At least some applications on Fosshub, a free project hosting service appear to have been compromised, according to several reports. (Update: Fosshub has acknowledged the hack.) The software portal, furthermore, is serving malware payloads, reports add. Catalin Cimpanu of Softpedia says that a hacking group which goes by the name of PeggleCrew is responsible for the hack. "In short, a network service with no authentication was exposed to the internet," the hacker told Softpedia in an email. "We were able to grab data from this network service to obtain source code and passwords that led us further into the infrastructure of FOSSHub and eventually gain control of their production machines, backup and mirror locations, and FTP credentials for the caching service they use, as well as the Google Apps-hosted email." The hacker group told the publication that they have compromised the entire website, "including the administrator's email. He also revealed he didn't dump the site's database but claimed that "passwords weren't salted." A user on Reddit, who has since received lots of upvotes, adds: Some popular apps that have links to FossHub that may be infected include: Audacity, WinDirStat, qBittorrent, MKVToolNix, Spybot Search&Destroy, Calibre, SMPlayer, HWiNFO, MyPhoneExplorer, and IrfanView.Another application which has reportedly been compromised is Classic Shell. It is ostensibly overwriting the MBR on users' computers. Many users are upset with the timing of hack, noting that plenty of people were looking for Classic Shell amid the release of Windows 10 Anniversary Update. Update: 08/03 17:30 GMT by M :In a blog post, Audacity said that Fosshub was serving a hacked copy of its audio editing software for three hours. It adds that "no Audacity Team infrastructure was compromised." Fosshub team writes: Last night we had a security incident caused by a group of hackers that allowed them to log-in to FossHub developer *through* an user that was compromised. Shortly after, we noticed two users that were compromised. They simply logged-in using their passwords and this allowed them to escalate. [...] Several hours later, we noticed the attackers were able to gain access through an FTP account and we decided to shut down the main server immediately to prevent any further infection/damage. FossHub.com is down on purpose until we are able to identify the way hackers were able to escalate. Fosshub insists that the hacked copy of Classic Shell was only downloaded 300 times. In the meantime, if you know someone who may have downloaded the compromised copy of Classic Shell, here's what they need to do next.
