Undead virus pilfered college servers for more than 10 years
The City College of San Francisco recently found a virus that had been taking banking and other data from students since 1999, proving a point about long-lived threats.
Most viruses have a pretty short life span, in biology as well as computers. But there are always exceptions to the rule. The mysterious “11-day virus” as the local news media are calling it, which I was lucky enough to experience this week, is one example.
But in the world of computers, long-term viruses are extremely rare. Most don’t even make it to the wild because the code they try to exploit has long since been patched or otherwise fixed before they launch.
Those that do successfully make a splash tend to infect a lot of systems quickly, but then the anti-virus companies or Microsoft catches up with them and makes them obsolete. With worldwide honey-pot networks just waiting to report on a new virus threat, the healing process can take mere minutes these days, so not a lot of viruses are given the chance to thrive.
Occasionally, an undead virus will come back to haunt us, as we found out with Stoned.Angelia in 2007.
That was a virus whose biggest accomplishment in the 1990s was finding a dark corner of the Internet to hide so it wouldn’t get completely scrubbed away. Then, about 10 years later, Windows Vista was launched with exactly the same vulnerability that Stoned.Angelia was designed to exploit. Suddenly, it came back to life and infected 100,000 systems before being put down again. And its hideout was never found, so it could still be alive, waiting for some bad bit of programming to set it free once more.
That’s impressive, but what about a virus that has been active and working for over a decade? Strange but true.
Recently the administrators at the City College of San Francisco noticed some discrepancies in their log files. When they checked it out, they discovered that a virus implanted on their systems in 1999 had been stealing bank info from students and staff members and sending transmissions to Russia, China and other countries for more than 10 years, Bank Info Security reported.
Although final numbers may never be known, at least one person on campus did have information stolen by the virus.
OK, it’s a little bit unforgivable that nobody would notice a virus operating for a decade, or even run a scan on systems during that time, but let’s forget about that for a moment. Since they didn’t want to give the virus a gold watch for longtime service, they instead took the server that it infected offline.
They also implemented several security plans, which are basically the kind of things they should have been doing the entire time on their network, such as adding new security hardware and software and dividing up servers based on the tasks they perform to make monitoring for anomalous activity easier.
It’s actually not surprising that a virus could live so long. Unless counterattacked by anti-virus programs, there is no reason to think that a working virus would suddenly disappear on its own. In that sense, it’s no different than the program that controls the traffic lights on your street.
I suspect that the virus at the college may have been put there by someone locally with knowledge of their systems, possibly even an ex-admin or a student aide. That’s why we review a variety of security programs in the GCN Lab that look at everything from mass-induced attacks from the outside to an internal threat from a mole bent on destruction from within.
Incidents like this one should remind everyone that the threats to your data and your productivity are real and multifaceted. Malicious programs never tire, never sleep, and unless found and attacked, never stop working against you.
