Canucks' ISPs routing data through snoop heaven USA

Does your ISP use a 'Boomerang route' to fling data into the NSA's lap?


A University of Toronto-led transparency project has criticised Canada's ISPs for unnecessarily routing user traffic via the US, even when both the origin and destination of the traffic is within Canada.

In a study that mirrors, in part, European concerns about why traffic should traverse the US when it doesn't need to, the Canadian transparency study blames an unwillingness to peer for sending traffic into the reach of the NSA.

The university's Andrew Clement and Jonathan Obar have put together the report along with an interactive map, in which they rate Canadian ISPs on various transparency characteristics. The ratings, the report says, are based on how easily users can find information including an ISP's compliance with data privacy legislation, how they report data access requests, how well they define personal information, information about where user data is stored.

Against the ten criteria used in the assessment, nobody scored highly: the best was Teksavvy, scoring just 3.5 stars out of a possible ten, followed by Primus on three stars.

None of the carriers tested provide transparency reporting, and the researchers say none of the 20 carriers they examined are in full compliance with Canada's PIPEDA (Personal Information Protection and Electronic Documents Act) privacy law.

About routing, the report states: “Fewer than half (8/20) of the ISP privacy policies refer to the location and jurisdiction for the information they store. Only one (Hurricane) gives an indication of where it routes customer data and none make explicit that they may route data via the US where it is subject to NSA surveillance”.

“Boomerang” routing – where data leaves Canada, traverses US networks (who might choose to ignore PIPEDA) and returns to Canada – accounts for as much as 25 per cent of traffic, the report states. The report claims that traffic traversing the US is “almost certainly subject to NSA surveillance”.

The key reason, of course, is peering, a discussion that will resonate with smaller ISPs around the world. If an ISP is unable to peer its traffic within Canada's TorIX (Toronto Internet Exchange) or OttIX (Ottowa), it may need to send data upstream through its transit provider to reach its destination.

    Surveillance tech faces trade limits as America syncs policy with treaty obligations

    More than six years after proposing export restrictions on "intrusion software," the US Commerce Department's Bureau of Industry and Security (BIS) has formulated a rule that it believes balances the latitude required to investigate cyber threats with the need to limit dangerous code.

    The BIS on Wednesday announced an interim final rule that defines when an export license will be required to distribute what is basically commercial spyware, in order to align US policy with the 1996 Wassenaar Arrangement, an international arms control regime.

    The rule [PDF] – which spans 65 pages – aims to prevent the distribution of surveillance tools, like NSO Group's Pegasus, to countries subject to arms controls, like China and Russia, while allowing legitimate security research and transactions to continue. Made available for public comment over the next 45 days, the rule is scheduled to be finalized in 90 days.

  • Global IT spending to hit $4.5 trillion in 2022, says Gartner

    The future's bright, and expensive

    Corporate technology soothsayer Gartner is forecasting worldwide IT spending will hit $4.5tr in 2022, up 5.5 per cent from 2021.

    The strongest growth is set to come from enterprise software, which the analyst firm expects to increase by 11.5 per cent in 2022 to reach a global spending level of £670bn. Growth has fallen slightly, though. In 2021 it was 13.6 per cent for this market segment. The increase was driven by infrastructure software spending, which outpaced application software spending.

    The largest chunk of IT spending is set to remain communication services, which will reach £1.48tr next year, after modest growth of 2.1 per cent. The next largest category is IT services, which is set to grow by 8.9 per cent to reach $1.29tr over the next year, according to the analysts.
