Who’s Hacking Who?

Update – The hacking map function seems to have been shut down – I got an error message “All access to this object has been disabled.

Who's Hacking Who?A new animated map of the Internet created by the U.S.-based computer security firm Norse helps cyber-defenders visualize where hackers are coming from and illustrate just how ubiquitous hacking is around the world according to a recent article by Maya Kosoff from BusinessInsider.

Norse logoSt. Louis-based Norse offers a product call IPViking which displays a map and lists of the countries doing the most hacking, the countries getting hacked the most, and the types of attacks happening. Quartz noted the animated map looks kind of like the vintage video game Missile Command.

Norse, founded by a former intelligence expert with the U.S.’s Department of Homeland Security explained to Smithsonian Magazine how the system works;

attacks shown are based on a small subset of live flows against the Norse honeypot infrastructure, representing actual worldwide cyber attacks by bad actors.

BI continues that the map doesn’t show all the hacking going on in the world, it could be a representative snapshot of today’s hacking ecosystem. A snapshot of the stats shows some of the baseline back-and-forth hacking attempts. Today, over 5 hours,

The top attack types:

  1. SSH port 22 – 6,308 attacks
  2. SIP port 5060 – 2,380 attacks
  3. Microsoft-DS port 445 – 2,317 attacks
  4. MS-SQL-S port 1433 – 2,193 attacks
  5. DNS port 53 – 2,182 attacks
  6. HTTP-Alt port 8080 – 2,007 attacks
  7. SNMP port 161 – 1,367 attacks
  8. MS-term-services port 3389 – 1,327 attacks

I have posted a couple of good maps on here before. This map relays a lot of good info while being mesmerizing also. The amount of malicious traffic flying at U.S. sites is staggering. The attacker’s emphasis is on basic network services, SSH, SIP, AD, SQL, DNS, HTTP, SNMP. Attacks on the basic services we rely on reinforce the urgency for U.S. network users to get their basics in order. The U.S. and China are locked in an escalating war about online spying that threatens to devastate business for companies in both countries.

Now for the really scary part. This IPViking map only reveals the tip of the hack-attack iceberg. It only shows penetration attempts against Norse’s network of “honeypot” traps. The real number of hack attempts lighting up interwebs at any given moment is far, far greater than this cool piece of big data mining can ever possibly show.

LinkedIn Accounts can be Hijacked

Help Net Security has a report that users of the newly minted public LinkedIn (LNKD) are in danger of having their account hijacked. The Linkedin accounts can be hacked when accessing them over insecure Wi-Fi networks or public computers. Independent security researcher Rishi Narang told Help Net Security that the risk is due to two reasons. First, the LinkedIn session and authentication cookies have an unnaturally long lifespan. Secondly, LinkedIn does not remove the cookies once the user logs out.

LinkedInThe article says the cookies in question are JSESSIONID and LEO_AUTH_TOKEN, and are available even after the session initiated by the user has been terminated. The cookies are also set to expire only after one solid year, and this fact allowed the researcher to get access to a number of active accounts of various people from all over the world during a period of many months. “They would have login/logged out many times in these months but their cookie was still valid,” Mr.Narnag writes on his blog.

In addition to all of that, those two cookies and the others that the welcome page stores are transmitted in clear text over HTTP, because they don’t have a secure flag set. “If the secure flag is set on a cookie, then browsers will not submit the cookie in any requests that use an unencrypted HTTP connection, thereby preventing the cookie from being trivially intercepted by an attacker monitoring network traffic,” explains Mr. Narang.

According to the researcher, until LinkedIn makes some changes, the only way to “expire” the cookies is for the users to change their password and then authenticate themselves with the new credentials. This could be a stopgap measure if you know that someone has stolen those cookies and is accessing your account, but won’t new cookies be created after the password change and authentication?

Help Net Security says that the only solution to this problem is for LinkedIn to effect some changes, and according to Reuters, they are planning to offer “opt-in” SSL support for the entire site in the coming months (and that would encrypt the cookies in questions), but have not commented on the cookies have such a long lifespan.
