Grifters find rich pickings on social networking sites
Social networking sites are creating a means for hackers and conmen to worm their way into the confidence of users.
Sites such as LinkedIn can be used to create a veneer of trust that leaves internet users and business at a greater risk of attack, according to a study by Danish security firm CSIS. Dennis Rand, a security researcher at CSIS, created a fictitious entry on the LinkedIn network before inviting random and unknown users of LinkedIn to join his private network. By posing as an ex-employee of "targeted" firms he was able to prompt real workers from these firms into establishing connections.
Within a few weeks Rand created a network of 1340 trusted connections. In a research paper, Threats when using online social networks (PDF), Rand explains how information gleaned through this network might be used to harvest email addresses for spamming or worse. The "blind trust" built into social networks might be abused to send messages containing links to malicious code that are more likely to be accepted because they come from a "trusted" source, for example.
Other risks include the possibility that sales staff might take sensitive sales prospect contact lists with them when they change jobs. Just putting these contacts online creates a data leak risk.
Rand's study focused on LinkedIn, a business-focused network with around 10m registered users, but the risks highlighted apply to social networking sites as a whole. He argues firms need to update their security policies to contain rules for using social networking sites.
Consumers also need to be wary about treating social networking sites as a safe environment. According to a recent Indiana University study, 72 per cent of recipients of spoofed phishing emails from social networking acquaintances failed to twig that something was amiss. But just 15 per cent failed to realise that a similar message sent by a stranger might be a scam. Data harvested from social networking sites might be used to personalise scam messages, thus increasing the plausibility of so-called spear phishing attacks.
In a recent interview, conducted by ha.ckers.org, a phishing fraudstere claims e could rake in between $3,000-$4,000 a day, by targeting users of social networking sites such as MySpace, Facebook and LinkedIn.
The stock-in-trade of this conman, who goes by the name 'Lithium', is to capture of login credential using bogus social networking sites, designed to resemble the real thing. He then accesses a victim's email account using captured login information, taking advantage of the fact that users often use the same password for multiple sites. Access to email accounts can be in turn be used to access any associated PayPal or eBay accounts.
This is a plausible enough scenario, even though Lithium's claimed spoils seem high. Perhaps the 19 year-old self-confessed fraudster feels the need to brag about his earnings. ®
LInkedIn / Facebook : Why not just email the CIA a daily update on your life?
Great sites, if you like exposing your social / business schedule, contacts list and more to all and sundry state and private US authorities wishing to spy on you or use the exposed data to gain commercial advantage or insight into your life / business.
Thank You Captain Obvious
If you lie to people on any forum you can build trust and then abuse that trust. Doe these guys really need press that badly that they would waste their time proving the obvious?
