Looking ahead, I have two goals for this newsletter. That means I’m not the journalist you want to sell ransomware snake-oil - unless you’re doing it at a security conference in the Aegean. I am a cyber-policy wonk turned journalist, and I come to this exalted post following a year researching ransomware in Greece. HAPPY Tuesday and CONGRATULATIONS! You’re the lucky winner of a special gift to lighten your post-Labor Day blues: an introduction to me, John Sakellariadis, your new MC host. Your MC host asked experts what aspects of the draft legislation they are most excited about. To submit a tech question, e-mail Rob at Follow him on Twitter at /robpegoraro.- Lawmakers will soon begin finalizing key cybersecurity provisions in the annual defense funding bill. Rob Pegoraro is a tech writer based out of Washington, D.C.

The phrase I’ve been using for the proper mindset since seeing it in a 2004 Ars Technica guide is ”skeptical computing”: bringing the same “oh, really?” attitude to strangers on the Internet that you would to strangers on the street.īut sadly enough, you can’t even trust friends on social networks if they haven’t gotten the skeptical-computing memo yet. You also need to remember that every e-mail and Web page telling you to do something now could be lying to you.Īnd when that urgent! warning comes from a strange source, it almost certainly is lying.

The usual security advice in a situation like this goes like “update your system and your browser, then get rid of dangerous software like Java and Flash.” It’s true - how many times have I told you to get Java out of your browser and uninstall Adobe’s Flash plug-in? - but it’s not enough. (I’m not naming him because I don’t want anybody to worry that sharing digital misfortunes will lead to them being publicly mocked by name.) How did this happen to my reader? He wrote that he had gotten a malware warning when he downloaded a strange e-mail referencing a flight purchase he didn’t remember making, then searched for a Microsoft security tool he was told (it’s unclear from his account by whom) that would fix the problem. Tip: “Trust No One” is a good policy for online solicitations As cybersecurity reporter Brian Krebs (a friend and former colleague at the Washington Post) wrote after I shared this reader’s story: “I wish I had a dime for every one of these sad reader e-mails I get.” I hope this column slows the problem but I fear it won’t. If so, better to pay them than the crooks. You may need to pay a computer store’s tech-support service for help with that. HIs advice: “Restore the box to a clean state but also to change all existing passwords (email, banking, etc.) which may have been compromised already.” “The machine affected has been compromised and cannot be trusted anymore,” Malwarebytes’ Segura wrote. Your only safe recourse is to have backups of your files - but not just any backups, since CryptoWall will attack any drives connected to the computer by a cable or network connection.Īnd that’s where this reader had one iota of luck: He had an external drive that was unplugged during the attack.Īs for the attacked computer, you pretty much have to nuke it from orbit. But CryptoWall comes set to wipe those files too.Ĭoughing up the ransom is no answer, wrote Jerome Segura, senior security researcher at Malwarebytes Labs: “Paying the crooks only contributes to fuel this underground economy.'īesides, as Buckholz wrote, “even if a victim pays, there's no guarantee they'll get their files back.”

Ullrich, dean of research at the SANS Technology Institute, suggested booting the computer from a flash drive running an anti-malware toolkit such as the one Trend Micro offers, then trying to recover the “shadow” copies Windows’ System Restore function automatically generates. “CryptoWall's use of unique keys for each infection makes it impossible to find a ‘one-size-fits-all’ solution to recover the encrypted files,” wrote Nick Buchholz, senior threat researcher at the Atlanta-based security firm Damballa.
