Security experts are investigating an Egyptian hacker who goes by the name “Virus_Hima”, who released screenshots of potential flaws in Yahoo’s website. This has been done before by the hacker, whose intentions may or may not be good.
One of the flaws identified by this hacker included the ability to access a full backup of one of Yahoo’s domains. The other problems included a cross-site scripting (XSS) and SQL injection vulnerability, according to a PasteBin.com post “Yahoo data leak by Virus_Hima“.
Some of his previous work included Adobe, where he released a batch of more than 200 email addresses obtained from a database belonging to them. Adobe shut down Connectusers.com as a result, which is the Connect Web conferencing service.
Without his “good intentions”, it appears that he also has shut down the claim that he sold a $700 XSS vulnerability in the black market. He claims to be a former blackhat, and that his intentions are good as a vulnerability researcher. However, he was spotted in his PasteBin.com post to be taking shots at security reporter Brian Krebs, calling his site “Krebsonshitz” when it clearly is “Krebs on Security”. Krebs reported about the hacker back when the XSS vulnerability was being sold.
