Let Adware Be Treated As Malware Or Virus

Let adware be treated as malware, Canuck boffins declare once breaking open Wajam ad gizmo. Analysis The technology trade has various terms for a sneaky software package. As well as malware, adware, spyware, ransomware, and also the ever lovable PUPs – doubtless unwanted programs.

However, there's not forever a transparent distinction between malware and fewer threatening descriptors.

In a research paper distributed this month through pre-print server ArXiv, a pair of researchers from Concordia University in Montreal. Canada – Xavier de Carné de Carnavalet and Mohammad Mannan – show that in the case of software known as Wajam.


These categorical distinctions obscure how adware relies on the same untrustworthy techniques as malicious code.

"Adware applications generally not considered as much of a threat as malware," the researchers say, pointing to anti-virus applications. That label the code as not-a-virus, risk-aware, unwanted program or PUP.

"After all, displaying ads isn't thought of malicious activity. Consequently, adware has received less scrutiny from the malware analysis community."

On The Topic, Let Adware Be Treated As Malware Or Virus

The Canadian boffins argue that needs to change. Because Wajam, which injects ads into browser traffic, uses techniques employed by malware. Browser process injection attacks (man-in-the-browser) seen in the Zeus banking Trojan, anti-analysis and evasion techniques, anti-detection features seen in rootkits, security policy downgrading, and data leakage.

Also, over the past four years, the code has contained flaws. That exposes people using it to arbitrary content injection, man-in-the-middle (MITM) attacks, and remote code execution (RCE). Yet security companies remain reticent to apply the term malware too liberally. Because companies making dubious software have a history of suing. Recall in 2005 however spyware business Zango, currently defunct, sued Zone Labs for line its computer code what it had been.

Some More Information About the Adware And Malware History

"The line between adware and malware is a gray area," said de Carné de Carnavalet, a doctoral candidate in information and systems engineering at Concordia University in an email to The Register on Friday.


"Actually, the terminology has evolved in the past 15 years. Invasive adware also considered as spyware. Because of all the personal and sensitive data they collect. This wasn't the style of adware vendors WHO filed lawsuits against antivirus firms. Those firms currently merely use the terms 'adware' or 'potentially unwanted application'."

As a result, both antivirus companies and researchers rank the adware problem as a lower priority than. Let's say, ransomware, and even tend to leave it out. We hope to bring back the focus on this issue. It is still there, and it now has even more impact than before."

He adds that his paper also touches on vulnerabilities in adware. "It can have serious vulnerabilities, and nobody has incentives to report or fix them," he said.

Waja doin' with that sample? Working with professor Mohammad Mannan, de Carné de Carnavalet collected 52 samples of the ad injector Wajam. Which has gone by different names over the years – spanning from 2013 through 2018 in order to study? It's chronological evolution. The samples contain more sophisticated anti-analysis and rootkit-like features. That typically found in the most advanced malware.

Wajam, created by Montreal-based Wajam web Technologies, initial free in October 2011. The paper explains and rebranded as Social2Search in might 2016. Then renamed SearchAwesome in August 2017.

History About 2016 & 2017

In 2016 and 2017, the Office of the Privacy Commissioner (OPC) of Canada investigated the company. And its software and found multiple violations of the Canadian Personal Information Protection and Electronic Documents Act (PIPEDA). It made a series of recommendations to remediate violations, only to have the company sell. It's assets to Hong Kong-based Iron Mountain Technology Limited.

In a statement emailed to The Register. A spokesperson for Canada's OPC said the agency is aware of the Wajam research paper. And its analysis of the software.

"Our investigation looked at the matter through a more narrow privacy lens," the OPC spokesperson said. "During our investigation. We tend to found the practicality had additional to try to to with adware than sanctioning social media looking. In other words, the intent of the software was to serve ads to the user which is not. In itself, contrary to PIPEDA provided it done in accordance with certain legal principles."

"On the other hand, we generally view malware as malicious software. That can be harmful to computer users and their devices," the OPC spokesperson added. "It can include various types of programs. Which may install computer viruses, spyware, ransomware, can recruit computers into botnets or lead to crypto-currency mining (to name a few examples)."

What About OPC Spokesperson Said About Adware And More

The OPC spokesperson said several of Wajam's privacy practices contravene PIPEDA. Such as the company's failure to obtain meaningful consent to the installation of the software. Which resulted in the collection and use of personal information. The OPC also found the company prevented users from withdrawing. Their consent by making the software difficult to uninstall and by failing to take measures to safeguard users' personal information. It's not going away.


Despite these findings, eight years on, Wajam lives on, beneath associate degree alias and special legal jurisdiction. The Register emailed Iron Mountain Technology in the hope of discussing the software but we've not heard back.

"Advertising is not inherently bad, nor malicious," said de Carné de Carnavalet. "The ads displayed by Wajam don't seem to know to malicious either. However, Wajam could consider as malicious due to the personal data it collects. Insecurely, from users, including their browsing and download histories, and all search queries that the user makes."

He notes that it's doubtful users of Wajam, Social2Search or SearchAwesome would allow the software to operate as it does. If they understood how it works and how it collects information.

More About Malware And Ransomware

In a phone interview with The Register, Andrew Crocker, senior staff attorney. At the Electronic Frontier Foundation, said some of his colleagues have been arguing that sneaky software. Now commonly employed by governments in addition to the marketers and cybercriminals, they should look for common behavior rather than separated by prefixes like adware or ransomware.

"If you install software against the user's wishes or without the users' knowledge. That's the behavior of malware," he said, pointing to the Computer. Such as Fraud and Abuse Act, the Wiretap Act, and the Electronic Communications Privacy Act as potential avenues for legal challenges.

There are a couple of high-profile cases involving adware, last Lenovo's $7.3m settlement last year.

That it distributed Superfish adware on its PCs. But law enforcement authorities don't go after browser history thieves. With the same passion as credit card thieves or raiders of government databases.

To mitigate the threat posed by adware, de Carné de Carnavalet argues more. An effort made to warn people attempting to install adware. And that desktop platforms should adopt some of the same permission disclosures presented to mobile device users.

"You can't stop someone from writing an 'unwanted program,'" he said. "But such a program is a lot of seriously thought-about and higher detected."
