Are you at risk of KRACK while accessing public wifi?
20 Oct 2017
  • The next time you are browsing the wireless network at railway stations or airports, remember that your vulnerability to cyber attacks will be 'high'.
  • Devices based on Android, iOS, macOS, Linux and Windows are among those most at risk to a newfound vulnerability called KRACK.
  • A warning has been issued by the CERT-in, the nodal agency supervising cyber security in India.

  • How does India's track record in cybercrime look like?
    Stats
  • India's track record in cybercrime is far from satisfactory. In the first six months of 2017, CERT-in said 27,482 such cases were reported - one incident every 10 minutes, up from 2016's one incident every 12 minutes.
  • The most common crimes including phishing, virus or malicious code, scanning or probing, defacements, site intrusions, ransomware and denial-of-service.

  • Is the focus on public wifi a good idea then?
    Wifi
  • To push digitalization and connectivity, the government has been working on setting up public hotspots around the country: it launched a project to provide free hotspots in over 1,000 gram panchayats.
  • But it doesn't seem Indians are very concerned with security. In July'17, a report by Norton, anti-virus program seller, said 96% Indians put personal information at risk while browsing public wifi.

  • What are the commonly displayed risky behaviors?
    FACT
    The same report lists the risky behaviors people display in search for a stronger wifi signal: watching a three-minute ad (35%), allowing permission to access personal emails (19%), personal photos (22%), dating profiles (16%), contact lists (19%) and even edit social media profiles (19%).

    What's this thing called KRACK?
    Vulnerability
  • Recently, experts highlighted a vulnerability in WPA/WPA2 encryption, the most commonly used to connect to wifi, called a Key Reinstallation Attack (KRACK).
  • When you connect to a network, a 'four-way handshake' ensures the client and access point both have the correct login credentials.
  • KRACK exploits flaws in the protocol to find out the same installation key, which the attacker uses to access personal data.

  • Who's at risk of being attacked by KRACK?
    FACT
    According to Ram Swaroop, CyberSecurityWorks founder, "Every wifi network is at risk." Linux-based and Android devices on version 6.0 or higher are more vulnerable. This included over 40% of all Android devices.

    How can you keep yourself safe on public wifi?
    Steps
  • Swaroop says the safest option is to not use public wifi at railway stations or airports. But if you do, keep your devices and router firmware updated.
  • Refrain from updating apps on public wifi.
  • While browsing, check for a lock icon on the address bar to know if it's secure.
  • After browsing, 'forget' the network from your device.
  • CERT-in has recommended using VPN/wired networks.
