investors, including the founder of Uber and the artist Abel Makkonen Tesfaye, better known as The Weeknd.
