On October 10, 2022, there were 576,562 LinkedIn accounts that listed their current employer as Apple Inc. The next day, half of those profiles no longer existed. A similarly dramatic drop in the number of LinkedIn profiles claiming employment at Amazon comes as LinkedIn is struggling to combat a significant uptick in the creation of fake employee accounts that pair AI-generated profile photos with text lifted from legitimate users.
Someone has recently created a large number of fake LinkedIn profiles for Chief Information Security Officer (CISO) roles at some of the world’s largest corporations. It’s not clear who’s behind this network of fake CISOs or what their intentions may be. But the fabricated LinkedIn identities are confusing search engine results for CISO roles at major companies, and they are being indexed as gospel by various downstream data-scraping sources.
When KrebsOnSecurity last month explored how cybercriminals were using hacked email accounts at police departments worldwide to obtain warrantless Emergency Data Requests (EDRs) from social media and technology providers, many security experts called it a fundamentally unfixable problem. But don’t tell that to Matt Donahue, a former FBI agent who recently quit the agency to launch a startup that aims to help tech companies do a better job screening out phony law enforcement data requests — in part by assigning trustworthiness or “credit ratings” to law enforcement authorities worldwide.
If you received a link to LinkedIn.com via email, SMS or instant message, would you click it? Spammers, phishers and other ne’er-do-wells are hoping you will, because they’ve long taken advantage of a marketing feature on the business networking site which lets them create a LinkedIn.com link that bounces your browser to other websites, such as phishing pages that mimic top online brands (but chiefly Linkedin’s parent firm Microsoft).
One of the oldest scams around — the fake job interview that seeks only to harvest your personal and financial data — is on the rise, the FBI warns. Here’s the story of a recent LinkedIn impersonation scam that led to more than 100 people getting duped, and one almost-victim who decided the job offer was too-good-to-be-true.
A ridiculous number of companies are exposing some or all of their proprietary and customer data by putting it in the cloud without any kind of authentication needed to read, alter or destroy it. When cybercriminals are the first to discover these missteps, usually the outcome is a demand for money in return for the stolen data. But when these screw-ups are unearthed by security professionals seeking to make a name for themselves, the resulting publicity often can leave the breached organization wishing they’d instead been quietly extorted by anonymous crooks.
One of the risks of using social media networks is having information you intend to share with only a handful of friends be made available to everyone. Sometimes that over-sharing happens because friends betray your trust, but more worrisome are the cases in which a social media platform itself exposes your data in the name of marketing.
At least once a month, sometimes more, readers write in to ask how they can break into the field of computer security. Some of the emails are from people in jobs that have nothing to do with security, but who are fascinated enough by the field to contemplate a career change. Others are already in an information technology position but are itching to segue into security. I always respond with my own set of stock answers, but each time I do this, I can’t help but feel my advice is incomplete, or at least not terribly well-rounded.
I decided to ask some of the brightest minds in the security industry today what advice they’d give. Almost everyone I asked said they, too, frequently get asked the very same question, but each had surprisingly different takes on the subject. Today is the first installment in a series of responses to this question. When the last of the advice columns have run, I’ll create an archive of them all so that the next time someone asks how they can break into security, I’ll have more to offer than just my admittedly narrow perspectives on the matter.
Nearly every time I write about a small to mid-sized business that has lost hundreds of thousands of dollars after falling victim to a malicious software attack, readers ask how the perpetrators broke through the victim organization’s defenses, and which type of malware paved the way. Normally, victim companies don’t know or disclose that information, so to get a better idea, I’ve put together a rough profile of the top daily email-based malware attacks over the past month.
Separate password breaches last week at LinkedIn, eHarmony and Last.fm exposed millions of credentials, and once again raised the question of whether any company can get password security right. To understand more about why companies keep making the same mistakes and what they might do differently to prevent future password debacles, I interviewed Thomas Ptacek, a security researcher with Matasano Security.
Ptacek is just one of several extremely smart researchers I’ve been speaking with about this topic. Below are some snippets from a conversation we had last week.
