Last week, our researchers focused on an industry we regularly talk about here on Malwarebytes Unpacked: videogaming. First off, we covered news of Steam’s effort to improve the security of its users by introducing limited user accounts.

Our researchers also discussed TeslaCrypt, a now known ransomware that targets gamers, and how one should respond properly once affected. The main takeaway from the campaign is to regularly backup files, whether they’re game-, work-, or media-related.

Of course, no day is really complete unless we start talking about scams, and they are everywhere. The latest one we found and discussed are fake Instagram apps for Blackberry phones and highly suspicious “tools” used to hack into user accounts.

Finally, we pushed out a technical brief on what a zero-day campaign looks like and how the criminals behind it can be forward thinking at best and deliberately evasive at worse.

  • Wi-Fi Software Security Bug Could Leave Android, Windows, Linux Open to Attack. “The vulnerability is similar in some ways to the Heartbleed vulnerability in that it doesn’t properly check the length of transmitted data. But unlike Heartbleed, which let an attacker read contents out of memory from beyond what OpenSSL was supposed to allow, the wpa_supplicant vulnerability works both ways: it could expose contents of memory to an attacker, or allow the attacker to write new data to memory.” (Source: Ars Technica)
