Il mio nuovo libro su Angular non è ancora uscito, ma è già uno scam

Mancano soltanto pochi giorni all'uscita del mio nuovo libro e, come sempre, l'attesa è tanta. Ancora una volta abbiamo dovuto attendere il rilascio dell'ultima versione "final" di Angular, proprio come già accaduto in passato: la volta scorsa si trattava della versione 5.0.0, inizialmente prevista per il 18 settembre , quindi rimandata di oltre un mese (23 ottobre) e infine rilasciata il 2 novembre dopo ben nove release candidate. Dopo quell'esperienza pensavamo di averle viste tutte, e invece stavolta ci siamo superati, dovendo affrontare un ritardo di oltre due mesi (da dicembre a febbraio) costellato da quattordici release candidate, un vero e proprio record! Ad ogni buon conto, finalmente l'attesa è finita: nella notte tra il 6 e il 7 febbraio 2020, ovvero poco più di 24 ore fa, la versione 9.0.0 di Angular è stata rilasciata su GitHub, consentendo al libro di entrare in stampa e all'editore Packt Publishing di rispettare la data di pubblicazione, fissata pessimisticamente (neanche tanto, come poi s'è visto!) all'11 febbraio.

Tutto è bene quel che finisce bene, direte voi... e invece no! Effettuando alcune ricerche su Google per calcolare il livello di indicizzazione SEO raggiunto dal sito mi sono imbattuto in uno strano post twitter che menzionava il mio libro - con tanto di ISIN, nome, autore e descrizione - invitando a scaricare l'e-book mediante un link non meglio identificato.

Il profilo, intestato a una certa Christine H. McAndrews, sembrava ovviamente tutto meno che autentico, presentando anzi tutte le più evidenti caratteristiche del classico account fake: zero following/follower, iscrizione a gennaio 2020, e una sfilza di post recanti informazioni su come scaricare libri di prossima uscita, tutti corredati da link che puntano allo stesso host.

Il sito indicato dai link di "Christine" ha l'aspetto di un forum a carattere generale, ma è sufficiente una prima occhiata per comprendere che si tratta di una scam page che tenta di spacciarsi come una discussione di appassionati che parlano del libro.

La pagina è stata programmata in modo tale da riempire "dinamicamente" una serie di placeholder disseminati all'interno dei vari fake-post con il nome del libro e dell'autore presenti nei parametri della URL: questo consente a "Christine", che ovviamente altri non è che un tweet-bot automatico, di utilizzarla nei suoi post per ciascuno dei libri che l'autore di questa truffa ha intenzione di "promuovere", o per meglio dire di utilizzare come esche per attirare qualche navigatore sprovveduto desideroso di scaricarli a costo zero. Tra i parametri c'è persino la URL di un'immagine del libro presa da Amazon, che purtroppo è stata implementata male visto che - ad oggi - nella pagina non compare. Inutile dire che, nel finto thread sviluppato dalla pagina, un (finto) utente risponde alla domanda dell'opening poster suggerendo un servizio di "download gratuito di e-book" (all'interno del quale si consumerà la truffa vera e propria):

La truffa prosegue mettendo in scena la classica trovata del dubbio fugato dalla smentita, un classico espediente per conquistare la fiducia della potenziale vittima e spingerla a compiere una call-to-action potenzialmente rischiosa: un utente (finto) risponde obiettando che quel sito chiede la carta di credito...

... ma è subito seguito da una serie di altri utenti (anch'essi finti, ovviamente) che confermano l'autenticità e l'affidabilità del servizio: "non temere, è sicurissimo: metti la carta e potrai procedere con il download!"

Il messaggio viene reiterato dalla conferma dell'utente (finto) originario, che conferma il funzionamento del sito: veniamo così a sapere che la carta di credito serve solo a confermare che chi vuole scaricare l'ebook è una persona reale, praticamente un CAPTCHA:

La scenetta si conclude con un'altro paio di utenti che confermano la genuinità del sito e lodano le caratteristiche del servizio: la truffa è servita.

Nel caso in cui vogliate dare un'occhiata alla pagina in questione, potete accedervi copiando l'URL che trovate qui di seguito e incollandolo nella barra degli indirizzi del vostro browser: https://toositego.ml/az.php?q=ASP.NET+Core+3+and+Angular+9+-+Third+Edition+-+Valerio+De+Sanctis&i=https://m.media-amazon.com/images/I/61kIIUNGgLL._AC_UY327_FMwebp_QL65_.jpg Inutile dire che si tratta di un'operazione da compiere con cautela e facendo molta attenzione: la pagina al momento non contiene script dannosi, ma nulla vieta agli scammer che gestiscono il dominio di modificarne i contenuti nel prossimo futuro; quel che è certo è che non dovete per nessun motivo accedere al link contenuto (e più volte reiterato) all'interno del thread, men che meno inserire la vostra carta di credito o qualsivoglia altro dato.

