“We are temporarily increasing our payout for Microsoft Outlook RCEs from $250,000 to $400,000. We are looking for zero-click exploits leading to remote code execution when receiving/downloading emails in Outlook, without requiring any user interaction such as reading the malicious email message or opening an attachment. Exploits relying on opening/reading an email may be acquired for a lower reward.” –Zerodium

The reward for Microsoft Outlook zero-click remote code executions (RCEs) has been doubled from $250,000 to $400,000. Zerodium, an exploit acquisition platform, has boosted its payout for Microsoft Outlook zero-click remote code executions (RCEs) from $250,000 to $400,000. The increase is a temporary tactic to achieve zero-click attacks, which can attack computers and networks without the need for human input. On its page for limited-time bug bounties, Zerodium explains the change.

Some assaults, such as phishing scams, necessitate user interaction, such as opening an email or email attachment. Because zero-click attacks don’t require user engagement, they’re more harmful.

Zerodium is a security firm that focuses on zero-day exploits and research. Its clients are mostly government agencies in North America and Europe.

The higher compensation for Microsoft Outlook zero-click RCEs started on January 27, 2022, although there is no set end date yet.

Trustwave talks of CVE-2020-0696 bypasses.
Links using URI schemes will trigger a warning box, and “:/” characters will be removed when transmitted to users, according to the CVE-2020-0696 fix. However, that change did not completely resolve the initial problem, and I later discovered a workaround.

The patch will strip “:/ ” from the link and transmit it to the user as “http://maliciouslink,” circumventing Microsoft ATP Safelink and other Email security programs, with the new exploit vector “http:/://maliciouslink.”

When the victim hits the link, it is automatically changed to http://maliciouslink and opened. This flaw can be used to compromise Outlook clients on both Windows and Mac OS X.
