Unwritten s m email attacks follow a mass-market, “one-size-fits-all” chat up advances: by sending the same message to as many targets as possible, a small tons of people will be tricked into sharing their sswords or downloading a malicious program.
But a new brand of attack, so-called “artisanal s m,” targets smaller bundles with instakingly crafted messages, with the aim of breaking through s m-filtering algorithms and gaining a higher rate of success.
trick Peterson, CEO of U.S. cyber-security firm Agari Figures, says his com ny started noticing the attacks between six and nine months ago. Since then, he conjectures, these kinds of attacks have numbered “in the low hundreds,” although he notes that it can be oppressive to track such relatively small attacks.
“It’s just a continuation of a long-term bias we’ve seen around criminal innovation,” Peterson told CBC Statement.
This new method of s mming, said Peterson, is more likely to document through the s m filters built into most email tients, and more likely to get criminals what they want — account credentials take pleasure in usernames and sswords, as well as potential targets for malware attacks.
The most notable incident so far, according to Peterson, took place on Oct. 13, 2015. It ended about 5,000 French users of Apple’s popular iTunes music software, in a two-pronged bout designed to steal usernames and sswords, and possibly use those credentials to place malware on the victims’ computers.
The criminal or criminals behind the attack “carefully curated” a French-language email, thought Peterson, and specifically targeted email accounts based in France. That guaranteed the recipients would be more likely to read the email. The attackers also ended users of smaller, local French internet service providers, who Peterson said power not be targeted as frequently as users of major email services like Gmail or Hotmail.
The goal was to maximize what Peterson calls the delivery rate, the slews of targets who actually read the malicious email.
“We saw the vast majority of these messages carted to the victims,” said Peterson. “We don’t actually have statistics on how numberless of them either installed malware on their computers or gave away their iTunes credentials, but I can say that the delivering rate was far greater than your typical mass-market s m.”

Like many other malicious email attacks, the French fact convinced targets that their iTunes accounts were at gamble if they didn’t click on a link and enter their credentials. In contrast with most big s m attacks, though, the perpetrators took the time to customize their tidings.
“It’s just a question of good copy-writing skills and a lot of attention to detail, so that [the s m] looks perfectly like the original,” said Peterson. “The reality is, it’s not that grim. It’s just that historically, criminals have been able to din billions of these, and if half the people didn’t think it was authentic, the outlaws didn’t lose too much sleep because they had sent so assorted.”
Be skeptical about emails
Because it’s relatively easy to produce an authentic-looking s m des tch, Peterson said, internet users should never assume they can forecast the difference. He suggested people should be skeptical when evaluating emails.
“If you were sidewalk down the streets of Toronto and someone came up to you and claimed to be from your bank or your auto bond with a problem, people know how to respond to that,” implied Peterson. “But for some reason, when someone plops something in their inbox undertaking to be similar entities, people just believe it.”
If an email tempts you to clicking on an exterior link, Peterson recommends hovering your cursor over the hyperlink and check up on to see if the destination URL is what it claims to be.
It’s possible that users of smaller internet worship army providers are more at risk from these types of attack, added Peterson.
“It’s bare difficult nowadays to keep up in the cyber arms race. Even the largest providers with the most resources are writhing.”