Conclusione

Per il momento è tutto: devo dire che questo scam mi ha davvero sorpreso, ero al corrente di simili stratagemmi ma vedersi "protagonista" di un raggiro così "futuribile" (in tutti i sensi) fa comunque un certo effetto. Prima di salutarvi, vi ricordo che - se volete dare un'occhiata al libro ASP.NET Core 3 and Angular 9 senza rischiare brutte sorprese - potete farlo gratuitamente sfruttando le anteprime disponibili sia su Amazon che sul sito dell'editore ai seguenti indirizzi: ASP.NET Core 3 and Angular 9 su Amazon.it ASP.NET Core 3 and Angular 9 su Amazon.com ASP.NET Core 3 and Angular 9 sul sito Packt Publishing Alla prossima!   Read the full article

My new Angular book is not out yet, but is already a scam

Writing a programming book is a task that almost always proves to be much more difficult than expected, especially when dealing with mutable and unpredictable frameworks such as ASP.NET Core and Angular. Once again we had to wait for the release of the latest "final" version of Angular, just as already happened in 2017 with my previous book: Angular 5.0.0 version, initially scheduled for September 18th, was postponed for over a month ( October 23th) and then released on November 2 after no less than nine release candidates. After that experience we all thought we couldn't experience anything worse, but we were wrong: the latest major release of Angular experienced a delay of over two months (from December to February) and was further delayed by fourteen release candidates, thus arguably being a world record of some sort. Luckily enough, the wait is finally over: on the night between 6th and 7th February 2020, just over 24 hours ago, Angular version 9.0.0 was released on GitHub, thus allowing me to finishi the book in due time and the publisher - Packt Publishing - to honor the expected release date, which had been set to February 11th.

Now that the expected schedule has been successfully met, I would like to spend a couple words - well, maybe a bit more than that - to tell you about a rather odd experience I had this afternoon while surfing the web. Truth to be told, there's a high chance that you've heard similar stories already: however, I personally think that such kind of fun facts never gets old enough; other than being hilarious, they can also greatly help to understand how the web that we're browsing nowadays actually works. So, while issuing some search queries on Google to calculate the SERP indexing level reached by the sites that had the book available for preorder, I came across this strange twitter post:

There was no mistake there: the post was clearly mentioning my book, with matching ISIN, name, author and description; and it was also telling me to download it for free (in e-book format) my clicking on an unidentified link. Such truly incredible opportunity could be seized since February 4th, judging by the tweet's time stamp: 7 days before the book's planned release date, and - most importantly - 2 days before I've actually finished writing it (!) The twitter profile was just like you might expect from a fake account: owned by Christine H. McAndrews, a cute girl with zero followers, registered in January 2020, and only tweeting about forthcoming books and how to download them. Needless to say, each and every link was pointing to the same website.

Given such intriguing scenario, I couldn't avoid taking a look to the website itself. Eventually, I landed on a blatant scam page who looked just like a bulletin board system, where some (fake) users were enthusiastically talking about my book:

The page worked in a rather fun way that deserves a couple words: it was programmed to "dynamically" fill a series of placeholders with the book info (name, author, and so on) brought by the URL GET parameters: those placeholders were scattered within the page, thus trying to emulate a plausible "thread" of enthusiasts who were talking about the book. Such neat mechanic allows "Christine", who's obviously an automatic tweet-bot, to spam the same URL in her posts, filling the GET parameters with the metadata taken from the upcoming books she wants to "promote"; a great bait for any unwary twitter (or google) user looking to download them to no cost. (side note: the GET parameters also included the image URL for the book cover hosted on Amazon; unfortunately,  the fake page doesn't seem to have properly implemented it, since it's not showing anywhere). The fake thread developed by the page portrays a rather predictable scene, typical of online scams. The opening message is written by a user which is desperately looking for the book because he/she can't find it anywhere; a (fake) user responds to the request, suggesting a link to a "free e-book download" service (the actual scam website):

The scam attempt continues by staging the typical gimmick of the doubt dispelled by the denial, a trivial social engineering trick to win the trust of the potential victim and push her to perform a potentially risky call-to-action: the (fake) opening poster replies objecting that that site asks for a credit card ...

... but is immediately reassured by another (fake) user who confirms the authenticity and reliability of the service: "don't worry, it's all trusted: just put the card in and proceed with the download!"

The trust level is further raised by the original (fake) user , who confirms that everything went really well; the credit card was just a way to check it was a real user, just like a CAPTCHA: now everything makes sense!

The scene ends with another couple of users who confirm the authenticity of the site and praise the characteristics of the service: the scam is served.

In the unlikely case you want to take a look at the "scam forum thread" page, you can access it by copying the following URLand pasting it in your browser's address bar: https://toositego.ml/az.php?q=ASP.NET+Core+3+and+Angular+9+-+Third+Edition+-+Valerio+De+Sanctis&i=https://m.media-amazon.com/images/I/61kIIUNGgLL._AC_UY327_FMwebp_QL65_.jpg Needless to say, you should only do that if you know what you're doing: although the page currently doesn't host malicious scripts, nothing prevents the administrators (aka the scammers) from change such behavior in the near future; however, the real threat is inside the suggested "download link" that appears within the thread: be sure to not visit it, let alone enter your credit card or any other data anywhere.

Conclusion

I must honestly say that this scam really surprised me: I was aware of similar tricks, but seeing my name (and book) inside that fake thread was rather awkward. If you want to take a look at the ASP.NET Core 3 and Angular 9 book without scam pages, remember that you can do it for free by taking advantage of the PDF previews available on Amazon and on the publisher's websites at the following URLs: ASP.NET Core 3 and Angular 9 su Amazon.it ASP.NET Core 3 and Angular 9 su Amazon.com ASP.NET Core 3 and Angular 9 sul sito Packt Publishing I hope you'll enjoy the book at least as much as this story!   Read the full article
