NEW YORK: The stunning revelation that a tabloid obtained below-the-belt selfies of Amazon founder Jeff Bezos - the world's richest man - suggests that even billionaires are not out of the reach of hackers.
Bezos came out fighting this week, accusing the National Enquirer of blackmailing him with lurid pictures of him and his mistress, and pre-empting the threat to publish by releasing details of the images himself.
But for Mark Johnson, CEO of Sovereign Intelligence, the incident makes clear that "no one is beyond the reach of cyber exploitation."
"It's a curious irony that billionaires demonstrate astounding acumen related to their own industries, and yet seemingly ignore the minutiae of common-place security measures."
Johnson sees billionaires and top executives as especially vulnerable because their personal information is a gold mine for criminals, intelligence agencies and competitors.
"Obtaining their personal data is like having keys to the kingdom," said Johnson, potentially providing priceless insight into the thinking and strategies of the world's most powerful business leaders.
Ian Bremmer, the founder of the Eurasia Group think tank, put it more bluntly.
"If the National Enquirer has @JeffBezos dick pics, don't tell me China doesn't have @Amazon IP and strategy," he tweeted.
INCREASE IN CALLS
Since the revelations about Bezos, whose fortune is estimated at more than US$130 billion, computer security experts interviewed by AFP report an increase in calls from wealthy clients asking them to verify that their computer systems and devices were not hacked.
"Today's threats however are not necessarily trying to breach the walls of the castle - they are already inside, residing on personal devices," said Kris Coleman, the founder of Red Five Security.
"Experience has shown that the typical breach is not discovered for eight months."
In this ever-more connected age, more and more personal data is stored online - from social security numbers to bank details, driver's license numbers and personal addresses.
As a result the focus of security measures for the ultra-wealthy has shifted from bodyguards and sophisticated alarms towards risk management to protect their assets, their image and their "legacy."
The super-wealthy will typically have their own computer security service and also call on external companies for regular evaluation of their devices because a large number of hacks are detected by third parties, according to observers.
Mark Zuckerberg, Facebook's CEO, spent US$7.3 million on his security in 2017, up from $4.2 million in 2015 - astronomical sums that the social network deemed justified due to his prominence.
Last July, Facebook said it would give him US$10 million more per year to strengthen his security.
"Protection from colluding insiders working from positions of trust; or, against an intelligence agency trying to attack from the outside is going to require a large investment, a lot of experience, and vigilance," said Coleman.
For Johnson, "no one's data is that well protected. Think of all the third-party platforms that have your social security number, or banking information, or that hold your personal pictures."
Just days before Bezos disclosed that a tabloid had obtained his intimate selfies, a fellow billionaire - Joe Ricketts, the founder of the broker TD Ameritrade Holding Corporation - was ensnared in scandal following the release of private messages.
The American news site Splinter published a series of racist emails from Ricketts, without saying how it obtained them.
The exchanges, some of which date back to 2009, show the 77-year-old sharing and apparently endorsing racist jokes and conspiracy theories. He has since apologized.
Back in August 2015, a cyber attack on the Ashley-Madison extramarital dating site revealed that American billionaire Dan Loeb had an account there.
Bezos did not say how the National Enquirer obtained his pictures, but experts say the most common method is for a hacker to usurp the identity of a member of a person's entourage.
"The adversary would send a message to the target asking them to click on a link in a text or email," Coleman explained.
"The sender's real identity is hidden but the target trusts the message from their 'friend' and clicks the link unlocking malware or another type of attack on that device."
